Mol Carcinog 2024; 63:962-976. [PMID: 38411298 DOI: 10.1002/mc.23701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/23/2024] [Accepted: 02/02/2024] [Indexed: 02/28/2024]
Abstract
It is well known that 5-methylcytosine (m5C) is involved in variety of crucial biological processes in cancers. However, its biological roles in lung adenocarcinoma (LAUD) remain to be determined. The LUAD samples were used to assess the clinical value of NOP2/Sun RNA Methyltransferase 2 (NSUN2). Dot blot was used to determine global m5C levels. ChIP and dual-luciferase assays were performed to investigate the MYC-associated zinc finger protein (MAZ)-binding sites in NSUN2 promoter. RNA-seq was used to explore the downstream molecular mechanisms of NSUN2. Dual luciferase reporter assay, m5C-RIP-qPCR, and mRNA stability assay were conducted to explore the effect of NSUN2-depletion on target genes. Cell viability, transwell, and xenograft mouse model were designed to demonstrate the characteristic of NSUN2 in promoting LUAD progression. The m5C methyltransferase NSUN2 was highly expressed and caused elevated m5C methylation in LUAD samples. Mechanistically, MAZ positively regulated the transcription of NSUN2 and was related to poor survival of LUAD patients. Silencing NSUN2 decreased the global m5C levels, suppressed proliferation, migration and invasion, and inhibited activation of PI3K-AKT signaling in A549 and SPAC-1 cells. Phosphoinositide-3-Kinase Regulatory Subunit 2 (PIK3R2) was upregulated by NSUN2-mediated m5C methylation by enhancing its mRNA stabilization and activated the phosphorylation of the PI3K-AKT signaling. The present study explored the underlying mechanism and biological function of NSUN2-meditated m5C RNA methylation in LUAD. NSUN2 was discovered to facilitate the malignancy progression of LUAD through regulating m5C modifications to stabilize PIK3R2 activating the PI3K-AKT signaling, suggesting that NSUN2 could be a novel biomarker and promising therapeutic target for LUAD patients.

Abstract
Background Non‐small‐cell lung cancer (NSCLC) still occupied the leading reason of cancer death due to lack of availability of early detection. This study aimed to identify the effective biomarkers for the early‐stage NSCLC diagnostics based on plasma snoRNAs. Materials and Methods The differential snoRNAs between lung cancer patients and healthy donors were analyzed using the SNORic and TCGA databases. SNORD42B and SNORD111 were screened out and further verified in 48 FFPE NSCLC and adjacent normal tissues, as well as in plasma from 165 NSCLC patients and 118 health donors using qRT‐PCR. Next, their diagnostic efficiency, as well as combined with carcinoembryonic antigen (CEA), was obtained by the analysis of receiver operating characteristic (ROC). Results We first screened out 47 top differential snoRNAs, among which the top 10 upregulated snoRNAs in LUAD were U44, U75, U78, U77, SNORD72, SNORD13, SNORD12B, SCARNA5, U80, SNORD41, and in LUSC were U44, U75, U78, SNORD41, SNORD111, SNORA56, U17a, SNORD35A, SNORD32A, SNORA71D. SNORD42B and SNORD111 was significantly increased not only in tumor tissues but also in plasma from NSCLC and early‐stage NSCLC patients. They were capable to act as promising biomarkers for NSCLC and early‐stage NSCLC diagnosis. Moreover, CEA diagnostic efficiency for early‐stage NSCLC was significantly improved when combined with these two plasma snoRNAs. Conclusion SNORD42B and SNORD111 could act as the potential and non‐invasive diagnostic biomarkers for NSCLC and early‐stage NSCLC.

Abstract
Tumor-associated macrophages (TAMs) are the major components of the tumor microenvironment that contribute to metastasis in lung adenocarcinoma (LUAD). The potential of TAM-derived exosomes for biomarker discovery in tumor initiation and progression has been recently reported. However, studies on macrophage-derived exosomes in LUAD remain limited. We investigated the role of M2 macrophage-derived exosomes in LUAD both in vivo and in vitro and its underlying mechanism. We showed that the infiltration of M2 macrophages was positively correlated with LUAD metastasis. M2 macrophage-derived exosomes could be taken up by LUAD cells to promote cell migration, invasion, and angiogenesis. Furthermore, miR-942 could be packaged into exosomes secreted by M2 macrophages. Mechanistically, exosomal miR-942 regulates FOXO1 protein expression by binding to the 3'-UTR region of FOXO1 and further alleviates β-catenin inhibition in LUAD cells. Collectively, we demonstrated that M2 macrophage-derived miRNA-containing exosomes promote LUAD cell invasion and migration and facilitate angiogenesis, thereby providing a new therapeutic target for metastatic LUAD.

Abstract
Proximal pulmonary artery (PA) embolization is a dramatic interventional radiology procedure performed to control recurrent, life-threatening hemoptysis. Distal PA embolization procedures are commonly performed, and preoperative proximal PA embolization procedures have been reported, but to the best of our knowledge there has not been a reported case of a proximal PA embolization to treat hemoptysis. Here, we present a case of a complete proximal PA embolization that effectively resolved recurrent hemoptysis in a patient with a lung tumor following a failed bronchial artery embolization.

Abstract
Background Airway stenting is frequently used in the palliative treatment of patients with advanced tumor-induced airway stenosis and fistulas. However, there is paucity of studies regarding the use of airway stents in restoring patency. The aim of the study was to assess the efficacy and safety of hybrid silicon Y stents and covered self-expanding metal stents (SEMS) and in reestablishing patency in airway stenoses and fistulas. Methods This retrospective study included 31 patients between January 2016 to December 2019 with inoperable complex malignant airway stenoses and fistulas, managed with Silicone Y stents, and covered SEMS. The clinical details, clinical outcomes and complications up to 6 months were extracted from medical records. The improvement of performance was assessed based on modified British Medical Research Council (mMRC) dyspnea scores (t=6.892, P<0.001), Karnofsky Performance Scores (KPS) (t=-11.653, P<0.001), and performance status (PS) (t=3.503, P<0.001). Result A total of 31 silicon Y stents and 35 covered SEMSs were inserted. Of the 31 patients (M:F 20:11; age: 54.64±9.57), 25/31 (80.6%) experienced immediate relief of symptoms following stent placement. Patients' mMRC dyspnea scores, KPS, and PS showed significant improvement following stenting. The mean duration of stent placement was 146.3±47.7 days, and 17/31 (55%) patients were alive at 6 months. No major complications related to hybrid stenting were observed during the follow-up period. Conclusions Hybrid stenting is a feasible and safe palliative treatment for malignant airway stenosis and fistulas to improve quality of life and can be performed without major complications.

Abstract
Background The study aimed to explore the efficacy and safety of drug-eluting beads bronchial arterial chemoembolization (DEB-BACE) plus intercostals arterial infusion chemotherapy in non-small cell lung cancer (NSCLC) patients with refractory malignant pleural effusion (MPE). Methods 17 NSCLC patients with refractory MPE treated by DEB-BACE plus the intercostals arterial infusion chemotherapy (DEB-BACE group) were recruited. Their treatment response [complete remission (CR), partial remission (PR), overall efficacy, failure] for MPE was assessed at 1 month after therapy; adverse effects were recorded; MPE progression-free survival and overall survival (OS) were calculated. Moreover, 19 NSCLC patients with refractory MPE treated by conventional chemotherapy were reviewed as control (chemotherapy group), then their medical records were collected. Results With respect to MPE response, DEB-BACE group exhibited increased CR (82.4% vs. 10.5%, P<0.001) and overall efficacy (100.0% vs. 52.6%, P=0.001), similar PR (17.6% vs. 42.1%, P=0.112) while less failure (0.0% vs. 47.4%, P=0.001) compared to chemotherapy group. Furthermore, OS was prolonged in DEB-BACE group (median: 13.4; 95% CI: 11.0–15.8 months) than chemotherapy group (median: 7.0; 95% CI: 4.4–9.6 months) (P=0.002). Further analyses displayed that in DEB-BACE group, CR was associated with improved ECOG score and longer MPE progression-free survival, and adverse events mainly included fever, chest distress/pain, gastrointestinal side effects, myelosuppression, rash and hemoptysis, which were all mild and tolerable. Conclusions DEB-BACE plus intercostals arterial infusion chemotherapy could serve as a salvage treatment option for NSCLC patients with refractory MPE.

Abstract
Background The treatment of malignant stenosis involving the carina or bronchi is challenging due to complicated anatomy with individual variation, which makes it necessary to customize stents for each patient. Therefore, this study aims to evaluate the feasibility of a novel metallic segmented airway stent customized with the aid of three-dimensional (3D) printing for such cases. Methods The stents were individually customized with the aid of a 3D printed mold based on computed tomography (CT) images according to the anatomical features of the airway. A segmented design was applied on the junction part of the main stem and the branches to fit the dynamic changes of the carina angle. In 12 patients with airway stenosis caused by malignancies including esophageal cancer (EC) and lung cancer (LC), the stents were implanted. The technical and clinical success of the stenting procedure, Hugh-Jones (HJ) classification, Karnofsky performance status (KPS), and stent-related complications of patients were evaluated. Results The stenting procedure was technically successful in all patients, and 11 patients showed significant palliation of dyspnea after stenting. The HJ and KPS classification of patients after stent insertion improved significantly compared with those before stenting (P=0.003 and P=0.006, respectively). During follow-up, granulation tissue proliferation and sputum retention were found in two and four patients, respectively. Conclusions This study shows that the implantation of a novel stent designed with the aid of 3D printing is feasible for relieving dyspnea and improving performance status of patients with inoperable malignant stenosis involving the carina or bronchi.

Abstract
BACKGROUND Hemorrhage is a life-threatening complication during bronchoscopic intervention in patients with central airway obstruction (CAO) due to metastatic renal cell carcinoma (RCC). Whether pre-bronchoscopic bronchial arterial embolization (BAE) can reduce the risk of severe bleeding in CAO patients due to metastatic RCC remains unclear. METHODS A total of 31 CAO patients due to metastatic RCC were included retrospectively and divided into a BAE group (receiving pre-bronchoscopic BAE) and non-BAE group in this study. Based on computed tomography (CT) and bronchoscopic findings, tumor debulking was used to reconstruct the airway during interventional bronchoscopy. The primary outcome was the incidence of severe bleeding during bronchoscopic procedures. Bleeding-related complications, Karnofsky performance score (KPS) and dyspnea score were also analyzed over a 1-month observation period. RESULTS There were no significant differences between the two groups in baseline characteristics, including patients' features, tumor morphology under CT scannings, tumor site, and obstruction degree under bronchoscopic examination. Procedure-related bleeding occurred in all 31 patients. Pre-bronchoscopic BAE significantly reduced the incidence of moderate and major bleeding when compared with that in the non-BAE group. The incidence of poor visualization and hypoxia was also reduced significantly in the BAE group. There was no significant difference in KPS and dyspnea score between the BAE and non-BAE groups at 1 month follow up. CONCLUSION Pre-bronchoscopic BAE might be a feasible option to reduce the risk of severe bleeding for CAO patients due to metastatic RCC during bronchoscopic intervention. Interventional bronchoscopy was a safe and effective procedure for CAO due to metastatic RCC.The reviews of this paper are available via the supplemental material section.

Abstract
OBJECTIVE MicroRNAs (miRNAs) have been found to play important roles in the development of non-small cell lung carcinoma (NSCLC). The aim of this study was to analyze the expression and clinical value of serum miR-185 in NSCLC. METHODS Serum miR-185 levels were detected in 146 NSCLC patients, 50 patients with carcinoma in situ, 25 patients with non-malignant lung diseases (NMLD), and 80 healthy controls using quantitative reverse transcription PCR. The correlation between serum miR-185 level and clinical status of NSCLC was explored. RESULTS The results revealed that serum miR-185 expression was progressively decreased in healthy controls, patients with NMLD, patients with carcinoma in situ and NSCLC patients. In addition, compared to carcinoembryonic antigen (CEA), serum miR-185 demonstrated better diagnostic accuracy for discriminating patients with carcinoma from healthy controls, NSCLC patients from healthy controls and NSCLC patients from patients with carcinoma in situ. In addition, serum miR-185 levels were significantly elevated in post-treated samples compared to the pre-treated samples. Moreover, reduced serum miR-185 was closely associated with unfavorable clinicopathological parameters and worse survival. Univariate and multivariate cox regression analysis confirmed that serum miR-185 was an independent prognostic indicator for NSCLC. CONCLUSIONS Collectively, our findings have demonstrated that serum miR-185 might serve as a promising and robust biomarker for the early detection and prognosis prediction of NSCLC.

Abstract
Theranostics in nuclear medicine refers to personalized patient management that involves targeted therapy and diagnostic imaging using a single or combination of radionuclide (s). The radionuclides emit both alpha (α) or beta (β-) particles and gamma (γ) rays which possess therapeutic and diagnostic capabilities, respectively. However, the production of these radionuclides often faces difficulties due to high cost, complexity of preparation methods and that the products are often sourced far from the healthcare facilities, hence losing activity due to radioactive decay during transportation. Subject to the availability of a nuclear reactor within an accessible distance from healthcare facilities, neutron activation is the most practical and cost-effective route to produce radionuclides suitable for theranostic purposes. Holmium-166 (166Ho), Lutetium-177 (177Lu), Rhenium-186 (186Re), Rhenium-188 (188Re) and Samarium-153 (153Sm) are some of the most promising neutron-activated radionuclides that are currently in clinical practice and undergoing clinical research for theranostic applications. The aim of this paper is to review the physical characteristics, current clinical applications and future prospects of these neutron activated radionuclides in theranostics. The production, physical properties, validated clinical applications and clinical studies for each neutron-activated radionuclide suitable for theranostic use in nuclear medicine are reviewed in this paper.

Abstract
Numerous studies have identified that microRNAs (miRs) play a crucial role in the tumorigenesis of non-small cell lung cancer (NSCLC). However, to the best of our knowledge, the physiological function of miR-103 in NSCLC is not fully understood. Experiments in the present study revealed that miR-103 expression was increased in NSCLC cell lines. In addition, a series of methods, including MTT, colony formation, 5-ethynyl-2′-deoxyuridine, Transwell, wound healing, flow cytometric, reverse transcription-quantitative PCR and western blot assays, were performed, which revealed that overexpression of miR-103 enhanced cell growth, migration, invasion and epithelial-mesenchymal transition (EMT), and suppressed apoptosis of A549 and H1299 cells. Additionally, a dual-luciferase reporter assay indicated that miR-103 directly targets the 3′-untranslated region of Kruppel-like factor 7 (KLF7), and KLF7 expression was negatively regulated by miR-103 expression. Furthermore, the present findings demonstrated that miR-103 promoted EMT via regulating the Wnt/β-catenin signaling pathway in NSCLC. Collectively, the current results demonstrated that miR-103 serves a tumorigenesis role in NSCLC development by targeting KLF7, at least partly via the Wnt/β-catenin signaling pathway. Consequently, these findings indicated that miR-103/KLF7/Wnt/β-catenin may provide a novel insight into underlying biomarkers for improving the diagnosis and treatment of NSCLC.

Abstract
In both men and women around the world, lung cancer accounts as the
principal cause of cancer-related death after breast cancer. Therefore, early detection of
the disease is a cardinal step in improving prognosis and survival of patients. Today, the
newly-defined microRNAs regulate about 30 to 60 percent of the gene expression.
Changes in microRNA Profiles are linked to numerous health conditions, making them
sophisticated biomarkers for timely, if not early, detection of cancer. Though evaluation
of microRNAs in real samples has proved to be rather challenging, which is largely
attributable to the unique characteristics of these molecules. Short length, sequence
similarity, and low concentration stand among the factors that define microRNAs.
Recently, diagnostic technologies with a focus on wide-scale point of care have recently
garnered attention as great candidates for early diagnosis of cancer. Electrochemical
nano-biosensors have recently garnered much attention as a molecular method,
showing great potential in terms of sensitivity, specificity and reproducibility, and last but
not least, adaptability to point-of-care testing. Application of nanoscale materials in
electrochemical devices as promising as it is, brings multiplexing potential for conducting
simultaneous evaluations on multiple cancer biomarkers. Thanks to their enthralling
properties, these materials can be used to improve the efficiency of cancer diagnostics,
offer more accurate predictions of prognosis, and monitor response to therapy in a more
efficacious way. This article presents a concise overview of recent advances in the
expeditiously evolving area of electrochemical biosensors for microRNA detection in
lung cancer.

Clinical and radiographic predictors of successful therapeutic bronchoscopy for the relief of malignant central airway obstruction. BMC Pulm Med 2019; 19:219. [PMID: 31752776 PMCID: PMC6873512 DOI: 10.1186/s12890-019-0987-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Accepted: 11/08/2019] [Indexed: 12/18/2022] Open
Abstract
Background Malignant central airway obstruction (CAO) occurs in approximately 20–30% of patients with lung cancer and is associated with debilitating symptoms and poor prognosis. Multimodality therapeutic bronchoscopy can relieve malignant CAO, though carries risk. Evidence to guide clinicians regarding which patients may benefit from such interventions is sparse. We aimed to assess the clinical and radiographic predictors associated with therapeutic bronchoscopy success in relieving malignant CAO. Methods We reviewed all cases of therapeutic bronchoscopy performed for malignant CAO at our institution from January 2010–February 2017. Therapeutic bronchoscopy success was defined as establishing airway patency of > 50%. Patient demographics and baseline characteristics, oncology history, degree of airway obstruction, procedural interventions, and complications were compared between successful and unsuccessful groups. Univariate and multivariate logistic regression identified the significant clinical and radiographic predictors for therapeutic success. The corresponding simple and conditional odds ratio were calculated. A time-to-event analysis with Kaplan–Meier plots was performed to estimate overall survival. Results During the study period, 301 therapeutic bronchoscopies were performed; 44 (14.6%) were considered unsuccessful. Factors associated with success included never vs current smoking status (OR 5.36, 95% CI:1.45–19.74, p = 0.010), patent distal airway on CT imaging (OR 15.11, 95% CI:2.98–45.83, p < 0.0001) and patent distal airway visualized during bronchoscopy (OR 10.77, 95% CI:3.63–31.95, p < 0.001) in univariate analysis. Along with patent distal airway on CT imaging, increased time from radiographic finding to therapeutic bronchoscopy was associated with lower odds of success in multivariate analysis (OR 0.96, 95% CI:0.92–1.00, p = 0.048). Median survival was longer in the successful group (10.2 months, 95% CI:4.8–20.2) compared to the unsuccessful group (6.1 months, 95% CI:2.1–10.8, log rank p = 0.015). Conclusions Predictors associated with successful therapeutic bronchoscopy for malignant CAO include distal patent airway visualized on CT scan and during bronchoscopy. Odds of success are higher in non-smokers, and with decreased time from radiographic finding of CAO to intervention.

Abstract
The present study aimed to evaluate microRNA- 20b-5p (miR-20b-5p) expression in non-small cell lung cancer (NSCLC), and investigate the effects of miR-20b-5p expression on NSCLC cell proliferation and migration. Reverse transcription-quantitative polymerase chain reaction was performed to measure the expression level of miR-20b-5p in NSCLC tissues and cell lines. Cell Counting Kit-8 and wound healing assays were used to measure cell proliferation and migration. A dual-luciferase reporter assay was performed to validate B-cell translocation gene 3 (BTG3) as a target of miR-20b-5p. It was identified that the expression level of miR-20b-5p is elevated in NSCLC tissues and cell lines. miR-20b-5p overexpression was revealed to promote NSCLC cell proliferation and migration. Furthermore, BTG3 was identified as a direct target of miR-20b-5p, and BTG3 overexpression reversed a miR-20b-5p mimic-induced increase in cell proliferation and migration. In summary, the present study revealed that miR-20b-5p promotes NSCLC cell proliferation and migration by targeting BTG3, which may assist with the development of a novel therapeutic target for the treatment of NSCLC.

Abstract
Interventional pulmonology (IP) has evolved in recent decades, and recent advances have greatly expanded the services offered by IP physicians. IP is best defined as the use of advanced techniques for the evaluation and treatment of benign and malignant pulmonary disorders. The field has further advanced with the recent establishment of a board certification via the American Association of Bronchology and Interventional Pulmonology and the release in 2017 of accreditation standards for specialized fellowship training. This article provides a broad overview of the field to serve as a resource for primary care physicians.

Abstract
Dysregulated microRNAs (miRNAs/miRs) directly modulate the biological functions of non‑small cell lung cancer (NSCLC) cells and contribute to the initiation and progression of NSCLC; however, the specific roles and underlying mechanisms of the dysregulated miRNAs in NSCLC require further investigation. The present study reported that miRNA‑629‑5p (miR‑629) was upregulated in NSCLC tissues and cell lines. High miR‑629 expression levels were significantly associated with tumour size, clinical stage and lymph node metastasis in patients with NSCLC. Functional experiments indicated that miR‑629 inhibition suppressed the viability and invasion NSCLC cells in vitro. Furthermore, bioinformatics prediction, luciferase reporter assay, reverse transcription‑quantitative polymerase chain reaction and western blot analysis demonstrated that runt‑related transcription factor 3 (RUNX3) was a direct target gene of miR‑629 in NSCLC. Restoration of RUNX3 expression suppressed the effects of miR‑629 inhibition in NSCLC cells. Rescue experiments revealed that RUNX3 knockdown partially abrogated the effects of miR‑629 inhibition on NSCLC cells. In summary, miR‑629 directly targeted RUNX3 to inhibit the progression of NSCLC, suggesting that this miRNA may be considered as a diagnostic and therapeutic target for patients with NSCLC.

Abstract
Numerous microRNAs (miRNA/miRs) have been reported to be associated with the initiation and progression of non‑small cell lung cancer (NSCLC). The aim of the present study was to examine the expression and biological role of miR‑939 in human NSCLC, in vitro. Reverse transcription‑quantitative polymerase chain reaction analysis was used to evaluate the expression of miR‑939 in NSCLC tissues. Cell Counting Kit‑8, 5‑ethynyl‑29‑deoxyuridine and Transwell assays were also used to determine the effects of miR‑939 on tumor cell proliferation and invasion in two human NSCLC cell lines (H1299 and SPCA1). Furthermore, tissue inhibitor of metalloproteinases 2 (TIMP2) was confirmed to be a target of miR‑939 by luciferase reporter assay, western blotting and bioinformatics analysis. Following downregulation of miR‑939 expression, cell proliferative and invasive abilities were significantly suppressed. Collectively, these findings indicated that the knockdown of miR‑939 may inhibit cell proliferation and invasion by regulating the expression of TIMP2 in NSCLC cells. Thus, miR‑939 may be a potential target in the treatment of NSCLC, although this requires further investigation.

Abstract
A systematic literature was performed to assess the benefit in terms of effectiveness and feasibility of hypofractionated radiotherapy (HypoRT), with or without chemotherapy (CT), in the treatment of locally advanced non-small cell lung cancer (NSCLC). We have identified all studies, published from 2007 onwards, on patients with locally advanced NSCLC treated with HypoRT with radical intent, with a minimal dose per fraction of 2.4 Gy, with or without concurrent chemotherapy. Twenty-nine studies were identified, for a total of 2614 patients. Patients were divided in the concurrent chemo-radiation therapy group (CT-RT) and radiotherapy alone (RT). In RT group, the delivered dose ranged from 45 to 85.5 Gy, with a dose/fraction from 2.4 to 4 Gy. Actuarial 2-year PFS ranged from 13 to 57.8%, and 1, 2- and 3-year overall survival (OS) ranged from 51.3 to 95%, from 22 to 68.7%, and from 7 to 32%, respectively. Acute Grade ≥ 3 esophagitis occurred in 0-15%, while late esophageal toxicity was 0-16%. Acute pneumonitis occured in 0-44%, whereas late pneumonitis occured in 0-47%, most commonly grade ≤ G3. In CT-RT group, the delivered dose ranged from 52.5 to 75 Gy, with a dose/fraction ranging from 2.4 to 3.5 Gy. Actuarial 2-year PFS ranged from 19 to 57.8%, and OS at 1, 2 and 3 years ranged from 28 to 95%, 38.6 to 68.7%, and 31 to 44%, respectively. Acute Grade 2 and 3 esophagitis occurred in 3-41.7%, while late esophageal toxicity occurred in 0-8.3%. Acute pneumonitis ranged from 0 to 23%, whereas late pneumonitis occured 0-47%. HypoRT seems to be safe in patients with locally advanced NSCLC. The encouraging survival results of several studies analyzed suggest that hypofractionated radiation schemes should be further investigated in the future.

MiR-21 and MiR-155 promote non-small cell lung cancer progression by downregulating SOCS1, SOCS6, and PTEN. Oncotarget 2018; 7:84508-84519.

Abstract
Lung cancer remains the leading cause of cancer-associated death worldwide. MiR-21 and miR-155 are the most amplified miRNAs in non-small cell lung carcinoma (NSCLC), and are critical promoters of NSCLC progression. However, it remains unclear how miR-21 and miR-155 induce cancer progression, and whether these miRNAs share common targets, such as tumor suppressor genes required to prevent NSCLC. Here we report that miR-21 and miR-155 levels are elevated in NSCLC and are proportional to the progression of the disease. In addition, miR-21 and miR-155 share nearly 30% of their predicted target genes, including SOCS1, SOCS6, and PTEN, three tumor suppressor genes often silenced in NSCLC. Consequently, antagonizing miR-21, miR-155 or both potently inhibited tumor progression in xenografted animal models of NSCLC. Treatment with miR-21 and miR-155 inhibitors in combination was always more effective against NSCLC than treatment with a single inhibitor. Furthermore, levels of miR-21 and miR-155 expression correlated inversely with overall and disease-free survival of NSCLC patients. Our findings reveal that miR-21 and miR-155 promote the development of NSCLC, in part by downregulating SOCS1, SOCS6, and PTEN. Combined inhibition of miR-21 and miR-155 could improve the treatment of NSCLC.

Abstract
Exploitation of autophagy might potentially improve therapeutic strategy. Here, we analyzed the protein expression of autophagy-associated genes including LC3A, LC3B, Beclin-1, p62, and Atg5 in 88–131 primary lung tumors by immunohistochemistry (IHC) on tissue-microarrays (TMAs). Additionally, the DNA methylation pattern of LC3A was investigated by bisulfite sequencing (BS) and methylation-specific-PCR (MSP). It turned out that the higher expression of LC3A protein was associated with adenocarcinoma compared to squamous cell carcinoma of lung (p = 0.008), positive staining of LC3B was significantly related to tumor grade (p = 0.006), and the protein expression of Beclin-1 was significantly correlated to pN stage (p = 0.041). The expression of p62 and Atg5 was however not significantly associated with any clinicopathological parameters. Downregulation of LC3A was related to DNA methylation in lung cancer cell lines, while in primary lung tumor samples, protein expression of LC3A was not significantly correlated with DNA methylation, and the methylation status of LC3A was not related to clinicopathological features. Taken together, our results suggest that autophagy-associated proteins such as LC3A, LC3B, and Beclin-1 might be potential biomarkers for subclassification, differentiation, and local metastasis in primary lung tumor, and epigenetic mechanism is partially responsible for gene silencing of LC3A in lung cancer cell lines.

Abstract
Gemcitabine (GEMZ) is the first-line therapy used against non-small cell lung cancer (NSCLC), and studies have focused on investigating the potential effects of agents combined with GEMZ to enhance the anticancer efficacy in NSCLC. Previous studies have reported that trichosanthin (TCS) has various physiological and pharmacological effects, including anti-human influenza virus enzymes, inhibition of protein synthesis and antitumor activity. The purpose of the present study was to investigate if TCS enhanced the antitumor effects of GEMZ in NSCLC. MTT assay demonstrated that TCS significantly enhanced the cytotoxic effect of GEMZ (P>0.05). Furthermore, a propidium iodide/Αnnexin V staining assay revealed that TCS exerted its pharmacological effect by increasing the apoptotic population. In addition, western blot analysis demonstrated that the combination treatment of TCS with GEMZ further decreased the expression level of phosphoinositide 3-kinase (PI3K) and AKT via regulating the expression of insulin growth factor. The results of the present study demonstrated that TCS enhanced the cytotoxic and apoptotic effects of GEMZ in A549 cells via regulating the PI3K/AKT pathway. In conclusion, these observations may provide a potential rational basis for a combination strategy for chemotherapy treatment of NSCLC.

Owing to its unique superiority in improving quality of life and prolonging survival time among advanced lung cancer patients, Chinese medicine (CM) has, in recent years, received increased attentions worldwide. We utilized a bibliometric statistical method based on MEDLINE/GoPubMed to conduct a comprehensive analysis of the current application status of CM in lung cancer, by including annual and accumulated publications, origin distribution of countries and journals, and keywords with a higher frequency score. Then the relevant clinical trials and mechanistic studies were systematically summarized within the field according to research types. We have raised potential problems and provided potentially useful reference information that could guide similar studies in the future. The basic experimental results are highly consistent with clinical trials, leading us to conclude that CM can offer better overall therapeutic benefits when used in combination with routine Western medicine for patients with advanced lung cancer.

[PMID: 27878971 PMCID: PMC5224856 DOI: 10.1002/cam4.960] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2016] [Revised: 08/24/2016] [Accepted: 09/04/2016] [Indexed: 12/19/2022] Open
Abstract
Cytochrome P450 2C8 (CYP2C8) is one of the enzymes that primarily participate in producing metabolisms of medications and P‐glycoprotein (P‐gp) has been regarded as one of the important molecules in chemotherapeutically induced multidrug resistance (MDR). In addition, the pregnane X receptor (PXR) is involved in regulating both CYP2C8 and P‐gp. We aim to research the effect of PXR on Taxol‐resistant non–small‐cell lung cancer (NSCLC cells) via regulating CYP2C8 and P‐gp. NSCLC cells were treated with SR12813, LY335979, or PXR siRNA. Cell counting kit (CCK‐8) assay was used to detect cell vitality. Colony formation assay was used to observe cell proliferation. Western blotting, real‐time polymerase chain reaction (RT‐PCR), and immunofluorescence staining were conducted to analyze the expressions of PXR, CYP2C8, and P‐gp. Taxol and its metabolic products were detected by high‐performance liquid chromatography (HPLC). The expression of PXR in A549 cell line was higher than that in other cell lines. The accumulation of PXR was observed in the nucleus after cells were treated with SR12813. Besides, SR12813 induced higher expressions of CYP2C8 and P‐gp proteins. We also discovered that pretreatment with SR12813 reversed the inhibition of cell viability and proliferation after the Taxol treatment in comparison to the SR12813 untreated group. Furthermore, the hydroxylation products of Taxol analyzed by HPLC were increased in comparison to the SR12813 untreated group, indicating that high expressions of CYP2C8 and P‐gp enhanced the resistance of A549 cells to Taxol. For cells treated with PXR siRNA, cell viability, cell proliferation, and Taxol metabolites were significantly reduced after the Taxol treatment in comparison to the siRNA‐negative group. The cell viability, cell proliferation, and Taxol metabolites were regulated by the expressions of PXR, P‐gp, and CYP2C8. That is, PXR expression has an important effect on the resistance of NSCLC cells to Taxol via upregulating P‐gp and CYP2C8.

Abstract
BACKGROUND Recurrent airway granulation hyperplasia and scar formation make airway stenosis a clinical challenge. Therefore, a new approach for the treatment of airway stenosis is necessary. OBJECTIVE To explore the inhibitory effect of β-elemene on the proliferation of fibroblasts and airway granulation. METHODS In vivo: (1) study of the effect of local β-elemene injection by bronchoscopy. (2) During bronchoscopy, granulation tissues both before and after treatment were obtained. HE staining was performed and the result compared. In vitro: (1) human airway primary fibroblasts were purified and characterized. (2) Fibroblasts were treated with β-elemene and normal saline (NS) and then examined by optical and electron microscopy. (3) Fibroblasts treated with β-elemene or NS were assessed for viability by tetrazolium salt assay. (4) Apoptotic rates were determined by flow cytometry. RESULTS In vivo: (1) after local injection of β- elemene, airway granulation tissue was reduced. (2) Granulation tissue was found to have less edema, and fibroblasts turned into mature fiber cells. In vitro: (1) human airway primary fibroblasts were successfully purified and cultured. (2) Compared with the control group, fibroblasts of the experimental group became clumped, the plasma granules were increased, and some fibroblasts lost their nucleus and organelles. (3) Compared with the control group, reduction of cell viability was detected with increased concentrations of β-elemene. (4) With increased concentrations of β-elemene, apoptotic rates of the fibroblasts were raised compared with the control group. CONCLUSIONS β-Elemene may induce apoptosis and necrosis of airway primary fibroblasts and inhibit the proliferation of fibroblasts and airway granulation. The results provide a new approach for the treatment of airway stenosis.

Abstract
PURPOSE OF REVIEW Patients with lung cancer often develop endobronchial disease, endobronchial tumor extension or airway compression. Various nonmalignant diseases can also lead to severe central airway obstruction.Since the early 1980s, technical advances of interventional bronchoscopic techniques have improved symptom-free survival and quality of life for patients with lung cancer. Apart from other techniques, various airway stents have been developed. Although interventional procedures are not definitive therapies, they often relieve the strangling sensation produced by airway occlusion. There have been various new developments and the authors review the available current literature on endobronchial stents RECENT FINDINGS For patients with respiratory symptoms because of malignant airway obstruction, stent placement provides symptom palliation and improved quality of life. SUMMARY Various options for central airway obstruction are in development and will change our daily work. In particular, coated stents have a large potential in minimizing stent complications.

Abstract
BACKGROUND Renal cell carcinoma is one of the major endobronchial metastases, and it occasionally causes life-threatening airway obstruction. Rigid bronchoscopy is useful as a palliative intervention; however, its utility for metastatic renal cell carcinoma has not been elucidated. The purpose of this study was to evaluate the safety and efficacy of rigid bronchoscopic treatment for endobronchial metastasis of renal cell carcinoma. METHODS Among 550 patients who underwent rigid bronchoscopic intervention at a single center from January 2005 to June 2015, 9 with metastatic renal cell carcinoma were retrospectively reviewed. Procedures were performed with rigid and flexible bronchoscopes under general anesthesia. RESULTS In total, 20 procedures were performed on 9 patients who underwent stent implantation. Bleeding was observed in 12 (60%) procedures while severe hypoxia was observed in 2 (10%). The required amount of supplemental oxygen successfully decreased after all the 10 procedures (100%) in patients who previously needed it. Median survival after the first procedure was of 260 days (range, 63-913 days). CONCLUSIONS Rigid bronchoscopic intervention for endobronchial metastasis of renal cell carcinoma is feasible with safety and effectiveness for palliation of airway obstruction, if one prepares sufficiently for massive intraoperative bleeding.

Abstract
PURPOSE Malignant pleural effusion (MPE) is common in patients with advanced cancer. Chemical pleurodesis can be considered for MPE that do not respond to chemotherapy, radiotherapy, or therapeutic thoracentesis. However, it is not yet clear which agent is more effective and safer in chemical pleurodesis. METHODS This study was designed as a single arm, multicenter, and open-label phase III clinical trial to evaluate efficacy and safety of chemical pleurodesis using mistletoe extraction (ABNOVAviscum(®) Injection). References of other agents in chemical pleurodesis were investigated to compare efficacy and safety. Efficacy was evaluated by followed up chest X-ray and changes of clinical symptoms and Karnofsky performance scale. Safety was evaluated by serious adverse event (SAE) and changes of laboratory findings. A follow-up period was 4 weeks after last pleurodesis. RESULTS Of 62 patients, 49 (79.0%) had complete response, 11 (17.7%) had partial response, and two had no response. Mean response rate was significantly different in this study comparing with reference response rate which was 64% (p <0.0001). There were two SAEs, but all were recovered without sequelas. CONCLUSION The results of this study suggest that mistletoe extraction (ABNOVAviscum(®) Injection) could be an effective and safe agent of chemical pleurodesis in patients with MPE.

Abstract
BACKGROUND The silicone Y-stent has mainly been used for the treatment of lesions around the main carina, and only a few case reports have been published on the technique for the lesions around the secondary left carina (LC2). OBJECTIVES We investigated the feasibility, efficacy and safety of a stenting technique using a silicone Y-stent for patients with airway stenosis around LC2. METHODS Patients who underwent airway stent placement between December 2010 and September 2014 in a single center were retrospectively reviewed. Under general anesthesia, using rigid and flexible bronchoscopes, the airway lumen was re-established followed by Y-stent placement on LC2. RESULTS We performed 274 airway stenting procedures for 253 patients during the study period. Twelve of them (7 with lung cancer, 3 with esophageal cancer/carcinosarcoma, 1 with thyroid cancer and 1 with renal cancer) underwent a Y-stent placement on LC2. Respiratory symptoms were relieved in all patients. Six of 7 patients with supplemental oxygen, including the mechanically ventilated patient before stent placement, could be discharged without supplemental oxygen. The chest radiograph after the procedure showed increased lung volume in all 7 patients with partial or complete atelectasis. Median survival after stenting was 197 days at the time of data collection. Retention of secretions occurred in 1 and hemoptysis in another patient. CONCLUSIONS Silicone Y-stent placement on LC2 is technically feasible, effective and acceptably safe.

Abstract
Malignant pleural effusion (MPE) is common and difficult to treat. In the vast majority of patients the presence of MPE heralds incurable disease, associated with poor quality of life, morbidity and mortality. Current therapeutic approaches are inefficient and merely offer palliation of associated symptoms. Recent scientific progress has shed light in the biologic processes governing the mechanisms behind the pathobiology of MPE. Pleural based tumors interfere with pleural fluid drainage, as well as the host vasculature and immune system, resulting in decreased fluid absorption and increased pleural fluid production via enhanced plasma extravasation into the pleural space. In order to achieve this feat, pleural based tumors must elicit critical vasoactive events in the pleura, thus forming a favorable microenvironment for tumor dissemination and MPE development. Such properties involve specific transcriptional signaling cascades in addition to secretion of important mediators which attract and activate host cell populations which, in turn, impact tumor cell functions. The dissection of the biologic steps leading to MPE formation provides novel therapeutic targets and recent research findings provide encouraging results towards future therapeutic innovations in MPE management.

Abstract
BACKGROUND The third-generation fully covered self-expandable metallic stent (SEMS) has been developed to solve the problems of difficult removal and in-stent granuloma formation related to the uncovered or partially covered type. There are few written reports about the performance of this type of stents with early encouraging results. OBJECTIVES To report and analyse our experience with the Silmet® stent in the management of malignant and benign tracheobronchial disorders. METHODS We retrospectively reviewed medical records of patients who underwent fully covered SEMS Silmet placement at the Interventional Pulmonology Unit, La Maddalena Cancer Center, Palermo, Italy, between May 2010 and August 2013. RESULTS Stents were placed in 52 patients with malignant (n = 49) and benign airway obstruction (n = 2) and broncho-oesophageal fistula (n = 1). SEMSs were inserted into the trachea (n = 19), the main bronchi (n = 21) and the peripheral bronchi (n = 31). Besides 1 procedural dislocation, the deployment was successful in all patients with an immediate significant improvement of symptoms (Barthel Index p < 0.001; Medical Research Council score p < 0.001). A radiographic improvement was detected in 48% of patients. The mean follow-up duration was 119 ± 120 days (range 22-549 days). Complications observed were: migration (7.6%), tumour overgrowth (15%), infections (5.7%), granulation tissue formation (3.8%) and mucus plug (3.8%). CONCLUSIONS The Silmet stent is effective, safe and simple to implant and remove. We suggest its use in cases of tight stenoses, in the treatment of small- to medium-caliber airways or in cases of tortuous airways.

Abstract
BACKGROUND Although concurrent chemoradiotherapy (CCRT) has become the standard approach for unresectable locally advanced non-small cell lung cancer (LA-NSCLC), most patients are not candidates for this treatment because of comorbidities. We evaluated the safety and efficacy of carbon ion radiotherapy (CIRT) in LA-NSCLC patients. METHODS Patients with stage IIA to IIIA (UICC 7th edition) LA-NSCLC were enrolled in a sequential phase I/II trial. For a phase I dose escalation study, the total prescribed dose was increased by 4 Gray equivalents (GyE) in 2 steps, from 68 to 72 GyE and then to 76 GyE, using 16 fractions over 4 weeks. After determining the recommended dose, the phase II trial was started in an expanded cohort. RESULTS Of the 36 patients treated in phase I, 2 grade 3 adverse events (radiation pneumonitis and tracheoesophageal fistula) were observed in the 76 GyE group. Accordingly, for phase II, the next consecutive 26 patients were treated with 72 GyE, with no grade 3 to 5 toxicities resulting. A total of 62 eligible patients were recruited. The majority of patients (49 of 62) were N0 or N1 patients, and the rest (13 of 62) were single-station N2 patients. The median follow-up period was 25.2 months. The 2-year local control rate (LCR) and overall survival (OS) for the entire cohort were 93.1% and 51.9%, respectively. In particular, patients with cT3-4N0 had an excellent prognosis; the 2-year OS and LCR were 69.3% and 100%, respectively. CONCLUSIONS Short-course CIRT monotherapy shows promise as an effective nonsurgical treatment for inoperable LA-NSCLC.

Abstract
Preanalytic sampling techniques and preparation of tissue specimens strongly influence analytical results in lung tissue diagnostics both on the morphological but also on the molecular level. However, in contrast to analytics where tremendous achievements in the last decade have led to a whole new portfolio of test methods, developments in preanalytics have been minimal. This is specifically unfortunate in lung cancer, where usually only small amounts of tissue are at hand and optimization in all processing steps is mandatory in order to increase the diagnostic yield. In the following, we provide a comprehensive overview on some aspects of preanalytics in lung cancer from the method of sampling over tissue processing to its impact on analytical test results. We specifically discuss the role of preanalytics in novel technologies like next-generation sequencing and in the state-of the-art cytology preparations. In addition, we point out specific problems in preanalytics which hamper further developments in the field of lung tissue diagnostics.

Abstract
Neodymium yttrium-aluminium-garnet (Nd : YAG) laser resection is one of the mostly used interventional pulmonology techniques for urgent desobstruction of malignant central airway obstruction (CAO). The major aim of this trial was to evaluate potential influence of Nd : YAG laser resection on overall quality of life (QoL) in patients with central lung cancer. Patients with malignant CAO scheduled for Nd : YAG laser resection were prospectively recruited in the trial. All patients were given European Organization for Research and Treatment, Quality of Life questionnaire (EORTC QLQ-30 v.3) before the procedure and approximately 2 weeks after the treatment. There were 37 male and 10 female patients, average age 54 ± 10 years. Most common tumour type was adenocarcinoma diagnosed in 51% of patients. Majority of patients were diagnosed in stage IIIB (53.2%) and stage IV (25.5%). Most common Eastern Cooperative Oncology Group performance status was 1 (72.3%). Nd : YAG laser resection significantly improved (P<0.0001) QoL and overall health according to EORTC QLQ-30. However, in some of the questions dealing with nausea, vomiting, diarrhoea, constipation, family life, social activities and financial situation, we did not observe statistically significant improvement. Nd : YAG laser resection of malignant CAO significantly improves QoL and overall health in patients with lung cancer.

[PMID: 25084400 PMCID: PMC4118890 DOI: 10.1371/journal.pone.0103698] [Citation(s) in RCA: 144] [Impact Index Per Article: 14.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2013] [Accepted: 07/07/2014] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND In South China (Gejiu City, Yunnan Province), lung cancer incidence and associated mortality rate is the most prevalent and observed forms of cancer. Lung cancer in this area is called Gejiu squamous cell lung carcinoma (GSQCLC). Research has demonstrated that overexpression of miR-21 occurs in many cancers. However, the unique relationship between miR-21 and its target genes in GSQCLC has never been investigated. The molecular mechanism involved in GSQCLC must be compared to other non-small cell lung cancers in order to establish a relation and identify potential therapeutic targets. METHODOLOGY/PRINCIPAL FINDINGS In the current study, we initially found overexpression of miR-21 occurring in non-small cell lung cancer (NSCLC) cell lines when compared to the immortalized lung epithelial cell line BEAS-2B. We also demonstrated that high expression of miR-21 could increase tumor cell proliferation, invasion, viability, and migration in GSQCLC cell line (YTMLC-90) and NSCLC cell line (NCI-H157). Additionally, our results revealed that miR-21 could suppress YTMLC-90 and NCI-H157 cell apoptosis through arresting cell-cycle at G2/M phase. Furthermore, we demonstrated that PTEN, RECK and Bcl-2 are common target genes of miR-21 in NSCLC. Finally, our studies showed that down-regulation of miR-21 could lead to a significant increase in PTEN and RECK and decrease in Bcl-2 at the mRNA and protein level in YTMLC-90 and NCI-H157 cell lines. However, we have not observed any remarkable difference in the levels of miR-21 and its targets in YTMLC-90 cells when compared with NCI-H157 cells. CONCLUSIONS/SIGNIFICANCE miR-21 simultaneously regulates multiple programs that enhance cell proliferation, apoptosis and tumor invasiveness by targeting PTEN, RECK and Bcl-2 in GSQCLC. Our results demonstrated that miR-21 may play a vital role in tumorigenesis and progression of lung squamous cell carcinoma and suppression of miR-21 may be a novel approach for the treatment of lung squamous cell carcinoma.

Abstract
Malignant pericardial effusion is one of the severe complications in advanced lung cancer patients, seriously affecting the patient's cardiopulmonary function and even life. Pericardial drainage and instillation of anti-neoplastic drugs in the pericardial cavity seems to offer the best chance of controlling pericardial effusion. We reported a case concerning treatment of a 63-year-old man in advanced lung cancer with a large amount of pericardial effusion. We utilized pericardium puncture and drainage combined with instillation of Cinobufacini injection in the pericardial cavity to treat pericardial effusion. After treatment with Cinobufacini injection for two weeks, the patient was followed up in one month to assess effectiveness, quality of life, and safety. We found that the cardiac tamponade symptoms such as difficult breathing, chest distress, and palpitations were significantly relieved. The patient's quality of life was effectively improved with KPS scores increased. We also found that the levels of tumor marker CA-125 in the pericardial effusion decreased (from 340.80 U/mL to 34.85 U/mL) and pericardium B ultrasound showed that the quantity of pericardial effusion reduced significantly (from 2.5 cm to 0.6 cm). Furthermore, there were little gastrointestinal adverse reactions and myelosuppression in the patient after instillation of the Cinobufacini injection. Taken together, this provides a new way for treating cancerous pericardial effusion, especially for patients who cannot tolerate instillation of chemotherapy drugs, and is worthwhile to carry out more standardized studies in the future.

Abstract
Approximately one-third of patients with lung cancer will develop airway obstruction and many cancers lead to airway obstruction through meta stases. The treatment of malignant airway obstruction is often a multimodality approach and is usually performed for palliation of symptoms in advanced lung cancer. Removal of airway obstruction is associated with improvement in symptoms, quality of life, and lung function. Patient selection should exclude patients with short life expectancy, limited symptoms, and an inability to visualize beyond the obstruction. This review outlines both the immediate and delayed bronchoscopic effect options for the removal of airway obstruction and preservation of airway patency with endobronchial stenting.

Abstract
Malignant pleural effusion (MPE) refers to the presence of neoplastic cells in the pleural fluid. Approximately 40 000 people per year in the UK are affected by MPE and it is associated with significant morbidity and an overall poor prognosis. Management should be prompt and care plans should be individualized and involve a multidisciplinary team of healthcare professionals. This article reviews the pathophysiology of MPE along with available investigations and management strategies for these patients.

Abstract
Minimally invasive diagnostic techniques are increasingly being used to obtain specimens for pathological diagnosis and prediction. Referring to lung cancer, both endobronchial and endoesophageal ultrasound are used worldwide as diagnostic routine methods. Consequently, an increasing number of pathological samples are cytological and fewer are histological. On the other hand, the requirements for specific and sensitive tumor subtyping complemented by predictive analyses are steadily increasing and are an essential basis for evidence-based treatment decisions. In this article we focus on the cell block method as a helpful tool for diagnostic and predictive analyses in lung cancer and point out its advantages and disadvantages in comparison to conventional cytological and biopsy specimens. Furthermore, we retrospectively analyze the diagnostic results of the cell block method in a high-volume center over 5 years. The main advantages of cell blocks are the availability of established and validated protocols, archiving and the opportunity to have serial sections from the same specimens to provide or repeat molecular analyses. Actually, in case of tumor progression, even additional biomarkers can be tested using the original cell block when re-biopsies are not feasible. The cell block method should be considered as a reliable, complimentary approach to conventional cytological or biopsy procedures, which is helpful to fulfill the increasing requirements of high-quality diagnostics and prediction.

Abstract
Survivin belongs to the family of apoptosis inhibitors (IAPs), which antagonizes the induction of cell death. Dysregulated expression of IAPs is frequently observed in cancers, and the high levels of survivin in tumors compared to normal adult tissues make it an attractive target for pharmacological interventions. The small imidazolium-based compound YM155 has recently been reported to block the expression of survivin via inhibition of the survivin promoter. Recent data, however, question that this is the sole and main effect of this drug, which is already being tested in ongoing clinical studies. Here, we critically review the current data on YM155 and other new experimental agents supposed to antagonize survivin. We summarize how cells from various tumor entities and with differential expression of the tumor suppressor p53 respond to this agent in vitro and as murine xenografts. Additionally, we recapitulate clinical trials conducted with YM155. Our article further considers the potency of YM155 in combination with other anti-cancer agents and epigenetic modulators. We also assess state-of-the-art data on the sometimes very promiscuous molecular mechanisms affected by YM155 in cancer cells.

Safety and effectiveness of microdebrider bronchoscopy for the management of central airway obstruction. Respirology 2013; 18:1011-5. [PMID: 23520982 DOI: 10.1111/resp.12087] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2012] [Revised: 01/27/2013] [Accepted: 01/29/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND AND OBJECTIVE Microdebrider bronchoscopy is a relatively new modality for the management of central airway obstruction (CAO) of both benign and malignant origin. Our objective was to describe our experience with this technique, with special attention to its safety and effectiveness. METHODS We retrospectively reviewed cases of therapeutic bronchoscopies using microdebrider for CAO from two institutions (M.D. Anderson Cancer Center and Michael E. Debakey VA Medical Center, Houston) from August 2008 through February 2012. RESULTS We identified 51 cases. Malignant CAO was detected in 36 cases (71%): non-small-cell lung cancer (n = 22), melanoma (n = 3), small-cell-lung cancer (n = 2), thyroid cancer (n = 2), esophageal carcinoma (n = 2), breast cancer (n = 2), and others (n = 3). Benign diseases included: papillomas (n = 8), granulation tissue (n = 3), and others (n = 4). Obstruction was purely endoluminal in 32 cases (63%). Pre-treatment obstruction was severe in 25 cases (49%), moderate in 20 cases (39%) and mild in 6 (12%). Lesions were located in the trachea (n = 23), main stem bronchi (n = 25), and bronchus intermedius (n = 8), with some patients having more than one lesion. After tumor debulking with microdebrider, the residual airway obstruction was insignificant (n = 27 cases; 53%), mild (n = 23 cases; 45%), and moderate (n = 1; 2%). No major complications were encountered, only 2 patients had mild adverse events: one case of pneumomediastinum, and one self-expandable stent damage requiring its removal. Two patients (4%) died within 30 days of causes unrelated to the procedure or the CAO. CONCLUSIONS Microdebrider bronchoscopy is a potentially safe and effective way to manage central airway obstruction of both malignant and benign origin.
