Abstract:
Stage T4 colon cancer is divided into two categories:tumor penetrating the visceral peritoneum(T4a)and tumor directly invading or attaching to adjacent organs or structures(T4b).Treatment of T4 colon cancer requires technically demanding surgical procedures,including total resection of adjacent infiltrating organs or structures,and is characterized by a high incidence of postoperative complications and a high rate of positive surgical margin microscopy.It has been found that taking laparoscopic surgery for T4 colon cancer may decrease long-term survival and increase the rate of peritoneal metastasis,but taking laparoscopic surgery for colon cancer also has the potential advantages in increasing perioperative benefits and improving the prognosis.With the upgrade of laparoscopic equipment and the improvement of surgeons'surgical skills,more and more surgeons have adopted laparoscopic surgery to treat T4 colon cancer.Currently,the oncologic safety of laparoscopic surgery for T4 colon cancer has not been effectively evaluated.Therefore,this article reviews the advantages,risks,and the choice of treatment strategies for laparoscopic surgery for T4 colon cancer,taking into account the current status and progress of domestic and international studies.
