Abstract

INTRODUCTION

Clear cell chondrosarcoma is a rare variant of chondrosarcoma and it is characterized by slow growth and low metastasis potential. The aim of this study is to report the demographic data and survival rates of clear cell chondrosarcomas.

METHODS

This study was conducted using the latest version of the Surveillance, Epidemiology and End Results (SEER) database. Patients with clear cell condrosarcoma were evaluated for age, sex, ethnicity, marital status, disease prognosis, tumor location, tumor grade, follow-up period and follow-up results. The patients were divided into two groups as older than 30 years old and younger than 30 years old. Follow-up results were evaluated as alive and dead in two groups. Descriptive statistics were expressed as mean ± standard deviation, frequency and percentage.

RESULTS

A total of 70 patients 19 women and 51 men (72.8%) with a mean age of 44.4 ± 18.2 std (10-84 years)were included in this study. The most common tumor locations were considered as lower extremity long bones and associated joints (68.5%) When the tumor differentiation was examined, the most common was observed as medium differentiation (grade II) (46.4%). The mean follow-up period was 84.3 months (1-238 months). Of the 70 patients included in this study, 11 (15.7%) died.

DISCUSSION AND CONCLUSION

Although clear cell chondrosarcoma is known as low-grade chondrosarcoma, 78.6% of the patients included in our study were found to be have moderate or advanced tumors. We also have found that the most common age range seen in a wide age range, although known to be aged between 30-50.
