Bladder Cancer T4a
Reviewed by Oncology Team, HealOnco | Last updated: 2026-04
What T4a Means
Invasion into prostatic stroma, seminal vesicles, or uterus/vagina.
Treatment Approach for T4a
Neoadjuvant chemotherapy mandatory but disease likely unresectable. Palliative chemotherapy or radiation for symptom control. Immunotherapy (atezolizumab, pembrolizumab) in cisplatin-ineligible patients.
Survival Rates and Prognosis
The 5-year survival rate for bladder cancer at T4a is approximately 5-year: 15-25%. Survival rates are statistical averages drawn from large patient populations and may not reflect your individual outcome. Factors that influence your specific prognosis include your age, overall health, tumour biology, and how well the cancer responds to treatment.
Important: These numbers are drawn from historical data. Newer treatments available today may improve outcomes beyond what published statistics show. Discuss your individual prognosis with your oncologist.
