Invasive lobular carcinoma of the breast is known to produce intracellular mucin and has been recognized in single-case reports to show extracellular mucin production, as well. This latter morphology is not only rare but must also be under- or misdiagnosed. The aim was to better characterize this entity. Cases of lobular cancers demonstrating extracellular mucin formation were identified in a multi-institutional effort and their clinical and morphologic features were assessed. Immunohistochemistry was used to characterize the E-cadherin-membrane complex, neuroendocrine differentiation, and to some extent, mucin formation...

Urothelial carcinoma (UC), arising from the urothelium of the urinary tract, can occur in the upper (UTUC) and the urinary bladder (UBUC). A representative molecular aberration for UC characteristics and prognosis remains unclear. Data mining of Gene Expression Omnibus focusing on UBUC, we identified sulfatase-1 (SULF1) upregulation is associated with UC progression. SULF1 controls the sulfation status of heparan sulfate proteoglycans and plays a role in tumor growth and metastasis, while its role is unexplored in UC...

Cystatin SN (CST1) belongs to the type 2 cystatin (CST) superfamily, which restricts the proteolytic activities of cysteine proteases. CST1 has been recently considered to be involved in the development of several human cancers. However, the prognostic significance and function of CST1 in breast cancer remains unknown. In the current study, we found that CST1 was generally upregulated in breast cancer at both mRNA and protein level. Furthermore, overall survival (OS) and disease-free survival (DFS) in the low CST1 expression subgroup were significantly superior to the high CST1 expression subgroup (OS, p < 0...

BACKGROUND: Treatment for early-invasive adenocarcinoma of the cervix remains controversial. Although data have shown similar survival rates to those seen with squamous cell carcinoma, conservative options for patients with microinvasive adenocarcinoma have not been as widely accepted. Despite comparable survival outcomes, patients with early-invasive adenocarcinoma are still routinely subjected to more radical surgical techniques than their equivalently staged squamous cell counterparts...

At present, the risk factors for distant recurrence among patients with early ipsilateral breast tumor recurrence (IBTR) require further investigation. Early IBTR is defined as occurring within 3 years following the initial surgery. In the current study, 40 patients with early IBTR were examined to determine the risk factors for distant recurrence. A node-positive status at the time of primary surgery and the administration of adjuvant chemotherapy following the primary surgery were significantly correlated with poorer distant disease-free survival (P=0...

Analyzing the schizophrenia connectome can identify illness-related alterations in connectivity across the brain. An important question that remains unanswered is whether connectivity alterations are already evident at the onset of illness, before treatment with antipsychotic medication and possible influences of neuroprogressive or secondary alterations related to chronic illness duration. In the present study, diffusion tensor imaging and deterministic fiber tractography were performed with 137 antipsychotic-naive first-episode schizophrenia patients and 113 matched healthy controls...

Aims: Shortening of the atrial-His bundle (AH) interval during the sinus rhythm is occasionally observed after slow pathway ablation for atrioventricular nodal re-entrant tachycardia (AVNRT). In addition, high-rate atrial pacing is useful for avoiding atrioventricular block. We hypothesized that shortening of the AH interval during slow pathway ablation under high-rate atrial pacing would lead to successful ablation of typical AVNRT. Methods and results: This retrospective study included 37 patients in whom successful ablation of typical AVNRT was performed under atrial pacing...

BACKGROUND: Periampullary cancers are uncommon malignancies, often amenable to surgery. Several studies have suggested a role for adjuvant chemotherapy and chemoradiotherapy in improving survival of patients with periampullary cancers, with variable results. The aim of this meta-analysis was to determine the survival benefit of adjuvant therapy for periampullary cancers. METHODS: A systematic review was undertaken of literature published between 1 January 2000 and 31 December 2015 to elicit and analyse the pooled overall survival associated with the use of either adjuvant chemotherapy or chemoradiotherapy versus observation in the treatment of surgically resected periampullary cancer...
