PURPOSE Estrogen receptor (ER) expression predicts improved breast cancer-specific survival and reduced risk of recurrence and is targeted in breast cancer therapy. A high-quality antibody to identify ER-positive patients plays an important role in clinical decision making for women with breast cancer. This study evaluates immunohistochemistry using two(More)
Estrogen receptor (ER) expression is routinely assessed by immunohistochemistry (IHC) in breast carcinoma. Our study compares visual scoring of ER in invasive breast cancer by histopathologists to quantitation of staining using a fully automated system. A tissue microarray was constructed from 4,049 cases (3,484 included in analysis) of invasive breast(More)
The existence of non-small cell lung carcinoma with neuroendocrine differentiation as a distinct entity and its relevance for prognostic and treatment purposes is controversial. This study assesses the frequency and biologic and prognostic significance of neuroendocrine (NE) expression of synaptophysin (SNP), chromogranin (Ch), and neural cell adhesion(More)
TAFRO syndrome is a rare constellation of symptoms: thrombocytopenia, anasarca, reticulin fibrosis of the bone marrow, renal dysfunction, and organomegaly. Its pathogenesis involves an excessive and inappropriate cytokine storm, most notably from IL-6, causing multiorgan failure; however, its etiology is undetermined. Starting in 2012, TAFRO syndrome was(More)
Spontaneous remission of chronic lymphocytic leukemia (CLL) is an unusual and poorly characterized event. We performed a search for spontaneous remission in patients with CLL. Cases must have had a pathological diagnosis of CLL with disease duration > 6 months. Spontaneous remission was defined as absence of lymphadenopathy or splenomegaly with lymphocyte(More)
Mevalonate kinase deficiency (MKD) is a rare inborn error of metabolism caused by mutations in the mevalonate kinase (MVK) gene. The clinical phenotype is variable, ranging from the hyperimmunoglobulinemia D and periodic fever syndrome (HIDS) to mevalonic aciduria (MA), a severe metabolic disease. We report here for the first time (to our knowledge) the(More)
Bile aspiration during endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography has been used as a diagnostic tool in the evaluations of pancreatic and biliary tree strictures for the last two decades. However, recently biliary tract brush cytology has become the method of choice in evaluating pancreatic/biliary tract(More)
Our objective was to evaluate the non-germinal center (GC) profile as a marker for response and survival in DLBCL and to compare the characteristics of patients with GC and non-GC DLBCL treated with rituximab-containing regimens. In this patient-level meta-analysis, retrospective data from 712 newly diagnosed DLBCL patients treated with chemoimmunotherapy(More)
The purpose of this study was to assess whether the same principles to evaluate renal transplant by fine-needle aspiration (FNA) for rejection could be applied to pancreatic allograft. Between 1996-1998, 25 ultrasound-guided FNAs on 13 patients with pancreatic allograft were performed and ThinPrep made. The percentage of lymphocytes, lymphoblasts,(More)
Cardiac involvement by sarcoidosis and concomitant deposition of AL amyloid is an uncommon association. We describe the case of a 53-year-old African-American man with a 7-year history of dilated nonischemic cardiomyopathy and severe cardiac failure who underwent orthotopic heart transplantation. His prior cardiac biopsies had only mild myocyte hypertrophy(More)
