Eligibility Criteria
Inclusion Criteria: Age ≥ 18 years. Patients must have had measurable stage III, measurable stage IVA, stage IVB (with or without measurable disease) or recurrent (with or without measurable disease) endometrial cancer. All patients were required to have histologic confirmation of the original primary tumor (submission of pathology report(s) is required). Patients with the following histologic types were eligible: endometrioid adenocarcinoma, serous adenocarcinoma, dedifferentiated/undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma. The patient may have received: 1) no prior chemotherapy for treatment of endometrial cancer, or 2) prior adjuvant chemotherapy for treatment of endometrial cancer(e.g., paclitaxel/carboplatin alone or as a component of concurrent chemotherapy and radiation therapy [with or without cisplatin]), or 3) prior radiation therapy for treatment of endometrial cancer. Prior radiation therapy may have included pelvic radiation therapy, extended field pelvic/para-aortic radiation therapy, intravaginal brachytherapy, and/or palliative radiation therapy, or 4) prior hormonal therapy for treatment of endometrial cancer. These must be stopped at least three weeks before the first date of study treatment. Recurrent or advanced endometrial cancer that is not suitable for local treatment, and advanced endometrial cancer that cannot tolerate radiotherapy. Prior antiangiogenic therapy is permitted. Recovering from the effects of recent radiation, surgery, or chemotherapy: if > 2 weeks before the study intervention, you may have previously received radiation with or without radiosensitizing chemotherapy. Participants had to recover from all radiation-related toxicity, no need to continue corticosteroid, and no radiation pneumonitis.

Exclusion Criteria: Known history of other malignancy (in the last 5 years) except localized tumors such as basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder carcinoma, cervical carcinoma in situ, breast carcinoma in situ that has undergone curative therapy and breast carcinoma that has not recurred for > 3 years after radical surgery Had received immunotherapy in the past, it includes immune checkpoint inhibitors (such as anti-PD-1 antibody, anti-PD-L1 antibody, anti-CTLA-4 antibody, etc.) , immune checkpoint agonists (such as ICOS, CD40, CD137, GITR, OX40 antibody, etc.) , immune cell therapy, etc. Such subjects may be admitted with the consent of the sponsor. 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. Previous history of immunodeficiency; HIV antibody positive; Current long-term use of systemic corticosteroids or other immunosuppressants Subjects who are known to have active pulmonary tuberculosis (TB) and are suspected to have active TB need to undergo clinical examination to exclude them; Known active syphilis infection. Known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation. Previous history of non-infectious pneumonia/interstitial lung disease requiring systemic glucocorticoid treatment or current presence of non-infectious pneumonia. Serious infections occur within 4 weeks before the first administration, including but not limited to comorbidities, sepsis, or severe pneumonia that require hospitalization; Active infections (excluding antiviral treatment for hepatitis B or C) that have received systemic anti-infective treatment within two weeks prior to the first administration. Untreated subjects with active hepatitis B (HBSAg positive and HBV-DNA above 1000 copies/ml (200 IU/ml) or above the lower limit of detection, whichever is higher), for subjects with Hepatitis B, anti-HBV therapy was required during study treatment; subjects with active hepatitis C (HCV antibody positive and HCV-RNA levels above the lower limit of detection) . Those who had a major surgical procedure or major trauma within 30 days before the first dose, or who had a major surgical plan within 30 days after the first dose (at the investigator's discretion); Minor local procedures (excluding central venous catheterization via peripheral venipuncture and implantable venous accessport) were performed within 3 days before the first dose.

Previous history of myocarditis, cardiomyopathy, and malignant arrhythmia. Unstable angina, myocardial infarction, congestive heart failure, or vascular disease requiring hospitalization (such as aortic aneurysm at risk of rupture), or other cardiac impairment (such as poorly controlled arrhythmias, myocardial ischemia) that may affect study drug safety evaluation within 12 months prior to first administration of study drug; A history of esophageal Gastric varices, severe ulcers, unhealed wounds, gastrointestinal perforation, abdominal fistula, tumor-related gastrointestinal obstruction, intra-abdominal abscess, or acute gastrointestinal bleeding in the 6 months before the first dose; Any arterial thromboembolic event, NCI CTCAE version 5.0 Grade 3 or higher, venous thromboembolism, transient cerebral ischemia, cerebrovascular accident, Hypertensive crisis, or hypertensive encephalopathy, occurred within 6 months before the first dose; Acute exacerbation of chronic obstructive pulmonary disease within 1 month of first dose Previous history of abdominal fistula or gastrointestinal perforation associated with anti-VEGF therapy; the imaging results revealed the invasion of intestinal wall by neoplasm during screening. During screening, imaging or clinical findings of gastrointestinal obstruction, including incomplete obstruction. Previous history of severe bleeding or coagulation disorders; during screening, imaging showed that the neoplasm surrounded major blood vessels or had obvious necrosis and cavitation, and the investigators believed that participation in the study might increase risk of bleeding. Toxicities from previous antitumour therapy did not resolve, defined as toxicities that did not return to grade 0 or 1 of NCI CTCAE version 5.0, or levels specified in the inclusion/exclusion criteria; Except for alopecia and sequelae of neurotoxicity related to previous platinum therapy. For subjects who develop irreversible toxicity and are not expected to worsen after administration of the study drug (EG, hearing loss), it may be included in the study after consultation with the medical examiner. Long-term radiation-induced toxicity in subjects who, in the judgment of the investigators, can not recover may be included in the study after consultation with the medical examiner.
