The study is being conducted to evaluate the efficacy and safety of sintilimab in combination with reduction of cycles of chemotherapy (carboplatin and nab-paclitaxel) in patients with oral cavity or oropharyngeal squamous cell carcinoma who are about to undergo surgery. Data obtained in this trial will provide valuable information for planning further prospective clinical trials of anti-PD-1 and other immunotherapies in oral cavity or oropharyngeal squamous cell carcinoma.
Have a histologically confirmed diagnosis of OSCC or OPSCC which is planned for treatment with curative intent including surgical resection.

Has had another known invasive malignancy within the previous 5 years and/or has had surgery, chemotherapy, targeted small molecule therapy or radiation therapy within 5 years for a known malignancy prior to study day 0.
If subject received major surgery for any other reason, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of day -5.
