4. Locally advanced lesions meeting any of the following criteria without distant metastasis: ① Pancreatic head and neck tumors: a. The tumor invaded the Superior Mesenteric Artery (SMA) more than 180°; b. The tumor invaded the celiac trunk more than 180°; c. Unresectable reconstruction of superior mesenteric vein or portal vein due to tumor invasion or embolism (tumor thrombus or thrombus); d.

The tumor invaded the superior mesenteric artery or celiac trunk more than 180°; b. Celiac trunk and abdominal aorta involvement; c. The superior mesenteric vein or portal vein cannot be resected and reconstructed due to tumor invasion or embolism (tumor thrombus or thrombus).
5. At least one measurable lesion according to revised RECIST version 1.1;
6. ECOG score 0-1;
7. Be able to receive gemcitabine for injection and paclitaxel for injection (albumin-bound) combined therapy according to medical advice;
8. Able to operate tumor treating fields independently or with the help of nursing staff;
9. AE should be restored to normal or CTCAE1 grade after previous treatment;
10. The serum pregnancy test results of female subjects of reproductive age were negative. Female subjects of reproductive age agree to use effective contraception (e.g. hormonal or barrier methods or abstinence) during the study period and for 6 months after the last dose of chemotherapy drugs;
11. Male subjects agree to use effective birth control (such as barrier method or abstinence) and not to donate sperm during the study and within 3 months after the last chemotherapy drug administration;
12. Voluntarily sign the informed consent.

Exclusion Criteria:

1. The subjects has previously received first-line treatment for pancreatic adenocarcinoma;
