Efficacy of endoscopic surveillance for pharyngeal mucosa during endoscopic resection for pharyngeal carcinoma: a multicenter prospective study. Surg Endosc 2024; 38:2497-2504.

Abstract
INTRODUCTION Since patients with pharyngeal squamous cell carcinoma (SCC) often have multiple pharyngeal lesions, evaluation of pharyngeal lesions before endoscopic resection (ER) is important. However, detailed endoscopic observation of the entire pharyngeal mucosa under conscious sedation is difficult. We examined the usefulness of endoscopic surveillance with narrow band imaging (NBI) and lugol staining for detection of pharyngeal sublesions during ER for pharyngeal SCC under general anesthesia (endoscopic surveillance during treatment; ESDT). METHODS From January 2021 through June 2022, we examined 78 patients who were diagnosed with superficial pharyngeal SCC and underwent ER. They underwent the ESDT and for patients who were diagnosed with new lesions of pharyngeal SCC or high-grade dysplasia (HGD) that were not detected in the endoscopic examination before treatment, ER were performed simultaneously for new lesions and the main lesions. The primary endpoint of this study was the detection rate of new lesions of pharyngeal SCC or HGD in the ESDT. RESULTS Fifteen of the 78 patients were diagnosed as having undetected new pharyngeal lesions in the ESDT and 10 (12.8%) (95% CI 6.9-22.2%) were histopathologically confirmed to have new lesions of pharyngeal SCC or HGD. Among the 13 lesions of SCC or HGD, 8 were found by NBI observation; however, 5 were undetectable using NBI but detectable by lugol staining. All of the 13 lesions had endoscopic findings of pink color sign on lugol staining. CONCLUSIONS Endoscopic surveillance for pharyngeal sublesions during ER for pharyngeal SCC is feasible and useful.

Abstract
Recent advancements in endoscopy equipment have facilitated endoscopists’ detection of neoplasms in the oral cavity and pharyngolaryngeal regions. In particular, image-enhanced endoscopy using narrow band imaging or blue laser imaging play an integral role in the endoscopic diagnosis of oral and pharyngolaryngeal cancers. Despite these advancements, limited studies have focused on benign lesions that can be observed during esophagogastroduodenoscopy in the oral and pharyngolaryngeal regions. Therefore, this mini-review aimed to provide essential information on such benign lesions, along with representative endoscopic images of dental caries, cleft palate, palatal torus, bifid uvula, compression by cervical osteophytes, tonsil hyperplasia, black hairy tongue, oral candidiasis, oral and pharyngolaryngeal ulcers, pharyngeal melanosis, oral tattoos associated with dental alloys, retention cysts, papilloma, radiation-induced changes, skin flaps, vocal cord paresis, and vocal fold leukoplakia. Whilst it is imperative to seek consultation from otolaryngologists or dentists in instances where the diagnosis cannot be definitively ascertained by endoscopists, the merits of attaining foundational expertise pertaining to oral and pharyngolaryngeal lesions are unequivocal. This article will be a valuable resource for endoscopists seeking to enhance their understanding of oral and pharyngolaryngeal lesions.

Auris Nasus Larynx 2023; 50:423-429. [PMID: 36229311 DOI: 10.1016/j.anl.2022.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 08/23/2022] [Accepted: 09/26/2022] [Indexed: 04/03/2023]
Abstract
OBJECTIVE Esophageal cancer is the most common second primary cancer (SPC) in patients with head and neck cancer (HNC). Esophageal SPC has a negative impact on survival. Elevated mean corpuscular volume (MCV) is an accepted predictor of esophageal cancer risk. The aim of this study was to elucidate the usefulness of elevated MCV as an indicator of a high risk for esophageal SPC. METHODS We retrospectively reviewed the medical records of patients with oropharyngeal, hypopharyngeal, and laryngeal squamous cell carcinoma who underwent chemoradiotherapy between 2003 and 2012. We excluded patients younger than 20 years or who had received treatment for esophageal cancer and who had a histologically unproven lesion. Patients were divided into two groups according to their MCV. The cut-off for MCV was defined by receiver operating characteristics curve analysis. The primary endpoint was the cumulative incidence of esophageal SPC. RESULTS A total of 295 patients were included. The median follow-up period for surviving patients was 7.4 years and the optimal cut-off point was 99.0 fL. One hundred ninety-five patients (66%) had an MCV < 99.0 fL and 100 (34%) had an MCV ≥ 99.0 fL. The 5-year cumulative incidence in patients with an MCV < 99.0 fL and ≥ 99.0 fL was 8.7% and 27%, respectively. In the multivariate analysis, an MCV ≥ 99.0 fL (HR=2.2; 95%CI, 1.1-4.2) was an independent risk factor. CONCLUSION MCV ≥ 99.0 fL was found to be a risk factor for esophageal SPC. We, therefore, recommend that patients with an MCV ≥ 99.0 fL should undergo intensive monitoring.

Abstract
BACKGROUND The entire pharynx should be observed endoscopically to avoid missing pharyngeal lesions. An artificial intelligence (AI) model recognizing anatomical locations can help identify blind spots. We developed and evaluated an AI model classifying pharyngeal and laryngeal endoscopic locations. METHODS The AI model was trained using 5382 endoscopic images, categorized into 15 anatomical locations, and evaluated using an independent dataset of 1110 images. The main outcomes were model accuracy, precision, recall, and F1-score. Moreover, we investigated focused regions in the input images contributing to the model predictions using gradient-weighted class activation mapping (Grad-CAM) and Guided Grad-CAM. RESULTS Our AI model correctly classified pharyngeal and laryngeal images into 15 anatomical locations, with an accuracy of 93.3%. The weighted averages of precision, recall, and F1-score were 0.934, 0.933, and 0.933, respectively. CONCLUSION Our AI model has an excellent performance determining pharyngeal and laryngeal anatomical locations, helping endoscopists notify of blind spots.

Efficacy of a new traction method using ring-shaped thread for endoscopic submucosal dissection in the pharynx. Esophagus 2023; 20:256-263.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is a minimally invasive treatment for pharyngeal cancers. However, pharyngeal ESD is sometimes technically challenging because of the narrow and complex space in which to work. Traction is important to complete the procedure efficiently. Here, we report the technical details and efficacy of a new traction method for pharyngeal ESD using ring-shaped thread and grasping forceps. METHODS We analyzed pharyngeal ESD performed between January 2016 and March 2021 at our Institute. We designated cases resected using ring-shaped threads "Group R" and those resected without ring-shaped threads as conventional "Group C", and compared the technical outcomes between them. Multivariate analysis and the inverse probability treatment weighting (IPTW) method using propensity scores were adjusted by confounding variables. RESULTS We analyzed 89 lesions from 68 patients, of which 46 were in Group R and 43 in Group C. Median procedure time and median dissection speed were significantly shorter in Group R than C (37 min vs. 55 min, and 16.0 mm2/min vs. 7.0 mm2/min, respectively, both P < 0.05). These results were confirmed by both multivariate analysis and after IPTW adjustment. All lesions were resected en bloc, and the complete resection rate was not significantly different between Group R and C (91.3% vs. 79.1%, P = 0.14). There were no treatment-related adverse events in either group. CONCLUSIONS The traction method using ring-shaped thread increases the efficiency of pharyngeal ESD. This simple new traction method should be a useful option for pharyngeal ESD.

Abstract
Head and neck cancer is among the top ten cancers worldwide, with most lesions in the oral cavity. Oral squamous cell carcinoma (OSCC) accounts for more than 90% of all oral malignancies and is a significant public health concern. Patients with OSCC are at increased risk for developing concomitant tumors, especially in the oral cavity, due to widely genetically susceptible mucosa to carcinogenic factors. Based on fulfilling specific criteria, these concomitant tumors can be called second primary tumors (SPTs), which can be further categorized into metachronous and synchronous tumors. This research reviews the literature that investigated the concurrent OSCC with second or multiple primaries to improve understanding of the definition, classification guidelines, and its effect on cancer survival. It also highlights the current investigation methods, the variation of standard treatment approaches due to such a phenomenon, and preventive measures discussed in the literature.

Abstract
Esophagogastroduodenoscopy (EGD) is performed to rule out organic diseases in the diagnosis of esophageal motility disorders (EMDs). Abnormal endoscopic findings can be observed during EGD, which indicate the presence of EMDs. Several endoscopic findings at both the esophagogastric junction and esophageal body that are related to EMDs have been reported. Gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) could be detected during EGD, and these diseases are often associated with abnormal esophageal motility. Image-enhanced endoscopy (IEE) could improve the detection of these diseases during EGD. Although no report has been published previously on the potential usefulness of IEE in the endoscopic diagnosis of EMDs, IEE can be used to detect disorders that can be associated with abnormal esophageal motility.

Intraoperative Imaging Techniques to Improve Surgical Resection Margins of Oropharyngeal Squamous Cell Cancer: A Comprehensive Review of Current Literature. Cancers (Basel) 2023; 15:cancers15030896.

Abstract
Inadequate resection margins in head and neck squamous cell carcinoma surgery necessitate adjuvant therapies such as re-resection and radiotherapy with or without chemotherapy and imply increasing morbidity and worse prognosis. On the other hand, taking larger margins by extending the resection also leads to avoidable increased morbidity. Oropharyngeal squamous cell carcinomas (OPSCCs) are often difficult to access; resections are limited by anatomy and functionality and thus carry an increased risk for close or positive margins. Therefore, there is a need to improve intraoperative assessment of resection margins. Several intraoperative techniques are available, but these often lead to prolonged operative time and are only suitable for a subgroup of patients. In recent years, new diagnostic tools have been the subject of investigation. This study reviews the available literature on intraoperative techniques to improve resection margins for OPSCCs. A literature search was performed in Embase, PubMed, and Cochrane. Narrow band imaging (NBI), high-resolution microendoscopic imaging, confocal laser endomicroscopy, frozen section analysis (FSA), ultrasound (US), computed tomography scan (CT), (auto) fluorescence imaging (FI), and augmented reality (AR) have all been used for OPSCC. NBI, FSA, and US are most commonly used and increase the rate of negative margins. Other techniques will become available in the future, of which fluorescence imaging has high potential for use with OPSCC.

Abstract
Background and study aims Endoscopic submucosal dissection (ESD) of pharyngeal cancers with conventional endoscopes often is difficult, not only because of the narrow working space, but also because endoscope maneuverability in the pharynx is poor due to interference from the endotracheal tube and/or hyoid bone. However, we hypothesized that those problems could possibly be resolved by use of an ultrathin endoscope for ESD of superficial pharyngeal cancer. The aim of this prospective interventional study was to investigate the feasibility of ESD for superficial pharyngeal cancer using an ultrathin endoscope. Patients and methods This feasibility study was conducted at NTT Medical Center Tokyo between June 2020 and September 2021, and data from a total of 20 consecutively superficial pharyngeal cancers were analyzed. The primary outcome measure was the R0 resection rate. The ESD completion rate, en bloc resection rate, procedure time, and frequency of intraoperative and postoperative adverse events (AEs) were also evaluated as secondary outcome measures. Results Data from 16 patients with 20 lesions were included in the analysis. All of the lesions were successfully resected by ultrathin endoscope ESD, and the en bloc and R0 resection rates were 100 % and 85.0 % (17/20), respectively; the procedure time was 37.8 ± 28.2 minutes. No intraoperative or postoperative AEs were encountered in any cases. Conclusions ESD using an ultrathin endoscope is feasible for superficial pharyngeal cancers and has potential to be a safe and effective treatment option for these cancers.

Abstract
Abstract
Objectives
Understanding the miss rate and characteristics of missed pharyngeal and laryngeal cancers during upper gastrointestinal endoscopy may aid in reducing the endoscopic miss rate of this cancer type. However, little is known regarding the miss rate and characteristics of such cancers. Therefore, the aim of this study was to investigate the upper gastrointestinal endoscopic miss rate of oro-hypopharyngeal and laryngeal cancers, the characteristics of the missed cancers, and risk factors associated with the missed cancers.
Methods
Patients who underwent upper gastrointestinal endoscopy and were pathologically diagnosed with oro-hypopharyngeal and laryngeal squamous cell carcinoma from January 2019 to November 2020 at our institution were retrospectively evaluated. Missed cancers were defined as those diagnosed within 15 months after a negative upper gastrointestinal endoscopy.
Results
A total of 240 lesions were finally included. Eighty-five lesions were classified as missed cancers, and 155 lesions as non-missed cancers. The upper gastrointestinal endoscopic miss rate for oro-hypopharyngeal and laryngeal cancers was 35.4%. Multivariate analysis revealed that a tumor size of <13 mm (odds ratio: 1.96, P=0.026), tumors located on the anterior surface of the epiglottis/valleculae (odds ratio: 2.98, P=0.045) and inside of the pyriform sinus (odds ratio: 2.28, P=0.046) were associated with missed cancers.
Conclusions
This study revealed a high miss rate of oro-hypopharyngeal and laryngeal cancers during endoscopic observations. High-quality upper gastrointestinal endoscopic observation and awareness of missed cancer may help reduce this rate.

Abstract
Patients with superficial head and neck squamous cell carcinoma (HNSCC) can be completely treated by techniques of transoral surgery (TOS). The aim of this study was to evaluate the risk of metachronous multiple HNSCC arising after TOS based on alcohol dehydrogenase 1B (ADH1B) and aldehyde dehydrogenase 2 (ALDH2). We registered patients who underwent TOS for superficial HNSCC. Buccal cell samples were obtained by using a cotton swab to examine two single nucleotide polymorphisms in ADH1B and ALDH2 genotyping. We used Cox proportional hazards models to examine the risk of metachronous HNSCC. A total of 198 patients who underwent TOS for HNSCC were evaluated. In multivariate analysis, risks for second HNSCC were ADH1B*1/*1 [hazard ratio (HR), 1.88; 95% confidence interval (CI), 1.11-3.19; P = 0.02], ALDH2*1/*2 (HR, 2.11; 95% CI, 1.00-5.16; P = 0.048) and alcohol consumption before TOS (HR, 1.17; 95% CI, 1.06-1.27; P = 0.01). The 5-year incidence rates of second primary HNSCC in the temperance group and the non-temperance group were 20.8 and 46.5%, respectively (HR, 0.54; 95% CI, 0.31-0.92; P = 0.02). Cumulative development rates of third HNSCC in the temperance group and non-temperance group at 10 years were 11.3 and 36.1%, respectively (HR, 0.19; 95% CI, 0.03-0.65; P = 0.006). ADH1B*1/*1, ALDH2*1/*2 and moderate or heavy alcohol consumption before treatment are independent risk factors of metachronous HNSCC. Since it was shown that temperance decreased the incidences of second and third metachronous HNSCC, advice to discontinue alcohol drinking is necessary.

Abstract
BACKGROUND In recent years, with the growing availability of image-enhanced gastrointestinal endoscopy, gastroenterologists have contributed to the early detection of pharyngeal squamous cell carcinomas (SCC).
AIM To clarify the clinical characteristics of pharyngeal SCCs detected by gastrointestinal endoscopy.
METHODS This is a retrospective cohort study conducted in a single-center, a university hospital in Japan. We retrospectively assessed the clinical records of 522 consecutive patients with oropharyngeal or hypopharyngeal SCC who were examined in our hospital between 2011 and 2018. The lesions were classified into two groups: Group GE (detected by gastrointestinal endoscopy) and Group non-GE (detected by means other than gastrointestinal endoscopy). The clinical characteristics were compared between the two groups. Continuous data were compared using the Mann–Whitney U test. Pearson’s χ2 test or Fisher's exact test was used to analyze the categorical data and compare proportions. The Kaplan–Meier method was used to estimate the cumulative patient survival rates.
RESULTS In our study group, the median age was 65 years and 474 patients (90.8%) were male. One hundred and ninety-six cases (37.5%) involved the oropharynx and 326 cases (62.5%) involved the hypopharynx. Three hundred and ninety-five cases (75.7%) had some symptoms at the time of diagnosis. One hundred and forty-five (27.8%) cases had concurrent ESCC or a history of ESCC. One hundred and sixty-four (31.4%) cases were detected by gastrointestinal endoscopy and classified as Group GE. The proportions of asymptomatic cases, cTis-1 cases and cases with no lymph node metastasis were significantly higher in Group GE than Group non-GE (61.6% vs 7.3%, P < 0.001, 32.9% vs 12.0%, P < 0.001 and 69.5% vs 19.0%, P < 0.001). Endoscopic laryngo-pharyngeal surgery or endoscopic submucosal dissection were performed in only 0.6% of the lesions in Group non-GE but in 21.3% of the lesions in Group GE (P < 0.001). Overall survival was significantly longer in Group GE than in Group non-GE (P = 0.018). The 2-year and 4-year survival rates were 82.5% and 70.7% in Group GE, and 71.5% and 59.0% in Group non-GE, respectively.
CONCLUSION Gastrointestinal endoscopy plays an important role in the early detection and improving the prognosis of pharyngeal SCCs.

The characteristics and prognostic significance of esophageal squamous cell carcinoma with synchronous multiple lesions: over 10-year experience. Esophagus 2021; 18:851-860. [PMID: 34110538 DOI: 10.1007/s10388-021-00856-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Accepted: 06/01/2021] [Indexed: 02/03/2023]
Abstract
PURPOSE Esophageal squamous cell carcinoma (ESCC) is occasionally observed with synchronous multiple tumor lesions. Our study is aiming to define the clinical and prognostic features of this pathological subtype. METHODS This study included a large cohort of 1126 ESCC patients received esophagectomy with systemic lymph-node dissection between 2003 and 2013 in Sun Yat-sen University Cancer Center. The characteristics and prognostic significance of ESCC with multiple lesions were analyzed. The propensity score matching was performed to balance the baseline clinical characteristics. RESULTS A total of 103 patients (9.1%) with 216 synchronous multiple lesions were identified from postoperative gross samples. Among them, 94 patients had two lesions, and 8 patients had three lesions, while only one patient had four lesions. The consistency of pT stages and histological grade among tumor lesions from the same gross sample were 19.4% (20/103) and 37.9% (39/103), respectively. Additionally, the tumor sites, sizes, and even the pathological subtypes can be variant in one patient. The preoperative upper gastrointestinal endoscopy could only identified 80.1% of the multiple tumor lesions. The male gender (P = 0.012), positive personal cancer history (P < 0.001), and higher pN stages (P < 0.001) were independent risk factors for synchronous multiple lesions. Patients with multiple lesions showed significantly lower survival rate (P = 0.002), and the multiple-lesion was an independently adverse prognostic factor in operable ESCC (P = 0.002). CONCLUSION ESCC with multiple lesions had unique clinical features and should not be simply treated as the one-lesion ESCC. Due to its worse prognostic impact, advanced multidisciplinary therapies should be considered for patients with multiple esophageal tumor lesions.

Abstract
Head and neck cancers, especially in hypopharynx and oropharynx, are often detected at advanced stage with poor prognosis. Narrow band imaging enables detection of superficial cancers and transoral surgery is performed with curative intent. However, pathological evaluation and real‐world safety and clinical outcomes have not been clearly understood. The aim of this nationwide multicenter study was to investigate the safety and efficacy of transoral surgery for superficial head and neck cancer. We collected the patients with superficial head and neck squamous cell carcinoma who were treated by transoral surgery from 27 hospitals in Japan. Central pathology review was undertaken on all of the resected specimens. The primary objective was effectiveness of transoral surgery, and the secondary objective was safety including incidence and severity of adverse events. Among the 568 patients, a total of 662 lesions were primarily treated by 575 sessions of transoral surgery. The median tumor diameter was 12 mm (range 1–75) endoscopically. Among the lesions, 57.4% were diagnosed as squamous cell carcinoma in situ. The median procedure time was 48 minutes (range 2–357). Adverse events occurred in 12.7%. Life‐threatening complications occurred in 0.5%, but there were no treatment‐related deaths. During a median follow‐up period of 46.1 months (range 1–113), the 3‐year overall survival rate, relapse‐free survival rate, cause‐specific survival rate, and larynx‐preservation survival rate were 88.1%, 84.4%, 99.6%, and 87.5%, respectively. Transoral surgery for superficial head and neck cancer offers effective minimally invasive treatment. Clinical trials registry number: UMIN000008276.

Abstract
OBJECTIVES/HYPOTHESIS Transoral surgery (TOS) has become increasingly popular for patients with superficial hypopharyngeal squamous cell carcinoma (SCC). However, the number of patients in whom metachronous multiple SCC of the head and neck (HNSCC) occurs has also increased. In this study, we investigated whether multiple lugol-voiding lesions (LVLs) in the pharyngeal background mucosa observed during TOS would be a biomarker of metachronous HNSCC. STUDY DESIGN Retrospective study. METHODS We examined 362 patients who underwent TOS for superficial hypopharyngeal carcinoma. Endoscopic images were reviewed in a blinded fashion by two endoscopists. LVLs in the pharyngeal mucosa were graded as follows: A, no lesions; B, 1 to 4 lesions; and C, ≥5 lesions per endoscopic view. RESULTS Cumulative incidence curves of secondary HNSCC in the groups of grades A, B, and C revealed 3-year incidence rates of 14.4%, 18.8%, and 29.3%, respectively (P = .001 for A vs. C and P = .002 for B vs. C). Cumulative incidence curves of third HNSCC in the groups of grades A, B. and C revealed 5-year incidence rates of 3.9%, 9.8%, and 19.6%, respectively (P = .001 for A vs. C and P = .006 for B vs. C). Cumulative incidence curves of fourth HNSCC in the groups of grades A, B, and C revealed 7-year incidence rates of 0%, 2.3%, and 13.2%, respectively (P = .025 for A vs. C and P = .009 for B vs. C). CONCLUSIONS Multiple LVLs in the pharyngeal mucosa increase the risk of development of metachronous multiple HNSCC.

Abstract
Urogenital schistosomiasis remains a major global challenge. Optimal management of this infection depends upon imaging-based assessment of sequelae. Although established imaging modalities such as ultrasonography, plain radiography, magnetic resonance imaging (MRI), narrow band imaging, and computerized tomography (CT) have been used to determine tissue involvement by urogenital schistosomiasis, newer refinements in associated technologies may lead to improvements in patient care. Moreover, application of investigational imaging methods such as confocal laser endomicroscopy and two-photon microscopy in animal models of urogenital schistosomiasis are likely to contribute to our understanding of this infection's pathogenesis. This review discusses prior use of imaging in patients with urogenital schistosomiasis and experimentally infected animals, the advantages and limitations of these modalities, the latest radiologic developments relevant to this infection, and a proposed future diagnostic standard of care for management of afflicted patients.

Relationship between the microvascular patterns observed by magnifying endoscopy with narrow-band imaging and the depth of invasion in superficial pharyngeal squamous cell carcinoma. Esophagus 2021; 18:111-117. [PMID: 32514752 DOI: 10.1007/s10388-020-00754-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Accepted: 05/29/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Prediction of the invasive depth is the objective of endoscopic observation for digestive cancer. In superficial esophageal cancer, a close relationship between microvascular patterns observed by magnifying endoscopy with narrow-band imaging (M-NBI) and pathological depth of invasion is well known. The ability of M-NBI to predict the invasion depth in superficial pharyngeal squamous cell carcinoma (SPSCC) has been seldom evaluated. This study aimed to clarify the relationship between the microvasculature patterns and pathological depth in SPSCC. METHODS SPSCC lesions evaluated with M-NBI followed by endoscopic resection were analyzed between April 2010 and March 2017. Endoscopic images were classified as microvasculature tumor types B1, B2, and B3 according to the Japan Esophageal Society classification. The pathological depth of invasion was described as either squamous cell carcinoma in situ (Tis) or invasive subepithelial cancer, and the tumor thickness of all lesions was examined. Data were analyzed using the unpaired t, χ2, or Mann-Whitney U test. RESULTS Type B1 and type B2/B3 (35/3) microvessels were found in 180 lesions (82%) and 39 (18%), respectively. Of the flat lesions, 115 (83%) were classified as Tis and 23 (17%) as subepithelial cancer. Positive and negative predictive values of the B1 vessels were 77% and 82%, respectively. Additional analysis showed that the positive predictive value of the B1 vessels for the flat-type lesions was 87%; the negative predictive value for the elevated lesions was 93%. CONCLUSIONS Microvascular patterns observed by M-NBI are an important factor in predicting the pathological depth of invasion.

Abstract
BACKGROUND Second primary head and neck cancers after endoscopic resection of esophageal squamous cell carcinoma adversely affect patients' outcomes and the quality of life; however, an adequate surveillance schedule remains unclear. METHODS We analyzed 330 patients with early esophageal squamous cell carcinoma who underwent endoscopic resection and were registered in the multicenter cohort study to evaluate adequate surveillance for detection of second primary head and neck cancers. Gastrointestinal endoscopists examined the head and neck regions after 3-6 months of endoscopic resection for esophageal squamous cell carcinoma and subsequently every 6 months. An otolaryngologist also examined the head and neck regions at the time of endoscopic resection for esophageal squamous cell carcinoma and at 12 months intervals thereafter. RESULTS During the median follow-up period of 49.4 months (1.3-81.2 months), 33 second primary head and neck cancers were newly detected in 20 patients (6%). The tumor site was as follows: 22 lesions in the hypopharynx, eight lesions in the oropharynx, two lesions in larynx and one lesion in the oral cavity. The 2-year cumulative incidence rate of second primary head and neck cancers was 3.7%. Among them, 17 patients with 29 lesions were treated by transoral surgery. One patient with two synchronous lesions was treated by radiotherapy. Two lesions in two patients were not detected after biopsy. All patients were cured with preserved laryngeal function. CONCLUSIONS Surveillance by gastrointestinal endoscopy every 6 months and surveillance by an otolaryngologist every 12 months could detect second primary head and neck cancers at an early stage, thereby facilitating minimally invasive treatment.

Abstract
Volatile organic compound (VOC) breath testing of lung and head and neck squamous cell carcinoma (SCC) has been widely studied, however little is known regarding VOC profiles of in-situ SCC. A prospective study of VOC in patients with histologically proven SCC, either in-situ or advanced, and controls. Breath samples were analysed using the E-nose Cyranose ®320 and by gas chromatography/mass spectroscopy. Predictive models were developed using bootstrap forest using all 32 sensors. Data from 55 participants was analysed: 42 SCC cases comprising 20 bronchial (10 in-situ, 10 advanced) and 22 laryngeal (12 in-situ, 10 advanced), and 13 controls. There were 32 (76%) male SCC cases with mean age 63.6 (SD = 9.5) compared with 11 (85%) male controls with mean age 61.9 (SD = 10.1). Predictive models for in situ cases had good sensitivity and specificity compared to controls (overall, 95% and 69%; laryngeal, 100% and 85%; bronchial, 77% and 80%). When distinguishing in-situ and advanced tumours, sensitivity and specificity 82% and 75% respectively. For different tumour types (bronchial versus advanced laryngeal) sensitivity and specificity were 100% and 80% respectively. VOCs isolated from in-situ cancers included some previously demonstrated in advanced cancers and some novel VOCs. In-situ bronchial and laryngeal cancer can be detected by VOC analysis. Distinction from normal controls and between the two tumour types could allow screening in high risk groups for these curable lesions.

Abstract
Background and study aims Patients with esophageal squamous cell carcinoma (SCC) are at high risk of developing second primary SCCs in the hypopharynx. However, such second primary tumors are difficult to observe because of lumen closure. The Valsalva maneuver using a dedicated mouthpiece is a promising technique to visualize the hypopharynx during transoral endoscopy. In the current study, we investigated the utility of this method. Patients and methods The current study was a randomized, controlled, crossover trial. Patients with esophageal SCC were randomly assigned first to undergo pharyngeal observation using the dedicated mouthpiece followed by observation using a conventional mouthpiece, or vice versa. The primary endpoint was complete visualization of the hypopharynx, which was assessed blindly by three external evaluators. Results A total of 68 pharyngeal examinations were analyzed - 34 with the dedicated mouthpiece and 34 with a conventional mouthpiece. Complete visualization was achieved in 68 % of the examinations (23/34) using the dedicated mouthpiece, whereas none of the examinations using the conventional mouthpiece achieved complete visualization of the hypopharynx. Observation scores of the oropharynx were not significantly different between both types of examination ( P = 0.50). No serious adverse events (AEs) occurred. Conclusions Endoscopic view of the hypopharynx was markedly improved by the Valsalva maneuver using the dedicated mouthpiece, with no serious AEs. This procedure should be included in the endoscopic examinations for the patients with esophageal SCCs.

Abstract
OBJECTIVE To evaluate the usefulness of a training program on endoscopic head and neck surveillance for beginner endoscopists. METHODS This prospective multicenter study included 13 beginner endoscopists from 10 institutions who received training in systematic observation techniques and diagnostic criteria, and the training involved hands-on learning. Between May 2016 and February 2017, enrolled patients with current or previously diagnosed esophageal squamous cell carcinomas underwent head and neck surveillance using narrow band imaging (NBI) endoscopy, and histologically confirmed head and neck squamous cell carcinoma (HNSCC) detection rates, endoscopic image quality, and examination times were compared before (group A) and after (group B) the training program. Maximum possible score for the endoscopic images was 30 points. RESULTS A total of 330 patients, comprising 181 in group A and 149 in group B, were enrolled. Three patients with HNSCC were detected in group A (1.7%) and in group B (2.0%; P = 1.000). Mean ± standard deviation (SD) examination times were 157 ± 71 s and 174 ± 109 s in groups A and B, respectively, (P = 0.073). Mean ± SD scores of the endoscopic images were 25.04 ± 5.47 points and 27.01 ± 4.35 points in groups A and B, respectively, (P < 0.001). CONCLUSION The HNSCC detection rate based on the use of NBI on patients with ESCC did not improve after the training program for beginner endoscopists; however, endoscopic image quality improved significantly after the training program.

Abstract
BACKGROUND AND AIM Simultaneous and metachronous head and neck cancers are likely to develop in patients with current or previous esophageal cancer. The Valsalva maneuver facilitates the visualization of the hypopharyngeal area during endoscopic observation, but it requires transnasal endoscopy. We developed a novel Valsalva maneuver using transoral endoscopy with a lip cover-type mouthpiece. METHODS Between March 2018 and July 2018, 107 patients with current or previous esophageal cancer who were scheduled to undergo upper gastrointestinal endoscopy were included in our pilot study. We performed the Valsalva maneuver using our newly developed mouthpiece and transoral endoscopy in the patients and evaluated the hypopharyngeal region, including the postcricoid area and the posterior wall of the hypopharynx. The outcome measure was procedural success rate, which was graded as "complete," "incomplete," and "none." RESULTS Observation of the hypopharyngeal area was "complete" in 81 patients (76%) using the Valsalva maneuver. However, in 25 patients and in 1 patient, observation was "incomplete" and "none," respectively. Seven lesions were newly detected in seven patients during the study period. CONCLUSIONS The Valsalva maneuver using transoral endoscopy with a lip cover-type mouthpiece is feasible for the visualization of the postcricoid area and the posterior wall of the hypopharynx. Particularly, this technique would contribute to early detection of head and neck cancers.

Abstract
PURPOSE The aim was to investigate the current status of esophageal endoscopy, including the evaluation of smoking and alcohol consumption, in Japan. METHODS A total of 47,441 patients who underwent 69,748 sessions of esophageal endoscopy were registered in the Japan Endoscopy Database between January 2015 and March 2017. The study variables were as follows: (1) methods for monitoring the esophagus and the time required for monitoring and (2) the status of smoking and alcohol consumption in patients with esophageal cancer and head and neck cancer. RESULTS Image-enhanced endoscopy was performed in 10.6%, Lugol chromoendoscopy in 4.1%, and magnifying endoscopy in 3.2%. The mean time required for gastrointestinal endoscopy was 10 min 58 s. The mean examination times in patients with or without monitoring of the head and neck were 10 min 51 s and 11 min 13 s, respectively. In 57.0% of the patients with esophageal cancer, the head and neck were monitored at the time of gastrointestinal endoscopy. The proportion of current smokers (esophageal cancer: 16.8-4.7%; head and neck cancer: 24.3-9.3%) and addicted drinkers (esophageal cancer: 52.3-40.8%; head and neck cancer: 50.2-47.3%) were lower at the second or subsequent endoscopy than at the initial endoscopy. CONCLUSIONS The new strategy for esophageal endoscopy has led to an evolutionary change in Japan. The patients with esophageal cancer and head and neck cancer who underwent a second or subsequent endoscopy had lower incidences of smoking and alcohol consumption, although the incidences remained high.

Abstract
BACKGROUND We evaluated the accuracy of endoscopic findings observed by narrow band imaging (NBI) combined with magnifying gastrointestinal endoscopy (GIE) for the differential diagnosis of cancerous and noncancerous laryngeal lesions. METHODS A total of 166 vocal cord lesions for which good images were obtained on NBI with magnifying GIE were evaluated with respect to the following 6 variables: macroscopic type, tumor location, color, white coat, keratinization, and abnormal microvessels. RESULTS Multivariate analysis showed that white coat (odds ratio [OR], 2.95, P = 0.05), keratosis (OR, 3.14, P = 0.02) and abnormal microvessels (OR, 31.1, P < 0.0001) were significantly related to laryngeal cancer. In the diagnosis of laryngeal cancer, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of abnormal microvessels were 84.4%, 88.6%, 91%, 80.5%, and 86.1%, respectively. CONCLUSION The abnormal microvessels on NBI combined with magnifying GIE are useful for the differential diagnosis of laryngeal lesions.

Risk assessment of metachronous squamous cell carcinoma after endoscopic resection for esophageal carcinoma based on the genetic polymorphisms of alcoholdehydrogense-1B aldehyde dehydrogenase-2: temperance reduces the risk. J Gastroenterol 2018; 53:1120-1130. [PMID: 29423536 DOI: 10.1007/s00535-018-1441-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Accepted: 01/31/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND Metachronous multiple squamous cell carcinoma (SCC) of the esophagus and the head and neck is commonly observed in patients who have previously undergone endoscopic resection (ER) for SCC of the esophagus (ESCC). We evaluated the risk for developing metachronous SCC following ER for ESCC based on the genetic polymorphisms for alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) as well as the alcohol consumption and smoking habits. METHODS We studied 158 patients who underwent ER for ESCC (median follow-up 80 months). Genotyping of ADH1B/ALDH2 was performed using saliva sampling. The alcohol consumption and smoking histories of the patients before and after the ER were documented. RESULTS Multivariate analyses revealed that inactive heterozygous ALDH2 [hazard ratio (HR) 2.25] and alcohol consumption after ER (HR 1.94) were independently associated with the risk of developing secondary SCC. Moreover, inactive heterozygous ALDH2 (HR 4.39) and alcohol consumption after the ER (HR 2.82) were independently associated with the risk of a third SCC. We analyzed 110 patients who had a history of moderate or heavy alcohol consumption before the ER. The 3-year cumulative incidence rates of secondary SCC in the temperance (n = 65) and non-temperance groups (n = 45) were 14.0 and 42.1% (p = 0.0002). Further, the 5-year cumulative incidence rates of a third SCC in the temperance and non-temperance groups were 0 and 15.6% (p = 0.0011), respectively. In addition, the 7-year cumulative incidence rates of a fourth SCC in the temperance and non-temperance groups were 0 and 15.3% (p = 0.0015), respectively. CONCLUSIONS Continued alcohol consumption is an important risk factor for the onset of metachronous SCC and is a risk factor for the third and subsequent SCCs. Strict advice in favor of temperance is crucial.

Abstract
PURPOSE Overall local recurrence of oral squamous cell carcinoma (OSCC) is estimated at 20%. Incomplete primary tumour excision contributes to localised postsurgical recurrence of OSCC. The purpose of this study was to report on patient outcomes following resection of OSCC using Narrow Band Imaging (NBI). MATERIALS AND METHODS Patients with OSCC requiring resection were visualised under conventional white light (WL) then NBI using an Olympus NBI ENF-VQ nasendoscope with CLV-180 light source and processor (Olympus Medical Systems, Tokyo, Japan). OSCC tissue was resected to the NBI-defined surgical margins, and patients followed for a minimum of 5 years postsurgery to assess local recurrence rate (LRR) and disease-free survival (DFS). RESULTS Of the 20 patients recruited for this study, one patient (5%) declined follow-up. At the latest follow-up period (up to 7 years postsurgery), 14 of 19 patients (73.68%) were alive with no recurrence. Two patients (10.53%) had died from metastatic disease with no local recurrence, one patient (5.26%) had died from disease with local recurrence, and two patients (10.53%) had died disease-free from other causes. In total, 16 of 19 patients (84.21%) who were followed for a minimum of 5 years were still alive and had not developed local recurrence. Only one patient developed local recurrence. Five-year DFS was 84.21% and LRR was 5.26%. CONCLUSION Resection to NBI-defined margins improves survival rates and decreases recurrence rates of OSCC compared to traditional methods and should be adopted as the new gold standard for determining mucosal surgical margins for treatment of oral cavity cancer. These promising results have set the scene for a multicentred randomised controlled trial comparing NBI to WL currently underway.

Abstract
OBJECTIVE Curative synchronous double primary cancers of the head and neck and the esophagus (CSC-HE) are frequently detected, but a standard treatment remains to be established. We studied the clinical course to explore appropriate treatment strategies. METHODS We retrospectively studied consecutive 33 patients who had CSC-HE. The disease stage was classified into 4 groups: group A, early head and neck cancer (HNC) and early esophageal cancer (EC); group B, early HNC and advanced EC; group C, advanced HNC and early EC; and group D, advanced HNC and advanced EC. As induction chemotherapy, the patients received 3 courses of TPF therapy (docetaxel 75mg/m2 on day 1, cisplatin 75mg/m2 on day 1, and 5-fluorouracil 750mg/m2 on days 1-5) at 3-week intervals. The clinical courses and treatment outcomes were studied according to the disease stage of CSC-HE. RESULTS The disease stage of CSC-HE was group A in 1 patient (3%), group B in 9 patients (27.3%), group C in 3 patients (9.1%), and group D in 20 patients (60.6%). The median follow-up was 26months, and the 2-year overall survival rate was 67.4%. In groups A, B, and C, the 2-year overall survival rate was 83.3%. In group D, the 2-year overall survival rate was 62.6%. Ten of 20 patients in group D received induction chemotherapy with TPF, and 6 patients were alive and disease free at the time of this writing. CONCLUSION The treatment outcomes of patients with CSC-HE were relatively good. TPF induction chemotherapy might be an effective treatment for patients with advanced HNC and advanced EC.

Abstract
BACKGROUND A fluorescent probe glutamylprolyl hydroxymethyl rhodamine green (EP-HMRG), which becomes fluorescent after cleavage by dipeptidyl peptidase-IV (DPP-IV), has been reported to be useful for the detection of esophageal cancer. Thus, we investigated whether head and neck squamous cell carcinoma (HNSCC) can be detected by spraying EP-HMRG. METHODS Fluorescence imaging of 17 cases of HNSCCs resected using endoscopic or surgical resection was performed ex vivo after spraying EP-HMRG, and then the fluorescence intensity of the tumors and normal mucosa were measured. RESULTS Iodine-voiding lesions became fluorescent within a few minutes after the application of EP-HMRG in 12 resected tumors without a history of radiotherapy but this was not observed in the normal mucosa. Fluorescence intensity in tumor lesions was significantly higher than normal lesions. However, 5 other tumors that developed after radiotherapy did not have sufficient contrast against normal mucosa. CONCLUSION Fluorescence imaging with EP-HMRG would be useful for rapid detection of superficial HNSCC without a history of radiotherapy.

Abstract
BACKGROUND Alcohol consumption combined with inactive aldehyde dehydrogenase-2 (ALDH2) and the presence of multiple esophageal Lugol-voiding lesions (LVLs; dysplasia) are strong predictors for multiple development of esophageal squamous cell carcinoma (ESCC) in East Asians. We invented a health risk appraisal (HRA) model for predicting the risk of ESCC based on drinking, smoking, dietary habits, and alcohol flushing, i.e., past or present facial flushing after drinking a glass of beer, a surrogate marker for inactive ALDH2. METHODS Prospective follow-up examinations (median follow-up time, 50.3 months) were performed in 278 Japanese men after endoscopic mucosectomy for early ESCC (UMIN Clinical Trials Registry ID: UMIN000001676). RESULTS Sixty-four subjects developed metachronous ESCC. A receiver operating characteristic curve showed that HRA scores ≥12 best predicted the development of metachronous ESCC. The ESCC detection rate per 100 person-years was 9.8 in the high-HRA-score group (n = 104) and 4.5 in the low-HRA-score group (n = 174), and the risk of development of metachronous ESCC was higher in the high-HRA-score group than in the low-HRA-score group (adjusted hazard ratio: 2.00 [95% CI: 1.12-3.30]). Multiple LVLs was a very strong predictor of the development of metachronous SCC, but high HRA scores predicted it independently. The cumulative incidences of metachronous ESCC decreased after drinking cessation in the high-HRA-score drinker group (adjusted hazard ratio: 0.37 [0.14-0.97]). CONCLUSIONS Both the HRA model that included alcohol flushing and the multiple LVL grade predicted the development of metachronous ESCC in Japanese men after endoscopic mucosectomy for ESCC. Drinking cessation in the high-HRA-score drinker group reduced the rate of metachronous ESCC.

Morimoto H, Yano T, Yoda Y, Oono Y, Ikematsu H, Hayashi R, Ohtsu A, Kaneko K. Clinical impact of surveillance for head and neck cancer in patients with esophageal squamous cell carcinoma. World J Gastroenterol 2017; 23:1051-1058. [PMID: 28246479 PMCID: PMC5311094 DOI: 10.3748/wjg.v23.i6.1051] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2016] [Revised: 11/24/2016] [Accepted: 01/18/2017] [Indexed: 02/06/2023] Open
Abstract
AIM
To evaluate the clinical impact of surveillance for head and neck (HN) region with narrow band imaging (NBI) in patients with esophageal squamous cell carcinoma (ESCC).
METHODS
Since 2006, we introduced the surveillance for HN region using NBI for all patients with ESCC before treatment, and each follow-up. The patients with newly diagnosed stage I to III ESCC were enrolled and classified into two groups as follows: Group A (no surveillance for HN region); between 1992 and 2000), and Group B (surveillance for HN region with NBI; between 2006 and 2008). We comparatively evaluated the detection rate of superficial head and neck squamous cell carcinoma (HNSCC), and the serious events due to metachronous advanced HNSCC during the follow-up.
RESULTS
A total 561 patients (group A: 254, group B: 307) were enrolled. Synchronous superficial HNSCC was detected in 1 patient (0.3%) in group A, and in 12 (3.9%) in group B (P = 0.008). During the follow up period, metachronous HNSCC were detected in 10 patients (3.9%) in group A and in 30 patients (9.8%) in group B (P = 0.008). All metachronous lesions in group B were early stage, and 26 patients underwent local resection, however, 6 of 10 patients (60%) in group A lost their laryngeal function and died with metachronous HNSCC.
CONCLUSION
Surveillance for the HN region by using NBI endoscopy increase the detection rate of early HNSCC in patients with ESCC, and led to decrease serious events related to advanced metachronous HNSCC.

Abstract
BACKGROUND AND AIM Standard surveillance methods for pharyngeal cancer have not been established. We conducted a randomized controlled trial to investigate the best sedation method for pharyngeal observation using transoral endoscopy. METHODS In total, 120 patients who underwent surveillance or diagnostic examinations for esophageal cancer were enrolled and divided equally into three groups (no sedation, midazolam, or pethidine hydrochloride). In the midazolam group, midazolam was given i.v. maintaining a Ramsay score of 3. In the pethidine group, pethidine hydrochloride (35 mg) given i.v. Seven sites in five pharyngeal regions were observed on insertion of the endoscope, and graded (0 = poor, 1 = good). After examination, the five pharyngeal regions were scored using a seven-point scale. Primary endpoint was the total score from the five pharyngeal regions. Secondary endpoints were the proportion of the perfect score using the seven-point scale, discomfort score, and adverse events. RESULTS Mean total scores for the no sedation group, the midazolam group and the pethidine group were 5.7, 5.5, and 6.8, respectively (P < 0.0001). Proportion of patients with a perfect score for the no sedation group, the midazolam group and the pethidine group were 53%, 35%, and 89%, respectively (P < 0.0001). The pethidine group had better results than the other two groups. Discomfort score and adverse events were low in the pethidine group. CONCLUSION Pethidine hydrochloride is a feasible and safe sedation method, and was superior to no sedation and midazolam regarding pharyngeal observation of esophageal cancer patients.

Alcohol Consumption and Multiple Dysplastic Lesions Increase Risk of Squamous Cell Carcinoma in the Esophagus, Head, and Neck. Gastroenterology 2016; 151:860-869.e7. [PMID: 27492616 DOI: 10.1053/j.gastro.2016.07.040] [Citation(s) in RCA: 121] [Impact Index Per Article: 15.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2015] [Revised: 07/12/2016] [Accepted: 07/18/2016] [Indexed: 12/02/2022]
Abstract
BACKGROUND & AIMS Some patients develop multiple squamous cell carcinomas (SCCs) in the upper aerodigestive tract, attributed to field cancerization; alcohol consumption has been associated with this process. We examined the association between multiple areas of dysplastic squamous epithelium with the development of SCC of the esophagus or head and neck cancer, as well as alcohol consumption and smoking. METHODS We examined 331 patients with early stage esophageal SCC using Lugol chromoendoscopy to evaluate the dysplastic squamous epithelium in the esophagus. Patients then were assigned to 3 groups, based on the number of Lugol-voiding lesions: A, no lesion; B, 1-9 lesions; or C, 10 or more lesions. Participants completed lifestyle surveys on their history of drinking, smoking, and diet. All participants were evaluated by laryngopharyngoscopy before registration; only those without head and neck cancer were included, except for patients with superficial SCC limited to the subepithelial layer. Lesions detected in the esophagus and head and neck by surveillance were considered to be metachronous. The study end point was the cumulative incidence of metachronous SCCs in the esophagus and head and neck after endoscopic resection of esophageal SCC, according to the grade of Lugol-voiding lesions. At study entry, all patients were instructed to abstain from alcohol and smoking. RESULTS Over the 2-year study period, metachronous SCCs of the esophagus were detected in 4% of patients in group A, in 9.4% of patients in group B, and in 24.7% of patients in group C (P < .0001 for patients in group A vs B or B vs C). Head and neck SCCs were detected in none of the patients in group A, in 1.7% of the patients in group B, and in 8.6% of the patients in group C (P = .016 for patients in group A vs C and P = .008 for patients in group B vs C). SCC of the esophagus or head and neck developed in 4.0% of patients in group A, in 10.0% of patients in group B, and in 31.4% of patients in group C (P < .0001 for group A vs B or A vs C). Alcohol abstinence decreased the risk of multiple SCCs of the esophagus (adjusted hazard ratio, 0.47, 95% confidence interval, 0.25-0.91; P = .025), whereas smoking abstinence did not. CONCLUSIONS Multiple dysplastic lesions in the esophagus increase the risk of multiple SCCs. Alcohol abstinence reduces the risk of metachronous SCCs.

Abstract
Background The incidence rate has been increasing for superficial head and neck squamous cell carcinoma (HNSCC) discovered through surveillance endoscopic study using narrow band imaging (NBI), a procedure mainly used for high-risk patients with esophageal squamous cell carcinoma (ESCC). However, there are few reports on the natural history of superficial HNSCC. The aim of this retrospective study was to investigate the natural history of superficial HNSCC. Methods From January 2007 to December 2012, 535 consecutive histologically confirmed superficial HNSCCs at the oropharynx, hypopharynx, or larynx in 319 patients were detected by endoscopic surveillance examination by using NBI. Of those, 20 untreated and observed lesions fulfilled the eligibility criteria and were analyzed in this study. Results Twenty lesions from 17 patients were analyzed. All patients were men ranging from 52 to 86 years of age, with a median age of 69 years. The median endoscopic follow-up period was 20 months (range, 6–71); 17 lesions progressed in size. In this study, four patients died; the causes of death were synchronous ESCC, synchronous HNSCC, acute myocardial infarction, and unknown causes. No patient died from progression of superficial HNSCC. Conclusions Most superficial HNSCC has the potential to change progressively. Therefore, superficial HNSCC should be detected at an early stage and be treated less invasively, such as with endoscopic resection or partial resection.

Abstract
BACKGROUND AND STUDY AIMS Magnifying narrow-band imaging (NBI) endoscopy enables the diagnosis of minute esophageal neoplasia. We aimed to evaluate clinicopathological diagnosis of minute esophageal neoplasia by using magnifying NBI endoscopy and biopsy. PATIENTS AND METHODS In total, 309 patients (127 men and 182 women) with minute esophageal lesions of intrapapillary capillary loop (IPCL) type IV were enrolled. Of these patients, 249 underwent biopsy for histologic diagnosis and also for treatment. Of the 249 patients, 123 underwent follow-up with endoscopy. We analyzed the clinicopathologic characteristics and prognosis of these lesions after biopsy. RESULTS Of the 249 biopsied lesions, we histologically diagnosed 11 as high-grade intraepithelial neoplasia (HGIN), 41 as low-grade intraepithelial neoplasia (LGIN), and 197 as non-neoplasia (Non-N) including inflammation. Six of the 11 HGINs and 11 of the 41 LGINs showed slight elevation. Background coloration was observed in 9 of 11 HGINs, 34 of 41 LGINs, and 33 of 197 Non-Ns. Of the 249 biopsied lesions, 147 were microscopically measurable. The average diameter was 1.4 mm for HGINs and 0.8 mm for LGINs. Of the 123 patients who underwent post-biopsy follow-up, 93 (76 %) showed no lesions at the biopsied sites during the NBI examinations and were suspected to have undergone complete resection by biopsy. CONCLUSIONS Biopsy was useful for diagnosis and treatment of minute esophageal lesions, diagnosed as IPCL type IV by magnifying NBI endoscopy.

Abstract
OBJECTIVES The oral carcinoma is a widespread pathology and still presents poor prognosis. Among the available procedures for its early detection, Narrow Band Imaging technique allows to assess potential vascular network abnormalities. The reliability of this technique in the detection of dysplastic and neoplastic oral lesions was evaluated in a preclinical and clinical study. MATERIALS AND METHODS In the preclinical study, a chemical oral carcinogen was administered to 50 mice to induct both dysplastic and neoplastic oral lesions. In the clinical study 91 patients, bearing suspicious premalignant and malignant oral lesions, have been included. Images of animals' and patients' lesions were acquired under white and Narrow Band Imaging light prior to biopsy. Two expert raters examined the images and classified lesions, which were eventually compared to the histological diagnosis. The diagnostic performance included sensitivity, specificity, positive likelihood ratio, positive and negative predictive values, accuracy, percentages and degree of agreement between raters' evaluation and the histological report. RESULTS In the preclinical study sensitivity ranged from 0.57 to 1, specificity from 0.85 to 0.99, positive likelihood ratio from 6.54 to 65.04, positive predictive values from 0.32 to 0.96, negative predictive values from 0.91 to 1 and accuracy from 0.86 to 0.98. In the clinical study sensitivity ranged from 0.63 to 0.99, specificity from 0.89 to 1, positive likelihood ratio from 8.45 to 61.47, positive predictive values from 0.59 to 0.96, negative predictive values from 0.78 to 1 and accuracy from 0.82 to 0.99. CONCLUSION Narrow Band Imaging is an accurate technique, which holds a great potential for tumour angiogenesis evaluation and for the subsequent early detection of suspicious premalignant and malignant oral lesions.

Abstract
Background Detecting superficial head and neck squamous cell carcinoma (HNSCC) by endoscopy is challenging because of limited morphological hallmarks, and iodine cannot be applied to head and neck lesions due to severe mucosal irritation. γ-glutamyltranspeptidase (GGT), a cell surface enzyme, is overexpressed in several cancers, and it has been reported that γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG), a fluorescent targeting agent which can be enzymatically activated and becomes fluorescent after cleavage of a GGT-specific sequence, can be activated within a few minutes after application to animal models. We investigated whether early HNSCC can be detected by applying gGlu-HMRG to clinical samples. Methods gGlu-HMRG was applied to four HNSCC cell lines, and fluorescence was observed by fluorescence microscopy and flow cytometry. Immunohistological examination was performed in three recent cases of endoscopic submucosal dissection (ESD) to investigate GGT expression. Fluorescence imaging with gGlu-HMRG in eight clinical samples resected by ESD or surgery was performed, and fluorescence intensity of tumor and normal mucosa regions of interest (ROI) was prospectively measured. Results All four gGlu-HMRG-applied cell lines emitted green fluorescence. Immunohistological examination demonstrated that GGT was highly expressed in HNSCC of the recent three ESD cases but barely in the normal mucosa. Fluorescence imaging showed that iodine-voiding lesions became fluorescent within a few minutes after application of gGlu-HMRG in all eight resected tumors. Tumor ROI fluorescence intensity was significantly higher than in the normal mucosa five minutes after gGlu-HMRG application. Conclusions Fluorescence imaging with gGlu-HMRG would be useful for early detection of HNSCC.

Endoscopic surveillance of head and neck cancer in patients with esophageal squamous cell carcinoma. Endosc Int Open 2016; 4:E752-5. [PMID: 27556090 PMCID: PMC4993894 DOI: 10.1055/s-0042-106720] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2016] [Accepted: 04/11/2016] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND AND STUDY AIMS Multiple squamous cell carcinomas (SCCs) frequently arise in the upper aerodigestive tract, referred to as the field cancerization phenomenon. The aim of this study was to elucidate the detailed clinical features of second primary head and neck (H&N) SCCs arising in patients with esophageal SCC. PATIENTS AND METHODS A total of 818 patients underwent endoscopic resection for superficial esophageal cancer between January 2006 and December 2013. Of these, 439 patients met our inclusion criteria, and we retrospectively investigated the incidence, primary sites, and stages of second primary H&N SCCs in these patients. RESULTS A total of 53 metachronous H&N SCCs developed in 40 patients after a median follow-up period of 46 months (range 9 - 109). The cumulative incidence rates of metachronous H&N SCCs at 3, 5, and 7 years were 5.3 %, 9.7 %, and 17.2 %, respectively. These lesions were frequently located at pyriform sinus or in the posterior wall of the pharynx (70 %, 37/53 lesions). Most of the lesions were detected at an early stage, though 4 lesions were associated with lymph node metastasis when their primary sites were detected (1 postcricoid area, 2 posterior wall of hypopharynx, and 1 lateral wall of oropharynx). CONCLUSIONS Patients with esophageal SCC should undergo careful inspection of the pyriform sinus and posterior wall of the pharynx for detection of H&N SCCs. Methods to open the hypopharyngeal space, such as the Valsalva maneuver, should be included in the surveillance program.

Abstract
OBJECTIVE To estimate the clinical significance of target biopsy for clinical diagnosis and determine accurate laryngeal lesion pathologic specimen acquisition via narrow-band imaging (NBI) endoscopy. METHODS A total of 138 samples from patients with laryngeal lesions (carcinoma, 118; hyperplasia, 3; mild dysplasia, 2; moderate dysplasia, 5; severe dysplasia, 5; vocal cord polyp, 1; and inflammatory lesion, 4) were collected from the Department of Otolaryngology Head and Neck Surgery of Tianjin Union Medical Center from 1 January 2013 to 1 February 2015. All patients were divided into the regular biopsy and NBI target biopsy groups; the imaging data were recorded and patient samples were biopsied. Pathologic diagnoses were used to evaluate the accuracies of regular and target biopsy. RESULTS Based on the pathologic diagnosis, NBI target pathology yielded an accurate laryngeal lesion pathologic specimen acquisition rate of 95.6% (65/68), significantly higher than that yielded by regular biopsy (75.7%, 53/70; χ2 = 10.99, P = 0.001). In the NBI target pathology group, the correct accurate pathologic specimen acquisition rates at laryngeal cancer diagnostic stages 0 (Tis), I and II were 100%, 100% and 85.71%, respectively, which were higher than the corresponding rates in the regular biopsy group (0%, χ2 = 10.000, P = 0.002; 25%, χ2 = 5.625, P = 0.018; and 38.46%, χ2 = 6.454, P = 0.011, respectively). CONCLUSIONS In cases of laryngeal carcinoma, NBI endoscopy plays an important role in clinical diagnosis and accurate pathologic specimen acquisition and could be a regular clinical method for laryngeal lesion detection.

Abstract
Narrow Band Imaging (NBI) is an endoscopic optical imaging enhancement technology that improves the contrast of mucosal surface texture, and enhances visualisation of mucosal and submucosal vasculature. White light is filtered to emit two 30-nm narrow bands of blue (415 nm) and green light (540 nm) light simultaneously, the former corresponding to the main peak absorption spectrum of haemoglobin, and the latter allowing visualisation of blood vessels in the deeper mucosal and submucosal layers. NBI has been used to better assess oral potentially malignant disorders (OPMD), identify oral and oropharyngeal squamous cell carcinoma (SCC), and to define surgical margins of head and neck malignancies. NBI shows great potential in improving detection rates of OPMD, facilitating better assessment of oral and oropharyngeal SCC, and reducing the risk of recurrence for oral SCC. Although further research is required to better understand and define intrapapillary capillary loop (IPCL) patterns and to relate these with clinical, histopathological and molecular parameters especially for early mucosal changes, there is building evidence to recommend its use as the new gold standard for endoscopic assessment in head and neck oncology.

Abstract
BACKGROUND AND AIMS Although endoscopic submucosal dissection (ESD) has been applied for superficial pharyngeal cancer, no prospective trials have been reported. To investigate the efficacy and safety of ESD for superficial pharyngeal cancer, we conducted a prospective phase II trial. METHODS Fifty-four patients with 73 lesions were enrolled from September 2010 to August 2014, and ESD was performed. The primary endpoint was the complete resection rate. Secondary endpoints were safety, recurrence-free survival, overall survival, and incidence of metachronous pharyngeal cancer. RESULTS Fifty-four patients had stage 0-III cancer: stage 0, n = 22; stage I, n = 14; stage II, n = 17; and stage III, n = 1. The en bloc resection rate was 100%, and the complete resection rate was 79.5% (58/73 lesions; 95% confidence interval, 68%-88%). No serious adverse events related to ESD were encountered. Four patients required nasogastric intubation and feeding. No patients required percutaneous endoscopic gastrostomy and tracheotomy. Swallowing, speech, and airway functions were preserved in all patients. One of the 54 patients died of an unrelated illness. Median follow-up was 27 months (range 6-55 months). Local cervical lymph node metastasis was observed in 1 patient, and the case was salvaged successfully with lymph node dissection. The 3-year overall and recurrence-free survival rates were 97.7% and 98.1%, respectively. Cumulative development of multiple cancers of the pharynx at 3 years was 18.4%. CONCLUSIONS ESD appears to be a safe and effective minimally invasive treatment in patients with superficial pharyngeal cancer. ( CLINICAL TRIAL REGISTRATION NUMBER UMIN000003623.).

Abstract
BACKGROUND AND AIM Narrow-band imaging (NBI) is widely available and over the last decade has been applied as a detection and characterization technique for superficial neoplasms of the aerodigestive tract. The aims of the present study were to systematically review clinical trials of NBI endoscopy and to investigate an upgraded NBI system using a novel endoscope for superficial squamous neoplasms in the orohypopharynx and esophagus. METHODS Studies on the diagnostic use of NBI endoscopy for superficial squamous neoplasms in the orohypopharynx and esophagus were retrieved from MEDLINE and PubMed and reviewed. An upgraded NBI system using a novel endoscope was investigated with our clinical cases. RESULTS In many clinical trials, NBI endoscopy with or without magnification had high diagnostic value for superficial squamousneoplasms in the orohypopharynx and esophagus. An upgraded NBI system can produce a significantly brighter endoscopic view than conventional endoscopes with high-quality magnified images that could be used to diagnose superficial squamous neoplasms. CONCLUSIONS NBI endoscopy with or without magnification has diagnostic utility for superficial squamous neoplasms in the orohypopharynx and esophagus. The upgraded NBI endoscopic system is expected to facilitate the use of NBI and magnifying endoscopic diagnosis.

Abstract
Esophageal cancer is frequently associated with squamous cell carcinoma in the head and neck. Both cigarette smoking and alcohol consumption are risk factors for multiple cancers of the head and neck, as well as the esophagus. Routine screening and close follow-up for second cancers are important in patients with esophageal cancer or head and neck cancer. For this purpose, endoscopy with Lugol's staining, as well as narrow-band imaging combined with magnifying endoscopy, is a powerful tool for the early detection of esophageal cancer. Multimodal therapy is essential for patients with double cancers. When considering surgical treatment, the curability of both cancers must be carefully evaluated. If both tumors are potentially curable, each lesion should be treated individually. In patients with metachronous double cancers, the prior treatment of the first primary carcinoma often affects the treatment of the second cancer. Close cooperation among medical staff members is essential for complicated surgeries for double cancers. Techniques that are appropriate for each case must be adopted, such as careful dissection, staged operations, muscular flaps and microvascular anastomosis.
