Six hundred and two consecutive cases of gastric cancer and 204 of colorectal cancer in recent decades were investigated for recurrence. Recurrence occurred in 103 cases of gastric cancer and 31 cases of colorectal cancer. We classified three categories of recurrent patterns; A: local, B: peritoneal dissemination, and C: distant metastasis. In gastric cancer, 11 cases (11%) were grouped A, 50 (48%) were B, and 42 (41%) were C. Similarly, 12 (39%) were grouped A, 5 (16%) were B, and 14 (45%) were C in colorectal cancer. The incidence of local recurrence was more increased in colorectal cancer than in gastric cancer (p < 0.01). On the contrary, that of peritoneal dissemination was more increased in gastric cancer than in colorectal cancer (p < 0.01). In gastric cancer, 8 cases of 103 survived more than 5 years after operation, furthermore 7 cases obtained more than 5 years of tumor-free interval. At the time of diagnosis of recurrence, data of serum CEA was available in 77 for gastric cancer and 29 for colon cancer. CEA positive cases were revealed 32 (42%) for gastric cancer and 24 (83%) for colorectal cancer (p < 0.01). Our data clarified the different recurrence patterns between gastric cancer and colorectal cancer. And suggest that more than 5 years follow-up should be needed in patients with gastric cancer.
