INTRODUCTION Sunitinib, an oral multitargeted tyrosine kinase inhibitor, is widely used in the treatment of renal cell carcinoma and gastrointestinal stromal tumor and has had a variety of adverse events. However, sunitinib-related acute cholecystitis has been reported in only two patients with gastrointestinal stromal tumor and renal cell carcinoma (clear cell subtype). CASE PRESENTATION A 7...
Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder associated with a germline mutation of the folliculin gene (FLCN). The affected families have a high risk for developing multiple renal cell carcinomas (RCC). Diagnostic markers that distinguish between FLCN-related RCC and sporadic RCC have not been investigated, and many patients with undiagnosed BHD fail to receive proper medical care. W...
BACKGROUND Renal cancers account for more than 3% of all adult malignancies and cause more than 23,400 deaths per year in China alone. The four most common types of kidney tumours include clear cell, papillary, chromophobe and benign oncocytoma. These histological subtypes vary in their clinical course and prognosis, and different clinical strategies have been developed for their management. So...
Light microscopy has revealed that the anterior lobe of the pituitary gland contains many kinds of glandular cells, which have been classified according to the staining behavior of each cell type after the use of various methods of differential staining. At the early stage in the development of pituitary morphology, the cell types were designated as acidophil, basophil or chromophobe suggesting...
OBJECTIVE To investigate microcirculatory differences between pathologic types of kidney tumor using 320-slice dynamic volume CT perfusion. METHODS Perfusion imaging with 320-slice dynamic volume CT was prospectively performed in 85 patients with pathologically proven clear cell renal cell carcinoma (RCC) (n = 66), papillary RCC (n = 7), chromophobe RCC (n = 5), angiomyolipoma (AML) with mini...
New fluorescent Fluolid dyes have advantages over others such as stability against heat, dryness, and excess light. Here, we performed simultaneous immunostaining of renal tumors, clear cell renal cell carcinoma (RCC), papillary RCC, chromophobe RCC, acquired cystic disease-associated RCC (ACD-RCC), and renal angiomyolipoma (AML), with primary antibodies against Kank1, cytokeratin 7 (CK7), and ...
PURPOSE Sorafenib represents one of the two standards of care for patients with metastatic renal cell carcinoma (mRCC). In the present review, we provide information regarding the use of sorafenib in first and second lines. We also describe results for dose escalation strategies. Finally, we provide data addressing the efficacy of sorafenib in patients with mRCC of non-clear-cell histology. R...
Subtypes of renal tumors have different genetic backgrounds, prognoses, and responses to surgical and medical treatment, and their differential diagnosis is a frequent challenge for pathologists. New biomarkers can help improve the diagnosis and hence the management of renal cancer patients. We extracted RNA from 71 formalin-fixed paraffin-embedded (FFPE) renal tumor samples and measured expres...
Renal cell carcinoma (RCC) comprises 2-3% of all malignancies. Approximately 90% of renal tumors are RCCs, and 15% of these are non-clear cell tumors, which include papillary, chromophobe, Bellini duct (collecting duct) and sarcomatoid tumors. Antiangiogenic agents (sorafenib, sunitinib, pazopanib, temsirolimus, or bevacizumab), have not been specifically evaluated in phase III trials in patien...
