All cases of superficial @entity150 treated in 1991 at the urology department of La Piti   hospital were reviewed to study the course of superficial @entity150 with regard to the risk of muscle infiltration and the value of endoscopic follow-up. In 1991, 73 @entity1 (63 @entity1 and 10 @entity1 ) with a mean age of 64 years had TUR for superficial @entity150 . @entity1 had repeated cystoscopy at 3 and 6 months and then on a yearly basis for 5 years. Fourty-eight @entity1 had TIS @entity5 , and 19 @entity1 had T1 @entity5 . Five @entity1 were lost to follow-up. Sixty-eight @entity1 were followed for 5 years. Of 48 @entity1 with stage TIS @entity5 , 39 (81.5%) did not show any deterioration at histological examination, eight @entity1 (16.5%) had infiltration of the lamina propria by @entity5 ( @entity2558 ) and the @entity5 invaded muscle in one @entity1 (2%). Of the 19 @entity1 with stage T1 @entity5 at the first TUR eight (47%) had no pathologic deterioration, but nine (53%) developed @entity11090 (pT2). Two @entity1 were lost to follow-up. Invasion of the lamina propria present at diagnosis or during the subsequent course is considered to be an indicator of high risk of progression to muscle invasive disease (over 50% of cases). The prognostic accuracy of both the grade and stage needs to be enhanced using molecular markers.
