Tough question. I started out as limited small cell, only one lung nodule and several nearby lymph nodes.
I had Cisplatin and Etoposide for chemotherapy and 33 rounds of radiation to my chest. I have SIADH that came with the cancer that never went away so I knew it hadn’t worked. I convinced my doc to do another scan right away and viola, it’s now extensive. It cleared up the lung and metastinal nodes but now it’s in my spine and neck nodes. Now we’re trying Keytruda, an immunotherapy that hasn’t shown much promise for small cell. Most everyone I talk to has had it come back so that’s something to be prepared for. I’m just here working on my acceptance skills at this point. Praying the Keytruda doesn’t cause tooo many bad side effects. Welcome to the group and hugs all around.
