Cancer therapies face resistance due to genetic changes. However, epigenetic therapy can reverse these changes, making resistant cancers treatable and opening new therapeutic avenues.
Area of Science:
- Oncology
- Epigenetics
- Cancer Therapeutics
Background:
- Cancer progression involves genetic alterations leading to therapy resistance.
- Traditionally, these genetic changes were considered irreversible, necessitating sequential therapies.
- Emerging research highlights the role of epigenetics in chemotherapy resistance.
Purpose of the Study:
- To explore the potential of epigenetic modifications in overcoming cancer therapy resistance.
- To review the reversibility of epigenetic changes that cause chemotherapy resistance.
- To highlight the clinical promise of epigenetic therapy in treating resistant cancers.
Main Methods:
- Review of emerging data on epigenetic changes in tumor progression.
- Analysis of clinical data on the efficacy of epigenetic agents.
- Examination of ongoing clinical trials for epigenetic therapies.
Main Results:
- Epigenetic modifications contributing to chemotherapy resistance are potentially reversible.
- Epigenetic therapy has shown promise in diminishing resistance in various cancers.
- Clinical trials are actively investigating epigenetic agents for resistant disease.
Conclusions:
- Epigenetic therapy offers a promising strategy to re-sensitize resistant tumors to treatment.
- This approach may allow for the re-treatment of patients with previously resistant cancers.
- Further clinical evaluation of epigenetic agents is warranted for resistant malignancies.

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...
