Total of 146 patients, operated between January, 1974 and December, 1985 for recurrent or metastatic gastrointestinal malignancies were evaluated. Among them, the recurrent stomach cancers were 91 cases and the recurrent colorectal cancers were 37 cases. Age incidence was most prevalent in the 5th decade of life and male to female ratio was 1.1:l. In reoperated stomach cancers the recurrence was closely related to the clinical stage, histologic differentiation or number of metastatic lymph nodes, but in reoperated colorectal cancers those relations were not found. In 83 (64.8%) of 128 cases recurrences were detected within the first 2 years after primary operation and 59 (46.1%) were the local recurrences only. Clinical status due to the recurrences mainly were the intesinal obstruction and recurrence at anastomotic site. In recurrent colorectal cancers, distant metastasis were related with the higher CEA level and local recurrencies were related with the lower CEA level. In 11 (12.1%) of the recurrent stomach cancers and 10 (27.0%) of recurrent colorectal cancers, curative operations were performed. The postoperative complications were 2 cases and postoperative mortalities were 3 cases. The recurrent colorectal cancers revealed the loger survival time than the recurrent stomach cancers, and the curative resections were followed by the higer survival rates than the palliative operations.
