Eight years of experience with preoperative angiographic and lymphographic staging of bladder cancer.

Abstract

Our experience with the preoperative staging of bladder cancer by bilateral selective hypogastric arteriography has been accumulated since 1968. More than 150 patients have been studied by selective angiography before radical cystectomy. Our latest series of 52 patients (1972 to 1976) compares to our previous experience demonstrating angiographic staging accuracy to detect bladder invasion and occult metastases at a rate exceeding that of clinical staging alone. Arteriographic staging of D lesions, when supplemented with lymphography, approaches 100 per cent accuracy. Falsely negative lymphograms currently are extremely uncommon (1.9 per cent). In several illustrated instances angiographic staging was proved to be even more accurate than the pathologic staging of a limited cystectomy specimen. The over-all angiographic and lymphangiographic staging accuracy in our most recent series of cystectomy patients was 78.8 per cent. The techniques and reliability of the data are discussed in detail, including the factors that interfere with the exact arteriographic staging of bladder cancer. However, these factors are more troublesome in early stage lesions. These studies demonstrate the role and value as well as areas of limitation of preoperative arteriography and lymphography in the evaluation of invasive bladder cancer.
