Abstract
OBJECTIVE
To characterize the real-world treatment patterns and outcomes of patients with high-risk locally advanced cervical cancer (HR-LACC).
METHODS
This retrospective study identified and randomly selected adults diagnosed between 2010 and 2018 from the ConcertAI Oncology Dataset. For patients initially treated with concurrent chemoradiotherapy (CCRT), we estimated real-world progression-free survival (rwPFS) among those with persistent disease, real-world time on CCRT, and recurrence-free survival (rwRFS) using Kaplan-Meier methods.
RESULTS
The cohort included 300 patients. Median age at diagnosis was 51 years. 53.7 % were White and 30.0 % were Black; 52.0 % were premenopausal; 89.3 % had squamous cell histology; 75.3 % had stage III disease, and 92.7 % had no evidence of performance status impairment. Initial treatment included CCRT (N = 229), surgery (N = 28), antineoplastics only (N = 11), and radiation only (N = 5). Twenty-seven patients were untreated. Baseline characteristics for the CCRT-first patients were similar to the overall cohort; their median real-world time on treatment was 1.6 months; 78.2 % received cisplatin for a median of 1.2 months; 28.4 % received antineoplastics after CCRT, and 11.8 % initiated a second antineoplastic therapy. Of the CCRT-first patients, 27/143 with a complete response had subsequent recurrent disease (median rwRFS not reached). 179 patients had persistent disease, among whom median (95 % confidence interval [CI]) rwPFS was 29.7 (16.9-59.3) months.
CONCLUSION
In this study of United States-based clinical practices, most HR-LACC patients received CCRT as initial treatment. Many patients developed persistent disease after CCRT indicating a need for improved first treatment and maintenance options.
