Tomografía por emisión de positrones asociada con tomografía computarizada en la estadificación de los linfomas
Positron emission tomography combined with computed tomography for the staging of lymphomas

Introducción: Los estudios de imágenes son esenciales para la estadificación de los linfomas. La utilización de la imagen funcional que proporciona la tomografía por emisión de positrones con 18F-2-deoxi-2-fluoro-D-glucosa asociada a la tomografía computarizada ha cambiado fundamentalmente el con...

Overall survival predictors in hepatocellular carcinoma patients treated with sorafenib

SUMMARY Malignant liver tumors are the fourth leading cause of cancer death worldwide. Hepatocellular carcinoma (HCC) accounts for 75-85% of these. Most patients are diagnosed at incurable stages. Palliative care is the appropriate treatment course in these circumstances (chemoembolization and sorafenib)...

Prostate cancer screening among elderly men in Brazil: should we diagnose or not?

Int. braz. j. urol; 46 (1), 2020
ABSTRACT Purpose: Prostate cancer screening in the elderly is controversial. The Brazilian government and the National Cancer Institute (INCA) do not recommend systematic screening. Our purpose was to assess prevalence and aggressiveness of prostate cancer in men aged 70 years and above, on the first La...

Increased neutrophil lymphocyte ratio and platelet lymphocyte ratio in malignant parotid tumors

Abstract Introduction Recently it has been reported that a high preoperative neutrophil-lymphocyte ratio and platelet-lymphocyte ratio may be related to increased recurrence risk, tumor aggressiveness, and worsened prognosis in various malignancies. Objective The objective of this research is to explor...

Endobronchial ultrasound-guided transbronchial needle aspiration combined with either endoscopic ultrasound-guided fine-needle aspiration or endoscopic ultrasound using the EBUS scope-guided fine-needle aspiration for diagnosing and staging mediastinal diseases: a systematic review and meta-analysis

Clinics; 75 (), 2020
The present systematic review and meta-analysis aimed to evaluate the available evidence base on endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) combined with either endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) or endoscopic ultrasound using the EBUS scope-gu...

SULF2 promotes tumorigenesis and inhibits apoptosis of cervical cancer cells through the ERK/AKT signaling pathway

Braz. j. med. biol. res; 53 (2), 2020
The objective of this study was to explore the role of the SULF2-mediated ERK/AKT signaling pathway in cervical cancer. SULF2 expression was detected in tumor tissues and tumor-adjacent normal tissues from cervical cancer patients. HeLa cells were divided into six groups: control group, NC group, SULF2 s...

FoxP3+ regulatory T cells in oral tongue squamous cell carcinoma in young and older patients

Abstract Regulatory T (Treg) cells can suppress antitumor immune response, but little is known about possible age-related differences in the number of these cells in the microenvironment of oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to determine the number of FoxP3+ Treg cells...
