Criteria

Inclusion Criteria:

1. Patients aged ≥18 years;

2. The ECOG score is 0-1, and the ECOG score of amputation patients can be widened to 2, indicating good organ function;

3. Histologically determined CSCC with lymph node metastases or distal metastases (class 1) or locally advanced CSCC inoperable/unable to undergo radical radiotherapy (class 2).

4. Measurable tumor lesions were assessed by ultrasonography or CT within 21 days before enrollment;

5. Estimated survival time ≥3 months.

6. Primary tumor site Description: squamous cell carcinoma with primary labial mucosa can be included. Patients with primary SCC in the anogenital region (large and small labia, penis, scrotum, and perianal region) were excluded. The primary site was the nose, and patients were enrolled only if the investigator could definitively identify the primary site as the skin and not the nasal mucosa extending outward into the skin.

7. Category 2 only: Cases in which the investigator considers surgery inappropriate include: 1. Recurrent CSCC at the same location after two or more surgical operations and unable to undergo radical resection; 2. Local infiltration of CSCC made complete resection impossible; 3. The location of CSCC lesions is special and the operation is difficult, which may lead to severe defects or dysfunction (such as removing all or part of the facial structure, nose or eye, or requiring amputation); 4. Cases that are not suitable for surgical treatment for other reasons.

8. Category 2 only: At least one of the following criteria must be met if the investigator deems radiotherapy inappropriate: 1. The subject has received CSCC radiation therapy such that further radiation therapy would exceed the threshold for acceptable cumulative dose; 2. Subjects were intolerant to radiotherapy; 3. The subject is unwilling to participate in radiotherapy; 4. Cases in which radiotherapy is not suitable for other reasons.

9. Tumor histology: Patients with mixed histology (e.g., sarcomatoid carcinoma, adenosquamous carcinoma) are generally not eligible for enrollment. Only when the mixed histology type is mainly mixed basal cell carcinoma and invasive CSCC is the main histological component, the patients can be enrolled after communication with the investigator and approval.

10. There was at least one measurable lesion (no previous radiotherapy) according to the response evaluation Criteria for solid tumors, version 1.1 (RECIST V1.1). For nonbody surface lesions, accurate measurement by computed tomography (CT) or magnetic resonance imaging (MRI) (intravenous contrast medium is preferred) at baseline showed a long diameter ≥10 mm (except lymph nodes, whose short axis must be ≥15mm), and the lesions were suitable for repeated accurate measurement; For body surface lesions, calipers are required to accurately measure and show their long diameter ≥10 mm and clear lesion edge for repeated and accurate measurement. If the body surface lesions are deeply invasive lesions, CT or MRI is preferred for accurate measurement by referring to non-body surface lesions. A lesion located in a previously irradiated area clearly demonstrated progression that met the RECIST V1.1 criteria (surface lesions must be confirmed as disease progression by biopsy), then the lesion was considered measurable.

11. The subject shall consent to biopsy of the target lesion when the investigator deems it necessary for pathological confirmation.

12. Previous antitumor therapy was required to meet the following criteria: 1. The interval between systemic radiation therapy and the first dose of the study was ≥3 weeks, and the interval between local radiation therapy or bone metastases was ≥2 weeks. No dose of radiation was taken within 8 weeks before the first dose of this study; 2. The interval between previous chemotherapy and previous targeted therapy and the first administration of this study was ≥4 weeks, or ≥ 5 half-lives of the drug (whichever occurred first); 3. The interval between the first administration of immunotherapy, biologic therapy (tumor vaccine, cytokine or tumour-controlling growth factor), endocrine therapy, tumor embolization or other antitumor therapies including Chinese herbal therapy with antitumor indications was ≥4 weeks;

13. Having full organ and bone marrow function, as defined below:

14. Blood routine: absolute neutrophil count (ANC) ≥1.5×109/L; Platelet count (PLT) ≥90×109/L; Absolute white blood cell count (WBC) ≥3.0×109/L; Hemoglobin content (HGB) ≥90 g/L. Note: It is not recommended to use G-CSF, GM-CSF, red blood cell transfusion, platelet transfusion and other interventions to reach the normal range within 14 days before examination.

15. Liver function: total bilirubin (TBIL) ≤1.5× upper limit of normal (ULN); If TBIL > 1.5×ULN, binding bilirubin ≤ULN; For subjects with liver metastases or a history/suspicion of Gilbert's syndrome (persistent or recurrent hyperbilirubinemia, primarily unbound bilirubin hypertrophy, with no evidence of hemolysis or liver disease). TBIL acuities were 3 x ULN. Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≤2.5×ULN for subjects without liver metastases; For subjects with liver metastases, alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≤5×ULN.

16. Renal function: serum creatinine (Cr) ≤1.5×ULN, or creatinine clearance (CCr) ≥50 mL/min; 4) Adequate coagulation function, defined as prothrombin time (PT) and partially activated thrombin time (APTT) ≤1.5× upper limit of normal (ULN); If the subject was receiving anticoagulant therapy, the PT or INR was within the prescribed range for the anticoagulant.

17. Female subjects of childbearing age or male subjects whose sexual partners are women of childbearing age are required to use effective contraception throughout the treatment period and for 6 months after the end of treatment.

18. Signed a voluntary informed consent, understanding of the study and being willing to follow and able to complete all trial procedures.
