[Malignant gastric lymphomas]

Primary malignant lymphomas of the stomach are the most frequent non-epithelial neoplasms of this organ (3%). Their onset and their development are insidious and a proved diagnosis is established only by laparatomy and biopsy specimens. In the absence of proved distant spread, surgical treatment in conjunction with radiation therapy and chemotherapy, gives very good results, with a five years survival rate of 50-70%, even in the presence of regional metastases, and sometimes a final cure is observed.
