[Surgical treatment of presacral recurrent rectal cancer]

Presacral recurrent rectal cancer (PRRC) which involves the presacral fascia or/and sacral bone is one of the classification of locally recurrent rectal cancer. Presacral fascia or/and sacral bone involvement and posterior fixation make treatment difficult. In recent years, there are many researches on the diagnosis, surgical treatment and surgical methods of PRRC. The major therapeutic principle of PRRC is to perform radical resection with combined therapy under the evaluation of the multidisciplinary team (MDT). Among the surgical methods, abdominal resection or abdominoperineal resection, sacrectomy and abdominosacral resection are the common surgical methods for the treatment of PRRC. Recent articles revealed that limited sacrectomy could also result in good efficacy, provided strict indications for this procedure. With the development of minimally invasive technology, the application of laparoscopic technology in PRRC has been increasingly emphasized. In summary, the surgical principle of PRRC has shifted from solely pursuring radical resection to obtaining good efficacy as well as reduced morbidity with individualized management. In this article, the research progress of surgical methods of presacral recurrent rectal cancer in recent years are reviewed in order to provide reference to clinical diagnosis and treatment.
