My mother is a glioblastoma patient who was diagnosed in Sep 2017(IDH1 -ve, methylated). She had a complete resection and has completed her radiation. Following the radiation, we did 3 cycles of temozolomide and the following two cycles were Lomustine(CCNU)+Temozolomide, since I stumbled upon a research that the combination of the two results in a significant improvement in life expectancy for methylated cancers.
However, since this research had 6 cycles of lomustine+temozolimde after the radiotherapy, I wish to ask if I should go beyond the total 6 cycle mark for my mom to do a total of 9 cycles of chemotherapy? Has somebody gone through a situation like mine and gone beyond six cycles of chemo with lomustine and temozolomide in their protocol? Does more chemo always mean better survival? I've heard from my fellow caregivers that an increase consumption of CCNU+TMZ has a risk of liver failiure and pneumonitis, how true is that? If it is, is there anything that we can do to reduce the risk and still do this combination for a total of 9 cycles to get the benefit this protocol gives?
Some context: My mom's last MRI 2 months back showed no growth, her health stays decent, she tolerates the chemo well and her platelet/WBC/Hb/RBC stay around 100k+, 2.5k-3k, 12 and 3.7-4 respectively even during the CCNU+Temozolomide combination.
My mom also takes these supplements: Curcumin(4-5 g/day), Boswellia(4000 mg/day), Keppra(1000 mg/day), Quercetin(3000 mg per day), Resveratrol(400 mg/day) Bromelain(700 mg/Day), Celebrex(600 mg/day), Green Tea(400 mg/day), Ashwagandha(500 mg/day), Metformin 1500 mg day, Doxycycline/Mebendezole, Fish Oil(3-4g/day) and is on a ketogenic diet
I would love to hear from you guys!
