The lower levels of NSE in patients who received methylprednisolone may suggest that corticosteroids might be useful in decreasing possible neuronal damage during heart surgery. However, we were not able to demonstrate an adverse neurological outcome.
Giant multilocular prostatic cystadenoma is a rare benign tumor that evolves from the prostate gland. Obstructive voiding symptoms occur in all reported cases. These lesions do not invade adjacent structures. Preoperative radiologic evaluation can define the benign nature of the lesion. Here we report a case of large cystic lesions identified by magnetic resonance imaging and sonographic findings that caused an extensive mass effect in the pelvis. When retrovesical, huge cystic lesions fill the pelvis completely in young men, with high levels of serum prostate-specific antigen, giant multilocular prostatic cystadenoma should be considered as a differential diagnosis. To our knowledge, this is the youngest case of prostatic cystadenoma reported in the literature.
Aldehyde dehydrogenase 1 (ALDH1) has been identified as a marker of cancer stem cells in breast cancer (BC). Recent studies showed that ALDH1 expression is correlated with poor prognostic parameters and worse clinical outcome in BC. We evaluated ALDH1 expression by immunohistochemistry in a series of 217 invasive BCs and investigated the correlation between ALDH1 expression and clinicopathological parameters, molecular subtypes (luminal A, luminal B, human epidermal growth factor receptor 2 [HER2] type, and triple-negative BC [TNBC]), and patient survival. There was a significant association between ALDH1 expression and tumor grade (p < 0.001), i.e., the expression of ALDH1 was higher in high-grade tumors. ALDH1 expression was significantly associated with estrogen and progesterone receptor (ER and PR) negativity (p < 0.001) and HER2 positivity (p = 0.001). ALDH1 expression ratios were higher in HER2 type and TNBC. There was a statistically significant correlation between ALDH1 negativity and luminal A subtype (p < 0.001). The overall and disease free survival were shorter in ALDH1+ tumors, although without statistical significance. We confirm that ALDH1 is a potentially important, poor prognostic factor in BC, associated with high histological grade, ER/PR negativity and HER2 positivity. For more accurate results, ALDH1 expression should be evaluated in larger case series including various types/subtypes of BC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
