Role of blind closed pleural biopsy in the managment of pleural exudates

Non-specific pleuritis: long-term follow-up outcomes

BACKGROUND

The definitive etiology of nonspecific pleuritis (NSP), the influence of the type of pleural biopsy on clinical results and the minimum duration of follow-up is controversial.

RESEARCH DESIGN AND METHODS

A retrospective, observational study of patients ≥ 18 years with NSP confirmed by closed pleural biopsy (CPB), local anesthesia pleuroscopy (LAP), or video-assisted thoracic surgery (VATS).

RESULTS

A total of 167 patients were included (mean follow-up, 14.4 months), of which 25 (15%) were diagnosed within one month; [15 (60%) malignant]. Of the remaining 142 pleural effusions (PEf), 69 (48.6%) were idiopathic; 49 (34.5%) not-malignant and 24 (16.9%) malignant (4 mesotheliomas and 20 metastasic). The diagnosis of NSP was established by CPB (7; median time to diagnosis, 9.4 months), LAT (5; 15.8 months), and VATS (8; 13.5 months) (p = 0.606). Sixty-eight patients (40.7%) died during follow-up (mean time, 12 months).

CONCLUSIONS

In a substantial percentage of patients diagnosed with NSP, a definitive diagnosis will not be obtained, a relevant number of patients will develop a malignant PEf. The diagnostic procedure used for the diagnosis of NSP does not seem to influence delay in the diagnosis of malignant PEf. The data obtained suggest that follow-up should be maintained for at least 24 months.

Study on the application of percutaneous closed pleural brushing combined with cell block technique in the diagnosis of malignant pleural effusion

INTRODUCTION

This study was to investigate the diagnostic value of percutaneous closed pleural brushing (CPBR) followed by cell block technique for malignant pleural effusion (MPE) and the predictive efficacy of pleural fluid carcinoembryonic antigen (CEA) for epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma patients with MPE.

METHODS

All patients underwent closed pleural biopsy (CPB) and CPBR followed by cell block examination. MPE-positive diagnostic rates between the two methods were compared. Univariate and multivariate analyses were performed to determine factors influencing the EGFR mutations. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of pleural fluid CEA for EGFR mutations.

RESULTS

The cumulative positive diagnostic rates for MPE after single and twice CPBR followed by cell block examination were 80.5% and 89.0%, higher than CPB (45.7%, 54.3%) (P < 0.001). Univariate analysis showed that EGFR mutation was associated with pleural fluid and serum CEA (P < 0.05). Multivariate analysis showed that pleural fluid CEA was an independent risk factor for predicting EGFR mutation (P < 0.001). The area under the curve (AUC) of pleural fluid CEA for EGFR mutation prediction was 0.774, higher than serum CEA (P = 0.043), but no difference with the combined test (P > 0.05).

CONCLUSION

Compared with CPB, CPBR followed by the cell block technique can significantly increase the positive diagnostic rate of suspected MPE. CEA testing of pleural fluid after CPBR has a high predictive efficacy for EGFR mutation in lung adenocarcinoma patients with MPE, implying pleural fluid extracted for cell block after CPBR may be an ideal specimen for genetic testing.

Expert Review on Contemporary Management of Common Benign Pleural Effusions

Heart failure (HF) and cirrhosis are frequently associated with pleural effusions (PEs). Despite their apparently benign nature, both HF-related effusions and hepatic hydrothorax (HH) have poor prognosis because they represent an advanced stage of the disease. Optimization of medical therapy in these two entities involve not only the use of diuretics, but also other pharmacological therapies. For instance, all HF patients with reduced or mildly reduced left ventricular ejection fraction can benefit from angiotensin receptor-neprilysin inhibitors, beta blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter 2 inhibitors. Conversely, it is better for HH patients to avoid nonselective beta blockers. Refractory cardiac- and cirrhosis-related PEs are commonly managed by iterative therapeutic thoracentesis. When repeated aspirations are needed, thereby diminishing quality of life, the insertion of an indwelling pleural catheter (IPC) may be warranted. However, in selected HH patients who are diuretic-resistant or diuretic-intractable, placement of transjugular intrahepatic portosystemic shunts should be considered as a bridge to liver transplantation, whereas in transplant candidates the role of IPC is debatable. Another benign condition, pleural tuberculosis (TB) is a serious health problem in developing countries. Diagnostic certainty is still a concern due to the paucibacillary nature of the infection, although the use of more sensitive nucleic acid amplification tests is becoming more widespread. Its treatment is the same as that of pulmonary TB, but the potential drug interactions between antiretroviral and anti-TB drugs in HIV-coinfected patients as well as the current recommended guidelines for the different types of anti-TB drugs resistance should be followed.

The Diagnostic Value of Medical Thoracoscopy Pleural Biopsy, Ultrasound-guided Pleural Biopsy, and Closed Pleural Biopsy in Tuberculous Pleurisy: A propensity score matching analysis.. [DOI: 10.21203/rs.3.rs-2099835/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Background and objective For diagnosis of exudative pleural effusion in tuberculous pleurisy, medical thoracoscopic pleural biopsy (MTPB) enables direct vision and is most widely applied, although ultrasound-guided pleural biopsy (USPB) and closed pleural biopsy (CPB) are also viable. This retrospective study compared the diagnostic efficiencies and safety of USPB, CPB, and MTPB. Methods Patients enrolled from 2014 through 2020 underwent USPB, CPB, or MTPB (n = 69, 69, and 110, respectively). Propensity score matching (PSM) analysis was used to compare the diagnostic sensitivities of CPB, MTPB, and USPB. The secondary outcomes were postoperative complications and hospitalization stay. Results PSM analysis resulted in 40 (USPB vs. CPB), 47 (USPB vs. MTPB), and 52 (CPB vs. MTPB) matched pairs. The diagnostic sensitivities of the USPB and CPB groups were 72.5% and 55.0% (P = 0.162); that of USPB and MTPB were 70.2% and 80.9% (P = 0.337); the CPB and MTPB groups were comparable(P = 0.152). The rates of associated pain and subcutaneous emphysema of the MTPB group were higher than that of the USPB or CPB (P = 0.000, both).Hospitalization time of the MTPB group was longest, and significantly longer than that of the USPB (P = 0.029). Conclusions While the three techniques were similarly effective in diagnosing tuberculous pleurisy, USPB and CPB showed fewer associated complications and shorter hospital stays compared with MTPB. The image guidance offered by USPB benefited reduction in postoperative complications.

The Clinical Experience of Mycobacterial Culture Yield of Pleural Tissue by Pleuroscopic Pleural Biopsy among Tuberculous Pleurisy Patients

Background and Objectives: Tuberculous pleurisy is a common extrapulmonary TB that poses a health threat. However, diagnosis of TB pleurisy is challenging because of the low positivity rate of pleural effusion mycobacterial culture and difficulty in retrieval of optimal pleural tissue. This study aimed to investigate the efficacy of mycobacterial culture from pleural tissue, obtained by forceps biopsy through medical pleuroscopy, in the diagnosis of TB pleurisy. Materials and Methods: This study retrospectively enrolled 68 TB pleurisy patients. Among them, 46 patients received semi-rigid pleuroscopy from April 2016 to March 2021 in a tertiary hospital. We analyzed the mycobacterial culture from pleural tissue obtained by forceps biopsy. Results: The average age of the study participants was 62.8 years, and 64.7% of them were men. In the pleuroscopic group, the sensitivity of positive Mycobacterium tuberculosis (M. TB) cultures for sputum, pleural effusion, and pleural tissue were 35.7% (15/42), 34.8% (16/46), and 78.3% (18/23), respectively. High sensitivities of M. TB culture from pleural tissue were up to 94.4% and 91.7% when pleural characteristic patterns showed adhesion lesions and both adhesion lesions and presence of micronodules, respectively. Conclusions: M. TB culture from pleural tissue should be considered a routine test when facing unknown pleural effusion during pleuroscopic examination.

Diagnosis and Management of Malignant Pleural Effusion: A Decade in Review

Malignant pleural effusion (MPE) is a common complication of thoracic and extrathoracic malignancies and is associated with high mortality. Treatment is mainly palliative, with symptomatic management achieved via effusion drainage and pleurodesis. Pleurodesis may be hastened by administering a sclerosing agent through a thoracostomy tube, thoracoscopy, or an indwelling pleural catheter (IPC). Over the last decade, several randomized controlled studies shaped the current management of MPE in favor of an outpatient-based approach with a notable increase in IPC usage. Patient preferences remain essential in choosing optimal therapy, especially when the lung is expandable. In this article, we reviewed the last 10 to 15 years of MPE literature with a particular focus on the diagnosis and evolving management.

Cytological Diagnostic Procedures in Malignant Mesothelioma

Malignant mesotheliomas (MM) are rare tumors with high mortality rates, whose incidence varies regionally and nationally, and the diagnosis is difficult. Histology-based diagnosis is considered the gold standard despite its low sensitivity of 57-84%. However, recent advances in cytological analysis offer promise for diagnostic advancements. In this study, we reappraised the current cytological guidelines for the MM diagnosis and concluded on their practicability and reliability. The study included 5731 consecutive specimens of pleural effusions from 4552 patients (3026 males of the average age of 67.5 years and 1526 females of the average age of 65.4 years) between December 2017 and January 2000. Out of these patients, 444 (9.8%) were diagnosed with MM. The effusions were examined by immunocytochemistry using routine Giemsa staining. Additionally, hyaluronic acid (HA) was assessed. Cytological findings confirmed 223 out of the 444 MM. The additional 88 cases with negative cytology were corroborated by supplemental assessments of HA above 30 mg/L. Cytological evaluation accomplished the sensitivity of 0.50, specificity of 0.99, and a positive predictive value (PPV) of 0.97 for MM diagnosis. The use of HA determination raised the sensitivity to 0.70 without affecting the specificity or PPV. We conclude that cytological evaluation of effusions aided by the assessment of HA demonstrates the diagnostic sensitivity and specificity for MM no less than the hitherto standard histological evaluation. The cytology-based MM diagnosis may thus be routinely considered when MM is suspected and may offer confirmatory advantages in difficult or doubtful diagnostic cases.

Malignant Pleural Effusions

Malignant pleural effusions have a significant burden on patients and the health care system. Diagnosis is typically via thoracentesis, although other times more invasive procedures are required. Management centers around relief of dyspnea and patient quality of life and can be done via serial thoracentesis, indwelling pleural catheter, or pleurodesis. This article focuses on the diagnosis and management of malignant pleural effusion.

Propensity-score-matching analysis to compare efficacy and safety between 16-gauge and 18-gauge needle in ultrasound-guided biopsy for peripheral pulmonary lesions

Background

Definitive diagnosis of peripheral pulmonary lesions (PPLs) depends on the histological analysis of the pleural biopsy sample. Ultrasound (US)-guided sampling is now standard practice in the clinical setting. However, determining a suitable needle size and sampling times to improve the efficacy and safety of the biopsy remains challenging. Here, we compared the efficacy between 16- and 18-gauge core biopsy needles in US-guided percutaneous transthoracic biopsy for PPLs on histological diagnosis and procedure-related complications.

Materials and methods

In total, 1169 patients (767 men, 402 women; mean age, 59.4 ± 13.2 years) who received biopsy for PPLs between September 2011 and February 2019 were included. The propensity score matching (PSM) analysis was performed to adjust the baseline differences, and the rate of successful specimen assessment and complications were compared between the 16-gauge (249 patients) and 18-gauge (920 patients) groups. The number of pleural surfaces crossed (NOPSC) was defined as the number of times the visceral pleural surface was transgressed. Stratified analysis was performed based on NOPSC.

Results

The overall success rate was 92.0% (1076/1169). The overall complication rate was 9.6%, including pneumothorax, hemorrhage, and vasovagal reaction, which occurred in 2.5% (29/1169), 6.6% (77/1169), and 0.5% (6/1169) of the patients, respectively. When NOPSC was 1 or > 2, the success and complication rates in the 16-gauge group were comparable to those of the 18-gauge group (all P > 0.05). When the NOPSC was 2, the success rate in the 16-gauge group was significantly higher than that in the 18-gauge group (P = 0.017), whereas the complication rate was comparable (P > 0.05).

Conclusion

Higher success rate could be achieved using a 16-gauge than an 18-gauge core biopsy needle in the US-guided percutaneous transthoracic biopsy for PPLs when the NOPSC was 2. We recommend using 16-gauge needles with 2 times of needle passes in biopsy for PPLs in clinical practice.

The diagnostic yield of closed needle pleural biopsy in exudative pleural effusion: a retrospective 10-year study

Background

Pleural effusion is a common presentation in clinical practice. About 40% of exudative pleural effusion is unable to be diagnosed through thoracentesis, and closed pleural biopsy (CPB) is needed. This study was designed to investigate the diagnostic yield of CPB in exudative pleural effusion.

Methods

This was a retrospective 10-year study of patients with unexplained exudative pleural effusion who underwent CPB in two centers. Malignant pleural effusion (MPE) was diagnosed when there was histopathological evidence of pleural tissue, pulmonary tissue, or pleural fluid. Tuberculous pleural effusion (TPE) was confirmed when granuloma or coagulative necrosis was observed in pleural tissue, Ziehl-Neelsen acid-fast staining was positive, or adenosine deaminase (ADA) in pleural effusion was higher than 35IU with clinical symptoms of TB orγ-interferon increased with symptoms of TB.

Results

A total of 644 patients were enrolled, of which 479 were specifically diagnosed (217 patients with TPE and 262 patients with MPE). The sensitivity of CPB in the diagnosis of MPE was 51.5%. Among the pathological types of MPE, lung adenocarcinoma accounted for 77.9% (204/262) of cases, making up the largest proportion. The sensitivity of CPB for diagnosing TPE was 68.7%.

Conclusions

CPB has a relatively high sensitivity in the diagnosis of exudative pleural fluid, especially in relation to tuberculous lesions. CPB could provide an alternative technique in clinical practice, especially for basic hospital units without thoracoscopy.

Accuracy of closed pleural biopsy in the diagnosis of malignant pleural effusion

OBJECTIVE

Previous studies have demonstrated that closed pleural biopsy (CPB) has a sensitivity of less than 60% for diagnosing malignancy. Therefore, controversy has recently emerged regarding the value of CPB as a diagnostic test. Our objective was to assess the accuracy of CPB in diagnosing malignancy in patients with pleural effusion.

METHODS

This was a prospective 8-year study of individuals who underwent CPB to establish the etiology of pleural effusion. Information on each patient was obtained from anatomopathological reports and medical records. When CPB findings showed malignancy or tuberculosis, the biopsy was considered diagnostic, and that was the definitive diagnosis. In cases in which biopsy histopathological findings were nonspecific, a definitive diagnosis was established on the basis of other diagnostic procedures, such as thoracoscopy, thoracotomy, fiberoptic bronchoscopy, biochemical and cellular measurements in pleural fluid, and/or microbiological tests. The accuracy of CPB was determined with 2 × 2 contingency tables.

RESULTS

A total of 1034 biopsies from patients with pleural effusion were studied. Of those, 171 (16.54%) were excluded from the accuracy analysis either because of inadequate samples or insufficient information. The results of the accuracy analysis were as follows: sensitivity, 77%; specificity, 98%; positive predictive value, 99%; negative predictive value, 66%; positive likelihood ratio, 38.5; negative likelihood ratio, 0.23; pre-test probability, 2.13; and post-test probability, 82.

CONCLUSIONS

CPB is useful in clinical practice as a diagnostic test, because there is an important change from pre-test to post-test probability.

Malignant Pleural Effusion: From Diagnostics to Therapeutics

Malignant pleural effusion is a common complication of cancer and denotes a poor prognosis. It usually presents with dyspnea and a unilateral large pleural effusion. Thoracic computed tomography scans and ultrasound are helpful in distinguishing malignant from benign effusions. Pleural fluid cytology is diagnostic in about 60% of cases. In cytology-negative disease, pleural biopsies are helpful. Current management is palliative. Previously, first-line treatment for recurrent symptomatic malignant pleural effusion was chest drain insertion and talc pleurodesis, with indwelling pleural catheter insertion reserved for patients with trapped lung or failed talc pleurodesis. However, catheter insertion is an increasingly acceptable first-line treatment.

Diagnosis and management of malignant pleural effusions: state of the art in 2017

Malignant pleural effusion (MPE) is a known complication of both thoracic and extra thoracic malignancies. The presence of MPE regardless of the primary site translates into advanced stage disease. Diagnosis and management of MPE with the goals of palliation and improving quality of life poses a challenge for chest physicians. Recently, multiple studies have made attempts to answer questions regarding optimal management in various clinical scenarios. We will review the current evidence and available options for the management of MPE.

The case against performing pleural biopsies for the aetiological diagnosis of exudates

In most cases, the etiological diagnosis of pleural exudates does not require a pleural biopsy. However, when it is considered necessary, the biopsy should seldom be conducted using invasive methods such as thoracoscopy. Two paradigmatic examples are pleural tuberculosis and malignant effusions. In many centres, pleural fluid adenosine deaminase measurement has replaced closed pleural biopsies in the diagnosis of tuberculosis. Similarly, pathological and molecular studies on pleural fluid cell blocks or alternatively, image-guided pleural biopsies have drastically reduced the need for thoracoscopy.

Pleural procedures in the management of malignant effusions

Malignant pleural effusion (MPE) is common in clinical practice, and despite the existence of studies to guide clinical decisions, it often poses diagnostic and therapeutic dilemmas. Once it is diagnosed, median survival does not usually exceed 6 months. The management of these patients focuses on symptom relief since no treatments have been shown to increase survival to date. Conversely, poor management can shorten survival. The approach must be multidisciplinary and allow for individualized care. Initial diagnostic procedures should be minimally invasive and, according to the results and other factors, procedures of increasing complexity will be selecting. Likewise, the treatment of MPEs should be individualized according to factors such as type of tumor, patient functional status, means available, benefits of each procedure, or life expectancy. Currently, treatment seems to tend toward less interventional approaches, in which patients can be managed on an outpatient basis, thus minimizing both the discomfort that more aggressive approaches involve and the costs of care associated with this disease. This article reviews the pleural procedures employed in the management of MPEs with special emphasis on the indication for each one, its usefulness, benefits, and complications.

Role of medical thoracoscopy and closed-blind pleural biopsy in undiagnosed exudative pleural effusions: a single-center experience of 348 patients

BACKGROUND

Medical thoracoscopy (MT) performed either with rigid or the semirigid thoracoscope has been shown to have diagnostic accuracy superior to closed-blind pleural biopsy (CBPB) in exudative pleural effusions (EPE), which remain undiagnosed after thoracentesis. However, in resource-constrained settings, CBPB continues to be performed. In this study, we compare the outcome of thoracoscopy with CBPB.

METHODS

This was a retrospective analysis of data collected over a 10-year period (2004 to 2014) of patients who underwent pleural biopsy for the evaluation of undiagnosed EPE. We report the comparative procedural yield and safety of CBPB and MT.

RESULTS

During the study period, 84 and 264 patients (mean age, 49.8 y) underwent CBPB and MT, respectively. No clinical or radiologic finding could predict the correct histologic diagnosis with reasonable certainty in patients with undiagnosed EPE. The procedural yield of MT was significantly higher than CBPB (93.2% vs. 84.5%, P=0.02). The yield of MT significantly improved when chest ultrasound was used to guide the choice and point of entry of the thoracoscope (98.7% vs. 90.6%, P=0.04). Thoracoscopy was associated with mortality and complication rates of 0.37% and 5.6%, respectively, whereas the complication rate with CBPB was 8.3% with no mortality.

CONCLUSIONS

MT is the procedure of choice in the evaluation of undiagnosed EPE, due to its higher success rate and an acceptable safety profile. However, in centers where thoracoscopy is not feasible, CBPB should be performed in preference to initiating empiric treatment.

Combined evaluation of adenosine deaminase level and histopathological findings from pleural biopsy with Cope's needle for the diagnosis of tuberculous pleurisy

INTRODUCTION

Closed needle pleural biopsy (CNPB) has historically been the gold standard procedure for the diagnosis of pleural tuberculosis. Adenosine deaminase (ADA) is an efficient biomarker for tuberculosis that is measurable in pleural fluids.

OBJECTIVE

We compared the diagnostic accuracy of the pleural ADA (P-ADA) level and histopathological findings of CNPB specimens in patients with pleural tuberculosis.

METHODS

This prospective study consisted of two groups of examinations with a proven diagnosis of pleural effusion. The P-ADA level was measured in 218 patients with pleural effusion due to a number of causes, and 157 CNPB specimens underwent histopathological analysis.

RESULTS

CNPBs were performed in patients with tuberculosis (n=122) and other diseases: adenocarcinoma (n=23), lymphoma (n=5), systemic lupus erythematosus (n=4), squamous cell carcinoma (n=2), and small cell lung cancer (n=1). According to the ROC curve, the optimal cut-off value of the P-ADA level (Giusti and Galanti colorimetric method) was equal to or greater than 40.0 U/L. The diagnostic accuracy of the P-ADA test was 83.0%, and that of histopathological examination of the CNPB tissue, was 78.8% (AUC=0.293, P=0.7695). The association between the P-ADA assay and pleural histopathology was 24.41 (P<0.0001). The tetrachoric correlation coefficient was 0.563 (high correlation).

CONCLUSION

In Brazil and other countries with a high incidence of tuberculosis, P-ADA activity is an accurate test for the diagnosis of tuberculous pleural effusions, and its use should be encouraged. The high diagnostic performance of the P-ADA test could to aid the diagnosis of pleural tuberculosis and render CNPB unnecessary.

Are the days of closed pleural biopsy over? No

Closed pleural biopsy used to be a popular method of evaluation of pleural effusion. With the advent of thoracoscopy, this valuable method is being neglected. Studies have shown that closed pleural biopsy especially done with image guidance has high yield and low complication rate as compared to thoracoscopy. Given the ease of the procedure and the less cost involved, imaged guided closed pleural biopsy should be considered as the initial diagnostic step in undiagnosed pleural biopsy especially in developing countries with high prevalence of tuberculosis.

Tuberculous pleural effusion

Tuberculous pleural effusion (TBPE) is the most common form of extrapulmonary tuberculosis (TB) in Spain, and is one of the most frequent causes of pleural effusion. Although the incidence has steadily declined (4.8 cases/100,000population in 2009), the percentage of TBPE remains steady with respect to the total number of TB cases (14.3%-19.3%). Almost two thirds are men, more than 60% are aged between 15-44years, and it is more common in patients with human immunodeficiency virus. The pathogenesis is usually a delayed hypersensitivity reaction. Symptoms vary depending on the population (more acute in young people and more prolonged in the elderly). The effusion is almost invariably a unilateral exudate (according to Light's criteria), more often on the right side, and the tuberculin test is negative in one third of cases. There are limitations in making a definitive diagnosis, so various pleural fluid biomarkers have been used for this. The combination of adenosine deaminase and lymphocyte percentage may be useful in this respect. Treatment is the same as for any TB. The addition of corticosteroids is not advisable, and chest drainage could help to improve symptoms more rapidly in large effusions.
