BRAFV600E Mutation and p27kip1 Expression in Papillary Carcinomas of the Thyroid ≤1 cm and Their Paired Lymph Node Metastases
2007
BACKGROUND. BRAFV600E mutation and p27kip1 expression have been introduced as novel indicators that may predict prognosis in different tumors, as well as in papillary thyroid carcinomas. METHODS. Tissue samples from 214 consecutive patients who underwent total or near-total thyroidectomy with histological diagnosis of papillary thyroid carcinoma (PTC) ≤1 cm were analyzed for BRAFV600E mutation by a real-time, allele-specific amplification and for p27kip1 expression by immunohistochemistry. RESULTS. The BRAFV600E mutation was detected in 88 of the tumors examined, with significant differences between groups with and without lymph node (LN) metastases; the mean age of patients with BRAFV600E …
Psychiatric and neurological symptoms in patients with Niemann-Pick disease type C (NP-C): Findings from the International NPC Registry
2017
Objectives: Niemann-Pick disease type C (NP-C) is a rare inherited neurovisceral disease that should be recognised by psychiatrists as a possible underlying cause of psychiatric abnormalities. This...
The Influence of the Primary Tumor on the Long-term Results of Pulmonary Metastasectomy for Metastatic Renal Cell Carcinoma
2011
OBJECTIVE To investigate one of the primary tumor (PT) on pulmonary metastasectomy (PM) for metastatic renal cell carcinoma (RCC) and to define prognostic factors. METHODS Retrospective review of patients with pulmonary metastases from RCC from January 1999 through December 2008 was performed. All patients underwent PM with curative intend. TNM-classification, tumor stage and PT grade, disease-free-interval (DFI) from nephrectomy to the diagnosis of metastasis, systemic chemotherapy before surgical intervention, surgical procedures, morbidity, mortality, and survival were investigated. RESULTS One-hundred seven consecutive patients (age 61.5 ± 9.6 years) underwent PM. Morbidity and mortalit…
Metastasectomy With Standardized Lymph Node Dissection for Metastatic Renal Cell Carcinoma: An 11-Year Single-Center Experience
2013
Background Pulmonary metastasectomy (PM) for metastatic renal cell carcinoma is an established method of treatment for selected patients. The incidence of intrathoracic lymph node metastases (ITLNM) and outcomes remain controversial. The purpose of this study was to determine the incidence of ITLNM and long-term outcome of PM for metastatic kidney cancer. Methods From January 1999 to December 2009, 116 patients (82 men, age 61.7 ± 9.0 years) with metastases from kidney cancer underwent PM and systematic lymph node dissection with curative intent. Kaplan-Meier analyses, log-rank test, and Cox regression analyses were used to estimate survival and to determine prognosticators of survival. Res…
pT2 Adenocarcinoma of the Esophagus: Early or Advanced Cancer?
2013
Background There is an increasing trend to include patients with esophageal carcinoma invading the muscularis propria (pT2) in neoadjuvant therapy regimens. But it is unclear which patients have prognostic benefit from this strategy. The aim of this study was to assess the prognosis and prognostic factors in patients with pT2 esophageal adenocarcinoma to further optimize treatment strategies. Methods Included were patients with pT2 esophageal adenocarcinoma treated operatively at three centers specializing in upper gastrointestinal surgery. There were 159 patients (139 male) without induction therapy; median age was 64.5 years. Survival was analyzed by univariate and multivariate analysis. …
Haematopoietic stem cell transplantation for vasculitis including Behçet's disease and polychondritis: a retrospective analysis of patients recorded …
2006
Objective: To evaluate the feasibility of haematopoietic stem cell transplantation (HSCT) in vasculitis. Methods: This is a retrospective analysis of patients who had received HSCT for vasculitic diseases and have been reported to the European League Against Rheumatism autoimmune disease or European Bone Marrow Transplantation ProMISe databases. Information about the disease and outcome was obtained by a questionnaire sent to the referring centres. Response of the disease to HSCT was defined as partial or complete responses according to the ability to reduce immunosuppression after HSCT. In addition, the Medline database was searched for reports on HSCT in patients with vasculitis. Results:…
Lymph Node Metastases in Non-Muscle Invasive Bladder Cancer are Correlated With the Number of Transurethral Resections and Tumour Upstaging at Radica…
2005
The first paper in this section, from Mainz, attempts to identify the clinical variables associated with the prevalence of lymph node metastases in non-muscle invasive bladder cancer. The authors found that delay in cystectomy in this potentially dangerous type of tumour is to be avoided, with a higher incidence of lymph node metastases as the number of transurethral resections increases. A paper from Austria shows that in renal carcinoma the pT1 subdivision is associated with differences in conventional histopathology and expression of biomarkers. OBJECTIVE To identify clinical variables associated with the prevalence of lymph node metastases (LNMs) in patients with non-muscle invasive tra…
Occupational exposure to immunologically active agents and risk for lymphoma: The European Epilymph case-control study
2013
Objectives: Allergies and asthma may be protective for the development of lymphoma. We evaluated whether occupational allergens that provoke immune reactivity and asthma through an IgE-mediated pathway are protective for lymphoma. Methods: The Epilymph study includes histologically or cytologically confirmed Hodgkin, B-cell, and T-cell lymphoma cases from six European countries (Spain, France, Germany, Italy, Ireland, and Czech Republic) recruited in 1998-2004. Controls were frequency matched to cases by age, gender, and study centre. Lifetime occupational exposure to seven high molecular weight (HMW) agents was evaluated through an asthma-specific job-exposure matrix. 2205 lymphoma cases a…
Criteria for defining a complete remission in acute myeloid leukaemia revisited. An analysis of patients treated in HOVON-SAKK co-operative group stu…
2005
Complete remission (CR) in patients with acute myeloid leukaemia (AML) is the primary endpoint for the evaluation of induction treatment and treatment strategies. However, the choice and application of the criteria for a haematological CR can often become a subject of debate because of regeneration more than 5% blasts may be present at the time of response evaluation; platelet and neutrophil recovery may be incomplete and marrow cellularity can vary. This study examined the individual parameters for CR in 1250 adult patients with de novo AML treated according to three successive study protocols. Patients with < or =5% blasts showed the best overall survival (OS) and the lowest relapse risk …
Can side-specific biopsy findings predict the side of nodal metastasis in clinically localized prostate cancer? Results from a multicenter prospectiv…
2013
Background To evaluate the correlation between the side of positive biopsy (Bx) and the risk of lymph-node metastases (LNMs) on each side and to quantify the risk of contralateral LNMs in patients with unilateral positive biopsy. Methods We analyzed the outcomes of 1599 patients with complete data regarding the sides of positive Bx and LN (lymph-node). By dividing each prostate into two separate sides, we assessed the accuracy of the side-specific Bx details in determining the side of positive nodes; the area under the receiver-operating characteristic (ROC) (AUCs) was used. For patients with unilateral positive Bx, we assessed the risk of homolateral and contralateral LNMs according to the…
