Abstract:
There are about 14 million new cancer cases and 8 million deaths every year. Every second man and one in every three women will get cancer during their lifetimes. Following decades of steady increase, death rates have stabilized due to increased awareness and prevention, early detection, and the emergence of more effective therapy. Yet despite all the advances cancer remains a major killer. Despite improved therapies, nearly all current treatments face the same problem: for many patients, they ultimately stop working. Therapy resistance is the ultimate challenge facing cancer researchers and patients today. In this review we present an overview of the most important resistance mechanisms, discussing progress in therapies designed to prevent or overcome anticancer therapy resistance. Finally, we present recent findings from our own laboratory on the development of new experimental models and new therapeutic approaches to combat multidrug resistant cancer.
Insights
Cancer therapy resistance remains a major challenge. This review explores resistance mechanisms and new therapeutic strategies to overcome treatment failure in multidrug resistant cancer.
Area of Science:
- Oncology
- Cancer Research
- Pharmacology
Background:
- Cancer affects millions globally, with significant mortality despite advances.
- Current cancer therapies often fail due to the development of resistance.
- Therapy resistance is a critical obstacle in oncology.
Purpose of the Study:
- To review key mechanisms of anticancer therapy resistance.
- To discuss progress in therapies aimed at overcoming resistance.
- To present novel experimental models and therapeutic approaches for multidrug resistant cancer.
Main Methods:
- Literature review of cancer therapy resistance mechanisms.
- Analysis of current and emerging therapeutic strategies.
- Presentation of original research on new experimental models and treatments.
Main Results:
- Identification and discussion of major cancer therapy resistance mechanisms.
- Overview of strategies to prevent or overcome resistance.
- Introduction of new experimental models and therapeutic approaches for resistant cancers.
Conclusions:
- Therapy resistance is a central challenge in cancer treatment.
- Continued research into resistance mechanisms and novel therapies is crucial.
- Development of new models and treatments holds promise for combating multidrug resistant cancer.

Cancer Therapies
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...
