Background & ObjectivesVincristine has been used as chemotherapeutic agent for many decades. It implements its function by inhibiting the duplication of tumor cells by destroying the DNA. However, like all other drugs, its administration is not without any side effects. The most important of these are being the neurotoxic side effects. This study evaluated the degree of neurotoxicity induced by vincristine in children who underwent chemotherapy for acute lymphoblastic leukemia and Wilms tumor.MethodsA quasi experimental study was conducted at Children Hospital & the Institute of Child Health, Multan from January 2020 to October 2020 after taking informed written consent. In this study, 150 children of age group 1 - 12 years with pathological confirmation of acute lymphoblastic leukemia and Wilms tumor who had undergone a chemotherapy protocol including at least four consecutive weekly Vincristine injections were included, using probability consecutive sampling technique. Neurological examination was conducted on them on weekly basis.ResultsThere were 150 patients,90(60%) males and 60(40%) females with mean age of (5.5±2.2). Diminished patellar and Achilles tendon reflexes were seen in 48% and 52% of patients. Muscular weakness was seen in 60% of patients. Other side effects like hoarseness, jaw pain, constipation and petosis were observed in 10%, 8%,40% and 10% of patients respectively. Frequency of side effects was equally observed in both sexes and it was more among age group older than five years (p= 0.01).ConclusionVincristine regimen produces some neurotoxic side effects in children but nearly all of these are of mild to moderate in nature.Copyright: © Pakistan Journal of Medical Sciences.
