[Results of the surgical treatment of primary gastric lymphoma].
The aim of the study was to verify the long term results obtained in primary gastric lymphoma with a strategy consisting in surgery as first-line treatment. Over the period from January 1988 to December 1999, 44 patients with histologically proven primary gastric lymphoma underwent surgical treatment in the First Department of General Surgery of the University of Verona. Tumours were staged according to the Ann Arbor classification and divided, according to the Kiel classification, into high- and low-grade lymphoma. Patients received adjuvant chemotherapy depending on the grade of malignancy and/or completeness of resection. Of the 44 patients, 40 (90.9%) underwent curative resections, i.e. with complete macroscopic and microscopic tumour removal (R0), consisting in total gastrectomy in 34 cases and subtotal gastrectomy in 6. Twenty-five of 40 patients had stage IE and 15 stage IIE tumours. Adjuvant chemotherapy was given to 33 patients (30 high-grade lymphomas and 3 low-grade lymphomas with N2 metastases). The overall cumulative 10-year survival rate in patients who underwent R0 resection was 79% without any significant differences in 10-year survival between patients with high- and low-grade malignancy (both 79%; P = 0.582) or between patients with or without lymph node metastases (91% and 70%, respectively; P = 0.426). In conclusion, the present investigation suggests that surgery yields prolonged complete remission in a high percentage of patients affected by gastric lymphoma irrespective of histopathologic grade of the disease and nodal involvement.
