ObjectiveTo provide experimental proof for the specific immunotherapy in patients with renal cell carcinoma (RCC).MethodsThe expression of c-erbB-2 and HLA-A2 molecules in RCC were examined by flow cytometery and HLA-A2 cDNA RT-PCR.Tumor lysatic antigens (Tuly) was used to load DCs (DC-Tuly) to induce the generation of c-erbB-2 specific CTLs derived from peripheral blood mononuclear cells of RCC patients in vitro and CTLs was used to kill RCC cells which express or not express c-erbB-2 and HLA-A2.The cytotoxic activity of induced CTLs was further studied by antibodies (anti-c-erbB-2 and anti-CD 8) blocking assay.Resultsc-erbB-2 protein is tumor associated antigens for RCC.DC-Tuly induced specific CTLs highly killed c-erbB-2+ HLA-A2+ autologous and allogenic RCC,but non-specific ones lowly killed c-erbB-2- HLA-A2+ or c-erbB-2+ HLA-A2-RCC cells. The cytotoxic activity against tumor cells was blocked by anti-c-erbB-2 and anti-CD 8 monoclonal antibodies.ConclusionsThese results suggest that this specific CTLs adoptive immunotherapy for RCC patients with c-erbB-2+ HLA-A2+ could be a novel approach for clinical use.

Objective:To investigate the prognostic value of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI) before radiation in pancreatic cancer patients underwent radiation therapy. Methods:Clinical data of 61 patients with pathologically confirmed pancreatic cancer were retrospectirely analyzed. Query index values for each patient were clinically tested through electronic medical records. Overall survival (OS) data were collected through electronic medical records or telephone follow-up. Survival curves were compared using Kaplan-Meier methodology and log-rank test. Cox regression methodolo-gy was used for univariate analysis. Results:Using log-rank test and univariate regression analysis, we found that patients with lower NLR, PLR, CA19-9, increased PNI, and lower TNM-staging lived longer than those with increased NLR, PLR, CA19-9, lower PNI, and high-er TNM-staging, and that the difference was statistically significant. Through multivariate analysis, we found that NLR (P=0.029, OR 2.344, 95%CI:1.090-5.041) and PNI (P=0.026, OR 0.477, 95%CI:0.248-0.917) were independent predictors of OS in patients with pan-creatic cancer. Conclusion:NLR, PLR, and PNI are simple, effective, and reliable indicators for evaluating the prognosis of pancreatic cancer.
