Abstract
The prognostic factors of primary malignant lymphoma of the gastrointestinal (GI) tract were analyzed in 17 operated patients with using Naqvi's classification that is mainly based on lymph node involvement and depth of tumor invasion. The group of earlier clinical stages, or stage-I and-II (n=11), had 74.1% of 5 year survival rate, while advanced groups, or stage-III and-IV (n=6), had 33.3% (p<0.05). It is therefore indicated that lymph node involvement more than n2 and tumor exposure to the serosal surface were probably definitive prognistic factors. The groups of curative and non-curative operation had 80.0% (n=8) and 42.9% (n=9) of 5 year survival, respectively. The groups with and without adjuvant chemotherapy had 74.0% (n=11) and 33.3% (n=6) of 5 year survival, respectively. As indicated above, curability of operation and adjuvant chemotherapy also significantly influenced on the prognosis. The present study suggested that Naqvi's classification is a useful tool to predict the prognosis of the primary malignant lymphoma of the GI tract.
