Comparison study of quality of life in advanced lung cancer patients on tyrosine kinase inhibitor and platinum doublet chemotherapy.

Abstract

Lung cancer is most common cause of cancer death in the world. Most of the patient are diagnosed in the late stages and receive only palliative treatment. The main objective of the palliative chemotherapy is to improve survival as well as the quality of life (QOL). QOL is the most neglected dimension of cancer care in developing countries like India. Palliative chemotherapeutic agent which has minimum toxicity and prolongs the survival of metastatic cancer patients is the need of the day. In this study, 43 metastatic adenocarcinoma of lung patients of South Indian origin were enrolled. Twenty patients out of this 43 were epidermal growth factor receptor (EGFR) mutation positive and were started on tyrosine kinase inhibitor (TKI). Rest 23 patients were EGFR mutation negative and were started on various platinum-based doublet chemotherapy. QOL was measured using Cancer Institute QOL Questionnaire version 2 at the beginning of therapy and at the end of 3 months. Our study showed that metastatic lung cancer patients had average QOL at presentation. The QOL in patients on TKI improved compared to those on platinum doublet chemotherapy during the second assessment, but this improvement was statistically not significant. In this study, the metastatic lung cancer patients had an average QOL during initial presentation. Patients on TKI had a trend toward better QOL after 3 months of treatment compared to platinum doublet chemotherapy.
