Brief summary
The study is to evaluate the R0 resection rate of patients with unresectable locally advanced pancreatic cancer ,after treated with S-1 plus Paclitaxel-albumin as neoadjuvant chemotherapy protocols
Detailed description
BACKGROUND: 1. The incidence of pancreatic cancer in China has been increasing rapidly in recent years，but most of the pancreatic cancer patients are unresectable, whose median survival time were only 6\ 9 months. 2. Studies have shown that neoadjuvant therapy improves the quality of surgery in patients with pancreatic cancer，and prolong their life. 3. S-1 is a new generation of oral fluorouracil derivatives ,S-1 single drug as an adjuvant therapy for resectable pancreatic cancer is better than gemcitabine, and has less side effects than gemcitabine. Protein bound paclitaxel is a novel paclitaxel combined of paclitaxel and albumin by nanotechnology , which can extend free survival in patients with advanced pancreatic cancer with less side effects than gemcitabine. So S-1 combined with Paclitaxel-albumin is expected to play an important role in neoadjuvant chemotherapy in Pancreatic cancer, and may improve the rate of R0 resection in patients with unresectable locally advanced pancreatic. STUDY DESIGN: S-1 combined with Paclitaxel-albumin 1. S-1:40\ 60mg bid, day 1\ 14 (S-1: BSA (Body surface area)\<1.25m2, 40mg bid , 1.25m2 ≤ BSA ≤1.5m2, 50mg bid, BSA\>1.5m2, 60mg bid),2 weeks and rest for 1 weeks. 2. Paclitaxel-albumin: 125 mg/m2, intravenous infusion for 30 minutes, Day1 and Day 8. Repeat every three weeks. for 6 cycles.

Exclusion criteria
1. Woman in pregnant or lactation period 2. Woman of childbearing age who was positive at baseline pregnancy test or did not have pregnancy tests.Menopausal women must have menopause for at least 12 months before they think they are free of pregnancy. 3.

Patients with upper gastrointestinal obstruction or Abnormal physiological function or Malabsorption syndrome, which may affect the absorption of S-1. 8.

Patient that is lack of dihydropyrimidine dehydrogenase (DPD) 11. Allergic to any of the drug ingredients in this study 12. participate in other clinical trials within 4 weeks before randomization -
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| R0 resection rate | one week After the operation | Evaluate the R0 resection rate of S-1 combined with Paclitaxel-albumin as neoadjuvant chemotherapy in patients with unresectable locally advanced pancreatic cancer |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The objective remission rate (ORR) | at the end of cycle 6 of the neoadjuvant chemotherapy((each cycle is 21 days) | Evaluate the objective remission rate (ORR) of S-1 combined with Paclitaxel-albumin as neoadjuvant chemotherapy in patients with unresectable locally advanced pancreatic cancer |
| The disease free survival (DFS) | From date of randomization until the date of first documented progression or date of death from any cause, whichever came first,assessed up to 60 months. Progressing should be confirmed by imaging examination or histology / cytology examination. | Evaluate the disease free survival (DFS) of S-1 combined with Paclitaxel-albumin as neoadjuvant chemotherapy in patients with unresectable locally advanced pancreatic cancer |
| The 2 year and 5 year survival rate | 2 years and 5 years after treatment | Evaluate the 2 year and 5 year survival rate of S-1 combined with Paclitaxel-albumin as neoadjuvant chemotherapy in patients with unresectable locally advanced pancreatic cancer |
| The quality of life | Questionnaire at baseline, and then 1-2 days before each cycle of treatment(each cycle is 21 days, for a total of 6 cycles.). During follow-up period after treatment, questionnaire every 6 months, up to 2 years. | Assess the quality of life in pancreatic cancer according to EORTC QLQ-PAN26(European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Pancreas 26).For each assessment item, there are four options, scores are as 1,2,3,4. Each score corresponds to a physical condition. Then have the total score for each patient. The total score range from 26-104, the higher the score, the poorer the quality of life is. |
