Model: AMS-H-03 Rated gas output (L) : 3L/min, concentration of hydrogen and the oxygen was 66.6% and 33.3%, respectively In this group, the patients will inhale hydrogen and oxygen with oxyhydrogen generator. The check indexes are questionnaire of sleep, diet and exercise, CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell).

In this group, the patients will inhale normal air with analogue machine. The check indexes are questionnaire of sleep, diet and exercise, CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell).

Rated gas output (L) : 3L/min, concentration of hydrogen and the oxygen was 66.6% and 33.3%, respectively. The patients inhale 3 hours each day through a cannula or mask, and persist for long term

It will be evaluated by the questionnaire of EORTC QLQ-C30. The scores of each index before and after treatment need to be analyzed by statistical methods to reach a conclusion, and P< 0.05 is considered to be statistically different

It will be evaluated by the blood test, including tumor marker alpha fetoprotein (AFP), lymphocyte subsets (T and NK cells) and circulating tumor cell (CTCs). The reference range of AFP is 0-40 IU/mL, higher than this range indicates tumor risk, and the higher the value is, the faster the tumor growth rate will be. The t-cell range of the lymphocyte subclass is 603-2990 cell/uL, and the NK cell range is 95-640 cell/uL, lower than the reference range indicates low immune function. The CTC reference range is 0-1, and higher than the reference range indicates tumor activity.
