Abstract

BACKGROUND/AIM:

It has been reported that oral administration of lipopolysaccharide (LPS) recovers an individual's immune condition and induces the exclusion of foreign matter, inflammation and tissue repair. We orally administered LPS from the wheat symbiotic bacteria Pantoea agglomerans, which has been ingested and proven to be safe, to cancer patients. Our observation of clinical improvements resulting from this treatment are reported.

PATIENTS AND METHODS:

Sixteen cancer patients who exhibited declined small intestinal immune competence were treated between June and September, 2015. Diagnosis was based on our evaluation on small intestinal immune competence and macrophage activity.

RESULTS:

The state of malignant tumors at 3 months after starting this treatment was complete recovery for 3 cases, remission for 7 cases, maintenance for 4 cases, exacerbation for 1 case and death for 1 case (total response rate=62.5%). Small intestinal immune competence and macrophage activity recovered in all cases, suggesting that oral administration of LPS contributes to disease improvement. No clear side-effects that appeared to be related to LPS intake were noted.

CONCLUSION:

Intake of an appropriate level of Pantoea agglomerans LPS recovers small intestinal immune competence and macrophage activity, contributing to improvement of malignant tumors' therapy.
