Understanding Immunotherapy & The Decision
Questions to Ask Before Starting Immunotherapy — A 20-Question Checklist
Before starting immunotherapy, ask about eligibility, biomarker results, realistic benefit, cost, treatment duration, and stopping rules — not just side effects. Most cancer patients in India are not automatically eligible for immunotherapy, so the first honest question is whether you qualify at all, confirmed by biomarker testing, not by hope alone.

- Ask eligibility first, benefit second — the honest opening question is whether your biomarker result even qualifies you, not how well it might work
- Bring this list, not just your memory — a printable 20-question checklist covering benefit, cost, duration and exit criteria so nothing gets missed in a short visit
- Ask about stopping rules before you start — how your team defines "working," how long treatment usually continues, and when they would recommend stopping
- A second opinion is a fair question to ask — if an answer feels rushed or unclear, requesting a written second opinion is reasonable, not distrustful

What are the most important questions to ask before starting immunotherapy?
The four questions that matter most are: am I actually eligible, based on my biomarker result; what benefit can I realistically expect; what will this cost and for how long; and what are the "stopping rules" — the signs that mean my team would change or end treatment. Every other question builds on these four.
Most cancer patients in India are not automatically eligible for immunotherapy — eligibility depends on a specific biomarker test, such as PD-L1 expression or MSI-High/dMMR status, and your exact cancer type, not on how advanced your disease is or how much you want it to work. Confirming this honestly, before anything else, is the single most useful thing this checklist can help you do. See Immunotherapy at CION Cancer Clinics for how eligibility is assessed.
A note on hope: it is normal to hope immunotherapy is your answer. It is also fair to ask a question that could produce a "not eligible" answer — a good oncologist welcomes that question rather than avoiding it.
Did you know?
Checkpoint inhibitor immunotherapy is approved as a treatment option in a still-limited list of cancers and biomarker groups. Outside that list, it generally is not offered — not because of cost or access, but because there isn't yet approved evidence that it helps. (Source: NCCN treatment guidelines, current as of 2025–26.)
The Printable Checklist
The 20 questions, grouped so you don't forget one
Print this, or note it on your phone, and work through each group with your oncologist in order.
Group 1 of 5
Eligibility & biomarker
- What test decides if I'm eligible — and what did it show?
- Is my cancer type and stage one where immunotherapy is approved?
- If I'm not eligible now, could that change later?
- Is a second biomarker test or opinion worth getting first?
Group 2 of 5
Benefit, honestly
- For someone with my exact diagnosis, what response rates are typically reported, and by which guideline body?
- Is the goal disease control, or is a longer remission realistic to discuss?
- How will we know if it's working — and by when?
- What happens if it doesn't work?
Group 3 of 5
Cost & duration
- Can I get a written cost estimate, not a verbal one, before we start?
- Roughly how many cycles or months are typically planned?
- Is biomarker testing itself billed separately?
- Does my insurance or Aarogyasri cover any part of this?
Group 4 of 5
Side effects & monitoring
- What are the early warning signs of an immune-related reaction?
- Is there a helpline number I should save right now?
- How often will I be monitored, and for what?
- Can these effects appear after treatment ends too?
Group 5 of 5
Stopping rules & next steps
- What result would make you recommend stopping?
- What happens after we stop — is there follow-up?
- If I want a second opinion, will that delay anything urgent?
- What does the honest worst case look like for my situation?
Cost & Duration
What should I specifically ask about cost and duration?
Ask for a written estimate covering the drug cost per cycle, the biomarker test cost, and roughly how many cycles are typically planned for your specific cancer and regimen — not a single headline number. Costs are indicative only, as of August 2026, and vary by hospital, regimen and how long treatment continues, so a written, case-specific estimate matters more than any figure found online.
Duration is decided case by case — some regimens run for a fixed, planned number of cycles, others continue as long as they are working and tolerated, up to a guideline-defined maximum. Ask which pattern applies to your case specifically.

Stopping Rules
What are "stopping rules," and why does this question matter so much?
Stopping rules are the specific, pre-agreed signs your oncology team watches for that would lead them to stop, pause, or change your immunotherapy — for example, disease progression on scans, a severe immune-related side effect, or reaching a guideline-defined maximum duration. Asking about them before you start means you're never caught off guard by a change in plan.
This question also protects you from false hope in the other direction: knowing in advance what "it isn't working" looks like, on paper, makes it easier to hear that news calmly if it ever comes, rather than feeling blindsided months in.
Using This Checklist
How do I actually use this checklist at my appointment?
Five steps to get through all 20 questions in one visit, without feeling rushed.
-
Bring every report you have
Pathology, imaging, and any biomarker test already done — even if the results feel incomplete.
-
Ask the eligibility question first
Get a direct yes, no, or "we need to test" before discussing anything else on the list.
-
Write down the answers as you go
Or bring someone who can, so you're not relying on memory once you're home.
-
Ask for the written estimate before you leave
Get the cost and duration figures in writing before you agree to start, not after.
-
Say so if an answer feels rushed
Asking for a second opinion at this stage is reasonable, not a delay tactic.

Second Opinions
Not sure the answers you got were complete?
Getting a second, doctor-led opinion before starting is a reasonable step, not a distrustful one. See getting a second opinion before starting immunotherapy.
Stage 4 Cancer
Been told immunotherapy is your only option?
It's worth understanding what it can, and cannot, realistically achieve at this stage. See immunotherapy for Stage 4 cancer: what it can and cannot achieve.
Side Effects
Worried about a specific side effect first?
Hair loss is one of the most common early questions patients ask. See will I lose my hair on immunotherapy?
If The Answer Is "Not Eligible"
What if the honest answer is "not eligible," and where does CION fit into this?
For many patients, the honest answer to the eligibility question is "not eligible" or "not yet" — and hearing that is disappointing, but it does not mean nothing can be done. Chemotherapy, targeted therapy, surgery, radiation, or a structured watch-and-wait plan may still be genuine, guideline-backed options depending on your exact cancer type and stage. For a smaller group of patients with advanced, widespread disease, an honest conversation may also include best supportive (palliative) care as a real option focused on comfort and quality of life — not a failure to treat. This is a decision for your oncology team and your family, not something any checklist can settle alone.
CION's tumour board reviews your diagnosis, biomarker results and overall fitness together before answering any of these questions — decisions for healing, not billing. For the fuller picture of how immunotherapy is assessed and monitored at CION, see Immunotherapy at CION Cancer Clinics.
This page is a preparation guide for the conversation with your oncologist — it is not medical advice and does not diagnose or recommend treatment for any individual. Response patterns and cost ranges mentioned here are general, guideline-sourced information (NCCN, ASCO), current as of August 2026, and can change.

Common questions
Questions to ask before immunotherapy — answered
What questions should I ask before starting immunotherapy?
Start with four: am I actually eligible, based on my biomarker result and cancer type; what benefit can I realistically expect; what will this cost and for how long; and what are the "stopping rules" — the specific signs that would make my team change or end treatment. Every other question, including side effects and monitoring, builds on these four. Most patients are not automatically eligible for immunotherapy, so confirming that honestly, first, is the most useful question of all.
What should I ask about cost and duration?
Ask for a written estimate — not a verbal one — covering the drug cost per cycle, biomarker testing costs, and roughly how many cycles are typically planned for your specific cancer and regimen. Costs are indicative only, as of August 2026, and vary by hospital, regimen, and how long treatment continues. Also ask whether duration is fixed at a set number of cycles or continues as long as it's working, since the two patterns are decided very differently.
What are "stopping rules," and why should I ask about them?
Stopping rules are the specific, pre-agreed signs your oncology team watches for that would lead them to stop, pause, or change your treatment — for example, disease progression on scans, a severe immune-related side effect, or reaching a guideline-defined maximum duration. Asking about them before you start means a change in plan, if it happens, won't come as a shock. It also protects you from false hope by making clear, in advance, what "it isn't working" would actually look like.
Am I likely to be eligible for immunotherapy at all?
Most cancer patients in India are not automatically eligible. Eligibility usually depends on a specific biomarker test result — such as PD-L1 expression or MSI-High/dMMR status — and your exact cancer type and stage, not on how advanced your disease is or how much you hope it will work. Some autoimmune conditions, long-term steroid use, or a prior organ transplant can also rule it out. Only biomarker testing and your oncology team's review can confirm eligibility for your specific case.
Should I bring someone with me to ask these questions?
Yes, if possible. Bringing a family member or caregiver to write down answers, ask follow-up questions, or simply help you remember what was said is genuinely useful — many patients find it hard to absorb everything in a single visit, especially early in a diagnosis. If you're the one researching on someone else's behalf, bring this checklist and their reports together so the appointment covers all four core questions in one visit.
What if my oncologist doesn't have time to answer all of these?
A rushed answer to a question this important is a fair reason to ask for a longer appointment or a second opinion — that isn't distrustful, it's reasonable. CION's consultations are structured for 45 minutes specifically so questions like these can be worked through properly, and a written second opinion is available if you want another doctor-led view before deciding.
