RODRIGUEZ-SANJUAN, J. C. et al. Do current indications for surgery of primary gastric lymphoma exist?. Rev. esp. enferm. dig. [online]. 2006, vol.98, n.3, pp.180-188. ISSN 1130-0108.

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.
