Critical Reviews in Oncology/Hematology
|December 25, 2025
Summary
Immunotherapy can restore normal cell function, not just kill cancer cells. This review explores how immune responses reprogram cancer cells toward a normalized state, offering a new path for durable cancer remission.
Area of Science:
- Oncology
- Immunology
- Cancer Biology
Background:
- Immunotherapy has transformed cancer treatment through immune activation.
- Emerging evidence highlights immunotherapy's role in cancer cell normalization, termed 'cancer reversion'.
- This shifts the view of the immune system from purely destructive to restorative.
Purpose of the Study:
- To synthesize evidence on immunotherapy-mediated cancer reversion.
- To evaluate mechanistic pathways and clinical implications across various cancers.
- To establish a framework for immune-driven phenotypic normalization.
Main Methods:
- Comprehensive narrative review of literature from 2015-2025.
- Searched PubMed, Web of Science, and Scopus databases.
- Thematic synthesis across immunotherapy types and microenvironmental factors.
Main Results:
- Immune-mediated reversion involves epigenetic, metabolic, and microenvironmental reprogramming.
- Checkpoint inhibitors, CAR-T, and NK-cell therapies promote differentiation and normalization.
- Clinical data across multiple cancers support this restorative immune process.
Conclusions:
- Immunotherapy-mediated cancer reversion is a frontier in oncology, shifting focus from eradication to restoration.
- Future research should define biomarkers, confirm permanence, and redesign clinical endpoints.
- Immune-driven reversion may become a reproducible pathway for durable remission and cure.

1.7K
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.

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

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...

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.

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...

02:40Cancer Stem Cells and Tumor Maintenance
5.8K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
