Abstract

Insights

Everolimus shows promise for advanced pancreatic neuroendocrine tumors (pNETs), but its first-line therapy role requires more high-quality data. Current evidence supports its use for symptomatic, unresectable insulin-secreting pNETs to manage endocrine syndromes.

Area of Science:

  • Oncology
  • Endocrinology
  • Pharmacology

Background:

  • Pancreatic neuroendocrine tumors (pNETs) are rare neoplasms.
  • Everolimus is an mTOR inhibitor with demonstrated efficacy in advanced pNETs.
  • The optimal therapeutic positioning of everolimus in pNETs remains under investigation.

Purpose of the Study:

  • To critically review the current evidence for everolimus in advanced pNETs.
  • To evaluate the role of everolimus as a first-line therapy for pNETs.
  • To identify ongoing clinical trials investigating everolimus in pNETs.

Main Methods:

  • Systematic literature review of retrospective and prospective studies.
  • Analysis of international treatment guidelines for pNETs.
  • Comprehensive search of global clinical trial registries.

Main Results:

  • Eight retrospective and two prospective studies were identified.
  • Five ongoing clinical trials and four international guidelines were analyzed.
  • Limited high-quality data exists for first-line everolimus therapy in general pNETs.

Conclusions:

  • High-quality evidence is lacking to support everolimus as a universal first-line therapy for pNETs.
  • Ongoing trials are expected to clarify its future role.
  • Everolimus is recommended as a first-line therapy for symptomatic, unresectable, insulin-secreting pNETs to manage hormonal symptoms.

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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...

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...
