The surgery for the patients with intestinal non‑Hodgkin lymphomas: a nationwide study.

ABSTRACT:

Background

The treatment strategy for intestinal non-Hodgkin lymphoma (NHL) and the role of surgery warrant reevaluation.

Methods

This study analyzed clinical data from a cohort of 12,047 patients diagnosed with intestinal NHL, extracted from the Korean National Health Insurance System database between 2002 and 2021.

Results

Among these patients, 3,566 (29.6%) were categorized into the surgery group, while 8,481 (70.4%) were included in the nonsurgery group. Surgery was independently associated with both prolonged overall survival (OS) and a favorable prognosis in multivariate analysis (Hazard Ratio [HR] = 0.645, 95% Confidence Interval [CI] = 0.598-0.695, p <.001). The median OS was longer in patients who underwent lymph node dissection during surgery than in patients who did not undergo lymph node dissection (10-year OS with lymph node dissection 63.17% vs. surgery without lymph node dissection 54.78%, p < .001).

Conclusions

To our knowledge, this is the first Korean population-based nationwide study to describe the clinical impact of surgery on the OS of patients with intestinal NHL. A prospective randomized study evaluating strategies to improve the survival of intestinal NHL patients is needed.
