Abstract
This study aimed to compare the ability of narrow-band imaging to detect early and invasive lung cancer with that of conventional pathological analysis and white-light bronchoscopy. We searched the PubMed, EMBASE, Sinomed, and China National Knowledge Infrastructure databases for relevant studies. Meta-disc software was used to perform data analysis, meta-regression analysis, sensitivity analysis, and heterogeneity testing, and STATA software was used to determine if publication bias was present, as well as to calculate the relative risks for the sensitivity and specificity of narrow-band imaging vs those of white-light bronchoscopy for the detection of early and invasive lung cancer. A random-effects model was used to assess the diagnostic efficacy of the above modalities in cases in which a high degree of between-study heterogeneity was noted with respect to their diagnostic efficacies. The database search identified six studies including 578 patients. The pooled sensitivity and specificity of narrow-band imaging were 86% (95% confidence interval: 83-88%) and 81% (95% confidence interval: 77-84%), respectively, and the pooled sensitivity and specificity of white-light bronchoscopy were 70% (95% confidence interval: 66-74%) and 66% (95% confidence interval: 62-70%), respectively. The pooled relative risks for the sensitivity and specificity of narrow-band imaging vs the sensitivity and specificity of white-light bronchoscopy for the detection of early and invasive lung cancer were 1.33 (95% confidence interval: 1.07-1.67) and 1.09 (95% confidence interval: 0.84-1.42), respectively, and sensitivity analysis showed that narrow-band imaging exhibited good diagnostic efficacy with respect to detecting early and invasive lung cancer and that the results of the study were stable. Narrow-band imaging was superior to white light bronchoscopy with respect to detecting early and invasive lung cancer; however, the specificities of the two modalities did not differ significantly.

Abstract
The recent advances in diagnostic pulmonary procedures have revolutionized the evaluation of abnormal thoracic findings including lung nodules and masses, mediastinal lymphadenopathy, and pleural diseases. Bronchoscopies with endobronchial ultrasonography and electromagnetic navigation are examples of new technology that has significantly improved the specificity and sensitivity of these procedures in diagnosis and staging of lung cancer without the need for more invasive procedures. This report describes the different diagnostic pulmonary interventions providing a description of the procedures, their indications, diagnostic yield and drawback.

Abstract
BACKGROUND Bronchial intraepithelial lesions may be precursors of central airway lung carcinomas. Identification and early treatment of these preinvasive lesions might prevent progression to invasive carcinoma. METHODS We systematically reviewed the literature to develop evidence-based recommendations regarding the diagnosis and treatment of intraepithelial lesions. RESULTS The risk and timeline for progression of bronchial intraepithelial lesions to carcinoma in situ (CIS) or invasive carcinoma are not well understood. Multiple studies show that autofluorescence bronchoscopy (AFB) is more sensitive that white light bronchoscopy (WLB) to identify these lesions. In patients with severe dysplasia or CIS in sputum cytology who have chest imaging studies showing no localizing abnormality, we suggest use of WLB; AFB may be used as an adjunct when available. Patients with known severe dysplasia or CIS of central airways should be followed with WLB or AFB, when available. WLB or AFB is also suggested for patients with early lung cancer who will undergo resection for delineation of tumor margins and assessment of synchronous lesions. However, AFB is not recommended prior to endobronchial therapy for CIS or early central lung cancer. Several endobronchial techniques are recommended for the treatment of patients with superficial limited mucosal lung cancer who are not candidates for resection. CONCLUSION Additional information is needed about the natural history and rate of progression of preinvasive central airway lesions. Patients with severe dysplasia or CIS may be treated endobronchially; however, it remains unclear if these therapies are associated with improved patient outcomes.

Abstract
The role of autofluorescence bronchoscopy (AFB) was primarily investigated in regard to the detection of precancerous lesions of bronchial mucosa. Most of the results confirmed higher sensitivity for the detection of precancerous bronchial lesions, when compared to white light bronchoscopy (WLB) alone. However, it is commonly known that the specificity of AFB remains low. Our findings agree in terms of the detection of premalignant bronchial lesions and early lung cancer, but regarding the detection of synchronous lesions or in the evaluation of lung cancer extension, the specificity of AFB is significantly higher. There is still an ongoing debate in the scientific community whether or not autofluorescence should be used as a screening tool for lung cancer. Results of the majority of published series did not support the general use of AFB as a screening tool for lung cancer; however, these results suggest its use in groups of patients with a high risk of lung cancer. Despite this, some authors still do not recommend its use even in high-risk cases. In recent years, the indications for AFB have been widening and this tool may find its place in routine bronchoscopy. With new indications for AFB, such as the evaluation of tumor extension or follow up after surgical resection, bronchoscopists may make use of this tool more often. A sharp learning curve and a clear distinction between healthy and pathologically altered mucosa make this technology acceptable for inexperienced bronchoscopists. We also investigate new hardware and software improvements in AFB. The addition of backscattered light analysis, ultraviolet spectra, fluorescence-reflectance or dual digital systems could improve the diagnostic yield of this technology.

Abstract
BACKGROUND The purpose of this paper was to compare the sensitivity, specificity, and overall diagnostic performance of autofluorescence imaging bronchoscopy (AFI) versus white light bronchoscopy (WLB) in the detection of lung cancers and precancerous lesions by meta-analysis. METHODS We performed a literature search using the PubMed and EMBASE databases to identify studies published between March 1991 and March 2012. Article selection, quality assessment, and data extraction were then performed. The pooled sensitivity, specificity, diagnostic odds ratio, and area under the curve of the summary receiver operating characteristic for AFI versus WLB were calculated using Stata version 12.0 software. RESULTS Six studies were included in the meta-analysis. The pooled sensitivity of AFI and WLB was 0.89 (95% confidence interval [CI] 0.81-0.94) and 0.67 (95% CI 0.46-0.83) and the pooled specificity of AFI and WLB was 0.64 (95% CI 0.37-0.84) and 0.84 (95% CI 0.74-0.91), respectively. The diagnostic odds ratio for AFI and WLB was 14.5 (95% CI 3.76-55.63) and 10.9 (95% CI 3.12-38.21), and the area under the curve for AFI and WLB was 0.89 (95% CI 0.86-0.92) and 0.85 (95% CI 0.81-0.88), respectively. The pooled positive and negative likelihood ratios were 2.5 (95% CI 1.21-4.97) and 0.17 (95% CI 0.08-0.36) for AFI, and the corresponding values for WLB were 4.3 (95% CI 2.13-8.52) and 0.39 (95% CI 0.21-0.73). The pooled positive likelihood ratio for AFI and WLB was not higher than 10, and the pooled negative likelihood ratio for AFI and WLB was not lower than 0.1. CONCLUSION The sensitivity of AFI is higher than that of WLB, while the specificity of AFI is lower than that of WLB. The overall diagnostic performance of AFI is slightly better than that of WLB in detecting lung cancers and precancerous lesions. AFI should find its place in routine bronchoscopic examination and may improve the diagnostic outcome on endoscopy.

Abstract
Autofluorescence imaging videobronchoscopy (AFI) is one of the new systems of autofluorescence bronchoscopy designed for thorough examination of bronchial mucosa. The integration of autofluorescence and videobronchoscopy provides clear images of normal and pathologically altered bronchial mucosa. Major indications for AFI include evaluation of early-stage lung cancer and detection of precancerous lesions. However, in recent years, the indications for AFI are widening, and this tool might find its place in routine daily bronchoscopic practice. With new indications for AFI, such as evaluation of tumor extension or follow-up after surgical resection, this tool might be more often used by bronchoscopists. A sharp learning curve and clear distinction between healthy and pathologically altered mucosa make this technology acceptable for young and inexperienced bronchoscopists. One of the major disadvantages of AFI is low specificity in the detection of premalignant lesions and early-stage lung cancer. This disadvantage could be overcome with the appearance of new and improved technologies in autofluorescence, such as the addition of backscattered light analysis, ultraviolet spectra, fluorescence-reflectance or dual digital systems. Quantitative image analysis is also one of the ways to improve objectivity and minimize observer errors. However, one of the most appropriate solutions would be the addition of AFI to narrow band imaging, and merging the two technologies into one videobronchoscope.

Abstract
OBJECTIVES Determination of specificity and sensitivity of narrow band imaging (NBI) in the assessment of tumor extension in centrally located lung cancer, when compared to white light bronchoscopy (WLB) alone, and evaluation of possible influence of NBI on therapeutic decision in patients with lung cancer. PATIENTS AND METHODS We evaluated 36 patients with suspected lung cancer. All patients underwent WLB followed by NBI bronchoscopy. We were using videobronchoscope BF-1T180 and EVIS LUCERA SPECTRUM processor unit. RESULTS Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for NBI in the assessment of tumor extension were 97.8, 85, 93.7, and 94.4%, respectively; and for WLB 92.3, 60, 69.6, and 88.9%, respectively. In 14 patients, NBI revealed more extensive tumor than WLB (p =.0057). In eight patients, NBI showed significant influence on therapeutic decision (p =.001). CONCLUSION NBI videobronchoscopy had better specificity and sensitivity in the assessment of tumor extension in centrally located lung cancer, and it might play a significant role in the therapeutic decision.

Abstract
The major objective of our study was to determine the specificity and sensitivity of AFI videobronchoscopy vs. white light videobronchoscopy, in the assessment of lung cancer extent. Secondary objective was to investigate whether or not AFI can reveal greater extension of the tumor, and can it influence therapy making decision. Autofluorescence videobronchoscopy systems are new technology for visualization of bronchial mucosa, and the proper indications for such systems will be determined in the near future. In this prospective trial we have enrolled 27 patients with suspected lung cancer in whom we performed 108 diagnostic biopsies and 54 control biopsies. All patients underwent WL videobronchoscopy followed by Auto Fluorescence Imaging (AFI) examination of tracheobronchial tree. We were using videobronchoscope BF-F260 and EVIS LUCERA SPECTRUM processor unit. Overall specificity for AFI in the diagnostics of lung cancer was found to be 85%, sensitivity was 90%, positive predictive value (PPV) 78%, and negative predictive value (NPV) 94%. Specificity, sensitivity, PPV, and NPV for WL videobronchoscopy in lung cancer diagnostics were 54%, 64%, 51%, and 69%, respectively. Relative sensitivity ratio of AFI over WL videobronchoscopy, which is calculated to be 1.41, confirmed superiority of AFI in lung cancer diagnostics. We confirmed significant correlation between the greater extension of the tumor (assessed with AFI) and the therapeutical decision in lung cancer treatment (p = 0.01). Influence of AFI on therapeutical decision was significant (p = 0.034). AFI videobronchoscopy system yields significantly higher sensitivity and specificity for the assessment of lung cancer extent than WLB videobronchoscopy alone. It had shown to be able to influence therapeutic option for lung cancer treatment. Further studies are needed to evaluate and validate these results.

Abstract
BACKGROUND An evidence-based approach is necessary for the localization and management of intraepithelial and microinvasive non-small cell lung cancer in the central airways. METHODS Material appropriate to this topic was obtained by literature search of a computerized database. Recommendations were developed by the writing committee and then reviewed by the entire guidelines panel. The final recommendations were made by the Chair and were voted on by the entire committee. RESULTS White light bronchoscopy has diagnostic limitations in the detection of microinvasive lesions. Autofluorescence bronchoscopy (AFB) is a technique that has been shown to be a sensitive method for detecting these lesions. In patients with moderate dysplasia or worse on sputum cytology and normal chest radiographic findings, bronchoscopy should be performed. If moderate/severe dysplasia or carcinoma in situ (CIS) is detected in the central airways, then bronchoscopic surveillance is recommended. The use of AFB is preferred if available. In a patient being considered for curative endobronchial therapy to treat microinvasive lesions, AFB is useful. A number of endobronchial techniques as therapeutic options are available for the management of CIS and can be recommended to patients with inoperable disease. In patients with operable disease, surgery remains the mainstay of treatment, although patients may be counseled about these techniques. CONCLUSIONS AFB is a useful tool for the localization of microinvasive neoplasia. A number of endobronchial techniques available for the curative treatment can be considered first-line therapy in inoperable cases. For operable cases, the techniques may be considered and discussed with the patients.

Abstract
BACKGROUND We had previously developed the possibility of use of a photodynamic diagnosis (PDD) system using a tumor-selective photosensitizer and laser irradiation for the early detection and photodynamic therapy (PDT) for centrally located early lung cancers. Recently, we established the autofluorescence diagnosis system integrated into a videoendoscope (SAFE-3000) as a very useful technique for the early diagnosis of lung cancer. PATIENTS AND METHODS Twenty-nine patients (38 lesions) with centrally located early lung cancer received PDD and PDT using the second-generation photosensitizer, talaporfin sodium (NPe6). Just before the PDT, we defined the tumor margin accurately using the novel PDD system SAFE-3000 with NPe6 and a diode laser (408nm). RESULTS Red fluorescence emitted from the tumor by excitation of the photosensitizer by the diode laser (408nm) from SAFE-3000 allowed accurate determination of the tumor margin just before the PDT. The complete remission (CR) rate following NPe6-PDT in the cases with early lung cancer was 92.1% (35/38 lesions). We also confirmed the loss of red fluorescence from the tumors immediately after the PDT using SAFE-3000. We confirmed that all the NPe6 in the tumor had been excited and photobleached by the laser irradiation (664nm) and that no additional laser irradiation was needed for curative treatment. CONCLUSIONS This novel PDD system using SAFE-3000 and NPe6 improved the quality and efficacy of PDT and avoided misjudgement of the dose of the photosensitizer or laser irradiation in PDT. PDT using NPe6 will become a standard option of treatments for centrally located early lung cancer.

Abstract
Due to advances in interventional bronchoscopy, curative treatment has become possible for central type lung cancer if it is detected in the early stage. However, expertise is required to diagnose the extent of tumor invasion and the depth of tumor involvement by conventional white light bronchoscopy alone, but judgement is still subjective. The development of autofluorescence bronchoscopy (AFB) and endobronchial ultrasonography (EBUS) has had a large impact on diagnostic bronchoscopy in the past decade and have been employed especially for the diagnosis of central type tumors. Objective evaluation by a comprehensive approach using AFB, EBUS and optical coherence tomography (OCT) enables selection of the optimal therapeutic strategy for central type early lung cancer (CELC).

Abstract
The combination of white light and autofluorescence bronchoscopy has been reported to show better sensitivity in detecting dysplasia and cancer of the bronchus than white light alone. However, fiberoptic bronchoscopy has been replaced by videoendoscopy at most leading facilities for over a decade. To avoid interruption of the videoendoscopy examination to perform fiberscopy-based autofluorescence examination as well as enhancing the sensitivity of intraepithelial lesions, autofluorescence diagnosis system integrated into a videoendoscope (SAFE 3000, Pentax, Tokyo) was created. A total of 154 consecutive patients were studied using this system, containing 83 known or suspected lung cancer cases, 46 of the cases with abnormal sputum cytology findings, 10 follow up cases following lung cancer operations, and 15 heavy smokers with respiratory symptoms. Abnormal findings were recognized by white light and/or SAFE 3000 at 166 sites and biopsies were taken to evaluate the relationship between endoscopic findings and pathology results. The sensitivity of the system for CIS+dysplasia was 65% in white light and 90% in SAFE. This videoendoscopy-based autofluorescence system had significantly higher sensitivity for intraepithelial lesions than white light videoendoscopy alone.
