Pharmacoeconomic benefit of cisplatin and etoposide chemoregimen for metastatic non small cell lung cancer: An Indian study.

BACKGROUND

The incidence of lung cancer is rising in developing countries like India. Due to unaffordability among the low socioeconomic status (SES) patients, there is a significant delay in seeking appropriate medical treatment due to which a high proportion of patients present in an advanced/metastatic stage and the outcomes are poor.

OBJECTIVE

In this study, we studied the progression-free survival (PFS) and the pharmacoeconomic benefits with the cisplatin plus etoposide (EtoP) chemo regimen and compared it with the current generation chemo regimen.

MATERIALS AND METHODS

We performed a retrospective analysis of metastatic nonsmall cell lung cancer patients who received one or more cycles of platinum-based chemotherapy between 2011 and 2014.

RESULTS

Of the 304 patients, 56.6% of the patients were of the low SES. Of the low socioeconomic group patients, 67.45% and 31.4% received etoposide and paclitaxel platinum doublet combination regimen as first line, respectively. The mean PFS with the etoposide, paclitaxel, pemetrexed, and gemcitabine platinum-based doublet regimens were 9.35, 10, 10.76, and 9.83 months, respectively. Kaplan-Meier survival curve analysis showed a statistically significant initial survival with the first line EtoP cisplatin regimen for the initial 6 months of starting chemotherapy in comparison with the other regimens.

CONCLUSIONS

This study showed a substantial pharmacoeconomic benefit with the cisplatin and etoposide chemo regimen in the lower socioeconomic group of patients. We believe that this is the first pharmacoeconomic study on metastatic non small cell lung treatment of great relevance to countries with limited resources.
