Abstract

Background

This study aimed to analyze the clinical characteristics and prognostic factors of patients with non-Hodgkin lymphoma (NHL) in the gastrointestinal tract.

Methods

This study investigated patients (n = 456) with gastrointestinal tract NHL who had been initially treated in our hospital between January 2018 and December 2021. We compared clinical characteristics and prognostic factors according to the anatomic site of involvement and histologic subtypes.

Results

Gastrointestinal tract involvement was more common in B-cell than T-cell lymphomas (91.7% versus 8.3%). The intestine (n = 237) involvement was more common than the stomach (n = 219). Patients with T-cell lymphoma were more likely to present with advanced disease and B symptoms than B-cell lymphoma. Subgroup survival analysis was conducted for 358 patients whose follow‐up time was more than 2 years, we found that T-cell immunophenotype and elevated serum lactate dehydrogenase (LDH) were independent prognostic factors for survival. Patients with advanced disease were identified as risk factors for relapsed or refractory gastrointestinal tract NHL.

Conclusions

In our subgroup survival analysis, we found that the survival outcomes demonstrated no significant differences between the stomach and intestinal tract NHL. Serum LDH levels and histologic subtypes were independent prognostic factors for the survival of gastrointestinal tract NHL. Advanced diseases were considered risk factors for relapsed or refractory gastrointestinal tract NHL.
