Which treatment is indicated for transverse colon cancer?

The treatment indicated for transverse colon cancer is extended right hemicolectomy with ileo-colic anastomosis. This surgical approach involves the removal of the affected segment of the transverse colon along with an appropriate length of surrounding tissue to ensure complete oncological clearance.

In cases where the cancer originates in the transverse colon, it's often essential to have a margin of normal tissue to reduce the risk of recurrence. The extended right hemicolectomy, which includes resection of parts of the ascending colon if necessary, enables thorough evaluation of adjacent lymph nodes and achieves adequate removal of cancerous tissue. Following the resection, the ileum is connected to the remaining colon or rectum through an ileo-colic anastomosis, restoring continuity of the gastrointestinal tract.

Other surgical options, while important in different contexts, do not address transverse colon cancer specifically. For instance, left hemicolectomy would target disease in the left colon, high anterior resection is more appropriate for rectal cancer, and sigmoid resection pertains to lesions in the sigmoid colon. Therefore, the extended right hemicolectomy with ileo-colic anastomosis represents the most effective and appropriate treatment for managing transverse colon cancer.
