Role of Hysterectomy in Gestational Trophoblastic Neoplasia

Hysterectomy has a limited role in the management of gestational trophoblastic neoplasia because of the high effectiveness of chemotherapy and the young age of patients. In selected patients, it is believed to help in reducing the number of chemotherapy cycles, overcoming chemo-resistance, and treating acute haemorrhagic events. The present study aimed to evaluate the indications and outcomes of hysterectomy in patients with GTN at a tertiary care centre in India. Between 2012 and 2019, we identified all patients with GTN from the hospital database. Demographic, clinical, and follow-up details of patients who underwent hysterectomy were obtained from the electronic medical records. During the study period, 98 cases of GTN were treated at our centre of which 54% were low-risk and 46% were high-risk cases. Twenty-six patients (26%) underwent hysterectomy as part of their management for GTN. The patients belonging to the high-risk group had more hysterectomies (65%) with an odds ratio of 2.96. The common pathological diagnosis was choriocarcinoma in 44% and an invasive mole in 30% of patients. Bleeding, either intraperitoneal or vaginal, was the most common indication for hysterectomy (48%). The median number of chemotherapy cycles received was 5 in patients who had primary hysterectomy and 6 in patients who did not have hysterectomy. The majority of patients received EMACO (57.7%) chemotherapy. The mean duration of follow-up was 18 months (range 1–67). After treatment, complete remission was achieved in 94 out of 98 (95.9%) and also in all patients (100%) who had undergone hysterectomy as adjuvant procedure. Three patients died during treatment (3.06%), all belonging to the high-risk group, and one patient had a recurrence (0.01%). In selected cases of GTN, hysterectomy may be an effective means to reduce or eliminate tumour bulk, to overcome chemoresistance and manage acute bleeding events.
