Insights

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are common advanced gastrointestinal tumors. Targeted therapies like sunitinib and everolimus now offer new treatment options for pancreatic neuroendocrine tumors.

Area of Science:

  • Oncology
  • Gastroenterology
  • Molecular Biology

Context:

  • Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent the second most common group of advanced gastrointestinal tract tumors.
  • Research in GEP-NETs has seen significant growth, highlighting its importance in oncological research.
  • Overexpression of proangiogenic proteins and key intracellular signaling pathways is noted in GEP-NETs.

Purpose:

  • To review the recent advancements in understanding the molecular pathways involved in GEP-NETs.
  • To discuss the implications of new targeted therapies for GEP-NET treatment.
  • To highlight the approval of novel agents for pancreatic neuroendocrine tumors.

Summary:

  • GEP-NETs exhibit overexpression of vascular endothelial growth factor (VEGF) and its receptors.
  • Intracellular pathways, including the epidermal growth factor (EGF) pathway, insulin-like growth factor receptor type I, and PI3K-(PTEN)-AKT-mTOR pathway, are implicated.
  • Recent Phase III studies have led to the approval of sunitinib and everolimus for pancreatic neuroendocrine tumor treatment.

Impact:

  • The approval of sunitinib and everolimus marks a significant breakthrough after decades of limited therapeutic progress for pancreatic neuroendocrine tumors.
  • These targeted agents offer new hope and improved treatment strategies for patients with advanced GEP-NETs.
  • Advances in understanding molecular pathways are paving the way for more personalized GEP-NET therapies.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

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...
Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...
