Abstract

INTRODUCTION

In this study, we aimed to analyze the clinical observation and surgical results of the patients having bone invasion suspected with imaging methods invasion with preoperatively having soft tissue sarcomas.

METHODS

We evaluated the retrospective results of 96 STS(soft tissue sarcoma) patients surgically treated between 2005-2015. 16 of these cases were suspected to have bone invasion radiologically. The mean age was 56(18-81). 8 cases were located in proximal femur, 5 were in distal femur, 2 in proximal humerus and one in proximal tibia. These patients were surgically treated with wide resection and reconstruction with endoprosthesis. Mean follow up was 22 months(7-90).

RESULTS

The histological types were: pleomorphic sarcoma in 7, liposarcoma(LS) in 4, synovial sarcoma(SS) in 3 and alveolar soft part sarcoma(ASPS) and malign peripheric nerve tumor(MPNT)in 1 patients. We recorded bone invasion in 6 of 8 proximal femur, 4 in 5 distal femur and 3 proximal humerus and 3 tibia located cases. Wound problems and infection were recorded in 3 and hip dislocation was recorded in one patient. MSTS scores were 90%(88%-94%) for proximal femur, 82%(70%-94%) for distal femur, 72%(65%-76%) for proximal humerus and 45% for proximal tibia.

DISCUSSION AND CONCLUSION

As a conclusion; periost invasion should be examined in patients with the diagnosis of softtissue sarcoma shaving bone medullar invasion with direct roentgenograms and MRI and if no periost invasion is detected, the tumor should be wriggled from the periost and the extremity should be salvaged.
