Expression profiling of angiogenic genes for the characterisation of colorectal carcinoma.

The development of new blood and lymphatic vessels is a crucial event for cancer growth, metastatic spread and relapse after therapy. In this work, the expression levels of chemokines, angiogenic and angiostatic factors and their receptors were determined in paired mucosal and tumour samples of patients with colorectal carcinoma and correlated with clinical and histological parameters by advanced multivariate analyses. The most important predictors to discriminate between tumour and paired normal mucosa turned out to be the levels of expression of plexin-A1 and stromal cell-derived factor 1 (SDF-1), the former overexpressed and the latter downregulated in tumours.

[Inflammatory pseudotumour of the liver: case report and review of the literature].

We report a case of inflammatory pseudotumour of the liver in a 53-year-old woman who over the previous month had presented malaise, fever and right-sided hypochondralgia. On physical examination the liver was tender at palpation 2 cm below the right costal margin. Laboratory data were normal.
