Abstract
Two-dimensional Mo2C/Mo2N composites were synthesized by high temperature ball milling and used as support materials for fabricating a chlorpyrifos (CPF) aptasensor. Gold nanoparticles (Au NPs) were electrodeposited on the surface of a Mo2C/Mo2N-modified electrode to connect with the ferrocene (Fc) probe via Au-S bonds. The Fc probe can hybridize with the aptamer probe to form a double-stranded structure. The addition of CPF made the double strands melt and the Fc probe approached the surface of the electrode, thereby resulting in amplification of the electrochemical response. The current response of the aptasensor for detecting CPF in solutions linearly varied from 0 to 400 ng mL-1 (with a maximum at 0.98 V vs. Ag/AgCl). The Au NPs/Mo2C/Mo2N composites exhibited satisfactory electrochemical behavior due to their excellent electrical conductivity and large surface area. This ultrasensitive aptasensor showed a low limit of detection of 0.036 ng mL-1. It was applied to determine CPF in real samples with acceptable recoveries from 94.7 to 116.7%, and the relative standard deviation was from 2.57 to 7.08%.Graphical abstract Schematic diagram of the manufacturing process of the aptasensor. Electrochemical aptasensor based on Mo2C/Mo2N/Au NP composites show excellent performance in detecting CPF.

Abstract
AIMS To investigate the efficacy and safety of minimally invasive bronchoscopic interventions for patients with tracheobronchial mucoepidermoid carcinoma (MEC). METHODS Patients with tracheobronchial MEC were included in this retrospective study, and the clinical features, histologic grading, treatments, and cumulative survival rates were calculated. Patients were categorized into child (n = 16) and adult (n = 19) group according to their ages. Histologic grading, treatments, and survival status were compared between the two groups. RESULTS In pathology, high-grade MEC counts for 6.77% and 42.10% in the child and adult group, respectively. As tumor growth pattern was concerned, 93.33% and 21.05% tumors in the child and adult group present intratracheal type. Multiple bronchoscopic interventions were conducted, including rigid bronchoscopy, argon plasma coagulation (APC), dioxide carbon cryotherapy, and electric loop. Tumors could be removed by multiple bronchoscopic interventions. Bronchoscopy-associated complications were rare, including an oral mucosa injury and a glottis edema. In the child group, one patient underwent left upper lung lobectomy. In the adult group, lobectomy and/or chemotherapy and/or radiotherapy were conducted in seven patients. The 5-year survival rate was 100% and 68.90% in the child and the adult group, respectively. CONCLUSIONS Almost all children have low-grade and intratracheal MEC; 2/5 adults have invasive high-grade MEC. Multiple bronchoscopic interventions are effective in erasing low-grade intratracheal MEC without severe complications. For high-grade invasive MEC, aggressive and comprehensive therapy should be considered.

Abstract
Background Primary pulmonary mucoepidermoid carcinoma (PMEC) is a rare malignant tumor, and the clinical manifestations lack specificity. The study evaluates the prognostic factors and constructs a practicable nomogram to estimate the individualized survival status for PMEC patients. Methods Surveillance, Epidemiology, and End Results (SEER) database was used to selected eligible patients between 1975 and 2016. The baseline characteristics including age, sex, race, marital status, tumor stage, differentiated degree, tumor laterality, primary tumor site, tumor size, lymph node metastases status, distant metastases status, surgery, chemotherapy, and radiation. We identified independent variables to build 3-, 5-, 10-year overall survival (OS) and cancer-specific survival (CSS) nomograms by univariate and multivariate analyses. Results A total of 438 PMEC patients met our selection criteria. In multivariate analysis, age, tumor stage, differentiated grade, tumor size, lymph node metastases status, distant metastases status, surgery and radiation were involved in the nomogram. The C-index (0.887 (95% CI: 0.863-0.911), calibrate plots and ROC curves (AUC =0.941, 0.951, 0.935 for 3-, 5-, 10-year OS, respectively) indicated the satisfied accuracy and practicability of our nomograms. Compared to TNM system, our model also showed a superior prediction (IDI =0.167, 0.171, 0.172, P<0.001). Conclusions We built OS (CSS) nomograms that can accurately estimate individualized survival time and identify the risk classification of PMEC.

Abstract
Preoperative fine needle aspiration diagnosis and cyto-histologic correlation of primary pulmonary mucoepidermoid carcinoma have rarely been described in detail in the literature. A 26-year old male presented at our institution with cough, bloody sputum, and a 4.3 cm left lower lobe lung mass. He was accurately diagnosed with pulmonary mucoepidermoid carcinoma on preoperative aspiration cytology. The patient subsequently proceeded to left lower lobectomy, confirming the diagnosis. In this article, we present a detailed report of primary pulmonary mucoepidermoid carcinoma describing the cytologic and histologic morphologic features, its differential diagnosis with review of the literature.

Abstract
Background To determine the predictive CT imaging features for diagnosis in patients with primary pulmonary mucoepidermoid carcinomas (PMECs). Materials and methods CT imaging features of 37 patients with primary PMECs, 76 with squamous cell carcinomas (SCCs) and 78 with adenocarcinomas were retrospectively reviewed. The difference of CT features among the PMECs, SCCs and adenocarcinomas was analyzed using univariate analysis, followed by multinomial logistic regression and receiver operating characteristic (ROC) curve analysis. Results CT imaging features including tumor size, location, margin, shape, necrosis and degree of enhancement were significant different among the PMECs, SCCs and adenocarcinomas, as determined by univariate analysis (P < 0.05). Only lesion location, shape, margin and degree of enhancement remained independent factors in multinomial logistic regression analysis. ROC curve analysis showed that the area under curve of the obtained multinomial logistic regression model was 0.805 (95%CI: 0.704–0.906). Conclusion The prediction model derived from location, margin, shape and degree of enhancement can be used for preoperative diagnosis of PMECs.

Abstract
Introduction: Mucoepidermoid carcinoma (MEC) is a primary salivary gland tumor also arising from nonsalivary gland organs of the body such as submucosal glands of tracheobronchial tree. Surgical resection with negative margins is the treatment of choice. All efforts should be made to preserve as much lung parenchyma as possible, by various bronchoplastic procedures. We present our experience with mucoepidermoid tumors and review their management options including lung preservation techniques and outcome of surgery. Materials and Methods: This is a retrospective analysis of prospectively maintained data of 14 patients who underwent surgery for MEC. Their demographic data; clinical presentation; and preoperative, intraoperative, and postoperative details were recorded. All patients underwent contrast-enhanced computed tomography of chest and bronchoscopy as part of workup for diagnosis and to assess the location, size, and extent of tumor; extraluminal component; and status of distal lung parenchyma. Results: There were eight male and six female patients. The median age at the time of surgery was 28.36 years (range 22–45 years). The procedures performed included right upper lobectomy and right pneumonectomy in one patient each, left main bronchus sleeve resection in six patients, left upper sleeve lobectomy in three patients, and carinal resection and reconstruction of neo carina in three patients. Twelve (85.7%) of our patients underwent lung-preserving surgery. The median hospital stay and chest tube removal duration was 4 and 3 days, respectively. The median tumor size was 1.91 cm (range 1–8 cm). The median follow-up was 24 months (ranging from 6 to 78 months). Conclusion: Radical surgery to achieve R “0” resection with aggressive emphasis on lung preservation is the mainstay of treatment of MEC. Greater awareness of these tumors is necessary to avoid misdiagnosis and to prevent delaying of potential complete resection of MEC.

Abstract
Objectives: The objective of the study was to review the imaging features of proven pediatric primary lung tumors, with a purpose of detecting key distinguishing features among the various entities. Materials and Methods: We retrospectively reviewed multidetector computed tomography (CT) images of 17 pediatric patients with primary lung tumors. For each examination, various CT image descriptors were used to characterize the pulmonary nodules/masses; including location, size, number, morphology, cavitation, calcification, intense enhancement, airway involvement, chest wall/pleural involvement, mediastinal/vascular involvement, and nodal enlargement. Results: The age of the patients ranged from 2 to 18 years (mean age of 9.5 years). Approximately 35.3% of tumors were benign and 64.7% were aggressive/malignant. Nine distinct histopathologic tumor entities were found. Common tumor types were recurrent respiratory papillomatosis (4) and inflammatory myofibroblastic tumor (4) with two endobronchial tumors including carcinoid and mucoepidermoid carcinomas. Besides invasion and nodal enlargement, large size and central location (P < 0.05) were predictors of aggressiveness/malignancy. Multiple lesions and cavitation (P < 0.05), on the other hand, were frequent in benign lesions. Conclusion: On imaging, location and morphological markers can allow diagnosis in majority of the tumors.

Abstract
Aim To analyze the radiological, clinical, and prognostic features of primary pulmonary salivary gland-type tumors (SGTs) and improve their diagnosis. Materials and Methods We retrospectively collected clinical and pathological data for 32 SGT cases confirmed by pathology and analyzed their radiological features, clinical presentations, and treatment outcomes. Results Mucoepidermoid carcinoma (MEC) was more likely to occur in younger patients than was adenoid cystic carcinoma (ACC) (35 ± 15 years vs 48 ± 16 years, p=0.038). MEC was equally distributed between both sexes, whereas ACC was more frequent in females (66.7%). The main presenting symptom of SGT was cough (56.3%), followed by dyspnea (40.6%), associated with the tumor location. ACC more frequently involved the trachea or main bronchus (86.7% vs 25.0%, p=0.001) and more commonly presented as lobulated or circumferential thickening than MEC (93.3% vs 37.5%, p=0.002). MEC more frequently presented as obvious enhancement than ACC (68.8% vs 31.3%, p=0.001). CT findings suggestive of airway obstructive disease were more likely to be observed with MEC than ACC (73.3% vs 25.0%; p=0.021). The SUVmax in 8 of 10 patients with PET/CT data exceeded 2.2 but was less than 6.0. The overall survival (OS) at 3 and 5 years was 90.9% and 72.2% in all patients, respectively. Tumor-node-metastasis (TNM) stage, surgery, and patient age were associated with OS (p ≤ 0.001, p=0.001, and p=0.001, respectively). Conclusion SGTs commonly occur in patients at a young age and are associated with weak invasive features and a good prognosis. The predominant site and CT characteristics are significantly different between ACC and MEC.

Abstract
Pulmonary mucoepidermoid carcinoma is an extremely rare intrathoracic malignancy, comprising less than 1% of all lung tumours. These are very slow growing and are classified into low grade and high grade based on histological features. Surgical resection is the primary treatment with excellent outcomes, while chemotherapy or radiotherapy effectiveness is not known. Preoperative fluorine-18 fluorodeoxyglucose positron emission tomography/CT (18F-FDG PET/CT) is useful for predicting tumour grade and postsurgical prognosis.A clinical case of a 31-year-old woman who presented with dyspnoea on exertion, cough and wheezing is reported. Imaging studies revealed a mass involving the left lower lobe bronchus and atelectasis. 18F-FDG PET/CT showed uptake in the described mass with a maximum standardised uptake value of 9.7. Complete surgical resection was performed, and pathological examination revealed a high-grade mucoepidermoid carcinoma with tumour-free margins. Adjuvant chemotherapy was given and there is no evidence of tumour recurrence.

Abstract
Background: Tracheobronchial mucoepidermoid carcinoma (MEC) is a rare airway tumor in adults for which surgery is considered a first-line treatment. However, some patients already lost the best opportunity of a surgical intervention when diagnoses are confirmed, and surgery causes considerable trauma resulting in partial loss of pulmonary function. Moreover, the tumor is resistant to radiotherapy and chemotherapy. These factors make the treatment of tracheobronchial MEC challenging. This study aimed to evaluate the safety and efficacy of interventional bronchoscopic therapy in adult patients with tracheobronchial MEC. Methods: We retrospectively analyzed the clinical manifestations, bronchoscopic interventions, complications, and outcomes of 11 adult patients with tracheobronchial MEC. Paired t-test was used to analyze the parameters of the American Thoracic Society Dyspnea Index and the Karnofsky Score before and after the first interventional bronchoscopic therapy. Results: All tumors occurred in the main bronchus and were easily visualized by bronchoscopy. After interventional bronchoscopic therapy, the symptoms of all patients showed significant improvement. The American Thoracic Society Dyspnea Index decreased from 1.91 ± 1.22 to 0.27 ± 0.47 (t = 6.708, P < 0.001) and the Karnofsky Score increased from 78.18 ± 16.62 to 95.46 ± 8.20 (t = −5.190, P < 0.001). Bronchoscopic intervention did not result in serious complications or mortality. During the follow-up period between 3 and 96 months after the first therapy, the following results were noted: (1) among the eight patients with low-grade tracheobronchial MEC, only one patient had a relapse and agreed to surgical treatment; (2) among the three patients with high-grade tracheobronchial MEC, one patient required repeated bronchoscopic interventions, one patient died of pulmonary infection, and one patient died of systemic failure owing to tumor metastasis. Conclusions: Interventional bronchoscopic therapy, as an alternative treatment, shows promise in some adult patients with low-grade tracheobronchial MEC confined to the bronchus. However, for adult patients with high-grade tracheobronchial MEC, early diagnosis and surgical treatment are still strongly recommended.

Abstract
AIM To delineate the multisection computed tomography (MSCT) features and the clinical characteristics of primary pulmonary mucoepidermoid carcinoma (PMEC). Prognostic factors were also analysed. MATERIALS AND METHODS A retrospective study was undertaken to investigate the medical records and MSCT performance of histopathologically confirmed PMECs from 2007 to 2015. RESULTS A total of 83.3% of patients with high-grade PMECs were aged >40 years, whereas there were 1.5-times more women than men with low-grade PMECs. Cough (n=29) and haemoptysis (n=12) were the most common symptoms. Upon MSCT, 30 cases showed a round or lobulate mass, and few demonstrated bronchial-wall thickening or cavities. Distal obstruction (n=14) and "air crescent sign" (n=5) could be detected. Tumours showed mild (n=19), moderate (n=5), and marked enhancement (n=5). Moreover, 18 cases showed foci of low density in lesions. Mean survival for patients with low-grade PMECs was 59.2 months, whereas that for high-grade PMECs was 20.4 months; 3-year survival rates were 55% and 14%, respectively. Tumour staging was a significant independent predictor of survival according to the Cox proportional hazards model. CONCLUSION High-grade PMECs occurred more frequently in patients aged >40 years and were more predominant in men. Young females were predisposed to having low-grade PMECs. MSCT revealed an oval or lobulate mass with mild enhancement, as manifested by calcification and visible mucus lakes, which may be suggestive of PMECs. Furthermore, a central nodule or mass may suggest low-grade PMECs; high-grade PMECs tend to be peripheral and associated with lymph-node metastasis. Pathological grade, lymph node metastasis, and TNM stage correlate with the survival of patients with PMEC.

Abstract
INTRODUCTION Bronchial localization of Mucoepidermoid carcinoma (MEC) is rare. The precise nature of these neoplasms is not yet clear and little is known on the histogenesis and pathogenesis of the disease. Here we present a case of a bronchial MEC with a detailed pathological, immunohistochemical, and molecular analysis. PRESENTATION OF A CASE A 46 years old Caucasian male patient was referred to our Unit for fever, non productive cough and dyspnea lasting for two months. The chest CT scan evidenced an 8-mm intraluminal lesion in the left main bronchus, in correspondence of the origin of the lingular segmental bronchus. Multiple biopsies were performed through bronchoscopy, and the diagnosis of a mucoepidermoid carcinoma of the lung was obtained. A left upper lobectomy was performed. The histopathological examination confirmed the preoperative diagnosis and stage (pT1N0M0). No further therapies were employed, given the stage of the disease. The patient is presently free of disease, approximately three years after surgery. DISCUSSION The treatment of MECs is usually surgical by traditional or sleeve lobectomy, performed with an open or video-assisted technique, with the aim of an R0 resection. In this stage the prognosis is excellent. Conversely, high grade tumors seems to be particularly aggressive, even more than other NSCLC. CONCLUSIONS Low grade type of Bronchial MEC, as our case, is often characterized by an optimal clinical management and prognosis. The lack of EGFR sensitizing mutations does not preclude the use of TKIs, which may be extremely useful in patients non responsive to other therapies.

Abstract
OBJECTIVE The objective of our study was to characterize the CT features and clinical findings of low-grade and high-grade mucoepidermoid carcinoma (MEC) of the lung. MATERIALS AND METHODS The CT findings and clinical information of 17 consecutive patients with primary low-grade (n = 11) or high-grade (n = 6) MEC were analyzed retrospectively. We assessed tumor location, size, contour, margin, density, calcification, obstructive changes, presence of metastasis, and enhancement. RESULTS In patients with low-grade MEC, tumor location was central in 10 and peripheral in one. In contrast, one and five tumors in patients with high-grade MEC were central and peripheral, respectively. There was a significant difference between central and peripheral locations among tumor grades (p = 0.005). In low-grade MECs, tumor contour was smoothly oval (n = 3) or spheric (n = 4); four were lobular. In five patients with low-grade MEC, tumors had well-defined margins; margins in the other six were poorly defined. Tumor density was homogeneous and heterogeneous in eight and three low-grade tumors, respectively. All six high-grade tumors had heterogeneous density, lobular contours, and poorly defined margins. Enhancement in both low-grade and high-grade tumors was greater than that of chest wall muscles, and low-grade tumors showed greater enhancement (46.90 ± 20.44 HU) than did high-grade tumors (22.50 ± 8.38 HU) (p = 0.015). CONCLUSION A markedly enhanced homogeneous central bronchial nodule or mass may suggest low-grade MEC. High-grade MEC tends to be peripheral, to have poorly defined margins, and to be lobular, heterogeneous nodules or masses with less enhancement.

Abstract
Aims and Background Bronchial mucoepidermoid carcinoma is a rare disease in children, and lobectomy is traditionally considered as a first-line treatment. As the tumor is characterized by intraluminal growth, low malignancy and superficial infiltration of bronchial walls, bronchoscopic interventional therapy may provide an alternative treatment with favorable results. The aim of the study was to evaluate the efficacy and safety of bronchoscopic therapies for bronchial mucoepidermoid carcinoma in children. Methods and Study design Clinical manifestations, multiple bronchoscopic interventions and outcomes in 6 children with bronchial mucoepidermoid carcinoma were retrospectively analyzed. Results The median age was 8.7 years (range 4 to 12 years). All the tumors were located in the lobar bronchus and were detected by computerized tomography. Diagnoses of low-grade mucoepidermoid carcinoma were made based on biopsies obtained via bronchoscopy. Five tumors were classified as intraluminal type and successfully eradicated by carbon dioxide cryotherapy and argon plasma coagulation under bronchoscopy. The other tumor in patient 3 was classified as the mixture type and could not be removed by a bronchoscopic, so left upper lobectomy was performed. For each patient, interventional procedures were conducted on the average for 6 times. No recurrence was detected by bronchoscopic inspections or computed tomography scans during follow-ups for 16-72 months. Conclusions Multiple bronchoscopic procedures, as alternative treatments, are effective in removing bronchial mucoepidermoid carcinoma mucoepidermoid carcinoma in children without any major complications.

Abstract
A wide variety of pathologic processes, both benign and malignant, affect the central airways. These processes may be classified into 4 distinct groups: anatomic variants, lesions that result in focal or diffuse airway narrowing, and those that result in multinodular airway disorder. Key to the accurate assessment of the central airways is meticulous imaging technique, especially the routine acquisition of contiguous high-resolution, 1-mm to 1.5-mm images. These images enable high-definition axial, coronal, and sagittal reconstructions, as well as advanced imaging techniques, including minimum intensity projection images and virtual bronchoscopy. Current indications most commonly include patients presenting with signs and symptoms of possible central airway obstruction, with or without hemoptysis. In addition to diagnosing airway abnormalities, computed tomography (CT) also serves a critical complementary role to current bronchoscopic techniques for both diagnosing and treating airway lesions. Advantages of CT include noninvasive visualization of the extraluminal extent of lesions, as well as visualization of airways distal to central airways obstructions. As discussed and illustrated later, thorough knowledge of current bronchoscopic approaches to central airway disease is essential for optimal correlative CT interpretation.

Abstract
A variety of pathologic processes can involve the central airways. Abnormalities may either diffusely or focally involve the tracheal or mainstem bronchial walls. Diseases that diffusely involve the tracheal wall can be subclassified as sparing the membranous trachea or circumferentially involving the tracheal wall. Focal diseases of the trachea and mainstem bronchi include benign and malignant causes. Additionally, congenital and acquired morphologic abnormalities of the trachea will be reviewed.

Abstract
INTRODUCTION Mucoepidermoid tumours (TME) are rare tumours arising from the submucosal glands of the tracheobronchial tree. The majority of these tumours develop in a benign fashion but some of them are malignant. The latter can be easily mistaken for adenosquamous carcinomas. PATIENTS AND METHOD We have reviewed 22 patients suffering from TME observed over a period of 25 years. Two arose from the trachea and 20 from the cartilaginous bronchi; 12 of these tumours had macroscopic and histological criteria of low-grade malignancy, 4 had macroscopic and 6 macroscopic and microscopic criteria of high grade malignancy. RESULTS Prognosis of the latter was very poor and no survival observed after 6 years follow-up, a behavior similar to that observed in non-small cell lung carcinomas and adenosquamous carcinomas. CONCLUSION The best treatment of these orphan tumours remains surgery.

Abstract
Primary bronchial mucoepidermoid carcinoma in the lung is relatively rare. It rarely presents with the highly malignant biological characteristic of bone marrow metastasis. We describe a case of this disease with bone marrow metastasis. A 56-year-old man with the primary manifestation of bone pain and bloodstained sputum had two abnormal shadows on the left inferior lobar bronchus and peripheral tissue of the lower lobe of the left lung, respectively. Computed tomography-guided percutaneous puncture biopsy and bone imaging confirmed the diagnosis of high-grade bronchial mucoepidermoid carcinoma with bone metastasis. However, the patient soon presented with progressive hemoglobin and platelet decline and severe multi-organ hemorrhage. Subsequently, we performed bone marrow aspiration and biopsy, which revealed malignant cells and necrosis. The patient deteriorated rapidly from the disease, and died on the 16th day of admission. We hope that this case report will increase awareness of the possibility of primary high-grade bronchial mucoepidermoid carcinoma metastasizing to the bone marrow, which might be a poor prognostic factor.

Abstract
Mucoepidermoid carcinoma (MEC) of the lung is a rare endobronchial tumor accounting for up to 0.2% of primary lung cancer. We report a patient with MEC who presented with cough, hemoptysis, and localized findings on chest examination. This case emphasizes the importance of obtaining adequate biopsy to establish the correct diagnosis. In addition, it highlights that MEC of the lung usually presents in the low-grade form, carrying a favorable prognosis.
