抄録: | 過去15年間に京都大学泌尿器科を初診した表在性膀胱癌205症例中, 深部浸潤癌や転移癌へ病態変化したものは35例であった.初発腫瘍が多発, grade 2以上, stage T1症例, 尿細胞診陽性症例は病態変化に関して高危険度群であった We analyzed the clinico-pathological features of the initial tumors in 205 patients with superficial bladder cancer, admitted to Kyoto University Hospital between 1974 and 1988, to investigate the prognostic factors for progression to the muscle invasive disease or metastasis. Of 205 patients, 35 (17%) exhibited muscular invasion alone (12 patients) and/or metastasis (23 patients). Tumor multiplicity, higher grade and positive urinary cytology were the significant risk factors for later malignant progression. Expression of A, B, H-blood group isoantigens in the bladder tumor were significantly decreased from the onset in the patients with initially T1 tumor but not in those with Ta tumor. Significant loss of expression was also found at the time of progression in the initially Ta cases. Thus, loss of A, B, H-blood group antigen expression seems to be correlated with the malignant potential of superficial bladder cancer. However, more feasible and reliable diagnostic markers such as molecular genetical and biochemical markers remain to be developed to predict the malignant potential of the superficial bladder cancer. |
