Multicenter Phase II Study of Lurbinectedin in BRCA-Mutated and Unselected Metastatic Advanced Breast Cancer and Biomarker Assessment Substudy

2018

Purpose This multicenter phase II trial evaluated lurbinectedin (PM01183), a selective inhibitor of active transcription of protein-coding genes, in patients with metastatic breast cancer. A unicenter translational substudy assessed potential mechanisms of lurbinectedin resistance. Patients and Methods Two arms were evaluated according to germline BRCA1/2 status: BRCA1/2 mutated (arm A; n = 54) and unselected ( BRCA1/2 wild-type or unknown status; arm B; n = 35). Lurbinectedin starting dose was a 7-mg flat dose and later, 3.5 mg/m2 in arm A. The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST). The translational substudy of resist…

Application of 1H NMR-based serum metabolomic studies for monitoring female patients with rheumatoid arthritis

2015

AbstractRheumatoid arthritis is a chronic autoimmune-based inflammatory disease that leads to progressive joint degeneration, disability, and an increased risk of cardiovascular complications, which is the main cause of mortality in this population of patients. Although several biomarkers are routinely used in the management of rheumatoid arthritis, there is a high demand for novel biomarkers to further improve the early diagnosis of rheumatoid arthritis, stratification of patients, and the prediction of a better response to a specific therapy.In this study, the metabolomics approach was used to provide relevant biomarkers to improve diagnostic accuracy, define prognosis and predict and mon…

FOCAL ACTIVE COLITIS AS A PREDICTOR OF INFLAMMATORY BOWEL DISEASE: RESULTS FROM A SINGLE-CENTER EXPERIENCE.

2017

The term focal active colitis (FAC) is conventionally used to describe the presence of isolated cryptitis, characterized by an inflammatory infiltrate consisting of intraepithelial neutrophils and/or neutrophils invading the lumen of the criptae, with no other microscopic alteration of the colonic mucosa and, in particular, without the presence of signs of chronic inflammation. To date, only four studies, including one conducted in a pediatric population, have been performed to evaluate the clinical significance of this disease. The aim of this retrospective study on prospectively-collected data is to evaluate the clinical implications of the focal active colitis, since there still remains …

Corrigendum: Natural History of Non-Small-Cell Lung Cancer with Bone Metastases.

2016

We conducted a large, multicenter, retrospective survey aimed to explore the impact of tumor bone involvement in Non-Small Cell Lung Cancer.Data on clinical-pathology, skeletal outcomes and bone-directed therapies for 661 deceased patients with evidence of bone metastasis were collected and statistically analyzed. Bone metastases were evident at diagnosis in 57.5% of patients. In the remaining cases median time to bone metastases appearance was 9 months. Biphosphonates were administered in 59.6% of patients. Skeletal-related events were experienced by 57.7% of patients; the most common was the need for radiotherapy. Median time to first skeletal-related event was 6 months. Median survival a…

Cathepsin D, B and L circulating levels as prognostic markers of malignant progression

1996

Growing evidence indicates that lysosomal Cathepsins D (CD), B (CB) and L (CL) may promote carcinogenesis and tumor progression. Therefore, we evaluated their potential value as biochemical parameters of malignant progression in patients with benign diseases which may undergo malignant transformation, such as liver cirrhosis (LC) and chronic pancreatitis (CHP) as well as in hepatocellular carcinoma (HCC) and pancreatic cancer (DPC). CD, CB and CL serum levels were determined by immunoenzymatic assays in LC, CHP, HCC or DPC patients and correlated with a number of biochemical and clinical parameters of these diseases. CD serum levels were increased in LC, CHP and HCC, but not in the DPC grou…

Periodontal morphological microcirculation in Oral Lichen Planus

2008

This study aimed at evaluating possible differences in the vascular pattern (of periodontal mucosa microcirculation) between healthy patients and patients suffering from PLP (periodontal lichen planus). Fifty-four patients (27 patients suffering from PLP and 27 healthy patients) were examined by means of videocapillaroscopy. The following area was examined for each patient: periodontal mucosa corresponding to 1.1 and 2.1. The following parameters were analyzed on every capillaroscopic image: capillary loop length, loop diameter, capillary tortuosity, capillary density, avascular areas, possible microhaemorrhages, distinctive morphology. The results obtained using videocapillaroscopic softwa…

Aging, longevity, inflammation, and cancer.

2005

Cancer rates increase sharply with age in both sexes, and the majority of cases of cancer occur in patients over the age of 65 years. However, the incidence and mortality for cancer level off around 85-90 years of age, followed by a plateau, or even a decline in the last decades of life. Therefore, it seems reasonable to conclude that centenarians are endowed with a peculiar resistance to cancer. Tumor progression is a complex process that depends on interactions between tumor and host cells. One aspect of the host response, the inflammatory response, is of particular interest because it includes the release of proinflammatory cytokines, some of which may promote tumor growth and hence infl…

Mutational analysis of 105 mucopolysaccharidosis type VI patients

2007

Mucopolysaccharidosis type VI (MPS VI; Maroteaux-Lamy syndrome) is a lysosomal storage disorder caused by mutations in the N-acetylgalactosamine-4-sulfatase (arylsulfatase B, ARSB) gene. ARSB is a lysosomal enzyme involved in the degradation of the glycosaminoglycans (GAG) dermatan and chondroitin sulfate. ARSB mutations reduce enzyme function and GAG degradation, causing lysosomal storage and urinary excretion of these partially degraded substrates. Disease onset and rate of progression is variable, producing a spectrum of clinical presentation. In this study, 105 MPS VI patients—representing about 10% of the world MPS VI population—were studied for molecular genetic and biochemical parame…

Long-Term Impact of Systolic Blood Pressure and Glycemia on the Development of Microalbuminuria in Essential Hypertension

2005

The objective was to assess the temporal impact of factors related to the development of microalbuminuria during the follow-up of young adult normoalbuminurics with high-normal blood pressure or at stage 1 of essential hypertension. Prospective follow-up was conducted on 245 normoalbuminuric hypertensive subjects (mean age 40.9 years; 134 men; blood pressure 139.7/88.6 mm Hg; body mass index 28.5 kg/m 2 ) never treated previously with antihypertensive drugs, with yearly urinary albumin excretion measurements, until the development of microalbuminuria. After enrollment, patients were placed on usual care including nonpharmacological treatment or with an antihypertensive drug regime to achie…
