Radiographic restaging was performed 4 to 6 weeks after chemoradiation, and patients with localized disease underwent pancreatectomy with EB-IORT. <\/jats:p><jats:p> RESULTS: Thirty-five patients completed chemoradiation; 16 (46%) experienced grade 3 toxicity. Four patients (11%) required hospitalization for dehydration due to grade 3 nausea and vomiting. Twenty (80%) of 25 patients who underwent surgery underwent pancreatectomy; EB-IORT was used in 13 patients. There were no histologic complete responses to preoperative therapy; 21% of specimens demonstrated more than 50% nonviable cells (grade 2b treatment effect). With a median follow-up period of 46 months, the 3-year overall survival rate with chemoradiation and pancreatectomy was 28%. <\/jats:p><jats:p> CONCLUSION: Preoperative paclitaxel-based concurrent chemoradiation is feasible. The toxicity of this regimen seems greater than that with fluorouracil. The histologic responses and survival are similar, suggesting no advantages to paclitaxel-based preoperative treatment. <\/jats:p>","DOI":"10.1200\/jco.2002.11.064","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:13:48Z","timestamp":1027775628000},"page":"2537-2544","source":"Crossref","is-referenced-by-count":161,"title":["Preoperative Paclitaxel and Concurrent Rapid-Fractionation Radiation for Resectable Pancreatic Adenocarcinoma: Toxicities, Histologic Response Rates, and Event-Free Outcome"],"prefix":"10.1200","volume":"20","author":[{"given":"Peter W.","family":"T.
