Myeloblastoma is one of the most common childhood tumors. Among children under 10 years of age, the incidence rate is about 20% to 30% of all tumors. The peak age of onset is 5 years, and men are slightly more than women. The tumor is located in the posterior cervical fovea, near the cerebellar vermis and the fourth ventricle midline, and advanced tumors spread in the cerebrospinal fluid. Typical clinical manifestations are mainly related to the increased intracranial pressure caused by tumor occupying the posterior cranial fossa and blocking the fourth ventricle or midbrain aqueduct: headache, nausea, vomiting, blurred vision, and balance function caused by tumor compression on the cerebellum Obstacles, such as walking instability, ataxia, etc.
Terapi péso proton
Ku alatan éta, dibandingkeun sareng radioterapi konvensional, terapi péso proton ngagaduhan ciri fisik sareng biologis anu langkung saé, sareng ngagaduhan dosis radiasi anu cekap pikeun ngahontal tumor dina bagéan awak anu langkung jero. Ion beurat sareng proton tiasa ngahontal jaringan jero 30 cm handapeun kulit, anu sacara signifikan ningkatkeun kamampuan pikeun ngendalikeun tumor; dibandingkeun sareng metode radiasi tradisional, énergi radiasi ngahontal lokasi tumor tiasa ningkat pisan (péso proton tiasa ningkat ku 20%), anu sacara signifikan ngirangan periphery tumor. Karuksakan sareng efek samping tina jaringan normal; ngirangan karacunan jaringan normal kalayan aplikasi radioterapi sareng kémoterapi sakaligus; sacara signifikan nyingkat kursus pangobatan ku ningkatkeun dosis radiasi sadidinten; ngirangan kajadian tumor primér kadua.
