Pancreatic Ductal Adenocarcinoma Clinical Trial
Official title:
Synergistic Immunomodulatory Effect of Synbiotics Pre and Postoperative Resection of Pancreatic Ductal Adenocarcinoma
The goal of this interventional study was to evaluate the synergistic effect of symbiotics (a combination of probiotics and prebiotics) compared to probiotics alone in terms of their impact on anti-tumor immunomodulation in patients with pancreatic ductal adenocarcinoma (PDAC). The study also aimed to assess the effects of these interventions on postoperative complications and outcomes. In the study, a probiotic agent (Nowfoods, USA), containing ten strains of bacteria with a total dosage of 25 billion colony-forming units (CFU) was administered. This probiotic regimen involved taking two capsules once daily, starting two weeks before the surgery and continuing for one month after the surgery. For the synbiotic group, in addition to the probiotic agent, two capsules per day of inulin supplement (HERBAMAMA, USA) were also taken. The study included three groups: the synbiotics group, the probiotics group, and the placebo group. The researchers compared the pathological status of immune cell infiltration (specifically CD8 cells) and interferon-gamma expression, as well as the levels of interleukins 10, 6, and 10 in the participants' serum. Four blood samples were collected from each participant: one taken 14 days before the surgery, one on the surgery date, one two weeks after the surgery, and one 30 days after the surgery. The main research question addressed by the study was whether there was a significant difference in the immunomodulatory effect and postoperative complications between the synbiotics group and the probiotics group. The placebo group likely served as a control to compare the effects of the interventions against no intervention.
