In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

BACKGROUNDTo evaluate the effect of ⁸⁹SrCl₂ and/or Bonefos in the treatment of bone metastasis from pulmonary carcinoma.

METHODSA total of sixty-seven lung cancer patients with bone metastasis were enrolled in this study, who were divided into three groups: nineteen cases were treated with ⁸⁹SrCl₂; twenty-eight cases with Bonefos; and twenty cases combined ⁸⁹SrCl₂ with Bonefos.

RESULTSThe total relief rate of the bone pain: the ⁸⁹SrCl₂ group was 84.2%, and the Bonefos group was 80.4%, the combination group was 90.0%. There was no statistical difference among three groups (P > 0.05). The effective rate of the bone metastasis: the ⁸⁹SrCl₂ group was 15.7%, the Bonefos group was 10.7%, and the combination group was 45.0%. The combination group had significantly higher effective rate than that of the ⁸⁹SrCl₂ group or the Bonefos group alone (P < 0.05). The rate of improvement of quality of life: the ⁸⁹SrCl₂ group was 47.3%, the Bonefos group was 42.8%, and the combination group was 80.0%. The combination group had significantly higher effective rate than that of the ⁸⁹SrCl₂ group or the Bonefos group alone (P < 0.05). The side effects of three groups were minimal.

CONCLUSIONS⁸⁹SrCl₂ and Bonefos are two effective and safe drugs on relief of pain. Combined ⁸⁹SrCl₂ and Bonefos might be a better therapy for bone metastasis and improvement of quality of life than the single one, and the side effect is slight and tolerable.
