Introduction: Osteosarcoma (OS), the most common primary bone tumor, is known to be relatively a radioresistant tumor. Pathological fracture in OS denotes its aggressive biological response and so it was considered a contraindication to limb salvage in earlier days. Radiotherapy has its role only in cases that are inoperable or have poor prognostic factors. In recent years, there have been major advances in the management of pathological fractures in high-grade OS (HGOS). This case report is about the effect of combination chemotherapy and radiotherapy in the management of pathological fracture in HGOS with limb salvage procedure.
Case Report: A 19-year-old male with pain and swelling in his right lower third of thigh and inability to walk for 3 months was diagnosed as a case of OS right distal femur with a pathological fracture. Open biopsy was done which confirmed the diagnosis as HGOS, staged Enneking IIb. He was treated with a combination of chemotherapy, external beam radiotherapy, tumor resection, and modular resection prosthesis.
Results: There were no immediate, early, and late complications. At the end of 1½ years, his functional recovery is good and he has reached more than 70% of the right knee functions. He has no signs of recurrence at present. He has got a better quality of life and functional activity with the prosthesis compared to what an amputated limb can produce.
Conclusion: Pathological fracture in OS is not a contraindication to limb salvage. Radiotherapy can be used in combination with chemotherapy and limb salvage surgery in HGOS with a pathological fracture. This combination treatment helps in increasing the chances of limb sparing surgery with good local control and tumor necrosis rate. The new knowledge that radiotherapy can be effective when used with chemotherapy has shown good result in our case.
