Epigenetic Therapy is an innovative approach to cancer treatment that focuses on modifying the expression of genes without altering the genetic code itself. By targeting the mechanisms that control gene activity, epigenetic therapy can reactivate tumor suppressor genes or silence genes that promote cancer growth. In this guide, we explore how epigenetic therapy works, its benefits, and the leading hospitals offering this treatment in India.
What is Epigenetic Therapy?
Epigenetic Therapy is a type of cancer treatment that aims to change the activity of genes without modifying the DNA sequence itself. Instead, it influences the "epigenetic" marks on DNA or associated proteins that control gene expression. These changes can turn off cancer-causing genes or turn on tumor-suppressing genes, offering a novel way to treat cancer.
How Does Epigenetic Therapy Work?
Epigenetic therapy works by targeting the chemical tags or modifications that affect how genes are turned on or off. Drugs used in this therapy focus on enzymes like DNA methyltransferases and histone deacetylases (HDACs), which are responsible for adding or removing these tags. By modifying these enzymes, epigenetic therapy can restore normal gene function and inhibit cancer growth.
Types of Epigenetic Therapy
There are several types of epigenetic therapies used in cancer treatment, each focusing on different epigenetic mechanisms:
- DNA Methylation Inhibitors: These drugs block the enzymes that add methyl groups to DNA, helping reactivate tumor-suppressor genes that were silenced by methylation.
- Histone Deacetylase (HDAC) Inhibitors: These drugs affect the proteins that package DNA, making it more accessible for genes to be expressed. This can prevent cancer cells from multiplying.
- Histone Methyltransferase Inhibitors: These inhibitors target enzymes that add methyl groups to histones, which can promote cancer cell growth if left unchecked.
Which Cancers Can Be Treated with Epigenetic Therapy?
Epigenetic therapy is particularly effective for certain types of blood cancers, such as leukemia and lymphoma. Some cancers that respond well to this treatment include:
- Acute Myeloid Leukemia (AML): Epigenetic therapy can help treat AML by reactivating tumor-suppressor genes.
- Myelodysplastic Syndromes (MDS): Patients with MDS benefit from epigenetic drugs that alter abnormal gene expression.
- Non-Hodgkin’s Lymphoma: Certain types of lymphomas respond to drugs that affect histone modifications.
- Solid Tumors: Ongoing research is investigating the use of epigenetic therapy for solid tumors, such as lung, breast, and prostate cancer.
Benefits of Epigenetic Therapy for Cancer Treatment
Epigenetic therapy offers several unique advantages in cancer treatment:
- Targeted Treatment: It specifically targets the epigenetic changes driving cancer growth, offering a more focused approach.
- Combination Therapy: Epigenetic drugs can be used alongside chemotherapy, radiation, or immunotherapy to enhance their effectiveness.
- Fewer Side Effects: Since epigenetic therapy targets specific mechanisms in cancer cells, it often causes fewer side effects compared to traditional chemotherapy.
Side Effects of Epigenetic Therapy
Although epigenetic therapy is generally well-tolerated, it can still cause some side effects, including:
- Fatigue
- Nausea
- Low blood cell counts
- Increased risk of infection
These side effects are typically milder than those caused by conventional cancer treatments like chemotherapy.
Epigenetic Therapy vs. Chemotherapy: What’s the Difference?
While chemotherapy targets all rapidly dividing cells, epigenetic therapy focuses on the epigenetic changes that control gene expression. This makes epigenetic therapy more precise, with the potential to reverse the changes that caused the cancer in the first place. Chemotherapy, on the other hand, kills both cancerous and healthy cells, which often leads to more severe side effects.
Eligibility for Epigenetic Therapy
Not all patients are eligible for epigenetic therapy. It is typically recommended for patients with specific types of cancers, particularly blood cancers or cancers with known epigenetic changes. Genetic and epigenetic testing may be required to determine if a patient is a good candidate for this treatment.
How to Prepare for Epigenetic Therapy in India
Before starting epigenetic therapy, patients must undergo a series of evaluations, including blood tests and genetic testing, to assess their cancer’s specific mutations. This helps doctors tailor the treatment plan to the patient’s unique genetic and epigenetic profile.
Top Hospitals Offering Epigenetic Therapy in India
India is home to several world-renowned cancer treatment centers offering epigenetic therapy. Tata Memorial Hospital in Mumbai is one of the leading institutions providing cutting-edge cancer treatments, including epigenetic therapies. AIIMS in Delhi and Apollo Cancer Centres across multiple cities also offer advanced epigenetic therapies as part of their oncology programs.
Cost of Epigenetic Therapy in India
The cost of epigenetic therapy in India varies depending on the type of cancer, the specific drug used, and the hospital. On average, the cost ranges from ₹2 lakh to ₹8 lakh per treatment cycle. Although costly, epigenetic therapy in India is significantly more affordable compared to Western countries, making it a viable option for many patients.
Success Rates of Epigenetic Therapy
Epigenetic therapy has shown promising results, particularly in treating blood cancers like acute myeloid leukemia and myelodysplastic syndromes. Success rates vary depending on the type of cancer and its specific genetic and epigenetic makeup. While ongoing research is expanding the use of epigenetic therapy for solid tumors, it has already proven to be a valuable tool in the fight against certain blood cancers.
Future of Epigenetic Therapy
Epigenetic therapy is still a relatively new field, but ongoing research is showing great promise. Scientists are exploring how to combine epigenetic therapy with other treatments, such as immunotherapy, to improve outcomes for patients with a broader range of cancers. The future of epigenetic therapy looks bright, with new drugs being developed to target additional epigenetic mechanisms and expand its use to more cancer types.
