摘要: Seventy consecutive patients with adenocarcinoma of the colon and rectum had a liver scan followed by surgical exploration liver. Preoperatively, blood chemistry studies were done in addition to palpation abdomen. Surgical findings correlated results scans, function tests The overall concordance scans was 78 percent. Thirty percent false-positive 15 percent, false-negative results. correlation improved increasing extent metastases. When less than 25 replaced tumor, there random findings. By combining tests, metastases could be predicted increased reliability only who severe metastatic disease It is strongly recommended that suggestive most within normal limits undergo establish diagnosis. Exploratory laparotomy seems way avoid chemotherapeutic treatment still allow detection occur at earlier stages.
