Brief summary
Pancreatic cancer has an extremely poor prognosis with a 5-year survival rate of less than 5%. About 25% of patients have the opportunity for radically surgical resection when diagnosis. However, the recurrence rate is up to 85% within 2 years. Data from clinical trials indicated that gemcitabine-based adjuvant chemotherapy reduced recurrence and enhanced overall survival for patients who have undergone surgery to remove their tumor. Nab-paclitaxel could enhance the intratumoral concentration of gemcitabine; recent studies showed that nab-paclitaxel plus gemcitabine significantly improved progression-free survival and overall survival of metastatic pancreatic cancer patients. The present study is intended to investigate the activity and safety of the combination of gemcitabine and nab-paclitaxel as adjuvant chemotherapy in treating patients with pancreatic cancer after curative resection.
Interventions
DRUGnab-paclitaxel
Patients firstly receive nab-paclitaxel 100 mg/m\^2 (iv, 30 minutes) on days 1, 8, and 15 for 3 weeks, followed by one week without treatment. Treatment repeats every 4 weeks for up to 6 circles in the absence of disease recurrence or unacceptable toxicity.
DRUGgemcitabine
Patients secondly receive gemcitabine 1000 mg/m\^2 (iv, 30 minutes) on days 1, 8, and 15 for 3 weeks, followed by one week without treatment. Treatment repeats every 4 weeks for up to 6 circles in the absence of disease recurrence or unacceptable toxicity.

Computed tomography (CT) scan |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival after curative resection | From date of enrollment (after curative resection) until the date of death from any cause, assessed one month during therapy and 3 months thereafter up to 24 months | To evaluate the overall survival of patients (after curative resection) treated with this regimen. Outpatient visit, phone interview |
| Quality of life score after curative resection | One month during therapy and 3 months thereafter up to 24 months | To evaluate the quality of life score of patients (after curative resection) treated with this regimen. Outpatient visit, phone interview |
