TanıTedavi answer

Short answer: No. CAR-T cell therapy is not chemotherapy in the classical sense. CAR-T is a personalized cellular immunotherapy in which the patient's T cells are genetically modified and programmed to target cancer cells. Its mechanism differs from cytotoxic chemotherapy; it uses directly targeted immune cells. However, in some patients, short-term preparative chemotherapy may be administered before CAR-T to facilitate the enrollment of CAR-T cells. Hematology/hematologic oncology or transplant centers assess suitability for CAR-T and evaluate the risks/benefits. Individuals who have received or plan to receive CAR-T should seek immediate emergency medical attention if they develop a high fever, shortness of breath, fainting/altered consciousness, or seizure-like symptoms. This information is not a diagnostic or treatment recommendation; consult a hematologist for individual assessment and guidance.
