Hi, Colleen, First of all, I am pleased to hear that news of Merry isn't the worst although caregiving, for both the carer and the cared, isn't, of course, the best.

Second, here is an update, as requested. I am doing fine! I am very comfortable with my decision not to start targeted treatment (Tagrisso for EGFR mutation) until I become symptomatic or something of concern shows on the 3-month scans. The January CAP (chest/abdomen/pelvis) scan showed the usual slow growth of some lung nodules (out of the 20 to 30 lung nodules I have); the brain MRI was fine.

My key questions for others with multifocal lung cancer are:

(1) do you have any metastases beyond the lungs? (I really don't like lumping bilateral lung lesions with metastases to other locations such as lymph nodes or brain or bone etc etc. By definition, bilateral lung lesions are considered metastatic and, therefore, stage 4, but I just don't think bilateral lung lesions are in the same league.)

(2) Based on molecular testing, are you doing targeted therapy to treat the specific malignancy identified by the molecular testing?

I am eagerly awating results, due in October, of the Mayo Clinic clinical study of multifocal lung cancer; and I thank this forum for bringing it to my attention.
