The meta-analysis on abundance changes of bacteria genera was performed via a random-effects model.\u003Cbr>Results: A total of 18 studies involving 1056 participants were included. They consisted of two categories of studies: 1) case-control studies (n = 9); 2) nine studies that compared the oral microbiome between cancerous tissues and paired paracancerous tissues. At the phylum level, enrichment of Fusobacteria but depletion in Actinobacteria and Firmicutes in the oral microbiome was demonstrated in both categories of studies. At the genus level, Fusobacterium showed an increased abundance in OSCC patients (SMD = 0.65, 95% CI: 0.43–0.87, Z = 5.809, P = 0.000) and in cancerous tissues (SMD = 0.54, 95% CI: 0.36–0.72, Z = 5.785, P = 0.000). The abundance of Streptococcus was decreased in OSCC (SMD = − 0.46, 95% CI: − 0.88 − 0.04, Z = − 2.146, P = 0.032) and in cancerous tissues (SMD = − 0.45, 95% CI: − 0.78–0. 13, Z = − 2.726, P = 0.006). Conclusions: Disturbances in the interactions between enriched Fusobacterium and depleted Streptococcus may participate in or prompt the occurrence and development of OSCC and could be potential biomarkers for detection of OSCC. |  |\n\n1. Introduction  \nOral squamous cell carcinoma (OSCC) is the most common type of malignant tumour found in the oral cavity. More than 481,000 new patients are diagnosed annually worldwide [1]. Despite advancements in surgical techniques, adjuvant radiotherapy, and chemotherapy, the overall 5-year survival rate of OSCC patients is approximately 50%–60%[1–3].
