[What does after care in colorectal cancer accomplish? A prospective study over an 8-year period]

Results of a computer supported follow-up-program on patients with colorectal cancer are demonstrated. Between 1978 and 1985 1024 patients underwent these program, the drop-out-rate was 18%. 231 recurrences in 137 patients were discovered (40% local recurrence, 30% liver metastases and 30% others). 54% of patients with local recurrence and 43% with liver metastases were without symptoms. Radical surgery could be performed in 47% of local recurrences and in 31% of liver metastases. The 3 years survival rate after radical surgery for recurrence was 28% for local recurrences and 31% for liver metastases.
