Current data of the science and medical practice: evaluation of the discrepancies

Eleven patients with hepatic metastases from colorectal cancer survived more than 5 years after the resection were reviewed. There were 3 (27.3%) disease-free survivors, the longest survival period was 7 years and 2 months. Compared with 41 survivors of less than 5-year duration after resection, it was shown that close follow-up after resection of the primary cancer, detecting early subclinical hepatic metastases, preoperative lower level of CEA, tumor less or equal to 5 cm in size, single metastatic nodule and radical resection were important factors influening long-term survival (P < 0.05). It is of the opinion that early diagnosis, early resection and re-resection after detecting subclinical local recurrence and metastases play important role in improving long-term response.
