Abstract
Aim: The aim was to study the pattern of adverse drug reaction (ADR) provoked by anticancer therapy and to assess the quality of life (QoL) in cancer patients. Materials and Methods: This study was conducted in Tamil Nadu on 75 patients from February to July 2019 taking into account their demographic profile, ADR occurrence and its causality, outcome, organ system-wise distribution of ADRs, and others. The causality assessment was done by using Naranjo's scale and QoL was assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) scale. The QoL was compared in any two consecutive cycles between the 2 nd and 5 th cycles of chemotherapy. Results: Out of the 75 patients, 17 male and 56 female patients developed ADR. A total of 228 ADRs were observed in 73 patients. The most commonly occurred ADR was nausea and vomiting (45%) and the most commonly affected system was gastrointestinal tract (37%). According to causality assessment, the ADR that occurred falls mostly in the category of probable (66.7%) followed by possible (29.3%) and the outcome of the ADR was mostly recovering (49.3%). The QoL was higher in females and in the age group of 40–49 years. The physical and emotional well-being of the patient were affected more. The overall QoL was improved in the 2 nd visit when compared to the 1 st visit. Conclusion: Cancer is known to cause a significant impact on the health and socioeconomics of a nation. To boost the QoL in patients, it is essential to identify and manage the ADRs by taking appropriate measures to promote judicious use of drugs.
