    Abstract: Purpose: This study aims to construct the stromal immunotype, which could improve the prediction of postsurgical survival and adjuvant platinum-based chemotherapy in muscle-invasive bladder cancer (MIBC). Experimental Design: A total of 118 patients with MIBC from Shanghai Cancer Center, 140 patients with MIBC from Zhongshan Hospital, and 287 patients with MIBC from TCGA cohort were included in the study. Immune cell infiltration was evaluated by IHC staining or CIBERSORT method. Five immune features were selected out of 22 immune features to construct immunotypes based on the LASSO Cox regression model. Results: Using the LASSO model, we classified patients with MIBC into stromal immunotype A subgroup (CTLhighNKhighTreglowMacrophagelowMClow) and stromal immunotype B subgroup (CTLlowNKlowTreghighMacrophagehighMChigh). Significant differences were found between immunotype A and immunotype B in the combined cohort with 5-year overall survival (OS, 76.0% vs. 44.0%; P & lt; 0.001) and 5-year disease-free survival (DFS, 62.8% vs. 48.3%; P & lt; 0.001). Stromal immunotype was revealed to be an independent prognostic indicator in multivariate analysis in all cohorts separately. Either OS or DFS was not improved by adjuvant chemotherapy (ACT) in pT2 stage patients or pT3+pT4 patients, but further analysis revealed that OS and disease-free was significantly improved by ACT in pT3+pT4 patients (P = 0.016 and P = 0.006, respectively). Finally, stromal immunotype A showed higher immune checkpoint molecules (PD-L1, PD-1, and CTLA-4) expression. Conclusions: The stromal immunotypes could effectively predict survival and recurrence of MIBC. Furthermore, the immunotypes might be a practical predictive tool to identify pT3+pT4 patients who would benefit from ACT. Clin Cancer Res; 24(13); 3069–78. ©2018 AACR.

    Overexpression of RCC2 Enhances Cell Motility and Promotes Tumor Metastasis in Lung Adenocarcinoma by Inducing Epithelial–Mesenchymal Transition
    American Association for Cancer Research (AACR) ; 2017

    Abstract: Purpose: Investigate the role of regulator of chromosome condensation 2 (RCC2) on lung adenocarcinoma (LUAD) metastasis. Experimental Design: Clinical specimens were used to assess the impact of RCC2 on LUAD metastasis. Mouse models, cytobiology, and molecular biology assays were performed to elucidate the function and underlying mechanisms of RCC2 in LUAD. Results: RCC2 expression was frequently increased in LUADs (88/122, 72.13%). It was confirmed by analysis of a larger cohort of TCGA RNA-seq data containing 488 LUADs and 58 normal lung tissues (P & lt; 0.001). Importantly, increased level of RCC2 was significantly associated with T status of tumor (P = 0.002), lymph node metastasis (P = 0.004), and advanced clinical stage (P = 0.001). Patients with LUAD with higher expression of RCC2 had shorter overall survival. Cox regression analysis demonstrated that RCC2 was an independent poorer prognostic factor for patients with LUAD. Moreover, forced expression of RCC2 promoted intrapulmonary metastasis in vivo and significantly enhanced LUAD cell migration, invasion, and proliferation in vitro. Further study found that RCC2 induced epithelial–mesenchymal transition (EMT) and also stimulated the expression of MMP-2 and MMP-9. In addition, RCC2 was able to activate JNK, while inhibition of JNK suppressed the effect of RCC2 on LUAD cell migration, invasion, EMT, and the expression of MMP-2 and MMP-9. Conclusions: RCC2 plays a pivotal role in LUAD metastasis by inducing EMT via activation of MAPK–JNK signaling. Clin Cancer Res; 23(18); 5598–610. ©2017 AACR.
