case_images: TURBT pathology indicated that the patient has stage-TaG1 UBC ( Figure 1A ). Between July 2016 and May 2018, TURBT was repeated five times due to cancer recurrence and progression ( Figures 1B-F ).

case_images: Unfortunately, after four cycles treatment, the patient's abdominal CT ( Figure 2 -6) showed that the treatment had failed and the patients' condition continued to deteriorate. CT ( Figure 2 ) and PR was observed. Currently, the cancer has been stable for over 11 months and the patient is still being followed up.

case_images: Unfortunately, after four cycles treatment, the patient's abdominal CT ( Figure 2 -6) showed that the treatment had failed and the patients' condition continued to deteriorate. To provide further treatment to this patient, we performed genetic sequencing and molecular characterization confirmed the presence of FGFR3, PIK3CA, and TP53 mutations in the patient ( Figure 3 ).
