Abstract

Introduction Chondrosarcoma (CS) is most common primary osseous tumor of the chest wall. The aim of this study was to report results from surgical procedures and evaluate clinical factors predicting survival of patients with chest wall CSs treated in a single tertiary sarcoma center. Materials and Methods Fifty patients with primary CS located in the ribs and sternum were included. Details of the clinical data and oncological outcomes, including local recurrence (LR) and disease-specific survival (DSS), were collected. Results The tumor was primarily originated in the sternum in 6 patients (12.5%) and in ribs 2 to 11 in the remaining patients. Specimens were histologically graded 1 in 13 patients (26%), 2 in 28 (56%), 3 in 8 (16%), and 1 (2%) as mesenchymal grade 3 CS. R0 margins were obtained in all cases. Reconstruction was warranted in 47 (94%) cases. Local recurrence developed in 3 (6%) patients, and the median time to LR was 17 (range, 16–68) months. Eight (16%) patients developed metastasis. Increasing tumor volume was a statistically significant factor for reduction of DSS. Conclusions Chondrosarcoma of the chest wall can be treated effectively with clear margins, resulting in lower LR rate and higher DSS than CS of the extremities and pelvis. Metastasis of the chest wall mostly occurs in high-grade tumors, and the locations of the metastases differ greatly from those observed in CS of the extremities and pelvis. Metastases are commonly extrapulmonary, indicating the need for postoperative follow-up with multiple imaging modalities to monitor recurrence and metastases.
