Mechanism of Action and Clinical Efficacy of CDK4/6 Inhibitors in BRCA-Mutated, Estrogen Receptor-Positive Breast Cancers: Case Report and Literature Review.

Sensitivity to endocrine therapy of patients with estrogen receptor (ER)-positive metastatic breast cancer and germline mutations is not yet fully elucidated. Furthermore, the registration trials of CDK 4/6 inhibitors in combination with endocrine therapy lacked of a pre-specified subgroup analysis in mutation carriers. We report clinical history of two patients with BRCA-mutated, ER-positive metastatic breast cancer treated with letrozole plus the CDK 4/6 inhibitor palbociclib.

Triple negative status and BRCA mutations in contralateral breast cancer: a population-based study.

Background And Aim Of The Work: BRCA1/2 mutation carriers diagnosed with breast cancer have a strong life-time risk of developing contralateral breast cancer (CBC). We performed a population-based study with the aim of estimating the proportion of CBC associated with BRCA1/BRCA2 mutations, and the contribution of germline mutations to both molecular and clinical features of these tumors.

Methods: Fifty-five women with invasive CBC consecutively seen at the at the Genetic Oncology Service of the University Hospital of Parma from 2000 to 2011 were subjected to BRCA1/2 testing.

The Kidney Donor Profile Index (KDPI) of marginal donors allocated by standardized pretransplant donor biopsy assessment: distribution and association with graft outcomes.

Pretransplant donor biopsy (PTDB)-based marginal donor allocation systems to single or dual renal transplantation could increase the use of organs with Kidney Donor Profile Index (KDPI) in the highest range (e.g. >80 or >90), whose discard rate approximates 50% in the United States.

Trends in immune cell function assay and donor-specific HLA antibodies in kidney transplantation: A 3-year prospective study.

The immune cell function assay (ICFA) and de novo anti-donor-specific HLA antibodies (DSA) have been proposed as assays for immune monitoring in renal transplantation, but longitudinal studies examining the modification of both parameters over time and their relation with clinical events are lacking. We prospectively measured longitudinal changes in ICFA and DSA levels in 55 kidney transplant recipients over 3-year follow-up (534 visits) and analyzed their relation with the risk of developing acute rejections or infections. Seven patients (12.

HLA and killer immunoglobulin-like receptor genes as outcome predictors of hepatitis C virus-related hepatocellular carcinoma.

Purpose: We evaluated the impact of the killer immunoglobulin-like receptors (KIR) of natural killer (NK) cells and of their HLA ligands over the clinical outcome of hepatitis C virus (HCV)-related hepatocellular carcinoma after curative treatment by either surgical resection or radiofrequency thermal ablation (RTA).

Experimental Design: Sixty-one consecutive patients with HCV-related hepatocellular carcinoma underwent KIR genotyping and HLA typing. A phenotypic/functional characterization of NK cells was carried out in patients with different KIR/KIR-ligand genotype.

Donor-specific anti-HLA antibodies after bone-graft transplantation. Impact on a subsequent renal transplantation: a case report.

Immunological evaluation by panel-reactive antibody (PRA) and determination of anti-HLA specificity are important phases in the evaluation of patients awaiting kidney transplantation. The main causes of immunization are previous solid organ transplantation, hemotransfusion, and pregnancy. It is also possible that immunogenicity can be triggered by vascularized tissue grafts.

[Anti-HLA antibodies after bone graft and their impact on kidney transplant programs].

Immunological evaluation by panel reactive antibody (PRA) and determination of anti-HLA specificity is an important phase in the assessment of patients awaiting kidney transplant. The main causes of immunization are previous solid organ transplants, blood transfusions, and pregnancy; immunogenicity can also be triggered by vascularized tissue grafts. Immune induction by cryopreserved bone allografts is not yet fully understood.

Do physician recommendations for colorectal cancer screening differ by patient age?

Colorectal cancer screening is underutilized, resulting in preventable morbidity and mortality. In the present study, age-related and other disparities associated with physicians' delivery of colorectal cancer screening recommendations were examined. The present cross-sectional study included 43 physicians and 618 of their patients, aged 50 to 80 years, without past or present colorectal cancer.

BRCA mutations, molecular markers, and clinical variables in early-onset breast cancer: a population-based study.

Early age at onset is generally considered an indicator of genetic susceptibility to breast cancer. To address both the proportion of early-onset breast cancer associated with BRCA-1 or BRCA-2 germline mutation and the contribution of germline mutations to the clinical features and outcome of these tumors, we analyzed molecular status and clinical variables of a population-based sample of 66 Italian women diagnosed with breast cancer before the age of 40 who were unselected for family history. BRCA mutations were screened by automated sequencing of the entire BRCA-1 and BRCA-2 coding regions and splice junctions.

Colorectal cancer screening: physicians' knowledge of risk assessment and guidelines, practice, and description of barriers and facilitators.

Background: Physician nonadherence to colorectal cancer (CRC) screening recommendations contributes to underuse of screening.

Objective: To assess physicians' knowledge of CRC screening guidelines for average-risk individuals, perceived barriers to screening and practice behaviours.

Methods: Between October 2004 and March 2005, staff physicians working in three university-affiliated hospitals in Montreal, Quebec, were surveyed.

Combined liver-kidney transplantation with preformed anti-HLA antibodies: a case report.

A pretransplant positive cross-match is a contraindication for kidney transplantation, unlike in liver transplantation (OLT). In combined liver kidney transplantation (LKT) it is hypothesized that liver can protect kidney from rejection. We report the case of a 35-year-old woman on renal replacement therapy with gastrointestinal tract compression due to a hematoma following spontaneous liver rupture (May 2004).

Molecular profile and clinical variables in BRCA1-positive breast cancers. A population-based study.

Purpose: To evaluate the clinical features of breast cancer patients with genetic susceptibility to this disease and to investigate the contribution of BRCA1 germline mutations to the phenotype of these tumors.

Patients And Methods: We reviewed the clinical and pathological records of 102 women with suspected inherited susceptibility to breast cancer consecutively seen at the Genetic Oncology Service of Parma, Italy. Sixty-two patients with a high probability of harboring a germline, cancer-predisposing mutation were tested for BRCA1 mutations.

A breast cancer patient from Italy with germline mutations in both the BRCA1 and BRCA2 genes.

We report the first case in Italy of a non-Ashkenazi double heterozygote for BRCA1 and BRCA2 genes. This finding is predictably rare, with a maximum frequency of 1/250,000. The proband and her mother were diagnosed with early-onset breast cancer.

Outcome of pregnancy after organ transplantation: a retrospective survey in Italy.

The number of women who decide to have a child after organ transplantation has increased. We determined the outcomes of 67 pregnancies of women who had undergone kidney, liver or heart transplantation. All recipients had been maintained on immunosuppressive therapy before and during pregnancy.

Novel association of HLA-haplotypes with primary sclerosing cholangitis (PSC) in a southern European population.

Aims: In patients with with primary sclerosing cholangitis we investigated the major histocompatibility complex (MHC) genes and mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

Methods: In 64 PSC patients and 183 normal controls of the same population (Northern Italy), allelic polymorphisms at the DNA level were investigated in MHC region genes: HLA-DRB1, HLA-DQB1 and HLA-B, tumour necrosis factor A (TNFA), and in CFTR gene, with polymerase chain reaction-based methodologies.

Results: Frequencies of DRB1*01, DQA1*0101, DQB1*0102 (14 vs.

Pregnancy after renal transplantation in Italian patients: focus on fetal outcome.

Background: In the last few years advances in surgical techniques and immunosuppression have improved not only survival, but also quality of life in organ transplanted patients. Hence, the number of women of child-bearing age who decide to have a child--which means resuming a normal life--has increased. This multicenter retrospective study describes pregnancies after kidney transplantation and is the first such survey in Italy.

Identification of anchovy (Engraulis encrasicholus L.) and gilt sardine (Sardinella aurita) by polymerase chain reaction, sequence of their mitochondrial cytochrome b gene, and restriction analysis of polymerase chain reaction products in semipreserves.

A method of authenticating anchovy (Engraulis encrasicholus L.) and gilt sardine (Sardinella aurita) semipreserves (salt-cured and fillets in oil) has been developed by polymerase chain reaction (PCR) followed by sequence and restriction site analysis. The amplification of a fragment of the cytochrome b gene by universal primers produced a 376 base pairs (bp) fragment in all samples analyzed.

X-linked Alport syndrome: an SSCP-based mutation survey over all 51 exons of the COL4A5 gene.

The COL4A5 gene encodes the alpha5 (type IV) collagen chain and is defective in X-linked Alport syndrome (AS). Here, we report the first systematic analysis of all 51 exons of COL4A5 gene in a series of 201 Italian AS patients. We have previously reported nine major rearrangements, as well as 18 small mutations identified in the same patient series by SSCP analysis of several exons.
