[Clinicopathological characterization and autopsybased classification of the Cancer of Unknown Primary origin (CUP) syndrome].

Cancer of Unknown Primary origin (CUP) is characterized by metastatic tumor spread without identifiable primary tumor. CUP cohort was selected from 6966 autopsy cases (2001-2014). Type-1 ("clinical") CUPs: primary site was not found clinically but identified by autopsy.

PREDICTIVE VALUE OF SOMATIC MUTATIONS FOR THE DEVELOPMENT OF MALIGNANCY IN THYROID NODULES BY CYTOPATHOLOGY.

Objective: The purpose of our prospective longitudinal study was to evaluate the predictive efficacy of genetic testing for malignancies in fine-needle aspiration biopsy samples that are cytologically benign at the time of biopsy.

Methods: A total of 779 aspirated cytological samples collected from thyroid nodules of 626 patients were included in a 3-year follow-up study. Consecutive patients with cytologically benign thyroid nodules by the Bethesda System for Reporting Thyroid Cytopathology were enrolled in the study.

Reliability of immunocytochemistry and fluorescence in situ hybridization on fine-needle aspiration cytology samples of breast cancers: A comparative study.

Introduction: To characterize breast tumors and metastases, fine-needle aspiration cytology (FNAB) can be a favorable first choice. However, the diagnostic accuracy of ancillary tests applied to FNAB samples is yet to be validated.

Patients And Methods: We examined 110 breast cancer patients' paired cytological and surgical resection specimens evaluated between 2005 and 2014.

[The role of aspiration cytology in tumor diagnostics].

Fine needle aspiration biopsy (FNAB) of focal lesions is a quick, relatively simple and cost-effective diagnostic method. However, performing aspirations and interpreting smears require skill and experience. Before initiating an aspiration the doctor needs to be aware of the limits of cytology as it is vital to know what kind of diagnostic issues can be answered upon a smear and what kind of questions cannot.

Total aortic arch replacement: superior ventriculo-arterial coupling with decellularized allografts compared with conventional prostheses.

Background: To date, no experimental or clinical study provides detailed analysis of vascular impedance changes after total aortic arch replacement. This study investigated ventriculoarterial coupling and vascular impedance after replacement of the aortic arch with conventional prostheses vs. decellularized allografts.
