Radiation necessary in an early stage cancer
Comments

I'm firmly convinced that in another decade or so (yes, it will take at least that long), there will be FAR less use of radiation after lumpectomy, not only for DCIS, but for many with invasive disease as well. Everytime I think about it, I'm absolutely appauled how the use of radiation has risen to the level of frequency it's currently being used today.
As far as I can tell, there's really only one doctor (Silverstein), along with a few of his associates, who is spearheading the move to eliminate the excessive use of radiation after lumpectomy. That man is a hero in my view and I hope someday he is finally recognized by the entire medical community for his brave efforts. It isn't easy going against the flow, but when you're right and you know it, there's nothing else to do but keep pushing forward until they finally listen...and that's what he's doing.
He reminds me of another great team of Australian doctors, Warren and Marshall, who persisted for many, many years in trying to change what was then the prevailing medical dogma that ulcers were caused by such things as stress and spicy foods and the treatment was therefore, the elimination of stress and giving antacids. An abbreviated version of the story is here for anyone interested in reading it http://www.cdc.gov/ulcer/history.htm
It took one of them having to self infect himself with the H. Pylori bacteria, suffering through the development of ulcers from having done so and then curing himself with antibitocs for the medical community to finally wake up and listen to what those two were saying about the real cause of peptic ulcer disease. I believe he eventually recieved a nobel prize for his work. Well established medical dogma is hard to kill off. It took a very drastic measure by a very determined physician and a VERY long time, for them to finally listen...and even to this day, there are some older doctors that don't bother to test for H. pylori because what they learned in medical school is so ingrained in them that they can't accept what they learned was completely wrong.
I remember watching a patient with severe peptic ulcer disease literally bleed to death right in front of me back in the early 1990's . Recognizing in retrospect that the true cause and effective treatment for her disease HAD ALREADY been discovered many years before that point in time has always stayed with me. Not only was the medical community doing their best to ignore it all, they were also actively ridiculing those two brilliant physicians who were trying so hard to make the information known. It's something that I'll never forget and the day I realized this had all taken place, was the day I learned never to place 100% trust in established medical dogma.
Mark my words...they wil eventually come to the realization that radiation after all lumpectomy was a very bad idea.

I had a sentinnel biopsy and additional breast tissue removed two days ago. As of last night I had decided not to do rad. My tumor was 1cm, node neg, est + , prog-, HER2-. My surgeon called today to say that the margins were not clear. This has radically shifted my thinking. I am 36 years old and my thought at the moment is that I need to be sure that the cancer is GONE from my breast, even though I know that there is no guarantee that it won't come back. I almost can't bear the thought of them doing surgery for a 3rd time on the same area with no guarantee that they will get all of the tissue. I also realized after speaking with my husband that although he supported me 100% when I said that I didn't want to do rad, he is very scared. I'm still on the fence, but now leaning toward radiation. I am thankful that this discussion is out there though.

Me update. (A few hours after chemo and med onco visit. A little wobbly.)
I opted for breast conservation/lumpectomy, and had re-excision and micromet to one lymph node. Am now undergoing dose dense AC/T. Was having reservations about rads for reasons mentioned above. I live an extremely happy and fulfilling life. I do not have children. I am not married.Okay, since my original post, I found out I have BRCA2 gene mutation. So risk of recurrence, new primary, etc. is higher.
After talking to my med onco (whom I trust and has specifically told me that she never wants me to blindly and completely put my faith in my doctors but to keep asking questions...) and the gene counselors and docs, I have decided on the following course of action:
1. Stick with the breast conservation/lumpectomy. If I have a recurrence, new primary, etc. I will consider a masectomy (or two) at that point. My med onco feels pretty strongly about that.
2. I will have radiation. If masectomy and reconstruction are necessary down the road, it will be with tissue rather than implants, something that -- to the extent I wind up going that route -- would be my preference anyway, I think.
3. I will have my ovaries removed after I finish chemo but before radiation. This will lower my risk of recurrence or a new primary.
4. I will have a few more lymph nodes removed during that same surgery. I will make it clear during consent that I am not game for lots of nodes being taken out. (God, I do not want to deal with LE.)
5. I will take Tamoxifen.
I'm okay (right now, when the possibility of more cancer is an abstraction) with realizing later that I could have made a better, different set of decisions. But these are the decisions I feel good about making now and I feel like I am making them from a place of strength and confidence in myself, not (just) fear of the unknown.
bfkh2t: I don't know your situation. But I want you to know that in most cases, there is time, time, time to think about things. You don't have to know what you're doing right now. Take your options for a test drive!2 re-excisions are not unheard of -- I wonder if surgeon is a skimpy margin kind of gal/guy-- but boy, I can understand why this might rattle a person! I don't go to "nervous wreck" very often, but that.... The fact that you found us and posted here given all that is going on, your recent surgery, etc. -- that is really admirable.
You take good care, and know that there are people here (with a lot more experience than me) to lend you support and sound advice if you want it.

Yeah, I feel great with my all clear mammo! And without ever having to subject my body to any of these other "treatments." With all of their horrible, side effects.
Although, I'm not, stupid. I'm going to continue with mammograms and MRIs for the forseeable future. On a frequent basis. And if the breast cancer, comes back, I'll deal with it, surgically, again.
There ARE a lot, of unknowns. But when I finally delved in, to the numbers in the "real" studies the docs were quoting, to me, as "proof" that I "needed" this radiation, it wasn't compelling, to me. For one thing, most of these studies, were thirty years old. And nowadays, Digital Mammography can reveal the tiniest cancer. Or pre-cancer.
Yet, they won't do any more studies comparing Lumpectomy alone, or Lumpectomy with radiation. In the US, they haven't done one, in 30 years. Because it was "so proven" to be effective.
Ha, so "proven" to be a $MoneyMaker.
In 2006, I found this Austrian study, on the benefit of radiation after lumpectomy vs none, right here on breastcancer.org. For 1cm cancers, HR/PR+, HER-, negative nodes. If you look around, you can find it. And that study said, I don't have the exact quotes, but something like if you have the radiation, in absolute terms, there's a 2% chance the breast cancer, will return. If you don't, it's 4%.
Although, in the popular media, the headline would read, "50% decrease in breast cancer recurrence, with radiation therapy."
And that's all most people, read.
Hey, any of you women out there, questioning, radiation therapy? Again, with small cancers, in my view, 2CM or less IDC, ER/PR+/HER-, negative nodes. That's the only thing I can speak to, because it is what I had.
If you're in that boat? DO NOT do, the radiation. And DO NOT do, the Tamoxifen.
It's NOT worth it.
I know, there's a LOT of women, in a lot of other boats. Triple negative, whatever. You do, what you need to do.
I'm just speaking to the women, like me. Don't do it.

You said "My surgeon called today to say that the margins were not clear. This has radically shifted my thinking."
Considering the above, you're very wise to reconsider not wanting to do radiation. Having unclear margins, and especially if you happen to have margins that have been cut through, is a factor that would make radiation after lumpectomy a more reasonable choice. The only other reasonable alternative to avoiding radiation would then be a mastectomy.
I know my postings make me sound as if I'm adamantly opposed to radiation after lumpectomy - but that's not exactly true. What I'm opposed to is the standard of care that's causing lumpectomy to automatically equal radiation in all or most cases without much, if any, consideration for the numerous variables that exist among individual cases. Unclear margins, and especially margins that have been cut through, are a clear indication that lumpectomy alone will have a fairly significant risk of recurrence, far higher than if margins had been cleared with the first surgery. Even clearing the margins with additional surgery doesn't necessarily bring that risk down to the level if would have been had they been cleared initially.
As MDB mentioned, for some people with small, low grade tumors and clear margins, not only is the risk of recurrence relatively minimal, but the risk FROM a recurrence of that same low, grade cancer is considerably less than for someone with a different, more aggressive pathology.
Take as much time as you need to feel confident in whatever decision you make. There's really no big hurry to make the radiation decision. Best wishes.
-
I genuinely appreciate the voices of caution (and "adamant opposition" to) radiation, to be honest. At the very least, they prompted me to ask (and I will continue to ask) questions of my doctors that I wouldn't necessarily have asked otherwise and put them on notice that "I'm not going to buy or do everything you say just because you're a doctor. I'm the one who will have to live with my decisions."
-
I want to say thanks to all those who have given advice. It has all helped. I strongly believe in dealing with this as non-invasively as possible. The truth is that I don't feel I have time to think about this much. I was accepted into a PhD program with full tuition paid via a teaching assistantship. I am supposed to move in mid-August. I know it sounds extreme, but I am willing to risk almost anything to take the opportunity. It has been a lifelong dream and I can't imagine giving it up. Having said that, it seems like radiation is my best chance...mostly because of my age and the unclear margins. I meet with the med onco for the first time on Monday. Wish me luck and thanks so much to all of you brave and wise souls out there fighting onward!!!

bfkh2t -- As the former chair of a grad program, I have known of many cases where a grad program would defer your admission + tuition/stipend under these circumstances (whether to January or to the following fall). Don't rule out asking them. Depending on how much you want them to know, you might direct your request to either the dean of the grad program, or the director of grad studies for your particular program.
Also, while I hope it wouldn't be necessary, I have requested & received unpaid leaves of absence for my students who have experienced a serious medical problem (e.g., they don't have to pay a matriculation fee).
Just something to think about. CONGRATULATIONS!

We all need to follow our instincts as far as our treatment goes. I blindly followed my doctors advice and had rads, even though I kept questioning it throughout. I had clear margins and nodes and I just did not see the point. I don't even feel a sense of comfort that the rads did me any good because I really feel that the diet and exercise program that I am on has helped me the most. I have not seen any of my doctors for a follow up and will not go back to my onc, ever. I just did not feel supported enough by them. I found a great holistic doctor (chiro) who is helping me naturally regulate my estrogen and I did a thermograph instead of another mammo because I am so afraid of even more radiation. This has to be decision that we make from our hearts and unfortunately, that doesn't hold any merit in the AMA.

Last year when I was first diagnosed and had to go back for more surgery because they didn't expect what I had to be DCIS and it was. Well the second surgery showed Atypical Ductal Hyperplasia with no clear margins. And my Oncologist gave me the option of Rad or not and I felt that since there was only ADH and no DCIS and my follow up mammo was ok that I could do the Tamoxifen and forgo the Rads. Well I had another clear mammo in July of last year and moved on with my life. And then in Jan of this year they did another follow up and Boom two new calcification's and one was ok and one was more DCIS that was not there in July of last year. That scared me because of the rate of growth that this thing had and this one was worse then the one they found last year. I still have some doubts about rads and may have opted for bilateral with reconstruction but I think my family is also not ready for that yet. I am not sure but I have other issues that had to be addressed too and would take way to long to go into here. I agree it should be your choice weather to get it or not but if you don't please make sure you keep up with your mammos. It seems the little buggers just jump out and bite you when you least expect it. I do know that if I get more of this on this or the other side that is it for me and I want to have a bilateral. I am only 47 and I think living with this unknowing fear is worse then the loss of my breasts. My Doc still says that he feels my option to not do rads last year was a good one and this was so unexpected, but then again that is me for ya.. I am murphys law
Just my two cents.... your millage may very..

Hi gals, I think, just think, don't know for sure, that the rad oncs either do not know what can happen, or don't want to scare you away from a treatment that can save you a recurrence.
Some women have rads and not one single side effect. I did not burn at all, just got brown, BUT, I ended up with rib problems. So this is the reason it is so hard to know what to do. The benefits are pretty well proven, they just need some way to be able to tell who will have lung damage, heart damage, rib damage, etc. One thing I tried to do and would INSIST on now (after the rib damage) is make them give me an apron to slide under my breast and covering my abdomen and heart, and, most of the lung.
They insisted that "nothing goes anywhere except the breast", and they were wrong. I asked for the apron, if I knew then what I know now, I would MAKE them let me have one. If it doesn't matter, what can it hurt?
Sheesh, I love medicine.
Hugs, Shirlann
-
Thanks, Shirlann. I'm going to keep this in mind.
Has anyone ever had "prone" rads (on my stomach, I think)? (I used to smoke cigarettes.)
-
Shirlann,
After reading all I've read thus far on the subject over the last 4+ years, I'm firmly convinced that the rad oncs know exactly what the potential consequences are. When you read research reports and literature submitted to medical journals written by radiation oncologists, they almost always downplay and otherwise minimize consequences and focus on emphasizing the continued need for radiotherapy - similar to what pharmaceutical companies do when they're marketing their patented drugs.
And you're absolutely right - that line about "nothing goes anywhere except the breast" is pure B.S. I can show you a stack of journal articles speaking to the contrary...and not just regarding radiation in years past either. It's a continued problem and an ongoing concern in trying to figure out how to minimize the radiation to areas it's not suppose to be affecting, but still does despite more recent improvements in the delivery.

As someone who has opted for no rads I find this thread very interesting. I was diagnosed with DCIS 5 years ago and so far, so good.
However, EVERYTHING I read says that ALL studies show rads to be beneficial (i.e. lowers recurrence rates) in ALL cases. There is no subset that rads does not help. Could someone (maybe MarieKelly or MarieS or mdb, as you seem very knowledgeable in this area) point me in the right direction where I can find studies that show this is not the case? Or are there no such studies? Is it simply because of the long term possible side effects that rads shold be discouraged? I have Dr. Silverstiein's big textbook but really, he is the only one who seems to be advocating this. I am amazed at the number of women who are diagnosesd with tiny areas of DCIS and good margins who go on to have radiation with a blessing and big push from their doctor, and even moreso, those who have double mastectomies.
Five years after the fact I am still confused about this and question whether I did the right thing. I chose no rads as I had a tiny area of dcis and most doctors I saw said I could do without. The only who told me I MUST have rads was the radiation oncologist. Also, I fell into a severe depression after my diagnosis and felt very unempowered to make any kind of decisions. I am definitely not a big risk taker and had I had doctors who were willing to work with me a little more and listen to me and answer my questions I may have chosen to have radiation therapy. Also, had I been given the opportunity to have the mini-rads, not sure of the real name, I very well may have chosen that.
(Just an afterthought that occured to me - seems most studies show in stage 0 or 1 rads cut the recurrence back by 50%. If rads were given to perfectly healthy women with no bc would their rate also be cut by 50%?)
-
Since I had a mastectomy and one positive node, that's where most of my research has been focused. Until recently, the rad onc profession made a distinction between mastectomy patients who had 4+ nodes, and those with 1-3. The 4+ patients were considered those who would receive high benefits from radiation, but the benefits were less clear for the 1-3 node patients. The rad onc profession now is moving to abolish this distinction, as an editorial in the May 2008 Journal of Clinical Oncology, Vol 26, No. 13, states:
"We believe thatcomprehensive PMRT [Post Mastectomy Radiation Treatment] is appropriate for the great majority ofnode-positive patients undergoing mastectomy. Some selectionbased on other clinical and biologic factors may be importantand appropriate. For example, Cheng et al29 developed a modelto predict locoregional recurrence and the impact of PMRT onsurvival. In addition to axillary nodal status, estrogen-receptorstatus, lymphovascular space invasion, and age at diagnosiswere all found to be significant. Similarly, Truong et al30 suggested that young age, medial tumor location, ER-negativestatus and greater than 25% of nodes positive were also predictorsfor a higher risk of locoregional recurrence. It is likely thatother more sophisticated biologic factors, such as gene expressionprofiling, will also be helpful in this regard."
I have read the two studies referenced in the editorial by Cheng and Truong:
- Cheng SH, Horng CF, Clarke JL, et al: Prognostic index score and clinical prediction model of local regional recurrence after mastectomy in breast cancer patients.Int J Radiat Oncol Biol Phys 64:1401-1409, 2006[CrossRef][Medline]
- Truong PT, Olivotto IA, Kader HA, et al: Selecting breast cancer patients with T1-T2 tumors and one to three positive axillary nodes at high postmastectomy locoregional recurrence risk for adjuvant radiotherapy. Int J Radiat Oncol Biol Phys 61:1337-1347, 2005[CrossRef][Medline]
In each case, they went beyond the number of positive nodes, and sought to identify women who were at low, medium, and high risk of recurrence. Each found certain factors, as summarized in the editorial above, were predictors for a risk of recurrence.
The Cheng study states: "In the low-risk group, there is no influence of PMRT on either LRR (locoregional recurrence) or survival."
The Troung study concludes, "The absence of high-risk factors identifies women who may reasonably be spared the morbidity of PMRT."
I agree whole-heartedly with Marie that the rad onc profession systemically downplays the risks involved and pushes only the benefits of rad therapy, even if the potential benefits are small to non-existent and the risks for s/e like lymphedema are high. The first rad onc with whom I met never even mentioned lymphedema as a risk - and this was at a major breast center!!
A good article about the incidence and risk factors of lymphedema after PMRT is: Lymphedema Secondary to Postmastectomy Radiation: Incidence and Risk Factors, Annals of Surgical Oncology, Vol. 11, No. 6, 2004.
I have one last consultation with a rad onc this coming Monday, but unless she is extremely persuasive and can give me facts and figures showing me that the potential benefits of rads outweigh the potential harm, I will be opting against radiation. I've been through a bilat mast, 6 TAC chemo, and will be getting hormone therapy. I had clean margins, no extranodal extensions, and no vascular involvement. From what I've read, rads will give me little if any additional protection, and have the potential to leave me with permanent s/es. Enough is enough.
-
Very interesting thread to me since I have only had one rads consult and need to schedule at least one more. I'm curious if any of you who declined radiation had invasive lobular. My oncotype score was 17 and both oncos I consulted were pretty adamant about chemo and radiation although I am stage 1 with a 2cm tumor removed (lumpectomy, no positive nodes.)
-
Hi. I also find this thread interesting. Like OldOakTree, I did not have rads recommended to me. My docs said that it's not they they wouldn't benefit me, it's that the % was not really worth it. Same with tamox, but I am on that anyway. My risk of recurrence was about 6% in ten years. They go to 10 years with DCIS because it usually takes longer to come back. About 3% dcis, 3% invasive for someone with my pathology. Rads would lower that number by 50% to 66%. Mel Silverstein does recommend rads to many of his lumpectomy patients, just not the ones whose DCIS areas were less than 5mm, with 1 cent margins and lower grade. Like, Marie Kelly, I think that he's on his way to changing the way we look at small lesions.Unfortunately, most of the time, DCIS is not found that early or is just a faster growing type.I know that Silverstein and Lagios are pretty much the only ones, but it is a very important study that has now been followed for a few years by prominent docs in big cities. I live in Chicago and I found at Northwerstern hosp that were quoting Silversteins studies. No rads for lower grade, large margins, and small focus. Hope my info helps. I have to believe I did the right thing. Three opinions can't all be wrong! I don't know anything about no rads and invasive, though, I belive that if your margins are really large and clean, you need to really analyze the situation and not just jump. Nada
-
Well, I can only bring my small knowledge.
RE; nada's study, I fell on the wrong side of Silverstein % and did the rads, since I had clean margins, but mine was high grade. One loose high grade dcis cell, can lead to a very agressive IDC... (I had minimal SE from rads).
There are some possible long term problems with radiation, BUT, statiscally we all have a much larger chance of BC coming back than having the radiation issues.
I asked my onc (with his knowledge) if his wife had what I had, dcis, would he recommand her the treatment. He admitted that she had dcis, and did 35 tx, and took the tamoxifen. So, with is knowledge of possible post-rad-problems he still found the benefits outweighted the risk in his wife's case.
Results: I can worry a bit less about BC and I added a slight bit or worry for Sarcoma... It is all about the size of the 'bits' I guess.
Boy, can I make things more convoluted.

Yes indeed, there definately ARE such studies...for both DCIS and invasive disease as well. First of all, literally all studies show that most don't benefit from the addition of radiation therapy - it's just that the emphasis in studies is never about how many didn't have a recurrence without radiation. The emphasis and focus is placed on the difference in recurrence between having radiation or not having it.
When a study shows that, for example, in a group of 100 who didn't recieve radiation there were 18 recurrences but only 9 in the 100 who did recieve radiation, the emphasis is on that difference. The fact that 82 (the vast majority) out of those 100 who were not radiated didn't have a recurrence is de-emphasized making it seem almost irrelevant..unless of course, that happens to be the information you want to know. But in reality, those 82% would not have recieved any recurrence benefit from having radiation.
Here's some journal information for you -
For example -
http://www.annalssurgicaloncology.org/cgi/content/full/11/3/316
"An ideal group of 80 breast cancer patients was empiricallydefined for avoidance of adjuvant radiation after BCS on thebasis of older age (>50 years), smaller size (
1.5 cm), lowergrade (grade 1 or 2), and adequate surgical margins (
1cm). The local recurrence rate was only 6% after a median DFSof 64 months (range, 15-86 months). Median follow-up was61 months (range, 1-174 months); only one patient wasDOD. When patients from the unknown group (grade or margin datanot available) were included in the ideal group, the expandedideal group of 96 patients had a local recurrence rate of 5%and a median DFS of 64 months (range, 15-86 months). Themedian follow-up was 59 months (range, 1-174 months),and no additional patient was DOD. In patients who had one ormore nonideal characteristics, the local recurrence rate was22%.
Consideration should be given for BCS without adjuvant breastradiotherapy in such selected ideal patients after a thoroughdiscussion, including a description of standard alternativesand risks and benefits of radiotherapy. If treated with surgeryalone, these patients would still be candidates for radiotherapyin the future if local recurrence occurred. Patients not inthe ideal group should be considered for adjuvant radiotherapyafter BCS.": Eur J Surg Oncol.

Is radiotherapy needed after breast conservation for small invasive breast cancers?
Athow AC, Gattuso JM, Perry N, Wells C, Dutt N, Bahsir GM, Mair G, Carpenter R.St Bartholomew's Hospital, West Smithfield, London, UK.
AIMS: The purpose of this study was to determine the rate of local recurrence in patients with small invasive breast cancers (<1 cm) who had been treated with breast-conserving surgery either with (group 1) or without (group 2) adjuvant radiotherapy. METHODS: This is a retrospective study of 110 patients with an invasive breast cancer less than 1 cm in size, treated in our centre by breast-conserving surgery. Parameters examined included age at and mode of presentation, histopathological features, adjuvant therapy, length of follow-up and outcome in terms of local recurrence rate and death. RESULTS: In group 1 there were 59 women of median age 57 (38-80) years. The median tumour size was 9 (1-10) mm and median follow-up was 74 (15-110) months. There were no local recurrences. In group 2 the median age at presentation was 59 (48-81) years. The median tumour size was 7 (2-10) mm and median follow-up was 47 (14-93) months. There were three non-breast-cancer related deaths and three local recurrences (6%). CONCLUSIONS: A local recurrence rate of 6% at almost 4 years median follow-up suggests that it may be possible to avoid adjuvant radiotherapy in a subgroup of largely screen-detected, node-negative patients with invasive tumours less than 1 cm, in whom adequate local excision is performed. Further follow-up is required to substantiate this. Copyright 2002 Elsevier Science Ltd. All rights reserved.

Breast conservation surgery, with and without radiotherapy, in women with lymph node-negative breast cancer: a randomised clinical trial in a population with access to public mammography screening.
Malmström P, Holmberg L, Anderson H, Mattsson J, Jönsson PE, Tennvall-Nittby L, Balldin G, Lovén L, Svensson JH, Ingvar C, Möller T, Holmberg E, Wallgren A; Swedisj Breast Cancer Group.Department of Oncology, Lund University Hospital, S-221 85, Lund, Sweden. per-olof.malmstrom@onk.lu
The effect of postoperative radiotherapy after sector resection for stage I-II lymph node-negative breast cancer was evaluated in a patient population with access to public mammographical screening. 1187 women were randomised to no further treatment or postoperative radiotherapy following a standardised sector resection and axillary dissection. Radiation was administered to a dose of 48-54 Gy. Median age was 60 years, and median size of the detected tumours was 12 mm. Of the women 65% had their tumours detected by mammographical screening. The relative risk (RR) of ipsilateral breast recurrence was significantly higher in the non-irradiated patients compared with the irradiated patients, RR=3.33 (95% Confidence Interval (CI) 2.13-5.19, P<0.001). The corresponding cumulative incidence at 5 years was 14% versus 4%, respectively. Overall survival (OS) was similar, RR=1.16 (95% CI 0.81-1.65, P=0.41), with 5 year probabilities of 93 and 94%, respectively. Recurrence-free survival (RFS) at 5 years was significantly lower in the non-irradiated women, 77% versus 88% (P<0.001). Although women above 49 years of age, whose tumours were detected with mammographical screening, had the lowest rate of ipsilateral breast recurrence in this study, the cumulative incidence of such event amounted to 10% at 5 years if radiotherapy was not given. Such a recurrence rate has been considered as unacceptably high, but is, however, in the same range as that reported after lumpectomy and postoperative radiotherapy in published series.

The role of radiotherapy in treating small early invasive breast cancer.
Varghese P, Gattuso JM, Mostafa AI, Abdel-Rahman AT, Shenton KC, Ryan DA, Jones JL, Wells CA, Mair G, Kakkar AK, Carpenter R.Breast Unit, St Bartholomew's Hospital, Queen Mary University of London, London, UK. drphilipv90@yahoo.com
AIM: The aim of the study was to identify if radiotherapy can be safely avoided in a selected subgroup of largely screening detected small invasive breast cancer. METHODS: One hundred and eighty-eight patients with node negative invasive early breast cancer < or =1cm (< or =T1b) treated in our centre between 1990 and 2004 were retrospectively followed for local, regional and distant recurrences. Treatment involved adequate local excision by breast conserving surgery (BCS). Axillary staging was performed by a four node axillary sampling until 2000, following which sentinel lymph node sampling was employed. All sections were assessed histologically by haematoxylin and eosin stained sections. The inked margins were reported as being involved, close and clear. Radiotherapy (RT) was employed only if the resected margins were inadequate, and in those with involved axillary nodes who refused further completion axillary clearance. RESULTS: Ninety-four patients (Group A) had BCS alone and 79 patients (Group
had both BCS and RT. There was no ipsilateral breast tumour recurrence (IBTR) in 88 patients in Group A, corresponding to an actuarial freedom from IBTR of 96%, 91% and 88.1% at 5 years, 8 years and 9 years. In Group B, there was no IBTR in 75 patients corresponding to an actuarial freedom from IBTR of 97%, 94.9% and 90.6% at 5 years, 8 years and 10 years. CONCLUSION: Our experience over 14 years has shown that it is possible to safely avoid radiotherapy in a selected subgroup of small invasive breast cancer.

10-Year results after sector resection with or without postoperative radiotherapy for stage I breast cancer: a randomized trial.
Liljegren G, Holmberg L, Bergh J, Lindgren A, Tabár L, Nordgren H, Adami HO.Department of Surgery, Orebro Medical Center Hospital, Orebro, Sweden. goran.liljegren@orebroll.se
PURPOSE: To study the long-term effectiveness of postoperative radiotherapy after sector resection for breast cancer in a randomized trial in which mammography is a major pathway to diagnosis. PATIENTS AND METHODS: Three hundred eighty-one women with a unifocal breast cancer < or = 20 mm in diameter on the preoperative mammogram and without histopathologic signs of axillary metastases were treated by sector resection plus axillary dissection. Of these patients, 184 women were randomized to receive postoperative radiotherapy to the breast (XRT group), and 197 women received no further treatment (non-XRT group). RESULTS: The local recurrence rate was 8.5% (95% confidence interval [CI], 3.9% to 13.1%) in the XRT group and 24.0% (95% CI, 17.6% to 30.4%) in the non-XRT group (P =.0001). Survival free from regional and distant recurrence was 83. 3% in the XRT group (95% CI, 77.5% to 89.1%) and 80.0% in the non-XRT group (95% CI, 73.9% to 86.1%) (P =.23). Overall survival was 77.5% in the XRT group (95% CI, 70.9% to 84.1%) and 78% in the non-XRT group (95% CI, 71.7% to 84.3%) (P =.99). A subgroup analysis suggested that women older than 55 years of age without comedo or lobular carcinomas had a low risk of local recurrence of 6.1% (95% CI, 0.1% to 9.1%) in the XRT-group and 11.0% (4.0% to 18.0%) in the non-XRT group (P =.16). CONCLUSION: Sector resection plus radiotherapy resulted in an absolute reduction in local recurrence of 16% at 10 years compared with surgery alone. Women older than 55 years of age without comedo or lobular carcinomas may have a low risk of local recurrence. Postoperative radiotherapy was not shown to reduce distant recurrences or improve overall survival.

Factors associated with local breast cancer recurrence after lumpectomy alone: postmenopausal patients.
McCready DR, Chapman JA, Hanna WM, Kahn HJ, Yap K, Fish EB, Lickley HL.Department of Surgical Oncology, University Health Network, Princess Margaret Hospital, University of Toronto, Ontario, Canada.
BACKGROUND: We have been following a cohort of patients who underwent a lumpectomy without receiving adjuvant radiotherapy or adjuvant systemic therapy. We now report the experience of a postmenopausal subgroup. METHODS: The postmenopausal subgroup included 244 patients accrued between 1977 and 1986 and followed up. The end point was ipsilateral local breast cancer recurrence. The factors studied were the patient's age in years; tumor size (in mm); nodal status (N-, Nx, N+); estrogen and progesterone receptor status (< 10, - 10 fmol/mg protein); presence or absence of lymphovascular/perineural invasion; presence or absence, and type, of DCIS (none, non-comedo, comedo); percentage of DCIS; histological grade (1,2,3); and nuclear grade (1,2,3). Univariate analyses consisted of Kaplan-Meier plots and the Wilcoxon (Peto-Prentice) test statistic; the multivariate analyses were step-wise Cox and log-normal regressions. RESULTS: The median follow-up of those patients still alive was 9.1 years, and the overall relapse rate was 24% (59/244). The univariate results indicated that the characteristics of smaller tumor size, negative nodes, positive ER status, and no lymphovascular or perineural invasion were associated with significantly (P <.05) lower relapse. From the multivariate analyses, the factors lymphovascular or perineural invasion, age, and amount of DCIS were all significantly associated with local relapse with both Cox and log-normal regressions. Additionally, there was weak evidence of an association between ER (P = .08 in the Cox regression and in the log-normal) and nodal status (P = .09 in the log-normal regression) with local relapse. We also are able to define a low-risk subgroup (N-, age -65, no comedo, ER positive, no emboli) with a crude 10-year local recurrence rate of 9%. CONCLUSION: With longer follow-up, and for postmenopausal patients, there continues to be support for the theory that local relapse is affected by the factors lymphovascular or perineural invasion, age, amount of DCIS, ER, and nodal status. A low risk subgroup has been identified.

Multidisciplinary management of ductal carcinoma in situ: a 10-year experience.
West JG, Qureshi A, Liao SY, Sutherland ML, Chen JW, Chacon M, Fanning C.Department of Surgery, Breast Care Center at the Cordelia Knott Center for Wellness, 230 S Main St, Orange, CA 92868, USA. jwest@breastcare.com
BACKGROUND: Two ductal carcinoma in situ (DCIS) treatment controversies are (1) what is the preferred margin for patients undergoing lumpectomy plus radiation, and (2) is there a subgroup that can be safely treated with lumpectomy alone? A multidisciplinary team was established to evaluate these issues. METHODS: Patients with DCIS who were candidates for breast-conservation were divided into 2 groups. Group 1 had a minimum 5-mm margin and received radiation, and group 2 had a minimum 10-mm margin and received no radiation. RESULTS: One hundred fifty-two patients (153 cancers) met the inclusion criteria. The median follow-up was 8.2 years. Overall, there were 6 recurrences (3.92%); 1 of 71 recurred in group 1 (1.40%), and 5 of 82 recurred in group 2 (6.01%). CONCLUSION: Five-millimeter margins plus radiation results in low rates of recurrence. A subgroup of DCIS patients can be identified in which radiation can be safely avoided. The multidisciplinary team approach to managing DCIS enhances the potential for improved outcomes.

I have such a gut feeling that I DO NOT want to do rads, and yet, looking objectively at the information available out there, I am someone who probably "should" get radiation. I am 46 yrs old. In March, a routine mammogram showed clustered microcalcifications in the rt breast. I had a stereotactic biopsy in April - pathology was high grade DCIS. I had a lumpectomy 5/23/08. Margins clear, no invasiveness. . .but, DCIS, high grade, comedo necrosis, spanning 5 cm.
I met with the radiation oncologist two days ago. He said in cases such as mine, radiation was highly recommended. In reading through this thread, it seems those of you who have declined radiation after lumpectomy have had lower grade DCIS and < 2cm.
I am still on the fence, but I will probably be heading in for my "sim" appointment on Monday. I can't thank the women on this site enough for sharing all of their considerable experience and research!
Of course, I still wish I could get that divine "right" answer about what to do.
Many thanks. Jess. -
Dear Ladies,
I was just diagnosed with tubular breast cancer in the very early stages. My BS called Friday with the results of the wire loc biopsy I had done on June 12th. She is scheduling me for more surgery to check the margins and remove 2 lymph nodes to make sure they're clear. She said the tumor(s) were very tiny and we caught this at a good time. My post op appt with her is this coming Wednesday. I'm going to ask for copies of all the reports at that time. She has also referred me to a rad oncologist since she is recommending rad therapy. They already called and left me a message to call and make an appointment.
I am 49 years old and this is my 3rd go around with cancer. The first time, I was 29 and grew a tumor the size of a grapefruit in my neck. Had 6 months of chemo and rad therapy then. The 2nd go around was in '05, started growing milignant tumors in the soft tissue of my right shoulder (same area that I was radiated when I was 29). I had 4 tumors over the course of two years. All were surgically removed with some muscle replacement as well as having the scapula trimmed (the bone had broken through the skin and I had a small hole in my back).
I am seriously considering saying no to the rad therapy. I will meet with the rad oncologist to hear what he has to say before making a final decision. I'm thinking that at this point in time, I don't have enough information.
I've read all your posts this morning and it's been a lot of help. I's like to hear back from you with your thoughts.

I applaud all of you who are really thinking through this radiation decision. I was so much in the fog, I just followed doctors orders and I have regretted it. I had a stage 1. 1.6 tumor with clear margins and no nodes. I still do not understand why they recommended I do rads. Even with insurance, I had to pay about $20 grand because my treatments went over one year into another, equals paying 2 deductibles. I truly felt I was cured after the surgery, and I am now doing all I can to live a better, healthier lifestyle. I do not worry about the cancer coming back, but I do worry about the long term effects of rads. I just wish I had made a better educated decision. My only advice, is to follow your own instincts. We all know what our own inner voices are saying and we need to listen. Then, no matter what decisions we make, there is no second guessing and we can be at peace that we made the right ones.

Gosh, Rafaela, I can see why you are not racing out to have (more) radiation! Do you feel good about the communication among your oncologists (surg, rad, med)? and that your current rad onco has a good sense of the radiation you have undergone before? That's all I can offer at the moment. Except my best wishes -- and appreciation (awe?!) that you are here and posting.

Rafaela
Ditto what Rock said.
Wow, you are amazing.

Hi Guys....I just had a lumpectomy....Clean margins, and the last tiny bit of cancer that was left after the biopsy was taken out....I will be discussing my coming six weeks of radiation treatments with my BS in the mornig....
I decided on rads because the BS told me that there was a 20% chance of recurrence withouth it, and only 5% with it....I fell into the 20% of those whose calcs were malignant, so didn't like those odds...Hence the rads.
I want to do everything possible to rid myeslf of cancer, and assure myself that it's chance of returning is reduced as much as possible...Because of other medical issues I will not be taking Tamoxifen....So..This is my best shot.
No...I don't want to do the rads....six weeks of trekking to the hospital, trying to work part-time, possible SE's...But....I am determined to give myself the best possible chance at a full recovery...

Amazing? I don't know about that. I'm more like a weird statistic in Boston. Most people who had what I did when I was 29 typically only lived for 5 - 10 years. The specialists in Boston felt that the tumors I had in my should could have been a long term side effect of all the radiation I got when I was 29 - key words - could have been. No one lived long enough to be sure.
I'm actually wondering if this new cancer adventure could be possibly related.
More info will be revealed this week when I have the post op appt with the BS.

Sandy,
Was your DCIS left or right sided???
-
Rafaela,
What kind of cancer were you diagnosed with when you were 29??
-
MarieKelly - it was an undifferentiated carcinoma - no primary site found at the time. one day nothing - next day I looked in the mirror and said what the heck is that?
