Perioperative Chemotherapy and Chemoradiotherapy for Patients With Resectable and Borderline Resectable Pancreatic Adenocarcinoma

ObjectivesPancreatic ductal adenocarcinoma (PDA) is the third most common cause of cancer death in the United States. Most patients who undergo resection develop recurrence. Standard treatment confers a median overall survival (OS) of 24 months. Exposure to alternate regimens may prevent chemoresistance. This study evaluated multiagent perioperative therapy for potentially resectable PDA patients to improve OS.MethodsA single center, phase 2, trial of patients with resectable or borderline resectable PDA. Patients received neoadjuvant therapy with induction chemotherapy (gemcitabine, docetaxel, capecitabine) for 3 cycles, chemoradiation (intensity-modulated radiation therapy with capecitabine and oxaliplatin) followed by surgery, and 2 months of adjuvant gemcitabine and oxaliplatin and 2 months of gemcitabine. The primary endpoint was OS. The secondary endpoint was recurrence-free survival (RFS).ResultsThirty-two eligible patients were enrolled. Twenty-two patients underwent surgical resection. After a median follow-up of 56.8 months, mOS was 31.6 months (95% confidence interval [CI], 14.2-58.1) for all patients, 58.1 months (95% CI, 31.6 to NR) for those who completed surgery. The mRFS was 31.3 months (95% CI, 12.5 to NR).ConclusionsPerioperative therapy with GTX, chemoradiotherapy, and adjuvant GemOx/Gem resulted in promising survival of 58 months for patients who underwent resection and may represent another treatment option for PDA.

Automated summary

This study evaluated the effect of multiagent perioperative therapy on overall survival in potentially resectable pancreatic ductal adenocarcinoma (PDA) patients. The results showed a promising survival of 58 months for patients who underwent surgical resection, which may represent another treatment option for PDA.
