Furumoto H, Kato T, Wakiyama H, Furusawa A, Choyke PL, Kobayashi H. Endoscopic Applications of Near-Infrared Photoimmunotherapy (NIR-PIT) in Cancers of the Digestive and Respiratory Tracts. Biomedicines 2022; 10:biomedicines10040846. [PMID: 35453596 PMCID: PMC9027987 DOI: 10.3390/biomedicines10040846] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 03/24/2022] [Accepted: 03/25/2022] [Indexed: 12/11/2022] Open
Abstract
Near-infrared photoimmunotherapy (NIR-PIT) is a newly developed and promising therapy that specifically destroys target cells by irradiating antibody-photo-absorber conjugates (APCs) with NIR light. APCs bind to target molecules on the cell surface, and when exposed to NIR light, cause disruption of the cell membrane due to the ligand release reaction and dye aggregation. This leads to rapid cell swelling, blebbing, and rupture, which leads to immunogenic cell death (ICD). ICD activates host antitumor immunity, which assists in killing still viable cancer cells in the treated lesion but is also capable of producing responses in untreated lesions. In September 2020, an APC and laser system were conditionally approved for clinical use in unresectable advanced head and neck cancer in Japan, and are now routine in appropriate patients. However, most tumors have been relatively accessible in the oral cavity or neck. Endoscopes offer the opportunity to deliver light deeper within hollow organs of the body. In recent years, the application of endoscopic therapy as an alternative to surgery for the treatment of cancer has expanded, providing significant benefits to inoperable patients. In this review, we will discuss the potential applications of endoscopic NIR-PIT, especially in thoracic and gastrointestinal cancers.

Tan S, Chen Y, Dai L, Zhong C, Chai N, Luo X, Xu J, Fu X, Peng Y, Linghu E, Tang X. Characteristics and publication status of gastrointestinal endoscopy clinical trials registered in ClinicalTrials.gov. Surg Endosc 2020; 35:3421-3429. [PMID: 32661709 DOI: 10.1007/s00464-020-07786-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Accepted: 07/02/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND AND AIMS This study aimed to examine the fundamental characteristics of gastrointestinal (GI) endoscopy trials and evaluate their publication status. METHODS A cross-sectional analysis was performed in the ClinicalTrials.gov database, and then the PubMed, Medline, Google Scholar, and Embase databases were searched. A dataset containing GI endoscopy clinical studies from ClinicalTrials.gov registered until November 24, 2017, was downloaded. Data of observational and interventional studies were extracted and analyzed. Publications in peer-reviewed journals were examined for completed trials, and factors associated with publication were identified. RESULTS A total of 1338 of 253,777 clinical trials were assigned into GI endoscopy, of which 1018 were interventional and 320 were observational studies. Of all the trials, those from the USA comprised the largest percentage (n = 377, 28.18%). The most common field for registered trials was gastroscopy (n = 436, 32.6%), followed by colonoscopy (n = 215, 16.1%), endoscopic ultrasound (n = 186, 13.9%), endoscopic retrograde cholangiopancreatography (n = 176, 13.1%), and novel endoscopic procedure (n = 103, 7.7%). A total of 501 trials were completed before November 25, 2015, 281 (56.1%) of which were published. The median time from study completion to publication was 21 months (interquartile range, 12-32 months). Trials that were comprised of medium sample sizes (150-1000 subjects), conducted in Europe or Asia and other countries, and single or quadruple blinded were more likely to be published. CONCLUSIONS GI endoscopy is rapidly evolving in clinical applications. Most clinical trials in GI endoscopy are published promptly. These findings demonstrated that investigators are active in performing and communicating the results of clinical trials in the field of GI endoscopy. In the future, the sample size calculation should be presented in detail in the registration system to maintain trial reporting transparency.

A real-time localization system for an endoscopic capsule using magnetic sensors. SENSORS 2014; 14:20910-29. [PMID: 25379813 PMCID: PMC4279517 DOI: 10.3390/s141120910] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/13/2014] [Revised: 08/23/2014] [Accepted: 09/22/2014] [Indexed: 11/21/2022]
Abstract
Magnetic sensing technology offers an attractive alternative for in vivo tracking with much better performance than RF and ultrasound technologies. In this paper, an efficient in vivo magnetic tracking system is presented. The proposed system is intended to localize an endoscopic capsule which delivers biomarkers around specific locations of the gastrointestinal (GI) tract. For efficiently localizing a magnetic marker inside the capsule, a mathematical model has been developed for the magnetic field around a cylindrical magnet and used with a localization algorithm that provides minimum error and fast computation. The proposed tracking system has much reduced complexity compared to the ones reported in the literature to date. Laboratory tests and in vivo animal trials have demonstrated the suitability of the proposed system for tracking a magnetic marker with expected accuracy.

Abstract
Patient safety and quality improvement are increasingly prioritised across all areas of healthcare. Errors in endoscopy are common but often inconsequential and therefore go uncorrected. A series of minor errors, however, may culminate in a significant adverse event. This is unsurprising given the rising volume and complexity of cases coupled with shift working patterns. There is a growing body of evidence to suggest that surgical safety checklists can prevent errors and thus positively impact on patient morbidity and mortality. Consequently, surgical checklists are mandatory for all procedures. Many UK hospitals are mandating the use of similar checklists for endoscopy. There is no guidance on how best to implement endoscopy checklists nor any measure of their usefulness in endoscopy. This article outlines lessons learnt from innovating service delivery in our unit.

Bringing top-end endoscopy to regional australia: hurdles and benefits. DIAGNOSTIC AND THERAPEUTIC ENDOSCOPY 2012; 2012:347202. [PMID: 22991487 PMCID: PMC3443982 DOI: 10.1155/2012/347202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/10/2012] [Accepted: 07/15/2012] [Indexed: 11/17/2022]
Abstract
This paper focuses on recent experience in setting up an endoscopy unit in a large regional hospital. The mix of endoscopy in three smaller hospitals, draining into the large hospital endoscopy unit, has enabled the authors to comment on practical and achievable steps towards creating best practice endoscopy in the regional setting. The challenges of using what is available from an infrastructural equipment and personnel setting are discussed. In a fast moving field such as endoscopy, new techniques have an important role to play, and some are indeed cost effective and have been shown to improve patient care. Some of the new techniques and technologies are easily applicable to smaller endoscopy units and can be easily integrated into the practice of working endoscopists. Cost effectiveness and patient care should always be the final arbiter of what is essential, as opposed to what is nice to have. Close cooperation between referral and peripheral centers should also guide these decisions.
