Localized Pleural Metastases of Renal Cell Carcinoma After Nephrectomy: A Case Report and Literature Review

We herein report the case of a 61-year-old Japanese male with localized pleural metastases of renal cell carcinoma. The patient was admitted to our hospital because of dyspnea on exertion and left-sided pleural effusion. He had undergone right radical nephrectomy 10 years previously. Contrast-enhanced whole-body computed tomography revealed scattered nodular thickening of the left pleura with contrast enhancement and left-sided pleural effusion. Thoracoscopy performed under local anesthesia was applied to obtain a biopsy of the pleural nodules, and the specimen was consequently diagnosed as exhibiting pleural metastasis of renal cell carcinoma, clear cell type.

Tumor size has been used for decision making in the management of patients with renal masses. Active surveillance in selected patients is now increasingly common in tumors ≤4 cm in size. Clear cell renal cell carcinoma (CCRCC) is the most common type of renal malignancy. Adverse histopathologic characteristics that correlate with worse prognosis have been described in CCRCCs. The aim of our study was to determine the frequency and extent of adverse histopathologic characteristics in CCRCCs ≤4 cm and their association with patient outcome. A search of a single institution for nephrectomies performed for ...

Abstract Cytoreductive nephrectomy (CN) followed by systemic therapy had been considered the standard of care for metastatic renal cell carcinoma (mRCC) patients since two clinical trials established its role during the cytokines era. With introduction of new and effective drugs, such as vascular endothelial growth factor-targeted therapies, the role of CN started to be challenged. Retrospective studies conducted during the targeted therapy era pointed to better outcomes when CN was associated with systemic treatment, although certain patients with poor risk features did not seem to benefit. Therefore, prospective...

Abstract BACKGROUND: Renal cell carcinoma(RCC) is one of the most common malignancies in kidney, and usually leads to poor prognosis. Therefore, identifying novel biomarkers for predicting the progression and prognosis of RCC is essential. The purpose of this study is aimed to evaluate the function of miR-221-5p in RCC and the clinical value of miR-221-5p in RCC prognosis after surgery. MATERIALS AND METHODS: In our study, RT-qPCR, wound scratch assay, cell proliferation assay, transwell assay, and flow cytometry assay were performed to explore miR-221-5p expression level and its proliferation, migration and ...

Authors: Palumbo C, Mistretta FA, Knipper S, Mazzone E, Pecoraro A, Tian Z, Perrotte P, Antonelli A, Montorsi F, Shariat SF, Saad F, Simeone C, Briganti A, Lavallee LT, Karakiewicz PI Abstract BACKGROUND: Local tumor ablation (LTA) and non-interventional management (NIM) emerged as alternative management options for T1a renal cell carcinoma (RCC). We investigated trends and cancer-specific mortality (CSM) after LTA and NIM, compared to partial nephrectomy (PN). METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2015), T1a RCC patients treated with PN, LTA or NIM were identified. Esti...

We evaluated prognostic risk factors of recurrence-free survival (RFS), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS) outcomes in patients with non-metastatic renal cell carcinoma (nmRCC) after curative nephrectomy during long-term-follow-up. The medical records of 4260 patients with nmRCC who underwent curative nephrectomy between 2000 and 2012 from five Korean institutions and followed-up after postoperative 1-month until December 2017 were retrospectively analyzed for RFS, MFS, OS, and CSS. During the median 43.86 months of follow-up, 342 recurrences, 127 metastases, and 361 d...

The aim of the study was to report the experience and outcomes of Xp11.2 translocation renal cell carcinoma (tRCC) patients with tumor thrombus undergoing radical nephrectomy and thrombectomy. Between January 2017 and December 2017, 66 consecutive patients with RCC and venous thrombus involvement received surgical treatment at Peking University Third Hospital. Of which, 5 patients were confirmed of Xp11.2 tRCC, 61 patients were diagnosed of non-tRCC subtypes including 45 ccRCCs, 10 pRCCs, and 6 other subtypes. Demographic, clinical, operation, pathological and follow-up data were extracted for analysis. Prognostic factors...

Rationale: Conventional computerized tomography (CT) examination can differentiate renal cortical tumor from urothelial carcinoma on the basis of the highly contrast-enhanced vessels in renal cortical tumors. However, the capillary distribution of renal cell carcinoma (RCC) has been under-investigated. Here, we present a micro-CT image of tumor tissue in a patient with RCC. Patient concerns: The patient was a 72-year-old woman with a past history of diabetes mellitus and hypertension. She did not have tumor-related symptoms. Diagnosis and interventions: The tumor was diagnosed using abdominal CT during her yearly r...

Abstract Purpose: The use of VEGFR TKIs for the adjuvant treatment of renal cell carcinoma (RCC) remains controversial. We investigated the effects of adjuvant VEGFR TKIs on circulating cytokines in the ECOG-ACRIN 2805 (ASSURE) trial.Experimental Design: Patients with resected high-risk RCC were randomized to sunitinib, sorafenib, or placebo. Plasma from 413 patients was analyzed from post-nephrectomy baseline, 4 weeks, and 6 weeks after treatment initiation. Mixed effects and Cox proportional hazards models were used to test for changes in circulating cytokines and associations between disease-free survival (DFS)...

ui SC Abstract PURPOSE: To analyze the intratumoral immunohistochemical expression of renin and its value as a prognostic factor for recurrence in nonmetastatic clear cell renal cell carcinoma (ccRCC). METHODS: A total of 498 patients with nonmetastatic ccRCC from the Latin American Renal Cancer Group database who underwent partial or radical nephrectomy between 1990 and 2016 were selected. All cases were revised, and 2 distinct samples were obtained for tissue microarray construction. Ten years of follow-up was assessed, and disease-free survival rates (DFS) were analyzed. Renin expression was classified qua...
