Abstract

BACKGROUND: Chemohyperthermia (C-HT) or electromotive drug administration (EMDA) are alternative therapies to radical cystectomy in patients with non-muscle-invasive bladder cancer who do not respond to intravesical therapy with bacille Calmette-Guérin. METHODS: The authors investigated a group of 87 patients with a diagnosis of high-grade non-muscle-invasive bladder carcinoma or carcinoma in situ. Of these, 45 patients received EMDA of mitomycin (EMDA/MMC) and 42 patients were treated with C-HT and mitomycin therapy (C-HT/MMC). In accordance with the Paris System for Reporting Urinary Cytology, a cytological diagnosis was made and patients with diagnoses of atypical urothelial cells (AUC), suspicious high-grade urothelial carcinoma (SHGUC), or high-grade urothelial carcinoma also underwent histological bladder biopsies. RESULTS: In accordance with the Paris System for Reporting Urinary Cytology, the AUC cases may have cytological features of SHGUC present on atypical degenerated cells. In analyzing the AUC group without the SHGUC cases diagnosed on the basis of degenerated urothelial cells, the authors found a significant association between the AUC category and a negative histological biopsy. The SHGUC group, including cases with a SHGUC diagnosis rendered on degenerated urothelial cells, was associated with high-grade urothelial carcinoma or carcinoma in situ (P= .0269 for patients treated with EMDA/MMC and P= .0049 for patients treated with C-HT/MMC). CONCLUSIONS: In the urine samples from patients treated with EMDA/MMC or C-HT/MMC, a diagnosis of SHGUC could be made even on degenerated urothelial cells when considering cellular degeneration as a "physiological" consequence of the treatment that involves either normal or neoplastic cells.
