ObjectiveTo evaluate the effects of CTX, EADM, VCR, and Pred (CHOP) as preoperative regional intra-arterial infusion chemotherapy in primary gastric malignant lymphoma (PGML). MethodsForty-one patients with PGML underwent preoperative regionalarterial infusion chemotherapy. The regimen consisting of CTX 600 mg/m2, EADM 50 mg/m2, VCR 1.4 mg/m2, and Pred 60 mg/m2, was administrated 14-21 d before operation. Another 33 patients with similar PGML during the same period underwent surgery directly. The response of the tumor and chemotherapy toxicity were observed, together with the survival of the cases. ResultsAmong the 33 patients undergoing surgery directly, 24 cases (72.7%) had curative resection, the 5-year survival rate was 58.3% (14/24). All 41 patients of the neoadjuvant chemotherapy group completed the planned regimen of chemotherapy and surgery successfully. The most common related adverse effects were grade Ⅰ-Ⅱ gastrointestinal discomfort (22 cases) and bone marrow suppression (14 cases). Thirtyseven cases (90.2%) underwent curative resection, the 5year survival rate was 67.7% (21/31). There was no significant difference between two groups in 5year survival rate (χ2=0.517, P=0.471), while with significant difference in curative resection rate (P=0.041). ConclusionsNeoadjuvant intra-arterial infusion chemotherapy (CHOP) has been wellrated; it appears to have improved the resectable rate of the PGML patients studied.
