Del immune V and microbiome restructuring in colorectal cancer surgery: a randomized double blind placebo controlled trial.
Trial report in Frontiers in cellular and infection microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The gut microbiome is increasingly recognized as a central factor in carcinogenesis. Dietary components and therapeutic interventions, including probiotics, may influence microbial composition and function, thereby modulating cancer risk. Del-Immune V, a metabiotic supplement derived from Lactobacillus rhamnosus, has demonstrated immunomodulatory properties. This study investigates its role in microbiome restructuring and patient-reported outcomes in colorectal cancer patients during the perioperative period. Materials and Methods: A randomized, controlled, double-blind Phase I trial was conducted in 39 colorectal cancer patients undergoing elective resection, assigned to Del-Immune V (n=22) or placebo (n=17). Participants received two capsules daily (100 mg each), starting 7-15 days before surgery and continuing until 15 days postoperatively. Blood and fecal samples were collected at baseline and day 60 to assess IL-6, CRP, CEA, and microbiome composition. Patient-reported outcomes were measured using the EORTC QLQ-C30 questionnaire. Microbiome profiling was performed using 16S rRNA gene sequencing with PICRUSt-based functional inference. Results: Del-Immune V significantly reduced IL-6 (p=0.012) and supported CRP decline, while quality-of-life scores improved across multiple domains. Microbiome analyses revealed enrichment of short-chain fatty acid-producing genera ( Conclusions: Del-Immune V demonstrated immunomodulatory activity, evidenced by reductions in IL-6 and CRP, alongside improvements in patient-reported quality of life. These effects were accompanied by restructuring of the gut microbiome, characterized by enrichment of protective commensals and reduction of CRC-associated taxa. Collectively, findings support Del-Immune V as a safe adjunctive therapy in colorectal cancer surgery, with potential to enhance recovery and long-term outcomes.
