Real-world Treatment Patterns and Outcomes in Stage III Non-small Cell Lung Cancer: Middle East and Africa – KINDLE Study

Abstract

IntroductionThe Middle East and Africa (MEA)-KINDLE, as part of a real-world global study, evaluated treatment patterns and survival outcomes in stage III non-small cell lung cancer (NSCLC) in the MEA. Materials and MethodsRetrospective data were analyzed from 33 centers for patients diagnosed between January 01, 2013, and December 31, 2017. Descriptive analyses included clinical-demographics and treatment patterns; inferential statistics evaluated an association of first-line treatment with progression-free survival (PFS) and overall survival (OS). ResultsOf 1,046 patients enrolled, the median (range) age was 61.0 years (24.0-89.0); 83.2% were men, 80.8% were current or past smokers, 58.9% had stage IIIA disease, 47.8% had adenocarcinoma and 20.0% of tested (35/175) had epidermal growth factor receptor mutations. Of 86.0% of patients receiving an initial therapy, about 16% underwent surgical resection. Concurrent chemoradiotherapy (cCRT) (32.3%) was the most frequent treatment modality followed by chemotherapy (CT) alone (19.6%) and sequential CRT (12.1%). Median PFS and OS (months, 95% CI) were 11.8 (10.6, 12.4) and 22.9 (21.2, 26.3), respectively for the overall MEA subset. OS (months) was highest with surgery-based therapies for stage IIIA (IIIA: 37.3, IIIB: 24.1) followed by cCRT (IIIA: 28.9, IIIB: 24.4). Female gender, adenocarcinoma, and cCRT or Sx+CRT in first-line were associated with higher OS (P < .05). ConclusionsThe data reveal an unmet need in stage III NSCLC with worse PFS and OS in the MEA subset than in the global cohort. Better access to newer therapies and quality care will be crucial in improving patient outcomes in the MEA.
