“…Quantitative processing of 3D OCT images was demonstrated to significantly increase the diagnostic performance of the method for in situ detection of bladder carcinomas [3][4][5]. Meanwhile, an analysis of a large number of works on the use of OCT for bladder cancer visualization by Hale and Deem [6] indicated that cases of false positive cancer diagnoses are fairly typical for OCT against a background of severe inflammation as well as in cases of the diagnosis of cancer in the region of the postoperative scar.…”

The aim of the study is to demonstrate the potential of cross-polarization optical coherence tomography (CP OCT) as a minimally invasive real-time technique for detection of bladder cancer against a background of severe inflammation.Materials and Methods. For the verification of CP OCT diagnostic data related to the condition of collagen comparison with highresolution microscopy inspection was performed and correlation of the results was calculated. The CP OCT study was performed on samples of tissue with muscle-invasive urothelial carcinoma T 2-3 N 0-х M 0 (G2, 3) in 18 patients ranging in age from 50 to 64 obtained in course of cystectomy with urine diversion into the intestinal vessel. In total, 60 regions of interest were selected and divided into four groups in accordance with the results of the histological analysis: areas with mild inflammation (group 1, control), 12 areas; areas with severe inflammation (group 2), 18 areas; areas with poorly differentiated urothelial carcinoma with invasion into the muscular layer (group 3), 24 areas; areas with cancer recurrence at the post-operative scar (group 4), 6 areas. Tissue changes at micro-structural level registered by CP OCT were investigated in detail with high-resolution microscopy (nonlinear microscopy and atomic force microscopy). Quantitative processing of all the obtained images enabled their direct comparison.

“…Its ability to image beneath the surface epithelium has made it an attractive target for study in the evaluation of SSIM. A single-center cross-sectional study found presence of SSIM by OCT in 72% of patients not treated for BE, and in 63% of patients who had achieved CE-IM after RFA, with a significantly lower number of buried glands per patient in the post CE-IM group (75). VLE is a commercially available system based on frequency-domain OCT. A study from the Netherlands published in 2016 evaluating the detection of buried glands after RFA (in patients with HGD or intramucosal EAC) using VLE reported that out of 17 patients, 13 were found to have subsquamous glandular structures by VLE.…”

Barrett's esophagus (BE) is a premalignant condition that increases the risk of esophageal adenocarcinoma (EAC). Significantly more common in the Western world, risk factors include increased age, male sex, white race, gastro-esophageal reflux disease (GERD), central obesity, and cigarette smoking. The rates of progression to cancer depend on the grade of Barrett's dysplasia. Screening for BE is recommended in patients with GERD and additional risk factors. Endoscopic surveillance of patients with BE likely improves overall outcomes. Advanced endoscopic imaging can help increase the efficiency of current endoscopic surveillance.Endoscopic therapy is safe and effective for the treatment of dysplastic BE and intramucosal EAC, but ongoing surveillance following treatment is necessary. This review will cover screening, surveillance, advanced imaging, chemoprevention, endoscopic treatment, and post-treatment surveillance of BE.
