RESUMEN
ABSTRACT Cancer is a multifactorial disease and a serious public health problem. Currently, alternative drug treatments for cancer are actively being sought, which is the case of synthetic phosphoethanolamine (PHOS-S), a compound that could possibly have anticarcinogenic effects. To analyze the available scientific evidence to evaluate the anticarcinogenic effects of in vivo and in vitro PHOS-S. A systematic literature review of scientific articles aimed at evaluating the anticarcinogenic potential of PHOS-S, in vivo and in vitro, using the databases PubMed, ScienceDirect, SciElo, CAPES Portal and LILACS. The selected papers suggest a possible anticarcinogenic effect of PHOS-S by inhibiting tumor growth by inducing apoptosis and cell cycle blockade as well as cytotoxic potential against leukemia cells. However, a possible stimulatory effect of tumor growth was also observed. Although some of the evaluated studies indicated a possible anticarcinogenic effect of PHOS-S, the limitations of these studies must be evaluated. Most were performed by the same research group, and in the scientific literature, we identified only preclinical studies (in cells or in animals). No human study has been published. Thus, more studies are needed to confirm the anticarcinogenic capacity of PHOS-S.
