Smoking, Radiation And Prostate Cancer
Smoking has been found to contribute to poorer outcomes for people treated for a number of kinds of cancer and now, scientists at Fox Chase Cancer Center have associated smoking and acute side-effects following radiation treatment for prostate cancer. The study was presented today at the 48th Annual Meeting of the American Society for Therapeutic Radiology and Oncology in Philadelphia.
Smoking is linked to an increased risk of radiation-related side effects in cancers of the head and neck, cervix, lung and breast. For this study, scientists analyzed the impact of smoking on gastrointestinal (GI) and genitourinary (GU) side effects for 1,194 prostate cancer patients treated at Fox Chase Cancer Center with 3D conformal radiation treatment between 1991 and 2001. Smoking information collected previous to therapy included status as a current smoker, ex-smoker or non-smoker. Patients treated with androgen deprivation previous to or during therapy were excluded.
"Our patients who smoked during therapy reported having more acute gastrointestinal side-effects such as diarrhea," said Niraj Pahlajani, M.D., lead author on the study and a resident in the radiation oncology department at Fox Chase.
"Fortunately, smoking didn't appear to impact long-term GI side effects or genitourinary side-effects. These results underscore the importance of smoking cessation previous to radiation treatment".
