title: Abdominosacral resection of recurrent rectal cancer in the sacrum.
abstract: OBJECTIVE
  Resection of the sacrum is the only curative therapy of isolated sacral recurrence after primarily resected rectal cancer. The aim of the study was to assess whether there is a benefit in terms of overall survival, morbidity, and mortality when sacrum resection is performed more radically and in cooperation between colorectal and orthopedic surgeons. Possible prognostic factors were also assessed.
  
  
  METHODS
  Twelve consecutive patients who underwent interdisciplinary partial sacral resection were included in a retrospective cohort study. Furthermore, overall survival rate and survival time were calculated.
  
  
  RESULTS
  Histologic examination showed tumor-free resection margins in all cases. Extended resection was necessary in seven patients, including total pelvic exenteration in two. No perioperative death occurred and no patient required early reoperation. Complications were observed in 42 percent of patients, mainly caused by poor wound healing. All patients experienced relief from pain. One-year and three-year overall survival rates were 50 and 17 percent, respectively. The overall mean survival time was 21.7 months. Patients who died of recurrent disease within one year either underwent former resection for locoregional recurrence, had extensive local recurrent tumors affecting pelvic visceral structures, or retrospectively suffered from metastatic sacral tumor manifestation.
  
  
  CONCLUSIONS
  The mortality and morbidity rates observed in the present study seem to justify partial sacral resection as a means to achieve palliation of perineosacral pain in spite of rare overall long-term survival.
