Purpose: To evaluate the IO-year outcome of patients with invasive (T2-3N0M0, staged according to the tumor, node, metastasis system) bladder cancer who responded completely to a combination of methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) chemotherapy followed by bladder-sparing surgery, Patients and Methods: Of 111 surgical candidates who received neoadjuvant MVAC, 60 (54%) achieved a complete clinical response (TO) on transurethral resection (TUR) of the primary tumor site, Of these, 28 requested follow-up with TUR alone, 15 had a partial cystectomy, and 17 elected a radical cystectomy. The patients were followed up for a median of 10 years (range, 8 to 13 years). Results: Of 43 patients who had bladder-sparing surgery, 32 (74%) are alive, which includes 25 (58%) with an intact functioning bladder, Twenty-four patients (56%) developed bladder tumor recurrences from 5 to 96 months, which were invasive in 13 (30%) and superficial in 11 (26%), Thirteen patients required a salvage cystectomy, of whom 6 died, which includes 4 (9%) from a new invasive neoplasm, Of the 17 patients who had radical cystectomy, 11 (65%) are alive, Conclusion: The majority of patients with invasive bladder tumors who achieve TO status after neoadjuvant MVAC chemotherapy preserve their bladders for up to 10 years with bladder-sparing surgery, The bladder remains at risk for new invasive tumors, Cystectomy salvages the majority, but not all, of relapsing patients.
