[Clinico-pathological study on recurrent gastric cancer after curative resection].
Among 675 patients who had undergone curative resection of gastric cancer during last 13 years, 113 died of cancer recurrence. One hundred and forty-five patients who had survived longer than 5 years were used as controls. In the recurrence group, the primary lesion was larger and the lymph node metastasis more common as compared with the surviving controls. Moreover, these lesions were often located at the upper third of the stomach and exhibited Borrmann 3 or 4 type. Prognostic serosal invasion was positive in 75 per cent of the recurrence group and negative in 84 per cent of the surviving controls. The most frequent mode of recurrence was hematogenous metastasis in negative prognostic serosal invasion (54%) and peritoneal disseminated metastasis in positive prognostic serosal invasion (52%). There were no differences in the distribution of gross and histological types of cancer in the modes of recurrence. It was found that peritoneal dissemination and/or local recurrence dominated as the mode of recurrence (51%), followed by hematogenous metastasis (34%), but that lymph node recurrence was uncommon (15%). In peritoneal disseminated cases, long-term survival following reoperation should not be expected. It was suggested that in order to improve the prognosis in the case of hematogenous metastasis, postoperative immunochemotherapy should be applied.
