ABSTRACT

Objective To investigate the effect of intratumor injection of 131 I 3H11 for gastric cancer (GC). Methods 16 patients with GC subjected to endoscopic intratumor injection of 131 I 3H11 as a treatment group; 6 GC patients with FAM chemotherapy as a control group. Histological examination of the postoperative specimens of the two group were comparated. Results In treatment group, 75.0%(12/16) of cases were found to have morphological changes with karyopyknosis, karyorrhexis, coagulation of cytoplasm, and invasion of lymphocyte in mesochyma. Most of these changes were medial; but in control group no obvious morphological change was found. Conclusions The results suggest that GC subjected to endoscopic intratumor injection of 131 I 3H11 preoperatively has promising application in the clinic.
