Surgical management of locally advanced and locally recurrent colon cancer.

Overview

Locally advanced and locally recurrent colon cancers pose a surgical challenge with tumors extending into surrounding structures and organs. Anticipation of the need for an extended surgical resection, often with multivisceral en bloc organ removal, is critical for surgical planning. For both primary and recurrent tumors, postsurgical long-term survival is achievable but only after complete resection. The role of neoadjuvant and adjuvant therapy continues to be redefined in this era of biologic chemotherapeutics, and multimodality therapy holds promise in aiding resection and improving postsalvage survival.
