[Effect of Fuzheng Kang'ai Recipe Combined Gefitinib on Lung Cancer A549 Cells and Its Mecha- nism Research].

Objective To observe the effect of Fuzheng Kang'ai Recipe (FKR) combined ge- fitinib on the proliferation and apoptosis of lung cancer A549 cells , and to study its potential synergistic mechanish with gefitinib. Methods The effects of FKR (0. 211, 0. 316, 0. 474, 0. 711, 1. 067, 1. 600, 2. 400, 3. 600 mg/mL) combined gefitinib (3. 95, 5. 92, 8. 18, 13. 33, 20. 00, 30. 00, 45. 00, 67. 50 µmol/ L) on the proliferation of A549 cells were detected by MTT assay. The apoptosis of A549 cells in the control group (complete culture medium) , FKR (1. 6 mg/mL) , gefitinib (45 µmol/L) , and FKR plus gefitinib (1. 6 mg/mL +45 µmol/L) were detected by flow cytometry (FCM). Their expressions of epidermal growth factor receptor (EGFR) , phosphorylating epidermal growth factor receptor ( p-EGFR) , enhancer of zeste homolog 2 (EZH2), peroxisome proliferator-activated receptor-γ ( PPAR-γ) , and P53 protein in A549 cells were detected by Western blot. Results Both FKR and gefitinib could inhibit the proliferation of A549 cells. The apoptotic rate was 12. 6% ±4. 5% in the FKR combined gefitinib group, obviously higher than that of the FKR group (4. 6% ± 0. 7%) and the gefitinib group (7. 8% ± 2. 7%) , showing statistical difference (P <0. 05). Compared with the control group, the expressions of p-EGFR and EZH2 were sig- nificantly down-regulated (P <0. 05) , the expressions of PPAR-γ and P53 protein were up-regulated in the FKR combined gefitinib group (P <0. 05); the expression of EZH2 was down-regulated in the gefitinib group and the FKR group (P <0. 05) ; the expression of PPAR-y was up-regulated in the FKR group (P < 0. 05). Compared with the gefitinib group, the expression of p-EGFR was down-regulated, and the expression of PPAR-γ was up-regulated in the FKR combined gefitinib group (both P <0. 05). Compared with the FKR group, the expression of p-EGFR was down-regulated in the FKR combined gefitinib group (P < 0. 05). Conclusions Combination of FKR and gefitinib could significantly inhibit the proliferation and growth of A549 cells,and induce cell apoptosis. Its potential synergistic mechanism of anti-tumor activities might be associated with down-regulating mRNA expressions of p-EGFR and EZH2, and up-regulating protein expressions of PPAR-y and P53.

[Combination of Jianpi Liqi Yiliu Formula with Cytokine-induced Killer Cell Treatment for Advanced Hepatocellular Carcinoma].

OBJECTIVE: To evaluate the clinical efficacy of Jianpi Liqi Yiliu Formula (JLYF) combined with cytokine-induced killer (CIK) cells for treating patients with advanced hepatocellular carcinoma (HCC). METHODS: Between January 2011 and January 2014, 60 advanced HCC patients were enrolled in this study, who were assigned to the treatment group and the control group according to their willingness for taking JLYF, 30 cases in each group. All patients received CIK cell treatment: 1 x 109-3 x 109 each time, by intravenous dripping from the 1st day to the 3rd day, once per day. Besides, patients in the treatment group took JLYF decoction, while those in the control group took Chinese medical decoction by syndrome typing. All patients received treatment of at least two cycles. The time to progression (TTP) , overall survival (OS), disease control rate (DCR), performance status scale (PS), Child-Pugh scale, and adverse reactions were observed, and subgroup analyzed. RESULTS: To May 31, 2014, all patients reached the clinical endpoint. TTP was 3.5 months (95% Cl: 3.30-4.10) in the treatment group, better than that (2.5 months, 95% CI: 2.32-2.68) of the control group (P < 0.05). DCR was 36.7% in the treatment group and 30.0% in the control group (P > 0.05). OS was 5.2 months (95% CI: 4.53-5.87) in the treatment group and 4.6 months (95% CI: 4.06-5.14) in the control group (P > 0.05). The PS scale was 1.60 ± 0.10 after treatment, lower than that (1.80 ± 0.09) before treatment in the treatment group (P < 0.05). When the PS scale was 0-2 or Child-Pugh scale was class A, TTP was longer in the treatment group than in the control group (P < 0.05). No adverse reaction occurred in the two groups during the treatment course. CONCLUSIONS: The combination of JLYF with ClK cell treatment could prolong advanced HCC patients' TTP, improve PS scale, as compared with syndrome typed Chinese medical decoction treatment group. Besides, when the PS scale was 0-2 or Child-Pugh scale was class A, it was a better treatment program for advanced HCC patients.

[Treating primary liver cancer patients by Pi-strengthening and Qi-regulating method: univariate and multivariate analyses of their prognoses].

OBJECTIVE: To evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program. METHODS: Clinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out. RESULTS: The 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05). CONCLUSION: The prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.

[The distribution of Chinese medicine syndrome types in primary liver cancer and their differences of the survival time: a clinical study].

OBJECTIVE: To explore the distribution of Chinese medicine (CM) syndrome types in primary liver cancer (PLC) and their differences of the survival time. METHODS: From May 2007 to March 2009, recruited were 151 PLC inpatients at Department of Tumor, Guangdong Provincial Hospital of Traditional Chinese Medicine. Their survival time were statistically calculated. Patients' average survival time and median survival time were calculated using Kaplan-Meier method. The Log-rank test was used to analyze their differences of survival time among different CM syndrome types. RESULTS: The proportion of CM syndrome types in PLC patients were ranked from high to low as follows: mutual accumulation of dampness and blood stasis syndrome [MADBSS, 43.0% (65/151)], Gan-stagnation Pi-deficiency syndrome [GSPDS, 34.4% (52/151)], qi stagnation blood stasis syndrome [QSBSS, 9.3% (14/151)], retention of damp-heat syndrome [RDHS, 8.6%(13/151)], and Gan-Shen yin deficiency syndrome [GSYDS, 4.6% (7/ 151)]. The median survival time of different CM syndrome types were ranked from longer to shorter as follows: GSPDS (14.77 months), QSBSS (6.13 months), RDHS (5.27 months), MADBSS (4.78 months), and GSYDS (0.80 months). The mean survival times were ranked from longer to shorter as follows: GSPDS (12.40 months), QSBSS (8.84 months), MADBSS (6.99 months), RDHS (7.08 months), and GSYDS (0.72 months). There was statistical difference in the difference of the survival time among different CM syndrome types (P < 0.05). CONCLUSIONS: GSPDS and MADBSS were the most common CM syndrome types in PLC patients. There was difference in the survival time between GSPDS and MADBSS/between RDHS and GSYDS. There was difference in the survival time between MADBSS and GSYDS. Patients of GSPDS might get the best prognosis, while patients of GSYDS might get the poorest prognosis.

[Effect of shenfu injection for attenuating the toxicity of cisplatin-based regimens in treating non-small cell lung cancer].

OBJECTIVE: To observe the effect of Shenfu Injection (SFI) for attenuating the toxicity of chemotherapy in treating non-small-cell lung cancer (NSCLC), by the regimens of combined Cisplatin (DDP) with new chemotherapeutic agents, Taxol (TXT), Vinorelbine (NVB) and Gemcitabine (GEM), respectively. METHODS: One hundred and thirty-three patients with NSCLC, who were scheduled to be treated by at least 2 cycles of chemotherapy, with regimen TP (45 cases), NP (42 cases) and GP (46 cases), were enrolled. They were randomized into 2 groups: 67 cases in the SFI pre-treated group and 66 cases in the SFI post-treated group, on them SFI was administered for 10 successive days on the 1st, 2nd, 3rd day of the 1st and the 2nd cycle, respectively. The effects of SFI on toxicity of the three regimens were observed through a self-controlled crossover design. RESULTS: The hemato-toxicity (the toxicity on leukocyte, neutrophil, hemoglobin and platelet) and the digestive toxicity (represented as vomiting, constipation or diarrhea) of chemotherapy revealed in the treated stage (the cycle treated with SFI) were all less than those in the control stage (the cycle untreated with SFI), no matter when SFI was applied, all showed statistical significance (P < 0.05 or P < 0.01). Besides, SFI showed a better toxicity attenuating effect on patients of qi-deficiency and phlegm-dampness type (P < 0.01). CONCLUSION: SFI can relieve the hemato-toxicity and the digestive toxicity of chemotherapy by regimen of combining DDP with TXT, NVB or GEM, and the effect is more significant on patients of qi-deficiency and phlegm-dampness type.

Gefitinib plus Fuzheng Kang'ai Formula () in Patients with Advanced Non-Small Cell Lung Cancer with Epidermal Growth Factor Receptor Mutation: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect of Fuzheng Kang'ai Formula (, FZKA) plus gefitinib in patients with advanced non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutations. METHODS: A randomized controlled trial was conducted from 2009 to 2012 in South China. Seventy chemotherapynaive patients diagnosed with stage IIIB/IV non-small cell lung cancer with EGFR mutations were randomly assigned to GF group [gefitinib (250 mg/day orally) plus FZKA (250 mL, twice per day, orally); 35 cases] or G group (gefitinib 250 mg/day orally; 35 cases) according to the random number table and received treatment until progression of the disease, or development of unacceptable toxicities. The primary endpoint [progression-free survival (PFS)] and secondary endpoints [median survival time (MST), objective response rate (ORR), disease control rate (DCR) and safety] were observed. RESULTS: No patient was excluded after randomization. GF group had significantly longer PFS and MST compared with the G group, with median PFS of 12.5 months (95% CI 3.30-21.69) vs. 8.4 months (95% CI 6.30-10.50; log-rank P<0.01), MST of 21.5 months (95% CI 17.28-25.73) vs. 18.3 months (95% CI 17.97-18.63; log-rank P<0.01). ORR and DCR in GF group and G group were 65.7% vs. 57.1%, 94.3% vs. 80.0%, respectively (P>0.05). The most common toxic effects in the GF group and G group were rash or acne (42.8% vs. 57.1%, P>0.05), diarrhea (11.5% vs. 31.4%, P<0.05), and stomatitis (2.9% vs. 8.7%, P>0.05). CONCLUSION: Patients with advanced non-small cell lung cancer selected by EGFR mutations have longer PFS, MST with less toxicity treated with gefitinib plus FZKA than gefitinib alone.

Improvement of quality of life with Shenfu injection in non small cell lung cancer patients treated with gemcitabine plus cisplatin regimen.

OBJECTIVE: To observe the effect of Shenfu injection (SFI) in treating non small cell lung cancer (NSCLC) patients on quality of life with gemcitabine (GEM) plus cisplatin (GP) regimen. METHODS: Thirty-four patients were ready to receive GP regimen chemotherapy for treating NSCLC disease, according to lot-drawing, they were divided into SFI pre-treatment group (18 cases) and SFI post-treatment group (16 cases). SFI pre-treatment group: During the first treatment course, chemotherapy was begun with SFI 60 ml, intravenous dripping on the 3rd day, once daily, consecutively for 10 days; on the 1st day, GP regimen (GEM 1250 mg/m(2), intravenous dripping, on the 1st and 8th day; cisplatin 70 mg/m(2) on the 2nd day; 21 days as one cycle) was carried out; in the second treatment course GP regimen was merely given to serve as the self-control. SFI post-treatment group: the medicament sequence order was reversed from that of pre-treatment group. Using dual international quality of life (QOL) scores, the effect of SFI on the patients' QOL was observed through randomized self pre- and post-crossover control. RESULTS: The QOL in the 34 patients after being treated by SFI in combination with GP chemotherapy regimen in one group, and GP chemotherapy regimen alone in the other, was improved in different degrees, with significant difference (P < 0.01); comparison of SFI combined with GP chemotherapy regimen with GP chemotherapy alone showed that QOL in patients was significantly different (P < 0.01). CONCLUSION: SFI could improve QOL in patients with NSCLC who were treated with GP regimen.

Fuzheng Kang'ai decoction combined with gefitinib in advanced non-small cell lung cancer patients with epidermal growth factor receptor mutations: study protocol for a randomized controlled trial.

BACKGROUND: Patients with advanced non-small cell lung cancer (NSCLC) harboring mutations of the epidermal growth factor receptor (EGFR) gene respond well to the EGFR tyrosine kinase inhibitor (TKI) gefitinib. Chinese herbal medicine (CHM) has been used as a complementary therapy for cancer for decades in China. CHM was proved to be effective in improving the quality of life (QOL) and reducing the toxicity associated with chemotherapy in patients with NSCLC. The purpose of the present trial is to determine whether CHM (Fuzheng Kang'ai decoction (FZKA), a CHM formula) combined with gefitinib results in longer progression-free survival with less toxicity than gefitinib alone. METHODS/DESIGN: This is a randomized, placebo-controlled, double-blind trial. This trial is designed to determine if CHM (FZKA) combined with gefitinib results in longer progression-free survival with less toxicity than gefitinib alone. A total of 70 NSCLC patients with EGFR mutations will be randomly assigned to treatment group (gefitinib plus FZKA granules) or control group (gefitinib plus placebo). The primary endpoint is progression-free survival. Secondary endpoints are: (1) overall survival; (2) disease control rate; (3) QOL, measured with the questionnaire of Functional Assessment of Cancer Therapy-lung (FACT-L 4.0) and Lung Cancer Symptom Scale and (4) safety. DISCUSSION: In previous clinical practice, we found that CHM (FZKA) could improve the therapeutic efficacy of gefitinib. This study will provide objective evidence to evaluate the efficiency of CHM combined with gefitinib in NSCLC patients with EGFR mutations, and may provide a novel regimen for patients with NSCLC.

Effect of gefitinib plus Chinese herbal medicine (CHM) in patients with advanced non-small-cell lung cancer: a retrospective case-control study.

BACKGROUND: Some patients with non-small-cell lung cancer (NSCLC) respond well to the EGFR tyrosine kinase inhibitor gefitinib. Chinese herbal medicine (CHM) was effective in improving the quality of life and prolonging overall survival in patient with NSCLC. We aim to determine whether gefitinib plus CHM could prolong the progression-free survival (PFS) or median survival time (MST) in patients with NSCLC than gefitinib alone. METHODS: We retrospectively analyzed 159 non-small-cell lung cancer patients with the method of retrospective case-control study, matching factors included gender, age categories (30-39,40-49,50-59,60-69,70-79), pathological stage (IIIB or IV), smoking status (never: <100 lifetime cigarettes, or ever: ≥100 lifetime cigarettes), pathology, and performance status. Among the 159 patients, 100 patients treated with gefitinib (250mg/day orally) plus CHM ("Fuzheng Kang'ai" decoction, a Chinese herbal medicine, 250ml/bid/day orally), 59 patients treated with gefitinib (250mg/day orally) only. PFS and MST were analyzed for the whole population. RESULTS: 58 pairs were matched successfully. 1 patient (treated with gefitinib) with the age of 27 years failed to be matched. Progression-free survival was significantly longer in patients treated with gefitinib plus CHM than with gefitinib: median PFS was 13.1 months (95% CI 6.50-19.70) with gefitinib plus CHM versus 11.43 months (95% CI 7.95-14.91) with gefitinib (log-rank P=0.013). Median overall survival was longer with gefitinib plus CHM than with gefitinib: median MST was 22.83 months (95% CI 17.51-28.16) with gefitinib plus CHM versus 18.7 months (95% CI 16.83-20.57) with gefitinib (log-rank P=0.049). The most common adverse event was rash, the incidence in the gefitinib plus CHM group was 41.38% while in the gefitinib group was 24.14% (P=0.048). CONCLUSIONS: This case-control analysis suggested that treatment with gefitinib plus CHM prolonged PFS and MST compared with gefitinib in patients with NSCLC, and it is worthy of further study.

[Influence of Shenfu Injection on the quality of life of lung cancer patients receiving chemotherapy].

OBJECTIVE: To evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy. METHODS: A total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments. RESULTS: Both of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy. CONCLUSION: SHF can improve the quality of life in NSCLC patients receiving chemotherapies.

Treatment of advanced non-small cell lung cancer with extracorporeal high frequency thermotherapy combined with Chinese medicine.

OBJECTIVE: To observe the clinical efficacy and benefit response of extracorporeal high frequency thermotherapy (EHFT) combined with Chinese medicine (CM) in the treatment of patients with advanced nonsmall cell lung cancer. METHODS: The study adopted a prospective, small sample and randomized controlled method, and the advanced non-small cell lung cancer patients were assigned to two groups according to the table of random digits, one having the treatment of EHFT combined with CM (the treatment group), the other only with CM (the control group). The patients in the treatment group were treated with EHFT one hour once per day, together with CM differentiation decoction, 250 mL orally taken, twice daily for 14 days as one cycle, and 3-4 cycles was performed. The patients in the control group were treated only with CM differentiation decoction using the same dose as the treatment group. The efficacies were evaluated after three to four cycles of treatment. Primary endpoints were disease control rate (DCR) and time to progression (TTP). Secondary endpoints were overall survival time and 1-year survival rate. RESULTS: Sixty-six patients accomplished the study. After the patients underwent different treatments, none of the patients got a complete response or partial response in both groups. In the treatment group, DCR was 72.2%, and 10 had progression of disease (28.8%), while the DCR of the control group was 63.3%, and 11 had progression of disease (36.7%); there was a significant statistical difference (P <0.05), suggesting that the combined regimen had superiority on the DCR. As for long-term efficacy, the median survival time (MST) of the treatment group was 7.5 months, TTP was 5.5 months, and 1-year survival rate was 21.4 %; in the control group, the results were 6.8 months, 4.5 months and 16.6% respectively. There was significant statistical difference on TTP (P <0.05), but no difference on MST or 1-year survival rate. CONCLUSION: EHFT combined with CM differentiation has better tolerance and short-term efficacy in the treatment of patients with advanced NSCLC.
