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...

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...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists01:28

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...
Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Summary
This summary is machine-generated.

Lycopene, a potent antioxidant from tomatoes, may protect against chemotherapy side effects. Its antioxidant and anti-inflammatory properties show promise in reducing drug-induced cellular damage and toxicity.

Area of Science:

  • Oncology
  • Pharmacology
  • Nutritional Science

Background:

  • Antineoplastic agents generate reactive oxygen species (ROS), leading to oxidative stress.
  • Oxidative stress can impede chemotherapy's cytotoxic effects by reducing cancer cell proliferation.
  • ROS contribute to severe side effects like cardiotoxicity, nephrotoxicity, and pulmonary fibrosis.

Purpose of the Study:

  • To review the protective effects of lycopene against chemotherapy-induced toxicity.
  • To explore lycopene's potential to mitigate side effects of antineoplastic drugs.

Main Methods:

  • Literature review focusing on studies investigating lycopene and chemotherapy.
  • Analysis of lycopene's antioxidant and anti-inflammatory mechanisms in relation to ROS.

Main Results:

  • Lycopene, a potent antioxidant, may counteract ROS-induced cellular damage.
  • Evidence suggests lycopene's potential to reduce chemotherapy-related toxicities.
  • Antioxidant and anti-inflammatory properties of lycopene are key to its protective effects.

Conclusions:

  • Lycopene shows promise as a protective agent against chemotherapy-induced side effects.
  • Further research is warranted to establish lycopene's role in supportive cancer care.
  • Lycopene may offer a natural approach to managing chemotherapy-related toxicities.
