[An evaluation of the benefits and drawbacks of total pelvic exenteration in the treatment of rectal cancer].

Abstract

Total pelvic exenteration (TPE) is widely regarded as the most effective intervention for the management of primary locally advanced rectal cancer and locally recurrent rectal cancer. However, TPE presents several challenges, including the potential for failing to achieve R0 resection, high incidence of complication, decreased postoperative quality of life, and the possible overtreatment in patients without carcinomatous adhesions or with only inflammatory adhesions, as well as in those who achieve pathological complete response after neoadjuvant therapy. In the context of precision medicine, further investigation is necessary to enhance the accuracy of preoperative diagnoses of extrarectal cancer invasion and to explore the comprehensive application of genetic molecular typing methods alongside innovative neoadjuvant treatment strategies. Such research should aim to enhance the R0 resection rate of TPE, minimize surgical complications and mortality, improve postoperative quality of life, and achieve an optimal balance between radical resection and the preservation of organ function.
