Inclusion Criteria

1. Age≥18 & ≤75.
2. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
3. Histologically or cytologically confirmed diagnosis of primary cervical squamous cell carcinoma.
4. According to the 2018 International Federation of Cervical Cancer Obstetrics and Gynecology (FIGO) staging standard, the patient was diagnosed in stage IB2-IIA2.
5. Has not received any treatment before.
6. Has at least one measurable lesion based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 assessed by investigator.
7. Has adequate organ function.

Exclusion Criteria

1. Has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

5. Pregnant or lactating female patients.
6. Drug or alcohol abuse.
7.

Arm && Interventions

Group	Intervention	Description
AK104	AK104	Patients will be treated with 1-4 cycles of neoadjuvant AK104. 2-4 weeks after the last cycle of neoadjuvant treatment, patients will undergo radical surgery.

Primary Outcome Measures

Name	Time	Method
Adverse Events (AEs)	Up to approximately 6 mouths	The number of participants experiencing an AE will be assessed. An AE is defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy.
Major pathological response (MPR) rate	within 14 working days after operation	MPR rate is defined as the percentage of participants having ≤ 10% viable tumor cells in the pathological examination of resected specimens.

Secondary Outcome Measures

Name	Time	Method
R0 resection rate	within 14 working days after operation	R0 resection rate is defined as the percentage of patients whose post-operative pathology indicate complete tumor resection with all margins being negative.
Objective response rates (ORR)	4-6 weeks after the first cycle of neoadjuvant treatment	ORR is the proportion of subjects with complete response(CR) or partial response(PR) , based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
Pathological Complete Response (pCR) rate	within 14 working days after operation	pCR rate is defined as the percentage of participants lacking of evidence of viable tumor cells in the pathological examination of resected specimens.
