Insights

Brain metastasis incidence is rising, challenging cancer treatment gains. Multidisciplinary research is crucial to overcome the blood-brain barrier and develop new clinical trials for brain metastases.

Area of Science:

  • Oncology
  • Neuroscience
  • Pharmacology

Background:

  • Rising incidence of brain metastasis threatens cancer treatment progress.
  • The brain's sanctuary site status and blood-tumor barrier impede drug efficacy.
  • Need for multidisciplinary approaches to combat brain metastases.

Purpose of the Study:

  • To highlight the need for translational research in brain metastasis.
  • To discuss strategies for overcoming the blood-brain barrier.
  • To review advances in brain metastasis management and cognitive protection.

Main Methods:

  • Review of current research in brain metastasis.
  • Discussion of multidisciplinary research requirements.
  • Examination of advances in chemoprevention, radiation sensitization, and cognitive deficit amelioration.

Main Results:

  • Brain metastasis poses a significant clinical challenge.
  • The blood-brain barrier is a major obstacle for systemic therapies.
  • Multidisciplinary collaboration is essential for effective treatment development.

Conclusions:

  • Advances in chemoprevention offer new strategies.
  • Radiation sensitizers show promise in enhancing treatment efficacy.
  • Mitigating cognitive deficits from radiation therapy is a key research area.

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...

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...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
