Immunohistochemical and clinicopathologic features of estrogen receptor-negative, progesterone receptor-positive, HER-2 negative breast carcinomas

SUMMARY OBJECTIVE: Currently, there is an ongoing debate whether progesterone receptor positive and estrogen receptor negative breast carcinomas represent a true distinct subtype of tumor or a mere immunohistochemical artifact. In this study, we conducted an immunohistochemistry panel with the antibodie...

Carcinoma del conducto salival: estudio clínico/patológico e inmunohistoquímico de 5 casos

El carcinoma del conducto salival es un tumor epitelial maligno agresivo, que involucra principalmente a la glándula parótida, con características histológicas semejantes al carcinoma ductal de glándula mamaria. El propósito de este trabajo fue presentar los resultados clínico-patológicos de cinc...

Prognostic and clinicopathological value of zwint expression levels in patients with lung adenocarcinoma: a systematic review and meta-analysis

Clinics; 76 (), 2021
The current study found that high Zeste White 10 interactor (ZWINT) expression is related to the poor prognosis of patients with a variety of cancers. This study mainly explored the relationship between the expression level of ZWINT and the prognosis of patients with lung adenocarcinoma (LUAD). Briefly, ...

Evaluation of squamous cell carcinoma antigen 1 expression in oral squamous cell carcinoma (tumor cells and peritumoral T-lymphocytes) and verrucous carcinoma and comparison with normal oral mucosa

J. appl. oral sci; 29 (), 2021
Abstract Background: Squamous cell carcinoma antigen (SCCA) is used as a prognostic marker for recurrence of squamous cell carcinoma in various sites, including head and neck. Studies suggest that its high serum levels are correlated to some clinical features, such as nodal metastasis. However, it is st...

Comparison of hormonal receptor expression and HER2 status between circulating tumor cells and breast cancer metastases

Clinics; 76 (), 2021
OBJECTIVES: Breast cancer (BC) is the most common neoplasm in women. Biopsy of metastatic lesions is recommended to confirm estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status as there are discrepancies in these patterns between primary tumors an...

Association of kinesin family member 2A with increased disease risk, deteriorative clinical characteristics, and shorter survival profiles in acute myeloid leukemia

Braz. j. med. biol. res; 54 (2), 2021
This study aimed to explore the correlation of kinesin family member 2A (KIF2A) expression with disease risk, clinical characteristics, and prognosis of acute myeloid leukemia (AML), and investigate the effect of KIF2A knockdown on AML cell activities in vitro. Bone marrow samples were collected from 176...

Overexpression of serum extracellular vesicle microRNA-215-5p is associated with early tumor recurrence and poor prognosis of gastric cancer

Clinics; 76 (), 2021
OBJECTIVES: Extracellular vesicle microRNAs (EV-miRNAs) have been demonstrated to be reliable candidate biomarkers for clinical applications. However, the clinical application potential of serum EV-miR-215-5p for gastric cancer (GC) remains poorly understood. The goal of our study was to determine the ef...

Perfil de citocinas Th1, Th2, Th17 y otras citocinas pro inflamatorias (IL-1β, IL-6 y TNFα) en el plasma de pacientes con cáncer gástrico

El cáncer gástrico (CG) es la neoplasia del tubo digestivo más prevalente en el mundo, asociada a factores genéticos del hospedero y externos, como infección por Helicobacter pylori. La patogénesis incluye inflamación crónica mediada por citocinas del microambiente tumoral, detectables sistémica...

Identification and clinical validation of gene signatures with grade and survival in head and neck carcinomas

Braz. j. med. biol. res; 54 (11), 2021
This study aimed to explore gene expression profiles that drive malignancy from low- to high-grade head and neck carcinomas (HNC), as well as to analyze their correlations with survival. Gene expressions and clinical data of HNC were downloaded from the Gene Expression Omnibus (GEO) repository. The signi...

Inappropriate requests for tumor markers in patients aged 50 years and older: lessons not learned

OBJECTIVE: To investigate, within a private health insurance, the ordering frequency and the costs related to inappropriate tumor markers test orders. METHODS: This study analyzed data regarding tumor markers requests within a private health insurance between 2010 and 2017. Patients included in this anal...
