Radical cystectomy is considered the first choice for the treatment of muscle-invasive bladder cancer. However, for some patients who have lost the indications for surgery, external beam radiotherapy is a non-invasive and effective treatment.
A 76-year-old patient with bladder cancer who had serious comorbidities and could not tolerate surgery or chemotherapy came to the Wuwei Heavy Ion Center. He received carbon ion radiotherapy (CIRT) with a whole-bladder dose of 44 GyE and tumor boost of 20 GyE. When he finished CIRT, his bladder cancer-related hematuria completely disappeared, and computed tomography examination showed that the tumor had obviously decreased in size. At the 3-mo follow-up, the tumor disappeared, and there were no acute or late adverse events. CIRT was well tolerated in this patient.
CIRT may allow for avoiding resection and was well tolerated with curative outcomes.
Core Tip: This case report is of a bladder cancer patient who received carbon ion radiotherapy (CIRT). The patient tolerated CIRT well. After the completion of CIRT, the hematuria associated with bladder cancer disappeared completely, and computed tomography examination showed that the tumor was significantly reduced. During the 3-mo follow-up, the tumor disappeared and there were no acute or late adverse events.
