This article presents a clinical case demonsratinga high metastatic potential of clear cell renal cell carcinoma combined with atypical metastases to breast and paranasal sinuses. The prevalence of metastatic lesions to the breast and paranasal sinuses in various malignant tumors depending on their morphological forms is analyzed. The authors present an analysis of data published for the last 30 years. The optimal diagnostic algorithms to detect the progression of renal cell carcinoma and to evaluate the effectiveness of the treatment are considered.

428 Background: About one-third of patients with clear cell renal cell carcinoma (ccRCC) exhibit metastasis at the time of diagnosis and show poor prognosis. The genetic and epigenetic alterations associated with metastasis in ccRCC have variably been studied, and their role in the metastatic process is unclear. The goals of the current study were to identify genomic copy number alterations (CNAs) associated with ccRCC metastasis and examine their clinical utility. Methods: In this IRB-approved study, genome-wide copy number profiling was performed on DNA from 144 ccRCC (81 primary and 63 metastatic lesions). Differential CNAs between primary and metastatic lesions and between different metastatic sites were identified using Fisher’s exact test. Associations between CNAs and overall survival (OS) were tested using the log rank statistic and Kaplan-Meier method. Genomic profiling data of 437 and 240 primary ccRCC (TCGA and PMID: 23797736, respecitively) were used for verification. Results: Between primary and metastatic lesions, 25 CNAs were significantly different (p<0.05). Of the 11 more frequent in metastatic lesions, nine retained significance when comparing stage IV and stage I TCGA ccRCC. For 368 TCGA locally-invasive tumors (stages I, II, and III), three CNAs (loss of 9p24.3-p13.3, 9p12-q11, and 9q21.12-q21.33) were associated with inferior survival (p=0.002). In the second dataset of 214 locally-invasive lesions, loss of 18q11.2-q23 correlated with shorter OS (p=0.025). Across metastatic lesions, nine CNAs were found to be significantly enriched in lung lesions and three in bone. In a subset of 127 ccRCC with known metastatic status at 5 years after diagnosis, two of these CNAs (gain of 7q36.1-36.3 in lung and loss of 22q13.2 in bone) were significantly enriched in the corresponding primary specimens. Conclusions: This study identified CNAs associated with ccRCC metastasis and common sites of metastasis that have the potential to serve as biomarkers to assist in better risk stratification of patients with this disease. Integrated analyses of genes mapping to the loci of genomic imbalance would further our understanding of the biology of metastasis in renal cancer.

Long non-coding RNAs (lncRNAs) play important roles during the initiation and progression of cancer. We identified DiGeorge Syndrome Critical Region Gene 5 (DGCR5) as a clear cell renal cell carcinoma (ccRCC) cancer- and lineage-specific lncRNA. Agarose gel electrophoresis analysis and sanger sequencing verified two main isoforms of DGCR5 in ccRCC patient tissues and cell lines. Quantitative polymerase chain reaction further demonstrated that the expression level of DGCR5 major isoform (isoform-1) was higher in ccRCC tissues than that in papillary/chromophobe RCC and other multiple solid malignant tumors. We investigate the biological functions of DGCR5 isoform-1 in ccRCC and show that DGCR5 isoform-1 exerts a tumor-promoting effect in ccRCC. DGCR5 isoform-1 is localized in cytoplasm and shares the same binding sequence to the tumor-suppressive miR-211-5p with the epithelial-to-mesenchymal transition key component SNAI. Furthermore, cellular and molecular experiments demonstrate that DGCR5 isoform-1 could sequester miR-211-5p, leading to the elevation of Snail protein and downregulation of its downstream targets and further promoting ccRCC cell proliferation and migration. Thus, our study indicates that DGCR5 isoform-1 could contribute to ccRCC progression by sponging miR-211-5p through regulating the expression of Snail protein and could serve as a reliable diagnostic biomarker in ccRCC.

105 Background: Tumor-associated macrophages (TAMs) are one of the key contributors to the tumor microenvironment and are phenotypically differentiated into M1 and M2 macrophages. M1 macrophages stimulate anti-tumor immune responses, whereas M2 macrophages promote immunosuppression and are associated with tumor progression in clear cell renal cell carcinoma (ccRCC). However, little information is available regarding the difference in TAM polarization between primary and metastatic lesions of ccRCC. Methods: We collected paired samples of primary and matched metastatic sites from the first recurrence in 41 metastatic ccRCC patients. Immunohistochemistry (IHC) for Iba1, which is a common pan-macrophage marker, and CD163 and CD204, which are considered to be M2 macrophage markers, was performed on all paired samples. Results: Thirty-three paired primary and metastatic samples were available for IHC assessment in this analysis. The most common metastatic sites were lung (N = 26, 78.8 %) and lymph node (N = 3, 9.1 %). The mean (± standard deviation) cell density of Iba1+ TAMs was higher in metastatic lesions than in primary lesions (756 ± 267 mm2 vs. 581 ± 155 mm2, P = 0.0012). By contrast, the ratio of CD163+ and CD204+ to Iba1+ TAMs was significantly lower in metastatic lesions than in primary lesions (0.76 ± 0.30 vs. 0.90 ± 0.24, P = 0.0067 and 0.39 ± 0.27 vs. 0.67 ± 0.29, P = 0.0001, respectively). The median overall survival of patients with high- vs. low-density Iba1+, CD163+, and CD204+ TAMs in metastatic lesions was 120 vs. 92 months (log-rank P = 0.67), 120 vs. 58 months (log-rank P = 0.056), and 120 vs. 92 months (log-rank P = 0.35), respectively. Conclusions: TAMs in the metastatic lesions of ccRCC polarized towards an M1-like phenotype, although the total number of TAMs was greater in metastatic compared with primary lesions. The cell density of Iba1+, CD163+, and CD204+ TAMs in metastatic sites was not associated with overall survival in patients with ccRCC.

Clear cell renal cell carcinoma (ccRCC) is the main type of RCC, which is the most common type of malignant kidney tumor in adults. A subpopulation (>30%) of ccRCC patients develop metastasis; however, the molecular mechanism remains largely unknown. Here, we found that LTF, the gene encoding lactotransferrin, is dramatically downregulated in primary tumors compared to normal tissues derived from ccRCC patients deposited in The Cancer Genome Atlas (TCGA) database and is a favorable prognostic marker. Moreover, LTF downregulation appears to be more dominant in metastatic ccRCC. LTF overexpression suppresses migration ability in A498 ccRCC cells with high metastatic potential, whereas LTF knockdown fosters cellular migration in poorly metastatic ccRCC cells. Gene set enrichment analysis demonstrated that LTF expression inversely correlates with the progression of epithelial-mesenchymal transition (EMT) in ccRCC, which was further confirmed by RT-PCR experiments. Therapeutically, the administration of recombinant LTF protein significantly suppresses the cell migration ability and lung metastatic potential of ACHN cells, as well as LTF-silenced A498 cells. The gene knockdown of lipoprotein receptor-related protein 1 (LRP1) robustly blocked recombinant LTF protein-induced inhibition of cellular migration and gene expression of EMT markers in ACHN cells. LTF downregulation and LRP1 upregulation combined predicted a poor overall survival rate in ccRCC patients compared to that with either factor alone. Our findings uncover a new mechanism by which LTF may interact with LRP1 to inhibit metastatic progression in ccRCC and also reveal the therapeutic value of recombinant LTF protein in treating metastatic ccRCC.
