@divemaster I was diagnosed Stage 1b. No metastases. The protocol apparently is 3 years of Tagrisso. I’ll check with my oncologist this month, but I suspect there is clinical evidence that with low stage, cancer does not recur after 3 years of Tag. I also had a partial lobectomy and 4 chemo sessions over 12 weeks before starting Tagrisso. What stage was your wife at diagnosis?
