My mother 75yo, 5'2" 100lbs, non-smoker, non-alcohol, Asian, recently diagnosed with stage IV lung cancer Oct 2014. Has EGFR mutation. Difficulty breathing low energy. Lung and bone metastasis. She has been submitted to participate in TIGER-1 clinical trial to receive either Rociletinib or Terceva under randomization. No previous chemo, EGFR inhibitors.
Previous cancer: removed ovarian early 90's, removed cyst on kidney mid late 90's, thymoma in 2001 removed hypothalamus. Has arrhythmia, irregular heartbeat due to a faulty heart valve not sure atria or ventricular.
First treatment is tomorrow. Brain MRI shows no metastasis, PET scans show no other metastasis in other organs besides lung and certain bone sections (not sure which). Has been prescribed Zometa.
Medication: something for thyroid not sure what.
How long does my mother have to live? What is a probable progression scenario? What can I do to prepare my 79yo father? I know it "depends" and "no way to know for sure" qualifications. I live in Oregon. My sister lives in NY. My parents living together are in So Cal. We just found out a few weeks ago.
