AIM: To study effects of the Fuzheng Huoxue anticancer prescription (Traditional Chinese Medicine) in treatment of gastric cancer.
METHODS: Sixty-nine patients with histologically confirmed mid- or late-stage gastric cancer were assigned to two groups. The treatment group included 35 cases (26 males and 9 females; 2 patients aged 33-40 years, 18 patients aged 41-60 years, and 15 patients aged 61-75 years; mean group age = 58.4 years). The control group included 34 cases (23 males and 11 females; 4 patients aged 33-40 years, 16 patients aged 41-60 years, and 14 patients aged 61-75 years; mean group age = 56.8 years. The two groups were not significantly different in sex, age, their clinical and pathological stages of disease or operation mode. The two groups of patients were given similar treatments; however, patients in the treatment group were given the Fuzheng Huoxue anticancer prescription. In animal studies, SGC-7901 gastric cancers cells were inoculated into the backs of 30 nude mice under sterile conditions. After inoculation, the nude mice were randomly allocated to a control group, a traditional Chinese medicine group, and a chemotherapy group (n = 10 mice per group). The total weight of the 10 mice in each group was similar. Each nude mouse in the control group received 0.5 mL of saline solution each day. Mice in the traditional Chinese medicine group received 0.5 mL of the Fuzheng Huoxue anticancer prescription (containing 1.5 g crude drug) each day, while mice in the chemotherapy group were intraperitoneally injected with 1 mg of 5-Fu once a week for 8 wk.
RESULTS: Prior to treatment, the mean OKT8 percentage among gastric patients in the treatment group was 45.94% ± 8.45%, the mean OKT4/OKT8 ratio was 0.89 ± 0.19, the mean AT-III concentration was 29.9 ± 7.9 mg/dL, the mean Fa value was 50.4% ± 24.4%, and the mean β-TG concentration was 91.0 ± 25.9 ng/dL. Prior to treatment, the mean percentage of OKT8 cells among patients in the control group was 49.21% ± 6.60%, the OKT4/OKT8 ratio was 0.94 ± 0.20, the AT-III concentration was 32.3 ± 7.2 mg/dL, the mean Fa value was 57.3% ± 24.6%, and the mean β-TG concentration was 87.5 ± 34.2 ng/dL. After treatment, the mean OKT8 percentage among patients in the treatment group was 33.52% ± 7.80%, the mean OKT4/OKT8 ratio was 1.47 ± 0.51, the mean AT-III concentration was 38.8 ± 5.5 mg/dL, the mean Fa value was 102.6% ± 31.6%, and the mean β-TG concentration was 62.3 ± 15.1 ng/dL. After treatment, the mean OKT8 percentage among patients in the control group was 42.22% ± 7.07%, the mean OKT4/OKT8 ratio was 1.12 ± 0.24, the mean AT-III concentration was 30.9 ± 8.0 mg/dL, the mean Fa value was 64.6% ± 26.9%, and the mean β-TG concentration was 67.0 ± 42.1 ng/dL. These data indicate that after treatment, the immunologic function of the T lymphocytes of gastric cancer patients in the treatment group was significantly improved (P < 0.01). Additionally, the hypercoagulability in the treatment group was also improved (P < 0.001), and the mean OKT4/OKT8 ratio, antithrombin III (AT-III) concentration, and fibrinolytic activity, etc. had all beome normalized. The one-year (86%), 3-year (69%), and 5-year (40%) survival rates in the treatment group were all higher than those in the control group (P < 0.05). The mean tumor weights in the control, traditional medicine, and chemotherapy groups were 0.895 ± 0.289 g, 0.433 ± 0.177 g, and 0.357 ± 0.142 g, respectively. The tumor-inhibition rates in the traditional Chinese medicine group and chemotherapeutic group (51.6% and 60.1%, respectively) were significantly better than that in the control group (P < 0.001). The mean tumor weight in the traditional Chinese medicine group (24.68 ± 1.93 g) was significantly higher than that in both the treatment group (22.96 ± 1.87 g) and control group (22.47 ± 2.18 g).
CONCLUSION: The Fuzheng Huoxue anticancer prescription can not only replenish vital functions (Zhengqi), correct a hypercoagulatory state, improve immunologic function, and extend patient survival times, but may also directly inhibit gastric tumor growth without producing toxic side effects.
