Insights

Rectal neuroendocrine tumors (NETs) are common and usually detected incidentally. Accurate staging via endoscopy and endoscopic ultrasound is crucial for selecting appropriate treatment, often involving local resection for a good prognosis.

Area of Science:

  • Gastroenterology
  • Oncology
  • Endocrinology

Background:

  • Rectal neuroendocrine tumors (NETs) are the most frequent gastrointestinal NETs, often found incidentally during endoscopy.
  • Most rectal NETs are small, well-differentiated, and associated with an excellent prognosis, with local resection frequently being curative.

Purpose of the Study:

  • To emphasize the importance of accurate initial assessment for rectal neuroendocrine tumors.
  • To highlight the role of endoscopic and endoscopic ultrasound staging in guiding therapeutic decisions for rectal NETs.

Main Methods:

  • Review of current guidelines including European Neuroendocrine Tumor Society (ENETS) 2023, National Comprehensive Cancer Network (NCCN) 2025, and Polish Network of Neuroendocrine Tumors (2017).
  • Emphasis on endoscopic and endoscopic ultrasound (EUS) for staging.

Main Results:

  • Rectal NETs are increasingly detected and represent the most common site for gastrointestinal NETs.
  • Endoscopic and EUS staging are vital for determining treatment, from resection to advanced therapies for advanced disease.

Conclusions:

  • Accurate initial staging of rectal neuroendocrine tumors using endoscopic modalities is essential.
  • Guideline recommendations underscore the need for precise assessment to tailor therapy effectively for rectal NETs.

Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
