Insights

Gastrointestinal Stromal Tumors (GISTs) are mesenchymal tumors, with 30% being malignant. Diagnosis and treatment, including surgery and imatinib therapy, are key for managing GISTs.

Area of Science:

  • Gastrointestinal Oncology
  • Surgical Pathology
  • Medical Imaging

Context:

  • Gastrointestinal Stromal Tumors (GISTs) are mesenchymal neoplasms with unpredictable behavior.
  • Malignancy or high malignant potential is observed in approximately 30% of newly diagnosed GISTs.
  • Accurate diagnosis, especially for small or intramural GISTs, can be challenging.

Purpose:

  • To outline current diagnostic and therapeutic strategies for Gastrointestinal Stromal Tumors (GISTs).
  • To highlight the role of imaging modalities and molecular diagnostics in GIST management.
  • To discuss the established and emerging treatment options for GISTs.

Summary:

  • GISTs are diagnosed using histological, immunohistochemical, and molecular genetic assays.
  • Endoscopic examinations and PET/CT imaging are crucial for disease monitoring.
  • Surgical resection is the primary curative treatment for primary GISTs.
  • Imatinib mesylate therapy is recommended for advanced, inoperable, or metastatic GISTs expressing c-KIT.
  • Ongoing research aims to develop novel therapies for advanced GIST and disease prophylaxis.

Impact:

  • Improved understanding of GIST diagnosis and management pathways.
  • Guidance on the application of surgical and biological therapies.
  • Foundation for further research into advanced GIST treatment and prevention.

Myasthenia Gravis: Overview and Treatment01:20

Myasthenia Gravis: Overview and Treatment

Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
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...
Targeted Cancer Therapies02:57

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...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
