Safety of hormone replacement therapy in gynaecological cancer survivors.
Therapy for endometrial, ovarian and cervical cancer in young women can cause sudden onset of intense menopausal symptoms, such as hot flushes, emotional disorders and sexual dysfunction. In order to overcome these unpleasant and sometimes severe symptoms, hormone replacement therapy (HRT) has proven to be very effective. However, its safety remains controversial. We reviewed English literature and examined whether administration of HRT in this specific population is related with more recurrences and worse prognosis. Current scientific data, comprising mainly retrospective studies, suggest that recurrence rates and survival are comparable between HRT users and non-users. However, large randomised trials are missing and definitive conclusions cannot be drawn. Gynaecological cancer survivors using HRT, although they seem to have little if any risk for recurrence, should be correctly informed about the lack of strong evidence.
