Intrapleural Perfusion With Staphylococcal Enterotoxin C for Malignant Pleural Effusion: A Clustered Systematic Review and Meta-Analysis.

ABSTRACT:

Introduction

The staphylococcal enterotoxin C (SEC), a commercially available bio-product from Staphylococcus aureus (S. aureus), has been widely used to control MPE.

Objectives

We designed and performed a new systematic review (SR) and meta-analysis to clarify the perfusion protocols with SEC, determine their clinical effectiveness and safety, and reveal the indication and optimum usage for achieving the desired responses.

Methodology

All randomized controlled trials (RCTs) about SEC for MPE were collected from electronic databases (from inception until July 2021), and clustered into multiple logical topics. After evaluating their methodological quality, we pooled the data from each topic using the meta-analysis or descriptive analysis, and summarized the evidence quality using the grading of recommendation assessment, development, and evaluation (GRADE) approach.

Results

All 114 studies were clustered into SEC perfusion alone or plus chemical agents. The SEC alone showed a better complete response (CR), a lower pleurodesis failure, and adverse drug reactions (ADRs), and a higher fever than cisplatin (DDP) alone. The SEC and chemical agents developed 10 perfusion protocols. Among them, only SEC and DDP perfusion showed a better CR, a lower failure, disease progression and ADRs, and a higher fever than DDP alone. The SEC (100-200 ng per time, one time a week for one to four times) with DDP (30-40 mg, or 50-60 mg each time) significantly improved clinical responses for patients with moderate to large volume, Karnofsky performance status (KPS) scores ≥40, ≥50, or ≥60, and anticipated survival time (AST) ≥2 or 3 months. Most results were moderate to low quality.

Conclusion

Current pieces of evidence indicate that super-antigen SEC is a pleurodesis agent, which provides an attractive alternative to existing palliative modalities for patients with MPE. Among 10 protocols, the SEC and DDP perfusion is a most commonly used, which shows a significant improvement in clinical responses with low ADRs. These findings also provide a possible indication and optimal usage for SEC and DDP perfusion.

Project description:BackgroundPatients with malignant pleural effusion (MPE) are usually treated with an indwelling pleural catheter (IPC) or pleurodesis. However, most do not achieve a satisfactory control rate of pleural effusion and have poor prognosis. Distilled water has cytocidal effects of hypotonic shock and can result in the lysis of cancer cells which was used in surgery to eradicate cancer cells. However, there is no study focusing on the efficacy of intrapleural hyperthemic perfusion for MPE under video-assisted thoracoscopic surgery (VATS). This study explored the efficacy and safety of intrapleural hyperthermic perfusion (IHP) with distilled water in patients with MPE.MethodsIn this retrospective, single-arm trial, patients admitted to department of cardiothoracic surgery of Taizhou hospital and diagnosed with MPE caused by non-small cell lung cancer from January 2014 and December 2018 were included. The clinical characteristics including age, gender smoking history, Karnofsky score, volume of pleural effusion, TNM cancer stage, pathology, genetic test of patients were collected. Patients were treated with hyperthermic perfusion. The pleural cavity was perfused with 43.0 ℃ distilled water for 60 minutes under video-assisted thoracic surgery (VATS). The efficacy of treatment was defined as follows: (I) complete remission (CR; no recurrence of pleural effusion after IHP for at least four weeks); (II) partial remission (PR; pleural effusion was decreased by 50% and the condition lasted for 4 weeks; or (III) no remission (NR; no decrease in pleural effusion). Kaplan-Meier method with a log-rank test was used for survival analysis. Cox proportional hazards regression models were applied to perform univariate and multivariate analyses.ResultsFrom January 2014 through December 2018, 30 patients with MPE caused by non-small cell lung cancer (NSCLC) were treated with hyperthermic perfusion. There were no serious reportable clinical complications associated with the procedure. The response rate was 96.7%, with 63.3% experiencing PR and 33.3% achieving CR. The overall survival (OS) ranged from 2 to 46 months. The median survival was 12 months.ConclusionsIHP proved to be a feasible and safe strategy for patients with MPE in our study but it still needs to be verified with a larger, prospective and randomized trial in the future.

Project description:Objective:To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE).Methods:This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure.Results:Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: -225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676).Conclusions:Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE.Objetivo:Avaliar o papel do posicionamento intrapleural do cateter pleural na expansão pulmonar precoce e no sucesso da pleurodese em pacientes com derrame pleural maligno recorrente (DPMR).Métodos:Trata-se de um estudo retrospectivo aninhado em um estudo prospectivo de coorte maior com pacientes com DPMR recrutados em um hospital-escola universitário terciário entre junho de 2009 e setembro de 2014. Os pacientes foram submetidos a inserção de cateter pleural e, em seguida, pleurodese à beira do leito. A TC de tórax foi realizada duas vezes: imediatamente antes da pleurodese (TCi) e 30 dias após a pleurodese (TC30). Com base na TCi, a posição do cateter foi classificada em posterolateral, anterior, fissural e subpulmonar. Usamos o volume pleural na TCi para estimar a expansão pulmonar precoce e a diferença entre os volumes pleurais na TC30 e na TCi a fim de avaliar o sucesso radiológico da pleurodese. Considerou-se que a pleurodese teve êxito clínico quando não foi necessário realizar nenhum outro procedimento pleural.Resultados:Dos 131 pacientes elegíveis do estudo original, 85 foram incluídos neste estudo aninhado (64 mulheres; média de idade: 60,74 anos). A posição da ponta do cateter foi subpulmonar em 35 pacientes (41%), anterior em 23 (27%), posterolateral em 17 (20%) e fissural em 10 (12%). Não houve diferenças significativas entre os grupos quanto à expansão pulmonar precoce (mediana da cavidade pleural residual = 377 ml; intervalo interquartil: 171-722 ml; p = 0,645), sucesso radiológico da pleurodese (mediana do volume = 33 ml; intervalo interquartil: -225 a 257 ml; p = 0,923) e sucesso clínico da pleurodese (85,8%; p = 0,676).Conclusões:Nossos resultados sugerem que a posição da ponta do cateter pleural não influencia nem a expansão pulmonar precoce nem o sucesso da pleurodese à beira do leito em pacientes com DPMR.

Project description:BackgroundMalignant pleural effusion (MPE) is a common complication in patients with advanced lung cancer that can severely compromise the quality of life and limit life expectancy. Randomized controlled trials (RCTs) have shown that Chinese herbal injections (CHIs) may be beneficial in improving quality of life. This network meta-analysis (NMA) aims to explore several CHIs used for lung cancer patients with MPE.MethodsSeven databases were systematically searched for eligible RCTs from inception to November 2021. The primary outcome was the clinical effective rate. Secondary outcomes were the improvement rate of Karnofsky performance status (KPS) score and incidence of adverse events (AEs). The Cochrane risk of bias 2 tool was used to assess the quality of included studies. Data analysis was performed using STATA 16.0 and R software 4.1.0. Both pairwise meta-analysis and Bayesian NMA were conducted. Competing interventions were ranked using the surface under the cumulative ranking (SUCRA) probabilities. Evidence grading was evaluated using the Confidence in Network Meta-Analysis online software (https://cinema.ispm.unibe.ch/).ResultsA total of 44 studies involving 2,573 patients were included. The combined Huachansu injection (HCS) with intrapleural cisplatin (cis-diamminedichloro-platinum, DDP) had the highest probability of improving the clinical effective rate (SUCRA, 84.33%). The Kangai injection (KA) combined with DDP had the most improvement rate of KPS score (SUCRA, 80.82%), while the Fufangkushen injection (FFKS) alone was more likely to reduce AEs including gastrointestinal reactions (SUCRA, 89.92%), leukopenia (SUCRA, 91.85%), and chest pain (SUCRA, 98.17%). FFKS combined with DDP ranked the best in reducing the incidence of fever (SUCRA, 75.45%).ConclusionsOur NMA showed that CHIs alone or combined with DDP could improve clinical effectiveness and quality of life and reduce AEs, compared to DDP alone. HSC and KA, combined with DDP, may be the most effective considering clinical effective rate and improvement of KPS score, respectively. FFKS, either used alone or in combination therapy with DDP, may be the best in reducing AEs. However, high-quality RCTs with larger sample sizes are needed to further support the evidence.Systematic review registrationPROSPERO https://www.crd.york.ac.uk/prospero/, identifier CRD42021285275.
