Although advances in cancer therapies continue to develop, the shortness of the survival of lung cancer patients is still disappointing. Therefore, finding new adjuvant strategies is within the focus of cancer cure. Based on observations that deuterium depletion inhibits the growth of cancer cell lines and suppresses certain proto-oncogenes, we have conducted a clinical study in 129 patients with small cell and nonsmall cell lung cancers who consumed deuterium-depleted drinking water (DDW) as a nontoxic agent in addition to conventional chemotherapy and radiotherapy. Median survival time (MST) was 25.9 mo in males and 74.1 mo in female patients; the difference between genders was statistically significant (p < 0.05). Median survival of subjects with brain metastasis was 27.1 mo. Cumulative 5-yr survival probabilities were 19%, 52%, and 33% in males, females, and all patients with brain metastasis, respectively. Gene expression analysis in mouse lung indicated that DDW attenuates 7,12-dimethylbenz(a)anthracene (DMBA)-induced expression of Bcl2, Kras, and Myc in females. In conclusion, DDW counteracts the DMBA-induced overexpression of Bcl2, Kras and Myc genes in mouse lung, and it may extend survival of lung cancer patients as a nontoxic anticancer dietary supplement, especially for women with tumors overexpressing cancer-related genes, because MST of DDW-consuming group was 2–4 times longer than it is generally observed in lung cancer patients.
Deuterium-depleted water (DDW) is a new promising agent in cancer therapy. The efficiency of the method is based on the discovery, that cancer cells are extremely sensitive to depletion of deuterium (D) and might cause necrosis of the tumour. The purpose of this study was to show the efficacy of D-depletion in prostate cancer (PC) patients. In the double blind, four-month-long, randomized Phase II clinical trial the daily water intake was replaced with DDW in 22 PC patients. Other 22 PC patients took normal water while both groups received the same forms of conventional treatment. In the retrospective study, 91 DDW-treated PC patients were evaluated and median survival time (MST) in the subgroups was calculated. The time course of changes in DDW dose and PSA is presented in two cases. In the prospective trial seven patients in the treated group and one patient in the placebo group achieved partial response (p = 0.046). In the treated group, the net decrease in the prostate volume was three times higher (160.3 cm<sup>3</sup> vs. 54.0 cm<sup>3</sup>; p = 0.0019), urination complaints ceased at a higher rate (8 vs. 0 patients, p = 0.0041), and the one-year survival rate was also higher (2 vs. 9 deaths; p = 0.034). The 91 retrospectively evaluated patients achieved an MST of 11.02 years, despite the fact that 46 of them suffered from distant metastasis. In the two monitored patients, drop of PSA level correlated with the DDW intake. In summary, D-depletion prolonged MST in patients with PC. The method proved to be safe thus its integration in the PC cure as an adjuvant or complementary therapy would be considered
172metastasis from lung cancer.3 A considerably longer survival time was achieved only by patients with limited symptoms of the disease who were newly diagnosed thoracic stage I patients bearing a solitary brain metastasis. This subgroup of patients underwent successful brain surgery or stereotactic radiosurgery followed by WBI and achieved an MST of 25.6 months, whereas in patients with a locally advanced primary disease an MST of 9.9 months was achieved. 4 In a trial on stereotactic radiosurgery involving consecutive patients, including those suffering from advanced primary lung cancer and/or multiple brain and/or other distant metastases, the overall MST remained 7.0 months. 5 In a study on recurrent small cell lung carcinoma (SCLC) with brain metastases 6 MST was prolonged by as much as 18 months using radiosurgery. The administration of gefinitib, a tyrosine kinase inhibitor, led to the regression of brain metastases and resulted in an MST of L ung cancer is the leading cause of cancer-related death in men and women. A high percentage of lung cancer patients develop brain metastases resulting in poor prognosis. For a solitary brain metastasis surgical resection, and in the event of multiple metastases, whole brain irradiation (WBI) is considered standard treatment. In addition, aggressive management approaches, including surgical resection with or without WBI or nonsurgical approaches using stereotactic radiosurgery on its own or together with WBI, are standard treatments. Hypotheses. Because of the number of sufferers and high mortality rate, the standard care and new therapeutic options in the treatment of brain metastasis from lung cancer are the subject of intense research. A new concept based on the different chemical and physical behavior of protium and deuterium affecting cell signaling and tumor growth has been introduced in the treatment of cancer patients. The aim of this study was to investigate the impact of deuterium depleted water (DDW) consumption in addition to conventional forms of therapy on the survival of lung cancer patients with brain metastasis. Study design. A series of 4 case histories was retrospectively evaluated. The patients were diagnosed with brain metastasis deriving from a primary lung tumor and started consuming DDW at the time of or after the diagnosis of the brain metastasis, which was inoperable or the surgical intervention did not result in complete regression. The primary objective was survival. Methods. The daily water intake of the patients was replaced with DDW, which complemented the conventional forms of treatment. Patients were consuming DDW for at least 3 months. The treatment was continued with DDW of 10 to 15 to 20 ppm lower deuterium (D) content every 1 to 2 months and thus a gradual decrease was maintained in the D-concentration in the patient's body. Results. DDW consumption integrated into conventional treatments resulted in a survival time of 26.6, 54.6, 21.9, and 33.4 months in the 4 patients, respectively. The brain metastasis of 2 patients showed compl...
Work with sub-natural levels of deuterium (D) in animals has demonstrated an anti-cancer effect of low D-concentration in water. Our objective was to investigate whether deuterium-depleted water (DDW) can overturn reverse manganese (Mn)-induced reduction in life span, using the Caenorhabditis elegans (C. elegans) as a model system. DDW per se had no effect on worm’s life span 48 h after treatment; however, it reversed the Mn-induced decrease in C. elegans life span. Mn reduced DAF-16 levels, a transcription factor strongly associated with life-span regulation. Low D-concentration (90 ppm) restored the Mn-induced changes in DAF-16 to levels indistinguishable from controls, suggesting DDW can regulate the DAF-16 pathway. We further show that insulin-like receptor DAF-2 levels were unaltered by Mn exposure, tAKT levels increased, whilst superoxide dismutase (SOD-3) levels were decreased by Mn. DDW (90 ppm) restored the levels of tAKT and superoxide dismutase (SOD) to control values without changing DAF-2 levels. Treatment of Mn exposed worms with DDW (90 ppm) restored life-span, DAF-16 and SOD-3 levels to control levels, strongly suggesting that low D concentrations can protect against Mn toxic effects.
