ABSTRACT
Malignant pleural effusion (MPE) can occur in nearly all types of malignant tumors, with lung cancer being the most prevalent cause. The presence of MPE indicates an advanced stage or distant spread of the tumor, significantly reducing the patient's life expectancy. Particularly, a substantial amount of pleural effusion can impede heart and lung function, impair blood oxygen perfusion levels in the body, and greatly diminish patients' quality of life. Even when systemic treatment has alleviated the primary lung tumor in some patients, effective control over MPE remains challenging and impacts clinical outcomes. Therefore, it is crucial to implement measures for reducing or managing MPE while ensuring standardized treatment for lung cancer. In recent years, significant advancements have been made in diagnosing and treating lung cancer complicated by MPE through extensive basic and clinical research. Based on existing evidence and China's clinical practice experience, relevant experts from the China Association of Health Promotion and Education and Cancer Rehabilitation and Palliative Treatment Professional Committee of China Anti-Cancer Association (CRPC) have summarized key aspects related to diagnosis and treatment consensus opinions for lung cancer complicated by MPE. This aims to establish standardized procedures that will serve as a reference for doctors' clinical practice.

Introducción: Cerca del 50 % de los derrames pleurales (DP) es neoplásico. El comportamiento clínico del DP neoplásico es altamente sintomático por el gran volumen y su recidiva temprana. Propósito de la revisión: El objetivo de la revisión es delinear el papel de los diferentes métodos diagnósticos y terapéuticos de DP maligno. Buscamos reportes actualizados en donde se incluye los resultados de mejor supervivencia para los distintos tratamientos actuales. Recientes hallazgos: Los criterios de Light es el método estándar para diferenciar un exudado maligno. La toracocentesis guiada por ultrasonido debe ser usada como método diagnóstico/terapéutico. En pacientes con DP maligno se recomienda el drenaje permanente con el posicionamiento de un tubo de tórax y un sello hidráulico con drenaje cerrado. La pleurodesia con instilación de talco está recomendada en pacientes con DP maligno en busca de disminuir el volumen, las recidivas del DP y el tiempo de hospitalización. Conclusiones: Para el correcto manejo del DP maligno, hay que tomar en cuenta varios aspectos, como identificar la presencia de células malignas mediante estudio citológico y descartar una infección. La ecografía pleural permite definir el volumen del DP y permite decidir drenaje en ese momento, con la posibilidad de inserción de catéter intrapleural, con el objetivo de evaluar la posibilidad de esclerosar las pleuras a través de pleurodesia. Sin embargo, para llegar a esta decisión hay que analizar cada uno de los detalles que podrían tener un papel de importancia para el buen manejo y resolución definitiva o por el contrario decidir el manejo a título paliativo, siempre analizando cada caso con el objetivo de proveer de mejoría de síntomas y mejorar la calidad de vida del paciente.
Introduction: Approximately 50% of pleural effusions (PE) are neoplastic. The clinical behavior of neoplastic PE is highly symptomatic due to its large volume and early recurrence. Purpose of review: This review aims to outline the role of the different diagnostic and therapeutic methods of malignant PE. We look for updated reports that include the best survival results for the other current treatments. Recent findings: Light's criteria are the standard to differentiate a malignant exudate. Ultrasound-guided thoracentesis should be used as a diagnostic/therapeutic method. In patients with malignant PE, permanent drainage is recommended with the placement of a chest tube and a hydraulic seal with closed drainage. Pleurodesis with the installation of talc is recommended in patients with malignant PE to reduce volume, PE recurrences, and hospitalization time. Conclusions: For the correct management of malignant PE, several aspects must be considered, such as identifying the presence of malignant cells by cytological study and ruling out infection. Pleural ultrasound allows for defining the volume of the PE. It will enable deciding on drainage at that time, with the possibility of inserting an intrapleural catheter, to evaluate the likelihood of sclerosing the pleurae through pleurodesis. However, to reach this decision, it is necessary to analyze each of the details that could play an essential role in good management and definitive resolution or, on the contrary, decide on palliative management, constantly investigating each case to provide symptom improvement. In addition, improving the patient's quality of life.

Background@#The etiology of pleural effusion remains unclear in nearly 20% of cases. One way to diagnose malignancy is by doing pleural fluid cytology. There are factors that influence the yield of pleural fluid cytology and one of them is appropriate and timely fixation of samples. Currently, there is no local consensus regarding the timing with which the specimen should be fixed.@*Objective@#The study aims to compare the yield of malignancy between early fixation versus usual fixation of pleural fluid samples, meaning there is no set time for fixation to be done.@*Methodology@#The study employed a prospective cross-sectional research design. All patients with pleural effusion who fulfilled the criteria set by the study were included. Two sets of pleural fluid samples were collected amounting to 20cc each. First sample was assigned as Bottle #1 and placed immediately with fixative while the second sample was assigned as Bottle #2. Bottle #2 underwent routine fixation which follows no fixed or standard time of fixation. The time difference between the fixation of two sample groups greatly varied with Bottle #1 fixed immediately right after collection while Bottle#2 depends on the time it will be processed by the laboratory personnel. Both samples were submitted for cell block and cell cytology reading.@*Results@#Characteristics of the 55 patients included in the study showed age group range from 41 to 65 years of age, with 27 male and 28 female patients. Only one third had history of smoking. There were 21.82% who had family history of cancer and with and suspicious mass on chest radiograph. Out of 55 patients, 29 patients had history of previous diagnosis of cancer, 23 had recurrent pleural effusion, and 28 had chest radiograph with suspicious nodules. Based on gross appearance, there were 20 serous and 21 sanguineous pleural fluid noted. Mean cell count was high (1,115.50 ± 741.02) with lymphocytic predominance (82.56 ± 24.46). Elevated protein concentration (5,388.25 ± 8,230.46) and LDH (484.17 ± 248.72) were noted. Glucose (8.78 ± 6.68 mmol/L) was low. There were 21 patients who had high WBC, 24 with high protein and 16 with elevated LDH. There were 3 patients who were positive for AFB and none for KOH. Comparative analysis showed that the pleural fluid samples assigned to the routinely fixed group which were handed to the nurse after thoracentesis, then forwarded to the laboratory through a ward laboratory aide or patient watcherfor fixation with with 95% alcoholby thelaboratory personnel significantly had a longer duration of 406.62 minutes as compared to immediately fixed at 12.27 minutes (P<0.01). For diagnosis of malignancy, significantly more cases were diagnosed in the immediately fixed group with 36.36% cases versus 18.18% (p=0.016).@*Conclusion@#Among patients with suspected malignant pleural effusions, early fixation of pleural fluid samples resulted in higher histopathology yields as compared to those fixed after going through the routine fixation.

OBJECTIVES: We compared the diagnostic potential of cancer ratio (CR, serum lactate dehydrogenase [LDH]/pleural fluid adenosine deaminase [pfADA]), cancer ratio plus (CR plus, cancer ratio/pleural lymphocyte percentage), and age/pfADA ratio with pfADA in malignant pleural effusion. METHODS: Data from 100 patients with malignant pleural effusion (MPE) and 119 patients with tuberculous pleural effusion (TPE) were retrospectively collected. PfADA, age/pfADA ratio, CR, and CR plus were compared between patients with MPE and those with TPE in two age groups (≤50 and >50 years). The best cut-off value was determined, and the diagnostic performance was evaluated according to the receiver operating characteristic curve. RESULTS: PfADA was statistically significantly lower while age/pfADA ratio, CR, and CR plus were significantly higher in the MPE group than in the TPE group in both age groups (p<0.05). For patients aged ≤50 years, the differential diagnostic value of pfADA for MPE was better than those of age/pfADA ratio, CR, and CR plus. At a cut-off value of 13.0 U/L, the sensitivity, specificity, and accuracy were 88.9%, 100.0%, and 98.9%, respectively. For patients aged >50 years, the diagnostic performance of CR plus was superior to those of pfADA, age/pfADA ratio, and CR. At a cut-off value of 22.6, the sensitivity, specificity, and accuracy of CR plus for the diagnosis of MPE were 86.8%, 84.6%, and 86.2%, respectively. CONCLUSIONS: The best parameter for diagnosing MPE was different for patients aged ≤50 years and >50 years. For patients aged >50 years, CR plus was a good parameter for the differential diagnosis of MPE. For patients aged ≤50 years, pfADA was better.

Background: In the West African sub-region, significant morbidity and mortality are known to affect patients with malignant pleural effusion (MPE) but are highly under reported unlike USA, Europe or South Africa. Aim/Objective: To review cases of MPE in our tertiary hospital in the last 13 years with a view to determining the challenges and prospects. Materials and Method: This is a retrospective study spanning over a decade from January, 2007 to December, 2019. Malignant pleural effusion from various neoplasms constitutes the commonest thoracic malignancy in our tertiary hospital. After 13 years of management of such patients, we reviewed the datafrom the hospital record's department. The data obtained were demography, aetiology, total number of pleural fluid specimens for cytology and pleural biopsies submitted for histology, pleurodesis and other treatment modalities. Result: 211 patients with MPE were admitted and managed during the period under review. Of these numbers, 135(64.0%) were confirmed cytologically positive (MPE). 76(36.0%) tested falsely negative and were initially regarded as paramalignant, later confirmed MPE. The age affected was from 7 to 81 years with a mean of 44 years. Of 211 patients with MPE, 94 were males while 117 were females, with a male to female ratio of 4:5. Aetiologically, metastatic breast cancer was the highest followed by advance lung cancer. Conclusion: Submission of insufficient samples resulted in false negative cytology. Review of recurrent pleural effusion and exophytic tumour at the sites of CTTD resulted in late diagnosis of MPE. Additionally, prolonged hospital stay awaiting CTTD and cytology results are among the challenges

RESUMO INTRODUÇÃO: O derrame pleural neoplásico é caracterizado pelo acúmulo anormal de líquido com células malignas no espaço pleural. Pode ser assintomático porém, seu principal sintoma é a dispneia. As causas mais frequentes de neoplasias com derrame pleural maligno são: carcinoma broncogênico, neoplasia mamária, mesotelioma, linfoma de Hodgkin, leucemias, tumores de ovário e carcinomas do trato digestivo. OBJETIVO: Realizar uma revisão da literatura sobre os derrames pleurais neoplásicos e o uso da pleurodese como opção de tratamento. MÉTODO: Foi realizada revisão da literatura, retrospectiva, com os dados coletados entre os meses de maio a agosto de 2019, utilizando as palavras-chave "pleurodese", "derrame pleural neoplásico" e "talco" no portal de periódicos da CAPES e na Cochrane. Revisado 39 artigos dos quais foram incluídos 14 artigos publicados nos últimos 15 anos. DISCUSSÃO: Para os casos inéditos de derrame pleural maligno e sintomático, deve-se realizar toracocentese de alívio. A pleurodese está indicada em pacientes sintomáticos, com derrame de repetição e expansão pulmonar adequada. O talco é o agente esclerosante de escolha na realização da pleurodese, devido seu baixo custo, disponibilidade, fácil administração, poucas complicações e boa efetividade. Atualmente, o talco é aplicado por toracoscopia ou pelo dreno, neste caso, sob a forma do talco "slurry" (suspensão de talco). O talco slurry é a forma de escolha, quando comparado ao talco em pó, pois apresenta menos efeitos colaterais, com eficácia semelhante. CONCLUSÃO: A pleurodese em derrame neoplásicos se destina à remissão dos sintomas, com melhora da qualidade de vida. Não tem efeito no prognóstico do paciente e aumento de sua sobrevida.

To analyze the components of tumor infiltrating T lymphocyte (TIL) cells in malignant pleural effusion of lung adenocarcinoma, and evaluate their killing activities to autologous tumor cells. Methods: Malignant pleural effusions were collected from 17 patients with lung adenocarcinoma. Mononuclear cells were isolated by Ficoll density gradient centrifugation and flow cytometer was used to analyze TIL cell components. TIL and tumor cells were separated through adherent culture. The tumor cells were identified via intramuscular injection of adherent cells into nude mice and the killing effect of cultured lymphocytes on autologous tumor cells was studied. Results: Of the TIL in malignant pleural effusions, T cells accounted for 60.6%-79.3%, while T helper cells were significantly higher than T killer cells (36.63%±1.90% vs 24.64%±2.32%, P<0.001). There were also natural killer (NK) cells and NK T cells in the effusions. Tumor cells were successfully isolated and cultured. The killing activity of cultured TIL to autologous tumor cells was 39.14%±12.04%, and the killing activity of TIL with high proliferation rate to autologous tumor cells was higher than that of low proliferation group (50.51%±3.80% vs 29.04%±5.77%, P<0.001). Conclusion: T lymphocytes are the major components of TIL in malignant pleural effusions derived from lung adenocarcinoma, and T helper cells are more than T killer cells. The killing activity of TIL with strong proliferation ability to autologous tumor cells is higher than that of TIL with weak proliferation ability. Therefore, cells from malignant pleural effusions could be used for cellular immunotherapy against tumor.

OBJECTIVE@#To study the clinical value of detecting carcinoembryonic antigen levels in pleural effusion (PCEA) and serum (SCEA) and their ratio (P/S) in the differential diagnosis of pleural effusions resulting from tuberculosis and lung cancer.@*METHODS@#This retrospectively study was conducted among 82 patients with pleural effusion caused by pulmonary tuberculous (TB; control group) and 120 patients with pleural effusion resulting from lung cancer in our hospital between April, 2016 and March, 2018. PCEA, SCEA and P/S were compared between the two groups and among the subgroups of lung cancer patients with squamous cell carcinoma (SqCa), adenocarcinoma (ACA), small cell carcinoma (SCLC). The receiveroperating characteristic curve (ROC) analysis was used to confirm the optimal critical value to evaluate the diagnostic efficiency of different combinations of PCEA, SCEA and P/S.@*RESULTS@#PCEA, SCEA and P/S were significantly higher in the overall cancer patients and in all the 3 subgroups of cancer patients than in the patients with TB ( < 0.05). The areas under the ROC curve of PCEA, SCEA and P/S were 0.925, 0.866 and 0.796, respectively; PCEA had the highest diagnostic value, whose diagnostic sensitivity, specificity, accurate rate, and diagnostic threshold were 83.33%, 96.34, 88.61%, and 3.26 ng/ml, respectively; SCEA had the lowest diagnostic performance; the diagnostic performance of P/S was between that of SCEA and PCEA, but its combination with SCEA greatly improved the diagnostic performance and reduced the rates of misdiagnosis and missed diagnosis. Parallel tests showed that the 3 indexes combined had significantly higher diagnostic sensitivity than each or any two of the single indexes ( < 0.05), but the diagnostic specificity did not differ significantly. The area under the ROC curve of combined detections of the 3 indexes was 0.941 for diagnosis of lung cancer-related pleural effusion, higher than those of any other combinations of the indexes.@*CONCLUSIONS@#The combined detection of PCEA, SCEA and P/S has a high sensitivity for diagnosis of lung cancer-related pleural effusion and provides important information for rapid and accurate diagnosis of suspected cases.

Lung cancer is the most commonly diagnosed cancer worldwide. Malignant pleural effusion (MPE) caused by advanced lung cancer seriously affect the patients' quality of life and prognosis. The management of MPE includes thoracentesis, pleurodesis, indwelling pleural catheters and drug perfusion in pleural cavity. Vascular endothelial growth factor (VEGF) and its receptor are a group of important ligands and receptors that affect angiogenesis. They are the main factors controlling angiogenesis, and they play an important role in the formation of MPE. Bevacizumab is a recombinant humanized VEGF monoclonal antibody, competitively binding to endogenous VEGF receptor. Bevacizumab can inhibit new blood vessel formation, reduce vascular permeability, prevent pleural effusion accumulation and slow the growth of cancers. This review aims to discuss the progress of bevacizumab in the treatment of MPE caused by non-small cell lung cancer (NSCLC), and explore the clinical application, efficacy, safety and future direction of bevacizumab. .

Summary Objective: The current study aimed to investigate the clinical efficacy of paclitaxel combined with avastin for non-small cell lung cancer (NSCLC) patients diagnosed with malignant pleural effusion (MPE). Method: Total of 33 patients diagnosed with NSCLC as well as malignant pleural effusion were included. All of them received paclitaxel (175 mg/m2) and avastin (5 mg/kg). Clinical efficacy was evaluated using the total response rate, overall survival, progression-free survival and changes in MPE volume. Adverse events and rates of toxicities were examined as well. Results: The total response rate reached 77% while the overall survival and the median progression-free survival were respectively 22.2 months and 8.4 months. Toxicities of grade 3-4 consisted of neutropenia in 57% of patients, anemia in 17% of them, febrile neutropenia in 11%, as well as anorexia in 7%. No treatment-correlated deaths were found. Conclusion: Paclitaxel combined with avastin decreased MPE volume and increased survival rate of NSCLC patients via inhibiting vascular endothelial growth factor expression.

We present a case of 55-year-old man who complained of dyspnea and sputum for a month. He was an ex-smoker with a history of prostate cancer and pulmonary tuberculosis. Chest radiographs revealed bilateral pleural effusions of a small to moderate amount. Pigtail catheters were inserted for drainage. The pleural fluid consisted of large clusters and tightly cohesive groups of malignant cells, which however could not be ascribed to prostate cancer with certainty. We performed immunocytochemical panel studies to determine the origin of cancer metastasis. The immunostaining results were positive for prostate-specific antigen, alpha-methylacyl-coenzyme A racemase, and Nkx 3.1, consistent with prostate cancer. Pleural effusion associated with prostate cancer is rare. To our knowledge, this is the first case report in Korea to describe cytologic features of malignant pleural effusion associated with prostate cancer.

Chest tube insertion is a common procedure usually done for the purpose of draining accumulated air or fluid in the pleural cavity. Small-bore chest tubes (≤14F) are generally recommended as the first-line therapy for spontaneous pneumothorax in non-ventilated patients and pleural effusions in general, with the possible exception of hemothoraces and malignant effusions (for which an immediate pleurodesis is planned). Large-bore chest drains may be useful for very large air leaks, as well as post-ineffective trial with small-bore drains. Chest tube insertion should be guided by imaging, either bedside ultrasonography or, less commonly, computed tomography. The so-called trocar technique must be avoided. Instead, blunt dissection (for tubes >24F) or the Seldinger technique should be used. All chest tubes are connected to a drainage system device: flutter valve, underwater seal, electronic systems or, for indwelling pleural catheters (IPC), vacuum bottles. The classic, three-bottle drainage system requires either (external) wall suction or gravity (“water seal”) drainage (the former not being routinely recommended unless the latter is not effective). The optimal timing for tube removal is still a matter of controversy; however, the use of digital drainage systems facilitates informed and prudent decision-making in that area. A drain-clamping test before tube withdrawal is generally not advocated. Pain, drain blockage and accidental dislodgment are common complications of small-bore drains; the most dreaded complications include organ injury, hemothorax, infections, and re-expansion pulmonary edema. IPC represent a first-line palliative therapy of malignant pleural effusions in many centers. The optimal frequency of drainage, for IPC, has not been formally agreed upon or otherwise officially established.

Spontaneous regression of metastatic renal cell carcinoma (mRCC) was reported over the last century. However, there are no reports on spontaneous regression of mRCC by talc pleurodesis. A 43-year-old man who underwent left nephrectomy by RCC visited emergency room with headache and hallucination. Tumor was metastasized to brain, lung, and pleura accompanied by malignant pleural effusion. Talc pleurodesis by video-assisted thoracoscopic surgery was performed to treat malignant pleural effusion. After 7 months without specific chemotherapy, pulmonary lesions of mRCC gradually regressed. We thought that this phenomenon appears as an immunologic response of talc pleurodesis. We herein present a rare case of spontaneous regression of mRCC following talc pleurodesis. To the best of our knowledge, this is the first case of spontaneous regression in mRCC following talc pleurodesis.

PURPOSE: Malignant pleural effusions (MPEs) are often observed in lung cancer, particularly adenocarcinoma. The aim of this study was to investigate epidermal growth factor receptor (EGFR) mutation status in lung adenocarcinoma-associated MPEs (LA-MPEs) and its correlation with efficacy of EGFR tyrosine kinase inhibitor (TKI) therapy. MATERIALS AND METHODS: Samples comprised 40 cell blocks of pathologically-confirmed LA-MPEs collected before the start of EGFR TKI therapy. EGFR mutation status was re-evaluated by peptide nucleic acid clamping and the clinical outcomes of EGFR TKI-treated patients were analyzed retrospectively. RESULTS: EGFR mutations were detected in 72.5% of LA-MPE cell blocks (29/40). The median progression-free survival for patients with EGFR mutations in LA-MPEs was better than that for patients with wild-type EGFR (7.33 months vs. 2.07 months; hazard ratio, 0.486; 95% confidence interval, 0.206 to 1.144; p=0.032). The objective response rate (ORR) of 26 patients with EGFR mutations in LA-MPEs among the 36 patients with measurable lesions was 80.8%, while the ORR of the 10 patients with wild-type EGFR in LA-MPEs was 10% (p < 0.001). Among the 26 patients with EGFR mutations in LA-MPEs, the ORR of target lesions and LA-MPEs were 88.5% and 61.5%, respectively (p=0.026). CONCLUSION: EGFR mutation status in cell blocks of LA-MPEs confirmed by pathologic diagnosis is highly predictive of EGFR TKI efficacy. For patients with EGFR mutations in LA-MPEs, the response to EGFR TKIs seems to be worse for pleural effusions than for solid tumors.

BACKGROUND@#Malignant pleural effusion (MPE) refers to pleural effusion which arises from primary malignant tumor of pleura or other pleural metastatic tumors. Injection of elemene in chest makes good effect on the treatment of MPE, and is widely used in clinic. Adverse effects also exist, but the severe adverse effects and relevant managements are rarely reported. The aim of this study is to observe the adverse reactions induced by the treatment of malignant pleural effusion through elemene injection and to explore the solutions.@*METHODS@#A retrospective analysis was made on 14 cases of patients receiving intra-pleural injections with elemene, and the incidence of severe adverse reactions of 7 cases were disscussed in detail.@*RESULTS@#Most of the severe adverse reactions caused by elemene were severe chest pain, dyspnea, wheezing, clouding of consciousness and coagulopathy.@*CONCLUSIONS@#Strict screening, full preprocessing and close monitoring are necessary to prevent serious adverse reactions caused by elemene injection in the treatment of malignant pleural effusion.
