Cancer immunotherapy in India: types, suitability and planning

What is cancer immunotherapy?

The NCI describes immunotherapy as a type of biological therapy. The main types it lists are:

• Immune checkpoint inhibitors: drugs that block checkpoints, which normally stop immune responses from becoming too strong, so immune cells respond more strongly to cancer
• T-cell transfer therapy: immune cells are taken, changed or selected in a laboratory, grown in large numbers and returned to the body; CAR T-cell therapy is one form
• Monoclonal antibodies: laboratory-made proteins that bind to targets on cancer cells, some marking them for the immune system
• Treatment vaccines: vaccines that boost the immune response to cancer, unlike vaccines that prevent disease
• Immune system modulators: agents that enhance the body’s immune response

Who may be considered for immunotherapy?

The NCI notes that immunotherapy is used for many cancers but is not yet as widely used as surgery, chemotherapy or radiation. Whether it may help depends on the cancer type and stage and, for some drugs, on biomarker tests on the tumour. Some people receive immunotherapy alone and others with chemotherapy or other treatment. Your oncologist decides.

Which reports does an oncologist usually ask for?

Ask the hospital whether it needs:

• the histopathology report
• biomarker or molecular test results, if done
• staging scans with images
• a list of all previous cancer treatments and responses
• a history of autoimmune disease, such as thyroid or bowel conditions
• recent blood tests, including thyroid, liver and kidney function

How do I plan immunotherapy in India?

The NCI says immunotherapy is usually given in a clinic or hospital outpatient unit, most often into a vein, though some types are tablets, creams or given into the bladder. Treatment may be daily, weekly or monthly, sometimes in cycles. Checkpoint inhibitors can continue for a long time, so think carefully about where you will have ongoing doses.

The NCI explains that many side effects happen when the activated immune system also affects healthy tissues. Some can appear after you return home. Your doctors at home must know exactly which drug you received. Carry a treatment card or letter naming the drug and the treating team. Ask how scans will be used to check whether treatment is working and who will read them. T-cell therapies such as CAR T involve a more complex hospital process and longer stay. Ask the team to explain the full plan.

What should I ask the hospital before booking?

• Is immunotherapy suitable for my cancer, and do I need biomarker tests first?
• Which drug do you recommend and is it available in my country?
• How often will I need treatment and for how long?
• Which side effects should I watch for after I return home?
• Who will my home doctor contact if a side effect appears?
• How and when will you check whether it is working?
