The high pH therapy for cancer tests on mice and humans.
Brewer AK.
Mass spectrographic and isotope studies have shown that potassium, rubidium, and especially cesium are most efficiently taken up by cancer cells. This uptake was enhanced by Vitamins A and C as well as salts of zinc and selenium. The quantity of cesium taken up was sufficient to raise the cell to the 8 pH range. Where cell mitosis ceases and the life of the cell is short. Tests on mice fed cesium and rubidium showed marked shrinkage in the tumor masses within 2 weeks. In addition, the mice showed none of the side effects of cancer. Tests have been carried out on over 30 humans. In each case the tumor masses disappeared. Also all pains and effects associated with cancer disappeared within 12 to 36 hr; the more chemotherapy and morphine the patient had taken, the longer the withdrawal period. Studies of the food intake in areas where the incidences of cancer are very low showed that it met the requirements for the high pH therapy.

BACKGROUND: The downstream effects of pH modulation significantly impact the biological fate of chemotherapeutic agents and tumor responsiveness to therapy. We have studied the effects of cesium chloride (CsCl) on pH modulation and subsequent vitamin D treatment in vitamin D receptor (VDR) positive LNCaP tumors and VDR null MDA/LCC6 tumors in vivo. METHODS: Mice bearing LNCaP or MDA/LCC6 tumors were dosed orally with CsCl (150 mg/kg) or vitamin D (1 microg/kg) alone and in combination. Tumor volume and serum PSA (LNCaP only) were measured and intracellular pH was determined, using magnetic resonance spectroscopy (MRS), at tumor and leg muscle sites. Atomic absorption spectroscopy (AAS) was used to quantitate cesium in serum, organs, and tumor tissues. RESULTS: From day 10 onwards, statistically significant (P<0.01) differences were observed in all LNCaP treated groups as compared with control. CsCl co-administered with vitamin D, caused an apparent sensitization of efficacy in this tumor model. There were no correlating differences in serum PSA. Elevation of pH was statistically significant for all three treatment groups as compared with control. The pH measured in leg muscle was not influenced by CsCl treatment. Inhibition of tumor growth was not apparent in VDR null MDA/LCC6 tumors although intracellular tumor pH was shifted. Cesium was rapidly absorbed into serum and present in LNCaP tumors, prostates and other tissues after 1 hr, remaining for up to 24 hr. CONCLUSIONS: The data presented in this manuscript is the first report of chemosensitization by in vivo pH modulation using CsCl in mice bearing prostate or any other tumor xenograft. © 2005 Wiley-Liss, Inc.
