Brief Summary
The purpose of this study is to determine whether pembrolizumab, when given after salvage surgery, is effective in increasing the time a person with squamous cell cancer of the head and neck remains disease-free following locoregional disease recurrence.

Eligibility Criteria
You may qualify if:
- Has pathologically confirmed SCCHN (oral cavity, oropharynx, larynx, hypopharynx) with evidence of local and/or locoregional recurrence. Laryngeal tumors will only be included if there is evidence of extralaryngeal spread, or there is associated nodal disease. For all other sites, superficial tumors can only be included if there is associated nodal disease.
- Has a documented disease-free interval (minimum 16 weeks) after initial curative intent therapy.
- Candidate for salvage resection.
- Able to provide tissue from diagnostic core biopsy of tumor lesion(s).
- Patient has adequate organ function.
- Female patient of childbearing potential has a negative serum or urine pregnancy within 72 hours prior to receiving the first dose of study medication.
- Female patient of childbearing potential agrees to use adequate birth control.
- Male patient with a partner of childbearing potential agrees to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.
You may not qualify if:
- Patient has disease of nasopharyngeal carcinoma histology.
- Patient has evidence of metastatic disease.
- Patient is currently receiving or has received another investigational agent within 4 weeks prior to study Day 1.
- Patient has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of pembrolizumab.
- Patient has a known history of active TB (Bacillus Tuberculosis).
- Patient has received a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or baseline) from adverse events due to a previously administered agents.
- Patient has received prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1.
- Patients who have had major surgery or have insufficient recovery from surgical-related trauma or wound healing within 14 days from study Day 1.
- Patient has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
- Patient has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Note: Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
- Patient has an 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). Notes: (1) Patients with vitiligo, Grave's disease, or psoriasis not requiring systemic treatment within the past 2 years are not excluded. (2) Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Patient has a known history of, or any evidence of active, non-infectious pneumonitis.
- Patient receives chronic steroid use \> 10 mg prednisone (or steroid equivalent) daily.
- Patient is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial.
- Patient has received immunotherapy with inhibitors of PD-1 or PD-L1, or CTLA-4 blocking antibodies within 4 months prior to study Day 1.
