Limited Effectiveness

AbstractEarly detection and treatment of preneoplastic lesions represents an obvious option to reduce morbidity and mortality from lung malignancies. Until now, radiological detection, sputum cytology, and autofluorescence have shown limited effectiveness as screening methods. Novel technologies such as Narrow Band Imaging (NBI) are showing promising results, but new studies are still needed to evaluate their use as screening methods. Together with early detection, adequate methods of lesion treatment, such as argon plasma coagulation, are needed. This case report concerns a 45-year-old man who was referred for bronchoscopy after his annual checkup. Using NBI technology, a preneoplastic lesion was identified, and treated using argon plasma coagulation. Our experience has shown us that both NBI screening and argon plasma coagulation are very promising, easily implemented, methods.

High Resolution Images

Transoral robotic surgery (TORS) is a less invasive treatment that is becoming popular all over the world. One of the most important factors for achieving success in TORS is the ability to determine the extent of resection during the procedure as the extent of resection in the laryngopharynx not only affects oncological outcomes but also directly affects swallowing and voice functions. Magnifying endoscopy with narrow band imaging (ME-NBI) is an innovative optical technology that provides high-resolution images and is useful in detecting early superficial pharyngeal cancers, which are difficult to detect by standard endoscopy. A 55-year-old male with superficial oropharyngeal cancer has been successfully treated by combining MB-NBI with TORS and MB-NBI was useful in determining the extent of resection. ME-NBI with TORS will make it possible to achieve a higher ratio of minimally invasive treatment in pharyngeal cancer.

Narrow band imaging is considered a significant improvement in the possibility of detecting early mucosal lesion of the upper aerodigestive tract. Early detection of mucosal neoplastic lesions is of utmost importance for patients survival. There is evidence that, especially in patients previously treated by means of curative radiotherapy or chemoradiotherapy, the early detection rate of recurrent disease is quite low. The aim of this study was to prove whether the videoendoscopy coupled with NBI might help detect recurrent or secondary tumors of the upper aerodigestive tract. 66 patients previously treated by means of RT or CRT with curative intent were enrolled in the study. All patients underwent transnasal flexible videoendoscopy with NBI mode under local anesthesia. When a suspicious lesion was identified in an ambulatory setting, its nature was proved histologically. Many of these changes were not identifiable by means of conventional white light (WL) endoscopy. The accuracy, sensitivity, specificity, and positive and negative predictive value of the method are very high (88%, 92%, 76%, 96%, and 91%, resp.). Results demonstrate that outpatient transnasal endoscopy with NBI is an excellent method for the follow-up of patients with carcinomas of the larynx and the hypopharynx primarily treated with radiotherapy.

<p class="abstract"><strong>Background: </strong>Head and neck mucosal lesions are difficult to diagnose at early stage; therefore, they usually present at an advance phase. Narrow Band imaging (NBI) first came to use around 2005 and became one of the most used technologies for image enhanced endoscopy.</p><p class="abstract"><strong>Material and method: </strong>In order to identify best method for early detection of mucosal lesion of head and neck, we examined patients with suspected lesions first under white light endoscopy then under NBI endoscopy. Patients under-went biopsy thereafter, and results were compared. Our aim was to evaluate the role of NBI as a screening tool in the early detection of mucosal lesions of head and neck.</p><p class="abstract"><strong>Result:</strong> It was observed that NBI is useful tool in identifying mucosal lesions of head and neck early. 71 patients were included in our study and it was observed that NBI endoscopy shows 100% sensitivity, 96.36% specificity and 97.18% accuracy in identifying benign lesions. It shows 100% sensitivity, 94.74% specificity and 98.59% accuracy in identifying malignant lesions.</p><p class="abstract"><strong>Conclusion:</strong> In our study we came to conclusion that NBI is very promising tool for early screening purposes of mucosal lesions of head and neck which were missed in routine examination.</p>
