1. Correlation between PET-CT and ct in the staging after the treatment of head and neck squamous cell carcinoma
Abstract Objective: The aim of this study is to find out if a single imaging test is enough to follow-up on an oncological post-treatment patient. In such a case, we would know which was more valuable after comparing the two, by CT or PET-CT. Methods: Between January 2012 and July 2018, we collected data from all patients with previous medical history who

2. Analysis of the related risk factors of inguinal lymph node metastasis in patients with penile cancer: A cross-sectional study
ABSTRACT Purpose: To determine independent predictors of inguinal lymph node (ILN) metastasis in patients with penile cancer. Patients and methods: We retrospectively analyzed all patients with penile cancer who underwent surgery at our medical center in the last ten years (n=157). Using univariate and multivariate logistic-regression models, we assessed a

3. Radioactive iodine therapy: multiple faces of the same polyhedron
ABSTRACT The incidence of differentiated thyroid carcinoma (DTC) has increased in recent decades with early stage, low risk papillary thyroid cancer (PTC) being detected and diagnosed. As a result, the psychological, financial, and clinical ramifications of overdiagnosis and excessively aggressive therapy are being increasingly recognized with many authoriti

4. Robotic-assisted nephrectomy with level II IVC thrombectomy using Rummel Tourniquets
ABSTRACT Background: Inferior vena cava (IVC) invasion from renal cell carcinoma (RCC) occurs at a rate of 4-10% (1). IVC thrombectomy (IVC-TE) can be an open procedure because of the need for handling of the IVC (2). The first reported series of robotic management of IVC-TE started in 2011 for the management of Level I - II thrombi with subsequent case rep

5. Wnt3a but not CDX-2 expression is associated with differentiated thyroid cancer
SUMMARY OBJECTIVE: Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression

10. The Role of Imaging in the Preoperative Assessment of Patients with Nasal Obstruction and Septal Deviation-A Retrospective Cohort Study
Abstract Introduction Isolated nasal obstruction (INO) is a common complaint of multiple etiology. The preoperative evaluation of patients presenting with nasal obstruction and deviated nasal septum (DNS) does not typically include imaging. The benefits of performing computed tomography (CT) in the preoperative setting are inconclusive. Objective Assessing
