Brain metastasis in a patient with a sarcomatoid variant RCC with well-controlled extracerebral metastases by temsirolimus.
BACKGROUND The sarcomatoid variant of metastatic renal cell carcinoma (RCC) has often an aggressive course and a poor prognosis, particularly when accompanied with brain metastasis. CASE REPORT We describe the case of a patient with sarcomatoid variant RCC in whom brain metastasis was observed as a new lesion during treatment with temsirolimus, despite other extracerebral metastatic lesions b...
متن کاملSarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component

Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC.

متن کاملRCC - 5 and its
We investigate the computational properties of the spatial algebra RCC-5 which is a restricted version of the RCC framework. The satis-ability problem for RCC-5 is known to be NP-complete but not much is known about its approximately four billion subclasses. We provide a complete classiication of satissability for all these subclasses into polynomial and NP-complete respectively. In the process...
متن کاملOn countable RCC models
Region Connection Calculus (RCC) is the most widely studied formalism of Qualitative Spatial Reasoning. It has been known for some time that each connected regular topological space provides an RCC model. These ‘standard’ models are inevitable uncountable and regions there cannot be represented finitely. This paper, however, draws researchers’ attention to RCC models that can be constructed fro...

primary endpoint, but also the secondary endpoints that should corroborate the primary endpoint, will stand. This approach is based on the Prentice principle, which states that a result has a higher probability of being truly positive if other related endpoints are also positive 1. An advantage in progression-free survival (pfs) has more chance of being true if a statistically significant advan...
