Immunotherapy for Cancer in Delhi NCR
Immunotherapy for Cancer in Delhi NCR: A Comprehensive Overview
Today, cancer is still one of the leading causes of death in the world, with millions diagnosed every year. In recent years, the approach to treating cancer has changed dramatically from traditional approaches such as surgery, chemotherapy, and radiation to targeted and personalized therapies. Among these innovative treatments, immunotherapy has emerged as one of the most promising options for cancer patients, including those in the Delhi NCR area, which is home to some of India’s leading hospitals and healthcare institutions.
The identification of such cancer cells through a well-armed immune response or boosting the body’s innate capabilities to recognize cancer has brought immunotherapy as another exciting option in cancer management and treatment. The technique mainly targets cancerous cells compared to other traditional ways, which sometimes kill some other healthy cells too along with the disease-causing organisms.
The above article provides information on the concept of immunotherapy for cancer, types, advantages, challenges, and developments in immunotherapy research and treatment in Delhi NCR.
What is Immunotherapy?
Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancer. The immune system plays a crucial role in identifying and destroying harmful cells, including cancer cells. However, cancer cells can evade the immune system’s detection by producing signals that suppress immune responses or by forming an environment that prevents immune cells from attacking them. Immunotherapy aims to overcome these challenges by stimulating or enhancing the immune system’s natural ability to detect and destroy cancer cells.
Immunotherapy can be used alone or in combination with other cancer treatments, such as chemotherapy, radiation, or surgery. It has shown promise in treating various cancers, including melanoma, lung cancer, breast cancer, and lymphoma, among others. The treatment can be administered in several forms, such as intravenous infusion, oral medications, or local injections.
Types of Immunotherapy
There are several types of immunotherapies currently being used or researched for cancer treatment. Each type has a different mechanism of action, and the selection of the appropriate immunotherapy depends on the type of cancer, the patient’s health condition, and other factors.
1. Checkpoint Inhibitors:
• PD-1/PD-L1 Inhibitors: Programmed death protein 1 (PD-1) and its ligand PD-L1 are proteins that can suppress the immune system’s ability to fight cancer. Cancer cells can exploit this pathway to avoid immune detection. PD-1 inhibitors, such as pembrolizumab (Keytruda) and nivolumab (Opdivo), block this interaction and allow the immune system to target cancer cells more effectively.
• CTLA-4 Inhibitors: Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) is another immune checkpoint that cancer cells use to suppress immune responses. Ipilimumab (Yervoy) is an example of a CTLA-4 inhibitor. By blocking CTLA-4, ipilimumab enhances T-cell activation and immune response against cancer cells.
2. Monoclonal Antibodies:
Monoclonal antibodies are laboratory-made molecules designed to bind to specific antigens found on the surface of cancer cells. This binding can either mark the cancer cells for destruction by the immune system or block the cancer cells’ ability to grow and spread. Examples include trastuzumab (Herceptin) for breast cancer and rituximab (Rituxan) for certain types of lymphoma.
3. CAR-T Cell Therapy:
Chimeric antigen receptor T-cell (CAR-T) therapy is a groundbreaking treatment that involves modifying a patient’s T cells to express a receptor that specifically targets cancer cells. These modified T cells are then infused back into the patient, where they seek out and destroy cancer cells. CAR-T therapy has shown great promise in treating certain types of blood cancers, such as leukemia and lymphoma.
4. Cytokine Therapy:
Cytokines are proteins that help regulate immune responses. Some cancers can prevent the body from producing enough of the immune-boosting cytokines. Cytokine therapy involves using laboratory-made versions of these proteins, such as interleukin-2 (IL-2) or interferons, to stimulate the immune system and encourage it to attack cancer cells.
5. Cancer Vaccines:
Cancer vaccines are designed to stimulate the immune system to recognize and destroy cancer cells. Unlike vaccines for infectious diseases, cancer vaccines are personalized to target specific cancer antigens. The two main types of cancer vaccines are preventive vaccines (such as the HPV vaccine) and therapeutic vaccines that aim to treat existing cancers.
6. Oncolytic Virus Therapy:
This innovative therapy uses genetically modified viruses to selectively infect and kill cancer cells. The viruses can also stimulate an immune response against the tumor, making this approach both an antiviral and immunotherapeutic treatment.
