Hi Everyone,
I have been
a long-time reader of this amazing blog that Stephen created and regularly
check it for any posts about new treatments or therapies. I am really happy to
see that Stephen still occasionally posts new studies and answers some
questions.
I am quite
urgently seeking advice on next steps in relation to treatment for my partner
(of 18 years), who is a very physically active person and despite everything that has occurred, remains very positive. She is 40 years old.
Background:
We are based
in Australia and she was diagnosed in December 2011 (2 days before Christmas!)
with a low grade Astrocytoma in the left Temporal Lobe.
2012 (February): She underwent craniotomy
that resulted in a subtotal resection – it was an awake craniotomy owing to the
tumour’s location near important speech areas.
Histopathology
of the sample was unfortunately not very detailed and only confirmed a Low
Grade Astrocytoma with a very low KI67 of < 1%
2015 (February): The lesion increased in
size over the years (pretty much doubled) to 55 x 34 x 49mm – so a second
surgery was performed that again resulted in subtotal resection.
Histopathology
results showed – Low Grade Astrocytoma, IDH1 Mutated.
A
retrospective FoundationOne profile was obtained on this sample in 2017 and
only showed 2 mutations: IDH1 (R132H) mutated and TP53 (R175H).
2017 (September): The tumour continued to
grow and extended into the frontotemporal region and insula. Another Surgery
was conducted in two sessions due to expected length, and a large portion of
tumour from the temporal and frontotemporal regions was removed, as well as a
small portion from the insula.
Histopathology
results showed – IDH1, 1p/19q co-deletion, ATRX lost, TP53 Mutated, KI67 of 2%
A Caris
profile was also obtained which also showed that the tumour was not MGMT
methylated – although after asking Stephen about this at the time, he said that
MGMT was a bit of a hit and miss due to the heterogeneity found in tumours – so
we remained hopeful that MGMT may still be methylated in most of the tumour given
it is typical of low grade gliomas.
* The Caris
report conflicted with the histopathology and showed ATRX intact.
2018 (January): Managed to get Bayer to
sponsor my partner to take part in their IDH1 Inhibitor trial (BAY1436032),
went to L.A and got knocked down at the last minute due to not completely
satisfying their RANO requirements!
(September)
Sought out the top neurooncologist + radio oncologist team in Sydney and she
started IMRT then moved on to a round of TMZ which finished in early 2019.
2019 : MRI’s showed decent shrinkage in
the tumour volume for the first 6 months then stable.
2020 (January) : MRI showed slight
enhancement in the original temporal lobe resection cavity + strangely an
enhancing nodule on the right ventricle. These were determined by the neuro and
radio oncologists to be late radiation treatment effect and thought that they
would resolve.
(Late February)
MRI showed the enhancing nodule in right ventricle shrinking a bit, but
enhancing area in temporal lobe cavity growing a bit. Still determined to be
late treatment effect.
(June) : MRI
– ALL HELL HAS BROKEN LOOSE. There are now another 3 large enhancing lesions –
one in the right Frontal lobe, with a small one behind it, one in the Left
ventricle (looks like a cherry sitting on the ventricle wall) and a much larger
enhancement of in the original temporal resection cavity.
Needle
Biopsy – a needle
biopsy has just (yesterday) been performed on the right frontal lesion to get a
better understanding of the makeup of the new lesions. We are currently awaiting
the results and will also hopefully be getting a Caris or FoundationOne genetic
testing on the sample.
The surgeon mentioned that he could already see an increase in size since her last last (less that 1 week prior). So this is a very fast growing tumour/s.
Proposed Initial
Treatment
Her neuro-oncologist and radio-oncologist have suggested that she begin (as soon as possible) with CCNU + Procarbazine – and possibly Avastin for the swelling.
Current Medications (all anti-epileptics):
- Epilim (Sodium valproate)
- Fycompa (Perampanel)
- Lamictal (Lamotrigine)
- Briviact (Brivaracetam)
- Frisium (Clobazam)
Suggestions
I would be
extremely grateful if anyone can:
- provide
their thoughts on the proposed treatment
- make any
other treatment suggestions
- suggest anything
that could possibly increase the effectiveness of the
suggested treatment
suggested treatment
- point out
any pitfalls or things to be aware/weary of whilst on the treatment
- suggest
any promising potential trials or treatments anywhere in the world
- suggest
any cokctails that they have used with this treatment that have
resulted in better outcomes + better tolerability
resulted in better outcomes + better tolerability
The rapid
change from a fairly stable low grade astrocytoma really did catch us (and her doctors)
off-guard and I would be very appreciative of any advice or suggestions that
anyone could kindly offer.
Thanks to
you all.
Ryan.
New Note:
Just today my partner was told that she has extremely low levels of Vitamin D. Strangely enough, she has been really craving oily fish for the last 3 months and has been eating smoked trout and smoked salmon almost daily - obviously not enough to build up sufficient levels. The 3 month craving of Vitamin D strangely coincided with the new lesions showing up and their extremely fast growth.
I wonder if dramatically increasing her Vitamin D level may slow the progression? She has started taking 4000 IU and intends to keep it up every day.
Can anyone comment on this level of Vitamin D, would you up it even further? And are there any caveats with regards to Vitamin D supplementation.
Also, it there a particular way to rapidly raise the levels in the blood?
