Abstract
Objective: Bladder cancer (BC) is the most common malignancy of the urinary system and the incidence of BC variesregionally. Bladder cancer is more common in men than in women. Tumor stage and grade are the most importantprognostic factors of BC. We aimed to describe the patterns of BC presentation and to examine the differences in thedistribution of prognostic factors by gender, age, tumor size, and involvement region.Method: The patients diagnosed with BC (non-muscle invasive or muscle-invasive BC) were included. Intravesicaltreatment, tumor diameter, pathological grade, tumor involved area and tumor stage were recorded as variables. Thesurvival rates of the patients were calculated for diverse clinical and pathological findings.Results:In a total of 124 patients, 23 (18.5%) of patients were female and 101(81.5%) of patients were male, themedian age of all patients was 64 (IQR: 21-92). There were 36 % (41) patients in early-stage (stage 0 or stage insitu),50.9 % (58) patients in stage 1, 7% (8) patients in stage 2, 4.4 %(5) patients in stage 3 and 1.8% (2) patients were instage 4. There were significantly different OS rates of patients with BC in different stages (p2.5cm (group 2). There was asignificant difference between the overall survival rates of group 1 and group 2(p=0.02). There were 55 patients withlow-grade BC and 38 of patients with high-grade BC, and the difference between their survival rates was statisticallysignificant (p=0.001).Conclusions: Tumor stage, tumor diameter, and grade were demonstrated and confirmed as the crucial prognosticfactors of bladder cancer. Additionally, lateral walls of bladder constitute the most commonly involved area, but theirroles in the disease course still remain unclear.
Özet
Amaç: Mesane kanseri (MK), üriner sistemin en sık görülen malignitesidir ve görülme sıklığı bölgelere göre değişmektedir. Mesane kanseri erkeklerde kadınlardan daha yaygındır. Tümör evresi ve derecesi, MK'nin en önemli prognostik faktörleridir. Bu çalışmamızda mesane kanserinin klinik ve patolojik özelliklerini belirlemeyi, ayrıca bu özelliklerin prognostik değerleri ve hasta sağkalımı üzerine etkilerini incelemeyi amaçladık. Yöntemler: Çalışmaya mesane kanseri tanısı konan hastalar (kas tutulumu olmayan veya kas tutulumu olan) dahil edildi. Mesane içi tedavi tipi, tümör çapı, patolojik derece, tümörün oluştuğu bölge ve tümör evresi değişken olarak kaydedildi. Hastaların sağkalım oranları; tümör çapı, tümörün histopatolojik derecesi ve hastalığın evresi gibi çeşitli parametrelerle ilişkilendirildi. Bulgular: Toplam 124 hastanın 23'ü (%18,5) kadın, 101'i (%81,5) erkek, tüm hastaların ortalama yaşı 64 idi (21-92). Erken evrede %36 (41) hasta (evre 0 veya evre insitu), evre 1'de %50,9 (58) hasta, evre 2'de %7 (8), evre 3'te %4,4 (5) hasta ve evre 4’te %1,8'i (2) hasta saptandı. Evreler arası sağkalım oranları arasındaki fark istatistiksel olarak anlamlı idi (p
