During the last few decades, immunotherapy is considered to be an important approach to help our immune system to fight various kinds of diseases, such as tumor. Sometimes, it works very well for some types of cancers, for example: bladder cancer, colorectal cancer, breast cancer and lymphoma.

The gut microbiome or gut flora is a vast community of microorganisms such as bacteria, viruses, protozoa, and fungi that inhabit the digestive tract of the human and other animals. In the human body, bacterial species colonize into the oral cavity, skin, vagina, and placenta, however, the largest population of microorganisms resides in the intestine. The majority of gut microbiota belong to the phyla Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria.

In the last 10 years, the marker “Human Epididymis protein 4 (HE4)” for the management of gynecological tumors has entered powerfully in the world literature. At the moment, carrying out an accurate research in the main scientific portals such as PubMed, we can find more than 2,000 works concerning Cancer antigen-125 (Ca125), but those concerning HE4 are less than 400. The assessment of the prognostic significance of Ca125 has been described in more than 1000 scientific papers, whereas in the case of HE4 such works are only about 100.

Previous studies of in vitro and in vivo morphogenesis may suggest a more inclusive principle governing biological processes. In this regard, methylglyoxal (MG) in very low, non-toxic concentrations and ascorbic acid have been shown to promote in vitro morphogenesis in various types of plants. Forces of cohesion and adhesion might be involved in such development. These are conveyed through the electronic desaturation of protein by means of MG and ascorbic acid.

Peripheral nerves have been shown to modulate the growth and spread of tumours in the prostate, feeding both cancer cells and the stroma in the tumour environment. Several in vitro and in vivo studies have reported the effect of botulinum toxin (BT) on tumour tissue in the prostate. BT in humans has been observed to cause increased apoptosis of cancer cells, with morphological changes characterized by extensive degenerative and atrophic areas of cancer, reduced cytoplasm, and pyknotic nuclei, compared to the characteristics of cancer tissues injected with saline solution.
