Laparoscopic total pelvic exenteration combined with transanal total mesorectal excision for locally advanced prostate cancer with rectal infiltration

IntroductionIntensive treatment is typically considered for very high-risk patients with locally advanced prostate cancer and an expected survival time of 5 years or longer. Herein, we report a case of locally advanced prostate cancer with rectal infiltration treated with laparoscopic total pelvic exenteration combined with transanal total mesorectal excision.Case presentationA 73-year-old man presented with a ring-shaped mass around the rectum. He was diagnosed with prostate cancer with rectal infiltration and underwent laparoscopic total pelvic exenteration combined with transanal total mesorectal excision following neoadjuvant androgen deprivation therapy. Twenty-two months postoperatively during ongoing androgen deprivation therapy, no biochemical recurrence was observed.ConclusionTo our knowledge, this is the first report of a laparoscopic total pelvic exenteration combined with transanal total mesorectal excision for prostate cancer with rectal infiltration. We believe this surgery may be considered a new option for high-risk prostate cancer patients with rectal infiltration.
