Prognostic significance of mucosal transformation factors in patients with Barrett’s esophagus

Abstract

Relevance: PB is a dynamic state, regression and progression of the disease are possible in the same patient against the background of a long period of observation. Materials and methods. The study was conducted on the basis of the MMC BR in Moscow in the period from 2013 to 2023, both retrospectively and prospectively. The diagnosis of BE was established on the basis of the endoscopic picture (according to the Prague criteria) and the data of the morphological study of the biopsy material. As a result of the analysis, 122 patients were selected who were on inpatient and outpatient treatment, as well as dynamic observation. Examination of patients included: clinical data with an assessment of comorbid pathology, endoscopic examination with sampling of biopsy material, morphological, including immunohistochemical studies of biopsy material: determination of mutations in the P53, P63 genes and the nuclear proliferation marker Ki-67. The treatment was carried out in accordance with the clinical recommendations of the Russian Gastroenterological Association based on the developed algorithm and included conservative therapy for BE and identified comorbid pathology, as well as in groups of patients with low-grade dysplasia, endoscopic intraluminal treatment-argon plasma coagulation. Results. Analysis of the results made it possible to conclude that the applied algorithm was highly effective: high scores on the goal achievement scale were achieved in 88% of patients. Moreover, the greatest success was achieved in groups with low-grade dysplasia due to the use of personalized methods of treating patients with BE based on a deep clinical and morphological analysis, including, in addition to generally accepted, gender and age characteristics, assessment of comorbid pathology and the dynamics of P53, P63 and Ki-67 in determining the timing of dynamic follow-up of patients.
