This single arm, open labeled, non randomized study was aimed to evaluate the toxicity of 3 cycles of MVAC (methotrexate, vinblastine, doxorubicin and cisplatin) with rhG-CSF (5 micrograms/kg/day from day 3 to day 14), on 14 patients with previously untreated infiltrating bladder carcinoma, 42 cycles were administered. Chemotherapy toxicity was very low, with 7% of neutropenia grade 3 or 4.4% of thrombocytopenia grade 2, no mucositis above grade 2 and no nadir sepsis. Bone pain related to rhG-CSF occurred in 14% of cycles. 88% of the cycles were given at full dose without any delay and mean relative dose intensity was 96.4% (RDI was 100% for 9 patients). One patient achieved a complete pathological response (cystectomy: 1) and 6 clinical responses with negative transurethral resection. Addition of rhG-CSF to MVAC chemotherapy allows a high dose intensity of MVAC with very low toxicity over 3 cycles. This association should be compared to standard MVAC or intensified regimens to evaluate efficacy, toxicity, and cost effectiveness.
