description | Background: Currently, there is an increase in cancer among the elderly. Despite the obvious advances in the healthcare related to the diagnosis of the disease and its treatment, oncopathology occupies a high position in the structure of the overall morbidity. Clinical case description: Patient T., 62 years old, came to an internist with the complaints of constant pulling pains in the lower abdomen, a stool disorder in the form of alternating constipation and diarrhea, presence of blood in the stool over the past 6 months, a weight loss of 8 kg over the past 4 months. She was examined independently two years ago, when the disorders of the gastrointestinal tract appeared for the first time, which she associated with constant stressful situations at work. According to the study results, no significant deviations were found. The patient also underwent 16s-RNA sequencing of the intestinal microbiome, which revealed significant changes in many clusters of bacteria (a decrease in the quantitative composition of Lactobacterium, Bifidobacterium, Akkermansia, Faecalibacterium, which is the main representative of the normal intestinal flora, that may indicate a decrease in the protective barrier function of the colonic mucosa, an increase in Fusobacterium, as well as other representatives of the pathogenic flora). Presently, within the framework of laboratory and instrumental studies, the following diagnosis was established: "Malignant formation of the colon (colorectal cancer). T3M0N1". A repeated study of the intestinal microbiota was carried out, according to the results of which an increase in Fusobacterium up to 7.5% was observed, along with a sharp decrease in the representatives of the normoflora (1%). Conclusion: Changes in various bacterial clusters of the intestinal microbiota can serve as an early marker for the verification of malignant neoplasms of the large intestine. Determining the amount of Fusobacterium in the intestinal microbiome can be an indicator of the first diagnostic line, which helps to identify the pathological process at the stage of precancer, take timely therapeutic measures, improve the quality of life, and increase its longevity. |
