Cell membrane CD44v6 levels in squamous cell carcinoma of the lung: association with high cellular proliferation and high concentrations of EGFR and CD44v5.

Membranous CD44v6 levels in tumors and surrounding samples obtained from 94 patients with squamous cell lung carcinomas were studied and compared to clinical stage, cellular proliferation, membranous CD44v5 levels, epidermal growth factor receptor EGFR and cytoplasmatic concentrations of CYFRA 21.1. CD44v6 positive values were observed in 33/38 non-tumor samples and in 76/94 tumor samples, but there were not statistically significant differences between both subgroups.

Histological grade (HG) in invasive ductal carcinomas of the breast of less than 1 cm: clinical and biological associations during progression from HG1 to HG3.

Aim: To study the clinical and biological (cellular proliferation and hormone-dependence) associations during the progression of histological grade (HG), from HG1 to HG3, in invasive ductal carcinomas of the breast (IDC) <1 cm.

Patients And Methods: The study group included 119 women with IDCs ≤1 cm, aged between 27 and 88 years (median=61 years). The parameters analyzed were: histological grade (HG1: 52; HG2: 45; HG3: 22); axillary lymph node involvement (N); distant metastasis (M); and immunohistochemical expression of estrogen (ER), progesterone (PR) and androgen (AR) receptors, and Ki67, p53 and B-cell lymphoma 2 (BCL2).

CA15.3 serum concentrations in older women with infiltrating ductal carcinomas of the breast.

Breast cancer is currently becoming a disease of the elderly. We have studied the relation between CA 15.3 serum concentrations and clinical-pathological parameters in 69 women with IDC aged over 70 years (76.

Positive immunohistochemical expression of bcl-2 in hormone-independent breast carcinomas is associated with a greater lymph node involvement and poor outcome.

To study the immunohistochemical expression of bcl-2 in patients with hormone-independent breast infiltrating ductal carcinomas (IDC) and its possible association with other clinico-biological parameters and outcome. Our study group included 72 females with hormone-independent (ER and PgR negative) infiltrating ductal breast carcinomas. Age, tumor size, axillary lymph node involvement (N), distant metastasis and histological grade, as well as the immunohistochemical expression of Ki67, p53 and androgen receptor (AR), were analyzed.

Alcohol-related social consequences in Castille and Leon, Spain.

Background: The purpose of this study was to examine the prevalence of alcohol-related social problems, as well as to assess the relationship between alcohol-related social problems and patterns of alcohol consumption in the general population during the year 2004.

Methods: A total of 2,500 individuals, age range from 14 to 70 years, in Castille and Leon, Spain, were surveyed in 2004 for their patterns of alcohol consumption and alcohol-related social consequences during the previous year.

Results: Participants who admitted to having had some kind of social problem related to the consumption of alcohol in the previous year were 6.
