Abstract
Aim
Patients treated with limb salvage surgery for bone sarcomas of the extremities (upper and lower) may have physical disability as a result of treatment. Goal of this study was to evaluate the quality of life after treatment (chemotherapy and conservative surgery) at long term.
Method
208 patients resected for a bone sarcoma and with prosthetic reconstruction (45 in the upper and 163 in the lower limb) were evaluated. Assessment of results was done using the Karnofsky Scale (K.S.). Patients were followed in the clinic and functional results assessed according to the Musculoskeletal Tumour Society (MSTS) system. Moreover the Toronto Extremity Salvage Score questionnaire (TESS) was mailed to 144 patients.
Results
Before treatment 157 patients had a Karnofsky index between “50%” and “70%”, 96 patients between “0%” and “40%”. After treatment 94 patients had a Karnofsky index between “80%” and “100%”, 54 between “50%” and “70%”, and 34 below “40%”. Twentysix patients died with disease.
For the upper limb MSTS system showed a mean value of 80%, with excellent or good results (MSTS score between 30 and 15) in 43 patients, fair or poor results (MSTS score between 14 and 0) in 2 patients. For the lower limb MSTS system showed a mean value of 76.6%, with excellent or good results in 145 patients (89%), fair or poor results in 18 patients (11%). TESS questionnaire was sent back by eighty two patients.
TESS was recorded an average of 3.7 years (upper limb) and 4.2 years (lower limb) after reconstruction. Mean TESS was similar in upper (75.3%) and lower (78.3%) limbs, but differed with age (patients older than 25 years had worse scores).
Conclusion
The 3 analyzed methods showed a good quality of life after treatment. The subjective view of K.S. and TESS is aligned with the MSTS results.
