CAR-T Cell Therapy

1. Treatment Overview

The Smart T Web Hospital, Gujarat's premier healthcare institution since 2012, proudly offers CAR-T Cell Therapy - one of the most advanced cancer treatment options available today. This groundbreaking immunotherapy represents a revolutionary approach to treating various blood cancers and certain solid tumors.

CAR-T Cell Therapy harnesses the power of a patient's own immune system by genetically modifying T-cells to better recognize and attack cancer cells. Our state-of-the-art facility and expert oncology team provide this cutting-edge treatment with the highest standards of safety and efficacy.

2. What is CAR-T Cell Therapy

2.1 Understanding CAR-T Cell Therapy

CAR-T Cell Therapy (Chimeric Antigen Receptor T-cell therapy) is a form of immunotherapy that uses a patient's own immune cells to fight cancer. The process involves:

• T-cell Collection: Harvesting T-cells from the patient's blood
• Genetic Modification: Engineering cells to express chimeric antigen receptors (CARs)
• Cell Expansion: Growing modified cells in laboratory conditions
• Infusion: Returning enhanced T-cells to the patient
• Cancer Fighting: Modified cells recognize and destroy cancer cells

2.2 How CAR-T Cells Work

The genetically modified T-cells are designed with special receptors that can:

• Recognize specific proteins on cancer cells
• Bind to cancer cells more effectively
• Activate immune responses against tumors
• Multiply and persist in the body
• Provide long-term cancer surveillance

2.3 Scientific Foundation

CAR-T Cell Therapy is based on decades of immunology research and represents the convergence of:

• Genetic engineering techniques
• Cell biology advancements
• Cancer immunology understanding
• Manufacturing process innovations
• Clinical trial outcomes
