Abstract

INTRODUCTION

Juxtacortical (surface) chondrosarcoma (JCC) is a very rare subtype of chondrosarcoma, mostly seen in young adults. In this study, we aimed to report demographic data and avarage survival rates of JCC.

METHODS

In this study we used the latest version of the Surveillance, Epidemiology and End Results (SEER) database, patients were examined under the titles of gender, age, race / ethnic origin, lesion location in the body, degree of tumor differentiation, applied surgeries and follow-up periods. Descriptive statistics were given as mean ± standard deviation, frequency and percentage.

RESULTS

A total of 52 patients were included in the study, of which 16 were female and 36 were male (69%), with a mean age of 41.3 ± 20.0 years (range: 8-84 years). When examined for ethnicity, it was found that it was seen most in white race (84.6%).The most common localization of tumor lesions was the lower extremity long bones (50%).Low grade tumor (45% of all tumors) was the most common tumor differentiation. The mean follow-up was 125,5 months (range 4 to 358 months).

DISCUSSION AND CONCLUSION

JCC is a very rare type of chondrosarcoma, and often seen as lower grade compared to other types of chondrosarcoma. It's a little more common in men. It tends to settle on the long bones, most commonly on the lower extremity, especially the femoral diaphysis.
