This is an interventional treatment trial for Head and Neck Squamous Cell Cancer Read More

Inclusion Criteria:

1. Age (> 18 years old) and (< 70 years old) are acceptable for both men and women.
2. Understand the steps and contents of the experiment and sign the written informed consent voluntarily;
3. Histopathology was locally recurrent/metastatic squamous cell carcinoma of the head and neck.
4. In the past, at least one line of platinum-containing chemotherapy or combined with EGFR monoclonal antibody targeting therapy failed or relapsed. Definition of treatment failure: progress after chemotherapy or treatment after ecurrence/metastasis; progress within 6 months after concurrent radiotherapy and chemotherapy can be counted as first-line treatment; all treatment changes due to drug intolerance are not counted as treatment failure;
5. Agree to provide archived specimens of tumor tissue or fresh tissue (not necessarily tissue specimens);
6. ECOG score 0-2;
7. Expected survival of more than 3 months;
8. Computed tomography scans erformed within 28 days prior to the study should show that there is at least one clearly measurable tumor lesion in two vertical directions, the shortest diameter of which is greater than or equal to 1.0 cm (according to RESIST 1.1 standard).
9. Systematic chemotherapy and targeted therapy have been completed for at least 2 weeks before the study, and extensive/local palliative radiotherapy has been completed for at least 4 weeks.
10. Before the study, corticosteroids (prednisone > 10 mg/day or equivalent dose) were discontinued for at least two weeks.
11. Major operations requiring general anesthesia must have been completed for at least four weeks before drug use is studied; operations requiring local anesthesia/epidural anesthesia must have been completed for at least two weeks and the patient has recovered; skin biopsy requiring local anesthesia has been completed for at least one hour;
12. Previous antineoplastic biotherapies (cancer vaccines, cytokines or growth factors for tumour control) were completed for at least four weeks before the study.
13. Hemoglobin (> 90 g/L), neutrophils (> 1.0 *109/L) and platelets (> 80 *109/L) are required for routine blood tests (no blood transfusion or use of biological stimulating factors within 14 days prior to detection).
14. Serum creatinine (< 1.5 *ULN) or creatinine clearance (>50 mL/min) (Cockcroft-Gault formula);
15. Total bilirubin < 1.5 *ULN (Gilbert syndrome allows < 5 *ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.5 *ULN (patients with liver metastasis allow AST and/or ALT < 5 *ULN);
16. Thyroid function indicators: thyroid stimulating hormone (TSH), free thyroxine (FT3/FT4) in the normal range; if TSH is not in the normal range, FT3/FT4 in the normal range can be included in the group;
17. Adverse reactions caused by previous treatments recovered to grade 1 or below before admission (except for grade 2 neurotoxicity caused by alopecia and chemotherapeutic drugs).

18. Women who were confirmed not to be pregnant within 7 days prior to the study were required to agree to take medically approved effective contraceptive measures throughout the trial period and within 6 months after the end of the trial. 19. Patients can follow up on schedule, communicate well with researchers and complete the study in accordance with the research requirements.
