Insights

Molecular targeted cancer therapies show promise but face challenges like resistance and "negative data." Further research and evidence are crucial for developing effective personalized cancer treatments.

Area of Science:

  • Oncology
  • Pharmacology
  • Genetics

Background:

  • Molecular targeted drugs have yielded significant results in cancer treatment.
  • However, accumulated negative data and challenges hinder the development of some compounds.

Purpose of the Study:

  • Critically discuss five recent issues and problems in molecular targeted therapies.
  • Address challenges in drug discovery, resistance, patient selection, endpoint evaluation, and immunotherapy.

Main Methods:

  • Review of clinical trial data and scientific literature on molecular targeted therapies.
  • Critical analysis of issues including drug resistance, synthetic lethality, and endpoint selection.

Main Results:

  • Drug resistance to targeted therapies targeting driver mutations remains a challenge.
  • Synthetic lethality offers potential for patient selection in personalized medicine.
  • Antiangiogenic therapies like bevacizumab show improved progression-free survival but can increase toxicity.

Conclusions:

  • Development of targeted therapies faces hurdles such as resistance and unclear decision criteria for new compounds.
  • Evaluating immunotherapy efficacy requires robust proof-of-principle studies.
  • Accumulating global evidence is essential for advancing personalized oncologic care.

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 Resistent 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

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

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...
