Summary

This study suggests that tailored surgical approaches for rectal cancer, using total mesorectal excision for lower tumors and wide excision for upper tumors, achieve low recurrence rates.

Area of Science:

  • Colorectal surgery
  • Surgical oncology
  • Rectal cancer treatment

Background:

  • Total mesorectal excision (TME) is standard for mid and low rectal cancers.
  • Its application in upper rectal and rectosigmoid tumors is debated.

Purpose of the Study:

  • To evaluate a tailored surgical strategy for rectal cancer.
  • Compare outcomes of TME for mid/low tumors versus wide excision for upper tumors.

Main Methods:

  • Prospective study of 117 rectal cancer patients.
  • TME for mid/low rectal cancers; 5 cm distal margin wide excision for upper/rectosigmoid cancers.

Main Results:

  • Low locoregional recurrence rates observed (9.3% at 5 years for palliative, 6.5% for anterior resection).
  • Actuarial 5-year cancer-specific survival rate was 81.4%.
  • Anastomotic leak rate was 7.3% after ultralow anterior resection with TME.

Conclusions:

  • A tailored approach combining TME and wide excision is effective.
  • This strategy yields low locoregional recurrence rates for upper rectal and rectosigmoid cancers.
  • This approach may be as effective as routine TME for all rectal cancers.
