Background: In 2021, 14,480 patients are estimated to be diagnosed with cervical cancer in the US; 16% of patients are expected to have metastatic disease for whom the 5-year survival rate is 17.6% per SEER estimates. Patients with metastatic cervical cancer (mCC) are treated mainly with systemic therapy. This study aims to describe the clinical characteristics, demographics, treatment patterns, and economic burden of patients with mCC receiving systemic therapy. Methods: Eligible women had been diagnosed with cervical cancer, as evidenced by >2 outpatient or >1 inpatient claim in the Optum Research Database from January 2014 through January 2020. Patients were included if they had metastasis within 6 months before or after cervical cancer diagnosis, with evidence of systemic treatment on or after the latter of a claim date for cervical cancer disease or metastatic disease. The index date was the first-line treatment initiation date. Patients were required to have ≥6 months of pre-index continuous enrollment. The top 3 treatment regimens and median treatment duration by line of therapy were described. All-cause per-patient-per-month (PPPM) costs (2019 US dollars), including plan and patient paid amounts, were reported for full follow-up period from first-line and second-line therapy initiation. Results: The study sample consisted of 778 patients (mean age, 59 years; commercial, 58%; Medicare Advantage, 42%). The mean (median) follow-up period was 14 (9) months. Top baseline comorbidities were diseases of the urinary system (71%) and diseases of the female genital organs (70%), and the median Charlson comorbidity index was 7. In the first line, 80% of patients received platinum-based therapy and 23% received bevacizumab (bev). Of 778 patients, only 294 (38%) received second-line therapy, with 34% receiving bev. Top first-line treatment regimens were carboplatin + paclitaxel (27%), cisplatin (21%), and bev + carboplatin + paclitaxel (10%); the median (95% CI) duration of treatment was 3.4 (3.1-3.7) months. Top second-line treatment regimens were bev + carboplatin + paclitaxel (13%), carboplatin + paclitaxel (11%), and pembrolizumab (6%); the median duration of treatment was 3.8 (3.1-4.2) months. Mean all-cause total PPPM costs were $19,519 from first-line and $22,660 second-line therapy initiation (table). Conclusions: This study indicates that real-world mCC patients have short treatment durations and significant economic burden with first-line and second-line therapy. Novel therapies associated with greater clinical benefits in patients with mCC may provide economic benefit.
