Summary

Local excision offers a curative option for early rectal cancers and benign tumors, especially in elderly patients. While recurrence is possible, early detection and adjuvant radiotherapy can manage it, enabling organ preservation.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Rectal Cancer Treatment

Background:

  • Local excision is a standard treatment for benign rectal tumors and early-stage rectal cancers.
  • This minimally invasive approach offers curative potential for pT1 disease with preserved quality of life.
  • It is a suitable option for elderly or medically comorbid patients.

Purpose of the Study:

  • To review the role and outcomes of local excision in managing benign rectal tumors and early-stage rectal cancers.
  • To discuss the risk factors for local recurrence and strategies for its management.
  • To evaluate local excision as an organ-preserving option compared to other treatment modalities.

Main Methods:

  • Review of established treatment protocols and outcomes for local excision in rectal surgery.

  • Analysis of pathological risk factors influencing local recurrence rates.
  • Evaluation of surveillance strategies and adjuvant therapies for recurrent rectal cancer.

    • Main Results:

    • Local excision provides cure for most pT1 rectal cancer patients with minimal impact on quality of life.
    • Recurrence rates after local excision can range from 5% to 30%, depending on pathological factors.
    • Early detection and adjuvant radiotherapy can effectively manage local recurrence.

    Conclusions:

    • Local excision is a valuable organ-preserving treatment for carefully selected patients with early-stage rectal disease.
    • It offers a realistic alternative to radiotherapy or total neoadjuvant treatment.
    • Intensive surveillance and timely intervention are crucial for managing potential local recurrences.
