title: [Clinico-statistical study on bladder tumor].
abstract: A survey was performed on 277 cases of bladder tumor including 221 males and 56 females (3.9:1), treated in the Department of Urology, Kyoto Prefectural University of Medicine. The result was as follows. The age distribution was from 24 to 86 years old with the average of 65.7. Histologically, 2 cases were diagnosed as transitional cell papilloma, 53 cases as transitional cell carcinoma G1, 111 cases as G2, 88 cases as G3, 16 cases as GX, 5 cases as squamous cell carcinoma and 2 cases as adenocarcinoma. As to the relationship between the grade and the stage, all cases of papilloma or G1 were superficial, while 7.2% of G2 and 45.5% of G3 were invasive, showing a close correlation. As to the relationship of cystoscopic findings and the stage, invasive tumors occupied 1.7% of tumors less than 1 cm in diameter, 16.7% of those 1 to 3 cm, 48.0% of 3 to 5 cm and 41.7% of more than 5 cm in diameter. Also 7.1% of papillary pedunculated tumors, 57.1% of non-papillary pedunculated, 21.7% of papillary sessile and 53.5% of non-papillary sessile were invasive. Thus cystoscopic findings of tumors correlated with the stage. The 5 year survival rates were 61.7% in all cases, 81.4% in pTa, 70.5% in pT1, 58.7% in pT2, 50.0% in pT3a, 32.6% in pT3b and 25.0% in pT4. The stage of tumors reflected the prognosis well. Careful cystoscopy and accurate grading were thought to be helpful for correct staging and for choosing a suitable treatment.
