Common complications of bladder cancer include metastasis, anemia, hydronephrosis, urethral stricture, and urinary incontinence. Prognosis is generally good, and the 5-year survival rate is approximately 77.4%. The prognosis varies with the stages of tumor; carcinoma in situ have the most favorable prognosis.
Natural History, Complications, and Prognosis
- The symptoms of bladder cancer usually develop in the 6th and 7th decade of life, and start with symptoms such as hematuria, difficulty urinating and dysuria.
- Based on data from 2005-2011, the 5-year survival rate of patients with bladder cancer is approximately 77.4%.
- Between 2004 and 2010, the 5-year relative survival of patients with bladder cancer was 79.1%.
- When stratified by age, the 5-year relative survival of patients with bladder cancer was 83.8% and 74.1% for patients <65 and ≥ 65 years of age respectively.
- The survival of patients with bladder cancer varies with the stage of the disease. Shown below is a table depicting the 5-year relative survival by the stage of bladder cancer:
|Stage||5-year relative survival (%), (2004-2010)|
- Shown below is an image depicting the 5-year conditional relative survival (probability of surviving in the next 5-years given the cohort has already survived 0, 1, 3 years) between 2004 and 2010 of bladder cancer by stage at diagnosis according to SEER.
