Resumen


Background: patients with cervical cancer (CC) receiving chemotherapy and radiotherapy have several gastrointestinal adverse effects.

Objective: to evaluate the effect of dietary symbiotic supplementation on fecal calprotectin (FCP), bacterial DNA levels, and gastrointestinal adverse effects in patients with CC.

Methods: clinical, controlled, randomized, double-blind trial. Patients consumed symbiotics or placebo three times a day for seven weeks. FCP was assessed by Elisa method. DNA from probiotic and pathogenic bacteria were determined by quantitative real-time polymerase chain reaction. Diarrheal evacuations were evaluated with the Bristol stool form scale and nausea and vomiting were measured using the scale of the National Institute of Cancerology of the United States.

Results: after a seven-week treatment, FCP concentration was lower in the symbiotic group compared to the control group (p < 0.001). Stool consistency in the placebo and symbiotic groups was similar at baseline. A significant improvement in stool consistency was obtained in both groups at the end of the intervention (p < 0.001). The concentrations and total proportions of the probiotic and pathogenic bacteria were similar in both groups. Nausea significantly diminished in both groups (p < 0.001) at the end of the trial. Furthermore, the symbiotic group had a statistically significant decrease in the frequency and intensity of vomiting when compared to the control group (p < 0.001).

Conclusions: the symbiotic treatment decreases significantly the FCP levels and the frequency and intensity of vomiting in patients with CC.
