Tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography: association with N categories

Clinics; 71 (4), 2016
OBJECTIVE: To determine whether the gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict the presence of regional lymph node metastasis and could determine N categories. MATERIALS AND METHODS: A total of 202 consecutive patients with gastric adenocar...

Association between microRNA single nucleotide polymorphisms and the risk of hepatocellular carcinoma

Rev. méd. Chile; 144 (4), 2016
Background: Hepatocellular carcinoma (HCC) has a high morbidity and mortality. Single nucleotide polymorphisms (SNPs) of microRNA (miRNA) may be associated with the susceptibility to develop certain malignant tumors. Aim: To study the association between SNPs of miRNA and hepatocellular carcinoma in peri...

Ultrasonografía bronquial con aspiración por aguja fina en el estudio lesiones adyacentes a la vía aérea central

Rev. méd. Chile; 144 (3), 2016
Background: Endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a high diagnostic yield for lesions adjacent to the central airway. Aim: To describe the diagnostic yield of EBUS-TBNA for lesions suspicious of Non-Small Cell Lung Cancer (NSC...

White blood cell counts and neutrophil to lymphocyte ratio in the diagnosis of testicular cancer: a simple secondary serum tumor marker

Int. braz. j. urol; 42 (1), 2016
ABSTRACT Purpose The aim of the study was to investigate white blood cell counts and neutrophil to lymphocyte ratio (NLR) as markers of systemic inflammation in the diagnosis of localized testicular cancer as a malignancy with initially low volume. Materials and Methods Thirty-six patients with local...

Three-dimensional reconstructive kidney volume analyses according to the endophytic degree of tumors during open partial or radical nephrectomy

Int. braz. j. urol; 42 (1), 2016
ABSTRACT Objectives To investigate the renal function outcomes and contralateral kidney volume change measured by using a 3-dimensional reconstructive method after open partial nephrectomy (PN) or open radical nephrectomy (RN) according to the endophytic degree of tumors. Materials and Methods We inc...

Immunohistochemical analysis of FoxP3+ regulatory T cells in lower lip squamous cell carcinomas

Braz. oral res. (Online); 30 (1), 2016
Abstract: The aim of this study was to determine the number of FoxP3+ regulatory T (Treg) cells in the microenvironment of lower lip squamous cell carcinomas (LLSCCs) and to correlate the findings with clinicopathological parameters (tumor size/extent, regional lymph node metastasis, clinical stage, and ...

The anti-cancerous activity of recombinant trichosanthin on prostate cancer cell PC3

Biol. Res; 49 (), 2016
CONTEXT: Trichosanthin produced in the root tube of Trichosanthes kirilowii shows anti-tumor activity on a series of cancer cells including Hela, MCF-7, HL-60. But there is little information about its effect on the carcinogenesis of prostate cancer. OBJECTIVE: This work was designed to study the role of...
