- W3142122489 abstract "Background: Non-small cell lung cancer is one cancer which has seen radical change in treatment in the last decade with the advent of immunotherapy and targeted therapies. Chemo immunotherapy has increased the survival multi fold in metastatic setting and also in earlier lines and is the first line treatment now in non driver mutation setting. However, applicability of the same into real world practice has been dismal in low and middle income countries due to various reasons. Data is lacking in this setting. Methods: We conducted a prospective observational study to see the applicability of Immuno Oncology drug indications in stage 3 and 4 NSCLC patients. Consecutive patients between March 2018 and February 2020 who had an approved indication for IO regimen usage were included. Stage 3b and 3c and stage 4 driver mutation negative patients were taken into the study. Their treatment regimens were studied and reasons for non usage of IO regimen were assessed. Results: Between March 2018 and February 2020, 88 patients were enrolled who were eligible for treatment with IO agents in NSCLC. Among them, stage 3b were 9%, stage 3c were 11.3% and stage 4 were 79.7% patients. Only 30 patients (34%) could receive IO agents in their treatment regimen across various lines of therapy. In stage 4 NSCLC,35.7% patients were treated with IO agents either in the 1st line or later lines. In stage 3, 5 of 18 patients went on to receive IO agent post definitive chemo radiation. The most common reason for non usage of IO agents were financial constraints (68.9%) including exhaustion of insurance limit, denial by insurance company (20.6%) and non availability of drug (10.5%). Of 30 patients who received IO agents, 8 patients had to withdraw owing to financial toxicity while they were still responding with average time to withdrawal being 7.2 months. Conclusions: This observational study depicts the real world scenario of the difficulties in bringing approved regimen into practice with financial toxicity being the reason the non usage in nearly 60% patients. In low income countries, this needs to be addressed if more number of patients are to be benefitted from IO agents in NSCLC. Legal entity responsible for the study: The authors. Funding: Has not received any funding. Disclosure: All authors have declared no conflicts of interest." @default.
