Does the Numerical Colour Value (NCV) correlate with preneoplastic and neoplastic colorectal lesions?

Research Progress of Autofluorescence Imaging Technology in the Diagnosis of Early Gastrointestinal Tumors

“…Further improvement of AFI systems is necessary, such as allowing for the elimination of the hemoglobin absorption spectrum. 11 , 12 Although AFI endoscopy is sensitive to autofluorescence produced by tissue, such as normal or cancerous tissue, it remains not as good as the narrow band imaging (NBI) technique in terms of observing submucosal vessels and mucosal morphology. In addition, the image quality of AFI endoscopy is often affected by some confounding factors and needs to be further improved.…”

“…The research included 188 patients with colorectal mucosal lesions diagnosed on WLE and assessed using AFI, and the results showed that the NCV significantly correlated with the histopathology results. 12 Diagnosis of small polyps is important for the prevention of colorectal cancer. Non-polypoid neoplasms are more difficult to detect than polypoid neoplasms by conventional WL colonoscopy, and some have a higher potential for malignancy.…”

Colon cancer – new strategies of treatment

“…Ussing autofluorescence endoscopy together with narrow-band imaging in diagnostics of gastrointestinal tract diseases makes it possible to reach specificity and sensitivity of up to, respectively, 92% and 89% in the detection of intestinal metaplasia, 98.5% and 83% in the detection of dysplastic lesions and 99% and 91% in the detection of early gastric cancer. White light endoscopy applied on its own makes it possible to reach diagnostic specificity and sensitivity of 74% and 83%, respectively [3,4,5,6,7]. In the case of colon cancer, radical surgical removal of the primary tumour is a standard therapeutic procedure.…”

“…Zastosowanie endoskopii autofluorescencyjnej łącznie z obrazowaniem wąskopasmowym w diagnostyce schorzeń przewodu pokarmowego pozwala osiągnąć specyficzność i czułość w granicach odpowiednio 92% i 89% w wykrywaniu metaplazji jelitowej, 98,5% i 83% dla zmian dysplastycznych oraz 99% i 91% w wykrywaniu wczesnego raka żołądka. Endoskopia w świetle białym stosowana samodzielnie pozwala osiągnąć w diagnostyce specyficzność i czułość w granicach odpowiednio 74% i 83% [3,4,5,6,7]. Standardem postępowania terapeutycznego w przypadku raka jelita grubego jest radykalne chirurgiczne usunięcie guza pierwotnego.…”
