Background: GOG-0263 is currently investigating the role of adjuvant chemotherapy (CT) concurrently with radiotherapy (RT) in patients with early stage cervical cancer that underwent radical hysterectomy and pelvic lymphadenectomy harboring intermediate risk features. We used a retrospective database to investigate whether adjuvant chemotherapy significantly influenced overall survival (OS), and whether its effectiveness is influenced by delays in radiotherapy. Methods: All data was obtained from the NCDB (National Cancer Database) and initially contained 115,747 cases of cervical cancer diagnosed between 2004 and 2015. Analyzed patients had early stage disease, received radical hysterectomy with pathologic stage I to IIA, and had intermediate risk features including size greater than 4 cm or lymphovascular invasion. All patients received adjuvant RT with or without CT. Cases with positive margin or nodes, with parametrial extension, or metastasis were excluded. Cases were weighted by inverse probability of treatment (CT) using clinical and socioeconomic variables, and analyzed for OS using multivariate models. Predictors of receiving CT were determined using multivariate logistic regression. Results: The final cohort was 557 patients with median follow-up of 43 months (range, 1.54-143.7). Median survival without CT (n = 244) versus with CT (n = 313) was 42.2 versus 43.9 months (HR 0.81, 95%CI 0.661-0.995, p = 0.045). Median time from diagnosis to RT was 91 days (range, 21-691), and predicted for inferior OS (p = 0.007). No significant interaction existed between RT delay and receipt of CT (p = 0.997). Cases with squamous histology were less likely to receive CT than adenocarcinoma histology (OR 0.345, 95%CI 0.159-0.725, p = 0.006). Conclusions: Poor survival outcomes are observed in patients with early stage cervical cancer harboring intermediate risk features when adjuvant radiotherapy is delayed. This outcome was not corrected by addition of chemotherapy.
