Abstract  Regulatory T cells may be crucial in the development of T cell tolerance to malignancies and contribute to immune dysfunctions. We investigated the percentage, activity, and onset of apoptosis of T cell subpopulations by multicolor flow cytometry in metastatic epithelial cancer patients compared to normal controls. Furthermore, a possible relationship between the presence of circulating tumor cells detected by immunocytochemistry and immune cell abnormalities was evaluated. Our study demonstrated a significantly elevated proportion of regulatory T cells in cancer patients (p  [ABSTRACT FROM AUTHOR]

We investigated the predictive value of HER-2/neu and epidermal growth factor receptor (EGFR) in tumor tissue and prechemotherapy serum for histopathologic response in 108 patients with breast cancer undergoing neoadjuvant anthracycline-based chemotherapy.Response to chemotherapy, assessed by histopathologic classification of regression (grade 0 [no therapy effect] to 4 [no residual tumor]), correlated significantly with prechemotherapy serum HER-2/neu levels. Median prechemotherapy serum HER-2/neu levels were significantly higher in patients with regression grades 1 through 4 compared with those in patients with regression grade 0 (9.6 vs 8.55 ng/mL; P = .011; 95% confidence interval [CI], .009-.014). Median pretreatment serum HER-2/neu levels of patients with complete pathologic response (pCR) were significantly higher than in patients with moderate or no treatment response (10.95 vs 9.1 ng/mL; P = .041; 95% CI, .036-.046). Receiver operating characteristic curve analysis revealed a serum HER-2/neu value of more than 10.3 ng/mL to predict a pCR with 80% sensitivity and 69.4% specificity. There was no significant correlation of response with HER-2/neu and EGFR scores in tumor tissue or with serum EGFR levels.Results demonstrate prechemotherapy serum HER-2/neu to be a significant predictor of response to neoadjuvant anthracycline-based chemotherapy for breast cancer.

Abstract Goals of work?? This study reflects variables being depicted as predictors of global quality of life in current research. The evaluation was conducted at the Division of Clinical Oncology at the Medical University in Graz, Austria. Patients and methods?? A sample of 210 breast cancer patients between ages 30 and 80?years was assessed 1?5?years after initial diagnosis in a tumor-free stage. Besides the socio-demographic and medical variables, the Brief Symptom Inventory (BSI), Impact of Event Scale (IES), Mental Adjustment to Cancer (MAC), and the Perceived Family Support (PFS) were used. To identify variables related to quality of life, stepwise multiple regression analyses were calculated. Main results?? In a regression analysis, the general severity index (BSI) was identified as the most important and helplessness/hopelessness (MAC) as the second important variable related to QoL. Including the BSI-subscales as predictors, the depression-subscale (BSI) explained 25% of the variance; in addition, somatization (BSI), helplessness/hopelessness (MAC), and having financial problems (semi-structured interview) were significantly related to global quality of life, but the medical variables showed no associations to the measured quality of life. Depression itself is associated with negative the impact of cancer, the number of stressful life events, being uncomfortable with the body, having financial problems and anxious preoccupation (MAC). Conclusions?? The awareness of the role of multi-factorial and associated variables could provide patients, family, and medical staff with appropriate and adequate tools to treat specific symptoms.
