PURPOSE: To investigate the clinical features and survival outcomes of primary gastrointestinal non-Hodgkin lymphomas (PGINHL) in pediatric and adolescent population, we conducted a population-based cohort study.
METHODS: All pediatric and adolescent patients with PGINHL diagnosed between 2000 and 2019 were identified using the Surveillance, Epidemiology, and End Results (SEER) database. Kaplane-Meier estimations were used to generate survival curves based on various criteria. To compare survival curves, the log-rank test was applied. A multivariate Cox proportional hazards model was developed to investigate the effect of each component on overall survival.
RESULTS: A total of 334 pediatric and adolescent with PGINHL patients were identified. The median age at diagnosis was 12 years (range 1.0-19 years). Tumors were most commonly found in the small bowel (47.3%), followed by the large bowel (42.8%) and the stomach (9.9%). Overall, the most common histological subtype was Burkitt lymphoma (56.9%), followed by diffuse large B-cell lymphoma (DLBCL) (27.8%). Overall survival rates for all patients were 92.2% at 5- year and 91.6% at 10- year, respectively. The Cox proportional hazard regression revealed that only chemotherapy was an important independent predictor in this model. Patients with chemotherapy have a higher survival rate than those without.
CONCLUSIONS: Our study revealed that only chemotherapy was found to be the most important predictor of the OS in pediatric and adolescent PGINHL, providing critical information for therapeutic care.
