Abstract

Background: The objective of this study was to evaluate the effect of a probiotic combination on the severity of oral mucositis (OM), which is a common, unpreventable complication induced by radiochemotherapy in patients with nasopharyngeal carcinoma who undergo concurrent radiochemotherapy (CCRT). Methods: Eligible patients (n = 99) with locally advanced nasopharyngeal carcinoma who were undergoing CCRT were randomly assigned (2:1) to receive a probiotic combination or placebo during radiochemotherapy, and the incidence of severe OM (grade 3 or higher) was the primary endpoint. Results: Patients taking the probiotic combination showed a significant reduction in the severity of OM. The incidences of grade 0, 1, 2, and 3 OM in the placebo group and the probiotic combination group were 0% and 12.07%, 0% and 55.17%, 54.29% and 17.24%, and 45.71% and 15.52%, respectively. Furthermore, CCRT greatly lowered the number of immune cells, whereas the probiotic combination markedly lowered the reduction rates of CD4 + T cells (76.59% vs 52.85%; P < .05), CD8 + T cells (62.94% vs 29.76%; P < .05), and CD3 + T cells (69.72% vs 45.49%; P < .05) in an A‐CCRT‐P (after treatment with radiotherapy plus chemotherapy plus the probiotic combination) group. High‐throughput sequencing results indicated that CCRT had obviously disturbed the intestinal diversity of patients in an A‐CCRT (after treatment with radiotherapy plus chemotherapy plus a placebo) group, whereas the probiotic combination distinctly restored the microbial diversity in the A‐CCRT‐P group toward that of healthy people and a B‐CCRT‐P (before the treatment of radiotherapy plus chemotherapy plus the probiotic combination) group. Conclusions: A probiotic combination significantly enhances the immune response of patients and reduces the severity of OM through modification of gut microbiota.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
