Local excision for early rectal cancer is a controversial alternative to radical proctectomy. Careful patient selection and consideration of adjuvant therapies are crucial for oncologic outcomes.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Local excision is an alternative to radical proctectomy for rectal cancer.
  • Its oncologic role remains controversial, particularly regarding patient selection and staging accuracy.

Purpose of the Study:

  • To review the oncologic adequacy of local excision for rectal cancer.
  • To evaluate transanal endoscopic microsurgery and salvage surgery outcomes.
  • To provide a treatment algorithm for local excision in rectal cancer.

Main Methods:

  • Literature review of studies evaluating local excision for rectal cancer.
  • Analysis of oncologic outcomes, including nodal metastasis prediction.
  • Inclusion of perioperative adjuvant therapies and salvage surgery data.

Main Results:

  • Local excision is generally reserved for early rectal cancer without nodal metastasis.
  • Accurate prediction of nodal status relies on clinical examination and varied radiologic modalities.
  • Salvage surgery and adjuvant therapies are important considerations post-local excision.

Conclusions:

  • Local excision for rectal cancer requires meticulous patient selection based on accurate staging.
  • The review provides insights into oncologic outcomes and suggests a treatment algorithm.
  • Further research may clarify the optimal role of local excision in rectal cancer management.
