UNASSIGNED: The current study reports the case of a @entity5 treated with modified @entity15929 ( @entity15929 ) radiotherapy. A 45-year-old female presented to the emergency department complaining of left @entity490 and @entity221 . A computed tomography scan detected a retroperitoneal @entity5 of 12*16*16 cm, and a biopsy revealed a poorly-differentiated @entity420 . The @entity1 was diagnosed with a large @entity420 originating from the left ureter, with no distant @entity3 . Due to the @entity1 's poor physical condition, surgery was not recommended, and the @entity1 was referred to the Department of Radiation Oncology (Yamagata University Hospital, Yamagata, Japan). Modified @entity15929 radiotherapy was administered following the acquisition of written consent from the @entity1 . The total irradiation dose to the center of the @entity5 and to the surrounding healthy tissue was    96 Gy/33 fractions and <60 Gy/33 fractions, respectively. At the end of the radiotherapeutic course, the @entity5 volume was reduced by >= 80%, and the @entity41 was surgically resected. As a result of the resection, a complete pathological response was confirmed; the @entity1 has been recurrence-free for >3 years with no complications. Modified @entity15929 radiotherapy may be safely administered, with favorable outcomes. Complete recovery can be achieved with this technique, even in a @entity1 with a large radioresistant @entity5 .
