Polyamines (putrescine, spermidine and spermine) as well as γ- and α-synucleins are currently the subject of a special comprehensive study due to their direct influence on the formation of neoplastic processes. This review article presents informative data on the role of aliphatic polyamines (putrescine, spermidine, spermine) in the induction of a number of oncological diseases with their localization in the digestive and urinary systems. Aspects related to the synthesis and aggregation of

The article provides information on the possible prevention of further growth of malignant cells, by inhibiting enzymatic processes responsible for the polyamine synthesis. In case of prolonged persistence of Helicobacter Pylori in the stomach, an enhanced synthesis of polyamines and cumulation in situ of oligo- and aggregated gamma synucleins occurs in mucous membrane cells. It is possible that all of the abovementioned factors in total directly and/or indirectly have a stimulating effect on the processes of the malignancy of gastric mucosal cells. The subject of special discussion was the latest literature data, according to which, under the conditions of Helicobacter Pylori persistence in the digestive tract organs, in the gastric mucosal cells an enhanced synthesis of putrescine occurs, high concentrations of which can have a co-carcinogenic effect on normally functioning target cells. From a qualitatively new point of view, the fact of cumulation in malignantly reborn cells of an aggregated gamma synuclein, which was found during Helicobacter Pylori infection, should be considered.
