11 de mar. de 2024 · The 5-year survival rate for patients with clear cell renal cell carcinoma is 50-70%, but it decreases to 10% when metastatic 9. See also WHO classification of tumors of the kidney
Hace 1 día · Background This study was designed to develop an innovative classification and guidance system for renal hilar tumors and to assess the safety and effectiveness of robot-assisted partial nephrectomy (RAPN) for managing such tumors. Methods A total of 179 patients undergoing RAPN for renal hilar tumors were retrospectively reviewed. A novel classification system with surgical techniques was ...
Hace 4 días · e16520 Background: Venous tumor thrombus (VTT) is observed in 4−10% of newly diagnosed RCC patients, and a successful radical nephrectomy and thrombectomy provides considerable palliation to a proportion of nonmetastatic RCC patients with VTT. However, the reported postsurgical survival varies significantly with the 5‐year overall survival (OS) rate ranging from 37.0 to 71.0%. Hence ...
Hace 3 días · In the 57 patients with positive surgical margins, 24 tumors were characterized as having low malignant potential (benign tumors, papillary RCC type I, chromophobe RCC) whereas 33 tumors were classified as having high malignant potential (clear-cell RCC, papillary type II RCC, collecting-duct RCC, and tumors with sarcomatoid differentiation).
Hace 3 días · Sarcomatoid renal cell carcinomas (sRCC) may develop when one of the more common histologic subtypes of renal cell carcinoma degenerates into a sarcoma. On imaging, they are generally large masses, with irregular contours, and malignant-appearing, but do not have specific imaging features. Epidemiology.
Hace 4 días · The Bosniak classification of renal cysts is of limited value in ADPKD. Subtraction CT, MRI or DECT are sensitive to enhancement. MRI. High-resolution T2-weighted MRI is the most sensitive modality for the detection of small renal cysts. Simple cysts are thin-walled and the contents appear similar to water. T1: low signal. T2: high ...

[] research found that Among 821 cT1/2 RCC patients, 245 (29.8%) had adverse pathology.
