  • Look Inside

 The patient was 65 year-old male who visited our clinic because of constipation and bloody stool. Rectal examination disclosed a polyp of type III by Yamada's classification, measuring 1.5×1.5 cm, at 8 cm from the anal verge. Polypectomy was performed and histological examination showed well differentiated adenocarcinorna invading down to the submuosa. In addition to the polypectomy, therefore, resection of the rectum was performed. Shortly after the polypectomy CEA titer was 240 ng/ml but it dropped down to 13.8 ng/ml after the resection of the rectum. During the post-operative follow-up, however, the CEA titer again jumped up to 305 ng/mi and repeated CEA titers were continued to be high. Therefore, extensive work-up for searching a metastatic lesion was carried out and abnormal shadow in the right upper lung field was found. It was felt lung metastasis and resection of the lesion was performed. Indeed, histologic examination showed lung metastasis of the rectal cancer and CEA titer fell down to 2.5ng/ml after the resection. Furthermore, the resected specimen was stained by fiuorsceinantibody method and it demonstrated the production of CEA in the tissue.
