Group	Intervention	Description
NASOX：Liposomal Irinotecan; Oxaliplatin; S-1	Liposomal Irinotecan	Liposomal irinotecan at a dose of 50 mg/m² is administered intravenously over 90 minutes on D1. Oxaliplatin is administered at a dose of 60 mg/m² intravenously over 2 hours on D1. S-1 at a dose of 40 to 60mg twice daily is taken orally for 7 consecutive days, followed by a 7-day break. These medications are administered once every 2 weeks for a total of 12 cycles.
GX：Gemcitabine; Capecitabine	Gemcitabine	Gemcitabine at a dose of 1000mg/m² is administered via intravenous infusion over 30 minutes on D1, 8, and 15 of a 28-day cycle. Capecitabine at a dose of 1660mg/m² per day in two divided oral doses is taken for 21 consecutive days, followed by a 7-day rest period. These medications are administered once every 4 weeks for a total of 6 cycles.

Primary Outcome Measures

Name	Time	Method
Disease-free survival (DFS)	Approximately 3 years.	Disease-free survival is defined as the time from the date of randomization to the date of disease recurrence or death from any cause (whichever occurs first). Disease recurrence is defined as evidence of disease recurrence demonstrated by imaging assessment with CT or MRI scan and/or pathological diagnosis indicated by biopsy.

Secondary Outcome Measures

Name	Time	Method
Overall survival (OS)	Approximately 5 years.
