Purpose : The identification of factors present at the time of initial evaluation may be
important to predict the prognosis in patients with superficial bladder carcinoma.
Attempts were made to identify predictive factors of recurrence and progression.
Materials and Methods : This study included twenty seven patients with superficial
bladder tumor(pTa-pTl) who had no recurrence within 5 years. A comparative
non-randomized study was performed of a control group of twenty six patients with
same superficial bladder tumor who had recurrence within 1 year after transurethral
resection of bladder tumor(TURBT) was done. Between the former and the latter
patients cumulative and multivariate analyses were performed to estabilish predictive
factors of pathological recurrence and progression.
The resected tumors were immunohistochemically stained with anti-lamin rabbit serum
to evaluate the presence or absence of basement membrane breakage, the vascular
and/or lymphatic invasion, and to count number of neovascularizasion.
Results : In superficial bladder carcinoma, invasion of basement membrane, grade,
invasion of lymphatics and vessels, and neoangiogenesis were significant factors
affecting recurrence and progression, and these factors acted independently.
Conclusions : These factors used to predict recurrence and progression of superficial
bladder tumor were thought to be the important risk factors. These results suggested
that close follow-up and aggressive treatment such as BCG instillation should be
considered for the treatment of superficial bladder cancer with unfavourable prognostic
factors.
