Topical Tamoxifen anyone?

Any info at all about Topical use of tamoxifen on the breasts? I have found on the web that there are studies on its use for DCIS patients as an alternative to help get more women who have stage 0 to use a hormone blocker.

I would love to hear if it is and where it might be available. I'm thinking of it as an option to those who may have later stage breast cancer and have decided to quit the oral tamoxifen due to side effects. I would think anyone who decides to quit should have access to the topical tamoxifen

    My wife is in the same situation. Though her tumor is invasive there is no evidence by palpitation that lymph nodes are affected. Tamoxifen oral is being used to contain the tumor and it has softened and reduced the tumor. Her oncologist will not pursue the topical Tamoxifen as it may not catch any cancer cells that might be in blood stream or lymphatic system. As a cancer patient my wife who is 77 and not a candidate for surgery due to overall health is willing to take that risk. I emailed Dr. Khan (skhan@nmh.org) who was involved in the study but he took the same position. To me as a logical thinker such a position defies logic. I think we should pursue this until we find someone who will help us. It may be a money trail problem. I considered trying to make a topical by dissolving a tablet in dmso but I found that the topical has been through some process of metabolization. I am wondering if my congressman could find some help through NIH or other avenues.

    Eddie t-thanks for your response. I also considered trying to make my own topical tamoxifen. Though you are right that the formula would be risky and perhaps not as easily metabolized..

    I am currently taking 20 mg tamoxifen per day. For about 2 weeks now. I am just starting to get some side effects. It is very frustrating to be on the cusp of better treatments that may take years to meet approval.

    I had cancer in my lymph nodes and I am worried about mets throughout my body...but I also am worried about tamoxifen or AIs making my life less than optimal. I really think if a person was fed up and about to quit (30 percent of women do quit) those women should have access to an alternative.

    I'm so happy to hear the tamoxifen is helping your wife in a visible manner. That is always got to have a 'worth it' feeling.

    Thanks

    I asked my MO about topical Tam on my 6 month follow up visit. I quit oral 20mg after 2.5 yrs. She said she was good with me dis-continuing, but had never prescribed the topical. She was concerned about the local vs systemic benefits of the topical form and that it may not be effective against mets. She assured me that a local recurrence can be "taken care of" but mets are the main concern. It would be nice to have an alternative for sure. Right now, I am considering myself done with TX and pray that I don't ever have to deal with it again. Trying to change my lifestyle to eat a healthier diet, staying away from parabens as much as possible, organics when possible, cut back on alcohol intake, taking baby aspirin daily, turmeric/curcumin, exercise more and be HAPPY!:)

    keep the faith- 2.5 years that's good. I've read even two years can have a long term benefit.

    I am already getting some wierd side effects but I can live with them so far. I want to make it at least two years and of course I'm going to try for the whole ten.

    You seem like a perfect candidate for topical tamoxifen! since negative nodes! I think you should keep trying for the topical. Seek someone who will go the extra mile for you.

    And of course keep in touch if you find some. I'm keeping with the oral for as along as I can stand it because I had large node involvement.

    I do want to know more about topical options should I feel tamoxifen is ruining my life. Options even if risky are not offered enough.

    Sorry you had to quit.

    Hugs e

    I sent the following message to the NCI;

    My wife age 77 has invasive ductal carcinoma but is considered too high a high risk for surgery. The medical oncologist is controlling the carcinoma with oral tamoxifen. In fact the carcinoma has reduced in size from 3.5 cm to 2.5 cm and has softened somewhat within a few months of therapy. I asked the oncologist to look into availability of tamoxifen gel but she dismissed it as experimental and primarily for prevention of recurrence. My wife is experiencing some side effects with the oral tamoxifen and since her overall health is quite fragile I would like her to be able to try the gel. One argument against it would be that if cancer cells are in the lymph nodes or beyond the topical gel wouldn't reach them, however lymph node palpitation is negative.

    As an engineer my training has been in logical thought process. My thoughts are that after a time on oral tamoxifen most met cells (if any) would have been starved and that tamoxifen gel would work on the local level to continue tumor reduction and reduce the chance of met cells escaping.

    She is not able to travel to a distant cancer center for trials or treatment but her oncologist has clinical trial experience and could cooperate with a trial group if she had the interest. To me it just isn't logical not to be able to try something that can offer some hope for a better quality of life.

    I would greatly appreciate it if you could provide any leads that might help us. We are located near Asheville and Hendersonville, NC.

    Eddie-t- that is a great step in the right direction. I'm happy to hear that your wife is responding to the tamoxifen.

    Let us know if you get anwhere with your inquiry.

    Thanks

    Hang in there

    No response yet but did receive an acknowledgement. I read up on plans for clinical trials and they won't help us as they require double blind studies and we just seek life with a bit more quality. If I get a response I hope to open a dialog after all they already know the topical won't kill us so why wouldn't info regarding quality of life improvement be of mutual benefit?

    hi Eddie, thanks for the update. Pretty frustrating to say the least. Maybe there is a way to get it form overseas..

    Keep in touch

    I did receive a response and am wondering how I might proceed since the paperwork requirements might turn off her oncologist. Here's the response (I had to remove links in order to post, regs ...regs ... get in the way of people with a need):

    Cancer.gov Inquiry - Tamoxifen Gel Availability

    Response By Email (NCI Agent) (08/15/2017 09:40 AM)

    Thank you for your e-mail to the National Cancer Institute (NCI) regarding the use of tamoxifen gel (4-Hydroxy-Tamoxifen/afimoxifene) by your wife who has breast cancer. We are sorry to learn about your wife's diagnosis and understand you are seeking treatment with the least side effects for her.

    Afimoxifene is a form of the drug tamoxifen that is made by the body after taking tamoxifen. It can also be made in the laboratory, and may help decrease breast density. A topical form of 4-hydroxytamoxifen is being studied in breast cancer screening.

    A search of the ClinicalTrials.gov database for studies investigating 4-Hydroxy-Tamoxifen/afimoxifene and breast cancer did not yield any trials for which your wife may be eligible.

    A search of the medical literature did yield studies, but they were mainly for chemoprevention and/or ductal carcinoma in situ (DCIS), a noninvasive condition in which abnormal cells are found in the lining of the breast duct. A list of journal articles concerning "transdermal tamoxifen" can be found at ******.

    The most common way that patients receive an investigational drug is through a clinical trial. Less common ways that patients can receive investigational drugs include mechanisms such as an expanded access protocol or a special or compassionate exception. The sponsor must agree to provide the drug for this use.

    Investigational drugs given under these mechanisms must meet the following criteria:

    • There must be substantial clinical evidence that the drug may benefit persons with particular types of cancer.
    • The drug must be able to be given safely outside a clinical trial.
    • The drug must be in sufficient supply for ongoing and planned clinical trials.

    You will need to work with your wife's doctors if you decide to seek access to 4-Hydroxy-Tamoxifen/afimoxifene through expanded access or compassionate exception. For more information about these two mechanisms, please visit *****

    Please be aware that the information provided does not constitute medical or legal advice.

    Thank you for writing. We wish your wife the best.

    Keepthefaith-

    We are approaching the hormonal therapy in the same way. I have also changed my diet (mostly vegetarian, but I do occasionally eat chicken or fish), I am now exercising an hour a day five times a week, and I am taking the baby aspirin. I would use the topical Tamoxifin, but I am unwilling to trade quality of life for a 2.5% benefit. Interestingly, you also have the exact same diagnosis that I have except mine was on the left side.

    I am also looking the the Tamoxifen gel. The study was done in 2014 and I thought it should have been out on the market by now. Does anyone have any information where we can get this?

    I just checked around and could not find any reference after 2014. Too bad. It would be even better if there were a Femara Gel.

    Here are a list of previous and current studies and research that I could find about the topical Tamoxifen, sometimes also called 4-OHT, Afimoxifene, 4-Hydroxytamoxifen (4-hT, OHTAM).

    I've bookmarked them and will be asking my MO about them, since I am still on the fence about oral Tamoxifen due to all my previous health complexities.


    Hope this is helpful. :)
