Treatment and clinical outcomes of cervical cancer during pregnancy

This study aims to investigate clinicopathological factors associated with survival rate and treatment of patients with cervical cancer during pregnancy (CCP).

A total of 92 patients diagnosed CCP were retrospectively reviewed. One patient was from Nanfang Hospital of Southern Medical University, 5 patients were from Tongji Hospital, and 86 patients were from case reports in the PubMed database from 1961 to 2019. Patients and tumor characteristics were evaluated. Kaplan-Meier and Cox regression methods were used to analyze the 5-year disease-specific survival (DSS).

Most patients (73 cases) were stage I according to the 2018 International Federation of Gynecology and Obstetrics (FIGO) standards. Twelve patients (13.04%) terminated pregnancy once diagnosed. These patients were diagnosed at the mean gestational age (GA) of 11±3 weeks, during early pregnancy. For the rest of the patients (80 cases) who continued pregnancy, the mean GA was 35±2 weeks at delivery. There was a significant difference in survival whether the treatment was performed once diagnosed or not. The 5-year DSS was 75% in adenocarcinoma (AC), 68.5% in squamous cell carcinoma (SCC), and 43.7% in the rare subtype. Among the 38 patients who underwent neoadjuvant chemotherapy (NACT), one patient suffered from spontaneous abortion, and one baby experienced acute myeloid leukemia (AML) ex-FAB (French-American-British)-M7 subtype and received bone marrow transplantation. Other delivered newborns showed no abnormality or malformation. Cox multi-factorial analysis demonstrated that tumor size (2 cm) was an independent overall survival predictor for CCP patients (P<0.05).

Tumor size was an independent prognostic factor of survival in CCP patients. Pregnancy has adverse effects on the prognosis of cervical cancer. Personalized treatment is a priority for CCP patients.
