Fructosamine and glycated hemoglobin as biomarkers of glycemic control in people with type 2 diabetes mellitus and cancer (GlicoOnco study).

Introduction: Glycemic control is important to avoid diabetes complications in individuals with cancer. There is no evidence for HbA1c and fructosamine as reliable biomarkers in these conditions. There are particularities in caring for patients with diabetes and cancer that can alter these biomarkers.

Variability of high-dose melphalan exposure on oral mucositis in patients undergoing prophylactic low-level laser therapy.

The present study outlines the clinical impact and risk factors of oral mucositis in 79 patients with multiple myeloma following high-dose melphalan for autologous transplant. All patients underwent daily prophylactic low-level indium gallium aluminum phosphate diode laser therapy (660 nm, 15 mW, 3.75 J/cm, 10 s per point) from the beginning of the conditioning regimen up to day +2.

Altered expression of apoptosis-regulating miRNAs in salivary gland tumors suggests their involvement in salivary gland tumorigenesis.

Salivary gland tumors comprise a heterogeneous group of lesions with different histological features and diverse clinical pathophysiology. They account for about 3% of all head and neck tumors. Apoptosis plays an important role during morphogenesis of glandular structures, including that of the salivary gland.

Expression of stem cell markers in oral cavity and oropharynx squamous cell carcinoma.

Objectives: The aim of this study was to analyze the expression of CD24, CD44, CD133, ALDH1, CD29 (integrin-β1), and Ki-67 in squamous cell carcinoma of the oral cavity and oropharynx.

Study Design: Fifty-two tumors and 21 metastatic lymph nodes were evaluated by using immunohistochemistry.

Results: Seven of 52 cases (13.

Expression of stem cell-regulating miRNAs in oral cavity and oropharynx squamous cell carcinoma.

Background: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common tumor worldwide and is histologically heterogeneous. Studies have demonstrated the presence of stem cell markers in HNSCC, and microRNAs (miRNAs) have emerged as powerful regulators of differentiation, controlling the self-renewal of stem cells. miRNAs are non-coding RNA molecules that regulate gene expression post-transcriptionally.

Metastatic area ratio can help predict nonsentinel node positivity in melanoma patients.

Several studies suggest that melanoma patients with a positive sentinel node biopsy (SNB) can avoid having complete nodal dissection on the basis of pathological features of the node. The aim of the study was to determine the value of metastatic area ratio as a predictive factor for nonsentinel node (NSN) positivity. A retrospective analysis was carried out of melanoma patients who underwent SNB in a single institution between 2000 and 2010.

Evaluation of melanoma features and their relationship with nodal disease: the importance of the pathological report.

Background: The pathological features of melanoma biopsies can provide significant prognostic information that can help the surgeon evaluate the risk of nodal disease. The aim of this study was to attempt to determine the relationship between pathological features of primary melanoma and nodal disease, by sentinel node biopsy (SNB) and complete node dissection (CND).

Methods: A retrospective analysis was completed of patients who underwent SNB at AC Camargo Cancer Center, São Paulo, Brazil, between 2000 and 2010.

Benefits of an intraoral stent in decreasing the irradiation dose to oral healthy tissue: dosimetric and clinical features.

Objective: To determine whether an intraoral stent may decrease radiation dose to health tissues during intensity-modulated radiotherapy (IMRT) and to evaluate the effect on mucositis.

Study Design: A total of 33 patients with tongue or floor of the mouth cancer were retrospectively evaluated and divided into 2 groups: group 1 (with stent, n = 19) and group 2 (without stent, n = 14). Data were collected on dosimetric and mucositis outcomes.

Is DWI/ADC a useful tool in the characterization of focal hepatic lesions suspected of malignancy?

Objective: Apparent diffusion coefficient (ADC) values calculated through magnetic resonance imaging have been proposed as a useful tool to distinguish benign from malignant liver lesions. Most studies however included simple cysts in their analysis. Liver cysts are easy to diagnose, have very high ADC values and their inclusion facilitates differentiation in the ADC values between benign and malignant liver lesions groups.

Interobserver agreement rate of the spontaneous breathing trial.

Purpose: During the mechanical ventilation weaning process, the spontaneous breathing trial (SBT) is the confirmatory test of patients' capability to breathe unassisted. However, the SBT interobserver agreement rate (its reliability) is unknown, and our objective was to evaluate it.

Materials And Methods: This is a prospective, multicentric and observational study.
