Eligibility Criteria

Inclusion Criteria

Participant must have pathologically or cytolofically confirmed (at MSK) esophageal, gastric, or gastroesophageal junction adenocarcinoma or squamous cell carcinoma

PD-L1-positive expression in >/=1% of the tumor or stromal cells. PD-L1 expression will be reviewed by MSK pathologist, scored and recorded using the combined positive score (CPS) formula (number of PD-L1 positive tumor cells, lymphocytes, and macrophages divided by the number of tumor cells x 100).

Participants must have disease that can be evaluated radiographically. This may be measurable disease or nonmeasurable disease according to RECIST 1.1.

Experimental Treatment

Group I: Cohort 2Experimental Treatment2 Interventions

25 participants may receive 370 MBq of 18F-BMS-986229 given intravenously and will undergo a single PET/CT scan 60 minutes (within the range of 55-70 minutes) postinjection. The scan itself is expected to last about 30 minutes and participants will be asked to remain in the waiting area or dedicated room for an additional 30 minutes post scan. The total time from injection will be 120 minutes. In both cohorts, participants whose treatment includes nivolumab and who have positive tumor localization observed at baseline will be asked to undergo an additional round of imaging. If the participant agrees, they will receive a second injection while undergoing nivolumab treatment (after at least 2 cycles or 6 weeksof therapy).

Group II: Cohort 1Experimental Treatment2 Interventions

10 participants will receive one injection of 18F-BMS-986229 (370 MBq) and will then undergo whole-body PET/CT (80 mA) encompassing the vertex of the skull to the proximal thigh performed at 60 minutes (within the range of 55-70 minutes) postinjection. The scan itself is expected to last about 30 minutes and participants will be asked to remain in the waiting area or dedicated room for an additional 30 minutes post scan. The total time from injection will be 120 minutes. In both cohorts, participants whose treatment includes nivolumab and who have positive tumor localization observed at baseline will be asked to undergo an additional round of imaging.
