Targeted Therapy is a cutting-edge cancer treatment that focuses on targeting specific molecules involved in the growth and spread of cancer cells. By honing in on these molecular targets, targeted therapies offer a more precise and effective approach to cancer treatment compared to traditional chemotherapy. In this guide, we will explore how targeted therapy works, its benefits, and the top hospitals in India offering this treatment.
What is Targeted Therapy?
Targeted Therapy is a form of cancer treatment that uses drugs or other substances to identify and attack specific cancer cells while minimizing damage to normal cells. It works by focusing on specific molecules involved in cancer cell growth, division, and spread.
How Does Targeted Therapy Work?
Targeted therapy works by interfering with the specific proteins or genes that control cancer cell growth and survival. Some targeted therapies block signals that tell cancer cells to grow, while others deliver toxic substances directly to the cancer cells, leading to their destruction.
Types of Targeted Therapy
There are different types of targeted therapy, each designed to attack cancer cells in a unique way:
- Monoclonal Antibodies: These drugs attach to specific proteins on the surface of cancer cells, marking them for destruction by the immune system.
- Tyrosine Kinase Inhibitors (TKIs): These drugs block the signals that cancer cells use to grow and divide.
- Angiogenesis Inhibitors: These drugs prevent the formation of new blood vessels that supply nutrients to tumors, effectively starving the cancer cells.
Which Cancers Can Be Treated with Targeted Therapy?
Targeted therapy is effective for treating a wide range of cancers, particularly those that are driven by specific genetic mutations. Some of the cancers that respond well to targeted therapy include:
- Breast Cancer: HER2-positive breast cancers can be treated with targeted therapies like trastuzumab (Herceptin).
- Lung Cancer: Non-small cell lung cancer (NSCLC) with specific mutations can be treated with TKIs.
- Colorectal Cancer: Certain colorectal cancers with mutations in genes like KRAS or BRAF respond well to targeted therapies.
- Leukemia: Chronic myeloid leukemia (CML) and other blood cancers can be treated with targeted drugs that block abnormal proteins.
1. How does Targeted Therapy work for liver cancer treatment?
Targeted therapy for liver cancer focuses on molecular pathways that help cancer cells grow. Drugs like Sorafenib, Lenvatinib, and Regorafenib inhibit proteins like VEGFR and RAF kinase, blocking tumor growth and blood vessel formation.
Sorafenib is the first-line treatment for advanced liver cancer when surgery isn’t possible. Lenvatinib offers another option, while Regorafenib is used after Sorafenib. Unlike chemotherapy, targeted therapy is more precise, minimizing damage to healthy cells.
Common side effects include high blood pressure, skin rashes, and fatigue, while the treatment extends survival by months or more.
Advantages of Targeted Therapy in Cancer Treatment
Targeted therapy offers several key advantages over traditional treatments:
- Precision: It targets specific molecules in cancer cells, leaving normal cells largely unaffected.
- Fewer Side Effects: Because it is more focused, targeted therapy often causes fewer side effects than chemotherapy.
- Combination Therapy: Targeted therapy can be used alongside chemotherapy, radiation, or surgery to improve treatment outcomes.
Side Effects of Targeted Therapy
Although targeted therapy is generally well-tolerated, it can still cause some side effects. Common side effects include:
- Fatigue
- Diarrhea
- Skin rashes
- Increased risk of infection
These side effects are typically less severe than those associated with chemotherapy, but they should still be closely monitored by your medical team.
Targeted Therapy vs. Chemotherapy: What's the Difference?
While chemotherapy attacks all rapidly dividing cells, including healthy ones, targeted therapy focuses on specific molecules that are only present in cancer cells. This precision makes targeted therapy less toxic and more effective in treating certain types of cancer. However, chemotherapy may still be used in combination with targeted therapy for a more comprehensive approach.
Eligibility for Targeted Therapy
Not all patients are eligible for targeted therapy. It is typically recommended for patients whose cancers have specific genetic mutations or abnormalities that can be targeted by the treatment. Genetic testing is often required to determine whether a patient is a good candidate for targeted therapy.
How to Prepare for Targeted Therapy in India
Before starting targeted therapy, patients need to undergo several tests, including blood tests and genetic testing, to determine whether their cancer has the specific mutations targeted by the drugs. Your oncologist will also review your overall health to ensure that you are a suitable candidate for the treatment.
Top Hospitals Offering Targeted Therapy in India
India is home to some of the most advanced cancer treatment centers, offering targeted therapy for various types of cancers. Tata Memorial Hospital in Mumbai is one of the leading institutions providing cutting-edge cancer care. Fortis Memorial Research Institute in Gurgaon and Apollo Cancer Centres across India are also renowned for their advanced oncology treatments, including targeted therapy.
Cost of Targeted Therapy in India
The cost of targeted therapy in India varies depending on the type of cancer, the specific drug used, and the hospital. On average, the cost ranges from ₹1 lakh to ₹5 lakh per treatment cycle. While expensive, this is significantly lower than the cost of targeted therapies in Western countries.
Success Rates of Targeted Therapy
Targeted therapy has shown impressive success rates in treating cancers with specific genetic mutations. For example, in patients with HER2-positive breast cancer or EGFR-mutant lung cancer, targeted therapies have significantly improved survival rates and quality of life. However, the success of the treatment depends on the type of cancer, the genetic mutation, and the patient’s overall health.
Future of Targeted Therapy
Targeted therapy is evolving rapidly, with ongoing research focusing on expanding its use to more types of cancer and improving the effectiveness of existing treatments. The future of targeted therapy looks promising, with new drugs being developed to target additional genetic mutations and innovative combinations of therapies being explored to enhance treatment outcomes.
