Postoperative adjuvant chemotherapy of gastric cancer is efficient in clinic, but it is accompanied by some problems. The main problem is associated complications caused by chemotherapy, such as different degree adverse reactions of the digestive system, blood system, nervous system, chemotherapeutic drugs cause the complications occurrence of the hemocytopenia, haemoglobin reduction and thrombocytopenia resulted by myelosuppression, nausea and vomiting, diarrhea, hand foot syndrome and so on (9,10). The adverse reaction of chemotherapy was significantly reduced after the application of hyperbaric oxygen, for instance, myelosuppression, gastrointestinal reaction and hair loss in hyperbaric oxygen group improved markedly. The treatment of hyperbaric oxygen combined with chemotherapy has improved the efficacy of chemotherapy while reducing the adverse reaction of chemotherapy, which has been proved in experiments (11,12). However, the clinical application in postoperative gastric cancer has not been reported. There was a statistical difference between the experimental group and the control group in the hemocytopenia thrombocytopenia, nausea and vomiting, and peripheral nervous reaction (P<0.05), but there was no significant difference in hemoglobin reduction and diarrhea (P>0.05). Meanwhile, QLQ-C30 was performed to compare the life quality score in two groups. EORTCQLQ-C30 scale is used widely in the world, which can reflect the multidimensional structure of the life quality, it is applicable to determine the life quality of cancer patients in China (13). The results showed that the QLQ-C30 score of the experimental group was 42.32±16.20, the control group was 79.53±18.54, and the score of life quality in the experimental group was significantly lower than that in the control group, the QOL in the experimental group was significantly improved.

In this study, the application of hyperbaric oxygen combined with chemotherapy in the treatment of postoperative gastric cancer reduced the recent local recurrence rate and the side reaction, the safety, tolerance of chemotherapy and postoperative survival time of patients were markedly improved. The small sample is the main deficiency in the study, so it is not sufficient to evaluate the effect factors of postoperative adjuvant chemotherapy. Long-term survival was not assessed the follow-up time was not long enough. The long-term survival rate was not assessed as the follow-up time was not long enough. Further information was needed to improve the analysis of clinical efficacy and tolerance in postoperative chemotherapy patients and the specific mechanism in clinical application still needs to be further investigated.
