Purpose: The purpose of this guideline update is to incorporate recently reported practice-changing evidence into ASCO's recommendations on potentially curable pancreatic adenocarcinoma.
Methods: ASCO convened an Expert Panel to evaluate data from PRODIGE 24/CCTG PA.6, a phase III, multicenter, randomized clinical trial of postoperative leucovorin calcium, fluorouracil, irinotecan hydrochloride, and oxaliplatin (FOLFIRINOX) versus gemcitabine alone, presented at the 2018 ASCO Annual Meeting. In addition, PubMed was searched for additional papers that may influence the existing recommendations.
Recommendations: The Expert Panel only updated Recommendation 4.1 as a result of the practice-changing data. Recommendation 4.1 states that all patients with resected pancreatic adenocarcinoma who did not receive preoperative therapy should be offered 6 months of adjuvant chemotherapy in the absence of medical or surgical contraindications. The modified combination regimen of 5-fluorouracil, oxaliplatin, and irinotecan (mFOLFIRINOX; oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, irinotecan 150 mg/m2 D1, and 5-fluorouracil 2.4 g/m2 over 46 hours every 14 days for 12 cycles) is now preferred in the absence of concerns for toxicity or tolerance; alternatively, doublet therapy with gemcitabine and capecitabine or monotherapy with gemcitabine alone or fluorouracil plus folinic acid alone can be offered.Additional information can be found at www.asco.org/gastrointestinal-cancer-guidelines.
