The treatment of Acute Lymphoblastic Leukemia (ALL) in children lasts for 2–2.5 years, which consists of an initial 6–7 months of intensive therapy consisting of injections and oral chemotherapy, followed by 2 years of a maintenance phase, which usually consists of oral chemotherapy in the form of daily administration of oral tablets. Most of the maintenance therapy is administered at home, allowing the child to return to normal life, including school and regular activities. Children have regular blood tests to monitor their blood counts and the effect of the medication. The chemotherapy doses are then adjusted based on these results to maintain appropriate blood counts. Our study explores the feasibility of using a web-based mobile application to review the blood tests done by the children at their home and subsequently guide the dosing of medication. We are also looking at the quality of life experienced by the children once the child goes back to their home and rejoins school. We are looking forward to enrolling about 1000 patients through our mobile application service, who would be included in our study. Through this study, we look forward to streamlining and standardising the phase of maintenance therapy in the treatment of acute leukemia and identifying factors responsible for the decrease in compliance and adherence to treatment, as well as the low quality of life experienced by the children and their parents once they return home.
