Nab-Paclitaxel and Gemcitabine Plus Camrelizumab and Radiotherapy for Locally Advanced Pancreatic Adenocarcinoma

Nab-Paclitaxel and Gemcitabine Plus Camrelizumab and Radiotherapy Versus Nab-Paclitaxel and Gemcitabine Alone for Locally Advanced Pancreatic Adenocarcinoma

The study is a prospective and observational cohort study. The purpose is to to investigate the safety and efficacy of nab-paclitaxel and gemcitabine plus camrelizumab and radiotherapy versus nab-paclitaxel and gemcitabine alone for locally advanced pancreatic adenocarcinoma (PDAC)

We will prospectively collect 100 patients who receive nab-paclitaxel and gemcitabine plus camrelizumab and radiotherapy or nab-paclitaxel and gemcitabine alone. Data will be stored in a private database. The process of data collection will be supervised and regular data examination will be performed.

Inclusion Criteria:

1. aged 18-75 years;

2. histologically or cytologically proven diagnosis of pancreatic adenocarcinoma;

3. treatment-naive locally advanced pancreatic cancer (locally advanced status was determined by our multidisciplinary team based on the National Comprehensive Cancer Network definitions);

4. no distant metastasis as defined by CT or MRI of the chest, abdomen and pelvis;

5. at least 1 measurable lesion based on the Response Evaluation Criteria in Solid Tumors criteria (RECIST) 1.1;

6. an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 1;

7. adequate hematological, liver, renal function:

   1. absolute neutrophil count≥1500 cell/mm3;
   2. platelet count≥100×109/L;
   3. hemoglobin concentration >90 g/L;
   4. albumin≥30 g/L ;
   5. total bilirubin<1.5 times the upper limit of normal;
   6. alanine aminotransferase and aspartate aminotransferase≤3 times the upper limit of normal;
   7. serum creatinine concentration<1.5 times the upper limit of the normal range or less and creatinine clearance rate≥45 mL/min;

8. life expectancy of at least 3 months.

Exclusion Criteria:

1. with any other malignancy within the 5 years before enrolment;
2. with active infections (bacterial, viral, or fungal) requiring systematic treatment, with hepatitis B or C infection, or a history of HIV infection, or receiving immunosuppressive therapy;
