Brief Summary
This study is a single-arm phase II clinical trial. The study targets patients aged 18-75 years with ECOG performance status 0-2, diagnosed with locally advanced pancreatic ductal adenocarcinoma based on comprehensive assessment of pathology and imaging studies (CT or MRI). Participating patients will receive the GnP regimen every 21 days (nab-paclitaxel 125mg/m² ivgtt on days 1 and 8 + gemcitabine 1000mg/m² ivgtt on days 1 and 8, repeated every 21 days) combined with serplulimab (200mg ivgtt Q3W). In the second cycle, patients will receive SBRT targeting the primary tumor and/or retroperitoneal lymph nodes: 6.6Gy×5 fractions, 7Gy×5 fractions, or 8Gy×5 fractions, administered every other day with radiotherapy completed in 5 sessions (specific selection determined by investigators based on lesion size and organs at risk \[OAR\] assessment). Comprehensive evaluation including tumor markers and CT scans will be performed every 2 cycles with multidisciplinary team (MDT) review, and patients who meet surgical criteria will undergo radical resection surgery.
Eligibility Criteria
Inclusion Criteria: 1. Inclusion Criteria (1)Histologically confirmed pancreatic ductal adenocarcinoma with diagnosis based on comprehensive assessment of pathology and imaging studies (CT or MRI), supplemented by fibroblast activation protein positron emission tomography-computed tomography (FAPI PET-CT) when necessary, determined as locally advanced pancreatic cancer by multidisciplinary team assessment (per 2022 CSCO guideline definition) and deemed unresectable; (2)Treatment-naïve patients with no prior anticancer therapy (including chemotherapy, radiotherapy, surgery, radiofrequency ablation, irreversible electroporation, or other investigational treatments); (3)Age 18-75 years, inclusive, regardless of sex; (4)Eastern Cooperative Oncology Group (ECOG) performance status 0-2; (5)Measurable primary tumor lesions: ≥10 mm in longest diameter on spiral CT, lymph nodes ≥15 mm in short axis diameter; for conventional CT or physical examination, maximum diameter must be ≥20 mm; (6)Adequa
