  1. Inherited failure is solely in tumour cells

    In a previous comment posted on the BioMedCentral web site (Stagnaro S., Genes and Cancer: a clinical view-point. The Oncological Terrain., I referred to a working hypothesis conceived a long time ago: all chromosomal alterations, of whatever nature, both n-DNA and m-DNA, are necessarily accompanied by similar structural and functional modifications of the local microcirculatory bed in subjects with abnormalities of the pschyco-neuro-endocrine-immune system, i.e. in the biological control system for malignancy that I defined as the Oncological Terrain. In fact, both genetic and environmental factors, e.g. estrogen therapy, induce alterations in the parenchymal and microvascular cells concurrently according to the well-known concept of Tiscendorf’s Angiobiotopie, which I completed with a new concept of Angiobiopathy [1, 2]. Briefly, all cell-dependent oncological events (control, regulation, duplication etc.) may occur only by means of singular changes in the local structural and functional microcirculation, which is well known to supply information-material-energy to related tissue cells (see my web site and particularly the linked site All these pathological events occur only in well-localized sites of the biological system. In contrast, all the other cells that surround the first are perfectly normal. Thanks to Biophysical Semeiotics, we can nowadays evaluate the structure and function of the microcirculatory bed clinically and precisely in breast cancers and all other biological systems, including lymph nodes and bone-marrow, assessing local vasomotility and vasomotion clinically [1-6]. By properly evaluating the type of microcirculatory activation of breast cancer as well as of lymph nodes and bone-marrow (type I, associated, physiological; type II, intermediate, partially dissociated, characteristic of real oncological risk; and finally type III, dissociated, indicating cancer onset), we can quantitatively evaluate alterations in the physiological relationship between vasomotility (= chaotic deterministic oscillations of small arterioles and arterioles, according to Hammersen) on the one hand, and vasomotion (= chaotic deterministic oscillations of related capillary and post-capillary primary venules) on the other, since the intensity of e.g. dissociation is correlated with the seriousness of underlying oncological disorders. 1.
