Summary

Rectal carcinoid tumors, a type of neuroendocrine tumor, are increasingly diagnosed. Localized tumors under 2 cm can be effectively treated with minimally invasive surgery.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Endocrinology

Background:

  • Rectal carcinoids are neuroendocrine tumors with malignant potential.
  • Their incidence is rising, possibly due to enhanced diagnostic methods.
  • The rectum is the third most common site for gastrointestinal carcinoids.

Purpose of the Study:

  • To review current diagnosis, management, and treatment of rectal carcinoid tumors.
  • To emphasize minimally invasive surgical techniques for localized disease.

Main Methods:

  • Review of recent scientific literature.
  • Analysis of diagnostic modalities and treatment outcomes.
  • Focus on surgical resection techniques.

Main Results:

  • Rectal carcinoid tumors show superior survival rates compared to other gastrointestinal carcinoids.
  • Tumor size is a reliable predictor of metastasis and guides management.
  • Localized rectal carcinoids, especially those <2 cm, are effectively treated with local resection.

Conclusions:

  • Increased screening and awareness will likely lead to more rectal carcinoid diagnoses.
  • Minimally invasive resection is a safe and effective option for localized rectal carcinoids (<2 cm, mucosal/submucosal).
