Abstract :
Cancer chemotherapy is rampant as cancer is the 2nd most common cause of global mortality. It is challenged by a horde of adverse drug reactions (ADRs) and adverse events. A proper study of these ADRs is very crucial to limit their occurrences and thereby ameliorate the sufferings of the patients. Our study was to assess the frequency, nature and profile of the ADRs with anticancer drugs. A retrospective analysis of the ADR data collected over a period of 5 years was considered. Demography, drug related changes and clinical details of the patients were recorded and analysed. A total of 1145 ADR events were reported during the study period of January 01, 2017 to December 31st 2021 of which 232 cases (20.26 %) were due to anticancer drugs. The majority of the ADRs were accounted in females and in the elderly age group (>60 years). The commonly reported ADRs included breathing difficulty, chest discomfort, itching all over the body, numbness, neuropathy, mucositis and hand foot syndrome. The most common drugs that caused ADRs were Platinum coordination complex drugs, Taxanes, Rituximab and pyrimidine antagonists like Capecitabine and Gemcitabine. Causality assessment done using WHO-Uppsala Monitoring Centre causality assessment scale which showed 69.4% cases as “probable”, 29.3% cases as “possible” and 1.3% as “certain”. Severity assessed using the modified Hartwig and Siegel scale showed most of the cases as of moderate severity. Most of the ADR events in our study was manageable although a few required the withdrawal of the causative drug. Rigorous monitoring and adequate reporting are very crucial for the prompt identification, assessment and timely management of ADRs in the patients receiving chemotherapy so as to improve the quality of life in these patients.
