Fertility and abortion: A population-based comparison between women with cancer and those in childbearing age.

Objectives: Concurrence of pregnancy and cancer diagnosis is increasingly frequent in Italy. The study aimed to compare women with pregnancy-associated cancers (PACs) to those of childbearing age, focusing on fertility, induced abortion, and miscarriage.

Methods: The population-based study included women aged 15-49 years, both with and without PAC, who were residents in the area covered by the 19 participating Cancer Registries between 2003 and 2015 and identified by individual deterministic linkage with the Hospital Discharge Database.

One-instrument, objective microsatellite instability analysis using high-resolution melt.

In recent years, immune checkpoint inhibitors have proved immense clinical progression in the treatment of certain cancers. The efficacy of immune checkpoint inhibitors is correlated with mismatch repair system deficiency and is exceptionally administered based exclusively on this biological mechanism independent of the cancer type. The promising effect of immune checkpoint inhibitors has left an increasing demand for analytical tools evaluating the mismatch repair status.

Detection of BRAF mutations in malignant melanoma and colorectal cancer by SensiScreen® FFPE BRAF qPCR assay.

Mutations in BRAF exon 15 lead to conformational changes in its activation loops, resulting in constitutively active BRAF proteins which are implicated in the development of several human cancer types. Different BRAF inhibitors have been developed and introduced in clinical practice. Identification of BRAF mutations influences the clinical evaluation, treatment, progression and for that reason a sensitive and specific identification of BRAF mutations is on request from the clinic.

ABCB4 variants in adult patients with cholestatic disease are frequent and underdiagnosed.

Background: Heterozygous ABCB4 variants are not routinely tested in adults with cholestasis because of their supposed rarity and high costs.

Methods: Nineteen adult patients presenting with unexplained cholestasis, and/or recurrent gallstones were included; genotyping was not done in five due to lack of health insurance approval.

Results: heterozygous ABCB4 variants were identified in seven patients, followed by cascade testing of 12 family members: one patient underwent liver transplantation at age 40 for end-stage liver disease; one had compensated cirrhosis; all symptomatic adults had gallstones, including four with low phospholipid-associated cholelithiasis; four had intrahepatic cholestasis of pregnancy; all children and one 54-year old female were asymptomatic.

Primary biliary cholangitis with normal alkaline phosphatase: A neglected clinical entity challenging current guidelines.

Background & Aim: The diagnosis of primary biliary cholangitis (PBC), an uncommon immune-mediated cholestatic liver disease, is based on positive circulating anti-mitochondrial (AMA) and/or PBC-specific anti-nuclear autoantibodies (ANA), coupled with elevated serum alkaline phopsphatase (ALP) levels. Timely initiation of treatment with ursodeoxycholic acid prevents progression to cirrhosis and liver failure. We aimed at investigating liver histology in patients with normal ALP level and positive AMA and/or PBC-specific ANA.

Risk of Malignancy (ROM) of Thyroid FNA Diagnosed as Suspicious for Malignancy or Malignant: an Institutional Experience with Systematic Review and Meta-Analysis of Literature.

A universal recommendation does not exist for thyroid FNA suspicious for malignancy (SFM). In this context, the guidelines have estimated a risk of malignancy (ROM) from 50 to 80% and both total thyroidectomy and lobectomy may be indicated. This study aimed to (1) retrospectively evaluate the SFM (i.

Histologic Outcome of Indeterminate Thyroid Nodules Classified at Low or High Risk.

The revised Italian consensus for the classification and reporting of thyroid cytology (ICCRTC) was published in 2014. Very recently, a high reliability of ICCRTC in classifying low and high risk indeterminate nodules (Tir 3A and Tir 3B, respectively) was demonstrated. This finding prompted us to review our case series of thyroid indeterminate lesions to verify these data.

Deregulation of sialidases in human normal and tumor tissues.

Background: Aberrant sialylation is a characteristic feature associated with cancer. The four types of mammalian sialidases identified to date have been shown to behave in different manners during carcinogenesis. While NEU1, NEU2 and NEU4 have been observed to oppose malignant phenotypes, the membrane-bound sialidase NEU3 was revealed to promote cancer progression.

Pure intraductal carcinoma of the parotid gland: Cytologic findings on FNA sample. Report of one case.

One case of intraductal carcinoma of the parotid gland in a 67-year-old male patient is here introduced. The patient, who had a one-year history of a parotid mass, had undergone ultrasound and MRI examination that disclosed a 13x4x3 mm well delimited nodular mass of the accessory lobe of his left parotid gland. Ultrasound-guided Fine Needle Aspiration (FNA) had been performed by the clinician.

SensiScreen®KRAS exon 2-sensitive simplex and multiplex real-time PCR-based assays for detection of KRAS exon 2 mutations.

Activating mutations in codon 12 and codon 13 of the KRAS (Kirsten rat sarcoma viral oncogene homolog) gene are implicated in the development of several human cancer types and influence their clinical evaluation, treatment and prognosis. Numerous different methods for KRAS genotyping are currently available displaying a wide range of sensitivities, time to answer and requirements for laboratory equipment and user skills. Here we present SensiScreen® KRAS exon 2 simplex and multiplex CE IVD assays, that use a novel real-time PCR-based method for KRAS mutation detection based on PentaBase's proprietary DNA analogue technology and designed to work on standard real-time PCR instruments.

ALK testing in lung adenocarcinoma: technical aspects to improve FISH evaluation in daily practice.

Introduction: Anaplastic lymphoma kinase (ALK) gene rearrangement characterizes a subgroup of patients with lung adenocarcinoma who may benefit from ALK inhibitors. Fluorescence in situ hybridization (FISH) with a break-apart/split-signal strategy is the gold standard to investigate ALK. The cutoff to define ALK positivity has been settled at 15% or greater.
