My husband is going through the same treatment for Upper Right Lobectomy EGFR Non Small Cell Lung Cancer. He has completed two rounds of your same chemotherapy, and is moving onto the Tagrisso. (Difficult reaction to chemo from aftermath of surgery related issues). Hoping to get him back on track with a new antibiotic today before starting Tagrisso. Thank you for your input on this support group. It helps to have all these complex issues explained. My best to you.
