Therapeutic strategy analysis of patients with advanced stage high-grade neuroendocrine cervical cancer: A real-world...

To explore the management of high-grade neuroendocrine cervical cancer (HGNECC) since there has been no standard treatment for it.

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.

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.

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.
