Advanced Approaches in Treating Metastatic Colorectal Cancer

Colorectal cancers develop in the lower digestive tract, including the colon and rectum. Even after early detection and intervention, these cancers can recur later, even if initially removed. Recurrence may happen at the original site, nearby tissues, or distant organs—a process called metastasis when spread occurs to distant locations. Sometimes, by the time of diagnosis, cancer has already metastasized, often classified as stage IV. Treatment options include surgery for limited metastases, especially in the liver, but not all cases are suitable. Combining chemotherapy and immunotherapy can also help extend survival, although a complete cure remains rare.
