Abstract:
36 patients with primary gastric non-Hodgkin's lymphoma (PGL) (stage Ie and IIe) were treated at the Comprehensive Cancer Center of Aviano (PN) Italy. The median follow-up time of the patients was 59 months (range 10 to 117). The pre-operative diagnosis of PGL was established by using endoscopy in 70% of the patients. There was understaging in non-invasive methods of diagnosis in comparison to laparotomy. Prognostic factors such as: stage, grade according to the Working Formulation, size, depth of penetration of the gastric wall and resectability of the tumor, were taken into consideration in the treatment plan. This consisted of surgical resection of the gastric lymphoma where feasible and according to the bad prognostic factors escalating adjuvant treatment was included: group I (n = 6) patients were treated only by surgery (S), II (n = 8) by S+radiotherapy (RT) (n = 5) or S+chemotherapy (CT) (n = 3), III (n = 17) by S+RT+CT and IV (n = 5) by non-resectable S+RT+CT. There were no statistically significant differences in the survival rate, calculated by Kaplan-Meier method, between the first three groups of patients. Only stage of disease (P = 0.048) and resectability of the lesion (P = 0.003) had a significant influence on survival. There were no serious complications observed in either S, RT or CT treatment. The estimated 5-year survival rate after management was 100%, 75% and 88%, respectively for stage Ie (n = 21), stage IIe (n = 15) and all together.
