Outcome Measures
Primary Outcomes (1)
CTCAE grade 3-4 diarrhea
Incidence of grade 3-4 diarrhea during adjuvant chemotherapy, with severity graded according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0
Throughout the entire course of adjuvant chemotherapy , up to 6 months
Secondary Outcomes (10)
Overall incidence of adverse events
Throughout the entire course of adjuvant chemotherapy , up to 6 months
rate of adjuvant treatment interruption
Throughout the entire course of adjuvant chemotherapy , up to 6 months
White blood cell count
Before the start of each cycle of adjuvant chemotherapy. A total of 6 to 8 cycles of chemotherapy are expected to be administered.
neutrophil count
Before the start of each cycle of adjuvant chemotherapy. A total of 6 to 8 cycles of chemotherapy are expected to be administered.
lymphocyte count
Before the start of each cycle of adjuvant chemotherapy. A total of 6 to 8 cycles of chemotherapy are expected to be administered.
- +5 more secondary outcomes
Study Arms (2)
intervention group
EXPERIMENTALOral administration of Clostridium butyricum capsules during adjuvant chemotherapy, 6 capsules tid. (each capsule containing ≥6.3 × 10⁶ CFU of Clostridium butyricum).
control group
PLACEBO COMPARATOROral administration of placebo capsules, 6 capsules three times daily, containing corn starch. The appearance and weight of the placebo capsules are identical to those of intervention group.

- Masking Details
- Eligible participants who meet the inclusion criteria after screening will receive either the investigational product or placebo, packaged and labeled with a unique randomization number, as assigned by an independent investigator. The participants, as well as the researchers involved in recruitment, screening, and follow-up, and the nursing staff, will all be blinded to the group assignments. Unblinding and data analysis will be conducted only after all participants have completed adjuvant chemotherapy.
