Identificación de las características de los ganglios evaluados en el procedimiento EBUS y su relación con el diagnóstico de malignidad en instituto de alta complejidad en cáncer

Introducción: La EBUS ha sido el foco de numerosos estudios destinados a evaluar su utilidad y rendimiento diagnóstico en diversas patologías. Objetivo principal: Identificación de las características ganglionares evaluadas en el procedimiento de Ultrasonido Endobronquial (EBUS) y su relación con ...

Computed-tomography based scoring system predicts outcome for clinical lymph node-positive patients undergoing radical cystectomy

Int. braz. j. urol; 48 (1), 2022
ABSTRACT Purpose: Contrast-enhanced CT scan is the standard staging modality for patients with bladder cancer undergoing radical cystectomy (RC). Involvement of lymph nodes (LN) determines prognosis of patients with bladder cancer. The detection of LN metastasis by CT scan is still insufficient. Therefo...

MRI-based differentiation between lymphoma and sarcoidosis in mediastinal lymph nodes

J. bras. pneumol; 47 (2), 2021
ABSTRACT Objective: Evaluation of enlarged mediastinal lymph nodes is crucial for patient management. Malignant lymphoma and sarcoidosis are often difficult to differentiate. Our objective was to determine the diagnostic accuracy of MRI for differentiating between sarcoidosis and malignant lymphoma. Me...

Sentinel lymph node biopsy using single-agent mapping tracer (blue dye) after neoadjuvant chemotherapy in a Brazilian cohort of breast cancer patients. Real world evidence

Acta cir. bras; 36 (6), 2021
ABSTRACT Purpose To reduce false-negative rates (FNR) in sentinel lymph node biopsy (SLNB) of clinically positive (cN+) axilla in patients undergoing neoadjuvant chemotherapy (NAC). The removal of three or more lymph nodes with dual-tracer mapping including a radioisotope was used. However, in the Brazi...

Association of sonographic features and clinicopathologic factors of papillary thyroid microcarcinoma for prevalence of lymph node metastasis: a retrospective analysis

ABSTRACT Objective: The objective of the study was to develop an association between clinicopathologic and sonographic features of patients with papillary thyroid microcarcinoma and the prevalence of lymph node metastasis. Subjects and methods: Clinicopathologic and sonographic features of 415 patients...

The effect of regions-of-interest and elasticity modulus selection on differentiating benign and malignant cervical lymph nodes with shear wave elastography

Clinics; 75 (), 2020
OBJECTIVE: Imaging diagnosis of cervical lymphadenopathy has conventionally used ultrasonography. Shear wave elastography (SWE) is a recent ultrasound technological advancement that has shown promise in the important medical problem of differentiating between benign and malignant cervical lymph nodes bas...

The role of endobronchial ultrasound-guided transbronchial needle aspiration in isolated intrathoracic lymphadenopathy in non-neoplastic patients: a common dilemma in clinical practice

J. bras. pneumol; 46 (2), 2020
ABSTRACT Objective: To determine the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in non-neoplastic patients with isolated intrathoracic lymphadenopathy (IL). Methods: This was a retrospective study of patients with isolated IL referred for EBUS-TBNA....

EBUS-TBNA versus surgical mediastinoscopy for mediastinal lymph node staging in potentially operable non-small cell lung cancer: a systematic review and meta-analysis

J. bras. pneumol; 46 (6), 2020
ABSTRACT Objective: Lung cancer (LC) is one of the leading causes of death worldwide. Accurate mediastinal staging is mandatory in order to assess prognosis and to select patients for surgical treatment. EBUS-TBNA is a minimally invasive procedure that allows sampling of mediastinal lymph nodes (LNs). S...

Estudio imagenológico de linfonodos en oncología de cabeza y cuello

RESUMEN En la práctica clínica es habitual el estudio de linfonodos cervicales. La anamnesis y el examen físico orientan la etiología, pero ocasionalmente debemos recurrir a estudios imagenológicos. Esto es muy relevante en contexto de un linfonodo metastásico por un carcinoma escamoso de cabeza y ...

Level V Clearance in Neck Dissection for Papillary Thyroid Carcinoma: A Need for Homogeneous Studies

Abstract Introduction Papillary thyroid carcinoma has a very high rate of lateral neck node metastases, and there is almost unanimity concerning the fact that some sort of formal neck dissection must be performed to address the clinical neck disease in these cases. Although there is an agreement that le...
