My mom is a non-smoker, 68y old, and she was recently diagnosed with stage IV lung cancer with brain and bones metastasis and both EGFR positive and PDL-1 positive (= 95%). Her encologist put her on 80mg Tagrisso/osimertinib daily and we are about to start the treatment. I have zero medical background and until this date, I never felt I had the desperate need to research and understand what could be the best thing we can do to fight this disease. I read a lot about my mom's condition and I understand it is not curable. I also understand that Tagrisso is a temporarily treatment until the body eventually gains resistance to it.
Following are some questions I would sincerely appreciate if someone can help me get answers to:
- Since mom's PDL is positive, is she eligible for immunotherapy? I read that this has shown great progress and better prognosis compared to TKI. When would her oncologist put her on this treatment?
- I booked an appointment with 2 alternative medicine doctors knowing in advance that these are not scientifically proven but since the medicine itself prescribed by the oncologist is not a cure, I want to maximise my mom's chances. both prescribed a intensive vitamins course + diet food (no meat, no dairy, mainly plant's based food). I showed the viatmins prescription to the oncologist and his advice was these are useless and better not to take them as "we do not know which interactions they might have with the treatment, if any". I am insisting and I want to have a clear cut answer. who can help me with this? I am happy to share the list.
Many thanks in advance
