66P - Treatment (tx) characteristics and clinical outcomes in patients (pts) with extensive-stage small cell lung cancer (ES-SCLC) treated with carboplatin (carbo) or cisplatin (cis) in combination with etoposide (etop) in US clinical practice (ID 309)
12:30 - 13:00 | Author(s): Phil Arnold
For pts with ES-SCLC, guidelines recommend carbo or cis + etop as first-line (1L) tx. However, real-world data (RWD) on tx patterns and outcomes are limited. Here, we describe pt characteristics, tx duration and clinical outcomes associated with these 2 regimens.a9ded1e5ce5d75814730bb4caaf49419 Methods
Pts with ES-SCLC diagnosis (or limited-stage [LS] SCLC who initiated second-line [2L] tx) between 1 Jan 2013 and 31 Aug 2017 (follow-up to 31 Aug 2018) were identified from the US-based Flatiron Health electronic health record–derived database. Pts receiving tx with either carbo + etop or cis + etop were included in the analysis.20c51b5f4e9aeb5334c90ff072e6f928 Results
RWD on 2161 pts from 156 tx centres were included; 84% of pts received carbo + etop. See table below for pt characteristics. The median tx duration was 3.4 mo (95% CI: 3.4, 3.4) with carbo + etop and 3.0 mo (95% CI: 2.8, 3.4) with cis + etop. The distribution of tx cycles administered was similar between carbo and cis, with 20% and 28% of pts completing 4 or 6 cycles, respectively. Median overall survival (OS) was 8.3 mo (95% CI: 8.1, 8.7) with carbo + etop and 9.7 mo (95% CI: 9.3, 11.0) with cis + etop. The 1-yr OS rates were 30% (95% CI: 28, 33) and 41% (95% CI: 36, 47), respectively. In pts with Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1 and ≥ 2, median OS was 9.3 mo (95% CI: 8.6, 9.9) and 7.1 mo (95% CI: 6.3, 8.3), respectively. Pts with unknown ECOG PS had a median OS of 8.4 mo (95% CI: 8.0, 8.9).fd69c5cf902969e6fb71d043085ddee6 Conclusions
Tx duration was similar between the 2 regimens. Pts who received cis + etop had numerically increased OS vs pts who received carbo + etop, as did pts with ECOG PS 0-1. However, these findings may be due to pts receiving cis + etop being fitter (younger and lower ECOG PS) at baseline.b651e8a99c4375feb982b7c2cad376e9 Editorial acknowledgement
