Abstract
Cholangiocarcinoma is an aggressive and heterogeneous malignancy originating from the bile duct epithelium. It is associated with poor prognosis and high mortality. The global incidence of cholangiocarcinoma is rising, and there is an urgent need for effective early diagnosis and treatment strategies to reduce the burden of this devastating tumor. Small extracellular vesicles, including exosomes and microparticles, are nanoscale vesicles formed by membranes that are released both normally and pathologically from cells, mediating the intercellular transfer of substances and information. Recent studies have demonstrated the involvement of small extracellular vesicles in numerous biological processes, as well as the proliferation, invasion, and metastasis of tumor cells. The present review summarizes the tumorigenic roles of small extracellular vesicles in the cholangiocarcinoma microenvironment. Owing to their unique composition, accessibility, and stability in biological fluids, small extracellular vesicles have emerged as ideal biomarkers for use in liquid biopsies for diagnosing and outcome prediction of cholangiocarcinoma. Specific tissue tropism, theoretical biocompatibility, low clearance, and strong biological barrier penetration of small extracellular vesicles make them suitable drug carriers for cancer therapy. Furthermore, the potential value of small extracellular vesicle-based therapies for cholangiocarcinoma is also reviewed.

Impact of thoracic tumor radiotherapy on survival in non-small-cell lung cancer with malignant pleural effusion treated with targeted therapy: Propensity score matching study. Cancer Med 2023; 12:14949-14959. [PMID: 37288833 PMCID: PMC10417183 DOI: 10.1002/cam4.6130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 05/11/2023] [Accepted: 05/14/2023] [Indexed: 06/09/2023] Open
Abstract
BACKGROUND EGFR-mutant (EGFR-M) and ALK-positive (ALK-P)are common in malignant pleural effusion (MPE) with metastatic non-small-cell lung cancer (NSCLC) (MPE-NSCLC). The impact of thoracic tumor radiotherapy on survival in such patients remains unclear. We aimed to investigate whether thoracic tumor radiotherapy could improve overall survival (OS) in such patients. METHODS According to whether or not patients accepted thoracic tumor radiotherapy, 148 patients with EGFR-M or ALK-P MPE-NSCLC treated with targeted therapy were classified into two groups: DT group without thoracic tumor radiotherapy and DRT group with thoracic tumor radiotherapy. Propensity score matching (PSM) was performed to balance clinical baseline characteristics. Overall survival was analyzed by Kaplan-Meier, compared by log-rank test, and evaluated using Cox proportional hazards model. RESULTS Median survival time (MST) was 25 months versus 17 months in the DRT group and DT group. The OS rates at 1, 2, 3, 5 years in the DRT group and DT group were 75.0%, 52.8%, 26.8%, 11.1% and 64.5%, 28.4%, 9.2%, 1.8%, respectively (χ2 = 12.028, p = 0.001). Compared with DT group, the DRT group still had better survival after PSM (p = 0.007). Before and after PSM, factors associated with better OS through multivariable analysis were that thoracic tumor radiotherapy, radiotherapy, N0-2 , and ALK-TKIs. Grades 4-5 radiation toxicities were not observed in patients; 8 (11.6%) and 7 (10.1%) out of the DRT group suffered from Grade 3 radiation esophagitis and radiation pneumonitis, respectively. CONCLUSION Our results for EGFR-M or ALK-P MPE-NSCLC showed that thoracic tumor radiotherapy may be crucial factor in improving OS with acceptable toxicities. Potential biases should not be neglected: Further randomized controlled trials are necessary to confirm this result.

Abstract
Purpose Actionable mutations are common in non-small cell lung cancer(NSCLC)with malignant pleural effusion(MPE)(MPE-NSCLC). The pattern of failure in MPE-NSCLC treated with targeted therapy after MPE control remains unclear. We aimed to investigate the failure pattern of such patients in a cohort study and explore the possibility of radiotherapy. Patients and methods Computed tomography scans of 86 patients were reviewed in this study. We classified first pattern of failure after MPE control as initial disease sites only (IF), new distant sites only (NF), or IF and NF detected simultaneously (INF). Patients evaluated suitable for radiotherapy after disease progression were divided into two groups: D group without radiotherapy and RD group with radiotherapy. The Kaplan-Meier method and log-rank test were used for survival analyses. Results Disease progression after MPE control was observed in 42 patients with complete serial imaging. Median time to any progression was 9.5 months. Rate of the IF, NF and INF were 50%, 17% and 33% for all patients,60%,0% and 40% for patients with MPE recurrence (n=10,23.8%) and 47%, 22% and 31% for patients (n=32,76.2%) without MPE recurrence, respectively. Out of 10 patients(23.8%) with MPE recurrence, 7 patients simultaneous underwent primary tumor progression and 5 MPE were cytologically confirmed in 7 patients with examination. The overall survival (OS )rates at 1, 2, 3 years for the RD group and D group were 88.2%, 50.5%, 21.7% and 80.0%, 20.3%, 0%, respectively; the corresponding MST were 26.1 months and 17.5 months, respectively (χ2 = 4.959, p =0.026). Conclusions Our data indicates that 50% of patients with actionable mutations MPE- NSCLC after MPE control are likely to fail at their initial sites of disease and the use of radiotherapy may bring OS benefits during the course of their disease. Multicenter RCT is necessary to confirm the result in the future.

Life (Basel) 2023; 13:life13051163.

Abstract
Malignant pleural effusion is associated with a poor prognosis and, while risk stratification models exist, prior studies have not evaluated pleural fluid resolution and its association with survival. We performed a retrospective review of patients diagnosed with malignant pleural effusion between 2013 and 2017, evaluating patient demographics, pleural fluid and serum composition, and procedural and treatment data using Cox regression analysis to evaluate associations with survival. In total, 123 patients were included in the study, with median survival from diagnosis being 4.8 months. Resolution of malignant pleural fluid was associated with a significant survival benefit, even when accounting for factors such as placement of an indwelling pleural catheter, anti-cancer therapy, pleural fluid cytology, cancer pheno/genotypes, and pleural fluid characteristics. Elevated fluid protein, placement of an indwelling pleural catheter, and treatment with targeted or hormone therapies were associated with pleural fluid resolution. We conclude that the resolution of pleural fluid accumulation in patients with malignant pleural effusion is associated with a survival benefit possibility representing a surrogate marker for treatment of the underlying metastatic cancer. These findings support the need to better understand the mechanism of fluid resolution in patients with malignant pleural effusion as well as the tumor-immune interplay occurring with the malignant pleural space.

Effect of chemotherapy, immunotherapy, and targeted therapies on removal of indwelling pleural catheters in non-small cell lung cancer patients with malignant pleural effusions. Respir Med 2023; 206:107093. [PMID: 36549515 DOI: 10.1016/j.rmed.2022.107093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 11/27/2022] [Accepted: 12/18/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Indwelling pleural catheters (IPCs) are a mainstay therapy for malignant pleural effusions (MPEs). Many patients treated with IPCs achieve pleurodesis. We aimed to identify the effect of systemic therapies for non-small cell lung cancer (NSCLC) on IPC removal in patients with associated MPEs. METHODS We completed a retrospective cohort study of adult IPC recipients with metastatic NSCLC at the pleural effusion clinic at the Royal Alexandra Hospital from 2009 to 2020. We used logistic regression to assess the rates of IPC removal and Cox regression to assess the time to IPC removal. RESULTS 232 patients met inclusion criteria with 248 IPCs reviewed. The overall pleurodesis rate was 42.7% with a median time to pleurodesis of 68 (IQR 38-140) days. In univariate analysis, chemotherapy (OR 1.86, CI 0.99-3.49) and epidermal growth factor receptor (EGFR) targeted therapy (OR 3.81, CI 1.86-7.79) were associated with higher rates of pleurodesis. In multivariate analysis, increased rates of pleurodesis were associated with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of ≤2 (OR 4.82, CI 2.24-10.37) and EGFR targeted therapy (OR 3.87, CI 1.80-8.32). Earlier IPC removal was associated with EGFR targeted therapy in both univariate (HR 1.84, CI 1.20-2.83) and multivariate analysis (HR 1.86, CI 1.19-2.92). CONCLUSIONS Treatment with EGFR targeted therapy is associated with increased rates and earlier removal of IPC in patients with NSCLC in our cohort. Further large cohort studies are required to determine if this relationship persists.

[PMID: 36493600 PMCID: PMC9808475 DOI: 10.1016/j.esmoop.2022.100742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 09/30/2022] [Accepted: 11/05/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Anaplastic lymphoma kinase-positive (ALK+) and ROS proto-oncogene 1 (ROS1)-positive (ROS1+) lung cancers have been reported to be associated with an elevated risk of thromboembolic events. This study aimed to assess the long-term risk of developing thromboembolism (TE) in ROS1+ lung cancer and to compare it with other oncogenic drivers in the Asian population. MATERIALS AND METHODS We retrospectively enrolled a cohort of ROS1+ lung adenocarcinoma in a medical center in Taiwan and a comparison cohort of ALK+ and epidermal growth factor receptor-positive (EGFR+) lung cancers. Venous and arterial TEs were identified throughout the cancer course, and the incidence rate was calculated. RESULTS We enrolled 44 ROS1+, 98 ALK+, and 168 EGFR+ non-small-cell lung cancer (NSCLC) patients. A total of 11 (25%), 36 (36.7%), and 38 (22.6%) patients in the ROS1, ALK, and EGFR cohorts, respectively, were diagnosed with thromboembolic events throughout the follow-up course of the disease (P = 0.042). The incidence rates were 99.0, 91.9, and 82.5 events per 1000 person-years for the ROS1, ALK, and EGFR cohorts, respectively. The majority of thrombosis events in the ROS1 (91.6%) and ALK (85.4%) cohorts were venous. On the contrary, 43.2% of thromboembolic events were arterial in the EGFR cohort. A higher proportion of thromboembolic events were noted during cancer diagnosis in the ROS1 cohort (36.3%) than in the ALK (16.7%) and EGFR (10.5%) cohorts. The stage was the only clinical variable associated with thromboembolic risk. There was a significant difference in survival between patients with and without TE in the EGFR cohort, but not in the ALK and ROS1 cohorts. CONCLUSIONS Although ROS1+ and ALK+ NSCLCs had a higher cumulative incidence of TE than EGFR+ NSCLC, the person-year incidence rates were similar among the three groups. EGFR-mutated NSCLC had more arterial events. Nevertheless, ALK+ lung cancer had higher venous events than EGFR-mutated lung cancer.

Abstract
PURPOSE The impact of primary tumour radiotherapy on the prognosis for non-small-cell lung cancer (NSCLC) with controlled malignant pleural effusion (MPE-C) (MPE-C-NSCLC) is unclear. This study aimed to analyze the efficacy and safety of primary tumor radiotherapy in patients with MPE-C-NSCLC. PATIENTS AND METHODS A total of 186 patients with MPE-C-NSCLC were enrolled and divided into two groups. The patients in the D group were treated with only drugs. Those in the RD group were treated with drugs plus primary tumour radiotherapy. The Kaplan-Meier method was used for survival analysis, and the Log rank test was used for between-group analysis and univariate prognostic analysis. The Cox proportional hazards model was used to perform multivariate analyses to assess the impacts of factors on survival. Propensity score matching (PSM) was matched based on clinical characteristics, systematic drug treatment and drug response to further adjust for confounding factors. RESULTS The overall survival (OS) rates at 1, 2, and 3 years for the RD group and D group were 54.4%, 26.8%, and 13.3% and 31.1%, 11.5%, and 4.4%, respectively; the corresponding MSTs were 14 months and 8 months, respectively (χ 2=15.915, p<0.001). There was a significant difference in survival by PSM (p=0.027).Before PSM, multivariate analysis showed that metastasis status (organ≤3 and metastasis≤5), primary tumour radiotherapy, chemotherapy cycles≥4, and drug best response (CR+PR) were independent predictors of prolonged OS. After PSM, primary tumour radiotherapy and drug best response (CR+PR) were independent predictors of prolonged OS were still independent predictors of prolonged OS. There were no grade 4-5 radiation toxicities. CONCLUSION For MPE-C-NSCLC, the response of systemic drug treatment plays a crucial role in survival outcomes, and we also should pay attention to primary tumour radiotherapy in addition to systematic drug treatment.

Abstract
Vesicles, also known as "microparticles", are vesicle-like structures that are released outside the cell in a "sprouting" manner when the cytoskeleton is changed during cell activation or apoptosis, with a diameter of about 100-1000 nm, and are carriers of material information exchange between cells. Tumor-derived extracellular vesicles can effectively deliver drugs to the nucleus of tumor stem cells, thus effectively killing them without toxic side effects. The underlying mechanism involves the soft nature of tumor stem cells that allows better uptake of vesicles, and the entry of drug-carrying vesicles into lysosomes and facilitation of lysosomal movement toward the nucleus to deliver drugs to the nucleus. Drug-loaded vesicles have unique advantages, such as low immunogenicity, homing targeting ability, and the ability to break through the physiological barrier to tumor therapy. Tumor-derived drug-delivery vesicles have entered clinical trials for the treatment of malignant pleural effusions. In this review, we summarized the progress of basic and clinical research on tumor cell-derived drug-loaded vesicles for the treatment of malignant pleural effusion in recent years.

Interactions between EGFR and EphA2 promote tumorigenesis through the action of Ephexin1. Cell Death Dis 2022; 13:528. [PMID: 35668076 PMCID: PMC9170705 DOI: 10.1038/s41419-022-04984-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 05/24/2022] [Accepted: 05/26/2022] [Indexed: 02/07/2023]
Abstract
The cell signaling factors EGFR, EphA2, and Ephexin1 are associated with lung and colorectal cancer and play an important role in tumorigenesis. Although the respective functional roles of EGFR and EphA2 are well known, interactions between these proteins and a functional role for the complex is not understood. Here, we showed that Ephexin1, EphA2, and EGFR are each expressed at higher levels in lung and colorectal cancer patient tissues, and binding of EGFR to EphA2 was associated with both increased tumor grade and metastatic cases in both cancer types. Treatment with Epidermal Growth Factor (EGF) induced binding of the RR domain of EGFR to the kinase domain of EphA2, and this binding was promoted by Ephexin1. Additionally, the AKT-mediated phosphorylation of EphA2 (at Ser897) promoted interactions with EGFR, pointing to the importance of this pathway. Two mutations in EGFR, L858R and T790M, that are frequently observed in lung cancer patients, promoted binding to EphA2, and this binding was dependent on Ephexin1. Our results indicate that the formation of a complex between EGFR, EphA2, and Ephexin1 plays an important role in lung and colorectal cancers, and that inhibition of this complex may be an effective target for cancer therapy.

Abstract
Extracellular vesicles (EVs), spherical biological vesicles, mainly contain nucleic acids, proteins, lipids and metabolites for biological information transfer between cells. Microparticles (MPs), a subtype of EVs, directly emerge from plasma membranes, and have gained interest in recent years. Specific cell stimulation conditions, such as ultraviolet and X-rays irradiation, can induce the release of MPs, which are endowed with unique antitumor functionalities, either for therapeutic vaccines or as direct antitumor agents. Moreover, the size of MPs (100–1000 nm) and their spherical structures surrounded by a lipid bilayer membrane allow MPs to function as delivery vectors for bioactive antitumor compounds, with favorable phamacokinetic behavior, immunostimulatory activity and biological function, without inherent carrier-specific toxic side effects. In this review, the mechanisms underlying MP biogenesis, factors that influence MP production, properties of MP membranes, size, composition and isolation methods of MPs are discussed. Additionally, the applications and mechanisms of action of MPs, as well as the main hurdles for their applications in cancer management, are introduced.

Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide, yet most currently used in vitro cancer models are confined to traditional 2D cell culture conditions. Recently; however, innovative 3D models such as tumor tissue equivalents (organoids) have been adopted by researchers to recapitulate tissue architecture and physiology in order to improve disease modeling and drug testing. We have hypothesized that 3D lung organoids, incorporating cells directly from patients, will enable personalized disease modeling and tumor cell characterization compared to traditional 2D cultures. Here, we discuss the fabrication of 3D lung cancer organoids using a rare cell source, pleural effusion aspirate. We tracked the phenotypic change that developed in short-term culturing and characterized the cell population within the organoids. We found that isolated patient cells embedded directly into organoids created anatomically relevant structures and displayed lung cancer specific behaviors compared to cultures that first grew in 2D conditions. Additionally, we compared responses of patient cells from pleural effusion aspirates to chemotherapy in 2D and 3D cell culture systems. Our results show that cells in 2D cultures are more sensitive to treatment when compared with 3D organoids. Collectively, we have been able to isolate tumor cells from pleural effusion fluid of lung cancer patients and create organoids that display in vivo like anatomy and drug response. This technology can serve as a more accurate disease model for studying tumor progression and drug development.

Abstract
The exact role of pleural effusion in the prognosis of cancer patients remains unclear. We aimed to systematically review the prognostic value of pleural effusion in patients with cancer. We performed a systematic review and meta‐analysis with a systematic literature search. All cohort studies with available overall survival (OS) and progression‐free survival (PFS) results for patients with cancer with or without pleural effusion were included. The Mantel–Haenszel method was used to calculate the pooled hazard ratios (HRs) and 95% confidence intervals (CIs). Heterogeneity and publication bias were examined. Subgroup analysis and sensitivity analysis were performed. A total of 47 studies with 146,117 patients were included in the analysis. For OS, pleural effusion was a prognostic factor associated with a poor prognosis for patients with cancer (HR, 1.58, 95% CI, 1.43–1.75; I2 94.8%). In the subgroup analysis, pleural effusion was a prognostic factor associated with poor survival for patients with lung cancer (HR, 1.44, 95% CI, 1.35–1.54; I2 60.8%), hematological cancer (HR, 2.79, 95% CI, 1.63–4.77; I2 29.4%) and other types of cancer (HR, 2.08, 95% CI, 1.43–3.01; I2 55.1%). For PFS, pleural effusion was a prognostic factor associated with a poor prognosis for patients with cancer (HR, 1.61, 95% CI, 1.28–2.03; I2 42.9%). We also observed that massive pleural effusion was a prognostic factor associated with a poorer prognosis compared to minimal pleural effusion. Pleural effusion had prognostic value in both OS and PFS of patients with cancer, except for patients with malignant pleural mesothelioma, regardless of whether the malignant effusion was confirmed histologically or cytologically. However, future evidence of other pleural effusion characteristics is still needed.

Abstract
BACKGROUND AND OBJECTIVE Prognostication of malignant pleural effusion (MPE) guides treatment strategies but existing prognostication scores are yet to be validated in Asians. We aimed to evaluate the performance of these scores in an Asian population. A refined score was also proposed based on the impact of EGFR mutation on survival. METHODS Survival and clinical data of histocytologically-confirmed MPE patients from a Hong Kong hospital were analyzed with the LENT, modified-LENT, PROMISE and SELECT (converted from its original model) scores. A refinement of the LENT score for Asians was proposed by inclusion of EGFR status (EGFR-LENT), which was compared with the LENT score and validated in an independent patient cohort. RESULTS All prognostication scores performed well on risk stratification by Kaplan-Meier curve (log rank p < 0.0001) in 368 MPE patients except for LENT in low-risk group. C-statistics for LENT, modified LENT, PROMISE and SELECT in predicting 3-month mortality were 0.77, 0.80, 0.80 and 0.82, respectively. The proposed LENT score refinement (EGFR-LENT) improved stratification among low-risk patients; with a higher C-statistic (0.83) in 3-month mortality prediction than LENT (0.77, p = 0.0121), PROMISE (0.80, p = 0.3713), and SELECT (0.82, p = 0.7908) scores. Validation of EGFR-LENT in an independent cohort (124 patients) confirmed good performance in predicting 3-month mortality (C-statistic 0.87, vs 0.79 in LENT, p = 0.0444). CONCLUSION All existing scores had reasonable performance in prognosticating MPE, and LENT score refinement by inclusion of EGFR mutation status improved its performance among Asian MPE patients.

Abstract
Background Malignant pleural effusion (MPE) portends a poor prognosis in non-small cell lung cancer (NSCLC). However, the yield of pleural fluid cytology as well as survival of patients with MPE associated with squamous cell carcinoma versus adenocarcinoma is not well understood. We conducted this study to assess the diagnostic yield of pleural cytology and survival of patients with NSCLC related MPE. Methods We performed a single-center, retrospective analysis of patients with NSCLC related MPE between 2010 and 2017. Kaplan-Meier method was used to compare survival and Cox proportional hazards analysis to assess if squamous cell cytopathology was associated with mortality. Results We identified 277 patients, 29 with squamous cell and 248 with adenocarcinoma MPE. Pleural fluid cytology from initial thoracentesis was diagnostic in 13.8% (4/29) patients with squamous cell and 80.2% (199/248) with adenocarcinoma (P<0.001). Cytology from second thoracentesis was diagnostic in 13.3% (2/15) patients with squamous cell carcinoma, compared to 37.5% (12/32) with adenocarcinoma (P=0.17). There was no statistically significant difference in the pleural biopsy yield from medical pleuroscopy or video-assisted thoracoscopic surgery (VATS) in the two groups. The median survival of patients with squamous cell MPE was 112 [interquartile range (IQR): 44-220] days versus 194 (IQR: 54-523) days in adenocarcinoma (Log-rank test P=0.04). Multivariate Cox proportional hazards analysis showed that squamous cell cytopathology was independent predictor of mortality (hazard ratio for death of 1.73, 95% CI: 1.1-2.6; P=0.01). Conclusions Pleural fluid cytology has a low diagnostic yield in squamous cell carcinoma MPE, and these patients have a poor survival compared to lung adenocarcinoma.

Abstract
Lung cancer is the leading cause of cancer‐related death worldwide. As well as the identified role of epidermal growth factor receptor (EGFR), its association with driver mutations has improved the therapeutics for patients with lung cancer harboring EGFR mutations. These patients usually display shorter overall survival and a higher tendency to develop distant metastasis compared with those carrying the wild‐type EGFR. Nevertheless, the way to control mutated EGFR signaling remains unclear. Here, we performed membrane proteomic analysis to determine potential components that may act with EGFR mutations to promote lung cancer malignancy. Expression of transmembrane glycoprotein non‐metastatic melanoma protein B (GPNMB) was positively correlated with the status of mutated EGFR in non‐small‐cell lung cancer (NSCLC). This protein was not only overexpressed but also highly glycosylated in EGFR‐mutated, especially EGFR‐L858R mutated, NSCLC cells. Further examination showed that GPNMB could activate mutated EGFR without ligand stimulation and could bind to the C‐terminus of EGFR, assist phosphorylation at Y845, turn on downstream STAT3 signaling, and promote cancer metastasis. Moreover, we also found that Asn134 (N134) glycosylation of GPNMB played a crucial role in this ligand‐independent regulation. Depleting N134‐glycosylation on GPNMB could dramatically inhibit binding of GPNMB to mutated EGFR, blocking its downstream signaling, and ultimately inhibiting cancer metastasis in NSCLC. Clarifying the role of N‐glycosylated GPNMB in regulating the ligand‐independent activation of mutated EGFR may soon give new insight into the development of novel therapeutics for NSCLC.

Abstract
Background Malignant pleural effusion (MPE) is usually caused by lung cancer, and the prognostic factors are poorly understood. We aimed to develop models to predict the survival of lung cancer patients and lung adenocarcinoma patients with MPE. Methods We enrolled lung cancer patients with MPE in Nanjing Jinling Hospital from January 2008 to June 2018 into our study. We selected risk factors using multivariable Cox proportional-hazards analysis in the development cohort. The risk models were created according to the risk ratio (RR) value. The participants were categorized into low-risk, moderate-risk, and high-risk groups according to the sum of every risk factor. Results A total of 367 lung cancer patients were included in the development cohort. The scoring systems RECLS (relapse or not, ECOG PS, CRP, pleural LDH, and TNM stage) and RECLSAM (relapse or not, ECOG PS, CRP, pleural LDH, TNM stage, albumin-globulin ratio, and activating gene mutation) were created for lung cancer patients with MPE and lung adenocarcinoma patients with MPE. The area under the curve (AUC) values for the RECLS model were 0.911, 0.845, and 0.754, respectively, at 1 month, 6 months, and 12 months. Conclusions This study developed prognostic models for lung cancer patients with MPE. The RECLS and RECLSAM scores are practical, clinically applicable models to help guide the selection of optimal treatment strategies.

Abstract
Malignant pleural effusion (MPE) and paramalignant pleural effusion (PPE) remain debilitating complications in lung cancer patients with poor prognosis and limited treatment options. The role of vascular endothelial cells has not been explored in the pleural environment of lung cancer. By integrating MPE and PPE as malignant-associated pleural fluid (MAPF), the current study aimed to evaluate the effect of MAPF on cell proliferation, migration and angiogenesis of HUVEC. First, increased capillaries were identified in the subpleural layer of lung adenocarcinoma. Compatible with pathological observations, the ubiquitous elevation of HUVEC survival was identified in MAPF culture regardless of the underlying cancer type, the driver gene mutation, prior treatments and evidence of malignant cells in pleural fluid. Moreover, MAPF enhanced HUVEC motility with the formation of lamellipodia and filopodia and focal adhesion complex. Tube formation assay revealed angiogenic behavior with the observation of sheet-like structures. HUVEC cultured with MAPF resulted in a significant increase in MAPK phosphorylation. Accompanied with VEGFR2 upregulation in MAPF culture, there was increased expressions of p-STAT3, HIF-1α and Nf-kB. VEGF/VEGFR2 blockade regressed endothelial migration and angiogenesis but not cell proliferation. Our data indicate the angiogenic activities of MAPF on vascular endothelial cells that revealed increased pleural capillaries in lung cancer. Targeting the VEGF/VEGFR2 pathway might modulate the angiogenic propensity of MAPF in future clinical investigations.

Abstract
INTRODUCTION The efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) for EGFR-mutated non-adenocarcinoma (ADC) non-small cell lung cancer patients is not well established. Herein, we investigated key prognostic factors influencing the efficacy of EGFR-TKIs in these patients. METHODS A total of 12,320 lung cancer patients pathologically diagnosed in 2012 at teaching hospitals in Japan were retrospectively selected. The follow-up survey was closed in 2016. RESULTS EGFR-mutated non-ADC patients were more prone to malignant pleural effusion (MPE) and distant metastasis than ADC patients (P = 0.071 and 0.022, respectively). EGFR-mutated ADC patients were likely to have a longer median overall survival (OS) than non-ADC patients [hazard ratio (HR) 1.3 (95 % CI, 0.97-1.8, P = 0.072)-29.5 months (95 % CI, 27.9-31.1 months) versus 19.5 months (95 % CI, 10.8-28.2 months) (P = 0.068)]. There was no significant difference in median OS between EGFR-positive ADC and non-ADC patients receiving treatment with first-generation EGFR-TKI. Among EGFR-positive non-ADC patients, the median OS was significantly longer for patients receiving EGFR-TKI treatment than for those who did not [HR 4.5 (95 % CI, 2.1-9.8, P < 0.001)-25.5 months (95 % CI, 8.1-42.9 months) versus 7.5 months (95 % CI, 3.4-11.6 months) (P < 0.001)]. While there was no significant difference in the median OS for ADC patients with either 19 del or L858R mutations, the median OS was significantly longer for EGFR-mutated non-ADC patients with 19 del than for those with L858R mutation (HR 3.2 [95 % CI, 1.5-6.9, P = 0.004]; it was not reached for 19 del and was 15.5 months for L858R [95 % CI, 6.6-24.4 months], P = 0.002). DISCUSSION EGFR-mutated non-ADC patients were more prone to MPE and distant metastasis. Both ADC and EGFR del19-positive non-ADC patients can benefit from EGFR-TKI treatment, whereas EGFR L858R-positive non-ADC patients might require different therapeutic options.

Abstract
BACKGROUND AND OBJECTIVE The advent of effective anti-cancer therapy has brought about uncertainty on the benefit of early definitive measures for newly diagnosed MPE from lung cancer. This study aims to investigate the outcomes of MPE in this setting. METHODS Lung cancer patients with MPE at first presentation to a tertiary care hospital were followed up till death or censored from 2011 to 2018. Early MPE control measures included chemical pleurodesis or IPC before or shortly after oncological treatment. Predictors of time to MPE re-intervention were identified with Cox proportional hazard analyses. RESULTS Of the 509 records screened, 233 subjects were eligible. One hundred and twenty-seven subjects received oral targeted therapy as first-line treatment and 34 (26.8%) underwent early definitive MPE control measures. Early MPE control measures in addition to targeted therapy, as compared to targeted therapy alone, significantly reduced the subsequent need of MPE re-intervention (23.5% vs 53.8%, P = 0.002). Similar benefits from MPE control measures were found in groups receiving systemic anti-cancer therapy or best supportive care (0% vs 52%, P = 0.003; 18% vs 56.7%, P = 0.024, respectively). In the group with targetable mutations, both early MPE control measures (HR: 0.25, 95% CI: 0.12-0.53, P < 0.001) and the use of targeted therapy (HR: 0.22, 95% CI: 0.10-0.46, P < 0.001) were independently associated with longer time to MPE re-interventions. CONCLUSION Early MPE control measures in lung cancer has additional benefits on reducing the need and prolonging the time to MPE re-intervention, independent of anti-cancer therapies.

Validation of Calprotectin As a Novel Biomarker For The Diagnosis of Pleural Effusion: a Multicentre Trial. Sci Rep 2020; 10:5679.

Abstract
Discriminating between malignant pleural effusion (MPE) and benign pleural effusion (BPE) remains difficult. Thus, novel and efficient biomarkers are required for the diagnosis of pleural effusion (PE). The aim of this study was to validate calprotectin as a diagnostic biomarker of PE in clinical settings. A total of 425 patients were recruited, and the pleural fluid samples collected had BPE in 223 cases (53.7%) or MPE in 137 patients (33%). The samples were all analysed following the same previously validated clinical laboratory protocols and methodology. Calprotectin levels ranged from 772.48 to 3,163.8 ng/mL (median: 1,939 ng/mL) in MPE, and 3,216-24,000 ng/mL in BPE (median: 9,209 ng/mL; p < 0.01), with an area under the curve of 0.848 [95% CI: 0.810-0.886]. For a cut-off value of ≤ 6,233.2 ng/mL, we found 96% sensitivity and 60% specificity, with a negative and positive predictive value, and negative and positive likelihood ratios of 96%, 57%, 0.06, and 2.4, respectively. Multivariate analysis showed that low calprotectin levels was a better discriminator of PE than any other variable [OR 28.76 (p < 0.0001)]. Our results confirm that calprotectin is a new and useful diagnostic biomarker in patients with PE of uncertain aetiology which has potential applications in clinical practice because it may be a good complement to cytological methods.

Abstract
INTRODUCTION The presence of high fluorescent cells (HF-BF) on the Sysmex XN-1000 hematology analyzers has gained interest regarding the prediction of malignant cells in body fluids, but lacks sensitivity. We aimed to increase this sensitivity by combining HF-BF value, automated results, and clinical information. METHODS We evaluated a new workflow for the management of body fluids in the hematology laboratory, including the HF-BF criterion and clinical information. In two laboratories, 1623 serous fluids were retrospectively analyzed on the XN-1000 BF mode. All samples were morphologically screened for malignant cells. Optimal HF-BF cutoffs were determined to predict their presence. Thereafter, the added value of clinical information was evaluated. Other reflex testing rules (eosinophilic count >5% and presence of the WBC Abnormal Scattergram flag) were also used to refine our workflow. RESULTS Optimal HF-BF cutoffs in the two hematology centers were 108 and 45 cells/µL, yielding a sensitivity/specificity of 66.7/93.6% and 86.8/66.6% for malignant cell detection. When adding clinical information, sensitivity/specificity evolved to 100.0/68.9% and 100.0%/not determined. Of 104 samples containing malignant cells, 97 had positive clinical information; the remainder had a HF-BF > cutoff. CONCLUSION Combining clinical information and HF-BF reached 100% sensitivity for malignant cell detection in body fluid analysis. Lack of robustness of the optimal HF-BF cutoff deserves the use of local cutoffs. Rapid automated results reporting from the XN-1000 BF mode are also feasible in clinical practice. Prospective evaluation of the workflow is needed before its implementation in clinical practice.

Abstract
Lung cancer is the most common type of cancer and the leading cause of cancer-associated death worldwide. Malignant pleural effusion (MPE), which is observed in ~50% of advanced non-small cell lung cancer (NSCLC) cases, and most frequently in lung adenocarcinoma, is a common complication of stage III-IV NSCLC, and it can be used to predict a poor prognosis. In the present study, multiple oncogene mutations were detected, including 17 genes closely associated with initiation of advanced lung cancer, in 108 MPE samples using next generation sequencing (NGS). The NGS data of the present study had broader coverage, deeper sequencing depth and higher capture efficiency compared with NGS findings of previous studies on MPE. In the present study, using NGS, it was demonstrated that 93 patients (86%) harbored EGFR mutations and 62 patients possessed mutations in EGFR exons 18-21, which are targets of available treatment agents. EGFR L858R and exon 19 indel mutations were the most frequently observed alterations, with frequencies of 31 and 25%, respectively. In 1 patient, an EGFR amplification was identified and 6 patients possessed a T790M mutation. ALK + EML4 gene fusions were identified in 6 patients, a ROS1 + CD74 gene fusion was detected in 1 patient and 10 patients possessed a BIM (also known as BCL2L11) 2,903-bp intron deletion. In 4 patients, significant KRAS mutations (G12D, G12S, G13C and A146T) were observed, which are associated with resistance to afatinib, icotinib, erlotinib and gefitinib. There were 83 patients with ERBB2 mutations, but only two of these mutations were targets of available treatments. The results of the present study indicate that MPE is a reliable specimen for NGS based detection of somatic mutations.

Abstract
Radiotherapy (RT) is routinely used in cancer treatment, but expansion of its clinical indications remains challenging. The mechanism underlying the radiation-induced bystander effect (RIBE) is not understood and not therapeutically exploited. We suggest that the RIBE is predominantly mediated by irradiated tumor cell-released microparticles (RT-MPs), which induce broad antitumor effects and cause immunogenic death mainly through ferroptosis. Using a mouse model of malignant pleural effusion (MPE), we demonstrated that RT-MPs polarized microenvironmental M2 tumor-associated macrophages (M2-TAMs) to M1-TAMs and modulated antitumor interactions between TAMs and tumor cells. Following internalization of RT-MPs, TAMs displayed increased programmed cell death ligand 1 (PD-L1) expression, enhancing follow-up combined anti-PD-1 therapy that confers an ablative effect against MPE and cisplatin-resistant MPE mouse models. Immunological memory effects were induced.

Abstract
We investigated the prognosis of patients with dry pleural dissemination (DPD) of non-small cell lung cancer (NSCLC) and the risk factors of developing to malignant pleural effusion (MPE).We retrospectively reviewed 104 patients with NSCLC and DPD, confirmed surgically from 1996 to 2016. Incidence rate and risk factors of MPE were analyzed statistically. The prognosis of NSCLC patients with MPE was evaluated using the Kaplan-Meier method.The most common histologic type was adenocarcinoma in 95 (91.3%) patients. The median follow-up duration was 65.5 months and the median survival time was 37.7 months. MPE developed in 51 (49%) patients, and the median effusion-free interval was 41.9 months. The median survival time of the patients with and without MPE was not different (41.3 vs 31.7 months, P = .16). No predictive factors for the development of MPE were identified. Fifteen (14.4%) patients underwent invasive procedures for the management of MPE.Almost half of all patients with NSCLC and DPD experienced MPE, and 14.4% patients developed symptomatic MPE requiring invasive procedures. MPE in DPD did not affect the survival in NSCLC patients.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC) patients benefit from EGFR-tyrosine kinase inhibitors (TKIs) therapy. There are few studies comparing the efficacy between intrapleural chemotherapy combination with TKIs and TKIs alone in controlling re-accumulation of malignant pleural effusions (MPEs). The purpose of the study was to determine if patients with EGFR-mutated NSCLC and MPEs would benefit from intrapleural chemotherapeutics with an oral EGFR-TKI than EGFR-TKI alone. METHODS We evaluated EGFR-mutated lung cancer patients with MPEs in Zhejiang Cancer Hospital. We evaluated the efficacy. Progression-free survival (PFS) and overall survival (OS) was evaluated by Kaplan-Meier method. RESULTS One hundred one NSCLC patients with MPEs at the time of diagnosis were included. We divided the patients into two groups. The overall response rate (ORR) with respect to MPE recurrence between the TKI alone and combination therapy groups was 65.5% (38/58) and 58.1% (25/43) (P=0.449). The disease control rate was 89.7% (52/58) and 86.0% (37/43) (P=0.579), respectively. The PFS in the TKI alone and TKI plus intrapleural drugs was 10.3 and 9.9 months, respectively (P=0.746). The intrapleural PFS was 11.4 and 11.0 months for the TKI alone and combination groups, respectively (P=0.188). The OS was 24.9 and 22.6 months (P=0.543), respectively. Hematologic toxicity and chest pain were more frequent in the combination therapy than TKI alone groups. CONCLUSIONS Intrapleural chemotherapy with TKI did not improve the efficacy of controlling MPEs in patients with EGFR-mutated NSCLC, but may increase adverse events, which are typical side effects of chemotherapy. We could treat these patients with TKI drugs alone combined with pleural effusion drainage.

Abstract
Malignant pleural effusions (MPE) are a common pathology, treated by respiratory physicians and thoracic surgeons alike. In recent years, several well-designed randomized clinical trials have been published that have changed the landscape of MPE management. The European Respiratory Society (ERS) and the European Association for Cardio-Thoracic Surgery (EACTS) established a multidisciplinary collaboration of clinicians with expertise in the management of MPE with the aim of producing a comprehensive review of the scientific literature. Six areas of interest were identified, including the optimum management of symptomatic MPE, management of trapped lung in MPE, management of loculated MPE, prognostic factors in MPE, whether there is a role for oncological therapies prior to intervention for MPE and whether a histological diagnosis is always required in MPE. The literature revealed that talc pleurodesis and indwelling pleural catheters effectively manage the symptoms of MPE. There was limited evidence regarding the management of trapped lung or loculated MPE. The LENT score was identified as a validated tool for predicting survival in MPE, with Brims' prognostic score demonstrating utility in mesothelioma prognostication. There was no evidence to support the use of oncological therapies as an alternative to MPE drainage, and the literature supported the use of tissue biopsy as the gold standard for diagnosis and treatment planning.Management options for malignant pleural effusions have advanced over the past decade, with high-quality randomized trial evidence informing practice in many areas. However, uncertainties remain and further research is required http://ow.ly/rNt730jOxOS.

Abstract
Background: The cytological examination of serous body effusions to diagnose and stage malignancy is well accepted in clinical medicine. Conventional smear (CS) and cell block (CB) study has to be complemented with immunohistochemistry (IHC) for a definitive diagnosis of malignancy and also to differentiate it from reactive mesothelial cells. Cytology microarray (CMA) is a modification of tissue microarray which involves core needle biopsy of multiple cell blocks and embedding it in a single block. Aim: The aim of this study was to assess the effectiveness of IHC technique in CMA for rapid diagnosis of malignancy and to reduce the cost of testing. Materials and Methods: In this study, 82 pleural fluids were collected and subjected to CS and CB study followed by IHC in CMA blocks. Six commonly used antibodies were applied to confirm malignancy and diagnose the primary. Results: Nineteen cases were diagnosed as malignancy by CB method. MOC-31 confirmed adenocarcinoma deposit in 67% cases of which 44% were proved to be of lung primary by TTF1. Conclusions: IHC on CMA blocks of effusion fluids is a very effective technique that can significantly reduce the cost of testing by >70%.

Abstract
Background In epidermal growth factor receptor (EGFR)‐mutant non‐small cell lung cancer (NSCLC), brain metastasis is known as a poor prognosis factor. However, prognostic factors in the patients without brain metastasis remain unclear. In this study, we aimed to clarify the differences between metastatic site and prognosis in common EGFR‐mutant NSCLC patients without brain metastasis. Methods Chemotherapy‐naïve, advanced EGFR‐mutant NSCLC patients without brain metastasis diagnosed between January 2010 and March 2016 were enrolled. We evaluated prognosis according to the presence or absence of bone metastases, liver metastasis, and pleural effusion. Results A total of 50 EGFR‐mutant NSCLC patients without brain metastasis were enrolled. The median progression‐free survival and overall survival were significantly shorter in patients with pleural effusion than in those patients without (progression‐free survival 7.0 months, 95% confidence interval [CI] 3.7–13.0 vs. 13.0 months, 95% CI 9.1–21.7, hazard ratio [HR] 2.29, 95% CI 1.11–4.73, P = 0.020; overall survival 19.5 months, 95% CI 5.7–28.8 vs. 55.3 months, 95% CI 24.0–not evaluable, HR 3.00, 95% CI 1.35–6.68, P = 0.005). Pleural effusion was an independent factor of poor prognosis for progression‐free survival (HR 3.44, 95% CI 1.50–7.88, P = 0.003) and overall survival (HR 2.34, 95% CI 1.00–5.44, P = 0.049). Conclusion Pleural effusion might be a poor prognosis factor for advanced EGFR‐mutant NSCLC patients without brain metastasis treated with first‐generation EGFR‐tyrosine kinase inhibitors. Further precision medicine according to the metastatic site is required.

Abstract
Young lung cancer patients have several distinct characteristics. However, there are limited epidemiological data of genetic abnormalities in this population. We conducted a prospective cohort study to delineate the various oncogenic driver mutations of lung adenocarcinoma in young Asian patients. We consecutively collected malignant pleural effusions (MPEs) from lung adenocarcinoma patients. RNA was extracted from MPEs for mutation analysis by reverse transcription-polymerase chain reaction and direct sequencing. Selected gene mutations for testing included EGFR, HER2, BRAF, KRAS, PIK3CA, JAK2, MEK1, NRAS, and AKT2 mutations, as well as EML4-ALK, ROS1, and RET fusions. We collected MPEs from 142 patients aged ≤50 years and 730 patients aged >50 years. Patients aged ≤50 years (91%) had a higher incidence of driver gene mutations than those aged >50 years (84%; P = .036), especially EML4-ALK (P < .001) and ROS1 (P < .001). Among patients aged ≤50 years, EGFR mutation was the major oncogenic driver mutation. The mutation rates of other genes were 18% EML4-ALK, 6% ROS1, 5% HER2, 1% RET, 1% BRAF, and 1% KRAS. We did not detect PIK3CA, JAK2, MEK1, NRAS, or AKT2 mutations. No difference in gender or smoking history was noted among those with different driver mutations. Patients who had a good performance status or received appropriate targeted therapy had longer overall survival. In conclusion, lung adenocarcinoma in Asian patients aged ≤50 years had a higher gene mutation rate than in those aged >50 years, especially EML4-ALK and ROS1 fusion. Mutation analysis may be helpful in determining targeted therapy for the majority of these patients.

Abstract
BACKGROUND Malignant pleural effusion is a common complication of non-small cell lung cancer (NSCLC); however, treatment options remain limited. This study evaluated the safety and efficacy of sequential intrapleural therapy with lobaplatin and erythromycin for NSCLC-mediated malignant pleural effusion. METHODS Fifty-six patients with NSCLC complicated with malignant pleural effusion were recruited for a prospective single-arm study from December 2014 to 2016; one patient dropped out. In addition to conventional systemic chemotherapy, lobaplatin and erythromycin were intrapleurally injected into subjects. Short and long-term responses were analyzed. The concentration of ultrafilterable platinum in the pleural effusion and plasma were detected at different time points. Incidences of severe adverse reactions were observed. RESULTS In the 55 evaluable patients, the effective rate of pleural effusion was 81.8% after six weeks of treatment. Six and twelve months after treatment, the effective rates were 60% and 21.8%, respectively, and the one-year survival rate was 83.6%. The concentrations of lobaplatin in pleural effusion and plasma two hours after injecting 50 mg lobaplatin into the thoracic cavity were 13.763 ± 1.523 μg/mL and 1.120 ± 0.164 μg/mL, and 17 hours later were 1.961 ± 0.351 μg/mL and 0.578 ± 0.095 μg/mL, respectively. The rate of severe adverse reactions of the first cycle of systemic chemotherapy combined with lobaplatin and erythromycin did not significantly differ from the rate in the second cycle. CONCLUSION Intrapleural combination therapy with lobaplatin and erythromycin is a safe and efficient treatment for patients with NSCLC-mediated malignant pleural effusion.

Abstract
Patients with central airway obstruction (CAO) from advanced lung cancer present with significant morbidity and are assumed to have lower survival. Hence, they are offered only palliative support. We asked if patients who have advanced lung cancer with CAO (recanalised and treated) will behave similarly to those with advanced lung cancer without CAO. This study was a retrospective review of the medical records of the patients managed for advanced lung cancer during 2010 and 2015 at our institution. 85 patients were studied. Median survival and 1-, 2- and 5-year survival were 5.8 months, 30.3%, 11.7% and 2.3% versus 9.3 months, 35.7%, 9.6% and 4.7%, respectively, in the CAO and no CAO groups (p=0.30). More patients presented with respiratory failure (15 (35%) versus none; p=0.0001) and required assisted mechanical ventilation (10 (23.3%) versus none; p=0.001) in the CAO group compared with the no CAO group. Fewer patients received chemotherapy in the CAO group (11 (25.5%)) compared with the no CAO group (23 (54.7%); p=0.008). There was no difference in survival among patients with advanced lung cancer whether they presented with CAO or without CAO. Survival was similar to those without CAO in patients with recanalised CAO despite greater morbidity and lesser use of chemotherapy, strongly advocating bronchoscopic recanalisation of CAO. These findings dispel the nihilism associated with such cases.

Abstract
Malignant pleural effusion (MPE) is a frequent metastatic manifestation of human cancers. While we previously identified KRAS mutations as molecular culprits of MPE formation, the underlying mechanism remained unknown. Here, we determine that non-canonical IKKα-RelB pathway activation of KRAS-mutant tumor cells mediates MPE development and this is fueled by host-provided interleukin IL-1β. Indeed, IKKα is required for the MPE-competence of KRAS-mutant tumor cells by activating non-canonical NF-κB signaling. IL-1β fuels addiction of mutant KRAS to IKKα resulting in increased CXCL1 secretion that fosters MPE-associated inflammation. Importantly, IL-1β-mediated NF-κB induction in KRAS-mutant tumor cells, as well as their resulting MPE-competence, can only be blocked by co-inhibition of both KRAS and IKKα, a strategy that overcomes drug resistance to individual treatments. Hence we show that mutant KRAS facilitates IKKα-mediated responsiveness of tumor cells to host IL-1β, thereby establishing a host-to-tumor signaling circuit that culminates in inflammatory MPE development and drug resistance.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutation non-small cell lung cancer (NSCLC) is an important subtype of lung cancer. The incidence of malignant pericardial effusion (MPCE) in EGFR-mutant NSCLC patients is high. However, there are few researches on the treatmentof this type of patients. METHODS We collected data on clinical characteristics and treatment of advanced NSCLC patients who harboring EGFR mutants and MPCE between January 2010 and December 2016. The treatments were divided into three groups: oral gefitinib combined with pericardial perfusion of hydroxycamptotheci (HCPT) group (gefitinib/HCPT); intravenous chemotherapy combined with pericardial perfusion of HCPT group (chemotherapy/HCPT) and gefitinib monotherapy group. And we retrospectively analyzed patients' outcomes in three groups. RESULTS In 273 advanced NSCLC patients with EGFR mutations, 29 cases had pericardial effusion, among which 6 patients with small amount of pericardial effusion were excluded, and 23 patients were analyzed. Median pericardium progression free survival (PFS) was 247 days. PFS for gefitinib/HCPT group (460 days) was superior to PFS for chemotherapy/HCPT group (94 days, P=0.008) and gefitinib monotherapy group (131 days, P=0.032). As for the efficacy of primary pulmonary lesions, the efficacy in gefitinib/ HCPT group was superior to chemotherapy/HCPT group [objective response rate (ORR): 33.3% vs 12.5%; disease control rate (DCR): 86.7% vs 62.5%]. There is no difference of ORR and DCR between gefitinib/HCPT group and gefitinib monotherapy group. No obvious adverse reaction was observed in all three groups. CONCLUSIONS First-line gefitinib therapy combined with pericardial perfusion of HCPT can improve pericardium PFS for advanced NSCLC patients who harboring EGFR mutants andmalignantpericardial effusion. This finding should be confirmed further through multicenter, prospective clinical trials with large sample size.

Abstract
Background Malignant pleural effusion (MPE) has varied survival and indicates advanced disease. LENT prognostic score is the first validated score used for MPE. This study assessed the role of LENT among palliative care cancer patients and assessed different patient, tumor, and treatment related factors that may affect survival. Methods A retrospective study of advanced cancer patients with MPE, seen in palliative care outpatient clinic (2013-2015) until death, was done. LENT prognostic score could be calculated in 15 patients. Patient, tumor, and treatment related factors that affect survival were assessed. Results The study included 48 patients (70.8% female; 29.2% male) with a median age of 53 years. Lung (41.7%) was the most common primary, and adenocarcinoma (44.7%) was the most common histology. The median overall survival (OS) was 14.5 months (interquartile range [IQR]: 5.25-32.75) and median survival time (ST) was 3 months (IQR: 1-7.75). ST was significantly low with poor Eastern Cooperative Oncology Group (ECOG) performance status (P = 0.002), bilateral effusion (P < 0.001), and with no oncological treatment after MPE diagnosis (P < 0.001). OS and ST were significantly low with lung primary (P = 0.006 and 0.02, respectively). Age, gender, breathlessness, tumor histology, lung metastasis, and interventions for MPE did not significantly affect survival. The median ST in the moderate and high risk LENT groups was 6 and 3 months, respectively (P = 0.16). Conclusion ECOG performance status, bilateral effusion, and no oncological treatment after diagnosis of MPE were associated with poor ST. Lung primary was associated with shorter OS and ST. Small numbers precluded any definitive conclusion on the prognostic value of LENT in our group of patients, and hence larger studies are recommended.

Abstract
Background Occasionally, malignant pleural disease is only detected unexpectedly during surgery in patients with pulmonary adenocarcinoma. Previous studies mostly focused on the role of main tumor resection on patient's outcome, barely addressing the position of postoperative systemic therapy. Methods The medical records of 5321 non-small cell lung cancer patients who underwent thoracic surgery between January 1990 and December 2012 were reviewed. Pulmonary adenocarcinoma patients with unexpected pleural spread noted during surgery were included. The clinical and postoperative treatment variables were assessed for correlation with overall survival. Results In 134 patients identified, main tumor resection was performed in 87 (64.9%) patients, while 89 (66.4%) and 57 (42.5%) patients received postoperative chemotherapy and epidermal growth factor receptor- tyrosine kinase inhibitor (EGFR -TKI) therapy, respectively. Overall, the 5-year survival rate was 30.2% and median survival time was 29.3 months. Multivariate analysis showed main tumor resection and EGFR-TKI therapy were associated with better survival. Mutational status of EGFR was available in 57 patients and 43 (75.4%) had activating mutations. Resection of the main tumor conferred a better outcome in patients without EGFR mutation or with unknown EGFR mutation status and had not been treated with EGFR-TKI therapy (P = 0.003), but not in those with activating EGFR mutation and had been treated with EGFR-TKI (P = 0.857). Conclusions In pulmonary adenocarcinoma patients with unexpected pleural spread detected during surgery, main tumor resection and EGFR-TKI therapy correlated with better survival. Identifying EGFR mutation status before surgery can provide useful information for clinical decision during surgery.

Abstract
Introduction Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are associated with favorable response in EGFR mutant lung cancer. Acquired resistance to reversible EGFR TKIs remains a significant barrier, and acquired EGFR T790M-mutation is the major mechanism. Second-generation irreversible EGFR TKI, afatinib, had also been approved for treating EGFR mutant lung cancer patients, but the mechanism of acquired resistance to afatinib has not been well studied. Results Forty-two patients had tissue specimens taken after acquiring resistance to afatinib. The sensitizing EGFR mutation were all consistent between pre- and post-afatinib tissues. Twenty patients (47.6%) had acquired T790M mutation. T790M rate was not different between first-generation EGFR TKI-naïve patients (50%) and first-generation EGFR TKI-treated patients (46.4%) (p = 0.827). No clinical characteristics or EGFR mutation types were associated with the development of acquired T790M. No other second-site EGFR mutations were detected. There were no small cell or squamous cell lung cancer transformation. Other genetic mutations were not identified in PIK3CA, BRAF, HER2, KRAS, NRAS, MEK1, AKT2, LKB1 and JAK2. Methods Afatinib-prescription record of our department of pharmacy from January 2007 and December 2014 was retrieved. We investigated patients with tissue specimens available after acquiring resistance to afatinib. Enrolled patients should have partial response or durable stable disease of treatment response to afatinib. Various mechanisms of acquired resistance to first-generation EGFR TKIs were evaluated. Histology and cytology were reviewed. EGFR, PIK3CA, BRAF, HER2, KRAS, NRAS, MEK1, AKT2, LKB1 and JAK2 genetic alterations were evaluated by sequencing. Statistical analysis was performed using Chi-square test and Kaplan-Meier method. Conclusions T790M was detected in half of the lung adenocarcinoma after acquiring resistance to afatinib. T790M is still the major acquired resistance mechanism. First-generation EGFR TKI exposure did not influence the prevalence of T790M in lung cancer acquired resistance to afatinib.

Abstract
BACKGROUND Mutation of epidermal growth factor receptor (EGFR) is a prediction marker of the response to tyrosine kinase inhibitor (TKI) drugs in non-small cell lung cancer (NSCLC) patients. As late stage lung cancer patients rarely undergo surgery, samples for EGFR mutation identification usually come from computed tomography (CT)-guided or endoscopic biopsies, which is invasive and costly. Pleural effusion may serve as a less invasive sample for EGFR mutation detection. METHODS We designed a fluorophore-labeled peptide nucleic acid (PNA) probe assay for three types of EGFR mutations, including exon 19 deletions, L858R point mutations and T790M point mutations. The assay was applied in 39 pleural effusion samples from NSCLC patients. The correlation between detected EGFR status and clinical outcome were analyzed. RESULTS In 15 paired samples, PNA probe assay in pleural effusion samples could detect all the mutations that were identified by conventional PCR plus Sanger sequencing in tissue biopsies. In addition, PNA probe assay detected three more T790M mutations. In all 39 pleural effusions, the PNA probe assay detected 27 having at least one of the three EGFR mutations. Among the patients before TKI treatment, those with a sensitizing mutation (either exon 19 deletion or L858R) but without T790M, had 94.1% response rate and longer progression-free survival (mean 10.8 months) than patients without detected mutation (mean 4.2 months) and patients with T790M (mean 1.7 months). CONCLUSIONS Mutations detected in pleural effusions using PNA probe assay are highly associated with clinical outcome. This method appears to be a reliable way for the prediction of the efficacy of EGFR-targeted therapy.

Abstract
PURPOSE In the present study, we examined the relationship between intraoperative pleural lavage cytology findings and presence of epidermal growth factor receptor (EGFR) gene mutations. METHODS We investigated 160 patients who underwent surgical treatment for primary lung adenocarcinoma at our hospital from January 2011 to December 2013 to determine the presence of EGFR gene mutations and pleural lavage cytology. RESULTS In all, 52 subjects (31.5%) were positive EGFR gene mutations, of whom 38 were found to possess the Exon 21 L858R mutation. Intraoperative pleural lavage cytology examinations were performed in 160 subjects and 12 had positive results, of whom 6 were positive for EGFR gene mutations, which was the Exon 21 L858R mutation in all. In a comparison between subjects possessing the Exon 21 L858R mutation and those negative for EGFR gene mutations, lavage cytology-positive (p = 0.02) and vascular infiltration-negative (p = 0.01) were characteristics of the Exon 21 L868R mutation-positive group. CONCLUSION Subjects positive for the EGFR Exon 21 L858R mutation had a higher positive rate of intraoperative pleural lavage cytology than those not possessing EGFR mutations.

Abstract
PURPOSE OF REVIEW Patients with malignant pleural effusions (MPEs) are heterogenous in their disease course, symptom severity, responses to cancer therapies, fluid recurrence rates, and thus need for definitive fluid control measures. To tailor the most appropriate treatment for individual patients, clinicians need to 'phenotype' the patients and predict their clinical course. This review highlights the recent efforts to develop better predictive tools and knowledge gaps for further research. RECENT FINDINGS The LENT scoring system, which includes pleural fluid lactate dehydrogenase, performance status, serum neutrophil-to-lymphocyte ratio and tumor type, allows prediction of the survival of patients with MPE. Symptomatic response after therapeutic pleural drainage is highly variable; ongoing studies aim to identify those who would derive symptomatic benefit from fluid drainages. Multivariate analysis found that patients with low pleural fluid pH [odds ratio (OR) 37.04], large effusions (OR 3.31), and increasing age (OR 1.02) were more likely to require pleurodesis or indwelling pleural catheter placement for fluid control. Better predictive tools for rate of fluid recurrence and likelihood of successful pleurodesis would help guide clinical decision-making. SUMMARY Phenotyping MPE would guide the formulation of optimal management for individual MPE patients.

Abstract
The aim of the present study was to analyze the impact of metastatic status on the prognosis of epithelial growth factor receptor (EGFR) mutation-positive patients with non-small cell lung cancer (NSCLC) treated with first-generation EGFR-tyrosine kinase inhibitors (TKIs). A total of 178 EGFR mutation-positive patients with stage IIIB-IV and relapsed NSCLC who were treated with gefitinib or erlotinib as the first-line treatment were enrolled in the present study. Metastatic status, progression-free survival (PFS), overall survival (OS) and treatment-response rates were investigated. The association between the number of metastatic organ sites and patient prognosis was also investigated. The median age at the time of treatment was 72 (range, 39-91) years. A total of 168 patients had adenocarcinoma; 156 were treated with gefitinib. Patients with brain metastases, bone metastases, liver metastases and pleural effusion exhibited a significantly reduced PFS and OS time in the univariate analysis, compared with patients without each of these symptoms. In the multivariate analysis, bone metastasis was associated with a poorer PFS (hazard ratio, 2.11; 95% confidence interval, 1.44-3.09; P<0.001) and brain metastasis was associated with a poorer OS (hazard ratio, 2.41; 95% confidence interval, 1.46-3.95; P<0.001). No association was observed between metastatic status and treatment response rates. Higher numbers of different sites of organ metastases were associated with significantly poorer PFS and OS. Bone, brain metastasis and higher numbers of metastatic organ sites are negative prognostic factors for EGFR mutation-positive NSCLC patients treated with first-generation EGFR-TKIs.

Abstract
Abstract: Background and Objective: Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitors (EGFR-TKIs) are effective against lung adenocarcinoma. However, limited data is available assessing the effectiveness of EGFR-TKI use in preventing re-accumulation of MPE. To our knowledge, there is no literature on comparison of talc pleurodesis with EGFR-TKIs alone on re-accumulation of MPE in Asian population. We investigated if EGFR-TKI therapy for advanced lung adenocarcinoma with malignant pleural effusion (MPE) is also successful in preventing pleural fluid re-accumulation following initial drainage. Methods: An observational cohort study of patients with lung adenocarcinoma and MPE in the year 2012 was conducted. Results: 70 patients presented with MPE from lung adenocarcinoma. Fifty six underwent EGFR mutation testing of which 39 (69.6%) had activating EGFR mutation and 34 (87.1%) received TKI. 20 were managed by pleural fluid drainage only whereas 14 underwent talc pleurodesis following pleural fluid drainage. Time taken for the pleural effusion to re-accumulate in those with and without pleurodesis was 9.9 vs. 11.7 months, p=0.59 respectively. More patients (n=10, 25.6%) with activating EGFR mutation presented with complete opacification (white-out) of the hemithorax compared to none without activating EGFR mutation (p=0.02). Conclusion: In TKI eligible patients, early talc pleurodesis may not confer additional benefit in preventing re-accumulation of pleural effusion and may be reserved for non-adenocarcinoma histology, or EGFR negative adenocarcinoma. Complete opacification of the hemithorax on presentation may serve as an early radiographic signal of positive EGFR mutation status.

Abstract
Comprehensively investigate the association of CT morphology and clinical findings of adenocarcinoma with EGFR mutation status. Retrospectively included 282 patients who was pathologically proved as lung adenocarcinoma with known EGFR mutation status (mutations: 138 patients, female: 86, median age: 66 years; wildtype: 144 patients, female: 67, median age: 62 years) and their pre-treatment CT scans were analyzed. CT findings and clinical information were collected. Univariate and multivariable logistic regression analysis were performed. Adjusted for age, gender and smoking history of two groups, significantly more patients with pleural tags, pleural and liver metastases were found in the EGFR mutated group (P = 0.007, 0.004, and 0.043, respectively). Multivariable logistic regression analysis found that the model included age, gender, smoking history, air bronchogram, pleural tags, pleural and liver metastasis had a moderate predictive value for EGFR mutation status (AUC = 0.741, P < .0001). Exon-19 deletion was associated with air bronchogram which adjusted for age, gender and smoking history (P = 0.007, OR: 2.91, 95%CI: 1.25–7.79). The evidence of pleural tags, pleural and liver metastases go along with a higher probability of EGFR mutation in adenocarcinoma patients and air bronchogram is positively associated with Exon-19 deletion mutation.
