The Electronic \u0000Registry of Oncological Patients of the Republic of Kazakhstan (RK) reports 27 morphologically verified cases of medulloblastoma in 2021, 18 of \u0000them in children (66.6%). \u0000The aim was to show the feasibility of conducting a molecular genetic study to clarify the diagnosis of brain tumors using a clinical case as \u0000an example. \u0000Methods: The article describes a clinical case of a patient with medulloblastoma.

About 30-70% \u0000of breast cancer cases in men develop against the background of gynecomastia, particularly its nodular form. The biology of the disease differs in \u0000men, but the approaches to diagnostics and treatment are usually extrapolated from those used in women. \u0000This study aimed to demonstrate the results of each stage of a male patient with BC diagnostics and treatment. \u0000Methods: The article presents a clinical case of a male patient diagnosed with «Cancer in the right breast St III (T4NxM0), Edematous-infiltrative form with an intraductal component, upper outer localization.

The peak incidence of bone tumors falls at a socially significant age: with osteosarcoma and Ewing’s sarcoma – 10-25 years, with chondrosarcoma – 35-40 years. Bone \u0000sarcomas are the most aggressive human MNs. This urges to determine the prognostic factors of the disease, timely assess the treatment \u0000effect, and identify possible relapses. \u0000The study aimed to improve the early diagnosis of bone sarcomas, to improve and increase the oncological alertness of doctors by \u0000establishing the trends in bone sarcoma incidence and mortality in Kazakhstan in 2010-2019 and this disease incidence and mortality in \u00002019 by age, gender, bone tumor histotype and region of the country. \u0000Materials and Methods: This study included the data of all patients registered at the Electronic Registry of Oncological Patients \u0000(EROP) of the Republic of Kazakhstan in 2010-2019 with a “bone sarcoma” diagnosis (ICD-10 code: C40-C41). The incidence of bone \u0000sarcomas was presented as absolute and crude rates per 100,000 population. Absolute standardized morbidity and mortality were calculated using the World Standard.
