AIM: The aim of this study was to estimate nationally the survival of children, adolescents, and young adults with head and neck soft tissue sarcomas.

MATERIALS AND METHODS: The authors included patients aged 0 to 21 years and diagnosed with rhabdomyosarcoma (RMS) or nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) located in the head and neck between 1980 and 2014. Survival probabilities were estimated using the Kaplan-Meier method. The authors estimated the effect of covariates with univariate and multivariate Cox regression analyses. The cumulative recurrence in RMS was estimated when considering death as a competing risk.

RESULTS: We identified 72 patients (50% male individuals, whereas 72% had RMS). Elder patients (older than 15 y) did worse compared with younger patients (log-rank test P=0.001). Patients diagnosed from 1980 to 1999 did worse than patients diagnosed from 2000 to 2014 (log-rank test P=0.02). Similarly, younger (younger than 15 y) patients did significantly better when diagnosed from 2000 to 2014 with reference to those diagnosed from 1980 to 1999 (log-rank test P=0.026). The multivariate hazard ratio was 0.46 (95% confidence interval, 0.23-0.92) for patients diagnosed from 2000 to 2014 with reference to patients diagnosed from 1980 to 1999. The 1-year cumulative recurrence for RMS was 21.2% (95% confidence interval, 12.3%-35.0%).

CONCLUSION: Overall survival has improved throughout the study period, which is attributable to advancement in diagnostics, treatment, and the application of standardized guidelines from international protocols.
