title: The significance of preoperative chemotherapy for early gastric carcinoma.
abstract: In order to achieve a complete prognosis for early gastric carcinoma, a greater effort must be made to improve its present treatment, considering the small percentage of patients who still die from recurrence despite the prompt initiation of surgery. Over the past 9 years, 26 patients with early gastric carcinoma have undergone surgical resection after receiving preoperative chemotherapy in the form of oral 5-FU or 5'-DFUR in our institute. The effectiveness of preoperative chemotherapy was evaluated by histopathological examination of the resected stomachs. Of a total of 24 patients with depressed type gastric cancer, 19 were histologically found to have a cancerless area within the cancerous lesion, 8 of whom were classified as being over Grade 1b. Gross changes were observed in 13 of these 24 patients. The frequency of multiple early gastric cancer occurring in patients who had not received chemotherapy was 11.6%, whereas in those who had received chemotherapy it was 3.8%. The findings of this study thus indicate that preoperative chemotherapy is useful for reducing minute cancer foci and microscopic metastatic lesions.
