Background. Neuroendocrine carcinomas (NECs) of the cervix comprise only 2% of all cervical cancers. Prospective data is limited and treatment guidelines rely on retrospective reviews and literature from lung NEC. The objective of this study was to report our experience in the management of this rare disease.
Methods. This was an IRB-approved retrospective review. Study criteria included patients with cervical NEC diagnosed between 1990 and 2012. Demographic, treatment and survival data was collected. Progression free survival (PFS) and overall survival (OS) were assessed.
Results. Twenty-six patients met inclusion criteria. Advanced-stage disease (II-IV) was diagnosed in 58% (n = 15) of patients. Of the eleven patients with stage I disease, five were treated with platinum-based neoadjuvant chemotherapy (NACT), six with initial radical surgery, and seven received adjuvant therapy including chemotherapy and/or radiation. Nine patients (82%) are currently without evidence of disease (NED). Patients with stage I disease had significantly improved PFS and OS compared to stages II-IV with a median OS that was not reached and 12.1 months, respectively (p = 0.0013). The majority of stage I patients with lymph node metastasis and large tumors achieved durable remission with triple-modality therapy including NACT and surgery followed by adjuvant therapy.
Conclusions. Cervical NEC is an aggressive disease associated with a high mortality rate. Patients with advanced-stage disease have a poor prognosis regardless of therapy. However, multimodality with consideration of triple-modality therapy in early-stage disease has the potential for complete response and long-term survival, supporting the goal of curative intent in these patients.
