What this trial studies

This clinical trial investigates the impact of the probiotic L. plantarum 299v on gut microbiome health, diarrhea, and Clostridioides difficile infection in colorectal cancer patients undergoing surgery. A total of 60 participants will be divided into four groups, with some receiving the probiotic, others receiving a combination of the probiotic and inulin, while control groups will receive placebos. The study aims to assess the efficacy of these interventions over a four-week period. Participants will be monitored for gastrointestinal health and infection rates.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with colorectal cancer who are preparing for surgical treatment.

Not a fit: Patients with other cancers, inflammatory bowel diseases, or those who have recently taken certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve gut health and reduce the incidence of diarrhea and infections in colorectal cancer patients.

How similar studies have performed: Previous studies have shown promising results with probiotics in managing gut health, suggesting potential success for this approach.
