The radiologist's role in the multidisciplinary team for patients with colon cancer peritoneal metastases.

BACKGROUND

Prevention and treatment of peritoneal metastases from colon cancer is currently under a critical reevaluation. An expanded role of the radiologist in imaging the peritoneum and extrahepatic structures is crucial to progress in this endeavor.

METHODS

The critical role of radiology in the evaluation of a primary colon cancer and in diagnosis and assessment of recurrent colon cancer is evaluated.

RESULTS

For primary colon cancer the radiologist should forewarn the multidisciplinary team of patients whose malignancy is at high risk for peritoneal metastases and for local recurrence. In recurrent colon cancer a quantitative assessment of the concerning radiologic features are of help to select patients for reoperation.

CONCLUSION

An improved primary surgical treatment strategy and more knowledgeable patient selection for reoperation can result from this information.
