Methotrexate-paclitaxel-epirubicin-carboplatin (M-TEC) combination chemotherapy in patients with advanced bladder cancer: an open label phase II study.
The present phase II study aimed to define the application of a novel regimen incorporating methotrexate, paclitaxel, epirubicin, and carboplatin (M-TEC) in advanced bladder cancer, essentially as an M-VAC-like regimen, by substitution of cisplatin by carboplatin, doxorubicin by epirubicin and vinblastine by paclitaxel. Forty patients with advanced bladder cancer entered the study; 34 males/6 females, median age: 68 (range, 59-76), median PS (Karnovsky): 80, without receiving prior chemotherapy. Disease extention was as follows; 11/40 had local recurrence, 6/40 liver metastases, 14/40 lung metastases, bone and lymph node 8/40, bones-lymph node-lung metastases 4, lymph node and liver 4/40, lymph node-liver and lung metastases 2/40. Drug schedule and doses were as follows: paclitaxel 180 mg/m2, carboplatin AUC = 5 (according to creatinine clearance, based on Calvert's formula), and epirubicin 40 mg/m2 were administered during day 1, whereas methotrexate 30 mg/m2 and epirubicin 40 mg/m2 were administered on day 14. All patients were evaluable for response with 24/40 responding [response rate (RR) 60%]; 10/40 (25%) CR, 14/40 (35%) PR, 9/40 (22.5%) SD, and 7/40 (17.5%) PD. Symptomatic improvement was observed in 50% of patients. The median duration of response was 22 (14-32) weeks, median time-to-progression (TTP) 33 (12-44) weeks, and median survival was 56 (20-84) weeks. Toxicity was well accepted and was mainly neutropenia > grade 3: 17%, anemia >grade 3: 16%, thrombocytopenia > grade 2: 6%, nausea & vomiting mainly > grade 2: 31%, according to the administered chemotherapy cycles, whereas fatigue grade 2-3: 19%, neurotoxicity grade 1-2 13% of patients, and alopecia grade 2 was observed in all patients. The present pilot study indicates the feasibility of the M-TEC combination for bladder cancer with acceptable toxicity.
