Combination of DNA methylation biomarkers with multiparametric magnetic resonance and ultrasound imaging fusion biopsy to detect the local spread of prostate cancer.

Background: This study aimed to investigate the extent of field cancerization adjacent to index lesions in prostate cancer (PCa) by measuring DNA methylation of selected tumor suppressor genes in the perifocal tissue of PCa not visible on multiparametric magnetic resonanse imaging (mpMRI) for the safe zone of focal therapy identification.

Methods: A total of 272 patients were enrolled in this study, 44 patients' tissue biosamples were included in the field cancerization research, and 272 urine samples were included in the urine-based test development. Targeted biopsies were performed using the mpMRI/ultrasoundimage fusion system.

Efficacy of focal high-dose-rate brachytherapy in the treatment of patients diagnosed with low or favourable: intermediate-risk prostate cancer-a protocol for a randomised controlled trial.

Introduction: Prostate cancer (PCa) is men's second most predominant cancer worldwide. Because the prostate-specific antigen test is used in diagnostics, PCa is more often diagnosed in the early stages, making radical treatment of the disease possible. However, it is estimated that over a million men worldwide suffer from radical treatment-related complications.

Urine Molecular Biomarkers for Detection and Follow-Up of Small Renal Masses.

Active surveillance (AS) is the best strategy for small renal masses (SRMs) management; however, reliable methods for early detection and disease aggressiveness prediction are urgently needed. The aim of the present study was to validate DNA methylation biomarkers for non-invasive SRM detection and prognosis. The levels of methylated genes , , , , and were evaluated in 165 serial urine samples prospectively collected from 39 patients diagnosed with SRM, specifically renal cell carcinoma (RCC), before and during the AS via quantitative methylation-specific polymerase chain reaction.

Cutaneous Melanoma with Tonsillar Metastasis: Treatment with Cryoablation.

Metastasis of cutaneous melanoma to the oral cavity is a rare condition. Male patient with cutaneous melanoma metastasis to right tonsil 2 years after radical skin lesion resection was treated with surgery: tonsillectomy and later resection of soft palate were performed. Two years later the patient was diagnosed with progressive disease to right tonsil and soft palate.

Von Hippel-Lindau syndrome and renal tumours: radiological diagnostic and treatment options. A case report and literature review.

Background: Von Hippel-Lindau disease (VHL) is a rare autosomal dominant syndrome diagnosed for 1 out of 36000-45000 newborns and 90% of the patients have a clinical manifestation before 65 years of age. Affected individuals have an increased risk of developing tumours in several organs or their systems. The most common tumours are retinal or central nervous system hemangioblastomas (60-80%) and VHL-associated renal lesions.

Small Intestinal Inflammatory Myofibroblastic Metastasis in the Left Ventricle.

Inflammatory myofibroblastic tumors (IMTs) are rare and usually appear in childhood and adolescence. These tumors often take a benign course, but tend to reoccur in a quarter of cases and metastasize locally. Distant IMT metastases are extremely uncommon.

Extralobar pulmonary sequestration.

Prevalence of pulmonary sequestration accounts for up to 6.4% of all congenital pulmonary malformations. We report on a 40-year-old woman who underwent excision of an aberrant solid retroperitoneal mass in the left subdiaphragmatic area.

Cystic lymph node metastasis in papillary thyroid carcinoma.

Background: Thyroid cancer, especially papillary carcinoma, metastasizes most often into cervical lymph nodes. Cervical ultrasound and ultrasound-guided fine-needle aspiration biopsy are the most sensitive modalities in detecting locoregional neck recurrence.

Objective: The aim of this study was to illustrate the ultrasound spectrum of lymph node metastases from papillary thyroid carcinoma.

[The frequency of malignant disease in cytological group of suspected cancer (ultrasound-guided fine-needle aspiration biopsy of nonpalpable thyroid nodules)].

Background: Fine-needle aspiration biopsy is the most important procedure for differentiating benign thyroid nodules from malignant ones. Traditionally, findings of fine-needle aspiration biopsy are divided into four categories: nondiagnostic, benign lesions, suspected cancer, and malignant lesions. Group suspicious for cancer largely involves follicular neoplasms as well as lesions with cytological features of malignancy.
