[Primary gastric lymphoma: a retrospective series of 35 cases].
BACKGROUND
Primary gastric non Hodgkin's lymphoma (PGNHL) is the most common site of extranodal malignant lymphoma. It is a rare subtype of malignancy, for which no consensus exists about treatment.


OBJECTIVE
The purpose of This paper was to assess the managemnt of PGNHL.


METHODS
Between January 1992 and December 2001, 35 patients were retrospectively evaluated.


RESULTS
Of the 35 patients, with a mean age of 44 years old Signs and symptoms are unspecific. 20 (57.1%) were in stage IE/IIE1. 15 patients (42.8%) were in stage IIE2,IIIE,IVE. These patients were treated with primary surgery with or without chemotherapy (11; 31.4%); primary chemotherapy (CT) alone with surgery in one patient (21; 60%) and three patients with gastric MALT lymphoma were treated by Helicobacter pylori eradication. The 5 year survival rates of the 35 patients are 62, 86%. There was no significant difference in the 5 year survival rate between the patients with low grade lymphoma and the patients with large grade lymphoma (75% versus 60%, P = 0.467). The 5-year survival rates for stage I/IIE1 and IIE2/III/IV patients were 80%, 53.3% respectively (p < 0.144). Of the 11 primary surgical groups with or without chemotherapy, the 5 year survival rate is 90.9%. Of the 21 patients who received CT, alone or combined with surgery, the survival rate is 52.4%. There was significant difference between the two groups (P = 0.05). Of the 3 patients with low-grade mucosa-associated lymphoid tissue (MALT) lymphoma with only oral anti-Helicobacter pylori regimen remained disease-free after a median follow-up of two years.


CONCLUSIONS
This study suggested that primary surgical resection may be important factor predicting the long-term survival of patients with primary gastric NHL. H. pylori eradication therapy was an effective first-line treatment for patients with gastric MALT lymphoma.
