Abstract
A 49-year-old woman with a positive fecal occult blood test on medical examination, underwent lower digestive tract endoscopy, and was diagnosed with type 0 -I sp early sigmoid colon cancer of a 20 mm diameter. The polyp was excised by endoscopic mucosal resection and pathologically analyzed. The pathology results revealed a moderately differentiated tubular adenocarcinoma, which had invaded upto the submucosa, with a cancer positive vertical-stump. Laparoscopic sigmoid colectomy (D2 dissection) was performed after two months. No residual tumor cells were found in the resected specimen, which showed four pericolic lymph node metastases (pT1N2aM0, Stage IIIA). As the back pain persisted from perioperative period deteriorated, the patient underwent bone scintigraphy and MRI. Bone metastasis of 2nd thoracic vertebra was susected. The results of a needle biopsy confirmed a diagnosis of bone metastasis of the colon cancer ; hence, she was given chemoradiation. The pain was alleviated ; although the chemotherapy was continued the tumor was at an increased trend, and she died at 1 year and 8 months after surgery.
