How to improve the effects of treatment on patients with oral squamous cell carcinoma (OSCC) has always been the focus of clinical and basic studies. The standardized diagnosis and treatment of malignant tumors aim to improve the effects of treatment, and individualized treatment based on standardized diagnosis and treatment may further improve these effects. On the basis of the existing guidelines for the diagnosis and treatment of patients with OSCC, this study explored the opportunities and challenges of standardized and individualized diagnosis and treatment of OSCC. These challenges and opportunities were related to the updates of clinical and pathological staging system, surgical margins, and neck dissection in patients with OSCC at early stage and preoperative induction therapy and postoperative adjuvant treatment in patients with advanced OSCC. This study also shared ideas on clinical studies of OSCC to optimize the existing treatment schemes, improve the treatment effects, and enhance the guidelines.
