Collecting duct carcinoma of the kidney is associated with CDKN2A deletion and SLC family gene up-regulation. Oncotarget 2017; 7:29901-15.

Abstract
The genetic landscape and molecular features of collecting duct carcinoma (CDC) of the kidney remain largely unknown. Herein, we performed whole exome sequencing (WES) and transcriptome sequencing (RNASeq) on 7 CDC samples (CDC1 −7). Among the 7 samples, 4 samples with matched non-tumor tissue were used for copy number analysis by SNP array data. No recurrent somatic SNVs were observed except for MLL, which was found to be mutated (p.V297I and p.F407C) in 2 samples. We identified somatic SNVs in 14 other cancer census genes including: ATM, CREBBP, PRDM1, CBFB, FBXW7, IKZF1, KDR, KRAS, NACA, NF2, NUP98, SS18, TP53, and ZNF521. SNP array data identified a CDKN2A homozygous deletion in 3 samples and SNV analysis showed a non-sense mutation of the CDKN2A gene with unknown somatic status. To estimate the recurrent rate of CDKN2A abnormalities, we performed FISH screening of additional samples and confirmed the frequent loss (62.5%) of CDKN2A expression. Since cisplatin based therapy is the common treatment option for CDC, we investigated the expression of solute carrier (SLC) family transporters and found 45% alteration. In addition, SLC7A11 (cystine transporter, xCT), a cisplatin resistance associated gene, was found to be overexpressed in 4 out of 5 (80%) cases of CDC tumors tested, as compared to matched non-tumor tissue. In summary, our study provides a comprehensive genomic analysis of CDC and identifies potential pathways suitable for targeted therapies.

[PMID: 23773436 PMCID: PMC3728027 DOI: 10.1186/1746-1596-8-96] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2013] [Accepted: 05/06/2013] [Indexed: 01/09/2023] Open
Abstract
Objective To investigate the clinicopathological features of collecting duct carcinoma (CDC) and improve its diagnosis and treatment. Methods A retrospective analysis was performed with clinical data including follow-up results of five patients with CDC. Results A total of 5 cases, including 4 males and 1 female, were included in this analysis with the average age 54 years (range 42 to 65). Patients mainly suffered from lumbar pain, hematuria, abdominal mass and low grade fever. Four patients underwent radical nephrectomy while another received palliative nephrectomy. Lymph node metastasis occurred in 3 cases and renal hilum fat metastasis happened to 2 other cases. Tumors was located in the renal medulla and presented invasive growth. They had a tubulopapillary architecture with the hobnail-shaped cells protruding into the glandular lumen, and were accompanied by interstitial fibrosis and dysplasia of epithelial cells in collecting ducts adjacent to the tumors. One tumor was staged at AJCC II, two at AJCC III and two at AJCC IV. Postoperative interferon immunotherapy was applied in 2 cases. Patients were followed up for 5 to 18 months and the average survival time was 10 months. Conclusion The CDC exhibits special clinicopathological features, high degree of malignancy and poor prognosis. The diagnosis depends on the histopathological examination. Early detection and early surgical treatment are still the main methods to improve the prognosis of patients with CDC. Virtual Slides The virtual slide(s) for this article can be found here:
