Abstract

This study was conducted to evaluate the efficacy and safety of vanadium water (VW) on cancer-related fatigue of non-advanced cancer patients. For the experimental group administration, participants consumed three 500 mL/bottle bottles of Jeju Island's VW, which contained 15~20 ppb of vanadium, three times a day (morning, afternoon, evening) for 4 weeks (28 days) without any additional treatments for fatigue improvement. The control group participants consumed three 500 mL/bottle bottles of ordinary water (0 ppb of vanadium) three times a day for the same period of time without any additional treatments for fatigue improvement. After 4 weeks of VW consumption, total score of Revised Piper Fatigue Scale (RPFS) was reduced 30% compared to the basal score after Fisher's Exact Test which resulted in a statistical borderline significance (p=0.0799) and result of t-test of comparison between two groups' RPFS total score and fatigue cognitive/mood changes resulted in a statistical significance (p=0.0112). In detail, only 36.4% of control group (N=11) showed improvement while 77.8% of treatment group (N=9) showed fatigue improvement. No other lab measures, including thyroid hormone level indicated any significant differences between two groups. In conclusion, daily consumption of 1.5 L of vanadium water for 4 weeks showed improvement of non-advanced cancer patients' fatigue.

본 연구는 1일 1.5 L씩 4주간의 바나듐수 음용이 비진행성 암환자의 피로감 개선에 긍정적인 효과를 미치는 지 확인하기 위하여 수행되었다. 본 연구 결과 4주간의 바나듐수 음용은 비진행성 암환자의 피로감 개선을 위해 통계적으로 경계선상의 유의성을 보였으므로 향후에는 탐색형 연구로부터 확증형 연구를 통하여 피험자 수가 증가할 경우 통계학적으로 유의성을 보일 것이라고 예상되므로 근거 확보를 위한 진일보한 연구가 이루어져야 할 것이다. 즉 1일 1.5 L씩 4주간의 바나듐수 음용은 비진행성 암환자의 피로감 개선에 대해 유의수준 10%에서 통계적으로 유의한 차이가 나타났다. 이는 바나듐수가 암 환자의 피로에 도움이 되고 또한 참여자 수가 늘어날 경우 통계학적으로 유의성을 보일 것이라는 최소한의 근거를 보여주는 것이다. 향후에는 피험자수의 증가를 비롯하여 성별, 암종별 피험자수를 매치하고 피로감 개선을 포함한 기타 추가 기능에 대한 연구 수행을 기대할 수 있겠다.
