Patients must undergo endoscopic ultrasound (EUS), CT chest/abdomen/pelvis with IV/PO contrast (MRI abdomen/pelvis plus noncontrast chest CT is acceptable if patient has a contraindication to iodinated dye), and PET/CT to complete staging and confirm absence of metastatic disease.~3. HER2+ and HER2- patients, and all other known molecular subsets are eligible.~4. Diagnostic laparoscopy is not mandated and can be performed as clinically indicated.~5. Eligible for surgery with curative intent~6. A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies:~   1. Not a woman of childbearing potential (WOCBP) as defined in Appendix 3 OR~  2. A WOCBP who agrees to follow the contraceptive guidance in Appendix 3 during the treatment period and for at least 120 days after the last dose of study treatment.~7. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.~8. Measurable or non-measurable disease by RECIST 1.1 will be allowed.~9. Is willing to provide tissue for correlative studies from the primary tumor lesion at baseline and at time of surgery. Is willing to provide blood and stool samples for all ordered studies.~10. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to the date of allocation.~11. Have adequate organ function as defined in the following table (Table 1). Table 1 Adequate Organ Function Laboratory Values System Laboratory Value Hematological~    * Absolute neutrophil count (ANC) ≥1500/µL~   * Platelets ≥100 000/µL~   * Hemoglobin ≥9.0 g/dL or ≥5.6 mmol/La Renal~   * Creatinine OR Measured or calculatedb creatinine clearance (GFR can also be used in place of creatinine or CrCl) ≤1.5 × ULN OR ≥30 mL/min for participant with creatinine levels \>1.5 × institutional ULN Hepatic~   * Total bilirubin ≤1.5 ×ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels \>1.5 × ULN~   * AST (SGOT) and ALT (SGPT) ≤2.5 × ULN Coagulation~   * International normalized ratio (INR) OR prothrombin time (PT) Activated partial thromboplastin time (aPTT) ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants~ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase); AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase); GFR=glomerular filtration rate; ULN=upper limit of normal.~1. Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.~2. Creatinine clearance (CrCl) should be calculated per institutional standard. Note: This table includes eligibility-defining laboratory value requirements for treatment; laboratory value requirements should be adapted according to local regulations and guidelines for the administration of specific chemotherapies.~Exclusion Criteria:~* Participants are excluded from the study if any of the following criteria apply:~  1. A WOCBP who has a positive urine pregnancy test within 72 hours prior to allocation (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.~ 2. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX 40, CD137).~ 3. Previous or concurrent malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or any other cancer for which the patient has been previously treated and the lifetime recurrence risk is less than 30%.~ 4. Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to allocation.~     Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy may be eligible.~     Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.~ 5. Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.~ 6. Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.~ 7. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.~ 8. Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.~ 9. Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.~ 10. Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.~ 11. Has an active infection requiring systemic therapy.~ 12. Has a known history of Human Immunodeficiency Virus (HIV).~ 13. Has a known history of active TB (Bacillus Tuberculosis).~ 14. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.~ 15. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.~ 16. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment.~ 17. Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
