Objective: Large cell neuroendocrine carcinoma of the cervix (LCNEC) is a rare cervical neoplasm associated with poor survival. Our objective was to identify treatments associated with improved survival.
Methods: Relevant data were abstracted from an English literature MEDLINE search, SEER database, and a patient treated at our institution. Multivariate analysis was performed by generating Cox proportional hazard ratios.
Results: We identified 62 patients with LCNEC: 49 cases from the English literature, 12 patients in the SEER database and our patient. Out of the 62 women, median age was 37 (range, 21-75). FIGO stage was as follows: 58% had stage I disease, 16% had stage II, 2% had stage III, 8% had stage IV disease and 16% had no stage documented. Of all patients, 73% underwent primary surgery, 4.7% underwent primary radiation, 4.7% underwent chemotherapy, 8% had chemoradiation, and 9.6% had no primary treatment. Of all patients, 58% died of disease, 26% had no evidence of disease, 3% were alive with disease, and 13% had no survival data. The overall median survival was 16.5 months (0.5-151 months). Median overall survival for stage I, II, III, and IV cancers was 19, 17, 3, and 1.5 months, respectively. In a multivariate analysis, earlier stage (p<0.00001) and the addition of chemotherapy (p=0.04) were associated with improved survival. Both platinum agents (p=0.034) and platinum and etoposide together (p=0.027) were associated with improved survival.
Conclusions: Perioperative chemotherapy, in particular platinum with or without etoposide, improves survival in the rare LCNEC.
