Can Aidi injection restore cellular immunity and improve clinical efficacy in non-small-cell lung cancer patients treated with platinum-based chemotherapy? A meta-analysis of 17 randomized controlled trials following the PRISMA guidelines

Cell Metabolomics Study on Synergistic anti-Hepatocellular Carcinoma Effect of Aidi Injection Combined with Doxorubicin

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the second most common cause of cancer deaths. This study aimed to explore the inhibitory effect and mechanism of Aidi injection (ADI) combined with doxorubicin (DOX) in HCC treatment. The drug concentrations in combined threapy was determined by investigating the effect of various concentrations of ADI and DOX on the viability of H22 cells. The combination index (CI) was also calculated. A metabolomic strategy based on ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) platform was established to analyze the metabolites. As a result, the CI values were less than 1, indicating that the combination of ADI and DOX exerted a synergistic effect on HCC treatment. The combination of 40‰ ADI and 1 μmol/L DOX had the strongest inhibitory effect and was used for subsequent metabolomic analysis. A total of 19 metabolic markers were obtained in metabolomic analysis, including amino acids (L-glutamic acid, L-arginine, and L-tyrosine), organic acids (succinic acid and citric acid), adenosine, and hypoxanthine , etc. Compared with the treatment using DOX or ADI alone, the combined therapy further regulated the levels of metabolic markers in HCC, which may be the reason for the synergistic effect. Seven metabolic pathways were significantly enriched, including phenylalanine, tyrosine and tryptophan biosynthesis, D-glutamine and D-glutamate metabolism, alanine, aspartate and glutamate metabolism, phenylalanine metabolism, arginine biosynthesis, tricarboxylic acid (TCA) cycle, and purine metabolism. These findings demonstrated that ADI combined with DOX can effectively inhibit the viability of H22 cells, which may exert a synergistic anti-tumor effect by balancing the metabolism of amino acids and energy-related substances.

Chinese patent medicine Aidi injection for cancer care: An overview of systematic reviews and meta-analyses

ETHNOPHARMACOLOGICAL RELEVANCE

Aidi injection is one of the China Food and Drug Administration approved Chinese herbal injections and the most competitive product in cancer care in China. It is composed of the extracts from Mylabris Phalerata, Astragalus Membranaceus, Panax Ginseng, and Acanthopanax Senticosus.

AIM OF THE STUDY

This overview aims to map systematic reviews (SRs) of Aidi injection for cancer and provide a summarized evidence for clinical practice and decision making.

MATERIALS AND METHODS

Seven databases were searched for SRs and/or meta-analyses of randomized controlled trials on Aidi injection for cancer care until December 2020. Six authors worked in pairs independently identified studies, collected data, and assessed the quality of included studies according to the revised Assessment of Multiple Systematic Reviews (AMSTAR 2) and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A narrative synthesis was used for the evidence mapping.

RESULTS

Fifty-two SRs on Aidi injection as adjuvant therapy were included, involving lung cancer (20 SRs), liver cancer (10), colorectal cancer (7), gastric cancer (6), lymphoma (2), breast cancer (2), esophageal cancer (1), ovary cancer (1), and a mix of different cancers (4). Except for one SR focusing on Aidi injection used alone, other SRs evaluated Aidi injection in combination with chemotherapy (43), radiotherapy (4), or chemo/radiology/targeting therapy (4). Aidi injection showed additional beneficial effects on survival (9), objective response rate (44), quality of life (42), and the reduction of side-effects from chemo/radiotherapy (48). Using AMSTAR 2 tool, two reviews were assessed as low and the rest as critically low methodological quality mainly due to the lack of prospective registration. The reporting quality was insufficient assessed with PRISMA in the reporting of search strategy (26, 50.0%), additional analysis (19, 36.5%), and the summary of evidence (2, 3.8%).

CONCLUSION

Aidi injection has been evaluated for its adjuvant beneficial effects on cancer survival, tumor responses, quality of life, and reducing the side effects of chemo/radiotherapy, mainly focusing on lung, liver and colorectal cancer. The methodological and reporting quality are weak and need to be improved in the future.

Aidi injection as adjunctive treatment to gemcitabine-based chemotherapy for advanced non-small cell lung cancer: a systematic review and meta-analysis

CONTEXT

Aidi injection is one of the most commonly use antitumor Chinese medicine injections for advanced non-small cell lung cancer (NSCLC). It is made from the extraction of Astragalus, Eleutherococcus senticosus, Ginseng, and Cantharis.

OBJECTIVE

To evaluate the efficacy and safety of Aidi injection in combination with gemcitabine-based chemotherapy (GBC) for advanced NSCLC.

MATERIALS AND METHODS

PubMed, Embase, Cochrane Library, Chinese Biological Medicine, China National Knowledge Infrastructure, Wanfang, and VIP were searched for relevant randomised controlled trials (RCTs) comparing Aidi injection plus GBC treatment with GBC alone in NSCLC, from inception up to October 2020. The primary outcomes were objective response rate (ORR), and disease control rate (DCR). Secondary outcomes were quality of life (QOL) and adverse drug reactions (ADRs). The quality of evidence was rated using the GRADE approach. This study was registered with PROSPERO: CRD42021221225.

RESULTS

In total, 54 RCTs involving 4318 NSCLC patients were included in this meta-analysis. Compared with GBC alone, Aidi injection plus GBC significantly improve ORR (risk ratios [RR] = 1.38, 95% confidence interval [CI] 1.29-1.48), DCR (RR = 1.15, 95% CI 1.12-1.19), QOL (RR = 1.71, 95% CI 1.54-1.89), and reduced the risk of gastrointestinal toxicity, thrombocytopenia, neutropenia, liver injury, renal injury, and anaemia. The evaluation results of the evidence ranged from moderate to low.

CONCLUSIONS

Current moderate evidence revealed that Aidi injection as an adjunctive treatment to GBC was associated with superior benefits in patients with advanced NSCLC and alleviate toxicities. High-quality RCTs are needed to further confirm the results.

Intrapleural Administration With Rh-Endostatin and Chemical Irritants in the Control of Malignant Pleural Effusion: A Systematic Review and Meta-Analysis

INTRODUCTION

A modified and recombinant human endostatin (Rh-endostatin) is often used in the control of malignant pleural effusion (MPE) through intrapleural infusion.

OBJECTIVES

To demonstrate the clinical response, survival, and safety of Rh-endostatin plus chemical irritants, their optimal combinations, treatment threshold, and optimal usage, we performed a new systematic review and meta-analysis.

METHODOLOGY

All randomized controlled trials (RCTs) were collected from Chinese and English electronic databases (from inception until August 2020). We pooled the data using a series of meta-analyses and summarized the evidence quality following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

We included 75 RCTs recruiting 4,678 patients, which reported six combinations for Rh-endostatin plus chemical irritants. Among the six combinations, only Rh-endostatin plus cisplatin (DDP) with enough trials might improve the complete response [2.29 (1.93, 2.71)] and quality of life [3.01 (2.49, 3.63)] and reduce treatment failure [0.29 (0.25, 0.33)] and progressive disease [0.27 (0.22, 0.34)]. It might not increase the risk of adverse drug reactions. For patients with lung cancer, moderate to massive effusion, initial treatment, Karnofsky Performance Status (KPS) score ≥60, or anticipated survival time ≥3 months, Rh-endostatin (30-45 mg each time, once or twice a week 3-4 times) plus DDP (30-60 mg/m2) obtained a significant improvement in clinical response and a reduction of failure and progressive disease. Most results had good robustness and moderate quality.

CONCLUSIONS

Current evidence suggests that Rh-endostatin with DDP may be an optimal combination, which may improve clinical response and reduce failure and progressive disease with good safety. Rh-endostatin (30-40 mg each time, once or twice a week 3-4 times) with DDP (30-40 mg/m2) may be an optimal usage for achieving an ideal response.

Aidi injection combined with chemotherapy in the treatment of cancer patients: a systematic review of systematic reviews and meta-analyses

The objective of the study was to evaluate and summarize the evidence from systematic reviews and meta-analyses regarding the efficacy and safety of Aidi injection combined with chemotherapy in the treatment of cancer patients. PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chong qing VIP databases, and Wanfang databases were searched for systematic reviews/meta-analyses on the topic of Aidi treating cancer patients published from inception to 20 December 2020. Google Scholar and OpenGrey were searched for grey literature and International Prospective Register of Systematic Reviews for ongoing reviews. Two investigators independently selected eligible studies, extracted data, and assessed the methodological quality of included systematic reviews/meta-analyses using the measurement tool to assess systematic reviews 2 (AMSTAR-2) tool, and the strength of evidence was assessed with the grade of recommendation, assessment, development, and evaluation (GRADE) system. Twenty-seven systematic reviews/meta-analyses were identified in the study. The methodological quality of all 27 systematic reviews/meta-analyses were critically low when evaluated by AMSTAR-2, and the evidence quality of all outcomes rated as either low or very low based on the GRADE system. The available evidence is currently insufficient to support or refute the use of Aidi in the treatment of cancer patients, thus high-quality trials with large sample sizes are needed to explore its efficacy and safety in cancer patients.

The Optimal Adjuvant Strategy of Aidi Injection With Gemcitabine and Cisplatin in Advanced Non-small Cell Lung Cancer: A Meta-analysis of 70 Randomized Controlled Trials

Introduction: Aidi injection (Aidi) is composed of cantharidin, astragaloside, ginsenoside, and elentheroside E. As an important adjuvant therapy, Aidi in combination with gemcitabine and cisplatin (GP) is often used in the treatment of non-small cell lung cancer (NSCLC). Objectives: We performed a new evaluation to demonstrate the clinical efficacy and safety of the Aidi and GP combination and further explored an optimal strategy for achieving an ideal response and safety level in advanced NSCLC. Methodology: We collected all the related trials from Chinese and English-language databases, analyzed their methodological bias risk using the Cochrane evaluation Handbook for Systematic Reviews of Interventions Version 5.1.0, extracted all the data using a predefined data extraction form, pooled the data using a series of meta-analyses, and finally summarized the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results: We included 70 trials with 5,509 patients. Compared with GP alone, the Aidi and GP combination showed a significant improvement in the objective response rate (ORR) [1.82 (1.62-2.04)], disease control rate (DCR) [2.29 (1.97-2.67)], and quality of life (QOL) [3.03 (2.55-3.60)] and a low incidence of hematotoxicity and gastrointestinal and hepatorenal toxicity. Aidi might be more suitable for patients who are first-treated, elderly, or patients with a Karnofsky Performance Status (KPS) score ≥ 60 or anticipated survival time (AST) ≥3 months. An Aidi (50 ml/day, 7-14 days/cycle for one to two cycles), gemcitabine (1000 mg/m2), and cisplatin (20-30 mg/m2, 40-50 mg/m2, or 60-80 mg/m2) might be an optimal regimen for realizing an ideal response and safety level. Most results were robust and of moderate quality. Conclusion: Current evidence indicates that Aidi's value in adjuvant chemotherapy may be broad-spectrum, not just for some regimens. The Aidi and GP combination may show a good short-term response, antitumor immunity, and safety level in patients with NSCLC. Aidi (50 ml/day, 7-14 days/cycle for one and two cycles) with GEM (1000 mg/m2) and DDP (20-30 mg/m2 or 40-50 mg/m2) may be an optimal regimen for realizing an ideal goal in patients who are first-treatment, elderly, or have a KPS score ≥ 60 or AST≥3 months.

Aidi injection, a traditional Chinese biomedical preparation for gynecologic tumors: a systematic review and PRISMA-compliant meta-analysis

Aidi injection (ADI), a traditional Chinese biomedical preparation, is a promising adjuvant therapy for gynecologic tumors (GTs), including cervical cancer (CC), endometrial cancer (EC), and ovarian cancer (OC). Although studies have reported positively on ADI therapy, its exact effects and safety in GT patients remain controversial. Therefore, a wide-ranging systematic search of electronic databases was performed for this meta-analysis. Data from 38 trials including 3309 GT patients were analyzed. The results indicated that the combination of conventional treatment and ADI markedly improved the patients’ overall response rate (P<0.00001), disease control rate (P<0.00001), and quality of life (P<0.05) compared with conventional treatment alone. Furthermore, patient immunity was enhanced with combined treatment, as indicated by significantly increased percentages of CD3⁺ (P=0.005) and CD4⁺ (P<0.00001) and increased CD4⁺/CD8⁺ ratio (P=0.001). Most of the adverse events caused by radiochemotherapy such as gastrointestinal issues, leukopenia, thrombocytopenia, and hepatotoxicity, (P<0.05 for all) were significantly alleviated when ADI was used in the GT patients. However, other adverse events such as nephrotoxicity, diarrhea, alopecia, and neurotoxicity did not significantly differ between the two groups. Overall, these results suggest that the combination of conventional and ADI treatment is more effective than conventional treatment alone.

Investigation on the Efficiency of Chinese Herbal Injections for Treating Non-small Cell Lung Cancer With Vinorelbine and Cisplatin Based on Multidimensional Bayesian Network Meta-Analysis

Background: As non-small cell lung cancer (NSCLC) seriously threatens human health, several clinical studies have reported that Chinese herbal injections (CHIs) combined with vinorelbine and cisplatin (NP) are beneficial. This multidimensional network meta-analysis was performed to explore the preferable options among different CHIs for treating NSCLC.

Methods: A literature search was performed in several databases to identify randomized controlled trials (RCTs) of CHIs in the treatment of NSCLC from inception to January 31, 2019. Final included studies met the eligibility criteria and methodological quality recommendations. Data analysis was performed using Stata 13.0 and WinBUGS 14.0 software. Each outcome was presented as an odds ratio and the surface under the cumulative ranking curve value (SCURA). The “scatterplot3d” package in R 3.6.1 software was used to perform multidimensional cluster analysis.

Results: Ultimately, 97 eligible RCTs involving 7,440 patients and 14 CHIs were included in this network meta-analysis. Combined with NP chemotherapy, Kanglaite injection plus NP exhibited a better impact on the clinical effectiveness rate (SCURA probability: 78.34%), and Javanica oil emulsion injection plus NP was better in the performance status (95.44%). Huachansu injection plus NP was dominant in reducing thrombocytopenia (92.67%) and gastrointestinal reactions (92.52%). As to multidimensional cluster analysis, Shenmai injection plus NP was superior considering improving the clinical effectiveness rate, performance status and relieving leukopenia.

Conclusions: The combination of CHIs and NP has a better impact on patients with NSCLC than NP alone. Among them, Shenmai injection plus NP, Kanglaite injection plus NP and Javanica oil emulsion injection plus NP were notable. Nevertheless, more multicenter and better designed RCTs are needed to validate our findings.

Meta-Analysis of Aidi Injection and First-Generation Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitor Therapy in Treating Advanced Non-Small Cell Lung Cancer

The combination of Aidi injection (ADI) and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in treating non-small cell lung cancer (NSCLC) has been reported, but the effects of this therapy have not been systematically assessed. Randomized controlled trials (RCTs) published before June 2020 were searched from 6 databases. Two reviewers independently assessed the methodological quality of 8 RCTs involving 667 patients diagnosed with stage III-IV NSCLC. We found that ADI combined with EGFR-TKI increased the objective response rate (ORR) significantly (relative risk [RR]: 1.60; 95% confidence interval [CI]: 1.28-1.99, P < 0.0001). There was also improvement in the disease control rate (DCR) (RR: 1.25; 95% CI: 1.11-1.40, P = 0.0002) as compared with EGFR-TKI alone. This therapy also increased the percentage of CD3+ cells (weighted mean difference [WMD]: 9.86; 95% CI: 4.62-15.10), CD4+ cells (WMD: 6.10; 95% CI: 1.67-10.53), and the CD4+/CD8+ (WMD: 0.35; 95% CI: 0.28-0.43). With regard to drug toxicity, the occurrence of rash was significantly reduced by ADI combined with EGFR-TKI (RR: 0.78, 95% CI: 0.63-0.97, P = 0.03); however, we did not find a significant reduction in the occurrence of dry skin, nausea and vomiting, as well as diarrhea between the 2 therapies. ADI combined with first-generation EGFR-TKIs may be more effective in improving tumor response, reducing the occurrence of rash, and enhancing immune function in NSCLC than EGFR-TKI alone.

Clinical application and mechanism of traditional Chinese medicine in treatment of lung cancer

Lung cancer is a malignant tumor characterized by a rapid proliferation rate, less survivability, high mortality, and metastatic potential. This review focuses on updated research about the clinical application of traditional Chinese medicine (TCM) as an adjuvant therapy to lung cancer treatment and the mechanisms of TCM effect on lung cancer in vitro and in vivo. We summarized the recent 5 years of different research progress on clinical applications and antitumor mechanisms of TCM in the treatment of lung cancer. As a potent adjuvant therapy, TCM could enhance conventional treatments (chemotherapy, radiation therapy, and epidermal growth factor receptors [EGFRs] tyrosine kinase inhibitors [TKIs]) effects as well as provide synergistic effects, enhance chemotherapy drugs chemosensitivity, reverse drug resistance, reduce adverse reactions and toxicity, relieve patients’ pain and improve quality of life (QOL). After treating with TCM, lung cancer cells will induce apoptosis and/or autophagy, suppress metastasis, impact immune reaction, and therapeutic effect of EGFR-TKIs. Therefore, TCM is a promisingly potent adjuvant therapy in the treatment of lung cancer and its multiple mechanisms are worthy of an in-depth study.

Clinical efficacy and safety of aidi injection combination with vinorelbine and cisplatin for advanced non-small-cell lung carcinoma: A systematic review and meta-analysis of 54 randomized controlled trials

The Aidi injection contains multiple active ingredients, including astragaloside (Re, Rb1, and Rg1), ginsenoside, cantharidin, elentheroside E, and syringin, and it is administered with vinorelbine and cisplatin (NP) to treat non-small-cell lung carcinoma (NSCLC). In this study, we performed a systematic review and meta-analysis to determine the clinical efficacy and safety of the Aidi injection with NP, and the optimal threshold and treatment regimen to produce the desired responses. We collected all studies regarding the Aidi injection with NP for NSCLC from Chinese and English databases (up to April 2019). Risk of methodological bias was evaluated for each study. Data for analysis were extracted using a standard data extraction form. Evidence quality was assessed following the Grading of Recommendations Assessment, Development and Evaluation approach. We included 54 trials containing 4,053 patients for analysis. Combining the Aidi injection with NP significantly increased the objective response rate (odds ratio [OR], 1.32; confidence interval [CI], 1.23, 1.42), disease control rate (OR, 1.14; CI, 1.11, 1.18), and quality of life (OR, 1.80; CI, 1.61, 1.98), with decreased risks of myelosuppression, neutropenia, thrombocytopenia, anemia, gastrointestinal reaction, and liver dysfunction. For patients with a Karnofsky Performance Status score of ≥60, the Aidi injection (50 mL/day, two weeks/cycle, with two to three cycles) treatment with vinorelbine (25 mg/m²) and cisplatin (30-35 mg/m² or 40-50 mg/m²) might be the optimal regimen for producing the desired tumor response and achieving a good safety level. Most results were robust, and their quality was moderate. The results suggest that administration of the Aidi injection and concomitant NP is beneficial to NSCLC, and provide evidence for the optimal threshold and treatment regimen that may improve tumor response with a good safety level.

Integrative cancer treatment may have a survival benefit in patients with lung cancer: A retrospective cohort study from an integrative cancer center in Korea

Integrative oncology is being increasingly adopted in mainstream cancer care to strengthen anticancer effects and to control cancer-related symptoms.The objective of this study is to identify the characteristics of patients with lung cancer treated at an integrative cancer center in Korea and to determine the effects of integrative cancer treatment (ICT) on survival outcome in traditional Korean medicine (TKM).We reviewed medical records for lung cancer patients who visited a single integrative clinical setting, East-West Cancer Center, between January 2014 and December 2015. We classified the patients into groups according to their ICT and whether or not they underwent anticancer traditional Korean Medicine treatment with a multiherbal formula containing Panax notoginseng Radix, Cordyceps militaris, P ginseng C.A.Mey., and Boswellia carterii BIRDWOOD (HangAmDan-B), with a herbal formula containing Rhus verniciflua Stoke, or with cultivated wild ginseng pharmacopuncture. A descriptive analysis of the characteristics and a survival analysis using the Kaplan-Meier curves with log rank test and a Cox proportional hazard model were performed.A total of 91 patients were included, and the majority had advanced-stage cancer. Of those patients, 45.1% were in the mono-TKM group and 39.6% were integrative group. Patients with advanced stage had significantly higher mortality than patients with early stage (crude hazard ratio [HR]: 4.41, 95% confidence interval [CI]: 1.56-12.5; adjusted HR: 6.31, 95% CI: 1.24-32.1). In the unadjusted model, for patients in the integrative group, the mortality rate was reduced by 50% compared to mono-TKM group with statistical significance. After adjusting confounders, the mortality rate of integrative group was reduced by 6% compared to mono-TKM group, suggesting positive effect on survival probability of integrative group.The results suggest that integration of TKM and conventional cancer treatment may have survival benefits in patients with lung cancer. Even though this study has limitations including heterogeneity between treatment groups, the study results suggest that ICT has positive effect on survival probability. To clarify the impacts of ICT for lung cancer and other cancers on survival outcome, further prospective study with a rigorous study design is required in multiclinical setting.

Evidence of Astragalus injection combined platinum-based chemotherapy in advanced nonsmall cell lung cancer patients: A systematic review and meta-analysis

BACKGROUND

Platinum-based chemotherapy is one of the standard treatments for advanced nonsmall cell lung cancer (NSCLC). Despite on an effective treatment for advanced NSCLC patients, its high toxicity and limited clinical effects have raised big concerns. Astragalus injection (AGI) has been commonly employed as an adjutant chemotherapy drug for NSCLC in China. This review was conducted to evaluate the beneficial of AGI in combination with platinum-based chemotherapy in advanced NSCLC.

METHODS

We collected all studies about AGI plus platinum-based chemotherapy for advanced NSCLC in the PubMed, EMBASE, China National Knowledge Infrastructure Database, the Cochrane Library, Wanfang Database, China Biological Medicine Database, and Chinese Scientific Journal Database established on July 2018 without language restriction. Cochrane handbook was applied to assess the quality of included trials. Stata (version 12.0) and RevMan (version 5.3) were employed for data analysis. The quality of the evidence was assessed with the GRADE approach.

RESULTS

Nineteen randomized controlled trials (RCTs) including 1635 patients were included to determine the effectiveness and safety of AGI combined with platinum-based chemotherapy in the treatment of NSCLC. The result of meta-analysis indicated that comparing with chemotherapy alone, AGI combined chemotherapy could significantly improve the objective response rate (relative risk [RR] = 1.19, 95% confidence interval [CI] [1.06, 1.33], P = .002), the Karnofsky performance status (RR = 2.28, 95% CI [1.63, 3.18], P < .00001), and 1-year survival rate (RR = 1.40, 95% CI [1.16, 1.70], P = .0005), meanwhile increase the percentages of CD3 (weighted mean differences [WMD] = 11.98, 95% CI [8.0, 15.96], P < .00001), CD4 (WMD = 2.98, 95% CI [0.45, 5.52], P = .02), CD4/CD8 (WMD = 0.33, 95% CI [0.20, 0.46], P < .00001), and NK cells (WMD = 9.5, 95% CI [7.25, 11.76], P < .00001), decrease the incidence of leukopenia (RR = 0.52, 95% CI [0.44, 0.61], P < .00001), platelet toxicity (RR = 0.62, 95% CI [0.50, 0.76], P < .00001), and vomiting (RR = 0.72, 95% CI [0.60, 0.87], P = .0006). Based on the system evaluation results, the GRADE system recommendation grading method was adopted to evaluate the evidence quality. The results showed that the level of evidence was low.

CONCLUSIONS

The AGI apparently has attenuation and synergistic efficacy to platinum-based chemotherapy patients. However, considering the limits of articles included in the present researches, the recommendation is likely to be weak. High-quality RCTs are urgently used to generate conclusive results.

Clinical efficacy and safety of Aidi injection plus paclitaxel-based chemotherapy for advanced non-small cell lung cancer: A meta-analysis of 31 randomized controlled trials following the PRISMA guidelines

ETHNOPHARMACOLOGICAL RELEVANCE

As an important Chinese herb injection, Aidi injection is composed of the extracts from Astragalus, Eleutherococcus senticosus, Ginseng, and Cantharis. Aidi injection plus paclitaxel-based chemotherapy is often used to in the treatment of non-small cell lung cancer (NSCLC) in China.

AIM OF THE STUDY

The objective of this study is to further confirm whether Aidi injection can improve the tumor responses and survivals, and reveal its safety, optimal usage and combination with paclitaxel.

MATERIALS AND METHODS

A meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All randomized controlled trials (RCTs) concerning the Aidi injection plus paclitaxel-based chemotherapy for NSCLC were selected. Main outcomes were objective response rate (ORR), disease control rate (DCR), survivals, quality of life (QOL) and adverse drug reactions (ADRs). All data were extracted by using a standard data extraction form and synthesized through meta-analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used for rating the quality of evidence.

RESULTS

Thirty-one RCTs involving 2058 patients were included, and most trials had an unclear methodological bias risk. The risk ratio (RR) and 95% confidence intervals (CI) of ORR, DCR, QOL, neutropenia, thrombocytopenia, gastrointestinal toxicity and liver injury were as following: 1.32 (1.20-1.46), 1.14 (1.09-1.20), 1.89 (1.66-2.16), 0.61 (0.51-0.74), 0.62 (0.45-0.87), 0.59 (0.49-0.72) and 0.52 (0.36-0.75). Compared to chemotherapy alone, all differences were statistically significant. Subgroup analysis showed that only with the TP, Aidi injection could increase the ORR and DCR. Treatment with 100 ml, 80 ml or 50 ml/time, and 14 days/2 cycles or 21 days/2-4 cycles, Aidi injection could increase the ORR and DCR, respectively. Sensitivity analysis showed that the results had good robustness. None of the trials reported the overall survivals (OS), progression free survival (PFS). The quality of evidences was moderate.

CONCLUSIONS

Current moderate evidence revealed that Aidi injection plus paclitaxel-based chemotherapy, especially TP can significantly improve the clinical efficacy and QOL for patients with stage III/IV NSCLC. Aidi injection can relieve the risk of hematotoxicity, gastrointestinal toxicity and liver injury in patient with NSCLC receiving paclitaxel-based chemotherapy. The optimal usage may be 50 ml/time and 14 days/2 cycles.

Aidi Injection, a Traditional Chinese Medicine Injection, Could Be Used as an Adjuvant Drug to Improve Quality of Life of Cancer Patients Receiving Chemotherapy: A Propensity Score Matching Analysis

Background: Clinical research has paid increasing attention to quality of life (QoL) in recent years, but the assessment of QoL is difficult, hampered by the subjectivity, complexity, and adherence of patients and physicians. According to previous studies, QoL in cancer patients is related to performance status (PS) and influenced by chemotherapy-related toxicity. Aidi injection, a traditional Chinese medicine injection, is used as an adjuvant drug to enhance effectiveness of chemotherapy. The study aims to investigate whether Aidi injection could improve QoL by improving PS and reducing toxicity caused by chemotherapy. Methods: A retrospective cohort study was performed at the First Affiliated Hospital of Anhui Medicine University. Data of consecutive patients diagnosed with cancers between January 2014 and June 2017 were retrieved from the electronic medical record system. After a 1:1 propensity score match, patients were then divided into 2 groups based on the therapies used, that is, Aidi injection combined with chemotherapy and chemotherapy alone, and the PS, chemotherapy-related toxicity, and combined medication information were compared. The effect of different dosages of Aidi injection on patients was further explored. Results: A total of 3200 patients were included in this study. Aidi injection combined with chemotherapy exhibited significantly benefit in PS (P < .001, odds ratio [OR] 3.4, 95% confidence interval [CI] 2.4-4.8) compared with chemotherapy alone after adjusting for the factors that affect PS. The improvement rate of PS in the Aidi group was significantly higher than in the control group across the stratification of gender, age, tumor type, TNM stage, body mass index, nodal metastasis, prior chemotherapy, chemotherapy regimens, other Chinese tradition medicines, and chemotherapy cycle. Meanwhile, Aidi injection used synchronously with chemotherapeutic drugs could decrease the incident rate of damage to liver and kidney function, myelosuppression, and gastrointestinal reactions caused by chemotherapy. Conclusion: It was indicated that the integrative approach combining chemotherapy with Aidi injection, especially with the conventional dosage of Aidi injection, had significant benefit on QoL in cancer patients.

Clinical efficacy and safety of sodium cantharidinate plus chemotherapy in non-small-cell lung cancer: A systematic review and meta-analysis of 38 randomized controlled trials

WHAT IS KNOWN AND OBJECTIVE

Sodium cantharidinate has been widely used in lung cancer treatment in China. To investigate whether sodium cantharidinate improves clinical effectiveness in non-small-cell lung cancer, we systematically re-evaluated all related studies.

METHODS

All studies of cantharidinate for non-small-cell lung cancers (NSCLC) were selected from the MEDLINE, EMBASE, Web of Science (ISI), China National Knowledge Infrastructure Database (CNKI), Chinese Scientific Journals Full-Text Database (VIP), Wanfang, China Biological Medicine Database (CBM), Cochrane Central Register of Controlled Trials (CENTRAL), Chinese clinical trial registry (Chi-CTR), WHO International Clinical Trials Registry Platform (WHO-ICTRP) and US-clinical trials databases (established to September 2017). Their quality was evaluated using the Cochrane evaluation handbook of randomized controlled trials (RCTs) (5.1.0). The data were extracted following PICO principles and synthesized through meta-analysis.

RESULTS AND DISCUSSION

We included 38 trials involving 2845 patients, but most trials had an unclear risk of bias. Sodium cantharidinate could increase the objective response rate (ORR) (1.52, (1.40-1.66]), disease control rate (DCR) (1.20, [1.16-1.25]) and quality of life (QOL) (1.76, [1.56-1.98]), but not the 1-year overall survival (OS) rate (1.16, [0.91-1.47]) and the 2-year OS rate (1.21, [0.51-2.91]). Subgroup analysis revealed that sodium cantharidinate and vitamin B6 at 0.5, 0.4 or 0.3 mg, and cantharidinate at 0.5 mg could all increase the ORR and DCR. Cantharidinate therapy had a lower risk of neutropenia (0.58, [0.50-0.67]), thrombocytopenia (0.57, [0.45-0.72]), gastrointestinal reaction (0.65, [0.52-0.82]) and nausea/vomiting (0.56, [0.41-0.76]) than that of chemotherapy alone. Sensitivity analysis showed that the results had good robustness.

WHAT IS NEW AND CONCLUSION

Current evidence reveals that sodium cantharidinate can improve tumour responses and QOL with a lower risk of haematotoxicity and gastrointestinal toxicity than chemotherapy alone in NSCLC. However, the evidence does not indicate that it can improve long-term survival rates.

Aidi injection plus platinum-based chemotherapy for stage IIIB/IV non-small cell lung cancer: A meta-analysis of 42 RCTs following the PRISMA guidelines

ETHNOPHARMACOLOGICAL RELEVANCE

Aidi injection is one of the most commonly used Chinese patent medicines for advanced non-small cell lung cancer (NSCLC). It is made from an extraction of Mylabris Phalerata, Radix Astragalus, Radix Ginseng, and Acanthopanax Senticosus.

AIM OF THE STUDY

The objective of this study is to evaluate the efficacy and safety of Aidi injection in combination with platinum-based chemotherapy for stage IIIB/IV NSCLC.

MATERIALS AND METHODS

A systematic review and meta-analysis were performed following the PRISMA (the Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Trials were combined using Review Manager 5.3 and Comprehensive Meta-Analysis(CMA) 2.0. Dichotomous data were expressed as risk ratio (RR) and continuous outcomes as weighted mean difference (WMD), with their 95% confidence intervals (CI) respectively. All randomized controlled trials (RCTs) comparing Aidi injection plus platinum-based chemotherapy versus platinum-based chemotherapy, with efficacy and safety outcomes were selected. Disease Control Rate (DCR) was the primary outcome, Objective Response Rate (ORR), survival rate, quality of life (QOL), and toxic effects were the secondary outcomes.

RESULTS

42 RCTs recruiting 4081 patients with stage IIIB/IV NSCLC were included, with overall low-moderate methodological quality. Compared with platinum-based chemotherapy alone, Aidi injection plus platinum-based chemotherapy can increase relative benefit of DCR (RR = 1.13, 95% CI 1.09-1.16, P < 0.00001), ORR (RR = 1.26, 95% CI 1.18-1.36, P < 0.00001), improve 1-, 2-, 3-year survival rates (RR = 1.14, 95% CI 1.02-1.28, P = 0.03; RR = 1.31, 95% CI 1.05-1.64, P = 0.02; and RR = 1.88, 95% CI 1.32-2.67, P = 0.0005, respectively), QOL (RR = 1.80, 95% CI 1.61-2.01, P < 0.00001), and reduce severe (grade 3 and 4) toxicities by 36% (RR = 0.64, 95% CI 0.58-0.70, P < 0.00001).

CONCLUSIONS

From the available evidence, compared with platinum-based chemotherapy alone, Aidi injection plus platinum-based chemotherapy improves the clinical efficacy and alleviates the toxicity of chemotherapy in patients with stage IIIB/IV NSCLC. However, considering the intrinsic limitations of the included RCTs, well-designed, rigorously performed, high-quality trials are still required to further assess and confirm the results.

Clinical Efficacy and Safety of Aidi Injection Plus Docetaxel-Based Chemotherapy in Advanced Nonsmall Cell Lung Cancer: A Meta-Analysis of 36 Randomized Controlled Trials

Background. Aidi injection is an important adjuvant anticancer drug commonly used in China. Can Aidi injection plus docetaxel-based chemotherapy improve clinical efficacy with good safety in NSCLC? To further reveal its clinical effectiveness, we systematically evaluated all the related studies. Method. We collected all the studies about Aidi injection plus docetaxel-based chemotherapy for NSCLC on Medline, Embase, Web of Science, CNKI, VIP, Wanfang, CBM, CENTRAL, Chi-CTR, and US-clinical trials. We evaluated their methodological bias risk according to the Cochrane evaluation handbook (5.1.0), extracted data following the predesigned data extraction form according to the PICO principle, and synthesized the data using meta-analysis. Results. We included 36 RCTs with 2837 patients, and most studies had unclear bias risk. The merged RR values and their 95% CI of meta-analysis for ORR, DCR, and QOL were as follows: 1.30 (1.19, 1.42), 1.17, (1.12, 1.22), and 1.73 (1.54, 1.95). The merged RR values for neutropenia, thrombocytopenia, anemia, gastrointestinal toxicity, hepatorenal dysfunctions, and alopecia were as follows: 0.70 (0.61, 0.79), 0.63 (0.53, 0.75), 0.60 (0.48, 0.75), 0.76 (0.65, 0.89), 0.56 (0.36, 0.88), and 0.58 (0.36, 0.93). Compared with chemotherapy alone, all differences were statistically significant. Subgroup analysis showed that, with 100 ml, 80-100 ml, and 50 ml, Aidi injection could increase the tumor response and Aidi injection plus DP, DC, and DO could increase the tumor response. Meta-analysis results had good stability. Conclusions. Aidi injection plus docetaxel-based chemotherapy, especially plus DP, DC, and DO, may significantly improve the clinical efficacy and QOL in NSCLC. It may also have low risk of hematotoxicity, gastrointestinal toxicity, and low risk of inducing hepatorenal dysfunctions. Aidi injection may have attenuation and synergistic efficacy to docetaxel chemotherapy. All these need to have new evidence to be proved.
