Kanglaite injection combined with chemotherapy versus chemotherapy alone in the treatment of advanced non-small cell lung carcinoma

Kanglaite (Coix Seed Extract) as Adjunctive Therapy in Cancer: Evidence Mapping Overview Based on Systematic Reviews With Meta-Analyses

Background: Several quantitative systematic reviews of Kanglaite (KLT), an herb preparation used to treat cancer and malignant pleural effusion, have been published in recent years. However, the clinical evidence reported in these studies has not been pursued further and the methodological quality of these meta-analyses remains unknown. Therefore, an overview was designed to map the evidence landscape based on the published meta-analyses on KLT in cancer treatment.

Methods: Two bibliographic databases (PubMed and Embase) were searched from inception to 25 November 2021. Two independent reviewers were involved in study selection, data abstraction, and methodological quality assessment using AMSTAR 2. The principal features of publications and the clinical outcomes of efficacy and safety were synthesized narratively, and results of methodological quality were reported as frequencies and percentages with the corresponding 95% confidence intervals. The evidence map was used to visualize the overall quality. Excel 2016 and Stata 17/SE were used for data analysis.

Results: Thirteen meta-analyses published in English were included for in-depth analysis. Among them, the year of publication ranged from 2008 to 2021, and the number of included patients ranged from 488 to 2,964. Regarding the cancer type, seven articles focused on non-small cell lung cancer, two on malignant pleural effusion, and four reviews on digestive system malignancies, such as hepatocellular carcinoma and pancreatic cancer. Almost all included meta-analyses reported that KLT as adjunctive therapy could improve various efficacy outcomes (such as disease response rates, quality of life, immune indicators) and reduce the rate of occurrence of adverse reactions, such as nausea and vomiting, leukopenia, and anemia. In terms of their methodological quality, three meta-analyses were of low quality, whereas 10 studies were critically low in quality. The methodological flaws main involved items 2 (“predesigned protocol and registration informatio’’), 3 (“rationale of study design for inclusion”), 4 (“comprehensive search strategy’’), 5 (“literature selection in duplicate’’), 7 (“list of excluded studies with reasons’’), 8 (“adequate information on included studies’’), 10 (“funding support for included primary studies’’), and 12 (“evaluation of the potential impact of risk of bias’’) based on the AMSTAR 2 tool.

Conclusion: Current evidence reveals that KLT is effective and safe as an adjunctive treatment for non-small cell lung cancer, malignant pleural effusion, and digestive system malignancies (such as hepatocellular carcinoma). However, the results assessed in this overview should be further verified using well-designed and clearly reported clinical trials and meta-analyses of KLT.

Enhancement of Anti-Proliferative Activity of the Extracts from Dehulled Adlay by Fermentation with Bacillus subtilis

Dehulled adlay was fermented with Bacillus subtilis BJ3-2, the anti-proliferative activities of the extracts from fermented dehulled adlay were investigated with six types of tumor cells, and then the bioactive components and the anti-proliferative mechanism were primarily explored. Results showed that all the extracts of B.subtilis-fermented dehulled adlay (BDA) and dehulled adlay (DA) had no inhibition effect on human embryonic kidney 239T cells. The anti-proliferative activities of the extracts from BDA against six types of tumor cells were almost always significantly higher than DA. Compared with others, the n-butanol extract of BDA (BDA-Nb) exhibited stronger anti-proliferative activities against human leukemia K562 cells and human non-small cell lung cancer A549 cells. Importantly, the anti-proliferative activity of fermented dehulled adlay against K562 cells was firstly discovered. Meanwhile, BDA-Nb was rich in tetramethylpyrazine, γ-aminobutyric acid, protocatechuic, 2,3,4-trihydroxybenzoic, chlorogenic, p-hydroxybenzoic, caffeic, trans-cinnamic, ferulic acids, and rutin. BDA-Nb induced the proliferative inhibition of K562 and A549 cells due to abnormal cell morphology, the increased cell population in G1 phase and apoptosis rate, the downregulation of Bcl-2, and the upregulation of Bax and caspase-3/8/9. These results indicate that dehulled adlay fermented with B.subtilis could be a potential therapeutic agent for leukemia and lung cancer.

Coix Seed May Affect Human Immune Function

Coix ( Coix lacryma-jobi Linné . var . mayuen Stapf) is, unlike many herbs used in Chinese traditional medicines, often used as a single agent. Coix seed has its specific constituents coixenolide and coixol. This review summarizes the effects of coix seed on human pathology and physiology, and the roles of coixenolide and coixol on the effects. The comprehensive literature search was conducted using PubMed, Citation Information by National Institute of Informatics of Japan (CiNii), University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR), and ClinicalTrials.gov databases. Some studies suggest that coix seed promotes the spontaneous regression of viral infections of the skin. Meanwhile, kanglite, a purified oil agent used for cancer therapy, has been implied to increase the ratio of CD4 + T cells in the peripheral blood of cancer patients undergoing treatment. These studies seem to indicate that coix seed may affect cellular immune function. However, there are limitations to the individual studies on which the above consideration is based, and thereby, it is not conclusive what specific immune or clinical indices coix seed affects. In addition, the effects of coixol on human immune function have not been clarified. Therefore, coix seed seems promising for health promotion and presents a challengeable and attractive theme for natural product chemists, pharmacologists, immunologists, and clinicians.

Combination of first-line chemotherapy with Kanglaite injections versus first-line chemotherapy alone for advanced non-small-cell lung cancer: study protocol for an investigator-initiated, multicenter, open-label, randomized controlled trial

Background

Non-small-cell lung cancer (NSCLC) is usually diagnosed at an advanced stage, and chemotherapy is the main treatment for this disease. Kanglaite injections (KLTi) have been widely used for the treatment of cancer in China. KLTi combined with chemotherapy could improve the short-term efficacy, quality of life, and performance status for NSCLC compared with chemotherapy alone. This trial aims to assess the long-term efficacy and safety of KLTi in combination with chemotherapy for the treatment of advanced NSCLC.

Methods

This will be an investigator-initiated multicenter open-label randomized controlled trial. We will randomly assign 334 eligible participants with stage IIIA-IV NSCLC to the treatment or control groups in a 1:1 ratio. Patients in both groups will be administered 4–6 cycles of first-line platinum-based double chemotherapy regimens. Patients with complete response, partial response, or stable disease after 4–6 cycles will receive non-platinum single-agent chemotherapy. Patients in the treatment group are to receive intravenous KLTi 200 ml per day continuously for 14 days, commencing on the first day of chemotherapy. The treatment will be discontinued at the time of disease progression or until unacceptable toxicity is noted. The follow-up will be conducted every 2 months until death, loss of follow-up, or 12 months from randomized enrollment. The primary outcome will be progression-free survival (PFS). The secondary outcomes will be the objective response rate, 1-year survival rate, quality of life, living ability, and blood lipids. The safety outcome will be the rate of adverse events.

Discussion

This study will be the first randomized controlled trial in which PFS is used as the primary outcome to test whether KLTi combined with first-line chemotherapy has superior efficacy and reduced toxicity compared to chemotherapy alone in advanced NSCLC. This will also be the first clinical study to observe the effects of KLTi on blood lipids.

The clinical efficacy and safety of kanglaite adjuvant therapy in the treatment of advanced hepatocellular carcinoma: A PRISMA-compliant meta-analysis

Kanglaite, a type of Chinese medicine preparation, is considered a promising complementary therapy option for advanced hepatocellular carcinoma (HCC). Although an analysis of the published literature has been performed, the exact effects and safety are yet to be systematically investigated. Therefore, we conducted a wide-ranging online search of electronic databases to provide systematic conclusions; data from 31 trials with 2315 HCC patients were included. The results indicated that compared with conventional treatment (CT) alone, the combination of kanglaite with CT markedly prolonged patients’ 6-month overall survival (OS, P=0.003), 12-month OS (P<0.0001), 18-month OS (P=0.003), 24-month OS (P=0.03) and 36-month OS (P=0.0006) and significantly improved the overall response rate (odds ratio (OR) = 2.57, 95% confidence interval (CI) = 2.10–3.16, P<0.00001) and disease control rate (OR = 3.10, 95% CI = 2.42–3.97, P<0.00001) of patients. The quality of life (QoL), clinical symptoms and immune function of patients were also obviously improved after combined treatment. The incidence rates of nausea and vomiting (P=0.04), hepatotoxicity (P=0.0002), leukopenia (P<0.00001), thrombocytopenia (P<0.0001), gastrointestinal side effects (P=0.01) and fever (P<0.0009) were lower in the group receiving CT and kanglaite than in the group receiving CT alone. In summary, the combination of kanglaite and CT is safe and more effective in treating HCC than is CT alone, and its application in the clinic is worth promoting.

Kanglaite injection plus platinum-based chemotherapy for stage III/IV non-small cell lung cancer: A meta-analysis of 27 RCTs

BACKGROUND

Kanglaite injection (KLT) is a broad-spectrum anti-tumor drug, which is extracted from the seeds of the Chinese medicinal herb Coix lacryma-jobi, and has been widely used for the treatment of advanced lung cancer.

PURPOSE

To evaluate the combined effects of Kanglaite injection plus platinum-based chemotherapy (PBC) on patients with stage III/IV non-small cell lung cancer (NSCLC).

STUDY DESIGN

A systematic review and meta-analysis of randomized clinical trials (RCTs).

MATERIALS AND METHODS

Twelve databases were searched from their inceptions until July 05, 2019. All the RCTs comparing the efficacy and safety of Kanglaite injection plus PBC versus PBC alone were selected. Analyses were performed using Review Manager 5.3, Comprehensive Meta-Analysis 3.0 and Trial Sequential Analysis (TSA). Disease control rate (DCR) was defined as the primary endpoint, objective response rate (ORR), survival rate, quality of life (QOL), cellular immunity function, and toxicities were defined as the secondary endpoints.

RESULTS

Twenty-seven RCTs recruiting 2,243 patients with stage III/IV NSCLC were included. The results showed that, compared with PBC alone, Kanglaite injection plus PBC improved DCR (RR = 1.20, 95% CI 1.15-1.26, p < 0.00001), ORR (RR = 1.45, 95% CI 1.31-1.60, p < 0.00001), 1-year survival rate (RR = 1.20, 95% CI 1.02-1.43, p = 0.03), QOL (RR = 1.32, 95% CI 1.25-1.40, p < 0.00001), CD4⁺T cells (WMD = 4.86, 95% CI 4.00-5.73, p < 0.00001), CD4⁺/CD8⁺ ratio (WMD = 0.19, 95% CI 0.07-0.31, p < 0.002), and reduced severe toxicities by 59% (RR = 0.41, 95% CI 0.33-0.51, p < 0.00001). Most results were robust and the quality of evidence was from moderate to low.

CONCLUSIONS

Kanglaite injection in combination with PBC showed significantly higher efficacy than PBC alone in the treatment of stage III/IV NSCLC. Moreover, the combination therapy can improve cellular immunity and attenuate the severe toxicities caused by chemotherapy. However, high-quality RCTs are warranted to further assess the effects of the combined therapy.

Kanglaite Injection Combined with Chemotherapy versus Chemotherapy Alone for the Improvement of Clinical Efficacy and Immune Function in Patients with Advanced Non-Small-Cell Lung Cancer: A Systematic Review and Meta-Analysis

Recent advances have shown that immune checkpoint inhibitors are emerging as promising therapeutic targets to improve the quality of life in cancer patients. This meta-analysis was conducted to evaluate the influence of Kanglaite injection (KLTi) combined with chemotherapy versus chemotherapy alone on clinical efficacy, immune function, and safety for the treatment of advanced non-small-cell lung cancer (NSCLC). Several electronic databases, including PubMed, Web of Science, Wan-Fang, VMIS, EMBASE, Cochrane Library, CNKI, CBM, and MEDLINE, as well as grey literatures, were comprehensively searched from January 2000 to November 2019. Randomized controlled trials (RCTs) reporting outcomes of clinical efficacy and immune function were collected according to their inclusion and exclusion criteria. Cochrane Reviewers' Handbook 5.2 was applied to assess the risk of bias of included trials. STATA 13.0 and Review Manager 5.3 software were used for meta-analysis. Twenty-five RCTs comprising 2151 patients meeting the inclusion criteria were identified. Meta-analysis showed that compared with chemotherapy alone, KLTi plus the same chemotherapy significantly improved clinical efficacy, including complete response, partial response, stable disease, and progressive disease, as well as immune function, including CD³⁺, CD⁴⁺, CD⁸⁺, and CD⁴⁺/CD⁸⁺. There was a significant reduction in nausea and vomiting, thrombocytopenia, and leukopenia in combination treatments. However, the outcomes were limited because of the low quality and small sample size of the included studies. In conclusion, this work might provide beneficial evidence of KLTi combined with chemotherapy for improving clinical efficacy and immune function, as well as reducing the incidence of adverse events in advanced NSCLC patients. KLTi might be a beneficial therapeutic method for the treatment of advanced NSCLC. Due to the quality of the data, more rigorous and well-designed RCTs are needed to confirm these findings.

Coix seed oil ameliorates cancer cachexia by counteracting muscle loss and fat lipolysis

Background

Cancer cachexia is a cancer-induced multifactorial debilitating syndrome directly accounting for 20% of cancer deaths without effective therapeutic approaches. It is extremely urgent to explore effective anti-cachexia drugs to ameliorate muscle and fat loss in cachexia patients.

Methods

Lewis lung carcinoma bearing C57BL/6 mice were applied as the animal model to examine the therapeutic effect of Coix seed oil (CSO) on cancer cachexia. The food intake and body weight change were monitored every 3 days throughout the experiment. The IL-6 and TNF-α levels in serum were detected by ELISA assay. Several key proteins involved in muscle wasting and fat lipolysis were tested by Western blot to identify the potential mechanism of CSO.

Results

Administration of CSO through gavage significantly prevented body weight loss and ameliorated systemic inflammation without affecting food intake and tumor size. The weight and histological morphology of gastrocnemius muscle and epididymal adipose tissue in CSO-treated mice were also improved. In mechanism, we found that CSO decreased the expression of MuRF1 and the ratio of phospho-p65 (Ser536) to p65 in muscle tissue. Meanwhile, cancer-induced activation of HSL and AMPK was also inhibited by CSO administration.

Conclusion

Coix seed oil exerts an anti-cachexia pharmaceutical effect by counteracting muscle and adipose tissue loss most likely through regulating NF-κB-MuRF1 and AMPK-HSL pathway.

Efficacy and safety of Kanglaite injection combined with radiochemotherapy in the treatment of advanced pancreatic cancer: A PRISMA-compliant meta-analysis

BACKGROUND

Kanglaite (KLT) injection, a kind of Chinese medicine, is considered a promising complementary therapeutic option for malignant cancer treatment. This study aimed to systematically investigate the efficacy and safety of the combination of KLT injection and radiochemotherapy for the treatment of advanced pancreatic cancer (PC).

METHODS

Studies were identified by searching Cochrane Library, Web of Science, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biological Medicine Database (CBM), Wanfang database and Chinese Scientific Journal Database (VIP) before October 2018. The primary reported outcomes including efficacy, quality of life (QoL), and adverse events were systematically evaluated.

RESULTS

Data from 16 trials with 960 patients with advanced PC were included. Compared with radiochemotherapy alone, the combination of KLT injection and radiochemotherapy significantly improved the 1-year overall survival (OS, odds ratio [OR] = 2.58 95% CI: 1.12-5.93 P = .03), overall response (ORR, OR = 2.16 95% CI: 1.58-2.94 P <.00001) and disease control rates (DCR, OR = 2.50 95% CI: 1.84-3.38 P <.00001). The QoL of patients, who received a combination of radiochemotherapy and KLT injection, also improved compared with radiochemotherapy treatment alone as indicated by the increased quality of life improved rate (QIR, OR = 3.68 95%CI: 2.36-5.75 P <.00001), pain relief rate (PRR, OR = 3.70 95% CI: 2.23-6.14 P <.00001) and weight gain rate (WGR, OR = 3.69 95% CI: 2.22-6.13 P <.00001). Adverse events related to radiochemotherapy including gastrointestinal side effects, nephrotoxicity, leukopenia, thrombocytopenia, and myelosuppression were alleviated (P <.05) when KLT was injected to patients with PC.

CONCLUSIONS

Evidence from the Meta-analysis suggested that the combinational treatment of radiochemotherapy and KLT injection is more effective in advanced PC treatment than radiochemotherapy alone. Additionally, the combination therapy improved QoL of the patients. KLT injection can alleviate the adverse effects associated with the radiochemotherapy.

Apoptotic Pathway as the Therapeutic Target for Anticancer Traditional Chinese Medicines

Cancer is a leading cause of morbidity and mortality worldwide. Apoptosis is a process of programmed cell death and it plays a vital role in human development and tissue homeostasis. Mounting evidence indicates that apoptosis is closely related to the survival of cancer and it has emerged as a key target for the discovery and development of novel anticancer drugs. Various studies indicate that targeting the apoptotic signaling pathway by anticancer drugs is an important mechanism in cancer therapy. Therefore, numerous novel anticancer agents have been discovered and developed from traditional Chinese medicines (TCMs) by targeting the cellular apoptotic pathway of cancer cells and shown clinically beneficial effects in cancer therapy. This review aims to provide a comprehensive discussion for the role, pharmacology, related biology, and possible mechanism(s) of a number of important anticancer TCMs and their derivatives mainly targeting the cellular apoptotic pathway. It may have important clinical implications in cancer therapy.

Adlay (Coix lachryma-jobi L. var. ma-yuen Stapf.) Hull Extract and Active Compounds Inhibit Proliferation of Primary Human Leiomyoma Cells and Protect against Sexual Hormone-Induced Mice Smooth Muscle Hyperproliferation

Uterine leiomyomas, also known as fibroids, are benign neoplasms of the uterus and have a high incidence rate in women of reproductive age. Hysterectomy or myomectomy is the initial treatment, but fibroids will recur if the patient is still exposed to similar risk factors. Therefore, developing new therapeutic strategies are urgently necessary. In this study, the anti-proliferation effects of each fraction of adlay seeds were evaluated in uterine leiomyomas, and we identified the potential phytochemical compounds. We found that the ethyl acetate fraction of adlay hull (AHE-ea) appeared to be highly efficient in the anti-proliferation of rat uterine leiomyoma ELT3 cells and primary human uterine leiomyoma (hUL) cells. The proliferation of primary human normal uterine smooth muscle (UtSMC) and normal uterine myometrial (hUM) cells were also suppressed by AHE-ea. Two phytosterols, stigmasterol and β-sitosterol, were identified from AHE-ea fraction. Mice treated with AHE-ea and stigmasterol alone demonstrated reduced diethylstilbestrol/medroxyprogesterone 17-acetate (DES/MPA)-induced uterine myometrial hyperplasia, which is the critical step for the development of leiomyoma. Taken together, our results suggest that the AHE-ea fraction could be considered as a natural plant-based medicine in the prevention or treatment of uterine leiomyoma growth.

Multi-Component Herbal Products in the Prevention and Treatment of Chemotherapy-Associated Toxicity and Side Effects: A Review on Experimental and Clinical Evidences

Chemotherapy is nowadays the main treatment of human cancers. Chemotherapeutic agents target rapidly dividing cancer cells to suppress tumor progression, however, their non-specific cytotoxicity often leads to significant side effects that might be intolerable to cancer patients. Multi-component herbal products have been used for thousands of years for the treatment of multiple human diseases. This study aims to systematically summarize and evaluate the experimental and clinical evidences of the efficacy of multi-component herbal products in improving chemotherapy-induced side effect. Literature was retrieved from PubMed database and evaluated based on the side effects described. Multi-component herbal products were found to be effective in ameliorating the neurotoxicity, gastrointestinal toxicity, hematological toxicity, cardiotoxicity, hepatotoxicity and nephrotoxicity. Both experimental and clinical evidences were found, indicating the potential of applying multicomponent herbal products in the clinical treatment of chemotherapy-induced side effects. However, the lack of mechanistic and pharmacokinetic studies, inconsistency in product quality, as well as insufficient clinical evidence suggested that more investigations are urgently necessary. In all, our review shed light on the potential of using multi-component herbal products in the clinical management of chemotherapy-induced toxicity and side effects. We also discussed the potential threats of natural products for cancer treatment and compared the advantages of using herbs to conventional chemical drugs.

Oral kanglaite injection (KLTI) attenuates the lung cancer-promoting effect of high-fat diet (HFD)-induced obesity

Obesity is a risk factor for cancer and cancer-related mortality, however, its role in lung cancer progression remains controversial. This study aimed to assess whether high-fat diet (HFD)-induced obesity promotes lung cancer progression and whether the promotion can be decreased by Kanglaite injection (KLTI). In vivo, HFD-induced overweight or obesity increases the lung carcinoma incidence and multiplicity in a urethane-induced lung carcinogenic model and cancer-related mortality in a LLC allograft model by increasing oxidative stress and cellular signaling molecules including JAK, STAT3, Akt, mTOR, NF-κB and cyclin D1. These changes resulted in increases in vascular disruption and the lung water content, thereby promoting lung epithelial proliferation and the epithelial-mesenchymal transition (EMT) during carcinogenesis. Chronic KLTI treatment substantially prevented the weight gain resulting from HFD consumption, thereby reversing the metabolic dysfunction-related physiological changes and reducing susceptibility to lung carcinogenesis. In vitro, KLTI significantly suppressed the proliferation and induced apoptosis and differentiation in 3T3-L1 preadipocyte cells and attenuated endothelial cell permeability in HUVECs. Our study indicates that there is a potential relationship between obesity and lung cancer. This is the first study to show that obesity can directly accelerate carcinogen-induced lung cancer progression and that KLTI can decrease the lung cancer-promoting effect of HFD-induced obesity.

Herbal compound Teng-Long-Bu-Zhong-Tang inhibits metastasis in human RKO colon carcinoma

Metastasis is one of the primary obstacles to the successful treatment of colorectal cancer. Teng-Long-Bu-Zhong-Tang (TLBZT) is a modern Chinese herbal formula that may be useful in the treatment of metastatic colorectal cancer. The present study evaluated the effects of TLBZT on lung metastasis in human RKO colon carcinoma cells injected into mice via the tail vein. The results demonstrated that TLBZT inhibited the metastasis of human RKO colon carcinoma cells to the lungs. TLBZT downregulated the expression of LOX and hypoxia-inducible factor 1α. TLBZT also inhibited the expression of integrins αV and β3 and the phosphorylation of focal adhesion kinase. These results indicate that TLBZT inhibits the lung metastasis of RKO colon carcinoma by regulating the expression of multiple genes. The results of the present study provide a new basis for the management of colorectal cancer metastasis using treatments derived from Chinese herbs.

Kanglaite sensitizes colorectal cancer cells to Taxol via NF-κΒ inhibition and connexin 43 upregulation

Taxol, a first-line anti-tumour drug, has low effectiveness against colorectal cancer. Combination with other agents is an effective strategy to enhance Taxol cytotoxicity. Kanglaite injection is an extract from Coix lacryma-jobi seed and is usually combined with other agents to treat cancer. The aim of this study was to investigate the treatment effect of Taxol combined with Kanglaite on colorectal cancer cell lines. Kanglaite pretreatment followed by Taxol treatment was found to show the best synergism among all combination strategies. This combination also resulted in the smallest tumour volume in a Balb/c mice model. Kanglaite inhibited the expression of nuclear factor (NF)-κΒ and upregulated that of connexin 43, both of which sensitized cancer cells to Taxol. Moreover, Kanglaite increased many cellular variations caused by Taxol, including tubulin polymerization, caspase-3 cleavage, and upregulated expression of survivin and cyclin B1. These results suggest that Kanglaite pretreatment may increase the effect of Taxol on colorectal cancer.

A multicenter randomized controlled open-label trial to assess the efficacy of compound kushen injection in combination with single-agent chemotherapy in treatment of elderly patients with advanced non-small cell lung cancer: study protocol for a randomized controlled trial

Background

With the aging of the global population, an increasing number of elderly are diagnosed with advanced non-small cell lung cancer. Although systematic chemotherapy has been one of the primary treatments for advanced non-small cell lung cancer worldwide, the elderly cannot always tolerate standard platinum-based doublet chemotherapy, thus resulting in treatment failure. To reduce toxicity, single-agent chemotherapy is often used to treat the elderly with non-small cell lung cancer; however, this may increase the risk of treatment failure due to an inadequate dose. It has been shown that compound kushen injection in combination with chemotherapy can enhance the efficacy and reduce the toxicity. The aim of this trial is to assess the clinical effectiveness and safety of compound kushen injection in combination with single-agent chemotherapy versus platinum-based doublet chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer.

Methods

This multicenter study will be an open-label, randomized controlled trial. Three hundred seventy elderly patients with advanced non-small cell lung cancer will be randomly divided into experimental (n = 185) and control groups (n = 185) to receive compound kushen injection in combination with single-agent chemotherapy or standard platinum-based doublet chemotherapy for two cycles. After two cycles, the disease control rate, objective response rate, clinical symptoms, quality of life, Karnofsky Performance Status, and side effects will be assessed. Follow-up evaluations will be performed every 8 weeks to evaluate the progression-free and overall survival.

Discussion

Before the trial was designed, compound kushen injection was shown to be effective for lung cancer through basic experiments and clinical trials. This study will determine whether or not the efficacy of compound kushen injection in combination with single-agent chemotherapy is comparable to that of platinum-based doublet chemotherapy, and whether or not the toxicity of compound kushen injection in combination with single-agent chemotherapy is lower than that of platinum-based doublet chemotherapy.

The advantages of using traditional Chinese medicine as an adjunctive therapy in the whole course of cancer treatment instead of only terminal stage of cancer

Recent studies indicate that Traditional Chinese medicine (TCM) can play an important role in the whole course of cancer treatment such as recovery stages of post-operative, radiotherapy or chemotherapy stages instead of only terminal stage of cancer. In this review, we have summarized current evidence for using TCM as adjuvant cancer treatment in different stages of cancer lesions. Some TCMs (e.g., TJ-41, Liu-jun-zi-tang, PHY906, Coumarin, and Aescine) are capable of improving the post-operative symptoms such as fatigue, pain, appetite, diarrhea, nausea, vomiting, and lymphedema. Some TCMs (e.g., Ginseng, Huang-Qi, BanZhiLian, TJ-48, Huachansu injection, Shenqi fuzheng injection, and Kanglaite injection) in combination with chemo- or radio-therapy are capable of enhancing the efficacy of and diminishing the side effects and complications caused by chemo- and radiotherapy. Taken together, they have great advantages in terms of suppressing tumor progression, relieving surgery complications, increasing the sensitivity of chemo- and radio- therapeutics, improving an organism's immune system function, and lessening the damage caused by surgery, chemo- or radio-therapeutics. They have significant effects on relieving breast cancer-related lymphedema, reducing cancer-related fatigue and pain, improving radiation pneumonitis and gastrointestinal side effects, protecting liver function, and even ameliorating bone marrow suppression. This review of those medicines should contribute to an understanding of Chinese herbal medicines as an adjunctive therapy in the whole course of cancer treatment instead of only terminal stage of cancer, by providing useful information for development of more effective anti-cancer drugs and making more patients "survival with cancer" for a long time.

Review on the Applications and Molecular Mechanisms of Xihuang Pill in Tumor Treatment

Xihuang pill (XH) is a complementary and alternative medicine that has been used in traditional Chinese medicine (TCM) for the treatment of tumors since the 18th century. XH has clinical effects on non-Hodgkin lymphoma, breast cancer, gastric cancer, liver cancer, and bone metastasis. XH can also inhibit the growth of tumor cells and cancer stem cells, prevent tumor invasion and angiogenesis, and regulate the tumor microenvironment. XH is composed of Ru Xiang (olibanum), Mo Yao (Commiphora myrrha), She Xiang (Moschus), and Niu Huang (Calculus bovis). Some of the compounds found in these ingredients exert multiple antitumor effects and may synergize with the other ingredients. We aimed to summarize the clinical applications and molecular mechanisms of XH and its chemical composition. This review will provide potential new strategies and alternative perspectives for tumor treatments and basic research into complementary and alternative medicine.
