It is the most common form of soft tissue sarcoma in children and adolescents, although it can also occur in adults. Rhabdomyosarcoma is classified into several morphologic subtypes, including alveolar, embryonal, capacitive, and anaplastic forms, which can occur in various anatomical sites, such as the head, neck, genitourinary system, and other tissues. The prognosis for patients with rhabdomyosarcoma varies depending on age, stage of disease, and tumor differentiation, but is generally highly aggressive and requires a multidisciplinary approach to treatment.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-flat ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Rhabdomyosarcoma was first described in medical literature in the mid-19th century. In 1854, German physician Rudolf Virchow described malignant tumors associated with muscle tissue. In the 1920s, researchers began to classify different types of sarcomas, among which rhabdomyosarcoma was singled out. Over the following decades, significant progress was made in understanding the biology of the tumor, its molecular markers, and mechanisms of metastasis. In the 1970s, the first chemotherapy regimens were developed, which significantly improved patient outcomes, increasing survival. <\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Rhabdomyosarcoma accounts for approximately 3% of all childhood cancers and is most commonly diagnosed in children under 5 years of age. Epidemiological data show that the incidence among boys exceeds that among girls, which is due to differences in sex predisposition. According to various studies, the incidence is between 4 and 5 cases per 1 million children under 14 years of age. More than 60% cases are reported in younger children, with peak incidence in children aged 2 to 6 years. It is important to note that key geographic differences in prevalence have not been established, and cases are seen worldwide.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to modern research, genetic factors play a significant role in the development of alveolar rathematomyosarcoma. In particular, patients with hereditary syndromes such as Li-Fraumeni syndrome and Neufeld syndrome have an increased risk of developing this disease. At the morphological level, important markers are mutations in the TP53, PAX3, PAX7 and FGFR4 genes, which are present in many cases of alveolar rathematomyosarcoma. There are studies confirming the presence of chromosomal abnormalities, especially deletions and translocations, which makes them potential targets for molecular targeted therapy. <\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are various risk factors that may contribute to the development of rhabdomyosarcoma.
