PURPOSE The prognostic value of vascular endothelial growth factor (VEGF) protein, known to stimulate endothelial growth and angiogenesis, was evaluated in node-negative breast carcinoma (NNBC) and compared with established prognostic factors. PATIENTS AND METHODS In 525 consecutive patients with primary invasive NNBC (T1-2N0M0; tumor, node, metastasis stage), of whom 500 patients did not receive any systemic therapy, the cytosolic levels of VEGF165 were measured by using a quantitative enzyme-linked immunosorbent assay. The median follow-up was 46 months. Univariate and multivariate analyses were performed. RESULTS VEGF level was significantly inversely correlated with estrogen receptor (ER) positivity but positively associated with tumor size and histologic grade. Patients with VEGF levels above the median value (2.40 pg/microg of DNA) showed a significantly shorter survival time (P=.0012) than patients with levels less than the median value, also when analyzed as a continuous variable (P=.0277). Tumor size, grade, and ER expression were all statistically significant for overall survival in univariate analyses (P=.0069, P=.014, and P < .001, respectively). Multivariate analysis showed that VEGF level was the strongest predictor of overall survival (P=.0199). Histologic grade was also an independent predictor of survival (P=.0477). Among the 381 patients with ER-positive tumors, a group in general considered to have a good prognosis, we found a significant reduction in survival for those with levels of VEGF greater than the median value (P=.0009). CONCLUSION The results suggest that the level of VEGF165 protein is an independent, strong prognostic factor for survival in patients with NNBC, especially in the subgroup of patients with ER positivity. Thus, cytosolic VEGF165 might be useful to select patients for adjuvant systemic therapy.

Abstract Background Adenosine and its adenosine 2A receptors (A2AR) mediate the immunosuppressive mechanism by which tumors escape immunosurveillance and impede anti-tumor immunity within the tumor microenvironment. However, we do not know whether the adenosine pathway (CD39/CD73/A2AR) plays a role in renal cell carcinoma (RCC). Therefore, we studied the role of immunosuppression in RCC by assessing the adenosine pathway in patients with RCC treated with anti-vascular endothelial growth factor (anti-VEGF) agents or immune checkpoints inhibitors (ICIs) or both. Methods In 60 patients with metastatic RCC, we examined the expression of CD39, CD73, A2AR, and programmed cell death 1 ligand 1 (PD-L1) immunohistochemically in surgically resected tumor tissues and studied the clinicopathological characteristics of these patients. Patients were treated by cytoreductive nephrectomy with systemic therapy with anti-VEGF agent or a combination of the ICIs anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA4) antibody and programmed cell death 1 (PD-1) antibody. Results Increased expression of A2AR in the primary tumors was associated with metastatic profiles. Patients treated with anti–PD-1 antibody in monotherapy, a combination of anti-PD-1 and anti-CTLA4 antibodies, or anti-VEGF agents showed better response and longer overall survival if the primary tumor had higher PD-L1 expression and lower A2AR expression. In Cox multivariate regression analysis, higher expression of A2AR was associated with shorter overall survival. Conclusions Our findings suggest that the expression of A2AR and PD-L1 in the primary tumors in RCC might predict the outcomes of treatment with anti-VEGF agents and ICIs and that the A2AR pathway might be a molecular target for immunotherapy.

ObjectiveYKL-40 is a proangiogenic glycoprotein that is secreted by cancer cells and inflammatory cells. The expression of YKL-40 is induced by vascular endothelial growth factor inhibition. We tested the hypothesis that low baseline plasma YKL-40 is associated with improved outcomes in patients with ovarian cancer treated with bevacizumab.MethodsOne hundred forty patients with chemotherapy-refractory epithelian ovarian cancer were treated with single-agent bevacizumab 10 mg/kg every 3 weeks in a prospective trial. Plasma YKL-40 was determined by enzyme-linked immunosorbent assay before and during treatment. Both raw YKL-40 concentrations and age-corrected percentiles of normal YKL-40 level were used. Associations between plasma YKL-40 level and progression-free survival (PFS) and overall survival were tested using univariate and multivariate Cox proportional hazards models.ResultsBaseline plasma YKL-40 levels were higher in patients with poor performance status, less differentiated tumors, residual disease after primary surgery, higher than the median serum CA-125 level, and higher than the median serum vascular endothelial growth factor level. Age-corrected percentile of normal plasma YKL-40 greater than the lowest quartile (Q1, 85th percentile) was associated with shorter PFS in univariate (hazard ratio, 1.83; 95% confidence interval, 1.15–2.89; P = 0.010) and multivariate analyses and shorter overall survival in univariate analysis (hazard ratio, 1.96; 95% confidence interval, 1.27–3.03; P = 0.003). Increase in plasma YKL-40 during bevacizumab treatment, with correction for baseline plasma YKL-40, was a predictor of shorter PFS. Using normal versus elevated plasma YKL-40 as a cutoff did not provide the same discriminative value.ConclusionsLow plasma YKL-40 at baseline and during treatment is associated with improved outcomes in patients with chemotherapy-refractory advanced ovarian cancer treated with single-agent bevacizumab.
