Hi all,
I was diagnosed in late September with a GBM (frontal, left, with large cyst, IDH1 mutated, MGMT unmethylated), which was subsequently successfully operated (gross total resection) at the end of September. I guess as many/most here, I eventually stumbled across Ben William's book, the Glioblastoma Treatment options guide and ultimately this invaluable blog and community, which I have been studying and following closely since. I recently concluded the first phase of my treatment, following standard Stupp Protocol (6 weeks concomitant RT/TMZ) and am currently planning next steps (plus waiting for first post-RT MRI next week...).
While I did not get 'smart' in time to save my tumor material from being paraffined post-OP (unbelievably, this is still standard practice here in Germany in most hospitals), I did actively supplement my first phase of treatment with what I think is a reasonably aggressive 'cocktail' approach, including the following components:
--------------------------------------------------------------------------------------
Meds:
- Chloroquine, 1x 250mg
- Celebrex, 2x 200mg
- Disulfiram, 1x 250mg - 500mg (+4mg copper)
- Sativex (THC/CBD spray), ca. 3-4 sprays (approx. 15-20mg)
In general, I tolerated these medications without any major problems or side effects, with a few exceptions. Notably, towards the end of the treatment I developed some peripheral neuropathy in my left foot, which has now almost recovered, however (took around 3-4 weeks to recover). Nevertheless, it cause me to cease the Chloroquine and Disulfiram shortly before the end of my RT treatment phase. In addition, I found it a little hard to tolerate Sativex as I wasn't too keen on the psychoactive effect, which gave me some anxiety / mild panic attacks from time to time at night. As a result, I took it only for around 3 weeks or so.
Supplements:
- Berberine: 1000mg
- Boswellia Serrata: up to 4400mg (gradually increased dosage over course of RT to protect from Edema)
- CBD oil (8%), 5 drops (started after ceasing to take Sativex)
- PSP, 2100mg
- Curcumin (Longvida), 2000mg, increased to 3000mg towards end of treatment
- Green Tea Extract, 3625mg
- Lycopene, 20mg
- Matiake D-Fraction Pro, 65mg (3x 23 drops)
- Melatonin, 20mg
- Omega 3 DHA/EPA, 3528mg
- Probiotics, ca. 40bn units
- Pterstilbene, 250mg
- Resveratrol, 500mg
- Selenium, 200ug
- Silymarin, 1500mg
- Soy extract, 3750mg
- Vitamin D, 9000IU
In general, all of the above were well tolerated without side effects. I'd also like to mention I was able to avoid any kind of Edema / Cortisone use during my RT therapy, which I believe may have been at least in part facilitated by Boswellia in combination with Celebrex.
Other:
- Ketogenic diet, max 40 g Carbs per day; generally constant medium to high Ketone bodies when measuring. Started 1 week before RT, and continued to last day
- Caloric restriction, lost ca. 8 kilos in 6.5 weeks of RT, which I think equates approx. 600kcal or so in daily caloric restriction
- Daily morning smoothie, with variety of hopefully beneficial things like berries, broccoli sprouts, spirulina, tumeric powder, Matcha green tea, cocoa powder, etc.
- Daily walks of ca. 1 hour to combat radiotherapy fatigue and keep fit
Ketogenic diet was somewhat difficult to maintain psychologically, but possible due to my partner's kind help in continuously seeking out new and often tasty dishes to keep things interesting. Caloric restriction much easier, since Temodal anyway caused me lack of appetite. I believe daily walks were very helpful to avoid RT fatigue, which affected me only in very minor way and much less than I expected.
--------------------------------------------------------------
NEXT STEPS & QUESTIONS
I am currently considering next steps, and having talked to various NOs and other Brain Tumor specialists, I am still not entirely convinced what the right way forward is. As expected, most doctors do not want to deviate from the Stupp Protocol (i.e. follow up the RT/TMZ phase with 6 months of 5/23 TMZ cycles). However, I am not convinced such a treatment would necessarily add much benefit in my case, since my tumor is MGMT unmethylated.
One of the leading specialists in Germany told me that the unmethylated MGMT status is irrelevant in the case of IDH1 mutated tumors like mine, since a study (NOA-4) showed that there was no significant difference in responsiveness between MGMT methylated or unmethylated IDH1 tumors.
https://www.ncbi.nlm.nih.gov/pubmed/19901110
However, upon further research I stumbled across the following interesting study from China, which seems to suggest that IDH1 mutated tumors might in fact be particularly resistant to TMZ (3-10x more resistant in cell culture test). The study also notes that in China they observed relatively little additional benefit of TMZ cycles for the IDH1 mutated group of patients compared to RT alone, and the authors argue that survival benefits for IDH1 mutated tumors may simply be the result of a less invasive / more benign type of tumor relative to wildtype. It makes me wonder if the fact that MGMT doesn't seemingly play as big a role for IDH1 mutated tumors is simply the result of the fact that neither responds well to TMZ...:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4747376/
I'm therefore a bit hesitant to simply go ahead with TMZ therapy hoping for the best, and would like to consider other options.
One approach I am considering is Immunotherapy at the IOZK clinic in Cologne, which is not far from my house. However, because I don't have frozen tumor material, they would have to make a personalized vaccine using a liquid biopsy approach. This, in turn, could make the treatment even more unproven than vaccines anyway are even when made from tumor lysate. An additional option which could possible materialize down the road (but not yet, as no trials are running here presently to my knowledge) is to try to get hold of an IDH1 vaccine on a compassionate use basis.
My immediate next step is to see the MRI results next week, but I'd be very grateful for any advice on how to proceed from here. Especially, I'd like to try and resolve the following questions:
1. Would it be unwise to not do any additional TMZ cycles? Are there any obvious chemotherapy alternatives perhaps?
2. Would the immunotherapy using liquid biopsy at IOZK clinic be a good alternative for ongoing chemotherapy cycles? Would it be advisable to start this right away (i.e. without any additional TMZ cycles), or should I do some TMZ cycles first just to hedge my bets?
3. Any other recommendations in terms of maintenance strategies. E.g. what medication(s) could make a good maintenance therapy, without concurrent chemotherapy?
Thanks in advance for any comments, and wish you all a very happy and most importantly healthy 2018!
Best,
John
