Summary

To explore the clinical characteristics of pancreatic cancer patients with liver metastases who can benefit from surgery, and to develop evaluation criteria for surgical indications, so as to provide basis for comprehensive treatment strategies for advanced pancreatic cancer patients.

Detailed description

Initial Systemic Treatment: Subjects who meet the inclusion criteria will first undergo systemic treatment. The primary treatment regimens will follow the NCCN guideline-recommended first-line chemotherapy options, including the AG regimen, FOLFIRINOX regimen, and the NALIRIFOX regimen. Periodic Assessments: Every 4 treatment cycles, laboratory tests (including blood routine, coagulation function, liver and kidney function, and tumor markers) and imaging studies (enhanced CT or MRI, with PET-CT if necessary) will be conducted. After 4-6 cycles, imaging and tumor marker assessments will be performed to evaluate the patient's disease status. A multidisciplinary discussion will determine if patients with a good response to systemic treatment are eligible for radical surgery. Treatment Adjustment and Surgical Intervention: For patients assessed as having disease progression during the first evaluation, the treatment plan will be adjusted, and assessments will be conducted every 2 cycles. Patients showing a good response may still be considered for radical surgery. For pancreatic lesions, surgical procedures such as pancreaticoduodenectomy or distal pancreatectomy with splenectomy will be performed based on the lesion's location, with total pancreatectomy considered if necessary. For liver lesions, the surgical approach will depend on the number, size, and location of the lesions. During surgery, tumor and adjacent tissue samples (approximately 100mg, the size of a soybean) will be collected for research purposes, provided it does not affect diagnosis. Postoperative discarded specimens (approximately 500mg) will also be collected and preserved. Postoperative Monitoring: Laboratory tests, including but not limited to blood routine, coagulation, liver, kidney, and pancreatic function, will be collected on postoperative days 1, 3, 5, 7, and 30. Adjuvant Treatment and Complication Monitoring: Postoperative adjuvant treatment will continue according to the original regimen. Any postoperative complications and adverse reactions during chemotherapy will be recorded. Trial Progress Tracking: The progress of each subject will be documented. If a subject withdraws or drops out, the reason and the date of the last medication will be recorded. Follow-Up: After the completion of treatment, patients will be followed up monthly until death.
