Aim. To improve the effectiveness of tumors and risk factors detection in reducing time costs at the pre-medical stage using a robotic complex.

Methods. To achieve this goal, the previously created robotic complex with a program for self-questioning, taking into account gender, has been improved. A portable USB microscope was built into the complex’s housing to transmit images of pathological changes of visible localizations to the touch screen. The survey and examinations were conducted by clinical residents and students of the “case-control” type in 1638 patients at the Novgorod Regional Clinical Oncological Dispensary (in 2019–2021) as part of the Doors Open Days. The average age of patients was 54.6±8.9 years, including 703 men and 935 women. Descriptive statistics methods of Statistica 6.0 software were used. Qualitative characteristics showed as absolute number and the relative value in percentage (%). The differences were considered statistically significant at p ≤0.05.

Results. The use of the complex allowed us to suspect cancer risk factors in 9.03±1.3% patients, of which 31.08±1.8%, or 2.8±2.1% (p=0.017) of the total patients with the further examination was able to confirm oncology-related findings. Patients complained of discomfort in the stomach (59 people) underwent a breath test built into the program of the complex, according to the results of which helicobacteriosis was detected in 29 patients. In 17 patients with fibrogastroscopy, intestinal metaplasia was subsequently established, in 4 — gastric ulcers, 3 of which had malignancy.

Conclusion. The use of a robotic complex-2 saves the time of a doctor of a “lean” polyclinic and improves the effectiveness of identifying cancer risk factors and early-stage cancer.
