This study is being done in two stages. Participants are being invited to participate in stage 2. The purpose of stage 1 of the study was to find out how soon ctDNA disappears from blood in patients with lung cancer treated with pembrolizumab and whether ctDNA disappearance or continued detection related to how well people did. In stage 2 the study will use the blood tests to figure out if patients on treatment with pembrolizumab with ctDNA that is still detected in the blood after 6 weeks of pembrolizumab could do better by adding standard chemotherapy treatment before the cancer is worse compared to continuing on standard pembrolizumab without added chemotherapy.
