Abstract
The gene profile of primary tumors, as well as the identification of circulating tumor cells (CTCs), can provide important prognostic and predictive information. In this study, our objective was to perform tumor gene profiling (TGP) in combination with CTC characterization in women with nonmetastatic breast cancer. Biological samples (from peripheral blood and tumors) from 167 patients diagnosed with stage I, II, and III mammary carcinoma, who were also referred for adjuvant/neoadjuvant chemotherapy, were assessed for the following parameters: (a) the presence of CTCs identified by the expression of CK-19 and c-erbB-2 in the peripheral blood mononuclear cell (PBMC) fraction by quantitative reverse transcription PCR (RT-PCR) and (b) the TGP, which was determined by analyzing the expression of 21 genes in paraffin-embedded tissue samples by quantitative multiplex RT-PCR with the Plexor® system. We observed a statistically significant correlation between the progression-free interval (PFI) and the clinical stage (p = 0.000701), the TGP score (p = 0.006538), and the presence of hormone receptors in the tumor (p = 0.0432). We observed no correlation between the PFI and the presence or absence of CK-19 or HER2 expression in the PBMC fraction prior to the start of treatment or in the two following readouts. Multivariate analysis revealed that only the TGP score significantly correlated with the PFI (p = 0.029247). The TGP is an important prognostic variable for patients with locoregional breast cancer. The presence of CTCs adds no prognostic value to the information already provided by the TGP.

Abstract
Background Fatigue is common in cancer patients receiving adjuvant chemotherapy. To further understand the mechanism of fatigue and search for potential biomarkers, we conducted this prospective study. Methods We enrolled breast cancer (BC) patients before their first adjuvant Adriamycin-based chemotherapy cycle. Patients responded to the brief fatigue inventory (BFI) and Chalder fatigue questionnaires and had their blood drawn for both plasma evaluation and evaluation of the peripheral mononuclear cell fraction (PMNCF) mRNA expression of various biomarkers. We evaluated FSH, LH, estradiol, DHEA, DHEAS, IL6, IL2, ILIRA, IL1β, CRP, Cortisol in the plasma and IL2, IL10, IL6, TGF-β, KLRC1, TNF, BTP, SNCA, SOD1, BLNK, PTGS2 and INF γ expression in the PMNCF. Results 11 patients did not exhibit an increase in their BFI scores and served as controls, whereas 32 patients exhibited an increase in their BFI scores compared with the baseline scores. From the biomarkers we evaluated in the PMNCF, the only one significantly associated with fatigue was TGF-β (p = 0.0343), while there was a trend towards significance with KLRC1 (p = 0.0627). We observed no evidence of significant associations of any plasma biomarkers with the development of fatigue. However when we analyzed patients with more severe fatigue, plasma IL1-RA levels correlated directly with higher fatigue scores (p = 0.0136). Conclusions We conclude that fatigue induced by chemotherapy in BC patients is associated with changes in IL1-ra plasma levels and in TGF-β lymphocyte expression. Its mechanism may be different than that observed in long-term BC survivors or that induced by radiation therapy. Trial registration NCT02041364 [ClinicalTrials.gov]

Abstract
Breast cancer (BC) is the second most common cancer worldwide and the first among women. If early diagnosed and treated, this disease has a good prognosis. However, it is believed that 90 % of all patients who have had cancer died due to metastatic disease, which highlights the need for a marker which allows the detection of latent cancer cells spread from the primary tumor. The objective of this study was to investigate the expression of survinin in peripheral blood of patients with breast cancer at diagnosis and during chemotherapy aiming correlation with minimal residual disease, clinical and pathological findings. The study included 40 patients with breast cancer and 12 healthy donors as a comparison group. Survinin expression was verified by real-time PCR. For diagnosis, survinin expression cutoff point was 1.05; considering this cutoff point, we obtained a test sensitivity of 85.3 %, specificity of 75.0 %, positive predictive value of 90.6 %, negative predictive value of 64.3 %, and accuracy of 82.6 %. There was statistical significance between groups (patients × control group), presenting to patients a significantly higher value than the control group (p < 0.001). Patients that presented at the diagnosis a survinin gene expression ≥ 1.05 are 17 times more likely to develop metastatic disease.

Abstract
BACKGROUND Hyperhomocysteinemia in breast cancer (BC) patients can be a risk factor for thromboembolic events. This study aimed to evaluate homocysteine and its cofators (folic acid and vitamin B12) concentrations and platelet count at diagnosis of BC, 3 and 6 months after the beginning of chemotherapy treatment and to correlate them with clinical data. METHODS Thirty-five BC patients were included; blood samples were obtained by venipuncture. Plasmatic Hcy and cofactors concentrations were measured by competitive chemiluminescent enzyme immunoassay method. Platelet count was done using an automated analyzer. Statistical analysis was performed using the software SPSS. RESULTS During chemotherapy, homocysteine (P = 0.032) and vitamin B12 (P < 0.001) concentrations increased, while folate and platelets decreased (P < 0.001). Among the clinical data, the menopausal status showed significant positive correlation (P = 0.022) with homocysteine concentration increase. CONCLUSIONS Evaluation of homocysteine concentrations during chemotherapy is extremely important because their levels increase during chemotherapy treatment, thus increasing the risk of thromboembolism development.

Abstract
Trypanosoma cruzi lipids contain a high content of unsaturated fatty acids, primarily oleic acid (C18:1) and linoleic acid (C18:2). Previous data suggest that this parasite is able to convert oleic acid into linoleic acid; humans are not able to do this. Presently, we show that T. cruzi has a gene with high similarity to the delta12 (omega6)-oleate desaturase from plants. Northern blot analysis of the oleate desaturase gene from T. cruzi (OD(Tc)) indicated that this gene is transcribed in epimastigote, amastigote, and trypomastigote forms. Pulsed-field analysis showed that OD(Tc) is located at distinct chromosomal bands on distinct T. cruzi phylogenetic groups. In addition, the chromoblot analysis demonstrated the presence of homologous OD(Tc) genes in several trypanosomatids; namely, Crithidia fasciculata, Herpetomonas megaseliae, Leptomonas seymouri, Trypanosoma freitasi, Trypanosoma rangeli, Trypanosoma lewisi, Blastocrithidia sp., Leishmania amazonensis, Endotrypanum schaudinni, and Trypanosoma conorhini. The native OD(Tc) activity was detected by metabolic labeling and analysis of total fatty acids from epimastigotes and trypomastigotes of T. cruzi, coanomastigotes of C. fasciculata, and promastigotes of L. amazonensis, H. megaseliae, and L. seymouri. The fact that the enzyme oleate desaturase is not present in humans makes it an ideal molecular target for the development of new chemotherapeutic approaches against Chagas disease.
