Abstract

An important factor in assessing tumor status for determining therapeutic and surgical tactics is the study of its morphological structure. In particular, preoperative differentiation/grading of colorectal adenocarcinomas is very important for the adjustment of neoadjuvant therapy, surgical technique choice and survival prediction. To achieve the maximum benefit and to avoid unnecessary side effects, the ability to distinguish high-grade from low-grade colorectal adenocarcinoma, as well as identification of patients with high recurrence risk before the possible initiation of treatment will increase the quality and duration of patients' life. Taking into account the peculiarities of the biology of intestinal cancer, optical coherence elastography, as a method of studying tissue structure at a shallow depth, may be promising in the study of colorectal adenocarcinoma. Possibilities of optical coherence elastography in differentiating low-grade and high-grade types of colorectal adenocarcinoma are demonstrated in this study. The reported results are based on revealed qualitative criteria for assessment of OCE images in combination with quantitative statistically significant differences in characteristic stiffness values for low-grade and high-grade colorectal adenocarcinomas.
