Treatment patterns in cervical cancer patients initiating systemic therapy.
e18009 Background: NCCN recommends the use of systemic treatment for advanced cervical cancer patients. However, no study has assessed treatment patterns in this population. This study described real-world treatments patterns among women with cervical cancer newly initiating a systemic therapy. Methods: Cervical cancer patients with ≥2 claims for systemic therapy (i.e., chemo- or immunotherapy) within a 4-week period between June 2014 – October 2018, no claims within 6 months prior to systemic treatment initiation (baseline period), and continuously enrolled within the baseline period and 3 months post therapy initiation were identified from the Optum Clinformatics DataMart database. Patients who had a cervical cancer-related surgery within ±3 months of therapy initiation were excluded to exclude adjuvant use. All claims for the same systemic therapy without a > 90-day gap or new systemic therapy started within 28 days of a previous treatment were considered to be part of the same LOT. Descriptive analysis, stratified for presence of non-cervical cancers during the baseline period, were conducted to identify most common treatments, durations, and use of mono versus combination therapy within each LOT. Results: 1,229 women newly initiated systemic therapy, 357 (29.0%) received LOT2 and 141 (11.5%) had a LOT3. Treatments received within each LOT are described in the table below. The proportion receiving radiation reduced from LOT1 (49.9%) to LOT2 (12.0%). The mean duration of LOT1 and LOT2 were 2.9 and 3.7 months. The proportion of patients receiving monotherapy in LOT1 and LOT2 were 77.8% and 64.1% respectively. Conclusions: The treatment received by patients in this analysis suggested receipt of guideline concordant care. [Table: see text]
