Phase I study of radiochemotherapy with gemcitabine in invasive bladder cancer.

Tolerability to gemcitabine radiochemotherapy was evaluated in 33 patients with inoperable, locally advanced transitional-cell bladder cancers. The dose of 75 mg/m(2) gemcitabine once a week, concurrently with standard radiotherapy of 60 Gy/6 weeks, was found to be acceptable. Eighty-one percentage of 3-year local progression-free survival suggests efficiency warranting further studies.
