Small cell carcinoma of the cervix: treatment and survival outcomes of 188 patients.

Abstract

To determine the clinicopathologic factors associated with survival in neuroendocrine small cell cervical cancer patients. Patients were identified from a review of literature with an additional 52 patients from four hospitals. Kaplan-Meier and Cox regression methods were used for analyses. Of 188 patients, 135 had stages I-IIA, 45 stages IIB-IVA, and 8 stage IVB disease. A total of 55.3% underwent surgery, 16.0% had chemoradiation, 12.8% radiation, and 3.2% chemotherapy alone. The 5-year disease-specific survival in stage I-IIA, IIB-IVA, and IVB disease was 36.8%, 9.8%, and 0%, respectively (P < .001). Adjuvant chemotherapy or chemoradiation was associated with improved survival in patients with stages IIB-IVA disease compared with those who did not receive chemotherapy (17.8% vs 6.0%; P = .04). On multivariable analysis, early-stage disease and use of chemotherapy or chemoradiation were independent prognostic factors for improved survival. Use of adjuvant chemotherapy or chemoradiation was associated with higher survival in small cell cervical cancer patients.
