Аннотация
BACKGROUND: Patients with esophageal squamous cell carcinoma (SCC) have a poor prognosis mostly due to the late diagnosis. A morphological method is still the main diagnostic method for SCC. The aim of the study was to find out which histological criteria, namely Western or Japanese criteria, for early stage SCC are used by pathologists in Ukraine as compared with their Japanese colleagues.
METHODS: 14 Ukrainian and 6 Japanese pathologists have participated in this study. Virtual slides for research were provided by National Cancer Research Center (Tokyo, Japan) in 2018. Each of the pathologists has used these slides and presented the conclusion via the Internet.
RESULTS: Essential diagnostic discrepancies were revealed: a number of biopsy specimens was diagnosed by Japanese pathologists as "noninvasive carcinoma", while Ukrainian pathologists classified the specimens as high-grade or low-grade dysplasia, indefinite for neoplasia, or reactive/regenerative lesions.
CONCLUSION: The adoption of a unified concept of criteria for non-invasive (intraepithelial) carcinoma underlies early endoscopic/surgical treatment, which significantly increases the survival rate of patients with SCC. A solid common approach to the diagnosis between Western and Japanese pathologists, as well as endoscopists, is necessary to ensure timely treatment and increase survival rate of patients with SCC.
