Primary non-Hodgkin lymphoma of the stomach--role of surgery.
Thirty-one patients with Non-Hodgkin lymphoma of the stomach were retrospectively investigated. The prognostic factors regarding survival after treatment were determined in an univariate analysis. Twenty-seven of the patients revealed a stage I or II disease (according to the Ann Arbor classification) at the time of operation. The analysis showed no significance for grading, staging, lymph node-, serosa- or splenic involvement of our patients. Significant prognostic factors for survival of gastric Non-Hodgkin lymphomas were age (< 60 years) and resection margins R0 or R1/R2 (p < 0.05). The post-treatment evaluations for prognostic differentation between radical resections, patients with complete response after palliative resection including additional chemotherapy and patients without therapy response showed a significant difference in survival (p < 0.01).
