Background

Primary sarcomas originating from the bones of hand and wrist are rare but carry a significant burden of morbidity.

Methods

National Cancer Institute's Surveillance, Epidemiology and End Result database from 1975 to 2017 was queried to report incidence and survival data in 237 patients in the United States. Kaplan-Meier and Cox regression were used to determine the prognostic factors affecting survival. χ² test was used to assess the correlation.

Results

Incidence of hand and wrist sarcoma was 0.017 per 100 000 persons in 2017 and has not significantly changed since 1975 (p > 0.05). Disease-specific 5-year and 10-year survival for the entire cohort was 90% and 84%, respectively. On multivariate analysis race "others," histology other than "osteosarcoma," "undifferentiated" grade, and size "≥6 cm" were predictors of worse disease-specific survival. Cross-tabulation of race with other significant prognostic factors on univariate analysis revealed a significant correlation of race with every other significant prognostic factor except for grade.

Conclusions

The current study is an analysis of a population-based registry reporting incidence and survival data for patients with sarcoma of hand and wrist. Independent prognostic factors include race, histology, grade, and size. There is a lack of improvement in survival over the last four decades.
