Differences in multidisciplinary team assessment and treatment between patients with stage IV colon and rectal cancer.
OBJECTIVE
At diagnosis, 14-27% of patients with colorectal cancer (CRC) have distant metastases (stage IV) and a poor prognosis. Today, treatment decisions for CRC patients are often made at multidisciplinary team (MDT) conferences. The aim of this study was to evaluate the effects of development and implementation of MDT assessment and treatment in patients with stage IV colon cancer (CC) and rectal cancer (RC) in a large population.


METHODS
All 1449 patients who had stage IV CRC at the time of diagnosis and were registered in the regional quality registry of Stockholm from 1995 to 2004 were included. Patients with CC and RC were grouped according to treatment and their characteristics were analysed separately.


RESULTS
In total, 1000 patients with CC and 449 patients with RC had stage IV disease. Of these, 689 (68.9%) CC patients and 352 (78.4%) RC patients were assessed by a MDT and the proportion increased over the study period (P < 0.001). Surgery for metastases was undertaken on 39 (3.9%) CC patients and 38 (8.5%) RC patients (P < 0.001). CRC patients selected for metastasis surgery had 37% 5-year survival when compared with 2% in patients who were not selected for metastasis surgery (P < 0.001).


CONCLUSIONS
Patients with CC were less often assessed by a MDT and less often had metastasis surgery than RC patients. The proportion of patients with CC and RC assessed by a MDT increased during the study period, as did the proportion who had surgery for metastases. MDT assessment opens up the opportunity for more aggressive treatment with better outcomes.
