Feasibility of preoperative combined radiation therapy and chemotherapy with 5-fluorouracil and cisplatin in potentially resectable pancreatic adenocarcinoma: The French SFRO-FFCD 97-04 Phase II trial (original) (raw)

2006

Abstract

More than 80% of patients who undergo a potentially curative resection for pancreatic cancer develop local or distant recurrence. Neoadjuvant chemoradiotherapy might offer potential benefits regarding local and systemic control and survival. This multi-institutional Phase II trial explored the feasibility of preoperative chemoradiation in this situation. Treatment consisted of concurrent radiotherapy (50 Gy within 5 weeks), and chemotherapy with 5-fluorouracil (300 mg/m(2)/day, 5 days/week, 5 consecutive weeks) and cisplatin (20 mg/m(2)/day, Days 1-5 and 29-33), followed by surgical resection of the pancreatic tumor in patients without progression. A total of 41 patients were enrolled. Of these, 38 (93%) received > or =47 Gy; 30 patients (73%) received > or =75% of the prescribed doses of chemotherapy. Surgical resection was performed in 26 patients (63%). Because of local or metastatic progression, 5 patients (12%) did not undergo surgery and 10 underwent surgery without resection of the pancreatic tumor. Operative mortality was 2.8%. Among 40 evaluable patients, 27 were successfully treated (67.5%; 95% CI, 50.9-81.4%). Pancreatic cancer is chemo-radiosensitive. The proposed pre-operative scheme is feasible, does not prevent successful surgery, and must be tested on a Phase III setting. Yet, the large proportion of tumor progression during and after chemoradiation justifies the use of more efficient drugs such as Gemcitabine, and optimized radiotherapy including new techniques such as intensity-modulated radiation therapy.
