A new regimen of cisplatin, epirubicin and methotrexate (PEM-3) as primary chemotherapy for locally advanced bladder cancer.
In this phase II study, 41 patients with locally advanced urothelial bladder cancer (T2-4, N0, M0) were treated with primary chemotherapy (cisplatin, epirubicin, methotrexate: PEM-3). All the patients were assessable for response and toxicity. Clinical monitoring was performed with computerized tomography and cystoscopy. Nineteen clinical complete remissions (46%) and 10 partial remissions (24.5%) were obtained (CR + PR, 70.5%; 95% confidence interval, 57%-85%). Ten patients were considered to have clinically stable disease (24.5%), and 2 patients progressed (5%). Surgery after chemotherapy was performed in 22 cases: in 6 patients (27%) a pathologic complete response was achieved. The pathologic stage was lower than the initial clinical stage in 13 patients (59%). After a median follow-up of 3 years (range, 1-4), the median time to progression was 104 weeks. At this writing, 20 patients, 12 of which were submitted to surgery and 8 were not operated, are disease-free. The 3-year survival rate is 52%. No one had to interrupt the treatment because of toxicity. In conclusion, the PEM-3 regimen is a very active and well-tolerated regimen in locally advanced bladder cancer.
