“Background: Renal cell carcinoma (RCC) can be considered as two distinct entities:

localized and metastatic Duvelisib disease.

Methods: We conducted a review of the scientific literature published within the past decade pertaining to cytoreductive nephrectomy for metastatic RCC.

Results: Retrospective data and historical prospective series have demonstrated the survival benefit of debulking nephrectomy in well-selected RCC patients. New medical therapies, including vascular endothelial growth factor and mTOR pathway blocking drugs, are active biological agents, with survival improvement and potential regression of metastatic and primary tumors. Our current therapeutic challenge is the optimal integration of multimodal therapy consisting of systemic therapy and

surgery including cytoreductive nephrectomy, debulking, and metastasectomy. Empiric data to guide this decision are limited.

Conclusions: The decision concerning whether medical or surgical therapy should be the primary treatment approach selected must be made on an individual basis, taking into account patient performance status, clinical parameters, and physician expertise and recommendations, thus making each case a unique therapeutic challenge.”
“Background: Clinical experience and literature data suggest that the ability

of pathologists to identify granulomas Selleck BKM120 in cytological specimens from intrathoracic lymphadenopathy varies considerably and may negatively influence the yield of transbronchial needle aspiration (TBNA), both conventional and ultrasound-guided (EBUS-TBNA). Objectives: To describe HM781-36B Protein Tyrosine Kinase inhibitor the cytomorphology of sarcoidal granulomas on TBNA cytology specimens and to analyze the presence of associations between the cytological characteristics of granulomas and the radiographic stage of sarcoidosis. Methods: TBNA cytological specimens from 123 sarcoidosis patients and 14 tuberculosis patients (control population) were reviewed independently by two pathologists blinded to the clinical-radiological details. Results: Sarcoidal granulomas were small [median (IQR) largest diameter: 0.478 (0.318-0.701) mm] and well-formed, round or elliptical in shape, and almost invariably had a regular contour. Background elements lacked necrotic debris or exudate. The density [median (IQR) number of granulomas per slide: 6.85 (3.66-11) vs. 5.25 (2.5-8), p = 0.073] and size [median (IQR) largest diameter: 0.51 (0.319-0.733) vs. 0.398 (0.318-0.522), p = 0.071] tended to be larger in stage I than in stage II sarcoidosis. A necrotic background was common in the tuberculosis cohort studied (79 vs. 0%, p < 0.0001). Conclusions: Granulomas can be reliably identified on TBNA cytological material once their characteristic cytomorphology is delineated.
