Colorectal cancer is the third most often encountered type of cancer and represents the third leading cause of cancer related deaths, on both sexes. One of the most important prognostic parameters is the tumor's stage at the time of the diagnosis. T4 cancers represent advanced tumors associated with penetration of the visceral peritoneum (T4a) and/or direct invasion in adjacent structures (T4b). Preoperative diagnosis is influenced by the inability of the existent imaging modalities to accurately differentiate the true invasion from the simple, inflammatory adherence to the neighboring structures. As a consequence surgical treatment must follow the principle of en bloc resection; however the ability of achieving an R0 resection depends on the tumor location, invaded organ, and the type of the surgical procedure required. Neoadjuvant treatment for advanced colon cancer it may be very difficult to be applied. This review is focused on preoperative workup, therapeutic strategies and subsequent results in advanced T4 colon cancers. |
