The First Report of Triple Advanced Synchronous Cancer: Bladder Transitional Cell Carcinoma and Clinically Silent Adenocarcinoma of Prostate and Colon

Multiple synchronous malignancies are believed to be quite rare and their diagnosis and treatment are very challenging for physicians. Co-presence of synchronous bladder and prostate cancers in an elderly individual is not uncommon; however, the simultaneous occurrence of the third cancer - colon cancer - is extremely outlandish. In the present study, the case of an 82-year-old man with a complaint of hematuria is reported who was eventually diagnosed with three synchronous cancers: stage-3 transitional cell carcinoma of the bladder, stage-4 prostate mucinous adenocarcinoma, and stage-3 glandular adenocarcinoma of the colon. The patient underwent total colectomy and radical cystoprostatectomy followed by chemotherapy and radiotherapy. The 2-year follow-up showed promising results with no major complications and the patient's general condition was satisfactory. Although synchronous cancers are not so common, they should not be disregarded in elderly patients especially in those with multiple symptoms.
