These therapies offer a more precise, effective, and often less toxic alternative for managing cancer.
At the GS Cancer Research Institute, recognized as the Best Radiation Cancer Hospital in Ghaziabad UP, patients have access to cutting-edge targeted therapies delivered by some of the Top Radiation Oncologist Doctors in Uttar Pradesh. This article provides an in-depth understanding of targeted cancer therapies, how they work, their benefits, and what to expect during treatment.
What are Targeted Cancer Therapies?
Targeted cancer therapies represent a revolutionary approach to cancer treatment, offering precision by focusing on the unique characteristics of cancer cells. Unlike traditional treatments such as chemotherapy, which can harm both cancerous and healthy cells, targeted therapies specifically attack cancer cells while sparing normal tissues.
Defining Targeted Therapies:
Targeted cancer therapies are advanced treatments designed to identify and combat specific molecules or genetic changes responsible for the growth and survival of cancer cells. These therapies provide a personalized approach, tailored to the molecular profile of each patient’s cancer.
How Targeted Cancer Therapies Work:
1. Targeting Genetic Mutations:
● Targeted therapies block mutations or alterations in specific genes that drive cancer cell proliferation.
● Example: Drugs like EGFR inhibitors or ALK inhibitors are used in cancers with these genetic mutations.
2. Inhibiting Tumor Growth Signals:
● Cancer cells often rely on specific signaling pathways to grow and divide uncontrollably.
● Targeted drugs disrupt these signals, preventing tumor growth and spreading.
● Example: HER2 inhibitors for HER2-positive breast cancer.
3. Preventing Angiogenesis:
● Tumors require a blood supply to grow and thrive.
● Anti-angiogenic drugs stop the formation of new blood vessels (angiogenesis) that feed tumors.
● Example: Bevacizumab (Avastin), which inhibits vascular endothelial growth factor (VEGF).
4. Boosting Immune Response:
● Some targeted therapies enhance the body’s immune system to recognize and destroy cancer cells.
● Example: Immune checkpoint inhibitors, like PD-1 or PD-L1 inhibitors, which unblock the immune system to fight cancer more effectively.
Types of Targeted Therapies:
Targeted therapies represent a cutting-edge approach in oncology, focusing on specific mechanisms that cancer cells use to grow and thrive. These therapies aim to attack cancer cells selectively, minimizing damage to healthy tissues. Below are the key types of targeted therapies and their applications in cancer treatment.
1. Monoclonal Antibodies:
Monoclonal antibodies are laboratory-engineered proteins designed to bind to specific targets on the surface of cancer cells.
● Mechanism of Action: These antibodies block signals that stimulate cancer growth, flag cancer cells for destruction by the immune system, or deliver toxic substances directly to cancer cells.
Examples:
● Trastuzumab (Herceptin): Used for HER2-positive breast cancer to inhibit tumor growth.
● Rituximab (Rituxan): Targets CD20 protein in certain types of non-Hodgkin's lymphoma.
● Benefits: Highly specific, reducing damage to healthy cells.
2. Small Molecule Inhibitors:
These drugs are small enough to enter cancer cells and disrupt the molecular pathways responsible for cancer growth and survival.
● Mechanism of Action: They block enzymes or proteins involved in cell signaling pathways that cancer cells rely on.
Examples:
● Imatinib (Gleevec): Used for chronic myeloid leukemia (CML) by targeting the BCR-ABL protein.
● Erlotinib (Tarceva): Targets EGFR mutations in non-small cell lung cancer.
● Advantages: Effective against cancers with specific genetic mutations or abnormal proteins.
3. Hormone Therapies:
Certain cancers depend on hormones to grow. Hormone therapies block or lower these hormones, halting cancer progression.
● Mechanism of Action: These therapies either reduce hormone levels or block their action on cancer cells.
Examples:
● Tamoxifen: Treats estrogen receptor-positive breast cancer by blocking estrogen receptors.
● Enzalutamide: Blocks androgen receptors in prostate cancer.
● Uses: Commonly used for hormone-sensitive cancers like breast and prostate cancer.
4. Immunotherapies:
Immunotherapies harness the power of the immune system to fight cancer by enhancing its ability to recognize and destroy cancer cells.
● Mechanism of Action: They block immune checkpoints or boost immune responses to cancer cells.
Examples:
● Pembrolizumab (Keytruda): An immune checkpoint inhibitor targeting PD-1 to activate T-cells against cancer.
● Ipilimumab (Yervoy): Targets CTLA-4 to enhance the immune response.
● Benefits: Effective for a wide range of cancers, including melanoma, lung, and bladder cancers.

The Role of Radiation Therapy in Targeted Treatments:
At the GS Cancer Research Institute, renowned as the Best Radiation Cancer Hospital in Garh, advanced radiation therapy is integrated with targeted treatments to optimize cancer care. By combining these therapies, doctors can achieve better tumor control while minimizing side effects. Radiation therapy plays a vital role in enhancing the precision and effectiveness of targeted treatments.
How Radiation Complements Targeted Therapy:
Radiation therapy and targeted therapy work synergistically to provide a comprehensive treatment approach. By targeting cancer cells on a molecular level with precision, radiation boosts the effectiveness of targeted drugs. Below are some ways in which radiation therapy enhances targeted treatments:
● Enhancing Effectiveness: Radiation therapy can sensitize cancer cells, making them more vulnerable to the effects of targeted therapy. This combined approach enhances the ability of targeted drugs to inhibit tumor growth and spread.
● Reducing Tumor Size: Radiation is often used to shrink tumors before or alongside targeted therapies, helping to reduce the size of the tumor. A smaller tumor allows for better-targeted drug delivery, ensuring that the drugs can effectively attack the cancer cells.
● Localized Treatment: One of the key advantages of radiation therapy is its precision. Radiation can be focused directly on the tumor, sparing surrounding healthy tissues. This localized treatment ensures that the targeted therapy can work more effectively, without causing excessive damage to nearby healthy cells.
● Targeting Resistant Tumors: Some tumors may become resistant to targeted therapies over time. Radiation therapy can be used to target resistant tumor cells, potentially overcoming this resistance and improving treatment outcomes.
● Enhanced Control over Tumor Growth: In some cases, radiation therapy is used as a complementary treatment after targeted therapy has reduced the size of the tumor. This helps to control tumor growth and prevent recurrence, offering a more comprehensive approach to treatment.
Types of Radiation Therapy Used in Combination with Targeted Therapy:
At GS Cancer Research Institute, we employ several types of radiation therapy that are carefully chosen based on the individual patient's needs and the characteristics of their cancer:
● External Beam Radiation: This method delivers high-energy radiation from outside the body to target the tumor with precision.
● Brachytherapy: In certain cancers, radioactive material is placed directly inside or near the tumor, allowing for a more localized and targeted approach.
● Proton Therapy: An advanced form of radiation that uses protons instead of x-rays to treat tumors, minimizing damage to surrounding healthy tissue.
