by Standardized Plant Immunomodulatory Preparations
Tibor Hajto1,* and Angelika Kirsch2 1Department of Immunology and Biotechnology, University Pecs, Faculty of Medicine, Pecs, Hungary 2Private Praxis, Paradiesstr. 14, Binningen CH-4102, Switzerland Abstract: Background: Metastatic hepatocellular carcinoma often has a multifocal tumor pattern with markedly
depressed hepatic function. Hepatic resection in many cases results in no long-term benefit. After a chemotherapy
hepatic tumors rarely disappear completely and the duration of responses is short. In the last decades growing evidence
suggested that a disturbed balance in the innate system can also play a role in the poor prognosis of hepatic tumors.
Objectives: The aim of this article is to present and discuss several favorable clinical responses of patients with hepatic metastases who parallel to conventional oncologic therapy, were treated with immunologically effective and standardized plant extracts. Course of Therapy and Results: In accordance with the bell-shaped dose-response relationship of mistletoe lectins (MLs), the patients were treated with a fermented mistletoe extract (ME) preparation, standardized for the active sugar-binding lectin contents. Thus, an optimal dose between 0.5 and 1.0ng/kg MLs was given twice a week subcutaneously. In addition to ML therapy, a heteropolysaccharide rice bran preparation standardized for arabinoxylan (12-45mg/kg MGN-3/Biobran twice a week) and wheat germ extract (WGE) standardized for 2, 6-dimethoxy-p-benzoquinone (50- 80mg/kg Avemar four times a week) was also given. In these case reports the clinical progress of seven patients showed a complete or nearly complete remission of hepatic metastases. Conclusion: ML, MGN-3 and WGE seem to be potent candidates to be regarded as a supportive therapy to surgery, hormone treatment or chemotherapy for patients with hepatic metastases. These case reports require further clinical studies. Keywords: Hepatic metastasis, immunomodulation, mistletoe extract, mistletoe lectin, arabinoxylan, MGN-3, wheat

All patients received other organs. Median survival was mostly found to be mistletoe extracts (ME) standardized in term of very short (four to six months). Operative procedures, mistletoe lectins (ML) given in appropriate doses, which which generally entail lobectomy or segmentectomy, were shown to induce the most effective improvement are associated with considerably better survival rates in cancer-related disarray of the immune balance [9- [1]. However, most patients with hepatocellular 12].
