  1. " In what seems to be a first, study researchers are saying that they might have uncovered a link between ADT and Alzheimer’s. Their study is small and preliminary and it does not prove a cause-and-effect relationship, but merely shows an association between ADT and Alzheimer’s disease." Click here to read more.

    Firmagon injection - minimising side effects

    One of the drugs used in androgen deprivation therapy is Firmagon (degarelix). Firmagon requires a monthly injection. There can be severe pain at the site of the injection (caused by bruising and rashes which can last for 3-4 days each month). This post has been updated with additional suggestions about how to miminise the pain from a Firmagon injection.

    Coming out of the closet

    Dr Richard Wassersug writes the Life on ADT Blog and is a co-author of the book Androgen Deprivation Therapy:An Essential Guide for Prostate Cancer. In 2007 he wrote an article in the New York Times announcing that he was a eunuch. Click on this link to read the article
  4. Depression resulting from Androgen Deprivation Therapy is a completely under-recognized phenomenon, according to a recent article. Click on this link to read the article. Beyond Blue 1300 22 4636 and Lifeline 13 11 14 provide support for depression.
  5. Luteinising hormone-releasing hormone agonists (LHRHa) or antagonists are used for Androgen Deprivation Therapy in men with advanced prostate cancer. These include Zoladex, Lucrin, Eligard and Firmagon. Oral estrogen (eg, diethylstilboestrol [DES]) was previously used for Androgen Deprivation Therapy before the development of LHRHa drugs. Oral estrogen ceased to be used for Androgen Deprivation Therapy because of cardiovascular toxicity (damage to the heart). The cardiovascular toxicity was caused by the way that oral estrogen was metabolised in the liver. If estrogen is administered intravenously, by injection into a muscle or transdermally (using patches on the skin), it is metabolised in a different way from oral estrogen. Scientists believe that administering estrogen in this way could avoid the cardiovascular toxicity that occurs with oral estrogen. They are conducting a large clinical trial (PATCH) in the United Kingdom to see whether this is correct. If it is correct, then estrogen might be a much cheaper method of Androgen Deprivation Therapy with less side effects than the very expensive LHRHa drugs. A study was conducted of some of the men participating in the PATCH trial to examine whether estrogen and LHRHa drugs had different effects on bone mineral density.

  6. The New Prostate Cancer Infolink reports Full data on ADT + chemotherapy from the STAMPEDE trial now published The report has links to the full text of articles in the Lancet regarding this research. "For men with metastatic prostate cancer starting [androgen deprivation] therapy for the first time, we found strong evidence to support the addition of docetaxel to androgen deprivation therapy as the new standard of care, and this combination should be offered to men who are fit to receive chemotherapy. " There is no sufficient evidence yet to recommend docetaxel plus androgen deprivation therapy for hormone-naive men men diagnosed with micrometastatic prostate cancer (cancer in the lymph nodes but not yet metastasised to the bone - M0)

    ADT negatively affects mood

    Researchers asked prostate cancer patients to fill in an online questionnaire on their mood in relation to the prostate cancer treatments they had received. Their results showed that, compared to patients not on ADT, ADT does indeed negatively affect the mood of men, most notably increasing their sense of fatigue and decreasing their sense of vigor. The authors also asked partners of patients to rate the patients’ moods. The partners reported similar declines in the patient’s mood that the patients reported, but to a greater degree than the patients themselves. Often our partners know us better than we know ourselves. Van Dam D, Wassersug RJ, Hamilton LD. Androgen deprivation therapy’s impact on the mood of prostate cancer patients as perceived by patients and the partners of patients.

  9. A retrospective study of nearly 17,000 patients has suggested that androgen-deprivation therapy (ADT) is associated with an increased risk for the future development of Alzheimer's disease in men with prostate cancer,. Click here to read a report in the New Prostate Cancer Infolink about the study. Researchers can’t prove a direct cause-and-effect link between ADT and Alzheimer’s in an observational study like this. Some other unknown variable might be influencing the results........ Given that it’s a first-time association in a retrospective analysis, this study helps inform future research but it’s not appropriate at this point to make treatment decisions off of it......... If your doctor has put you on this medication for your prostate cancer treatment, you should continue it. Consult with your physician, but don’t stop taking your medication based on a study like this....
  10. A good video by the Prostate Cancer Canada Network Calgary. Psychologists from the Tom Baker Cancer Centre in Calgary Canada, Lauren M. Walker and John W. Robinson, share a talk the context of when Androgen Deprivation Therapy, or ADT, is used for treatment. They also talk about the studies and work they've done on the treatment, the side effects and ways to deal with them.
  11. In today's teleconference it was suggested that Megace might be useful to reduce hot flushes. I notice that Chuck Maack recently referred in a US forum to a warning by top Medical Oncologist Stephen Strum against men on androgen deprivation therapy using Megace for hot flushes. Strum warns: "I am not a user of Megace in this setting since it is metabolized to DHEA and then to androstenedione and then to testosterone. When the PSA is in good control and the testosterone is low, I use Depo Provera intramuscular injection 400mg ONCE and that usually eliminates hot flashes forever. The emphasis on "usually" added since there are rare cases wherein the hot flashes are not reduced/eliminated. Therefore, a 400mg Depo Provera intramuscular injection just once would be what I would have done were I experiencing hot flashes. Make sure the prescribing/administering physician is providing Depo Provera and at the recommended dose, and not Provera. Though both are Medroxyprogesterone, the difference is that Depo Provera is an addition of acetate. There are physicians not familiar with that difference who prescribe Provera when the requirement is, specifically, Depo Provera. HOWEVER, IMPORTANT TO NOTE: Depo Provera has also been known to cause gastrointestinal bleeding and a low HCT percentage can also be attributed to loss of blood. If you are experiencing fatigue and shortness of breath subsequent to Depo Provera, you may be experiencing a blood loss with this gastrointestinal bleeding and don't know it. Be sure your physician keeps an eye on red blood counts (RBC) as well as HGB and HCT levels". You should not start any treatment for hot flushes unless you have first discussed it with your doctor.

    ADT affects the brain

    Cognitive impairment can occur in cancer patients who are treated with a variety of therapies, including radiation therapy, hormone therapy, and chemotherapy. After chemotherapy treatment it is commonly called "chemo brain." Signs of cognitive impairment include forgetfulness, inability to concentrate, problems recalling information, trouble multi-tasking and becoming slower at processing information. The number of people who experience cognitive problems following cancer therapy is broad, with an estimated range of 15 to 70 percent. There have been several studies analyzing this side effect in breast cancer patients, but few have investigated cognitive impairment following androgen deprivation therapy (ADT) for men being treated prostate cancer. A new Moffitt Cancer Center study indicated that men who are on ADT have greater odds of experiencing impaired cognitive function. In this study, researchers used formal tests to compare the cognitive ability of 58 prostate cancer patients on ADT to 84 prostate cancer patients not on ADT, and to 88 men without cancer. The researchers also reported for the first time a possible genetic link among those individuals who experience cognitive impairment whilst on ADT. They found that patients who have a particular version of a gene called GNB3 were 14 times more likely to suffer from cognitive problems on ADT. The researchers suggested that doctors: before starting ADT, should discuss the risk of changes in cognitive functioning with their patients; and after starting ADT, should also ask their patients if they suffered cognitive impairment with a view to referring them for assessment and treatment as needed. I wrote to one of the researchers and asked what treatment was available for prostate cancer patients on ADT who suffered cognitive impairment as a side effect. This was his reply: “Unfortunately little research has been done on ways to improve cancer treatment-related cognitive impairment. But some recent studies have suggested that "brain training" may improve cognitive function...and [there is] some preliminary evidence suggesting benefits to cancer survivors who had cognitive impairment. There are also medications that could be helpful, such as stimulants (e.g., methylphenidate, modafinil). It is also recommended that other issues that could contribute to cognitive decline be adequately addressed. For example, depression or sleep problems could easily worsen cognitive functioning and are usually treatable. Exercise has also been shown to be very important for cognitive function. I would recommend first addressing the issue with your oncologist or perhaps requesting a referral to a neuropsychologist or another provider who may be able to make recommendations tailored to your situation.” Brian D.
