| [ Summary ] | Endoscopic therapy is efficient for treatment of submucosal invasive colorectal cancers (sm-ca). Our results suggest that endoscopic therapy for sm-ca may be adapted to sm1a-b cancer, not having invading vessels. Patients who receive endoscopic therapy for sm-ca must undergo a surveillance program, as well as surgical resection. This surveillance, is aimed at cures, for cases which later develop recurrent or metastatic disease. We recommend a surveillance strategy composed ofthese four tests; (1) laboratory tests (complete blood cell count, liver function tests, and CEA), (2) chest radiographs, (3) CT scans, and (4) total colonoscopy (TCS). We check these tests after endoscopic therapy, and perform TCS 3 months later. We should perform annual laboratory tests and TCS for four years after first diagnosis. |
