Abstract
AbstractObjectivesIntestinal perforation during acute lymphoblastic leukemia (ALL) treatment in children is rare, but represents a severe complication with possible long‐term consequences. In this study, we aim to provide an overview of the epidemiology and clinical characteristics of these patients; analyze surgical pathology findings for possible causes; and determine its impact on patients’ therapy, nutritional status, and outcome.Study designHistorical chart review from January 2000 to October 2020 of children with ALL and intestinal perforation during therapy diagnosed at a single institution. Data collected included patient demographics, anthropometric measurements, ALL characteristics, diagnosis and surgery of intestinal perforation, pathology, adjustments to treatment plan, and outcome.ResultsOf 1840 ALL patients, 13 (0.7%) presented with intestinal perforation during treatment. Perforation occurred during induction phase in 91% of cases. Most patients underwent laparotomy with ostomy creation, and no patient died from the intervention or developed malnutrition. Pathology mainly revealed inflammation at the perforation site. Two samples showed leukemic infiltration and presence of microorganisms. Patients were able to resume ALL therapy in all cases. A total of eight patients (73%) were in first remission at last follow‐up, with a median follow‐up time of 42 months (interquartile range = 42).ConclusionEarly surgical intervention is a successful treatment approach for intestinal perforation in ALL patients. There is a clear predilection for induction phase in the occurrence of intestinal perforation in ALL patients. No specific cause was identified. Patients can receive bridging chemotherapy during surgical recovery and proceed with their treatment without apparent impact on outcome.
