ROCHESTER, Minn. — About 20 percent of colorectal cancer patients have cancers that have spread (metastasized) beyond the colon at the time of their diagnosis. The liver is the most common site for these metastases. The approach to treating primary tumors within the colon and metastatic tumors in the liver continues to evolve; however, it typically involves chemotherapy plus surgical removal (resection) of both types of tumors. However, experts continue to debate whether surgical resection of primary tumors and metastatic tumors should be performed at the same time (synchronously) or in separate operations (sequentially).
In the August issue of the Journal of Gastrointestinal Surgery, Mayo Clinic researchers provided a detailed comparison of patient outcomes associated with synchronous and sequential colorectal and liver resections in patients with stage IV colorectal cancer, identifying some benchmarks for surgical practice.
