Summary
Chemosensitivity testing helps personalize cancer treatment by identifying the most effective drugs and strategies. This approach aims to improve chemotherapy outcomes and overcome tumor resistance.
Area of Science:
- Oncology
- Pharmacology
- Biotechnology
Context:
- Cancer patient response to chemotherapy is highly variable.
- Chemosensitivity testing is increasingly used in clinical settings.
- Tumor cell resistance can limit treatment efficacy.
Purpose:
- To review current chemosensitivity testing methods.
- To evaluate their potential for guiding clinical chemotherapy.
- To establish individualized chemotherapy strategies.
Summary:
- Chemosensitivity assays predict patient response to chemotherapy.
- Methods include cell culture assays (MTT, MTS, ATP), xenograft models, and histoculture.
- These tests help select optimal drugs and exclude resistant tumors.
Impact:
- Facilitates personalized medicine in oncology.
- Improves chemotherapy effectiveness and patient outcomes.
- Reduces exposure to ineffective treatments.

02:50Combination 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...

02:57Targeted 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.

02:56Treatment 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...
01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
