Brief Summary

The goal of this interventional study is to learn about the clinical efficacy of sequential therapy (albumin paclitaxel, gemcitabine combined with PD-L1 antibodies, followed by liposomal irinotecan, oxaliplatin and 5-FU/LV combined with PD-L1 antibodies). The main questions it aims to answer are:

Does the sequential therapy increase the resection rate of borderline resectable / locally advanced pancreatic cancer? Does the sequential therapy represent an effective and safe treatment? Participants will receive two distinct chemotherapy regimens, each combined with a PD-L1 antibody, administered in sequence for two cycles each.

Study Groups

Sequential therapy

Group Type: EXPERIMENTAL

Treatment: AG & anti-PD-L1 + FOLFIRINOX & anti-PD-L1

Intervention Type: DRUG

The cohort A (borderline resectable) and cohort B (locally advanced) both received treatment with gemcitabine, albumin paclitaxel (administered on days 1, 8, and 15, with 4 weeks as one cycle) and adalimumab (administered once every 4 weeks, with 4 weeks as one cycle). After completing 2 cycles of treatment, they were sequentially given liposomal irinotecan combined with 5-FU/LV, oxaliplatin (administered once every 2 weeks, with 4 weeks as one cycle) and adalimumab (administered once every 4 weeks, with 4 weeks as one cycle). After completing 2 cycles of sequential treatment, surgical evaluation was conducted: for patients who could undergo radical surgical resection, surgery was performed within 2-4 weeks after the end of the conversion treatment stage, and the postoperative treatment plan was selected based on the investigator's judgment; for patients who could not undergo radical surgical resection, subsequent treatment plans could be selected based on the investigator's judgment.

Eligibility Criteria

Inclusion Criteria

• Age ≥ 18 years old, gender not restricted
• According to the NCCN Clinical Practice Guidelines for Pancreatic Cancer (2024.V2 version), patients with borderline resectable/locally advanced pancreatic cancer as evaluated by multidisciplinary and imaging assessment, the definition of borderline resectability includes:

1. No distant metastasis;

2. Arteries: 1. Pancreatic head/neck: The tumor is in contact with the common hepatic artery and does not extend to the abdominal aorta or the hepatic artery bifurcation, and can be safely resected and reconstructed; the tumor is in contact with the superior mesenteric artery ≤ 180°; the tumor contacts variant arteries (such as the accessory right hepatic artery, replacement of the hepatic right artery, replacement of the common hepatic artery or the starting part of the accessory/secondary artery, etc.), but can be safely resected and reconstructed. 2. Pancreatic body/tail: The tumor is in contact with the abdominal aorta ≤ 180°;

3. Veins: The tumor is in contact with the superior mesenteric vein or portal vein > 180°, or contact ≤ 180° combined with irregular venous contour or venous thrombosis, and there are appropriate blood vessels at the proximal and distal ends of the affected area that can be completely resected and reconstructed; the tumor contacts the inferior vena cava;

Local advanced pancreatic cancer is defined as:

<!-- -->

1. No distant metastasis;

2. Arteries: 1. Pancreatic head/neck: The tumor is in contact with the superior mesenteric artery or the celiac trunk artery > 180°; 2. Pancreatic body/tail: The tumor is in contact with the superior mesenteric artery or the celiac trunk artery > 180°; the tumor contacts the celiac trunk artery and invades the abdominal aorta;

3. Veins: Due to tumor invasion, vein occlusion or involvement of a large area of the superior mesenteric vein and ileal branch, it is impossible to safely reconstruct the portal vein - superior mesenteric vein;

• No previous anti-tumor treatment (including radiotherapy, ablation, chemotherapy, targeted therapy, immunotherapy, etc.), investigational drug treatment;
• Must have at least one measurable lesion as the target lesion (according to RECIST v1.1 standard);
• ECOG: 0 - 1
• Expected survival ≥ 3 months;
• Good function of major organs, that is, in accordance with the following standards (within 14 days before randomization, no blood components, cell growth factors were received):

1. Neutrophils ≥ 1.5 * 10^9/L; platelets ≥ 80 * 10^9/L; hemoglobin ≥ 9 g/dl; serum albumin ≥ 3 g/dl;

2. Total bilirubin ≤ 1.5 times the upper limit of normal (biliary obstruction allows biliary drainage); ALT and AST ≤ 3 times the upper limit of normal;

3. Serum creatinine ≤ 1.5 times the upper limit of normal, creatinine clearance rate ≥ 60 ml/min;

4. INR ≤ 1.5 times the upper limit of normal and APTT ≤ 1.5 times the upper limit of normal (for those using stable doses of anticoagulation therapy such as low molecular weight heparin or warfarin and INR within the expected treatment range of the anticoagulant can be screened);

5. Electrocardiogram: QTcF ≤ 450 ms (male), ≤ 470 ms (female);

6. Cardiac echocardiography: LVEF (left ventricular ejection fraction) ≥ 50%;
