From 1998 to 2010, 86 patients with pancreatic adenocarcinoma who underwent resection were treated with adjuvant concurrent chemoradiation. Thirty-four patients received concurrent 5-fluorouracil-based chemoradiation (5-FU/RT) with traditional field radiation (range, 45-61.2 Gy; median, 50.4 Gy) without further adjuvant therapy. Thirty patients received traditional field 5-FU/RT (range, 45-60.4 Gy; median, 50.4 Gy) with Gem (1,000 mg/m2 weekly) either before and after radiotherapy or only after radiotherapy. Twenty-two patients received concurrent full-dose Gem (1,000 mg/m2 weekly)-based chemoradiation (Gem/RT), consisting of involved-field radiation (range, 27-38 Gy; median, 36 Gy) followed by further adjuvant Gem.
The median age of the cohort was 65 years (range, 40-80 years). Of the patients, 58 had T3 tumors (67%), 22 had T2 tumors (26%), and 6 had T1 tumors (7%). N1 disease was present in 61 patients (71%), whereas 18 patients (21%) had R1 resections. Performance status, lymph node status, and margin status were all similar among the treatment groups. Median follow-up was 19.0 months. Median overall survival (OS) (19.2 months, 19.0 months, and 21.0 months) and 3-year OS rates (26.5%, 27.2%, and 32.1%) were similar among patients with 5-FU/RT with no adjuvant Gem, those with 5-FU/RT with adjuvant Gem, and those with Gem/RT with adjuvant Gem, respectively (
In our cohort of patients with resected pancreatic cancer, Gem chemotherapy did not improve OS after chemoradiotherapy.
