Introduction: There have been few studies on lymphangiogenesis in the past due to the lack of specific lymphatic endothelial markers, and lymphatic-specific growth factors. Recently, these limitations have been relieved by the discovery of a small number of potential lymphatic-specific markers. The relationship between lymphangiogenesis and regional or distant metastasis has not previously been investigated in humans. Using these lymphatic markers, it is possible to explore the relationship between lymphangiogenesis and tumour metastasis. This study indirectly quantified lymphangiogenesis by measuring mRNA expression of all seven lymphatic markers described above in breast cancers and correlated these markers with lymphatic involvement and survival.

Rectal bleeding is a good indicator of underlying colorectal disease. Most of the significant lesions presenting with this symptom are found in the left side of the colon. A nurse-led OAFS is safe, effective, and acceptable to patients. It also is more cost effective than a consultant-led service.

Abstract. This study examined the expression and distribution of BCSG-1 in human breast cancer tissue. IHC revealed that BCSG-1 was primarily seen as a cytosolic protein, weakly staining normal mammary epithelial cells but increased in breast tumour cells. Q-PCR revealed that node negative and positive tumours had similar levels of BCSG-1 transcript and BCSG-1/CK19 ratio. There were significantly higher levels in grade 2 and grade 3 tumours compared to grade 1. Patients with NPI (Nottingham prognostic indicator) <3.4, had a predicted 80% 15-year survival. After a 10-year follow-up, no significant difference was seen between tumours from patients remaining disease-free and those who died of breast cancer. The levels of BCSG-1 significantly correlated with an associated molecule, transglutaminase-3 (r=0.307, P<0.05), and weakly with transglutaminase-7 (r=0.183). BCSG-1 is increased in breast tumour cells, is negatively associated with tumour grade and significantly correlates with levels of transglutaminase-3.
