Question

Dear OncoLink "Ask The Experts,"
Can you tell me please if it is unusual for radiation to the rectal/lower abdomen area to cause vaginal stenosis? 

Answer

Richard Whittington, MD, Associate Professor of Radiation Oncology at the University of Pennsylvania School of Medicine, responds:

Most women getting radiation to the pelvis develop vaginal drying as a side effect of the radiation treatment. This problem is common and managed by the radiation oncologist. It can potentially lead to vaginal stenosis in some patients (stricture of the vagina). At the end of radiation to the pelvic area, woman are typically given a vaginal dilator that is inserted into the vagina for a few minutes daily to separate the tissue surfaces. This is done to prevent scarring that can contribute to vaginal stenosis. This may be done indefinitely. Also, in younger women (under 50) we usually recommend hormonal replacement, except in endometrial cancer or breast cancer patients and this will reduce the severity of the problem. A woman who is sexually active and has intercourse at least 3 times/week can usually avoid using the dilator.

Addition of radiation therapy to rectal, prostate cancer treatments studied

Nov 1, 2010 - Radiation therapy appears to reduce recurrence rates when added to surgical treatment of rectal cancer and to increase survival when added to medical management of prostate cancer, and a highly targeted radiation approach may reduce gastrointestinal complications associated with prostate cancer treatment, according to three studies to be presented at the annual meeting of the American Society for Radiation Oncology, held from Oct. 31 to Nov. 4 in San Diego.
