ARTICLE HIGHLIGHTS
Research background
Nab-paclitaxel plus gemcitabine (AG) has resulted in better tumor response and survival rates for metastatic or advanced pancreatic ductal adenocarcinoma (PDAC) compared with gemcitabine (GEM) alone. However, its role in adjuvant therapy for resected PDAC remains unclear.
Research motivation
This study aimed to examine the effects of AG and GEM alone as adjuvant therapy for resected PDAC.
Research objectives
This study examined the safety and efficacy of AG adjuvant therapy for resected PDAC.
Research methods
We retrospectively reviewed our PDAC database for patients with primary resectable PDAC who were treated with AG or GEM alone as postoperative adjuvant chemotherapy between January 2013 and December 2016.
Research results
The median follow-up duration was 22 mo in the GEM group and 27 mo in the AG group. Compared with GEM, median disease-free survival (12.2 mo vs 15.8 mo, P = 0.039) and overall survival (20.6 mo vs 28.3 mo, P = 0.028) were significantly improved in the AG group. The 2-year overall survival rates were 63.3% and 43.3% in the AG and GEM groups, respectively. However, the incidence of sensory neuropathy was significantly higher in the AG than in the GEM group (53.3% vs 23.3%, P < 0.001).
Research conclusions
This study suggested that AG significantly improved disease-free survival and overall survival of patients with resected PDAC. AG may be a potential option for postoperative adjuvant chemotherapy of resectable PDAC.
Research perspectives
The present study had several limitations due to its retrospective study design. It was also a single-center, nonrandomized controlled study with potential selection bias. However, our results initially indicated the efficacy and safety of AG for resectable PDAC. The ongoing Phase III APACT study is investigating survival for adjuvant GEM compared with AG for resected PDAC. We look forward to seeing the results of this study that are expected by 2022.
