Patient profiles, treatment patterns, and outcomes among persistent, recurrent, or metastatic cervical cancer patients under routine care in the United States.

ABSTRACT

OBJECTIVE: Patients with persistent, recurrent, or metastatic cervical cancer have poor prognosis. While recent advances have expanded treatment options, real-world data on treatment patterns and outcomes in this population are lacking. METHODS: This retrospective study identified adult females with persistent, recurrent, or metastatic cervical cancer from the ConcertAI Oncology Dataset who received systemic therapy on or after August 15, 2014. Patients were followed from persistent, recurrent, or metastatic diagnosis through third-line (3 L) therapy, death, end of record, or study end (June 2021). Data collection included patient characteristics, treatment patterns, and clinical outcomes. Kaplan-Meier methods were used for the three most common first-line (1 L) regimens to analyze real-world time on treatment (rwToT), real-world progression-free survival (rwPFS), and real-world overall survival (rwOS). Analyses were stratified by bevacizumab receipt by treatment line. RESULTS: 307 patients were included (mean [standard deviation] age 51.5 [13.2] years, 70.7% White). 91.2% of patients had metastatic disease, 8.5% had persistent disease, and <1% had recurrent disease. The most common 1 L regimen was carboplatin+paclitaxel+bevacizumab (40.7%) with median (95% confidence interval [CI]) rwToT of 3.5 (2.9-4.4) months. 57.0% of patients proceeded to second line (2 L), and 25.7% went to 3 L. Median (95% CI) rwPFS was 7.2 (6.4-8.1) months, and median (95% CI) rwOS was 16.5 (14.2-19.9) months, from initiation of 1 L. CONCLUSIONS: 1 L regimens received in patients with persistent, recurrent, or metastatic cervical cancer generally followed clinical guidelines, and the rwOS agrees with clinical trials. This study highlights the burden of disease and unmet need for specific treatments in these patients.
