This study aimed to develop a model that fused multiple features (multi-feature fusion model) for predicting metachronous distant metastasis (DM) in breast cancer (BC) based on clinicopathological characteristics and magnetic resonance imaging (MRI). A nomogram based on clinicopathological features (clinicopathological-feature model) and a nomogram based on the multi-feature fusion model were constructed based on BC patients with DM (n=67) and matched patients (n=134) without DM. DM was diagnosed on average (17.31±13.12) months after diagnosis. The clinicopathological-feature model included seven features: reproductive history, lymph node metastasis, estrogen receptor status, progesterone receptor status, CA153, CEA, and endocrine therapy. The multi-feature fusion model included the same features and an additional three MRI features (multiple masses, fat-saturated T2WI signal, and mass size). The multi-feature fusion model was relatively better at predicting DM. The sensitivity, specificity, diagnostic accuracy and AUC of the multi-feature fusion model were 0.746 (95% CI: 0.623-0.841), 0.806 (0.727-0.867), 0.786 (0.723-0.841), and 0.854 (0.798-0.911), respectively. Both internal and external validations suggested good generalizability of the multi-feature fusion model to the clinic. The incorporation of MRI factors significantly improved the specificity and sensitivity of the nomogram. The constructed multi-feature fusion nomogram may guide DM screening and the implementation of prophylactic treatment for BC.

Introduction: The sharp deterioration in the physical development of the younger generation is worrying. The morbidity of youth has increased by 29.9% compared with the last century. More than 33% of boys and girls, among first-year students with chronic diseases. The aim: Assessing the state of the students’ body by examining the results of a survey among the second- and third-year students of the university using a specially designed questionnaire. Materials and methods: The material on the assessment of the state of health and the characteristics of the organism has been processed by studying the results of a survey of young men and women aged 20-23, obtained on the basis of using the developed questionnaire. Results: Physical development has been studied in accordance with the state of health of the students, as well as a thorough study of a number of criteria: diseases of the musculoskeletal system were 37.1%, 49.7% and 43.45 among boys aged 20, 22 and 23 and respectively 33.3 %, 38.6% and 47.7% among girls in their 20s, 22s and 23s. The morbidity of eye was 18.0%, 3.8% and 9.9% among boys aged 20, 22 and 23 years and 17.7%, 17.1% and 7.7% among girls aged 20, 22 and 23 years. Conclusions: In the structure of morbidities are diseases of the musculoskeletal system, diseases of the nervous system and the organ of vision. Correlation of the characteristics of the level of students’ health and their physical development have indicators on the level of educational adaptation and the number of diseases.
