Bone Metastases Pattern in Newly Diagnosed Metastatic Nasopharyngeal Carcinoma: A Real-World Analysis in the SEER Database

الملخص EN

Objective.

To evaluate the prevalence rate and survival situation of bone metastases in initial nasopharyngeal carcinoma (NPC) patients and the hazard and forecast elements of bone metastases NPC patients.

Patients and Methods.

The data collected from Surveillance, Epidemiology, and End Results (SEER) program between 2010 and 2016 were evaluated.

Univariate and multivariable logistic analysis and the Cox regression were carried out to estimate predictors and elements of the being of bone metastases at diagnosis, respectively.

The overall survival of different subgroups were appraised by log-rank tests and the Kaplan–Meier analysis.

Results.

Factors including male sex, higher N stage, presence of liver, and brain or lung metastases were largely related to the occurrence of bone metastases.

The median survival time for bone metastasis NPC patients was 14.0 months.

A factor of more than one primary sequence number predicted worse survival.

Conclusion.

The data offer corresponding risks and prognostic indicators of bone metastases for NPC patients.
