BC nonresponse group. Immunohistochemistry was used to detect that PD-L1 expression and tumor angiogenesis-related proteins (VEGF and Semaphorin4D) in tissues from 124 patients with CREOC. The positive expressions of PD-L1, VEGF, and Semaphorin4D (SEMA4D) were found in 58.73, 50.79, and 71.43% of the 63 cases CREOC tissues with BC response, respectively, which were significantly higher than that in the 61 cases BC non-response group (< 0.05). PD-L1 expression correlated with SEMA4D and VEGF positively (= 0.344 and 0.363, < 0.001). Over-expressions of PD-L1, VEGF and SEMA4D are associated with more malignant clinicopathologic characteristics of CREOC Patients. In survival analysis, patients' response to BC was the independent factor for evaluation of PFS and overall survival (OS). Cell functional assays showed that Atezolizumab in combination with Bevacizumab inhibited the proliferation, migration, and invasion of cisplatin resistant ovarian cancer cell line A2780cis synergistically, which maybe associate with Bevacizumab suppressing the epithelial-mesenchymal transition (EMT) and PD-L1 expression by targeting STAT3. Furthermore, Bevacizumab and Atezolizumab induced synergistic anti-tumor effect and tumor growth Studies Female BALB/C nude mice were purchased from Charles River Japan (Tokyo, Japan). Animal experiments were approved by tianjin medical university cancer hospital and institute animal research committee and animals were maintained under specific pathogen-free conditions. To evaluate the effect of Bevacizumab and Atezolizumab on tumor growth, A2780cis cells (5 106) were injected subcutaneously into the right shoulders of syngeneic mice. One week later after injection, the graft tumor reached 9~10 mm2. And then, the mice were divided into 4 groups and there were six mice in each group. The treatment for each group was started and as follows: ? IgG mainly because control; ? Bevacizumab (5 mg/kg) every 48 h; ? Atezolizumab (10 mg/kg) every 48 h; ? Bevacizumab (5 mg/kg) + Atezolizumab (10 mg/kg) every 48 h. The treatment was performed every other day time and Mice were killed after treating for 3 weeks. Tumor size was determined every other day time and the volume of the tumor was estimated using the following method: Estimated tumor volume = size width (mm2). Statistical Analysis The spearman rank correlation and Mantel-Haenszel test were used to assess the degree of correlation among variables. The survival rate was determined by the Kaplan-Meier method, and the log rank test was used to determine significance.
