Summary
Targeted cancer therapies improve chemotherapy by linking targeting molecules to cytotoxic drugs, reducing toxic side effects. This review explores antibody-drug conjugates and targeted toxins for improved tumor treatment.
Area of Science:
- Oncology
- Pharmacology
- Biotechnology
Background:
- Conventional cancer treatments like chemotherapy face challenges due to dose-limiting toxicities.
- Targeted drug development aims to enhance chemotherapy efficacy by minimizing systemic side effects.
- This review focuses on targeted agents, excluding carrier-based delivery systems.
Purpose of the Study:
- To provide an overview of targeted drug development for tumor therapy.
- To discuss various targeting moieties and conjugation strategies.
- To highlight advanced targeted toxins and enzyme prodrug therapy.
Main Methods:
- Review of scientific literature on targeted cancer therapeutics.
- Analysis of different targeting moieties (antibodies, growth factors, ligands).
- Examination of conjugation methods (chemical coupling, fusion proteins) and novel toxins.
Main Results:
- Targeted drugs utilize specific molecules to deliver cytotoxic payloads directly to tumor cells.
- Antibody-drug conjugates and targeted protein toxins (e.g., diphtheria toxin) show promise.
- Directed enzyme prodrug therapy represents an alternative targeting strategy.
Conclusions:
- Targeted drug development offers a promising strategy to overcome chemotherapy's toxicities.
- Advanced targeted toxins and enzyme prodrug therapies are advancing towards clinical application.
- Targeted therapies represent a significant evolution in cancer treatment paradigms.

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.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:49Cancer 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...

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...
