- Control Group
- description
- Patients in the control group continued their original chemotherapy/targeted therapy regimen, with each treatment cycle lasting 3 weeks, for a total of 5 cycles. Treatment efficacy was assessed after every 2 cycles.

- Experimental Group
- description
- Patients in the FMT group received treatment starting from the fourth cycle on top of their existing regimen. They underwent one FMT treatment within 3 days prior to chemotherapy/targeted therapy during the fourth, sixth, and eighth cycles (weeks 3, 9, and 15 after study initiation). Each transplant consisted of approximately 40g of donor gut microbiota encapsulated in capsules. The capsules were administered orally, typically at a dose of 2-3 capsules (1g/capsule) every 3-5 minutes, totaling 40 capsules per dose for a total of 120 capsules. Treatment cycles were conducted every 3 weeks, with therapeutic efficacy assessed after every 2 cycles.
