Abstract
Objective: to analyze the results of our series in order to assess whether surgical excision is still a valid therapeutic option in case the patient needs surgery. Secondarily, to analyze Helicobacter
pylori infection rate.

Patients and method: a retrospective study of 69 consecutive patients having stage IE-IIE primary gastric lymphoma; of these, 65 were treated by gastrectomy between 1974 and 1999.
Mean age: 62.6 years (28-85). New staining of paraffin-embedded samples from the surgical specimen were carried out (hematoxiline-
eosine, Giemsa, immunohistochemistry) and reviewed.
The histological classification was performed according to Isaacson’s criteria. The statistical analysis was done by Chi-squared and
Fisher’s exact tests, as well as Kaplan-Meier and Log-Rank tests.

Results: mortality was 9.2%. There were non-fatal complications in 10.8%. Helicobacter pylori was identified in 62.7%. Seven patients (11.9%) suffered a relapse. The 5-year survival probability
was 87%. The statistical analysis did not show any influences of Ann Arbor stage, gastric wall invasion, Helicobacter pylori infection,
histological type, or margin resection involvement on survival.

Conclusions: surgical excision provides a high rate of complete remissions and excellent long-term survival with acceptable mortality. Therefore it appears to be a valid treatment in case of
emergency surgery, incidental finding, or lack of histological diagnosis.
