In Russia, for more than 10 years, within the framework of national projects, the activities have been carried out aimed at restructuring of the primary and specialized (including high-tech) medical care, as well as strengthening of primary health care directed at early detection of malignant neoplasms. The study was aimed to evaluate the effectiveness of the patient examination rooms for women in improvement of the adjusted cumulative survival of patients with gynecologic malignancies detected actively in 2005–2015 in the Chelyabinsk Region. Using the Population Based Cancer Registry (PBCR) of the Chelyabinsk Region database, the adjusted cumulative survival calculation for patients with cervical cancer (389), uterine corpus cancer (373) and ovarian cancer (161) detected actively in the patient examination rooms of the Chelyabinsk Region (treatment group), as well as for cervical cancer (395), uterine corpus cancer (380) and ovarian cancer (163) detected in patients who sought medical assistance (control group), was performed for the first time. The staging of cervical cancer detected in the examination rooms in 2010–2017 was characterized by the high proportion of I/II stage tumors compared with the rest of patients’ population of the Chelyabinsk Region (an average of 50.8 and 46.1% respectively). For uterine corpus cancer the average proportion was 85.5 and 82.0% respectively, and for ovarian cancers it was 42.0 and 37.4% respectively. Analysis of the PBCR of the Chelyabinsk Region for a 10-year period revealed the 5-year adjusted cumulative survival improvement in the actively detected cervical cancer patients compared to the control group (62.3 and 55.8%) respectively (p = 0.11). In patients with uterine corpus cancer, it was 82.0% for the main group and 70.4% for the control group (p = 0.001). In ovarian cancer patients, no significant differences in the 5-year adjusted cumulative survival were observed (47.5% in the main group, 43.2% in the control group) (p = 0.49). Thus, the patient examination rooms are the effective model of the cancer secondary prevention available in the Chelyabinsk Region.
