Targeted Cancer Therapies

7.5K
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...

Cancer Prevention

6.1K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancer Therapies

7.6K
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...

Area of Science:

  • Oncology
  • Nutritional Science
  • Biochemistry

Background:

  • Cachexia is common in non-small cell lung cancer (NSCLC) patients, negatively impacting quality of life and treatment outcomes.
  • Optimal nutritional intervention is crucial for managing cachexia and enhancing cancer therapy response.
  • This study addresses the need for effective cachexia management strategies in NSCLC.

Purpose of the Study:

  • To evaluate the therapeutic efficacy of a specific multinutrient intervention diet on cachexia development in a preclinical lung cancer model.
  • To investigate the impact of the intervention on body weight, muscle mass, and systemic inflammation.

Main Methods:

  • An orthotopic lung cancer mouse model was established using 344P lung epithelial tumour cells.
  • Tumor-bearing mice received either the intervention diet or an isocaloric control diet.
  • Cachexia was defined by five consecutive days of body weight loss; tissues were analyzed post-euthanasia.

Main Results:

  • The intervention diet significantly delayed the onset of cachexia in tumor-bearing mice.
  • Mice on the intervention diet exhibited reduced body weight loss and preserved skeletal muscle and fat mass.
  • Systemic inflammation and molecular markers of muscle atrophy were suppressed by the intervention diet.

Conclusions:

  • The tested multinutrient intervention demonstrates significant potential in managing cachexia associated with lung cancer.
  • This diet, targeting multiple facets of cachexia, could be an integral component of lung cancer management.
  • Further research into this intervention could lead to improved patient outcomes in NSCLC.
