Urachal carcinoma is an uncommon cancer whose rarity has precluded its study and evidence-based management strategies are lacking. This study assessed all urachal carcinomas in Ireland and clinical parameters in order to improve understanding. Urachal carcinomas diagnosed from 1994 to 2011 were identified from the National Cancer Registry in Ireland. Data obtained included patient age, gender, diagnostic year, pathology, tumor stage, patient treatment strategies and survival. Twenty-six urachal carcinomas were identified, the majority being adenocarcinoma. This comprised 0.3% of all invasive bladder tumors. Patients were predominantly male (62%) and over 50 years of age (58%). Twenty-two patients (85%) underwent surgery, with only six (23%) undergoing chemotherapy. On average, median overall survival was 2.6 years (range 0-15.2 yrs). Survival was longer in women (5 vs. 1.9 yrs), patients under 50 years of age (3.6 vs. 1.9 yrs), those without confirmed metastasis (4.1 vs. 0.7 yrs) and those who received chemotherapy (3.6 vs. 2.6 yrs). The overall survival of urachal carcinoma in Ireland is less than expected from published literature. This study highlights the need for centralization of rare tumors with international collaboration to identify the optimal treatment strategy and improve outcome
