In stage IV pulmonary adenocarcinoma patients, treatment with Traditional Chinese Medicine alone gives prognostically superior results to treatment with Platinum-Based Chemotherapy alone.

BACKGROUND: About 30% of pulmonary stage IV adenocarcinomas die within 3 months of diagnosis. Western medical treatments with Platinum-Based Chemotherapy=PBC and tyrosine-kinase inhibitors Targeted Therapy=TT can improve prognosis. In China, Traditional Chinese Medicine herbal treatments (TCM) are often used in addition to PBC and TT. A considerable number of patients refuse Western medical treatments and use TCM alone. However, the survival impact of the latter is unknown. HYPOTHESES TESTED: Treatment with TCM alone is prognostically superior to PBC alone. Addition of PBC or TT or both TT to TCM improves survival. METHODS: In this prospective observational, non-interventional study of 1017 consecutive first-onset stage IV NSCLC patients with up to 10 years follow-up, 261 who Died of Disease (DOD) within 3 months were omitted, as they never got the optimal Western medical therapies. All 218 non-adenocarcinomas were also omitted, leaving 538 stage IV adenocarcinomas treated by TCM alone (n = 29), PBC alone (N = 19) and TCM and other Western medical combinations (299 TCM and PBC, 50 TCM and TT, 141 TCM and PBC and TT) with 3 - 120 months follow-up. Survivals were compared using Alive with Disease (AWD) and DOD as endpoints. RESULTS: The patients treated only with TCM had 7 months better median survival than those that received PBC alone (17 and 10 months). The patients that received TCM and PBC had a better median survival (24 months) than TCM alone and much better than PBC alone. None of the patients that received TCM alone survived > 54 months, whereas 18% of TCM and PBC patients survived much longer. Over the observation period of 3 - 120 months, survivals of TCM and TT, TCM and PBC and TT, and TCM and PBC were not different and therefore grouped as TCM and Western medicines. Median survival times of PBC alone and TCM alone were lower than that of TCM and Western medical treatments (p < 0.0001, 10, 17 and 27 months). CONCLUSIONS: Pulmonary stage IV adenocarcinoma patients with at least 3 months survival, treated with TCM alone have a significantly better survival than those treated with PBC alone. Adding Western PBC, TT or both to TCM further improves prognosis.

Jinfukang inhibits lung cancer metastasis by upregulating CX3CL1 to recruit NK cells to kill CTCs.

ETHNOPHARMACOLOGICAL RELEVANCE: Circulating tumor cells (CTCs) play an important role in tumor metastasis and may be a target for metastasis prevention. The traditional Chinese medicine Jinfukang functions to improve immunity, prevent metastasis, and prolong lung cancer patient survival periods. Yet, whether Jinfukang prevents metastasis by regulating immune cells to clearance CTCs is still unknown. AIM OF THE STUDY: To explore the anti-metastasis mechanism of Jinfukang from the perspective of regulating NK cells to clear CTCs. MATERIALS AND METHODS: CTC-TJH-01 cell was treated with Jinfukang. Cytokine chip was used to detect cytokines in cell culture supernatant. Lymphocyte recruitment assay was detected by Transwell and flow cytometry. Protein expression was analysis by Western blot. LDH kit was used to detect cytotoxicity. NOD-SCID mice used for tail vein injection to study lung metastasis. RESULTS: Jinfukang could promote the expression and secretion of the chemokine CX3CL1 by CTCs. In addition, Jinfukang could promote the recruitment of natural killer (NK) cells by CTCs and significantly increase the cytotoxic effect of NK cells on CTCs. Moreover, Jinfukang could upregulate the expression of FasL and promote the secretion of TNF-α by NK cells and that NK cells could induce the apoptosis of CTCs through the Fas/FasL signaling pathway. Finally, we confirmed that Jinfukang could promote NK cells to kill CTCs and then inhibit lung cancer metastasis in vivo. The above effects of Jinfukang could be partially reversed by an anti-CX3CL1 mAb. CONCLUSIONS: These results suggest that Jinfukang may prevent lung cancer metastasis by enhancing the clearance of CTCs in the peripheral blood by NK cells, providing evidence for the anti-metastasis effect of Jinfukang.

Jinfukang regulates integrin/Src pathway and anoikis mediating circulating lung cancer cells migration.

ETHNOPHARMACOLOGICAL RELEVANCE: Metastasis is the main cause of death in lung cancer patients. Circulating tumor cells (CTCs) may be an important target of metastasis intervention. Previous studies have shown that Jinfukang could prevent the recurrence and metastasis of lung cancer, and we have established a circulating lung tumor cell line CTC-TJH-01. However, whether Jinfukang inhibition of lung cancer metastasis is related to CTCs is still unknown. AIM OF THE STUDY: To further explore the mechanism of Jinfukang in anti-metastasis of lung cancer from the perspective of intervention of CTCs. MATERIALS AND METHODS: CTC-TJH-01 and H1975 cells were treated with Jinfukang. Cell viability was detected by CCK8, and the cell apoptosis was detected by flow cytometry. Transwell was used to detected cell migration and invasion. Cell anoikis was detected by anoikis detection kit. Protein expression was analysis by Western blot. RESULTS: Jinfukang could inhibit the proliferation, migration and invasion of CTC-TJH-01 and H1975 cells. Besides, Jinfukang could also induce anoikis in CTC-TJH-01 and H1975 cells. Analysis of the mRNA expression profile showed ECM-receptor interaction and focal adhesion were regulated by Jinfukang. Moreover, it was also find that Jinfukang significantly inhibited integrin/Src pathway in CTC-TJH-01 and H1975 cells. When suppress the expression of integrin with ATN-161, it could promote Jinfukang to inhibit migration and induce anoikis in CTC-TJH-01 and H1975 cells. CONCLUSIONS: Our results indicate that the migration and invasion of CTCs are inhibited by Jinfukang, and the mechanism may involve the suppression of integrin/Src axis to induce anoikis. These data suggest that Jinfukang exerts anti-metastatic effects in lung cancer may through anoikis.

Multidisciplinary and Comprehensive Chinese Medicine for Advanced Non-Small Cell Lung Cancer Patients: A Retrospective Study of 855 Cases.

OBJECTIVE: To investigate the effects of multidisciplinary and comprehensive Chinese medicine (CM) treatments on progression-free survival (PFS) and median survival time (MST) in patients with advanced non-small cell lung cancer (NSCLC) and identify factors that influence progression and prognosis. METHODS: Clinical data of 855 patients with advanced NSCLC who received multidisciplinary and comprehensive CM treatments at Longhua Hospital from January 2009 to December 2018 were retrospectively analyzed. Univariate analysis was performed by the Kaplan-Meier method and log-rank sequential inspection. Multivariate analysis of significant variables from the univariate analysis was performed with Cox regression modeling. Key factors correlated to progression and prognosis were screened out, and a Cox proportional hazard model was established to calculate the prognostic index. RESULTS: The PFS and MST of 855 advanced NSCLC patients were 9.0 and 26.0 months, respectively. The 1-, 2-, 3-, and 5-year survival rates were 79.2%, 54%, 36.2%, and 17.1%, respectively. Gender, pathologic type, and clinical stage were independent prognostic risk factors; surgical history, radiotherapy, treatment course of Chinese patent medicine, intravenous drip of Chinese herbal preparation, duration of oral administration of Chinese herbal decoction (CHD), and intervention measures were independent prognostic protective factors. Gender was an independent risk factor for progression, while operation history and oral CHD administration duration were independent protective factors (all P<0.05). Women with stage IIIb-IIIc lung adenocarcinoma had the best outcomes. CONCLUSIONS: Female patients have lower progression risk and better prognoses than male patients, younger patients have higher progression risk but better long-term prognoses than the elderlys, and patients with lower performance status scores are at lower risk for progression and have better prognoses. Comprehensive CM treatments could significantly reduce progression risk, improve prognosis, and prolong survival time for patients with advanced NSCLC. This treatment mode offers additional advantages over supportive care alone.

Proteomics analysis of tumor exosomes reveals vital pathways of Jinfukang inhibiting circulating tumor cells metastasis in lung cancer.

ETHNOPHARMACOLOGICAL RELEVANCE: Jinfukang has long been used for the clinical treatment of lung cancer. Previous studies have shown that Jinfukang can induce the apoptosis of circulating tumor cells by intervening ROS-mediated DNA damage pathway. However, whether Jinfukang can inhibit the metastasis of circulating tumor cells and its mechanism are still unclear. AIM OF THE STUDY: To further investigate the mechanism of Jinfukang in anti-metastasis of lung cancer from the perspective of intervention of tumor exosomes. MATERIALS AND METHODS: The invadopodia formation was determined with immunofluorescence. Invasion and migration were detected using the Transwell assay. Ultracentrifugation was used to isolate exosomes. Exosomes were characterized by electron microscopy, nanoparticle tracking analysis and immunoblotting, and the protein profile was evaluated by proteomic analysis. The molecular functions, biological processes and signaling pathway enrichment analysis were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Key differentially expressed proteins were verified by Western blot. RESULTS: Jinfukang can inhibit the expression of MMP14, cortactin, Tks5 and the formation of invadopodia of CTC-TJH-01 cells. Furthermore, Jinfukang can significantly inhibit the invasion and migration of CTC-TJH-01 cells. The diameter of exosomes extracted from the CTC-TJH-01 cells treated by Jinfukang was 30-100 nm, and the exosomal markers CD63, CD81 and TSG101 were expressed. We identified 680 deferentially expressed proteins. Gene oncology analysis indicated that exosomes were mostly derived from plasma membrane and mainly involved in protein localization and intracellular signaling. The ingenuity pathway analysis showed that the EGF pathway was significantly inhibited, whereas the GP6 signaling pathway was significantly activated. We also confirmed that Jinfukang inhibited the expression of EGF pathway-related proteins in CTC-TJH-01 cells. Besides, when EGF was used to activate EGF signaling pathway, the inhibition of Jinfukang on CTC cell metastasis was reversed. CONCLUSION: Jinfukang inhibits the metastasis of CTC-TJH-01 cells through the EGF pathway.

Jingfukang induces anti-cancer activity through oxidative stress-mediated DNA damage in circulating human lung cancer cells.

BACKGROUND: Metastasis is the main cause of lung cancer death. As a seed of metastasis, circulating tumor cells are an important target for metastasis intervention. The traditional Chinese medicine, Jinfukang, has been clinically available for the treatment of non-small cell lung cancer (NSCLC). In this study, we investigated the action and underlying mechanisms of Jinfukang against circulating lung tumor cells. METHODS: The cell counting kit-8 (CCK-8), colony formation and cell cycle assays were used to study the cell proliferation ability. Flow cytometry was used to detect the apoptosis and the expression level of ROS and Caspase-3. Comet and TUNEL assays were used to detect DNA damage. DNA damage related pathway protein was detected by western blot. RESULTS: Jinfukang significantly inhibits the proliferation of CTC-TJH-01 cells by inducing G1 phase arrest and inhibits their colony formation in a dose-dependent manner. Moreover, Jinfukang induces apoptosis in CTC-TJH-01 cells through the ROS-mediated ATM/ATR-p53 pathway and DNA damage. CONCLUSIONS: Our findings suggest that Jinfukang may be a potential drug for lung cancer metastasis.

Traditional Chinese Medicine Treatment as Adjuvant Therapy in Completely Resected Stage IB-IIIA Non-Small-Cell Lung Cancer: Study Protocol for a Multicenter, Double-Blind, Randomized, Placebo-Controlled Trial.

Adjuvant chemotherapy (AC) has been proven to yield an approximately 5% improvement in 5-year survival for patients with early-stage non-small-cell lung cancer. With such small gains in survival, the optimal treatment regimen remains to be established. Traditional Chinese medicine (TCM) treatment in combination with AC is frequently used in China. The efficacy and safety of this integrated approach should be scientifically evaluated. We present the rationale and study design of the Combined Adjuvant Chemotherapy and Traditional Chinese Medicine (ACTCM) trial (ChiCTR-IPR-16009062). The ACTCM trial, a prospective multicenter double-blind randomized placebo-controlled study, will recruit 312 patients overall from 5 clinical research centers in China. Within 6 weeks of the thoracic surgery, eligible participants with stages IB-IIIA non-small-cell lung cancer will be randomly assigned in a 1:1 ratio to either the treatment or control group. Patients in the treatment group will receive AC combined with TCM herbal treatment for 4 cycles, then TCM herbal plus injection treatment for 4 cycles. Patients in the control group will receive AC combined with TCM placebo for 4 cycles and then TCM placebo for 4 cycles. Treatment will be discontinued if disease progression or unacceptable toxicity occurs. The primary end point is 2-year disease-free survival. Secondary end points include disease-free survival and quality of life. Other end points are TCM symptoms, performance status, and safety of the regimens. Recruitment started in October 2016 and is ongoing.

Feiji Recipe inhibits the growth of lung cancer by modulating T-cell immunity through indoleamine-2,3-dioxygenase pathway in an orthotopic implantation model.

OBJECTIVE: Escape from the body's immune response is a basic characteristic of lung cancer, and indoleamine-2,3-dioxygenase (IDO) plays a key role in mediating immune escape of non-small-cell lung cancer, which leads to recurrence and metastasis. Feiji Recipe, a compound Chinese herbal medicine, has the effect of stabilizing lesions and prolonging survival in patients with lung cancer. The purpose of this study was to investigate the mechanisms underlying the anticancer properties of Feiji Recipe. METHODS: An orthotopic transplant model of mouse Lewis lung cancer, with stable expression of IDO gene, was established in C57BL/6 mice. Optical imaging was used to observe the effects of Feiji Recipe in the treatment of lung cancer in vivo. The effects of Feiji Recipe on the proliferation of mouse Lewis lung cancer cell line 2LL, 2LL-enhanced green fluorescent protein (2LL-EGFP) and 2LL-EGFP-IDO were investigated, and the apoptosis of T-cells was examined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide using flow cytometry. Chemical composition of Feiji Recipe was validated by high-performance liquid chromatography. RESULTS: Compared to the control group, the survival of animals treated with Feiji Recipe was significantly prolonged (P = 0.0074), and the IDO protein level decreased (P = 0.0072); moreover, the percentages of CD4+CD25+ T-cells and Foxp3+ T-cells were significantly decreased (P < 0.05). The molecular mechanism of Feiji Recipe against lung cancer may relate to the regulation of immune cells, such as T-cells and regulatory T-cells. CONCLUSION: The molecular mechanism of Feiji Recipe in treatment of lung cancer is to restore the function of T-cells in the cancer microenvironment through interfering with the IDO pathway.

In Metastatic Non-small cell Lung Cancer Platinum-Based Treated Patients, Herbal Treatment Improves the Quality of Life. A Prospective Randomized Controlled Clinical Trial.

Background: According to clinical experience, Traditional Chinese Medicine (TCM) herbs added to platinum-based therapy (PBT) improve the Quality of Life (QOL) in metastatic non-small cell lung cancer (NSCLC) patients, but this must be prospectively validated. Patients and Methods: Based on clinical impressions regarding the effect of adding TCM herbs to platinum-based chemotherapy, we anticipated that 2 × 21 patients would be sufficient to obtain significant results with an α < 0.05 and power (1 - ß) of 90%. To be on the safe side, we enrolled at least 28 patients in each group. In a prospective randomized controlled trial, 61 uniquely defined consecutive patients (PBT+PLACEBO, N = 32; PBT+TCM, N = 29) with stage IIIB-IV, Eastern Cooperative Oncology Group (ECOG) performance scores (PS) = 0-1 and TCM syndrome combined Qi-Yin deficiency were enrolled. These 61 patients were selected from originally 154 consecutive stage IIIB-IV lung cancer patients in the enrollment period. Patients were hospitalized and strictly controlled/surveyed during the entire 2-month treatment period, to guarantee use of or abstinence from TCM herbal and placebo fluids. Occurrence of nausea-vomiting, QOL by Functional Assessment of Cancer Therapy-Lung (FACT-L) scales and changes in ECOG "improved and stable rates" were compared before and after two treatment cycles. Results: Before treatment, the clinico-pathologic and QOL features in PBT+PLACEBO and PBT+TCM patients did not differ (P > 0.10). The only side effects attributed by some of the patients to the TCM herbs were transient, mild gastric/abdominal heaviness in the first 2 weeks, but these also occurred amongst the PBT+PLACEBO patients (17 and 13%, P > 0.10). The incidence rates of nausea during treatment were 17% in PBT+TCM versus 75% in PBT+PLACEBO; vomiting rates were 14 and 56% (P < 0.0001 and 0.002). Moreover, ECOG "improved and stable rates" were 90% in the PBT+TCM versus 69% in the PBT+PLACEBO group (P = 0.04). In PBT+TCM patients, FACT-L social/familial and functional subscales were better after 2 months' treatment (P = 0.02 and 0.03). Contrarily, in PBT+PLACEBO patients, the QOL variables total score, physical and emotional subscales were worse after PBT treatment (P = 0.03, 0.0001, and 0.003). Conclusion: In stage IIIB-IV ECOG-PS = 0-1 NSCLC patients with Qi-Yin deficiency and platinum-based chemotherapy, adding TCM herbal medication improves the QOL. As this category of patients constitutes 40% of all metastatic NSCLCs, these results could have significant clinical impact.

Effects of Chinese Medicine as Adjunct Medication for Adjuvant Chemotherapy Treatments of Non-Small Cell Lung Cancer Patients.

The aim was to evaluate the effects of traditional Chinese medicine (TCM) as a combination medication with adjuvant chemotherapy on postoperative early stage non-small cell lung cancer (NSCLC) patients. The 314 patients with completely resected stage IB, II or IIIA cancers were assigned into vinorelbine plus cisplatin/carboplatin (NP/NC) (control, n = 158) and NP/NC with additional TCM (intervention, n = 156) groups. The primary endpoint was QOL scores; secondary endpoints were the toxicity and safety of the regimens. The NP/NC regimen caused mild (grade 1 or 2) non-hematologic toxic effects in the patients comprising vomiting (43.6%), fatigue (36.9%), pain (23%), dry mouth (27.6%) and diarrhea (7.9%). The incidence of adverse events was significantly lower in the intervention group than in the control group (0.57% vs 4.02%, P = 0.037). Transient severe (grade 3 or 4) hematological toxic effects occurred less often (hemoglobin reduction (11.9 vs 22.5 percent) and total bilirubin increased (to 42.1 vs 46.2%) in the intervention compared to the control group during the 2nd chemotherapy cycle. When combined with adjuvant chemotherapy, TCM led to partial relief of symptoms in addition to a reduction of side-effects and adverse events caused by the NP/NC regimens.

[Inhibitory Effect of Feiji Recipe on IDO Induced Immune Escape on the Murine Model of Lewis Lung Carcinoma].

OBJECTIVE: To study the effect of Feiji Recipe (FR) intervening indoleamine 2,3-dioxygenase (IDO) induced immune escape on the murine model of Lewis lung carcinoma. Methods Totally 48 C57BL/6 mice inoculated with Lewis lung cancer cells transfected with human (enhanced green fluorescent protein,EGFP)-IDO gene were divided into four groups according to radom digit table, i.e., the model group (administered with normal saline by gastrogavage) , the Chinese medicine group (treated with FR Decoction at the daily dose of 100 mg/g by gastrogavage), the 1-methyl-D-trytaphan (1-MT) group (administered with 1-MT mixed liquor at the daily dose of 100 mg/kg by gastrogavage), and the Paclitaxel group (treated with Paclitaxel at the daily dose of 15 mg/kg by peritoneal injection), 12 in each group. The intervention was started from the 2nd day of modeling. The survival time was observed in 24 of them. Ratios of CD4+ CD25+ FoxP3+ regulatory T cells (Treg) in the spleen were detected in the rest 24 mice by flow cytometry respectively. RESULTS: Compared with the model group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells remarkably decreased in the Chinese medicine group, the 1-MT group, and the Paclitaxel group (P < 0. 01). Compared with the Paclitaxel group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells decreased significantly in the 1-MT group (P < 0.05). CONCLUSION: FR could inhibit the proliferation of lung cancer cells and immune eseape, improve the immune function, and prolong the survival of tumor-bearing mice.

Traditional Chinese Medicine treatment as maintenance therapy in advanced non-small-cell lung cancer: A randomized controlled trial.

OBJECTIVES: Maintenance therapy for patients with advanced non-small-cell lung cancer (NSCLC) is an increasingly hot topic in the field of clinical NSCLC research. This study aimed to evaluate the effects of Traditional Chinese Medicine (TCM) treatment as maintenance therapy on time to progression (TTP), quality of life (QOL), overall survival (OS) and 1-year survival rate in patients with advanced NSCLC. METHODS: This study was conducted as a randomized, controlled, open-label trial. 64 non-progressive patients who responded to initial therapy were randomized 1:1 to the TCM arm (treated with herbal injection (Cinobufacini, 20ml/d, d1-d10), herbal decoction (d1-d21) and Chinese acupoint application (d1-d21), n=32) or to the chemotherapy arm (treated with pemetrexed (non-squamous NSCLC, 500mg/m(2), d1), docetaxel (75mg/m(2), d1) or gemcitabine (1250mg/m(2), d1 and d8), n=32). Each therapy cycle was 21 days. They were repeated until disease progression, unacceptable toxicity, or until the patients requested therapy discontinuation. The primary end point was TTP; the secondary end points were QOL, OS and 1-year survival rate. "Intention-to-treat" analysis included all randomized participants. RESULTS: TCM treatment prolonged median TTP for 0.7 months compared with chemotherapy, but it was not statistically significant (3.0 months vs. 2.3 months, P=0.114). Median OS time for TCM treatment did not offer a significant advantage over for chemotherapy (21.5 months vs. 18.8 months, P=0.601). 1-year survival rate of TCM treatment significantly improved than that of chemotherapy (78.1% vs. 53.1%, P=0.035). TCM treatment can significantly improve QOL when compared to chemotherapy as assessed by EORTC QLQ-C30 and EORTC QLQ-LC13 QOL instruments. CONCLUSIONS: TCM maintenance treatment had similar effects on TTP and OS compared with maintenance chemotherapy, but it improved patients' QOL and had higher 1-year survival rate. TCM Maintenance treatment is a promising option for advanced NSCLC patients without progression following first-line chemotherapy.

[Treatment of Radical Resected NSCLC by Chinese Medicine Combined with Adjuvant Chemother- apy: a Clinical Study].

OBJECTIVE: To evaluate the efficacy of Chinese medicine (CM) combined adjuvant chemotherapy in postponing relapse and metastasis of radical resected Ib-IIIa stage non-small cell lung cancer (NSCLC) patients, and to explore its effect in improving their quality of life (QOL) and clinical symptoms. METHODS: We designed a cohort study of 336 radical resected Ib-IIIa NSCLC patients by analyzing disease free survival (DFS) using Log-rank test. They were randomly assigned to the control group (155 cases, treated by adjuvant chemotherapy group) and the test group (181 cases, treated by adjuvant chemotherapy combined CM). By using controlled method, 60 radical resected NSCLC patients undergoing NP/NC program in 2012 (vinorelbine 25 mg/m2, combined with cisplatin 75 mg/m2 on day 1 and day 8/on day 1 or on day 1, 2, and 3; or carboplatin AUC = 5 on day 1) were assigned to the control group (29 cases) and the test group (31 cases). QOL scores (using EORTC QLQ-LC43 questionnaire) and TCM symptoms scores were compared between the two groups before chemotherapy, peri-chemotherapy (one day before the 2nd course of chemotherapy) , and after chemotherapy (20 days after ending the 4th course of chemotherapy). RESULTS: (1) The median DFS was longer in the test group than in the control group, but with no statistical difference between the two groups (42.73 months vs 35.57 months , P = 0.179). In the subgroup analysis, there was statistical difference in IIIa stage DFS. The median IIIa stage DFS of was longer in the test group than in the control group with statistical difference (27.87 months vs 19. 93 months, P = 0.047). (2) In the control study, repeated measured data indicated there was significant difference in physical functions between the two groups (P < 0.05). Total scores for health states decreased more in the test group than in the control group, but with no statistical difference (P > 0.05). Scores for constipation and CM syndrome scores were higher in the test group than in the control group (P < 0.05). CONCLUSIONS: CM had advantages in postponing DFS of radical resected NSCLC patients, especially in IIIa stage. CM could improve their QOL and clinical symptoms during adjuvant chemotherapy.

Chemotherapy in conjunction with traditional Chinese medicine for survival of elderly patients with advanced non-small-cell lung cancer: protocol for a randomized double-blind controlled trial.

BACKGROUND: Traditional Chinese medicine (TCM) is considered an important complementary therapy with beneficial effects for cancer patients. Elderly patients with non-small-cell lung cancer (NSCLC) are a complex patient group with increasing co-morbidity and shrinking physiological reserve, and may derive substantial benefit from the supportive aspects of TCM. Researchers from Shanghai Longhua Hospital found that qi and yin deficiency is a common syndrome in patients with stage III or IV lung cancer. This project was designed to study the combination of single-agent chemotherapy with TCM methods of benefiting qi and yin in elderly patients with advanced NSCLC. METHODS AND DESIGN: This is a double-blind controlled, multi-center, and prospective study with randomly selected participants from elderly NSCLC patients in China. Seventy-six patients who meet the inclusion criteria will be allocated into two groups, which will receive treatments of 3-week single-agent chemotherapy with TCM or placebo for four cycles. Progression-free survival (PFS) is the primary end point, and the secondary end points are overall survival, objective response rate, time-to-progression, and quality of life (EORTC QLQ-LC43, and TCM syndrome score). Meanwhile, other end points such as toxicity, side effects and safety of the treatments will be assessed. DISCUSSION: Results from this study may provide evidence on the effectiveness, and parameters for the usage of single-agent chemotherapy combined with or without TCM on PFS of elderly patients with NSCLC. TRIAL REGISTRATION: ClinicalTrials.gov. (Identifier: NCT01780181).

Multi-center randomized double-blind controlled clinical study of chemotherapy combined with or without traditional Chinese medicine on quality of life of postoperative non-small cell lung cancer patients.

BACKGROUND: Traditional Chinese medicine (TCM) is a widely applied complementary therapy for cancer patients. It can reduce the chemical drugs induced toxic effects to improve the quality of life (QOL). This study applies the highest quality of clinical trial methodology to examine the role of TCM in improving QOL of postoperative non-small-cell lung cancer patients. METHODS AND DESIGN: This study is a multi-center, randomized, placebo-controlled, double-blind trial. Four hundred eighty patients will be recruited into seven different research centers in China. These patients that meet the inclusion criteria will be randomized into either a treatment group or a placebo group. Each group will receive treatments of 3-weekly chemotherapy with TCM or placebo for four cycles. The primary outcome will involve the evaluation of QOL and the secondary outcome assessments will include two-year disease-free survival rate and disease-free survival. Other efficacy assessments are changes of TCM symptoms and toxicity. Side effects and safety profile of the therapy would be evaluated at the same time. The investigators expect that TCM therapy combined with chemotherapy is superior to chemotherapy solely in terms of QOL improvement and disease-free survival extension. "Intention-to-treat" analysis will include all randomized participants. DISCUSSION: The results from the clinical trial will provide evidence for the effectiveness of chemotherapy combined with or without TCM in QOL of postoperative NSCLC patients. TRIAL REGISTRATION: Clinical Trials.gov (Identifier: NCT01441752).

[Study on the effect of Feiji Decoction for soothing the liver combined with psychotherapy on the quality of life for primary lung cancer patients].

BACKGROUND AND OBJECTIVE: Lung cancer is the most common type among all malignant tumors, bringing huge pain and mood disorders to patients suffering from it. This study aims to evaluate the effect of the Feiji Decoction for soothing the liver combined with psychotherapy for depression and anxiety on patients with primary lung cancer. It also aims to further explore the relationship between depression and anxiety. METHODS: A total of 118 patients with primary non-small cell lung cancer were randomly divided into two groups. The combined therapy group consisted of 57 patients who were treated with Feiji Decoction for soothing the liver and psychotherapy combined with chemotherapy. The control group consisted of 61 patients who were treated with chemotherapy only. Both groups were observed for two treatment courses. The Zung Self-reported Depression Scales (SDS) and Zung Self-reported Anxiety Scales (SAS) were used to assess the patients' psychology status in both groups before and after treatment scales. RESULTS: After treatment, the depression and anxiety scores of the therapy group remarkably decreased compared with scores before treatment, indicating a statistical significance (P<0.01). In comparison, after treatment, the depression and anxiety scores of the control group significanfly increased compared with scores before treatment, indicating a statistical significance (P<0.01) as well. The depression and anxiety scores of the therapy group significanfly decreased compared with scores of the control group, showing statistical significance (P<0.01). Thus, depression and anxiety score has a close co-relationship, showing significant positive correlation (P<0.01). CONCLUSIONS: Feiji Decoction for soothing the liver combined with psychotherapy can alleviate depression and anxiety in patients with primary lung cancer. This therapy has good clinical therapeutic effect.
