microinvasion discounted?

Can anyone figure this out for me?

I was reading my initial biopsy report and it said 'microinvasion is seen but discounted'.  No mention of why it was discounted or how much they saw.  If true microinvasion is molecularly different than DCIS how could it be discounted? Or does it mean that some DCIS cells were outside of the duct/lobules,  but there were no molecular changes?

Any thoughts are greatly appreciated! Thanks

    Absolutely, true microinvasion is biologically different than just displaced DCIS cells.  That was a big question for me, as I had what I think is the same thing.  My core biopsy pathology said that a microinvasion was suspected but ruled out.  It went on to say that the "atypical focus appears to have been traumatically introduced into the tissue by the biopsy".  Meaning that there were cells outside the duct, but they thought they were displaced (by the biopsy needle) DCIS cells.  When I sent all my pathology (biopsy and lumectomy) to Dr. Michael Lagios the, private pathologist who is the 30-yr DCIS and DCIS-MI expert, he said they were wrong to rule out (or "discount") the possible microinvasion in the core biopsy.  He said it had indeed been a micro, and explained why, molecularly.  Thankfully, it did not change the bottom line bout my treatment/prognosis.  Stil. it was upsetting, all the things he saw that my HMO did not.

    clarrn,

    I think you need to ask your breast surgeon why the pathology report says that the microinvasion is "discounted".  

    I've seen biopsy reports that say "suspicious for microinvasion" or that there is a "possibility of a microinvasion" or "microinvasion can't be ruled out" - this is what is often said when some cancer cells are found outside of the duct but they aren't certain if the cells were misplaced by the needle or whether it's a real microinvasion.  Often with a needle biopsy they don't do the full biological analysis to determine if those cells are displaced DCIS cells or a true microinvasion - they wait until the surgery to see if any more invasive cells are found.  But they certainly shouldn't completely discount a microinvasion (or possible microinvasion) at this point - it's more appropriate to note the possibility. 

    What else did the report say, in terms of the DCIS pathology?  And have you had your surgery yet?

    Bessie - it says Diagnosis -high grade mammary carcinoma in situ with extensive comedo necrosis, negative for invasive carcinoma in this limited sample.  

    Then in the microscopic description it says 'Good quality core biopsy sample are positive for mammary carcinoma in situ, nuclear grade 3/3.  The tumor exhits a solid architecture,  prominently cancerizes terminal ducts/lobular units and exhibits zonal comedo necrosis with prominent  super-imposed dystrophic calcifications.   A high grade pleomorphic lobular subtype must be considered.  E cadherin evaluation pending. (I was verbally told it came back as negative for the subtype).  This limited core biopsy sample is examined in levels and employing myoepithelial immunostains. Microinvasion is seen but discounted.   This high grade lesion might be at increased risk for microinvasion,  for comprehensive assessment in the excision specimen. '

    I have my PS consult coming up on the 29th and then likely 6 to 8 weeks before they have enough OR time as they are planning immediate DIEP recon if no surprises in the sentinel node or chest wall.  Of course with all this time I am trying not to worry.  The likelihood of spread in that time is minimal.  Also my initial biopsy and report was done in one city and my surgical oncologist is in another and she had my biopsy redone (4 more cores sent) last Tuesday,  still waiting for those results and am hoping that maybe my surgery will get bumped up!

    Thanks percy4 and bessie for your quick responses!

    ...and forgive me, but i thought dcis by its nature would be only testing of sentinal node. i am only concerned because if you do mastectomy, they will take even more nodes from her, wont they beesie? anyway i thought i had read that lately. just worried cause i would hate to see her get lymphedema, from having dcis!

    Kathec -The DCIS takes up my entire breast on mammogram and the solid tumor has now grown to take up 2/3 of my breast so there is no way to do anything less than mastectomy.   Due to the high grade andthe fact that they are doing a mastectomy they do the SNB because if invasion is seen after excision they  would have missed the SNB opportunity.

    They will not do axilla node dissection unless my SNB comes back with surprises.   And at 30 years old I'm done with surprises for now ;)

    Sorry my above post may be confusing,  I meant that the non palpable part of my DCIS lit up my whole breast on mammography and the palpable part has increased to 2/3.

    Hi clarrn:  I just wrote a lengthy response and it disappeared! Trying again.  I too had to have a mx due to a large dcis and a small breast.  The mx went extremely well (I did not have reconstruction) and I hope yours does too.  It is five weeks post mx and I am pretty much fully functional and back to myself (minus one breast!)  You have already heard from the expert on micro-invasion.  I am no expert in that topic, but am gaining expertise in dealing with surprises along the way.  I had a positive margin so have to consider radiation now.  Your situation is very hopeful, but surprises happen.  They usually are not extreme, but they can send you spiraling again.  Try to focus on your surgery and your recovery.  One step at a time.  Your diagnosis is not final until the pathology following your surgery.  If you face a surprise, all the ladies here are amazing to answer new questions and to provide support along the way.  I have been shocked by all the information and treatment decisions to be made and how difficult these decisions are.  Thinking of you and all the best. (((((hugs)))))

    Hi everyone. I'm not only new to BC but also...this is my first time ever doing anything with online discussions. I am lost, so I figured I try one of you for help on which way to go with this discussion thing because none of the categories on the forum list matched me exactly. I had a suspicious mammo (BIRAD 4) on Dec. 9. Took 2 weeks to get to see a surgeon that my gynecologist referred me to. Then it took another 2 weeks to have a stereotactic core biopsy...which left me with a hematoma. The biopsy report says "Grade 2 microinvasive ductal carcinoma...Nuclear grade 2-3 duct carcinoma in situ, solid and bribriform type, focal necrosis and calcification deposits." ER and PR both say positive but HER-2-neu says "requested". When I met with the surgeon she said requested meant there wasn't enough tissue to test the HER-2. I also met with my Oncologist (which I've had for 3 years due to having appendiceal cancer 3 yrs ago -had appendectomy 1 week and then on to right hemi-colectomy a week later). Oncologist talked lumpectomy with radiation and hormone therapy but that mastectomy would be another choice. MY MAIN CONFUSION IS ...Based on my history of other cancers I feel maybe I should have bilateral mastectomy. I don't really want to go all that invasive with surgery unless it's in my lymph nodes. But how am I suppose to choose which surgery when you don't find out if it's in any lymph nodes till surgery? I also don't know what the HER2 is and haven't had genetic testing either. I had an MRI a little over a week ago...results are confusing as to what is what and sizes of enhancements because of the hematoma, but did say my other breast is clear and also "no morphologically abnormal axillary lymph nodes are identified"...how reliable is an MRI regarding lymph nodes? I have a friend in SC who was actually assigned a multidisciplinary team to help her with everything....no one here has told me about anything like that. I separately have an oncologist, breast surgeon, upcoming appointment with a plastic surgeon on the 31st and no appointment with a radiologist yet. I'm now worried that because mine is "microinvasive" (and became that in 1 year) which I read at one of the cancer sites is really just a small version of "invasive" and almost 2 months have gone by since mammo...worried that my cancer has already had time to spread to wherever, even lymph nodes. Today I just happen to be exceptionally upset over all this and all the time everything is taking and that I'm forced to make some surgery decision when I don't know results of some important testing. Any help here regarding which direction to go in would be soooo appreciated.  Thank you in advance :-)

    Sam, I think I would want genetic counseling before you make your decisions based on the other cancer. It could have bearing, but it also might not. 

    I was surprised that the type of ovarian cancer I had doesn't really up my breast cancer risk very much, but there are genetic syndromes that can cause both colon or intestinal cancers and breast cancer.

    I can only repeat that though it is standard to do a sentinal node biopsy in the case of a microinvasion, my MO says she has never seen a positive result in the nodes with a micro.  And, again, I'm presuming that when a micro is discovered, it almost certainly has had to already have been there for SOME period of time.  As to the lumpectomy/rads as opposed to the mx, I will have to defer to the more experienced advice you will get here from someone who knows more than I do.  Best of luck. - P.

    Hi samrodun,

    So sorry you are going through this.  I am on a similar time frame with all the appointments too and definitely understand your worries.   Have you read Beesie's layman's guide to DCIS? I found it really helpful.  The wait time is unlikely to make a difference in our treatment or survival rates, so I hold onto that.  Unfortunately I won't have my geneticist appointment until months after my surgery either and we don't see the radiologist or oncologist until after surgery.   So it does sometimes feel overwhelming.  I have chosen bilateral mastectomy but its an extremely personal decision.   If you have the option for lumpectomy and take it you do have the option of mastectomy later, but not vise versa.  I made lots of lists and pondered all the scenarios I could think of and how I would handle each one with my personality and life.  Good luck with your decision but don't make it based on what we say on here.  The advice can be helpful but you are unique!   Hugs and hope to you!  Feel free to pm me if you need to vent.

    For the notications you have to change a setting in your profile.

    Update: They took more biopsy samples on jan 21, results today show at least one area of 9mm of invasive ductal carcinoma.  Guess they shouldn't have discounted it :(

    As well this 9 mm invasion was found in the first biopsy tract( biopsies done dec 13 and jan 21).  Three pathologists looked at it to confirm it wasn't displaced DCIS and I was shocked that I developed actual invasion in only 5 weeks.  Anyone else have something grow that fast?

    clarrn, you're right, they shouldn't have discounted the microinvasion!

    It is interesting that the invasive cancer has been found in the biopsy tract, but I wouldn't conclude that this means that the invasive cancer has developed since your biopsy.  Thinking about it, I'd actually conclude the opposite.  Your biopsy did pull up that one microinvasion which means that the needle did go down into the area with IDC.  The reason that it's often recommended that biopsy tracts be removed is because of the risk of contamination, the risk that the needle might drop some cells into the tract or leave behind some cells on the way out of the breast.  So that's what I would guess happened here.  This invasive cancer was probably there along, but wasn't pulled into the core of the needle.  Instead, these cells might have been next to the needle and the side of the needle might have pulled some of those invasive cells into the tract. Or perhaps those existing invasive cells found their way from their location right at the opening of the needle tract and moved into the small gap left by the needle, filling the tract. That seems a lot more likely than the needle contaminating the tract with DCIS cells, and then those DCIS cells evolved to become invasive over just 5 weeks. 

    With 9mm of invasive cancer, what will be most important now in determining your treatment plan will be the HER2 status of the invasive cancer.  And if you are HER2- and node negative, I'm guessing that your doctors will send your invasive tissue to get an Oncotype score, and that will be important too.  Hoping for good results on all of that!

    Thanks Beesie,

     I think you are right, that would make more sense, and gives me some peace of mind although we still dont know time frame for DCIS progression.  I wonder if they sent the sample for Her2 testing as there was no mention of it.  I will look for it on the report when I get it and make sure it is done.  The oncotype test is not funded here in my province in Canada even though we have been lobbying for it since 2011.  Do you think I should pay the 4175 US to have it done? I am a bit nervous about under treatment because my surgical oncologist said still no chemo/rads/tamoxifen needed bc I am having a BMX.  I know final determination of that will depend on surgical pathology, but I worry that she is not even concerned with the possibility of it.

    If you are HER2+, then with a 9mm invasive tumor, you will need both Herceptin and chemo.  Generally the line in the sand for HER2+ is a 5mm tumor.  And if that's the case, then you won't need the Oncotype.  Same thing if you are node positive, which hopefully you won't be.  So whether you might benefit from the Oncotype really depends on those two things - it's if you are HER2- and node-negative, that the Oncotype becomes more important to the diagnosis.  

    By the way, having a BMX doesn't change whether you would need chemo (and Herceptin) or not.  Those are systemic treatments that are given to address the risk that some cancer cells might have already moved beyond the breast, so whatever surgery you have to your breasts doesn't matter.  Rads is different; usually rads isn't required after a MX unless the area of cancer was very large, or there are several positive nodes, or the margins were very close, particularly at the chest wall. 

    I am surprised with a 9mm invasive tumor that you are being told "no" to Tamoxifen.  For someone with DCIS or only a microinvasion who's had a BMX, Tamoxifen usually isn't recommended.  But with an invasive tumor of 9mm, normally Tamoxifen would be prescribed, whatever the surgery. Here again, the role of Tamoxifen is to address the risk of distant recurrence, so whether you've had a lumpectomy or MX shouldn't matter. 

    What province are you in?

    According to the Alberta treatment guidelines, both hormone therapy and chemo/Herceptin should be discussed as options with patients who have ER+, HER2+ node negative cancers that are 5mm in size or greater.   So without knowing your HER2 status, and knowing that you are ER+, it's odd that you were told no chemo and no Tamoxifen.  But then it was your surgeon who told you this, and really the surgeon's role is surgery; it's the medical oncologist who will have the discussions with you about other treatments.  Still, your surgeon should have either have said nothing and referred you to the MO, or she should have explained that your pathology will determine what treatments may be recommended.

    A surgical oncologist is still only a surgeon, just one who specializes in cancer surgery rather than general surgery.  A surgical oncologist will of course have familiarity with other cancer treatments (beyond surgery) but that's not their area of expertise nor it is usually their role to advise on or administer these other treatments.  A medical oncologist (often referred to as just an "oncologist") is the doctor who specializes in cancer itself and who is responsible for the overall treatment plan for a cancer patient.

    This is from a Canadian website:  "In the context of the
    multidisciplinary breast cancer treatment team, the oncologist is the quarterback.
    The oncologist is the one who typically requests additional imaging and biopsy/pathology
    studies in order to 'stage' the breast cancer. The oncologist is also the
    one who ultimately decides on the appropriate course of treatment, after consultations
    with the surgeon, the radiologist, the radiation oncologist, and the pathologist.
    An oncologist, or more specifically a 'medical oncologist' is also the one
    who determines and administers chemotherapy.
    " http://www.breast-cancer.ca/treatment/oncologist-hemato-treatment-breast-cancer.htm

    And from the U.S. National Cancer Institute:  "Medical Oncologist   A doctor who specializes in diagnosing and treating cancer using
    chemotherapy, hormonal therapy, biological therapy, and targeted
    therapy. A medical oncologist often is the main health care provider for
    someone who has cancer. A medical oncologist also gives supportive care
    and may coordinate treatment given by other specialists.
    "

    So yes, you definitely should be referred to a medical oncologist and ultimately it will be the medical oncologist, not the surgical oncologist, who should discuss with you any other treatments that might be advisable to reduce your risk of recurrence.  Should you choose to have any other treatments, it's the medical oncologist who will set up the treatment plan and monitor your progress.  

    With early stage breast cancer, often we don't see a medical oncologist until after surgery however for women who have more advanced cancers, it's very important to see the MO early on, before surgery.  Even for early-stagers, if you are uncertain about what you want to do or what may be ahead, seeing a MO before surgery can be helpful. An MO would certainly be able to explain why the type of surgery (lumpectomy vs. MX) won't impact whether or not you need chemo or Herceptin, and would be able to talk about why Tamoxifen might be advisable for you even after a BMX (again, this would be different for someone who has pure DCIS). 

    Hopefully you are HER2- and node-negative, in which case Herceptin won't come into the discussion (it's only for those who have invasive cancer that is HER2+) and chemo is much less likely to be considered.   If that's the case, however, since you would not be getting any treatments to address and reduce the risk of distant recurrence (a low risk with a 9mm tumor, but a risk nonetheless), it's more likely that you would be advised to give Tamoxifen a try.

    So frustrated! My nurse navigator told me they didnt send the sample for Her2.  She said they only send from the mastectomy samples, not from the core biopsy.   This sounds weird to me.  And what if they dont find any more invasion that large?  I guess now I am just worried that they might miss a positive Her2 and undertreat me.  I am finding it harder and harder to be patient, and harder to trust the whole system.  Also frustrated that I dont see an oncologist until after the mastectomy.  I feel so alone, and can't wait for my parents to get here next week!  Retail therapy tomorrow...

    It's quite common to not get the HER2 results from a biopsy and only to get them after surgery.  Type of cancer, ER, PR and grade usually comes from the biopsy; HER2 status and Oncotype scores (if it's determined that an Oncotype test will be beneficial) usually comes from the surgery.  

    If no more invasive cancer is found during the MX, the biopsy tissue should still be available and can be sent out then. 

    If you feel that you are not in a position to be confident about your surgery choice (and the possible implications of this choice) without talking to a medical oncologist, I'd suggest that you strongly request that the appointment be made now, so that you can talk to an MO before surgery.   But if the discussion won't impact your surgery decisions, then it really doesn't matter.  That's why early-stagers often don't see a MO until after surgery.

    To the rescue again Beesie, thanks! 

    I guess I was confused.  They told me with the first biopsy that Her2 was sent for invasive cancer routinely,  so that's why I was expecting it.  Although that was in Edmonton and the second one was in Calgary so it could just be a regional difference in the health care system. Oncotype is not funded in Alberta yet, so I will not know the recommendations from that.  I feel confident in my surgical choice and don't need an oncologist for that, but would like to see one to see what the chances of chemo being recommended right now are (even with the limited knowledge we have now).  If they are high I won't pay $4200 to have the oncotype test sent, but with my surgical oncologist saying that I won't need even tamoxifen,  I still worry about being under treated, and might send it for the peace of mind.

    With an invasive tumor that is known to be 9mm in size (at this point in time, prior to additional surgery), the oncologist won't be able to provide an assessment on chemo without knowing the HER2 status and the nodal status.  You just don't have enough information yet for an oncologist to make an assessment that has any reliability.

    HER2+ cancers usually get chemo (and Herceptin) even if they are only 5mm in size.  

    HER2- cancers (if they are ER+/PR+, as your cancer is) often don't require chemo even if they are as large as 2cm in size (or possibly even larger) if the patient is node negative.  But this is the situation where the Oncotype would be very helpful with the decision.

    Hi Clarrn and Beesie. As you probably know, I've only been on here a couple of times and am still lost as to how to get to information about my personal concerns. I appreciate your previous response, Clarrn, and I'm sorry I haven't been able to get back here for some time now. I'm also very interested in your opinions Beesie because after reading some of your posts, you sound like a nurse or at least VERY familiar with breast cancer issues.

    I finally opted to have right skin-sparing mastectomy with delayed reconstruction instead of lumpectomy, surgery was Feb. 20. As it turns out, I guess I made the right decision considering the surgery pathology report....my oncologist even agreed although she first recommended lumpectomy. I'm having 1 complication -- large 2" seroma on my upper chest right where the armpit starts and right where any bra strap or tank top would hit. Surgeon won't even consider draining it for at least another 4 weeks when she'll look at it then, and also saying it could resolve on it's own but would take quite a while. She said she also wouldn't write a script for a bra or prosthesis until atleast then, saying she'd prefer I didn't attempt to wear a bra yet. Seroma is quite sore and more of a nuisance than a worry.

    My core biopsy report diagnosis was DCIS with microinvasion. My surgical report says the DCIS area spanned 4-5cm area "although largest focus on the blocks measures 1.9cm". Taken were 2 sentinel and 1 axillary nodes, all negative. And the DCIS area was at least 1cm from the closest posterior margin. Stage is T1a N0. It also says in the surgical report "ER, PR and HER2 performed on previous biopsy"...which isn't correct because the biopsy pathology report did say ER+ and PR+ but after HER2 it said "requested"....I think I mentioned previously that my oncologist said that meant there wasn't enough area taken at biopsy for HER2 testing.  The surgical report says for Size of Tumor: "Microinvasive foci (see S14-409), whatever that is, and for Tumor Focality it says "Multifocal".  So, this leaves me not knowing much at all about how many ducts were involved or the extent of the microinvasion. And my oncologist while we were looking over this report just quickly brushed by the HER2 comment like it wasn't important.....I thought I had read previously in researching that HER2 is very important insofar as type of treatment???  Oncologist is highly recommending hormone therapy for 5 years explaining, if I understood her correctly, that even though my lymph nodes were negative that the microinvasion part of my diagnosis means that the cancer could, or already could have, spread through blood vessels in the breast tissue...so I was first ecstatic about negative nodes and the clear margins, but am now upset over the thought that I might actually have microscopic cancer cells traveling in my bloodstream.  

    I'm trying to decide between Tamoxifen and an Aromatase Inhibitor, looking at all the side effects. Just because I said that having stiff and aching joints as a side effect of an AI might continuously keep cancer on my mind, my oncologist rushed to say, "ok, I'll call in the Tamoxifen to your pharmacy" (treatment was very quickly discussed at end of appointment with her looking at her watch, and she said I could wait a couple weeks to start it). Now I'm wondering if an AI might be safer for me because of one of the side effects of the TAM being uterine cancer....and considering my prior problems--ruptured ovarian cyst at age 21, cervical dysplasia at about 30ys old, appendicealand colon cancer 3 years ago, and Barrets esophagus.

    I very much welcome and would greatly appreciate any comments and advice.

    Love and best wishes to all :-)

    Sam
