We saw a thoracic small cell specialist on Friday and Pop will start Chemotherapy with the 3 cocktail meds. They include : atezolizumab (Tecentriq), atopside (Toposar),and carboplatin (Paraplatin). He is treated with all on the first day, then less the other two days . He goes back in 3 weeks for 4 sessions. I would love to hear from anyone who has gone through small cell lung cancer which has metastasized.
