Abstract

PURPOSE: In Korea, colorectal cancer (CRC) is one of the most sharply-increasing malignancies, and the National Colorectal Cancer Screening Program for persons over 50 years of age began in 2004. To determine the effectiveness of the program, comparative data regarding CRCs treated prior to 2004 must be analyzed. The present study assessed CRC status at diagnosis and treatment patterns in 2003.
METHODS
In 2003, 503 patients were newly diagnosed with CRC and were treated at the Center for Colorectal Cancer, National Cancer Center (NCC). Clinical data were retrospectively reviewed.
RESULTS
The 503 patients included 256 colon and 247 rectal cancer patients. Of the 256 colon cancer patients, 5 (2.0%) were diagnosed during screening colonoscopies and were successfully treated using an endoscopic mucosal resection (EMR), and 17 (6.6%) received only palliative chemotherapy because of distant metastases. Forty patients (15.6%) were treated with palliative surgery and chemotherapy, and 194 (75.8%) with curative surgery with or without adjuvant chemotherapy. Of the 247 rectal cancer patients, 9 (3.6%) were treated with an EMR, 20 (8.1%) with palliative chemotherapy with or without radiotherapy, 19 (7.7%) with palliative surgery and chemoradiotherapy, and 199 (80.6%) with curative surgery with or without chemoradiotherapy. Treatment with curative intent was possible in 199 of 256 (77.7%) colon cancer patients and in 208 of 247 (84.2%) rectal cancer patients.
CONCLUSIONS
Only 12.1% of colon and 8.5% of rectal cancer patients were diagnosed early and treated without adjuvant therapies at the NCC in Korea in 2003.
