ABSTRACT
Background & objectives: Gemcitabine combined with non-cremophor-based paclitaxel is one of the standards of care in advanced inoperable pancreatic cancer. This study was undertaken to retrospectively evaluate real world non-trial outcomes with this combination. Methods: Patients with histologically proven advanced inoperable pancreatic adenocarcinoma (PDAC), treated with non-cremophor-based paclitaxel-gemcitabine combination (PG) (gemcitabine-nanoxel or gemcitabine-abraxane) between January 2012 and June 2015, were retrospectively analyzed. Response assessment was done every 8-12 wk with computed tomography scan and responses were measured as per the Response Evaluation Criteria in Solid Tumours 1.1 criteria where feasible. Toxicity was recorded as per the Common Terminology Criteria for Adverse Events (CTCAE) v4 criteria. Progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Results: A total of 78 patients with PDAC were treated with the combination. Of these, 83.3 per cent of patients had metastatic disease. The median number of chemotherapy cycles administered was three. The objective response rate for the whole group was 30.8 per cent. Grade III/IV toxicities were seen in 35.9 per cent of patients. Median PFS was 5.6 months and median OS was 11.6 months. Interpretation & conclusions: Non-cremophor-based paclitaxel in combination with gemcitabine appeared efficacious for advanced pancreatic cancers in routine clinical practice. Within the confines of a single-centre retrospective analysis, gemcitabine-nanoxel and gemcitabine-abraxane appeared to have similar efficacy and toxicity in advanced pancreatic cancers.
