Purpose
Gemcitabine and nab-paclitaxel (GnP) combination therapy is a standard regimen for advanced pancreatic ductal adenocarcinoma (PDAC) worldwide; however, concerns regarding the unexpectedly high incidence of interstitial lung disease (ILD) have emerged. We investigated the incidence and predictive factors of ILD in PDAC patients who were treated with GnP combination therapy.
Methods
Thirty-seven patients treated with GnP therapy as either 1st or 2nd line treatment were included, among whom seven developed ILD (18.9%). The clinical characteristics (age, etc.) were compared between patients with and without ILD. The diagnostic yield of the markers to predict the presence of ILD was calculated. The clinical course of the seven patients with ILD was summarized. Survival analysis was performed using the Kaplan–Meier method and log-rank test.
Results
The median age was higher in patients with ILD (73.0 vs. 65.0 years old, p = 0.03), while no differences were observed in the other clinical characteristics. Among the three investigated markers, SP-D showed the best diagnostic yield (AUC = 0.94) for diagnosing ILD. Though one patient required steroid therapy and the discontinuation of GnP therapy, all patients could undergo subsequent treatment. In the survival analysis, the median survival time of PDAC patients with ILD was comparable to that of patients without ILD (25.1 vs. 24.5 months, p = 0.98).
Conclusion
ILD was observed in 18.9% of PDAC patients treated with GnP therapy. With appropriate management, no prognostic influence was observed.
