Summary

Sphincter-preserving surgery for rectal cancer is feasible for mid and selected distal tumors. Combining total mesorectal excision with sphincter preservation and optimizing adjuvant therapy improves outcomes.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastrointestinal Surgery

Background:

  • Rectal cancer surgery aims for cure, local control, and preservation of pelvic functions.
  • Sphincter preservation is a key goal in rectal cancer treatment.

Purpose of the Study:

  • To evaluate the integration of sphincter-preserving operations with oncologic goals in rectal cancer.
  • To assess the role of total mesorectal excision and adjuvant therapy in sphincter preservation.

Main Methods:

  • Review of sphincter-preserving procedures for mid and distal rectal cancers.
  • Integration of total mesorectal excision (TME) with sphincter preservation.
  • Analysis of perioperative adjuvant therapy protocols (preoperative vs. postoperative radiation).

Main Results:

  • Sphincter preservation is possible for mid-rectal cancers and selected distal rectal cancers.
  • Total mesorectal excision significantly improves cure and local control and can be combined with sphincter preservation.
  • Preoperative radiation therapy appears to offer better functional outcomes and survival compared to postoperative therapy.

Conclusions:

  • Sphincter-preserving operations are a viable option for rectal cancer, especially with TME.
  • Optimizing adjuvant therapy, particularly preoperative radiation, enhances functional outcomes and long-term sphincter preservation.
  • Evolving surgical standards improve local control, supporting future sphincter preservation efforts.
