Transitional cell bladder carcinoma is characterized by a dichotomous, multichronotopic natural history. Low and moderate grade Ta lesions frequently recur, yet rarely invade, and carry an excellent prognosis with currently available treatments. High grade Ta lesions, tumors with lamina propria inva

โฆ Synopsis
Non-invasive transitional cell carcinoma (TCC) occurs as two distinct growth patterns, papillary and non-papillary (flat), which display significant differences in biologic potential. Papillary carcinoma usually presents as a low-grade lesion which frequently recurs multiple times prior to invasion; conversely, non-papillary (flat) carcinoma in situ is usually high-grade at presentation (carcinoma in situ) and frequently associated with invasion. These lesions may occur together, although papillary cancer is more easily visualized cystoscopically due to its exophytic growth; flat carcinoma in situ is often cystoscopically invisible. This report reviews existing data concerning the prognostic value of pathologic grading and staging of non-invasive and early invasive TCC. Emphasis is placed on those studies reporting surgical treatment rather than other forms of treatment.
