Abstract

The aim of this retrospective population-based study was to investigate the survival outcomes and prognostic factors of patients with the two cervical carcinomas. A cohort of patients diagnosed with papillary serous adenocarcinoma of the uterine cervix (PSAC) and papillary squamous cell carcinoma (PSCC) between 1973 and 2015 were drawn from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) were estimated using the Kaplan–Meier method, and prognostic factors were assessed using Cox proportional hazards survival regression analysis. The 5-year and 10-year OS rates were 38.4 and 33.1% for PSAC and 64.6 and 50.8% for PSCC, respectively. The 2-year and 5-year CSS rates were 60.6 and 45.9% for PSAC and 79.6 and 69.0% for PSCC, respectively. Patients with PSCC survive longer than PSAC patients and have other well-described prognostic factors for improved survival rates, including an early cancer stage, a younger patient age and standardised surgery.

    Impact statement

  • What is already known on this subject? Papillary serous adenocarcinoma of the uterine cervix (PSAC) and papillary squamous cell carcinoma (PSCC)are both very rare subtypes of cervical carcinomas.

  • What do the results of this study add? This retrospective population-based analysis has evaluated the survival outcomes and prognostic indicators of patients with PSAC and PSCC.

  • What the implications are of these findings for clinical practice and/or further research? Knowing the survival outcomes and prognostic indicators of PSAC and PSCC patients, we can better follow up patients.
