Summary

Colorectal cancer surgery aims for cure and preventing recurrence. Total mesorectal excision (TME) surgery significantly lowers local recurrence rates in rectal cancer patients.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Colorectal cancer is a leading cause of cancer mortality in North America and Western Europe.
  • Surgery is the primary treatment modality for colorectal cancer.
  • Rectal cancer presents unique challenges in achieving curative resection and preventing local recurrence.

Purpose of the Study:

  • To review the surgical management of colorectal cancer, focusing on achieving cure and minimizing locoregional recurrence.
  • To evaluate the role of surgical techniques and adjuvant therapies in improving outcomes for rectal cancer patients.
  • To identify areas requiring further research in the surgical treatment of colorectal cancer.

Main Methods:

  • Review of current surgical techniques for colorectal cancer, emphasizing the importance of adequate circumferential tumor margin excision.
  • Discussion of the impact of total mesorectal excision (TME) on locoregional recurrence rates.
  • Evaluation of the role of adjuvant radiotherapy (pre- and post-operative) in managing rectal cancer.

Main Results:

  • Total mesorectal excision (TME) is associated with the lowest rates of locoregional recurrence in rectal cancer.
  • Improvements in surgical technique and adjuvant radiotherapy can reduce local recurrence rates.
  • Potential complications of rectal excision include anorectal, sexual, and urinary dysfunction.

Conclusions:

  • TME is a critical surgical technique for minimizing recurrence in rectal cancer.
  • The role of adjuvant radiotherapy in conjunction with TME requires further investigation due to the low recurrence rates achieved with TME alone.
  • Further research is needed to clarify the optimal surgical management for specific scenarios, including transanal excision, laparoscopic surgery, and obstructed cases.
