[Influence of Chinese herbal medicine Feitai Capsule on completion or delay of chemotherapy in patients with stage IIIB/IV non-small-cell lung cancer: a randomized controlled trial].

BACKGROUND: Chemotherapy completion rate can reflect the tolerance and compliance of patients to chemotherapy. Poor tolerance may result in delay or suspension of the comprehensive treatment plan, thus affect the efficacy of cancer treatment. Evaluating methods to improve the completion rate of chemotherapy and reduce the occurrence of delayed chemotherapy has gained increasing attention and is the significant area of study in the field of cancer treatment. Studies have shown that Chinese medicine combined with chemotherapy could improve the quality of life in patients with stage IIIB/IV non-small-cell lung cancer (NSCLC). OBJECTIVE: To observe the effects of Feitai Capsule, a Chinese patent herbal drug, combined with chemotherapy in patients with stage IIIB/IV NSCLC. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: A total of 60 diagnosed stage IIIB/IV NSCLC patients from the Department of Oncology, Fuzhou General Hosipital of Najing Military Region were randomly divided into treatment group (30 cases) and control group (30 cases). Patients in the treatment group were treated with chemotherapy plus Feitai Capsule and patients in the control group only received chemotherapy. Both groups of patients were treated for 4 therapeutic cycles. MAIN OUTCOME MEASURES: The chemotherapy completion rate and the chemotherapy delay rate were observed in each cycle of treatment. The therapeutic efficacy was evaluated after 4 cycles. RESULTS: The chemotherapy completion rate was 96.42% in the treatment group, while that of the control group was 74.07%. The chemotherapy delay rate was 3.57% in the treatment group, while that of the control group was 14.8% (P=0.007 0). The disease control rate was 78.6% in the treatment group, while that of the control group was 59.3% (P=0.173 9). CONCLUSION: Feitai Capsule can increase the chemotherapy completion rate in patients with stage IIIB/IV NSCLC.

Effect of Feitai Capsule () on quality of life and progression-free survival of patients with unresectable non-small cell lung cancer.

OBJECTIVE: To examine the effect of a Chinese medicinal herbal formula (Feitai Capsule, ) on the quality of life (QOL) and progression-free survival (PFS) of patients with unresectable non-small cell lung cancer (NSCLC). METHODS: Sixty-two patients were randomly divided into the treatment group (31 cases) and the control group (31 cases). For the treatment group, 4 capsules (1.2 g/capsule) of Feitai Capsule were administered 3 times a day after meals for 3 weeks; then no drug was administered for 1 week. This schedule was continued for at least 3 more cycles (12 weeks totally). If there were no obvious toxic reactions, the treatment was extended. The patients were evaluated at least once every 8 weeks until progressive disease (PD). For the control group, the regular follow-up and evaluation were performed at least once every 8 weeks until PD. Clinical symptoms, objective response, physical constitution and energy, QOL, and PFS were evaluated regularly. Analysis of variance (ANOVA), a non-parametric test, and analysis of covariance were used to compare clinical features, amelioration of clinical symptoms, physical constitution and energy, and QOL. Kaplan-Meier analysis was used to compare the two-group PFS. RESULTS: Sixty patients finished the final evaluation, with 30 patients in each group. Baseline characters between groups were not significantly different (P>0.05). The control group had a 36.7% improvement in clinical symptoms, while the treatment group had a 73.3% improvement. This difference was statistically significant (Z= -2.632, P=0.008). The control group had a 26.7% improvement in the Karnofsky performance status (KPS), while the treatment group had a 53.4% improvement. This was also significantly different (Z=-2.182, P=0.029). A comparative analysis indicated a positive correlation (r=0.917, P<0.001). Compared with the control group, QOL in the treatment group was significantly improved, except in the social/family condition and doctor-patient relationship indicators. The PFS of the treatment group and control group were 6.23 months and 4.67 months, respectively (P=0.048). CONCLUSION: Feitai Capsule, a Chinese medicinal herbal treatment could improve the QOL and extend the PFS of the unresectable NSCLC patients.

[Effects of Feitai Capsule on quality of life in patients with advanced non-small-cell lung cancer: a randomized controlled trial].

BACKGROUND: Recently the maintenance therapy of non-small-cell lung cancer (NSCLC) patients who completed required treatment cycles has caused widespread interests in the medical field. Traditional Chinese medicine may be a useful complement in maintenance treatment of mid-to-late stage NSCLC. OBJECTIVE: To observe the effects of Feitai Capsule, a compound traditional Chinese herbal medicine for expelling blood stasis and phlegm, on the quality of life of the NSCLC patients as a maintenance treatment. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: A total of 62 mid-to-late stage NSCLC patients from Fuzhou General Hospital of Nanjing Military Region were included and randomly divided into treatment group (31 cases) and control group (31 cases). Patients in the treatment group were treated with Feitai Capsule, and patients in the control group did not accept any intervention. Regular observations and follow-up were performed for patients in the two groups. MAIN OUTCOME MEASURES: Analysis of variance, nonparametric test, and analysis of covariance were used to compare clinical features, amelioration of clinical symptoms, physical constitution and energy, and quality of life. RESULTS: There were two dropouts and 60 valid cases. The baseline characteristics of the two groups were similar. In the treatment group, symptom response and physical energy level were improved by 36.6% (Z=-2.632, P=0.008) and 26.7%(Z=-2.182, P=0.029), respectively. There was a positive correlation between these two factors (r=0.917, P<0.001). The patients in treatment group had a significantly improved quality of life after treatment. No serious adverse events were observed. CONCLUSION: Feitai Capsule as maintenance treatment can improve the quality of life of the patients with mild-to-late stage NSCLC.

Monitoring of immune responses to a herbal immuno-modulator in patients with advanced colorectal cancer.

Many herbal medicines are widely used as immuno-modulators in Asian countries. Ganoderma lucidum (Lingzhi) is one of the most commonly used herbs in Asia and preclinical studies have established that the polysaccharide fractions of G. lucidum have potent immuno-modulating effects. However, clinical evidence for this is scanty. The present open-labeled study aimed to evaluate the effects of G. lucidum polysaccharides on selected immune functions in patients with advanced colorectal cancer. Forty-seven patients were enrolled and treated with oral G. lucidum at 5.4 g/day for 12 weeks. Selected immune parameters were monitored using various immunological methods throughout the study. In 41 assessable cancer patients, treatment with G. lucidum tended to increase mitogenic reactivity to phytohemagglutinin, counts of CD3, CD4, CD8 and CD56 lymphocytes, plasma concentrations of interleukin (IL)-2, IL-6 and interferon (IFN)-gamma, and NK activity, whereas plasma concentrations of IL-1 and tumor necrosis factor (TNF)-alpha were decreased. For all of these parameters, no statistical significance was observed when a comparison was conducted between baseline and those values after a 12-week treatment with G. lucidum. The changes of IL-1 were correlated with those for IL-6, IFN-gamma, CD3, CD4, CD8 and NK activity (p<0.05) and IL-2 changes were correlated with those for IL-6, CD8 and NK activity. The results indicate that G. lucidum may have potential immuno-modulating effect in patients with advanced colorectal cancer. Further studies are needed to explore the benefits and safety of G. lucidum in cancer patients.

[Efficacy of Lentinan combined with chemotherapy in advanced non-small cell lung cancer].

BACKGROUND: Lentinus edodes polysaccharide (Lentinan) has attracted great attention from both pharmacologists and clinicians as a biological response modifier, and is widely used as an anti-tumor agent in both China and Japan. The aim of this study is to observe the efficacy of Lentinan combined with chemotherapy in stage III-IV non-small cell lung cancer (NSCLC). METHODS: Eighty-one patients with stage III-IV NSCLC were randomly divided into two groups: (1)Lentinan + chemotherapy group (group A, 42 cases); (2)Simple chemotherapy group (group B, 39 cases). The peripheral blood T lymphocyte subsets (CD3, CD4, CD4/CD8) and natural killer (NK) cell activity of patients in both groups were measured before and after treatment, while compared with healthy control (30 cases). The immune functions, the effect of treatment, quality of life, and adverse reactions were observed. RESULTS: After treatment the objective response rate (CR+PR) was 50% in group A, compared to 33% in group B (P < 0.05). The blood T cell levels(CD3, CD4, CD4/CD8) and NK cell activity in group A increased (P < 0.01), CD8 reduced (P < 0.05), but in group B the value had no obvious change (P > 0.05). Quality of life in group A was higher than that in group B (P < 0.01). The incidence of grade II-IV leukopenia, nausea and vomiting in group B was much higher than those in group A (P < 0.05). CONCLUSIONS: The therapeutic effect of Lentinan combined with chemotherapy is better than that of chemotherapy alone.

Clinical study on treatment of primary hepatocellular carcinoma by Shenqi mixture combined with microwave coagulation.

OBJECTIVE: To observe the short-term efficacy and safety of Shenqi mixture (SQM) combined with microwave coagulation in treating primary hepatocellular carcinoma (HCC). METHODS: Seventy-two patients with primary HCC of stage II-III, Karnofsky scoring > or = 50 scores and predicted survival period > or = 3 months were selected and randomly assigned into two groups, the treated group and the control group, 36 in each. Microwave therapy was applied to both groups by double leads, 60 W, 800 sec once a week for two weeks. To the treated group, SQM was given additionally through oral intake of 20 ml, three times a day for 1 month. The changes in tumor size, main symptoms, serum level of alpha-fetoprotein (AFP), immune function and adverse reaction were observed after treatment and the immune parameters of the patients were compared with 30 healthy persons in the normal control group. RESULTS: (1) In the SQM treated group, after treatment 3 patients got completely remitted (CR), 24 partial remitted (PR), 4 unchanged (NC) and 5 progressively deteriorated (PD), the effective rate being 75.00%; while in the control group, 1 got CR, 19 PR, 9 NC and 7 PD, the effective rate being 55.56%. Comparison of the effective rate between the two groups showed significant difference (P < 0.05). (2) AFP level decreased after treatment in both groups, but the decrement in the treated group was significantly higher than that in the control group (P < 0.01). (3) After treatment, in the treated group, CD3(+), CD4(+), CD4(+)/CD8(+) and NK activity were improved, Karnofsky scores increased and liver function bettered, with these improvements significantly superior to those in the control group (P < 0.01). (4) The improvement in symptoms such as hepatic region pain, fever, weakness, poor appetite and jaundice in the treated group after treatment was also superior to that in the control group (P < 0.01). (5) The 12-month, 18-month and 24-month survival rates were higher and the recurrence rate was lower in the treated group than those in the control group, showing significant difference (P < 0.05). CONCLUSION: Combined therapy with SQM and microwave coagulation could not only kill the tumor and residue tumor cells to prevent recurrence, but also enhance the cellular immunity of organism. It is one of the effective therapies for patients with middle-advanced hepatocarcinoma, who have lost the chance of surgical operation. It could improve clinical symptoms, elevate the quality of life, prolong the survival period of patients, but shows no evident adverse reaction.

Effects of water-soluble Ganoderma lucidum polysaccharides on the immune functions of patients with advanced lung cancer.

Preclinical studies have established that the polysaccharide fractions of Ganoderma lucidum have potential antitumor activity. Recent clinical studies have demonstrated that G. lucidum polysaccharides enhance host immune functions [e.g., enhanced natural killer (NK) cell activity] in patients with advanced solid tumors, although an objective response was not observed. This open-label study aimed to evaluate the effects of water-soluble G. lucidum polysaccharides (Ganopoly, Encore International Corp., Auckland, New Zealand) on immune functions in patients with advanced lung cancer. Thirty-six patients were enrolled and treated with 5.4 g/day Ganopoly for 12 weeks. In the 30 cancer patients who completed the trial, treatment with Ganopoly did not significantly alter the mean mitogenic reactivity to phytohemagglutinin, mean counts of CD3, CD4, CD8, and CD56, mean plasma concentrations of interleukin (IL)-2, IL-6, and interferon (IFN)-gamma, or NK activity in the patients, but the results were significantly variable. However, some cancer patients demonstrated markedly modulated immune functions. The changes in IL-1 were correlated with those for IL-6, IFN-gamma, CD3, CD8, and NK activity (P < .05), and IL-2 changes were correlated with those for IL-6, CD8, and NK activity. The results suggest that subgroups of cancer patients might be responsive to Ganopoly in combination with chemotherapy/radiotherapy. Further studies are needed to explore the efficacy and safety of Ganopoly used alone or in combination with chemotherapy/radiotherapy in lung cancer patients.

A randomized, double-blind and placebo-controlled study of a Ganoderma lucidum polysaccharide extract in neurasthenia.

Ganoderma lucidum has been widely used to treat various diseases, including cancer, diabetes, and neurasthenia in many Asian countries. This randomized, double-blind, placebo-controlled parallel study aimed to investigate the efficacy and safety of a polysaccharide extract of G. lucidum (Ganopoly) in Chinese patients with neurasthenia. One hundred thirty-two patients with neurasthenia according to the diagnosis criteria of the 10th International Classification of Diseases were included in this study. Written consents were obtained from the patients, and the study was conducted in accordance with Good Clinical Practice guidelines. Patients were randomized to receive Ganopoly or placebo orally at 1,800 mg three times a day for 8 weeks. Efficacy assessments comprised the Clinical Global Impression (CGI) improvement of severity scale and the Visual Analogues Scales for the sense of fatigue and well-being. In 123 assessable patients in two treatment groups at the end of the study, Ganopoly treatment for 8 weeks resulted in significantly lower scores after 8 weeks in the CGI severity score and sense of fatigue, with a respective reduction of 15.5% and 28.3% from baseline, whereas the reductions in the placebo group were 4.9% and 20.1%, respectively. The score at day 56 in the sense of well-being increased from baseline to 38.7% in the Ganopoly group compared with 29.7% in the placebo group. The distribution of the five possible outcomes from very much improved to minimally worse was significantly different (X (2) = 10.55; df = 4; P = .0322) after treatment with Ganopoly or placebo. There was a percentage of 51.6% (32 of 62) in the Ganopoly group rated as more than minimally improved compared with 24.6% (15 of 61) in the placebo group (X (2) = 9.51; df = 1; P = .002). Ganopoly was well tolerated in the study patients. These findings indicated that Ganopoly was significantly superior to placebo with respect to the clinical improvement of symptoms in neurasthenia.

[Relationship between sCD44v6 expression and TCM differentiation type of gastric carcinoma patients and influence of weitai capsule on the expression].

OBJECTIVE: To explore the relationship of TCM type with serum level of soluble CD44v6 (sCD44v6) and different histologic parameters in gastric carcinoma patients and to observe the influence of Weitai capsule (WTC) on the sCD44v6 expression. METHODS: TCM typing and sCD44v6 expression were determined in all the enrolled patients (30 in the control and 32 in the trial group) before operation, and 3-4 courses of chemotherapy was applied to them from 3-4 weeks after operation. To the patients of trial group, oral administration of WTC was given additionally with 4 capsules, 3 times a day for consecutive 3 months. RESULTS: sCD44v6 was significantly positive correlated with the degree of cancer cell differentiation, infiltration and lymph node metastasis; (2) Level of sCD44v6 was the highest in patients of blood stasis type, as compared with that in the patients of Pi-deficiency type or of damp-heat type, the difference was significant; (3) After ending treatment, level of sCD44v6 in the trial group was significantly lower than that in the control group. CONCLUSION: (1) Serum level of sCD44v6 could be taken as the criterion for evaluating the development and prognosis of gastric cancer, as well as the therapeutic target for anti-metastasis treatment; (2) Serum level of sCD44v6 is related to some extent with TCM type of blood stasis and Pi-deficiency; (3) WTC combined with chemotherapy could further inhibit the expression of serum sCD44v6 in gastric carcinoma patients.

[Effects of shouwu-huanjing recipe on human sperm motility and fertility in vitro].

OBJECTIVE: To observe the effect of Shouwu-Huanjing Recipe(SWHJR) medicated serum on human sperm motility and fertility in vitro. METHODS: Human sperm was co-cultured with SWHJR medicated serum in vitro. Human sperm motility was evaluated by computer-assisted semen analysis(CASA). The acrosome reaction and the capability of penetrating zona-free hamster eggs were also observed. RESULTS: The co-cultured SWHJR medicated serum significantly increased the sperm motion velocity(VAP, VCL, VSL) (P < 0.01), the amplitude of lateral head movement (ALH) and the beat frequency of flagellum(BCF), the density of progressive motility sperms (P < 0.05), the acrosome reaction rate(P < 0.001), the fertilization rate(FR) and the fertilization index (FI) in sperm penetration assay(SPA) test (P < 0.01). The stimulation of SWHJR medicated serum occurred in dose-dependent manner. CONCLUSION: SWHJR can improve human sperm motility and fertility.

Effects of ganopoly (a Ganoderma lucidum polysaccharide extract) on the immune functions in advanced-stage cancer patients.

Preclinical studies have established that the Ganoderma lucidum polysaccharide (GLPS) fractions have potent anti-tumor activity, which has been associated with the immuno-stimulating effects of GLPS. However, it is unclear whether GLPS has immuno-modulating effects in humans in vivo. This study aimed to investigate the effects of Ganopoly, the polysaccharides fractions extracted from G. lucidum, on the immune function of advanced-stage cancer patients. Thirty-four advance-stage cancer patients were entered onto this study, and treated with 1800 mg Ganopoly, three times daily orally before meals for 12 weeks. Immune parameters (cytokines, T cell subsets, mitotic response to phytohemagglutinin (PHA) and natural killer activity) were compared between baseline and after 12-week treatment. Thirty patients are assessable for their immune functions. Treatment of Ganopoly for 12 weeks resulted in a significant (P < 0.05) increase in the mean plasma concentrations of interleukin (IL-2), IL-6, and interferon (IFN)-gamma, whereas the levels of IL-1 and tumor necrosis factor (TNF-alpha) were significantly (P < 0.05) decreased. A marked variability among patients with advanced-stage cancer was observed in the numbers of each lymphocyte subset at baseline. The mean absolute number of CD56+ cells was significantly (P < 0.05) increased after 12-week treatment of Ganopoly, whereas the numbers of CD3+, CD4+, and CD8+ were just marginally increased compared to baseline levels, with the CD4:CD8 T cell ratios unchanged. PHA responses after 12-week treatment with Ganopoly were enhanced in most patients, when compared to pretreatment baselines (P < 0.05). In addition, Ganopoly treatment resulted in a significant increase (P < 0.05) in the mean NK activity compared to baselines (34.5 +/- 11.8% vs 26.6 +/- 8.3%). The present study indicates that Ganopoly enhanced the immune responses in patients with advanced-stage cancer. Clinical evaluations of response and toxicity are ongoing.
