Background:

  • Ewing sarcoma is a rare pediatric malignancy defined by specific chromosomal translocations and fusion genes.
  • Recent advancements have identified novel molecular targets for therapeutic intervention.

Purpose of the Study:

  • To review current research on targeted therapies for Ewing sarcoma.
  • To discuss obstacles hindering preclinical and clinical research in this rare cancer.

Main Methods:

  • Literature review of studies on Ewing sarcoma targeted therapies.
  • Analysis of challenges in sample acquisition, animal modeling, and research resources.

Main Results:

  • Despite molecular insights, significant challenges impede targeted therapy development.
  • Pathologist involvement, sample accessibility, and suitable preclinical models are critical bottlenecks.

Conclusions:

  • Overcoming research bottlenecks is crucial for advancing targeted Ewing sarcoma treatments.

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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...

Cancer Therapies02:49

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...
