Abstract:
Nowadays there are several limitations in cancer treatment. One of these is the use of conventional medicines which not only target cancer cells and thus also cause high toxicity precluding effective treatment. Recent elucidation of mechanisms that cause cancer has led to discovery of novel key molecules and pathways which have have become successful targets for the treatments that eliminate only cancer cells. These so-called targeted therapies offer new hope for millions of cancer patients, as briefly reveiwed here focusing on different types of agents, like PARP, CDK, tyrosine kinase, farnysyl transferase and proteasome inhibitors, monoclonal antibodies and antiangiogenic agents.
Insights
Conventional cancer treatments cause toxicity. Novel targeted therapies, including PARP inhibitors and monoclonal antibodies, offer effective cancer cell elimination with reduced side effects, providing new hope for patients.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Conventional cancer treatments often exhibit significant toxicity, impacting treatment efficacy and patient outcomes.
- Understanding cancer's underlying molecular mechanisms has revealed specific targets for more precise therapeutic interventions.
Purpose of the Study:
- To review novel targeted therapy agents for cancer treatment.
- To highlight advancements in eliminating cancer cells while minimizing toxicity.
Main Methods:
- Literature review of targeted cancer therapies.
- Focus on specific classes of agents including inhibitors and antibodies.
Main Results:
- Targeted therapies selectively eliminate cancer cells by inhibiting key molecules and pathways.
- Agents reviewed include Poly (ADP-ribose) polymerase (PARP) inhibitors, cyclin-dependent kinase (CDK) inhibitors, tyrosine kinase inhibitors, farnesyl transferase inhibitors, proteasome inhibitors, monoclonal antibodies, and antiangiogenic agents.
Conclusions:
- Targeted therapies represent a significant advancement in cancer treatment, offering improved efficacy and reduced toxicity.
- These novel approaches provide new hope for cancer patients by targeting cancer-specific mechanisms.

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...
