Insights

Surgery is the main treatment for most gastroenteropancreatic neuroendocrine tumors (NETs), especially when metastatic. Medical therapies also improve survival for advanced, unresectable NETs.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Neuroendocrine tumors (NETs) are a diverse group of neoplasms with varied clinical presentations.
  • Metastatic disease, particularly to the liver, is frequently observed at diagnosis.
  • Current surgical management guidelines for NETs are primarily based on retrospective data due to a lack of randomized controlled trials.

Purpose of the Study:

  • To review the current role of surgery and medical therapies in managing gastroenteropancreatic neuroendocrine tumors (NETs).
  • To highlight the importance of cytoreductive surgery for symptom and survival improvement.
  • To emphasize the evidence supporting medical therapies for advanced and unresectable NETs.

Main Methods:

  • Review of retrospective studies on surgical management of gastroenteropancreatic NETs.
  • Analysis of prospective randomized data for medical therapies in advanced NETs.
  • Evaluation of the role of cytoreduction in improving patient outcomes.

Main Results:

  • Surgery is considered the primary treatment modality for most gastroenteropancreatic NETs.
  • Cytoreductive surgery can lead to improvements in both symptom control and patient survival.
  • Prospective randomized trials demonstrate that medical therapies enhance progression-free and overall survival in patients with advanced, metastatic, and unresectable NETs.

Conclusions:

  • Surgical intervention remains a cornerstone in the management of gastroenteropancreatic NETs.
  • Cytoreduction offers significant benefits for symptom management and survival.
  • Medical therapies are crucial for improving outcomes in patients with advanced and unresectable NETs.

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...

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...

Structures of the Endocrine System00:59

Structures of the Endocrine System

The intricate framework of the endocrine system encompasses a diverse array of glands, with their target tissues and organs strategically distributed throughout the body. Central to this network are the endocrine glands, specialized structures that lack ducts and release hormones directly into the interstitial fluid. Notably, the hypothalamus, a vital neuroendocrine organ situated in the brain, governs neural functions and serves as a potent source of hormonal regulation. Near the hypothalamus...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
