Resumen
Fecha de inicio: 1 de mayo de 2001
Fecha en la que se inscribió al primer participante.OBJECTIVES: Primary * Compare the survival of patients with locally or regionally advanced unresectable adenocarcinoma of the pancreas treated with fluorouracil, external beam radiotherapy, and gemcitabine with vs without brachytherapy with phosphorus P32 suspension. Secondary * Compare time to disease progression, tumor response rate, and physical performance in patients treated with these regimens. * Compare the safety and tolerability of these regimens in this patient population. * Compare duration of response and time to treatment failure in patients treated with these regimens. OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive phosphorus P32 suspension percutaneously under CT guidance on day 0 and at months 1, 2, 6, 7, and 8. Patients receive fluorouracil IV continuously on days 1-5 of weeks 1-6. Patients concurrently undergo external beam radiotherapy 5 days a week on weeks 1-6. At the completion of radiotherapy, patients receive gemcitabine IV over 30 minutes once weekly for 7 weeks. After a 1-week rest, patients then receive gemcitabine IV over 30 minutes once weekly for 3 weeks. Treatment repeats every 28 days. * Arm II: Patients receive fluorouracil and gemcitabine and undergo external beam radiotherapy as in arm I. In both arms, treatment continues in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months. PROJECTED ACCRUAL: A total of 80 patients (40 per treatment arm) will be accrued for this study within 24-30 months.
