Abstract Purpose: The present study sought to identify prognostic factors for breast cancer survival and recurrence using a machine learning approach and electronic medical record data.Methods: We used a machine learning technique called feature selection to identify factors influencing breast cancer prognosis, and factors affecting survival and recurrence in a Cox regression model. Results: History of relapse, type of surgery, diagnostic route, SEER stage, and hormone therapy all affected breast cancer survival. Recurrence of breast cancer was affected by age, history of diabetes, breast reconstruction, pain, breast lumps, nipple discharge, and the presence of other symptoms. According to the survival analysis based on feature selection, patients with diabetes had a significantly higher risk of early recurrence of breast cancer (hazard ratio, 4.8; 95% confidence interval, 2.04–11.2, p < 0.05). Conclusions: The present study identified several factors associated with breast cancer prognosis. While survival was affected by the diagnostic route, recurrence was primarily influenced by breast cancer symptoms and other underlying health conditions. A more accurate and standardized model considering time-to-event data could be developed in the future to evaluate prognostic factors and predict prognoses, and for clinical validation

Postmastectomy reconstruction has been shown to be oncologically safe, but few studies have investigated factors influencing the type of reconstruction chosen, if at all. Records of female patients with stages 0 to 3 breast cancer undergoing mastectomy at a large academic institution between January 2010 and March 2018 were reviewed. Nine hundred sixty patients were included in this cohort; 784 patients had reconstruction. Younger age, earlier disease stage, private insurance, no history of diabetes, and bilateral mastectomy (BM) were associated with reconstruction. On multivariate analysis, younger age, BM, private insurance, and earlier disease stage predicted reconstruction. Of reconstruction patients, 453 had implants. Race, BMI, and later disease stage influenced the type of reconstruction; on multivariate analysis, higher BMI and later disease stage predicted flap reconstruction. Younger age, BM, private insurance, and earlier disease stage were associated with reconstruction, but the type of reconstruction was affected primarily by BMI and disease stage.

Studying the current state of cartography and ways of further developing the industry, the role of the map in the future of the society, new methods of promoting cartographic products is impossible without a deep scientific analyzing all the paths, events and factors influencing its formation and development throughout all the historic steps of cartographic production in Russia. In the article, the history of cartographic production in Russia is considered together with the development of private, state and military cartography, since, despite some differences, they have a common technical, technological and production basis. The author describes the stages of originating, formation and growth of industrial cartographic production from the beginning of the XVIII century until now. The connection between the change of political formations and technological structures with the mentioned stages of maps and atlases production is considered. Each stage is studied in detail, a step-by-step analysis was carried out, and the characteristics of each stage are described. All the events and facts are given in chronological order, highlighting especially significant moments influencing the evolution of cartographic production. The data on the volumes of printing and sales of atlases and maps by commercial and state enterprises are presented. The main trends and lines of further development of cartographic production in Russia are studied.
