Hormone therapy may confer more aggressive properties to prostate tumours
June 11, 2009
Hormone therapy is often given to patients with advanced prostate cancer. While it is true that the treatment prevents growth of the tumour, it also changes its properties. Some of these changes may result in the tumour becoming more aggressive and more liable to form metastases. This is one of the conclusion of a thesis presented at the Sahlgrenska Academy. Hormone therapy has serious side effects and is therefore used only when the tumour has grown too large to be treated in any other way, or when the tumour has spread and formed metastases. The hormone that is given causes the natural production of male sex hormone to fall, and the tumour stops growing. Pain also usually decreases.
"Our results suggest that the tumour properties change following hormone therapy such that the tumours at a later stage can continue to grow and spread in the body. For this reason, it is probably necessary to supplement the hormone therapy in order to compensate for these changes", says pharmacist Karin Jennbacken, author of the thesis.
The results show that patients who have been given hormone therapy have higher levels of the proteins that enable the cancer cells to move through the body and attach to other organs. One of these proteins is known as "N-cadherin", and this protein is present in higher levels in patients who have been given hormone therapy.
"We don't have any good treatment alternatives in cases where the tumour returns after hormone therapy, and this means that it is particularly important to study how such tumours are controlled and how they behave. The properties that we have identified may become targets for new anti-metastatic drugs in advanced prostate cancer", says Karin Jennbacken.
PROSTATE CANCER
Approximately 9,000 new cases of prostate cancer are diagnosed each year in Sweden, making it the most common of all cancer forms. Many of the tumours grow very slowly and give no symptoms, but prostate cancer can also display a more aggressive course, spreading metastases to lymph nodes, the skeleton and other locations. The complete prostate is often surgically removed if the cancer is diagnosed early. Other treatments available are radiation therapy and hormone therapy.

Study shows hormone replacement therapy decreases mortality in younger postmenopausal woman Hormone replacement therapy (HRT) to treat menopausal estrogen deficiency has been in widespread use for over 60 years. Several observational studies over the years showed that HRT use by younger postmenopausal women was associated with a significant reduction in total mortality; available evidence supported the routine use of HRT to increase longevity in postmenopausal women.
Hormone mix could cut breast cancer risk and treat symptoms of menopause The right combination of estrogen and a selective estrogen receptor modulator (SERM), which blocks the effects of estrogen in breast tissue, could relieve menopause symptoms and cut breast cancer risk.
Breast tenderness during hormone replacement therapy linked to elevated cancer risk Women who developed new-onset breast tenderness after starting estrogen plus progestin hormone replacement therapy were at significantly higher risk for developing breast cancer than women on the combination therapy who didn't experience such tenderness, according to a new UCLA study.
Women with breast cancer have low vitamin D levels Women with breast cancer should be given high doses of vitamin D because a majority of them are likely to have low levels of vitamin D, which could contribute to decreased bone mass and greater risk of fractures, according to scientists at the University of Rochester Medical Center.
Researchers believe hormone therapy should not be stopped prior to mammograms Researchers from Boston University School of Medicine (BUSM) are recommending that menopausal women on hormone therapy (HT) continue their treatment prior to having their annual mammogram screenings.
Prostate cancer patients on hormone therapy at increased risk for various heart diseases New research has found that hormone therapy used to treat men with advanced prostate cancer is associated with an increased chance of developing various heart problems. Some choices of therapy appear, however, to be less risky than others.
Long-term tamoxifen use increases risk of an aggressive, hard to treat type of second breast cancer While long-term tamoxifen use among breast cancer survivors decreases their risk of developing the most common, less aggressive type of second breast cancer, such use is associated with a more than four-fold increased risk of a more aggressive, difficult-to-treat type of cancer in the breast opposite, or contralateral, to the initial tumor.
Hormone therapy for prostate cancer patients with heart conditions linked to increased death risk Men with coronary artery disease-induced congestive heart failure or heart attack who receive hormone therapy before or along with radiation therapy for treatment of prostate cancer have an associated increased risk of death.
