Could a drug cocktail boost survival in early oral cancer?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with early oral squamous cell carcinoma diagnosed as T1-2N0M0 according to the eighth edition of AJCC TNM stage; * No history of other malignant tumors; * 18-75 years old; * Baseline inspection is normal: 1. The absolute value of neutrophil (ANC) ≥1.5x109/L in the past 14 days without the use of granulocyte colony-stimulating factor; 2. Platelets ≥100×109/L without blood transfusion in the past 14 days; 3. Hemoglobin \>9g/dL in the last 14 days without blood transfusion or use of erythropoietin; 4. Total bilirubin ≤1.5× upper limit of normal (ULN); 5. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) in ≤2.5×ULN (patients with liver metastases allowed ALT or AST ≤5×ULN); 6. Serum creatinine ≤1.5×ULN and creatinine clearance (calculated by Cockcroft-Gault formula) ≥60 ml/min; 7. Good coagulation function, defined as International standardized ratio (INR) or prothrombin time (PT) ≤1.5 times ULN; 8. Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. If baseline TSH is outside the normal range, subjects with total T3 (or FT3) and FT4 within the normal range can also be enrolled; 9. The myocardial enzyme profile is within the normal range (if the researchers comprehensively judge that the simple laboratory abnormality is not clinically significant, it is also allowed to enter the group); 10. For female subjects of reproductive age, a urine or serum pregnancy test should be performed within 3 days prior to receiving the first study drug administration (day 1 of cycle 1) and the result is negative. If the urine pregnancy test results cannot be confirmed as negative, a blood pregnancy test is requested. Women of non-reproductive age were defined as at least one year after menopause or having undergone surgical sterilization or hysterectomy; 11. If there is a risk of conception, all subjects (male or female) are required to use contraception with an annual failure rate of less than 1% for the entire duration of treatment up to 120 days after the last study drug administration (or 180 days after the last chemotherapy drug administration). Exclusion Criteria: * Other malignant tumors are diagnosed, or oral cancer is not the beginning of neoadjuvant therapy; * An active autoimmune disease requiring systemic treatment (e.g. use of disease-modifying drugs, glucocorticoids, or immunosuppressants) has occurred within 2 years prior to treatment. Replacement therapies (such as thyroxine, insulin, or physiologic glucocorticoids for adrenal or pituitary insufficiency) are not considered systemic therapy; * known allogeneic organ transplantation (other than corneal transplantation) or allogeneic hematopoietic stem cell transplantation; * Known history of human immunodeficiency virus (HIV) infection (i.e. HIV 1/2 antibody positive); * untreated active hepatitis B (defined as HBsAg positive and HBV-DNA copy number detected greater than the upper limit of normal value in the laboratory of the study center); Note: Hepatitis B subjects who meet the following criteria can also be enrolled: 1. HBV viral load \<1000 copies /ml (200 IU/ml) before initial dosing, subjects should receive anti-HBV therapy throughout study treatment to avoid viral reactivation; 2. For subjects with anti-HBC (+), HBsAg (-), anti-HBS (-) and HBV viral load (-), prophylactic anti-HBV therapy is not required, but close monitoring of viral reactivation is required; * active HCV-infected subjects (HCV antibody positive and HCV-RNA levels above the lower limit of detection); * Pregnant or lactating women; * The presence of any serious or uncontrolled systemic disease, such as: 1\) The resting electrocardiogram has major abnormal rhythm, conduction or morphology, such as complete left bundle branch block, heart block above Ⅱ degree, ventricular arrhythmia or atrial fibrillation; 2) Unstable angina pectoris, congestive heart failure, New York Heart Association (NYHA) grade ≥ 2 chronic heart failure;
