A glioblastoma diagnosis in India: a survivor's journey

When I was diagnosed with a Grade 4 glioblastoma in October 2023, at the age of 30, I had to piece together a lot on my own. This is a short account of my journey and the things that mattered most early on — written for other patients and caregivers in India who are going through it now - not medical advice.

How it unfolded

August 2023 — the first signs

It began with numbness in my left fingertips that faded after a few weeks. Then came severe headaches, and slowly, a very subtle reduction in my left-hand function — typing, fastening my bra strap. It was a really busy time at work, and I just ascribed it all to stress for a few months.

October 2023 — the scan

Eventually, when one day I started struggling to hold a fork straight while eating, I knew matters were deteriorating fast, and I finally saw a neurologist on the 30th of October. On examination he could see less than a 5% difference between my left and right sides — but he ordered an MRI with contrast anyway, just to be sure. It showed a tumour on my right parietal lobe. They suspected a glioma straight away, likely high-grade, from the imaging.

November 2023 — surgery

We immediately went to see a neurosurgeon, who agreed with the preliminary diagnosis and recommended immediate surgery with no separate biopsy. We also ran a full eye exam in parallel to check my vision hadn't been affected. On the 4th of November I had a five-hour awake craniotomy, and a large part of the tumour was removed. Three paraffin blocks of tumour tissue were stored for further testing.

Pathology confirmed a Grade 4 glioblastoma, IDH-wildtype. Methylation profiling came back MGMT-positive (methylated), which meant I would benefit more from the temozolomide chemotherapy.

One thing I would do differently: I should have had a post-surgical MRI within 72 hours of the operation. It was not suggested to me, and that early scan is an important baseline to separate the true picture from tumour remnants versus post-surgical changes like inflammation that might set in thereafter.

In parallel — molecular testing

We sent the stored tumour blocks to one Indian lab (MedGenome) and one international lab for NGS testing, to see whether my tumour carried any specific mutations that might respond to targeted therapies. Results took about four weeks. Mine came back "immunologically cold" — no additional approved drugs would help, since mine lacked any of those specific markers.

From late November 2023 — standard treatment

Within about four weeks of surgery, I started on standard of care (SOC): six weeks of radiation with low-dose temozolomide alongside it, followed by adjuvant chemotherapy. Under close oversight from my oncologist, I was recommended 13 cycles of chemotherapy over 15 months rather than the usual six, and for three of those cycles I was recommended to add lomustine to the temozolomide, based on a small German study suggesting a survival benefit in methylated tumours.

From the start of radiation I moved to a gluten-free, dairy-free, sugar-free diet under a senior nutritionist experienced with GBM patients. My energy stayed high — I was walking close to 10,000 steps a day even through radiation.

2024 — options beyond standard care

Along with SOC, my oncologist mentioned some international options if I could find the resources, since some are exceptionally expensive. One was Optune Gio, a wearable device approved in the US for over a decade and now available across parts of Europe. I started it in May 2024 and still use it — it needs at least 18 hours a day to show positive results, and you have to keep shaving your head every 3–4 days so the device stays in close contact with your skin. It's hard to adjust to at first, but the survival benefit is clear and the side-effects are minimal, so I decided it was worth all the effort.

I also began an experimental personalised peptide vaccine from CeGaT/CeCaVa in Germany, which needed my tumour block and blood samples. I started in September 2024 and continue with follow-on doses, as it's showing a positive immune response. Both options meant significant international travel. With my savings and my family's support, I was fortunate to be able to access these treatments.

Now — more than 2.5 years on

It's been more than two and a half years, and I've been living as close to a normal life as I could hope for. I work from the office in person, do regular strength training to rebuild the muscle I lost during chemotherapy, practise breathing exercises for my mental wellbeing, and keep to a clean gluten-free, dairy-free diet with several natural supplements to support a healthy lifestyle.

A glioblastoma diagnosis was not necessarily the end of the road — with a positive and strong mind, there was definitely a way to fight the prognosis and achieve better outcomes.

What I'd tell someone starting out

01
Don't explain away subtle changes
Paying attention to small changes in your body — a weak hand, odd numbness, new headaches — deserves medical attention. Don't brush it away.
02
Make sure your tumour tissue is stored
Ask the surgical and pathology team to retain paraffin blocks of your tumour. Almost everything that comes later — molecular testing, NGS, even access to several clinical trials and experimental treatment options — depends on having that tissue.
03
Ask for a post-op MRI within 72 hours
This is the one thing I'd change. An early scan confirms how much was removed and sets the baseline for every scan that follows. Hospital protocols may differ, so confirm this with your team before surgery — don't assume it will be done.
04
Get the molecular picture early
MGMT methylation and IDH status shape your treatment, and NGS testing tells you whether any targeted options exist for your specific tumour. Ask which tests are being done and what the results mean for you. Even a "nothing actionable" answer is worth knowing. There are several centres carrying out these tests — the ones I mentioned above are just some options that were recommended to me.
05
Look after the body that has to get through this
Working with a nutritionist who understood GBM, staying active, and rebuilding strength afterwards kept my energy and my life intact. These were my personal choices alongside standard treatment, not replacements for it — but they mattered enormously to how I felt day to day. A quick tip for the radiation phase: hair loss can start at random, and at different times for different patients. I'd ideally have shaved my head at the outset, rather than seeing big clumps of hair fall out — that can be quite mentally distressing.
06
Know that options beyond standard care exist — even though they are very costly
Optune and the CeGaT vaccine are real, evidence-backed options, but they meant international travel and significant expense. If you might want to explore them, see whether you can access them through financial assistance, or even through clinical trials that might provide that access.
07
You are allowed to hope
The statistics are frightening, and I won't pretend otherwise. There are several extremely challenging and frustrating days. But more than two and a half years on, I'm working, training, and focusing on living fully — and the chance to do that is worth fighting for.

Questions I'm asked most

These are the questions caregivers and patients write to me most often, gathered in one place. They're based on my own experience — not medical advice. Take anything useful here to your own neurosurgeon and neuro-oncologist; every glioblastoma is different.

For patients who have not yet had surgery

What should I discuss with my neurosurgeon before the operation?

These were both options I was not presented with, and in retrospect I would have liked the chance to discuss them. Two things are worth raising before surgery, as they depend on choices made during the operation:

Dendritic cell (DC) vaccines. These use your own immune cells and typically require tumour tissue to be preserved in a specific way during the resection surgery itself — so it's important to raise this in advance. In India, DenVax is one such dendritic cell vaccine option you can ask about.

5-ALA guided surgery. 5-ALA is a substance that makes tumour tissue fluoresce under special light during the operation, helping the surgeon distinguish tumour from healthy brain and achieve a more complete removal. Ask your neurosurgeon whether it's available and appropriate for your case.

Did you have a biopsy?

I was not advised a separate biopsy — the tumour sample was taken during my surgery itself. In some cases, depending on the tumour's location, size, and other factors, a separate biopsy may be advised. You can check with your neurosurgeon on this.

After surgery, before radiation

What should I ask about radiotherapy?

It's worth asking your radiation oncologist about the choice between photon and proton radiotherapy, and which is more suitable for your situation.

It's also worth asking what side effects to expect. These can range widely — from fatigue and severe acne (from the heat of the radiation) to, in my case, severe constipation, brought on by the six-week regimen combining an anti-nausea medication with concomitant temozolomide. Each of these can be addressed, but it's better to anticipate them in advance.

Lifestyle and nutrition

What did you do beyond medical treatment?

I followed a personalised, nutritionist-guided diet throughout, alongside some natural supplements. For nutrition, I'd suggest working with a qualified nutritionist who can tailor a plan to the individual.

I also found it important to keep up regular exercise including strength training, breathing exercises, and keeping stress under control.

The CeGaT personalised peptide vaccine

What is it?

It's a personalised neoantigen peptide vaccine made by CeGaT in Tübingen, Germany. They sequence your tumour tissue to design a vaccine specific to you, then manufacture it. It requires a tumour sample from surgery and a blood sample.

Standard radiation and chemotherapy can continue while it's being prepared. The published real-world results are in Latzer et al., Nature Communications (2024): nature.com/articles/s41467-024-51315-8

How long does preparation take?

Roughly four to five months from start to first dose. Genetic sequencing of the tumour sample takes about a month; once you confirm you want to proceed, vaccine production takes a further few months.

How many doses and trips are involved?

There are 14 vaccinations in total, which work out to about 11 trips. On the first visit, four priming doses are given over 4–5 days; each subsequent visit administers one shot.

Visits start every 4–6 weeks and, with a positive immune response, the interval can stretch to two or three months. The full course runs over roughly 1.5 years.

How much does it cost?

Approximately 70,000–80,000 euros for the vaccine programme itself. Travel and accommodation are completely additional, so budget for those separately.

Can I get it in India?

No. Because it's an experimental treatment it can't be shipped out and must be administered on site. The vaccine is produced in Tübingen, Germany.

A partner clinic in Vilnius, Lithuania offers the same approach and quality — sequencing and peptide synthesis are done in Germany, while administration happens in Vilnius.

How do I start the process?

You'll need a referral from your oncologist to the programme, then some paperwork. After they receive your tumour tissue and blood sample, they run the analysis and, once you confirm, begin manufacturing. Tumour tissue can be shipped via a courier such as DHL or FedEx.

Are there side effects? Does age matter?

I haven't experienced side effects myself, and age isn't considered a major factor for the vaccine.

This is broadly consistent with the published data: in the Latzer et al. study, adverse events were infrequent and predominantly mild (grade 1 or 2).

Do I need a special visa?

The visa type is the same as a standard tourist visa. We included the letter from the centre in the application to make the case for a two-year multiple-entry visa, which helps given the number of trips.

Other immunotherapy options

Are there other immunotherapy centres?

Another centre some patients explore is IOZK in Cologne, Germany, which offers its own immunotherapy approach. I have no personal experience with it, but it's worth discussing with your oncologist as an option to research.

There are also premier institutes within India, such as Tata, that may be working on innovative new treatments. It's worth checking with your doctors about any options that might be available for you.

Optune — Tumour Treating Fields

What is it, and how did you access it?

Optune is a wearable device. I was prescribed it through a doctor in London. To show a positive effect it needs to be worn for at least 18 hours a day.

It's worn more or less continuously, and the arrays need changing every 3–4 days, depending on how the individual's skin responds. Most caregivers manage this and get used to it after a few times; no nurse is needed.

More detail is on the official Optune Gio site: optunegio.com

How much does it cost?

It is very expensive — around £20,000 per month.

Please read this. Everything above is my own experience and the things I personally learned along the way. It is not medical advice, and it is not a treatment plan. Every glioblastoma is different, and every decision here should be made with your own neurosurgeon, neuro-oncologist, and treating team. Treatments, drug approvals, and costs also change over time. If anything here is useful, take it to your doctors and ask them about it — that's exactly what I hope you'll do.
