The Expression of CTLA-4 in Breast Tumors and Tumor-Infiltrating Leukocytes Affects Patients' Systemic Inflammatory Status and Varies According to Their Molecular Subtypes.

Recent evidence has pointed out that the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expression is a poor prognosis factor. However, the implications of CTLA-4 expression on circulating inflammatory mediators are unclear for breast cancer. Tumor biopsies and blood samples were collected from 117 breast cancer patients.

A qualitative analysis of denture wearing experience affecting the quality of life of older adults.

Objective: To explore how denture-related experiences affect older adults' quality of life using a qualitative assessment of the Oral Health Impact Profile for Edentulous individuals (OHIP-Edent).

Materials And Methods: Twenty elderly individuals were interviewed before and 3 months after delivering new complete dentures, using an open-ended interview guide based on the OHIP-Edent. Interviews were audio-recorded and transcribed.

Occupational Exposure to Pesticides Affects Pivotal Immunologic Anti-Tumor Responses in Breast Cancer Women from the Intermediate Risk of Recurrence and Death.

Breast cancer risk stratification is a strategy based using on clinical parameters to predict patients' risk of recurrence or death, categorized as low, intermediate, or high risk. Both low and high risk are based on well-defined clinical parameters. However, the intermediate risk depends on more malleable parameters.

CTLA-4 Expression and Its Clinical Significance in Breast Cancer.

Breast cancer is the leading cause of women's death among all cancers. The main reason associated with this is the development of metastasis and therapy-resistant breast carcinoma (BC), which pose the main challenge of oncology nowadays. Evidence suggest that these tumors seem to have inhibitory mechanisms that may favor their progression and surveillance.

Effects of GSTT1 and GSTM1 polymorphisms in glutathione levels and breast cancer development in Brazilian patients.

Polymorphisms in the glutathione transferase enzymes (GSTs) genes have been associated with susceptibility to develop breast cancer (BC), but few are known regarding its role on this disease prognosis and impact on antioxidant status. This study evaluated the polymorphisms of GSTM1 and GSTT1 genes and their relationship with BC susceptibility and prognostic, as well as its impact on plasma reduced glutathione (GSH) levels. The present study included 121 women with invasive ductal BC and 151 healthy controls.

Current advances in the diagnosis and personalized treatment of breast cancer: lessons from tumor biology.

Breast cancer treatment has advanced enormously in the last decade. Most of this is due to advances reached in the knowledge regarding tumor biology, mainly in the field of diagnosis and treatment. This review brings information about how the genomics-based information contributed to advances in breast cancer diagnosis and prognosis perspective, as well as presents how tumor biology discoveries fostered the main therapeutic approaches available to treat such patients, based on a personalized point of view.

Low Plasmatic 25-hydroxyvitamin D at Diagnosis is Associated with Axillary Invasion, Chemoresistance and Metastasis in Women with Breast Cancer.

Purpose: In this study, we investigated the circulating levels of 25-hydroxyvitamin D (25[OH]D) in Brazilian women with breast cancer in samples collected at diagnosis, and correlated these with clinicopathological parameters relevant to disease prognosis.

Methods: This study involved 147 women diagnosed with infiltrative ductal carcinoma whose peripheral blood samples were collected, to have 25(OH)D levels measured in plasma.

Results: Our findings indicated that circulating 25(OH)D levels at diagnosis were insufficient in patients with breast cancer.
