Abstract
Aims and Background
Urothelial cancer is a chemosensitive disease. However, cisplatin or anthracycline-containing regimens still provoke severe toxicity mainly due to reduced renal function and poor performance status (PS) of patients. The aim of this study was to verify the possibility of substituting carboplatin for cisplatin and epirublcin for doxorubicin in the M-VAC regimen in order to reduce toxicity and improve patient tolerance.
Methods
Twenty patients with advanced urothelial tract tumors were treated with a chemotherapeutic regimen composed of methotrexate (30 mg/mq iv on days 1, 15, 22), vinblastine (3 mg/m2 iv on days 2, 15, 22), epidoxorubicin (35 mg/m2 iv on day 2) and carboplatin (250 mg/m2 iv on day 2) every four weeks (M-VECA). All patients had bidimensionally measurable disease.
Results
Of the 18 evaluable patients, 3 (17 %) obtained complete response and 7 (33 %) obtained partial response (50 % overall response). The median duration of response was 50 weeks (range, 28-88+). Grade III-IV toxicity (leukothrombocytopenia and mucositis) was observed in 20 % of cases. Nevertheless, recovery was prompt in all but 2 patients with poor PS who died of nadir sepsis.
Conclusions
M-VECA was an effective regimen for the treatment of patients with metastatic urothelial tumors and was safely employed in patients with a good PS. However, the possibility of substituting carboplatin for cisplatin as neoadjuvant therapy for less advanced stages needs further investigation in randomized studies.
