Brief Summary:
This phase Ib/II trial studies the side effects and best way to give pembrolizumab with combination chemotherapy and radiation therapy before surgery and to see how well it works in treating adult patients with gastroesophageal junction or gastric cardia cancer that has spread from where it started to nearby tissue and can be removed by surgery. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving pembrolizumab, combination chemotherapy, and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Primary Outcome Measures :
  1. Pathological complete response (PathCR) rate [ Time Frame: Up to 3 years ]
    Defined as number of patients with pathologic complete responses divided by total evaluable patients.

  2. Progression-free survival (PFS) rate (if Phase Ib is re-initiated) [ Time Frame: At 1 year ]
    PFS rate defined as the number of patients who are alive and progression-free at 1 year divided by the total evaluable number of patients.


Secondary Outcome Measures :
  1. Complete resection with no tumor within 1 mm of the resection margins (R0) rate [ Time Frame: Up to 3 years ]
    Defined as the number of patients who achieve R0 resection divided by total number of evaluable patients.

  2. Disease-free survival (DFS) [ Time Frame: Time from the date of study registration to the date of death due to all causes or recurrence, whichever occurs first, among patients who achieved an R0 resection, assessed up to 3 years ]
    The distribution of DFS will be estimated using the method of Kaplan-Meier. Two-year DFS rate and confidence interval will be estimated based on Kaplan-Meier curve.

  3. Incidence of dose-limiting toxicities assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: Up to 3 years ]
    The maximum grade for each type of adverse events that are possibly, probably or definitely related to study treatments will be recorded for each patient. The frequency tables will be reviewed to determine the patterns.

  4. Incidence of surgical complications [ Time Frame: Up to 3 years ]
    Incidence of surgical complications will be assessed.

  5. Overall survival (OS) [ Time Frame: Time from the date of study registration to the date of death due to all causes, assessed up to 3 years ]
    The distribution of OS will be estimated using the method of Kaplan-Meier. Two-year OS rate and confidence interval will be estimated based on Kaplan-Meier curve.

  6. Pathological complete response (PathCR rate) (if Phase Ib is re-initiated) [ Time Frame: Up to 3 years ]
    Defined as number of patients with pathologic complete responses divided by total evaluable patients (only done as secondary endpoint for phase 1b re-initiated treatment regimen).

  7. Progression-free survival (PFS) [ Time Frame: Time from the date of study registration to the date of death due to all causes, recurrences if R0 resections are achieved, progression disease before undergoing surgery, or R1/R2 resection at surgery, whichever comes first, assessed up to 3 years ]
    The distribution of PFS will be estimated using the method of Kaplan-Meier. Two-year PFS rate and confidence interval will be estimated based on Kaplan-Meier curve. (PFS will be examined as a secondary endpoint only for the original phase 1b treatment regimen).

  8. Time to relapse (TTR) [ Time Frame: Time from the date of study registration to the date of 1st documented relapse/recurrence among patients who achieve R- resection, assessed up to 3 years ]
    The distribution of TTR will be estimated using the method of Kaplan-Meier. Two-year relapse-free rate and confidence interval will be estimated based on Kaplan-Meier curve.
