Abstract
OBJECTIVE Malignant pleural effusion is a severe and common complication in patients with primary or metastatic malignancies of the pleura. Although talc pleurodesis is widely used for managing malignant pleural effusions, there is still controversy in the literature regarding its superiority compared to other approaches. We conducted this meta-analysis to further investigate its efficacy compared to alternative interventions. METHODS We systematically reviewed the PubMed, Cochrane, and Scopus databases to identify studies that fulfilled our inclusion criteria. Study quality was evaluated using validated tools and the pooled Risk Ratio (RR) and confidence interval (CI) were calculated. We performed sensitivity analyses based on the meta-analysis method and type of study. RESULTS Twenty-four studies were included in the current systematic review meta-analysis. Talc pleurodesis was associated with statistically significant higher successful pleurodesis rates when compared with all controls [RR (95% CI) 1.15 (1.00, 1.31); Pz = 0.04], only chemical controls [RR (95% CI) 1.26 (1.13, 1.40); Pz < 0.0001], and bleomycin [RR (95% CI) 1.22 (1.05, 1.42); Pz = 0.008]. The comparison between talc pleurodesis and controls at the > 1-month follow-up time point favored talc pleurodesis [RR (95% CI): 1.62 (1.15, 2.27); Pz = 0.005]. Finally, talc poudrage was associated with a statistically significant higher successful pleurodesis rate when compared with all controls. Sensitivity analyses verified the robustness of our results. CONCLUSION Talc pleurodesis is an effective MPE management approach presenting borderline statistically significant superiority compared to control methods especially compared to bleomycin as well as when pleurodesis success is evaluated later than 1 month postoperatively.

Abstract
BACKGROUND Malignant pleural effusion (MPE) is a common problem for people with cancer and usually associated with considerable breathlessness. A number of treatment options are available to manage the uncontrolled accumulation of pleural fluid, including administration of a pleurodesis agent (via a chest tube or thoracoscopy) or placement of an indwelling pleural catheter (IPC). This is an update of a review published in Issue 5, 2016, which replaced the original, published in 2004. OBJECTIVES To ascertain the optimal management strategy for adults with malignant pleural effusion in terms of pleurodesis success and to quantify differences in patient-reported outcomes and adverse effects between interventions. SEARCH METHODS We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid) and three other databases to June 2019. We screened reference lists from other relevant publications and searched trial registries. SELECTION CRITERIA We included randomised controlled trials of intrapleural interventions for adults with symptomatic MPE, comparing types of sclerosant, mode of administration and IPC use. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data on study design, characteristics, outcome measures, potential effect modifiers and risk of bias. The primary outcome was pleurodesis failure rate. Secondary outcomes were adverse events, patient-reported breathlessness control, quality of life, cost, mortality, survival, duration of inpatient stay and patient acceptability. We performed network meta-analyses of primary outcome data and secondary outcomes with enough data. We also performed pair-wise meta-analyses of direct comparison data. If we deemed interventions not jointly randomisable, or we found insufficient available data, we reported results by narrative synthesis. For the primary outcome, we performed sensitivity analyses to explore potential causes of heterogeneity and to evaluate pleurodesis agents administered via a chest tube only. We assessed the certainty of the evidence using GRADE. MAIN RESULTS We identified 80 randomised trials (18 new), including 5507 participants. We found all except three studies at high or unclear risk of bias for at least one domain. Due to the nature of the interventions, most studies were unblinded. Pleurodesis failure rate We included 55 studies of 21 interventions in the primary network meta-analysis. We estimated the rank of each intervention's effectiveness. Talc slurry (ranked 6, 95% credible interval (Cr-I) 3 to 10) is an effective pleurodesis agent (moderate certainty for comparison with placebo) and may result in fewer pleurodesis failures than bleomycin and doxycycline (bleomycin versus talc slurry: odds ratio (OR) 2.24, 95% Cr-I 1.10 to 4.68; low certainty; ranked 11, 95% Cr-I 7 to 15; doxycycline versus talc slurry: OR 2.51, 95% Cr-I 0.81 to 8.40; low certainty; ranked 12, 95% Cr-I 5 to 18). There is little evidence of a difference between the pleurodesis failure rate of talc poudrage and talc slurry (OR 0.50, 95% Cr-I 0.21 to 1.02; moderate certainty). Evidence for any difference was further reduced when restricting analysis to studies at low risk of bias (defined as maximum one high risk domain in the risk of bias assessment) (pleurodesis failure talc poudrage versus talc slurry: OR 0.78, 95% Cr-I 0.16 to 2.08). IPCs without daily drainage are probably less effective at obtaining a definitive pleurodesis (cessation of pleural fluid drainage facilitating IPC removal) than talc slurry (OR 7.60, 95% Cr-I 2.96 to 20.47; rank = 18/21, 95% Cr-I 13 to 21; moderate certainty). Daily IPC drainage or instillation of talc slurry via IPC are likely to reduce pleurodesis failure rates. Adverse effects Adverse effects were inconsistently reported. We performed network meta-analyses for the risk of procedure-related fever and pain. The evidence for risk of developing fever was of low certainty, but suggested there may be little difference between interventions relative to talc slurry (talc poudrage: OR 0.89, 95% Cr-I 0.11 to 6.67; bleomycin: OR 2.33, 95% Cr-I 0.45 to 12.50; IPCs: OR 0.41, 95% Cr-I 0.00 to 50.00; doxycycline: OR 0.85, 95% Cr-I 0.05 to 14.29). Evidence also suggested there may be little difference between interventions in the risk of developing procedure-related pain, relative to talc slurry (talc poudrage: OR 1.26, 95% Cr-I 0.45 to 6.04; very-low certainty; bleomycin: OR 2.85, 95% Cr-I 0.78 to 11.53; low certainty; IPCs: OR 1.30, 95% Cr-I 0.29 to 5.87; low certainty; doxycycline: OR 3.35, 95% Cr-I 0.64 to 19.72; low certainty). Patient-reported control of breathlessness Pair-wise meta-analysis suggests there is likely no difference in breathlessness control, relative to talc slurry, of talc poudrage ((mean difference (MD) 4.00 mm, 95% CI -6.26 to 14.26) on a 100 mm visual analogue scale for breathlessness; studies = 1; participants = 184; moderate certainty) and IPCs without daily drainage (MD -6.12 mm, 95% CI -16.32 to 4.08; studies = 2; participants = 160; low certainty). Overall mortality There may be little difference between interventions when compared to talc slurry (bleomycin and IPC without daily drainage; low certainty) but evidence is uncertain for talc poudrage and doxycycline. Patient acceptability Pair-wise meta-analysis demonstrated that IPCs probably result in a reduced risk of requiring a repeat invasive pleural intervention (OR 0.25, 95% Cr-I 0.13 to 0.48; moderate certainty) relative to talc slurry. There is likely little difference in the risk of repeat invasive pleural intervention with talc poudrage relative to talc slurry (OR 0.96, 95% CI 0.59 to 1.56; moderate certainty). AUTHORS' CONCLUSIONS Based on the available evidence, talc poudrage and talc slurry are effective methods for achieving a pleurodesis, with lower failure rates than a number of other commonly used interventions. IPCs provide an alternative approach; whilst associated with inferior definitive pleurodesis rates, comparable control of breathlessness can probably be achieved, with a lower risk of requiring repeat invasive pleural intervention. Local availability, global experience of agents and adverse events (which may not be identified in randomised trials) and patient preference must be considered when selecting an intervention. Further research is required to delineate the roles of different treatments according to patient characteristics, such as presence of trapped lung. Greater attention to patient-centred outcomes, including breathlessness, quality of life and patient preference is essential to inform clinical decision-making. Careful consideration to minimise the risk of bias and standardise outcome measures is essential for future trial design.

Abstract
Background Malignant pleural effusion is a commonly seen complication of malignancies such as lung and breast cancers. In Western countries, talc is frequently used as a standard therapeutic agent (pleurodesis agent) with the aim of alleviating symptoms including dyspnea and chest pain. Talc is not recognized as a pleurodesis agent in Japan. The aim of this study was to verify the efficacy and safety of sterilized talc (NPC-05) for the introduction of talc in Japan. Methods The study was a single-arm, open-label, investigator-initiated trial conducted jointly at six institutions. The subjects were 30 patients with malignant pleural effusions. A solution of 4 g NPC-05 suspended in 50 ml physiological saline was instilled into the pleural space to perform pleurodesis. Results The efficacy of NPC-05 for pleural adhesion 30 days after pleurodesis was 83.3% (25/30 cases). Amelioration of dyspnea and pain (chest pain) was seen. Commonly seen adverse effects were increased C-reactive protein (CRP) and fever. Nearly all adverse events were phenomena previously reported as adverse effects of talc. No acute respiratory distress syndrome (ARDS) or other serious side effects occurred. Conclusion The efficacy and safety of NPC-05 for malignant pleural effusion in Japanese patients was verified, and the clinical outcomes with talc were confirmed to be the same as previously reported in other countries. There is thought to be a high level of need for this agent in the treatment of malignant pleural effusion in Japan.

Abstract
We report our experience in the treatment of pleural effusion in 25 patients with metastatic breast cancer. Seventeen patients received initial systemic therapy and in 13 of them local intrapleural therapy was subsequently employed; the remaining 8 patients received local therapy only. Several modalities of local treatment were used: intrapleural chemotherapy with thiotepa and 5-fluorouracil; the production of pleural adhesion by the use of chest drainage alone or associated with instillation of sclerosing agents, such as nitrogen mustard or tetracycline. Of the 21 patients who were subjected to local therapy, 19 (90.5%) achieved an objective response (16 complete (76.2%) and 3 (14.34%) partial). Complete responses were observed exclusively in patients who had pleurodesis. Our data suggest that pleurodesis is the treatment of choice for neoplastic pleural effusion and that the use of tetracycline as a sclerosing agent is the most useful because of its availability, low cost and low morbidity.

Abstract
Parenchymal cancers of lung, breast, gastrointestinal tract and ovaries as well as lymphomas and mesotheliomas are among the most common cancer types causing malignant effusions, though almost all tumour types have been reported to cause a malignant effusion. The prognosis heavily depends on patients' response to systemic therapy however, regardless of the causing pathology and histopathologic form, malignant pleural disease is normally associated with a poor prognosis. To date, there are not sufficient data to allow accurate predictions of survival that would facilitate decision making for managing patients with malignant pleural diseases. Interventions are directed towards drainage of the effusion and, when appropriate, concurrent or subsequent pleurodesis or establishing long-term drainage to prevent re-accumulation. The rate of re-accumulation of the pleural effusion, the patient's prognosis, and the severity of the patient's symptoms should guide the subsequent choice of therapy. In contemporary medicine, not many cancers have managed to generate as intense debates concerning treatment, as malignant pleural mesothelioma. The relative advantages of surgery, radiation, chemotherapy and any combination of the three are continuously reassessed and reconsidered, even though not always based on scientific evidence. The aim of surgery in mesothelioma may be prolongation of life, in addition to palliation of symptoms. Longer recovery periods from more extensive surgical procedures could be justified, in carefully selected patients. Surgical options include: Video assisted thoracoscopic (VATS) pleurodesis, VATS partial pleurectomy (VATS PP)-both parietal and visceral; open pleurectomy decortication (PD)-with an extended option (EPD) and extrapleural pneumonectomy (EPP). Current evidence implies that EPD can be performed reliably in specialised centres with good results, both in terms of mortality and survival; however, no operation has yet been shown to be beneficial in a prospective randomized controlled clinical trial.

Abstract
BACKGROUND Malignant pleural effusion (MPE) is a common problem for people with cancer as a result of malignant infiltration of the pleura. It is usually associated with considerable breathlessness. A number of treatment options are available to manage the uncontrolled accumulation of pleural fluid including administration of a pleurodesis agent (either via a chest tube or at thoracoscopy) or indwelling pleural catheter insertion. OBJECTIVES To ascertain the optimal management strategy for adults with malignant pleural effusion in terms of pleurodesis success. Additionally, to quantify differences in patient-reported outcomes and adverse effects between management strategies. SEARCH METHODS We searched The Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid EMBASE; EBSCO CINAHL; SCI-EXPANDED and SSCI (ISI Web of Science) to April 2015. SELECTION CRITERIA We included randomised controlled trials of intrapleural interventions for adults with symptomatic MPE in the review. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data on study design, study characteristics, outcome measures, potential effect modifiers and risk of bias.The primary outcome measure was pleurodesis failure rate. Secondary outcome measures were adverse effects and complications, patient-reported control of breathlessness, quality of life, cost, mortality, duration of inpatient stay and patient acceptability.We performed network meta-analysis with random effects to analyse the primary outcome data and those secondary outcomes with enough data. We also performed pair-wise random-effects meta-analyses of direct comparison data. If interventions were not deemed jointly randomisable, or insufficient data were available, we reported the results by narrative synthesis. We performed sensitivity analyses to explore heterogeneity and to evaluate only those pleurodesis agents administered via a chest tube at the bedside. MAIN RESULTS Of the 1888 records identified, 62 randomised trials, including a total of 3428 patients, were eligible for inclusion. All studies were at high or uncertain risk of bias for at least one domain.Network meta-analysis evaluating the rate of pleurodesis failure, suggested talc poudrage to be a highly effective method (ranked second of 16 (95% credible interval (Cr-I) 1 to 5)) and provided evidence that it resulted in fewer pleurodesis failures than eight other methods. The estimated ranks of other commonly used agents were: talc slurry (fourth; 95% Cr-I 2 to 8), mepacrine (fourth; 95% Cr-I 1 to 10), iodine (fifth; 95% Cr-I 1 to 12), bleomycin (eighth; 95% Cr-I 5 to 11) and doxycyline (tenth; 95% Cr-I 4 to 15). The estimates were imprecise as evidenced by the wide credible intervals and both high statistical and clinical heterogeneity.Most of the secondary outcomes, including adverse events, were inconsistently reported by the included studies and the methods used to describe them varied widely. Hence the majority of the secondary outcomes were reported descriptively in this review. We obtained sufficient data to perform network meta-analysis for the most commonly reported adverse events: pain, fever and mortality. The fever network was imprecise and showed substantial heterogeneity, but suggested placebo caused the least fever (ranked first of 11 (95% Cr-I 1 to 7)) and mepacrine and Corynebacterium parvum (C. parvum) appeared to be associated with the most fever (ranked tenth (95% Cr-I 6 to 11) and eleventh (95% Cr-I 7 to 11) respectively). No differences between interventions were revealed by the network meta-analysis of the pain data. The only potential difference in mortality identified in the mortality network was that those receiving tetracycline appeared to have a longer survival than those receiving mitoxantrone (OR 0.16 (95% Confidence Interval (CI) 0.03 to 0.72)). Indwelling pleural catheters were examined in two randomised studies, both of which reported improved breathlessness when compared to talc slurry pleurodesis, despite lower pleurodesis success rates.The risk of bias in a number of the included studies was substantial, for example the vast majority of studies were unblinded, and the methods used for sequence generation and allocation concealment were often unclear. Overall, however, the risk of bias for all studies was moderate. We have not reported the GRADE quality of evidence for the outcomes, as the role of GRADE is not well established in the context of Network Meta-analysis (NMA). AUTHORS' CONCLUSIONS Based on the available evidence, talc poudrage is a more effective pleurodesis method in MPE than a number of other frequently used methods, including tetracycline and bleomycin. However further data are required to definitively confirm whether it is more effective than certain other commonly used interventions such as talc slurry and doxycycline, particularly in view of the high statistical and clinical heterogeneity within the network and the high risk of bias of many of the included studies. Based on the strength of the evidence from both direct and indirect comparisons of randomised data of sclerosants administered at the bedside, there is no evidence to suggest large differences between the other highly effective methods (talc slurry, mepacrine, iodine and C. parvum). However, local availability, global experience of these agents and their adverse events, which may not be identified in randomised trials, must also be considered when selecting a sclerosant. Further research is required to delineate the roles of different treatments according to patient characteristics (e.g. according to their prognosis or presence of trapped lung) and to explore patient-centred outcomes, such as breathlessness and quality of life, in more detail. Careful consideration to minimise the risk of bias and standardise outcome measures is essential for future trial design.

Abstract
The approach to management of malignant pleural effusions (MPE) has changed over the past few decades. The key goals of MPE management are to relieve patient symptoms using the least invasive means and in the most cost-effective manner. There is now a realization that patient-reported outcome measures should be the primary goal of MPE treatment, and this now is the focus in most clinical trials. Efforts to minimize patient morbidity are complemented by development of less invasive treatments that have mostly replaced the more aggressive surgical approaches of the past. Therapeutic thoracentesis is simple, effective and generally safe, although its benefits may only be temporary. Pleurodesis is the conventional and for a long time the only definitive therapy available. However, the efficacy and safety of talc pleurodesis has been challenged. Indwelling pleural catheter (IPC) drainage is increasingly accepted worldwide and represents a new concept to improve symptoms without necessarily generating pleural symphysis. Recent studies support the effectiveness of IPC treatment and provide reassurance regarding its safety. An unprecedented number of clinical trials are now underway to improve various aspects of MPE care. However, choosing an optimal intervention for MPE in an individual patient remains a challenge due to our limited understanding of the underlying pathophysiology of breathlessness in MPE and a lack of predictors of survival and pleurodesis outcome. This review provides an overview of common pleural interventional procedures used for MPE management, controversies and limitations of current practice, and areas of research most needed to improve practice in future.

Abstract
CONTEXT The difficulties in defining a palliative care patient accentuate the need to provide stringent descriptions of the patient population in palliative care research. OBJECTIVES To conduct a systematic literature review with the aim of identifying which key variables have been used to describe adult palliative care cancer populations in randomized controlled trials (RCTs). METHODS The data sources used were MEDLINE (1950 to January 25, 2010) and Embase (1980 to January 25, 2010), limited to RCTs in adult cancer patients with incurable disease. Forty-three variables were systematically extracted from the eligible articles. RESULTS The review includes 336 articles reporting RCTs in palliative care cancer patients. Age (98%), gender (90%), cancer diagnosis (89%), performance status (45%), and survival (45%) were the most frequently reported variables. A large number of other variables were much less frequently reported. CONCLUSION A substantial variation exists in how palliative care cancer populations are described in RCTs. Few variables are consistently registered and reported. There is a clear need to standardize the reporting. The results from this work will serve as the basis for an international Delphi process with the aim of reaching consensus on a minimum set of descriptors to characterize a palliative care cancer population.

Abstract
Background Talc pleurodesis has been widely used to control malignant pleural effusion; however, it is still not clear whether talc pleurodesis is more effective than other local therapies. We performed a meta-analysis to evaluate the efficacy and safety of talc pleurodesis in the management of malignant pleural effusion. Methods PubMed, Embase, and Web of Science were searched for English-language studies of clinical controlled trials comparing talc pleurodesis with control therapies until August 8, 2013. Success rate and incidence of adverse events were evaluated. Relative risks were estimated using random- or fixed- effects model and statistical heterogeneity was assessed using I2 test. Results Twenty trials involving 1,525 patients with malignant pleural effusion were included. The success rate of talc pleurodesis was significantly higher than that of control therapies (relative risk, 1.21; 95% confidence interval, 1.01–1.45; p = 0.035) with similar adverse events. In addition, thoracoscopic talc poudrage was more effective than bedside talc slurry (relative risk, 1.12; 95% confidence interval, 1.01–1.23; p = 0.026). Conclusions The current evidences suggested the benefit for talc pleurodesis in the treatment of malignant pleural effusion. Talc pleurodesis, especially thoracoscopic talc poudrage pleurodesis, should be performed in patients with malignant pleural effusion, especially those with life-expectancy longer than one month.

Abstract
Malignant pleural effusions are a cause of significant symptoms and distress in patients with end-stage malignancies and portend a poor prognosis. Management is aimed at symptom relief, with minimally invasive interventions and minimal requirement for hospital length of stay. The management options include watchful waiting if no symptoms are present, repeat thoracentesis, medical or surgical thoracoscopic techniques to achieve pleurodesis, pleuroperitoneal shunts, placement of tunneled pleural catheters, or a combination of modalities. To determine the best modality for management, patients must be assessed individually with concern for symptoms, functional status, prognosis, and their social and financial situations.

Abstract
Malignant pleural effusion is a common clinical problem. Evacuation of the pleural fluid and prevention of its reaccumulation are the main aims of management. Pleurodesis should be attempted early, although considerable practice variations exist in the way it is performed. There is a lack of consensus among respiratory physicians worldwide on the optimal method and agent for pleurodesis. Talc remains the most commonly used pleurodesing compound in most countries. While talc produces a higher success rate than other compounds, it generates more side-effects. The association between talc and ARDS continues to be debated. Ambulatory small-bore pleural catheter drainage followed by intrapleural instillation of a pleurodesing agent is increasingly accepted as an alternative to conventional in-patient pleurodesis. Development of novel methods to control pleural fluid formation should be made a high priority in future pleural research.

Abstract
BACKGROUND It is widely believed that baseline imbalances in randomized trials must necessarily be random. In fact, there is a type of selection bias that can cause substantial, systematic and reproducible baseline imbalances of prognostic covariates even in properly randomized trials. It is possible, given complete data, to quantify both the susceptibility of a given trial to this type of selection bias and the extent to which selection bias appears to have caused either observable or unobservable baseline imbalances. Yet, in articles reporting on randomized trials, it is uncommon to find either these assessments or the information that would enable a reader to conduct them. Nevertheless, there have been a few published reports that contain descriptions of either this type of selection bias or indicators that it may have occurred. OBJECTIVE To document that the same type of selection bias has been described in numerous randomized trials and therefore that it represents a problem deserving of greater attention. STUDY SELECTION Computerized searches were not useful in locating trials with one or more elements that contribute to or are indicative of selection bias in randomized trials. We limit our treatment to trials that were previously questioned for susceptibility to selection bias or for large baseline imbalances. RESULTS We found 14 randomized trials that appear to be suspicious for selection bias. This may represent only the tip of the iceberg, because the status of other trials is inconclusive. CONCLUSIONS Authors of clinical trial reports should be required to disclose sufficient details to allow for an assessment of both allocation concealment and selection bias. The extent to which a randomized study was susceptible to selection bias should be considered in determining the relative contribution it makes to any subsequent meta-analysis, policy or decision.

Abstract
Management of recurrent malignant pleural effusion, a common complication of malignancy, poses a challenge to clinicians. Although almost one century has elapsed since the introduction of the pleurodesis procedure, the ideal approach and best agent are still to be defined. Optimally, pleurodesis should be done at the bedside with a minimally invasive procedure, and suitable agents to achieve pleural symphysis should be inexpensive, available worldwide and free of adverse effects. To date, no substance completely fulfills these requirements. Silver nitrate should be considered for pleurodesis because of its low cost and ease of handling. Although talc has been used most frequently to induce pleurodesis, reports of death due to acute respiratory failure have raised concerns about the safety of this agent. Tetracycline, an effective alternative used in the past, is no longer commercially available. This agent has been substituted with derivatives of tetracycline, such as minocycline and doxycycline with success rates similar to those with tetracycline. Several antineoplastic agents have been injected into the pleural space with the aim of producing pleural symphysis, the most representative of this group being bleomycin. Recent knowledge of the molecular mechanisms involved in pleural inflammation has brought into focus new substances, such as transforming growth factor beta and vascular endothelial growth factor, which may be used as pleurodesis agents in the future. Nevertheless, more studies are necessary to better define the potential of these substances in the induction of pleural symphysis.Ideally, a sclerosing agent should be cost-effective, available worldwide and easily administered. Talc will probably stand as the preferred agent to be used for pleurodesis in malignant pleural effusion because of its efficacy, easy manipulation and handling. However, further investigation is necessary to minimize adverse effects related to talc.

Abstract
BACKGROUND Approximately half of all patients with metastatic cancer develop a malignant pleural effusion which is likely to lead to a significant reduction in quality of life secondary to symptoms such as dyspnoea and cough. The aim of pleurodesis in these patients is to prevent re-accumulation of the effusion and thereby of symptoms, and avoid the need for repeated hospitalization for thoracocentesis. Numerous clinical studies have been performed to try to determine the optimal pleurodesis strategy, and synthesis of the available evidence should facilitate this. OBJECTIVES The aims of this review were to ascertain the optimal technique of pleurodesis in cases of malignant pleural effusion; to confirm the need for a sclerosant; and to clarify which, if any, of the sclerosants is the most effective. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials was searched for studies on 'pleurodesis'. Studies for inclusion were also identified from MEDLINE (1980 to June 2002) and EMBASE (1980 to May 2002). No language restriction was applied. SELECTION CRITERIA RCTs of adults subjects undergoing pleurodesis for pleural effusion in the context of metastatic malignancy (or a malignant process leading to pleural effusion) were included. DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies for inclusion in the review, and extracted data using a standard data collection form. Primary outcome measures sought were effectiveness of pleurodesis as defined by freedom from recurrence of effusions, and mortality after pleurodesis. Secondary outcomes were adverse events due to pleurodesis. Dichotomous data were meta-analysed using a fixed effect model and expressed as relative risk. The number-needed-to-treat (NNT) was calculated for pleurodesis efficacy. In addition, for adverse events, the overall percentage of patients across studies exhibiting a particular adverse effect such as fever, pain, or gastrointestinal symptoms was calculated. MAIN RESULTS A total of 36 RCTs with 1499 subjects were eligible for meta-analysis. The use of sclerosants (mitozantrone, talc and tetracycline combined)compared with control (instillation of isotonic saline or equivalent pH isotonic saline or tube drainage alone) was associated with an increased efficacy of pleurodesis. The relative risk (RR) of non-recurrence of an effusion is 1.20 (95% CI 1.04 to 1.38) in favour of the use of sclerosants based on five studies with a total 228 subjects. Comparing different sclerosants, talc was found to be the most efficacious. The RR of effusion non-recurrence was 1.34 (95% CI 1.16 to 1.55) in favour of talc compared with bleomycin, tetracycline, mustine or tube drainage alone based on 10 studies comprising 308 subjects. This was not associated with increased mortality post pleurodesis. The RR of death was 1.19 (95% CI 0.08 to 1.77) for talc compared to bleomycin, tetracycline, mustine and tube drainage alone based on six studies of 186 subjects. Death was not reported in all studies and, when reported, was attributed to underlying disease, only one death being reported as procedure-related. In the comparison of thoracoscopic versus medical pleurodesis, thoracoscopic pleurodesis was found to be more effective. The RR of non-recurrence of effusion is 1.19 (95% CI 1.04 to 1.36) in favour of thoracoscopic pleurodesis compared with tube thoracostamy pleurodesis utilizing talc as sclerosant based on two studies with 112 subjects. Comparing thoracoscopic versus bedside instillation (with different sized chest tubes) of various sclerosants (tetracycline, bleomycin, talc or mustine) the RR of non-recurrence of effusion is 1.68 (95% CI 1.35 to 2.10) based on five studies with a total of 145 participants.Adverse events were not reported adequately to enable meta-analysis. REVIEWER'S CONCLUSIONS The available evidence supports the need for chemical sclerosants for successful pleurodesis, the use of talc as the sclerosant of choice, and thoracoscopic pleurodesis as the preferred technique for pleurodesis based on efficacy. There was no evidence for an increase in mortality following talc pleurodesis.

Abstract
The majority of patients who acquire lung cancer will have troublesome symptoms at some time during the course of their disease. Some of the symptoms are common to many types of cancers, while others are more often encountered with lung cancer than other primary sites. The most common symptoms are pain, dyspnea, and cough. This document will address the management of these symptoms, and it will also address the palliation of specific problems that are commonly seen in lung cancer: metastases to the brain, spinal cord, and bones; hemoptysis; tracheoesophageal fistula; and obstruction of the superior vena cava.

Abstract
Because the severity of most diseases can be measured nonuniquely, different medical interventions with different mechanisms of action may be evaluated differently, even in the same patient population. Complicating this further is the fact that even for a given medical intervention, it may not be clear which endpoint, if any, will be most likely to show an intervention effect. For these and other reasons, clinical trials typically involve the evaluation of multiple safety and efficacy endpoints. As information accrues about diseases and patient populations, some endpoints may cease to be useful, but the trend would still likely be toward increasing numbers of potential endpoints. This trend would provide sponsors with increasing numbers of choices for the primary efficacy endpoint. If the endpoint selected as primary is not the optimal one for demonstrating the superiority of the experimental medical intervention, then a safe and effective medical intervention may be mistakenly found to be otherwise. On the other hand, the sponsor may find the endpoint that makes its case and not study other endpoints that would have shown the experimental intervention to be inferior, in some way, to the control intervention. As such, the reliance of medical decisions on narrow primary endpoints can lead to inflation of both the type I and type II error rates. To address these concerns, we propose that all endpoints, especially the primary endpoint, be as informative as possible. This could be accomplished by combining some endpoints into composite endpoints. To avoid losing information in this transformation, we define the concept of information-preserving composite endpoints and provide information concerning when this type of composite endpoint would be most useful. Specifically, we define the concept of joint fusibility of a set of endpoints and note that this property confers upon the derived information-preserving composite endpoint the greatest amenability to statistical analysis. We also point out that using composite endpoints allows sponsors the most discretion in selecting their primary between-group statistical analysis. We illustrate these ideas with examples from a variety of therapeutic areas.

Abstract
Malignancy is one of the most common causes of exudative effusions and increases in incidence in the elderly. Lung cancer is the most common cause of malignant effusion caused by contiguous spread and its propensity to invade the pulmonary vasculature and embolize to the visceral pleura. Lung, breast, ovary, and gastric cancer and lymphomas account for about 80% of all malignant effusions. Dyspnea and cough are the most common symptoms at presentation. Thirty percent of patients have a low pleural fluid pH (> or = 7.30) and glucose (> 60 mg/dL) at presentation, which predicts a decreased survival, an increase yield on diagnostic studies, and a poor response to chemical pleurodesis. Talc by poudrage or slurry is the most successful pleurodesis agent. Pleural peritoneal shunt is an option for patients with an intractable, symptomatic malignant effusion who cannot undergo or who have failed pleurodesis.

Abstract
Malignant pleural effusions (MPEs) represent a common complication of advanced malignancies. However, adequate palliation of this highly symptomatic accompaniment to cancer can be achieved in most patients by adopting the appropriate therapy. Several options are available for the treatment of MPE. Systemic therapy may control the effusion in patients whose underlying malignancy is sensitive to anti-cancer agents. Repeated thoracocentesis can be appropriate for patients with limited life expectancy or slowly recurrent effusions. In the majority of the remaining cases the treatment of choice is pleurodesis with sclerosing agents administered via tube thoracostomy. Controversy still exists as to which drug produces the best results: talc and bleomycin appear to be among the most cost-effective agents. The debate over the best agent to be used for pleurodesis refers to the difficulty in comparing results of studies using different eligibility criteria, response assessment and end-points. This article describes the various treatments which have been reported in the literature to play a role in the management of MPEs. It is also aimed at providing guidelines in allocating patients to appropriate treatments.

Abstract
Twenty-one patients with malignant pleural effusion (MPE) were prospectively entered into a nonrandomized, single-armed study to evaluate the efficacy and safety of recombinant interferon (IFN) alpha-2b (INTRON A; Schering-Plough; Kenilworth, NJ) as an intrapleural palliative agent. From March 1989 through February 1993 (48 months), 21 patients were entered into the study. No symptomatic effusion recurred and no substantial side effects were associated with treatment. This suggests recombinant IFN alpha-2b represents a safe and effective intrapleural agent for the palliation of MPE.

Abstract
Pleural effusions are a severe complication of advanced malignant disease. Palliative treatment strategies should be simple and effective. We investigated iodized talc pleurodesis through tube thoracostomy for this purpose. A total of 43 patients received a suspension of 5 g talc with 3 g thymol iodine via chest tube. The procedure was well tolerated without major complications in all cases. Unfortunately, 4 patients died of disease within the 1st month after treatment, so that only 39 patients were evaluable for treatment outcome. Follow-up ranged from 1 to 14 months. The success rate after 3 months was 92.5%. In conclusion, iodized talc pleurodesis is an excellent tool in the palliative management of malignant pleural effusions. Administration via chest tube is sufficient for treatment success.

Abstract
OBJECTIVE To assess the efficacy, permanence, and safety of thoracoscopic talc poudrage (TTP) for pleurodesis in malignant effusions. DESIGN Retrospective. PARTICIPANTS Patients with lifetime follow-up who received TTP in two related centers in Marseilles, France. RESULTS Three hundred sixty patients were included in this study: 88 had mesothelioma and 272 had pleural metastases. The mean follow-up time was 12 months (2 to 120). Of the 327 patients whose response could be evaluated, 90.2% had a successful pleurodesis at 1 month, and 82.1% had a life-long pleural symphysis. Adverse effects included 1 death 3 days after the procedure in a patient with end-stage disease, fever (9.8%), empyema (2.5%), pulmonary infection (0.8%), and malignant invasion of the scar (1 patient). CONCLUSIONS TTP is an effective and safe method of lifelong pleurodesis. It should be performed early on in the history of malignant effusions to avoid the risk of respiratory failure, this being directly linked to the general and respiratory status of the patients at the time of the procedure.

OBJECTIVE To determine the efficacy and safety of talc slurry for pleurodesis. DESIGN Retrospective. PARTICIPANTS All patients who received talc slurry via tube thoracostomy at Memorial Sloan-Kettering Cancer Center from March 1991 to April 1992. RESULTS Fifty-eight patients received talc slurry in 75 procedures; five patients had 2 unilateral procedures and 12 had bilateral procedures. Fifty-two patients had malignant pleural effusions with the most common cell types being breast (23 of 52, 44 percent), lung (4 of 52, 8 percent), ovarian (4 of 52, 8 percent), and endometrial (3 of 52, 6 percent). Four patients had benign conditions. The mean duration of follow-up was 171 days (range, 2 to 450 days). Success, defined as the absence of pleural fluid reaccumulation, was evaluable in 47 of 73 (64 percent) procedures. Pleurodesis was successful in 38 of 47 (81 percent). Adverse effects associated with pleurodesis included fever (46 of 73, 63 percent), empyema (4 of 73, 5 percent), atrial arrhythmia (3 of 73, 4 percent), hypotension (3 of 73, 4 percent), and hypoxemic respiratory failure (3 of 73, 4 percent). There were no deaths attributable to the procedure. CONCLUSIONS Talc slurry instilled through a chest tube is an effective bedside method of pleurodesis. Fever occurs frequently. Respiratory failure is a rare but potentially serious complication that deserves further investigation.

Abstract
Several options are available for treatment of malignant pleural effusions in patients with non-small-cell lung cancer. Repeat thoracentesis may be appropriate for the patient with limited survival and a slowly recurrent effusion. Pleurodesis with a sclerosing agent administered via a chest tube is the most widely used therapy, though controversy exists as to which drug produces the best results. Pleuroperitoneal shunting remains an option for those patients whose lung is trapped by tumor. Video-assisted thoracoscopy is likely to change the treatment patterns of malignant pleural effusion. Thoracoscopic pleurectomy can be performed with minimal morbidity. Alternatively, sclerosing agents such as talc can be easily and uniformly introduced into the thoracic cavity under thoracoscopic control. Future therapy is likely to entail a diagnostic thoracentesis followed by a definitive thoracoscopic procedure.

Abstract
The management of patients with metastatic breast cancer is best achieved by the judicious use of local and systemic measures that palliate symptoms and improve overall quality of life. When two treatment approaches are known to be equally efficacious, the less toxic should be used. When disease is limited to one or two sites and the patient has an indolent form of the disease, the patient's symptoms are often best palliated with the use of surgery or radiotherapy alone. When multiple sites of disease are evident or the disease is progressing more rapidly, systemic therapy is preferred, and local therapies should be added when the patient is clearly refractory to systemic therapy or when the disease site is unlikely to be adequately palliated with systemic therapy. The use of any of these therapies, including chemotherapy, has a relatively small effect on the median survival of patients with metastatic breast cancer. However, improvements in quality of life are usually greatest with regimens inducing the highest response rates, even when these regimens are associated with greater toxicity. The characteristics of patients likely to respond to endocrine therapy are well defined; in these patients endocrine therapy should be used as the first form of systemic therapy. Among endocrine therapies, the least toxic is used first. The selection of patients for chemotherapy is largely a process of exclusion. When chemotherapy is used, there are a number of different strategies for sequencing chemotherapy that appear to be equally efficacious. In general, patients should be treated with standard doses of drug combinations for a period in excess of 3 months. When used inappropriately, especially in asymptomatic patients, these therapies may actually compromise the patient's quality of life. The use of surgery, radiation therapy, and systemic therapy should be integrated with various types of psychosupport services, especially peer support groups. Patients who want to try new forms of therapy should do so early in the course of the disease when these therapies are most likely to be effective and the patient has the least to lose if the therapy proves ineffective. This is especially true because the use of the most effective regimens at a time when the patient is asymptomatic may mean that the patient is resistant to most or all therapies of proven value when most in need of palliation.

Abstract
Malignant pleural effusions are often symptomatic and tend to recur after simple aspiration. Pleurodesis may prevent recurrence of the effusion; many agents and techniques have been described. A questionnaire was sent to 448 clinicians in the United Kingdom to determine how pleurodesis is performed in practice. There was a 56% overall response, with replies from 101 respiratory physicians, 88 general physicians, 29 thoracic surgeons, and 35 general surgeons. General surgeons saw few cases of malignant pleural effusion and rarely performed pleurodesis. A patient with recurrent malignant pleural effusion would usually be managed with pleurodesis by 76 (76%) respiratory physicians, 26 (30%) general physicians, and 23 (81%) thoracic surgeons; a further 29 (33%) general physicians would refer such patients to another specialist. Most medical pleurodesis were performed by junior staff, whereas consultant thoracic surgeons were more likely to be concerned with the procedure. All the thoracic surgeons used an intercostal tube drain, usually with suction. An intercostal tube drain was used routinely by only 54 (54%) of the respiratory physicians and 28 (32%) general physicians. Thoracic surgeons preferred talc for pleurodesis whereas physicians most commonly used tetracycline. The variety of methods in use supports the need for randomised, controlled studies to determine the most effective technique of pleurodesis.

Abstract
The indications, technique, and results of thoracoscopic talc poudrage in the two clinical settings of pneumothorax and recurrent pleural effusion in chronically ill patients are reported. Forty patients underwent this treatment between May 1982 and September 1989. The patients ranged in age from 10 months to 78 years. Of the 20 patients who underwent treatment of pneumothorax, 9 had cystic fibrosis, 7 had severe chronic obstructive pulmonary disease, 2 had spontaneous pneumothoraces, and 2 had postoperative parenchymal bronchopleural fistulas. Nineteen patients (95%) had successful treatment. Of the 20 patients who underwent treatment of chronic effusions, 14 had malignant etiologies, 3 had chylothoraces, and 3 had other miscellaneous effusions. Eighteen patients (90%) in this group had successful treatment. There were two hospital deaths related to the underlying disease processes after the pleural space problems were successfully treated. This study suggests that proper selection of patients and full exploitation of the capabilities of thoracoscopy and talc poudrage will result in effective treatment with low morbidity and mortality.

Abstract
In a prospective randomized study, patients with pleural effusions secondary to breast carcinoma were randomly allocated to be treated by pleurodesis using either intracavitary talc or bleomycin. For 25 assessable treatments in 22 patients, recurrence of effusion was observed in 5 of 15 (33 per cent) of the bleomycin group compared with none in the talc group. It is concluded that talc is superior to bleomycin in controlling pleural effusions secondary to breast carcinoma, but bleomycin may have a role in patients unfit for general anaesthesia or with extensive disease elsewhere.

Abstract
This paper briefly reviews the incidence of malignant pleural effusions (MPE) and the measures that have been used to treat this condition. The role of intracavitary bleomycin in controlling MPE, the doses used, and morbidity associated with its use are reviewed in depth with reference to multicenter studies that the author has coordinated as well as the published literature. The short- and long-term results reported when bleomycin was used alone or as compared with other agents are discussed. The author concludes that intracavitary bleomycin is an effective agent comparable to, if not more effective than, most agents used to prevent the recurrence of MPE after simple drainage procedures: it is safe and convenient to use; toxicity is low with minimal side effects and no myelosuppression. It can be safely administered to immunocomprised patients and those undergoing systemic chemotherapy.

Abstract
Pleural effusions are common in cancer patients, developing either from the malignant condition or from unrelated causes, such as congestive heart failure, pulmonary infarction, or infection. Diagnosis of malignant pleural effusion rests on demonstration of the presence of malignant cells in the pleural fluid or pleural biopsy specimen. Treatment is usually aimed at relief of symptoms rather than at the underlying malignancy. Specific therapeutic measures include thoracentesis, chest tube drainage, pleurodesis with chemicals or biologic agents, radiation and systemic chemotherapy, surgical pleurodesis, and pleuroperitoneal shunt. These should be supplemented by ancillary measures to maintain fluid and nutritional balance and prevent complications.

Abstract
Forty-one patients with malignant pleural effusions secondary to breast cancer were randomly allocated to treatment with either intracavitary talc or intracavitary tetracycline. Of 33 evaluable patients, radiological control was achieved in 11/12 (92%) of the talc group compared with 10/21 (48%) of the tetracycline group (P = 0.022). Intracavitary talc provides effective palliation of metastatic pleural effusions secondary to breast cancer.
