Criteria

Inclusion Criteria:

1. Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.

2. Clinical diagnosis of oral cavity squamous cell cancer.

3. Patient can start study agent administration but histological confirmation of squamous cell cancer (SCC) of the oral cavity (or histologic variants of SCC) by the pathologist must happen within seven days of registration in order to continue protocol therapy.

4. Clinical stage II-IVA (as defined by the American Joint Committee on Cancer (AJCC), 8th Edition), and amenable to surgical resection.

5. New diagnosis of oral SCC, new second primary, or recurrent oral SCC following a minimum remission of six months following previous definite surgery.

6. History and physical examination by an otolaryngologist and medical oncologist within 14 calendar days of study registration.

7. Zubrod/ECOG Performance status < 2.

8. Age ≥ 18 years.

9. Complete Blood Count (CBC)/differential obtained within 14 calendar days prior to registration, with adequate bone marrow function defined as follows:

• Absolute neutrophil count (ANC) ≥ 1,500 cells/mm^3;

• Platelets ≥ 100,000 cells/mm3;

• Hemoglobin ≥ 8.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 8.0 g/dl is acceptable).

10. Adequate renal and hepatic function within 14 calendar days prior to registration, defined as follows:

• Serum creatinine < 1.5 mg/dl or creatinine clearance (CCr) ≥ 50 ml/min within 14 calendar days prior to registration, determined by 24-hour collection or estimated by Cockcroft-Gault formula:

• CCr male = [(140 - age) x (wt in kg)]

• [(Serum Cr mg/dl) x (72)]

• CCr female = 0.85 x (CrCl male)

11. Total bilirubin < 2 x the institutional upper limit of normal (ULN);

12. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 3 x the institutional ULN;

13. Magnesium, calcium, glucose, potassium, and sodium within 14 calendar days prior to registration, with the following required parameters:

• Magnesium: > 0.9 mg/dl or < 3 mg/dl;

• Calcium: > 7 mg/dl or < 12.5 mg/dl;

• Glucose: > 40 mg/dl or < 250 mg/dl;

• Potassium: > 3 mmol/L or < 6 mmol/L;

• Sodium: > 130 mmol/L or < 155 mmol/L.

14. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.

15. Female subjects must meet one of the following:

• Postmenopausal for at least one year before enrollment, OR

• Surgically sterile (i.e., undergone a hysterectomy or bilateral oophorectomy), OR

• If subject is of childbearing potential (defined as not satisfying either of the above two criteria), agrees to practice two acceptable methods of contraception (combination methods require use of two of the following: diaphragm with spermicide, cervical cap with spermicide, contraceptive sponge, male or female condom, hormonal contraceptive) from the time of signing of the informed consent form through 21days after the last dose of study agent, OR

• Agrees to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable contraception methods.)

16. Male subjects, even if surgically sterilized (i.e., status postvasectomy), must agree to one of the following:

• Practice effective barrier contraception during the entire study period and through 60 calendar days after the last dose of study agent, OR

• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception.)

17. Enrollment on an interventional postoperative study is allowed if study agents do not overlap.

18. Gastric tube drug administration is permissible.

Exclusion Criteria:

1. Pregnant or lactating women are ineligible due to unforeseeable risks to embryo or fetus.

2. Concurrent use of any medicinal botanical, natural, or other herbal compounds.

3. Planned subtotal or debulking surgery is not permissible.

4. Prior systemic chemotherapy for oral SCC; note that prior chemotherapy for a different cancer is allowable.

5. Prior radiotherapy for oral SCC is permissible if disease free for one year since prior oral cancer treatment and free of significant late radiation effects.

6. Severe active comorbidity, such as uncontrolled cardiac disease, infection, and severe chronic obstructive pulmonary disease (COPD).
