The malignant neoplasm grows rapidly and metastasizes relatively early. The effectiveness of treatment is determined by a number of factors:
● Tumor morphology. With alveolar rhabdomyosarcoma, the prognosis is worse than with its embryonic variant.
● Site localization. Parameningeal localization of the tumor is considered unfavorable (nasal cavity, paranasal sinuses, nasopharynx, middle ear).
● Stage of oncological disease. A small tumor that does not have metastases is cured in 80% of cases. Single metastases reduce the chances of recovery up to 30%.
