Biological Therapy

The body’s immune system gets stimulation to fight cancer cells from some biological therapies. The cancer cells do not become the direct target of these types of biological therapy, also sometimes collectively called ‘immunotherapy’. The cancer cells become the direct target of the other biological therapies such as monoclonal antibodies. Some biological therapies, also referred to as targeted therapies, interfere with the molecules involved in the growth of tumours. In the biological therapy for cancer treatment in Kolkata, there is the use of living organisms, substances derived from living organisms or laboratory-produced versions of such substances. An oncologist uses biological therapies to treat cancer or the side effects of other cancer treatments in cancer patients.

Types of biological therapy

For treating cancer, oncologist doctors in Kolkata use several types of biological therapies, especially immunotherapies. There are different ways in which these therapies fight cancer.

  • Immune Checkpoint Inhibitors. In the treatment of various cancer types including bladder cancer, head and neck cancer, liver cancer, skin cancer and stomach cancer, immune checkpoint inhibitors are used.
  • Immune Cell Therapy. It is also known as Adoptive Cell Therapy or Adoptive Immunotherapy. There are two approaches in this therapy, known as Tumour-infiltrating lymphocytes (TILs) and CAR T-cell therapy. In the treatment of metastatic melanoma, oncologists use Adoptive T-cell transfer. There is also the use of two CAR T-cell therapies by the top 10 cancer specialist doctors in Kolkata in the treatment of some adults and children with acute lymphoblastic leukaemia and some adults with certain types of B-cell non-Hodgkin lymphoma).
  • Therapeutic Antibodies. In the treatment of a wide variety of cancers, oncologists use many therapeutic antibodies.
  • Therapeutic Vaccines. The use of these vaccines is in the treatment of metastasized prostate cancer in men and some patients with metastatic melanoma.
  • Immune-Modulating Agents. Oncologists in Kolkata prefer the use of most immune-modulating agents to treat advanced cancer. As a part of a supportive care regimen, some of these agents are also used.
