Objective: To explore the management of high-grade neuroendocrine cervical cancer (HGNECC) since there has been no standard treatment for it.
Methods: Data on the management of HGNECC were retrospectively analyzed. Patients with FIGO stage IIB to IVB HGNECC from six hospitals were enrolled. The Kaplan-Meier method was used for survival analysis. Prognostic factors were determined using a Cox proportional-hazards regression model.
Results: A total of 43 patients were included in the study. The multivariate analysis showed that chemotherapy was the preferred treatment as it improved progression-free survival (PFS; P = 0.008) and overall survival (OS; P = 0.005). Distance metastasis was a significant negative prognostic factor for OS (P = 0.002), while radical surgery was a significant positive prognostic factor for PFS (P = 0.05). Compared with those who had received cisplatin and etoposide (≥5 cycles), patients who had received paclitaxel plus platinum-based chemotherapy showed better PFS and OS. Five patients (two at stage IIB and three at stage IV) showed relatively long-term survival. Of these patients, four had undergone radical surgery including tumor-debulking, while three also received adjuvant chemotherapy.
Conclusion: Paclitaxel plus cisplatin or paclitaxel plus carboplatin may be more effective than etoposide plus cisplatin. Radical surgery followed by chemotherapy may be a favorable alternative intervention for selected patients with advanced stage cancer.
