Abstract
INTRODUCTION: Radiotherapy or radical hysterectomy with salpingo-oophorectomy (SOE) as treatment for uterine cervical cancer causes estrogen deprivation in premenopausal women. The effects on androgen production have rarely been examined but could be relevant for survivors of cervical cancer because insufficiency has been associated with low sexual function. AIM: To investigate the effects of pelvic radiotherapy, hysterectomy with SOE, or surgery without SOE on androgen levels and to explore potential associations with sexual function. METHODS: Patients with cervical cancer (N = 60) were prospectively examined through blood sampling and questionnaires before and 1 year after treatments. MAIN OUTCOME MEASURES: Serum testosterone (measured by liquid chromatography and tandem mass spectrometry), sex hormone-binding globulin, androstenedione, dehydroepiandrosterone sulfate, follicle-stimulating hormone, luteinizing hormone, and estradiol levels and Female Sexual Function Index scores. RESULTS: In women treated with radiotherapy (n = 38), median total and free testosterone levels were significantly decreased at 1-year follow-up compared with baseline in premenopausal women (n = 16; total testosterone -29%, P = .01; free testosterone -22%, P = .007) and postmenopausal women (n = 22; total testosterone -25%, P = .03; free testosterone -29%, P = .03). Androstenedione was decreased in premenopausal women only and dehydroepiandrosterone sulfate was decreased in postmenopausal women only after radiotherapy. In women treated with hysterectomy and SOE (n = 10), testosterone levels were lower but not significantly lower, and there was no change in those having surgery without SOE (n = 12). Female Sexual Function Index scores lower than 26.5 in sexually active women were reported by 80% 1 year after radiotherapy, by 44% after hysterectomy with SOE, and by 40% after surgery without SOE, with no significant differences compared with baseline values. No direct correlation between androgen levels and Female Sexual Function Index scores were found at 1-year follow-up. CONCLUSION: Total and free testosterone levels decreased slightly but significantly after pelvic radiotherapy in pre- and postmenopausal women. The clinical importance of this decrease is unclear, but androgen levels were not directly related to sexual function in this pilot setting.
