“Background Angiogenesis is a prerequisite for tumour development, progression and metastasis; however, its underlying molecular mechanisms in endometrial carcinoma are poorly understood.\n\nDesign In this study, the mRNA and protein expression profiles of two key regulators of angiogenesis, vascular endothelial growth factor (VEGF) and transforming growth factor beta-1 (TGFB1), were evaluated by real-time PCR and western blot analysis in 23 endometrial cancer tissue-paired specimens (malignant vs. adjacent normal tissues). We aimed to investigate whether VEGF and TGFB1 serve as markers of the malignant transformation of the endometrium and whether VEGF GDC-0941 clinical trial or TGFB1 expression can constitute a useful prognostic
ARN-509 marker of survival in patients with endometrial carcinoma.\n\nResults
Tissue-pair analysis revealed VEGF transcriptional up-regulation and TGFB1 mRNA down-regulation as the most frequent transcriptional features. VEGF and TGFB1 mRNA were positively correlated (P < 0.001). VEGF protein levels were higher in endometrioid-type tissue pairs (P = 0.047). TGFB1 protein and mRNA levels were negatively correlated (P = 0.042). TGFB1 protein expression was related to survival only in patients with endometrioid adenocarcinoma (P = 0.045).\n\nConclusions Tissue-pair mRNA and protein analysis reveals VEGF transcriptional up-regulation and TGFB1 down-regulation that are correlated with the malignant transformation of the endometrium, while post-transcriptional mechanisms control VEGF and TGFB1 protein. TGFB1 protein demonstrated a prognostic value only in endometrioid adenocarcinoma.”
“Background:
this website In stage III colorectal cancer (CRC), adjuvant chemotherapy (CT) is usually prescribed within two months after curative surgery. Whether or not delaying initiation of CT affects survival is still debated.\n\nMaterial and methods: We performed a meta-analysis (MA) of all published studies (full papers or abstracts) comparing delayed CT with standard care. Studies were obtained from a PubMed query (keywords: CRC, adjuvant treatment, delay of CT), a review (Chau et al., 2006), cross-checking references and abstracts from the proceedings of ASCO, ASCO GI and WCGI annual meetings. We chose a cutoff delay of 8 weeks. Risk Ratios (RRs) were calculated from the recorded events (deaths, relapses). We used EasyMA software (fixed-effect model).\n\nResults: Fourteen studies (including four abstracts) were identified (17,645 patients; 5952 males, 5151 females, mean age 70 years). Of these, three could not be statistically analysed and three used another cutoff (4, 5 or 6 weeks), leaving 8 studies for main MA (13,158 patients; 3932 males, 3644 females, 5942 missing data; 5576 colon cancers, 6677 rectal, 1265 missing data). Delaying CT more than 8 weeks was associated to worse Overall Survival (OS) (RR: 1.20; 95% Confidence Interval (CI) 1.15-1.26).
