Implementation of a Screening Program for High-Grade Anal Dysplasia in High-Risk Patients in a Tertiary Cancer Center.

Introduction: The incidence of anal squamous cell carcinoma (SCC) has been increasing over the last decades. Human papillomavirus (HPV) infection accounts for more than 90% of anal cancers, and HIV co-infection increases the risk of invasive cancer. Men who have sex with men (MSM) with HIV are the highest risk group for developing anal high-grade squamous intraepithelial lesions (aHSILs), which can be found in 45%-50% of these patients and are precursor lesions for invasive cancer.

Methodology: Microdata from the National Health Survey in 2013 and 2019 are used to estimate conditional and unconditional price elasticities of cigarette consumption in the licit and illicit cigarette markets by income quartiles and age cohorts.

Carbon Storage in Different Compartments in Eucalyptus Stands and Native Cerrado Vegetation.

This study evaluated Carbon (C) storage in different compartments in eucalyptus stands and native Cerrado vegetation. To determine C above ground, an inventory was carried out in the areas where diameter at breast height (DBH), diameter at base height (Db), and total tree height (H) were measured. In the stands, the rigorous cubage was made by the direct method, and in the native vegetation, it was determined by the indirect method through an allometric equation.

Primary colorectal diffuse large B-cell lymphoma: A report of eighteen cases in a tertiary care center.

Primary colorectal diffuse large B-cell lymphoma (DLBCL) is very rare colon malignancy. It is important to know the main demographic and clinical characteristics of these patients. We conducted a retrospective analysis of 18 patients diagnosed with primary colorectal DLBCL during a 17-year period at the National Cancer Institute of Brazil (INCA) between 2000 and 2018.
