Circulating levels of galectin-9 are a potential biomarker of survival in advanced non-small-cell lung cancer.

Background: The immune system is recognized to have therapeutic potential to destroy cancer cells. Soluble T-cell immunoglobulin mucin domain-3 (sTIM-3) and its ligand galectin 9 (Gal-9) cause suppression of cytokine production, cell cycle arrest and cell death. sTIM-3 and Gal-9 levels may have prognostic implications in non-small-cell lung cancer (NSCLC) patients.

Immune checkpoint expression as prognostic biomarker candidates in non-small cell lung carcinoma patients.

Background: Cancer immunotherapy has had an important role in oncologic therapeutics for patients with non-small cell lung cancer (NSCLC) using checkpoint inhibitors. We will explore the possible prognosis biomarker candidates such as: soluble OX40 (sOX40), OX40L (sOX40L), Glucocorticoid-induced tumor necrosis factor receptor family-related receptor (GITR), and their ligand (GITRL), 4-1BB or tumor necrosis factor receptor superfamily 9 (TNFRS9) and inducible T cell co-stimulator (ICOS) in peripheral blood of NSCLC patients.

Methods: Fifty-eight patients were diagnosed with advanced NSCLC between January 2019 and March 2020.

Expression of CD28, FAS, PD1, and CTLA4 molecules in the blood of women with triple-negative breast cancer.

Background: Locally advanced triple-negative breast cancer (TNBC) represents a public health problem in Brazil. Its standard treatment consists of neoadjuvant chemotherapy (NAC).

Methods: This was a longitudinal study with follow-up performed between the years 2015 and 2017.

Prognostic role of SOX2 and STAT3 expression on circulating T lymphocytes and CD44+/CD24 cells in the locally advanced and metastatic breast cancer.

Background: Breast cancer (BC) is associated with a continuous increase in incidence, with high mortality rates in several countries. CD44, STAT3, and SOX2 are related to regulating of somatic cell division, tumorigenesis, and metastasis in BC.

Methods: A cross-sectional study was carried out at the Hospital de Cancer de Pernambuco (HCP) between 2017 and 2018.

Immunopositivity for Siglec-15 in gastric cancer and its association with clinical and pathological parameters.

The sialic acid-binding immunoglobulin-type lectin Siglec-15 is a promising target to cancer immunotherapy in several tumor types. The present study aimed to investigate Siglec-15 expression in gastric cancer (GC) patient tissue and to evaluate its clinical value. Siglec-15 expression was evaluated by immunohistochemistry with 71 patients.

Assessment of the gustatory function in patients with advanced oral cavity and oropharyngeal cancer.

Purpose: The changes in gustatory function resulting from oncological treatment occur mainly after radiotherapy. However, the head and neck tumors, because of the anatomical location of the lesion, can themselves trigger significant changes in the feeding-related functions - including taste. To assess the gustatory function in patients diagnosed with advanced oral cavity and oropharyngeal cancer.

Overexpression of UDP-Glucose 4-Epimerase Is Associated with Differentiation Grade of Gastric Cancer.

The UDP-glucose 4-epimerase (GALE) is a glycosyltransferase, which acts on protein and lipid glycosylation in normal and neoplastic cells. This study is aimed at investigating the differential tissue expression of GALE and its possible association with clinical-pathological parameters and the outcome of gastric adenocarcinoma patients. Seventy-one patients were evaluated in relation to GALE expression by immunohistochemistry.

Is oxidized low-density lipoprotein the connection between atherosclerosis, cardiovascular risk and nephrolithiasis?

Nephrolithiasis is considered a systemic disease. A link has been established between nephrolithiasis, cardiovascular disease (CVD), the metabolic syndrome and atherosclerosis. A significant correlation has been found between the high levels of oxidized low-density lipoprotein (oxLDL) and CVD and atherosclerosis, including coronary and femoral artery disease.

Serum protein concentration in low-dose total body irradiation of normal and malnourished rats.

Among the radiotherapeutics' modalities, total body irradiation (TBI) is used as treatment for certain hematological, oncological and immunological diseases. The aim of this study was to evaluate the long-term effects of low-dose TBI on plasma concentration of total protein and albumin using prematurely and undernourished rats as animal model. For this, four groups with 9 animals each were formed: Normal nourished (N); Malnourished (M); Irradiated Normal nourished (IN); Irradiated Malnourished (IM).

A PHASE II TRIAL EXPLORING THE EXTENSIVE INTRA-OPERATIVE PERITONEAL LAVAGE (EIPL) AS A PROPHYLACTIC STRATEGY FOR PERITONEAL RECURRENCE IN LOCALLY ADVANCED GASTRIC CANCER: reporting postoperative morbidity and mortality after early closure.

Background: The Extensive Intraoperative Peritoneal Lavage (EIPL) has been proposed as a practical prophylactic strategy to decrease the risk of peritoneal metastasis in gastric cancer.

Objective: To explore the safety and efficacy of the EIPL in our locally advanced gastric cancer patients.

Methods: This study is an open-label, double-center, single-arm phase II clinical trial developed at two tertiary hospitals from Recife (Pernambuco, Brazil).
