JCSE01.18 - A Multicenter Survey of One Year Survival Among Chinese Patients with Advanced Nonsquamous Non-Small Cell Lung Cancer (CTONG1506) (ID 14707)
11:15 - 11:15 | Author(s): Lujing Zhan
- Abstract
Background
Previous results of CTONG1506 study showed that gene aberration test rate was increasing in Chinese NSCLC patients and first-line treatment was standardized accordingly. This survey further described one year survival of patients with different gene aberration status and under different first-line treatments.CTONG1506 was a two-year series cross-sectional study. Patients with advanced nonsquamous NSCLC who were admitted from August 2015 to March 2016 and who received first-line anti-cancer treatment at one of 12 tertiary hospitals across China were included. Data extracted from medical charts were entered into medical record abstraction forms, which were collated for analysis. Survival information was collected one year after patients were admitted to hospital. One year survival rate and its 95% confidence interval were analysed by Kaplan-Meier method.
A total of 707 patients were analysed, with mean age of 57 years and 56.7% were male. Among the 487 patients who had survival data, 192 were EGFR- mutation positive (86 mutated in exon 19 [one year survival rate 0.90, 95% CI: 0.81-0.94] and 88 mutated in exon 21 [one year survival rate 0.84, 95% CI: 0.75-0.90]), 27 patients were ALK positive and 164 patients were EGFR and ALK wild type. Most EGFRmutation positive patients (128/192) received tyrosine kinase inhibitors (TKIs) as first-line treatment and most EGFR wild type patients (155/175) received first-line chemotherapy (Chemo). Pemetrexed was the most common non-platinum chemotherapy-backbone agent (120/155) in platinum doublet regimens. One year survival rates are shown in the table.This national-wide real world study of tertiary hospitals in China revealed that a majority of (>75%) advanced nonsquamous NSCLC patients survived more than one year and was comparable to well-controlled clinical trial results, indicating survival benefits by gene aberration status guided standard of care. This result may be further validated by our on-going two-year survey.
