Can Orthopedic Oncologists Predict Functional Outcome in Patients with Sarcoma after Limb Salvage Surgery in the Lower Limb? A Nationwide Study

Accurate predictions of functional outcome after limb salvage surgery (LSS) in the lower limb are important for several reasons, including informing the patient preoperatively and, in some cases, deciding between amputation and LSS. This study aimed to elucidate the correlation between surgeon-predicted and patient-reported functional outcome of LSS in the Netherlands. Twenty-three patients (between six months and ten years after surgery) and five independent orthopedic oncologists completed the Toronto Extremity Salvage Score (TESS) and the RAND-36 physical functioning subscale (RAND-36 PFS). The orthopedic oncologists made their predictions based on case descriptions (including MRI scans) that reflected the preoperative status. The correlation between patient-reported and surgeon-predicted functional outcome was “very poor” to “poor” on both scores (r2values ranged from 0.014 to 0.354). Patient-reported functional outcome was generally underestimated, by 8.7% on the TESS and 8.3% on the RAND-36 PFS. The most difficult and least difficult tasks on the RAND-36 PFS were also the most difficult and least difficult to predict, respectively. Most questions had a “poor” intersurgeon agreement. It was difficult to accurately predict the patient-reported functional outcome of LSS. Surgeons’ ability to predict functional scores can be improved the most by focusing on accurately predicting more demanding tasks.

Functional Scores

Purpose.In all patients treated at the Centre for Bone and Soft Tissue Sarcomas of Aarhus the functional outcome is prospectively evaluated by use of the Enneking system for the functional evaluation after surgical treatment of tumours of the musculoskeletal system. This system has been accepted by the Musculoskeletal Tumour Society and the International Symposium on Limb Salvage.Patients/methods.In the present study the functional outcome after limb-salvage surgery (89 patients) and amputation (58 patients) was compared. In the limb-salvage group the treatment was surgery alone in 50% and surgery combined with either radiotherapy in 39% or chemotherapy in 11%. Inclusion criteria were: Deep seated extremity sarcomas, age >14 years, more than 1 year post-treatment follow-up time and alive at the end of the study. Median age was 49 years (range 14–88 years). Median tumour diameter was 8 cm (range 1–20 cm), median follow-up time was 4.8 years (range 1–11 years). Wilcoxon andχ2-tests were used for statistical analyses.Results.The two groups were comparable according to age, sex, size of tumour, type of tumour, location of tumour, as well as post-treatment follow-up time. The functional scores were significantly higher after limb-salvage surgery as compared to amputation, the median scores being 85 and 47, respectively (p<0.001). A similar difference was observed if the Enneking scores were subdivided into general health-related scores and extremity-related scores. No association was found between functional scores and the following factors by use of univariate analysis: size of tumour, radiation therapy, localization of tumour and surgical margin.Discussion.We conclude that this study indicates that limb-salvage surgery is associated with a better functional outcome than that observed after amputation. However, whether this also indicates a difference in quality of life needs further studies.

Background: Limb salvage surgery with or without radiotherapy and/or chemotherapy is the mainstay of treatment of Soft Tissue Sarcoma (STS). Though, many studies are found regarding the demographics and result of such malignancy from other parts of the world, such data is not available from our country. This study aimed to analyze the demographic data and functional outcome of STS treated with limb salvage surgery. Methods: It is a retrospective review of 16 cases of soft tissue sarcoma of extremities and trunk managed with limb salvage surgery followed by adjuvant radiotherapy and/or chemotherapy in indicated cases from 2012 to 2017. Demographic data and functional score after 2 years of surgery were analysed and presented. Results: There were 14 male and 2 female cases of STS with mean age of 32.88 years. The most common STS was liposarcoma (37.5%) followed by rhabdomyosarcoma (25%) and synovial sarcoma (18.8%). Extremity and lower limb were the most common sites. Mean MSTS functional score at the last follow up was 24.56 (81.83%) with range from 19-29 (63.33%-96.66%). There were good to excellent results in 13 cases (81.25%) and moderate result in 3 cases (18.75%) according to MSTS functional score. There was positive correlation of MSTS with age, radiotherapy, chemotherapy and negative correlation with grade of tumor. Conclusions: This study showed good to excellent functional results in 81.25% of cases as per Musculoskeletal Tumor Society Score (MSTS) with positive correlation with radiotherapy, chemotherapy, age and negative correlation with grade of tumor.

Discussion. Thirty of 36 patients (83%) presenting with foot and ankle STS or fibromatosis were candidates for limb preservation. With excellent local control and good functional outcome demonstrated in this study, limb salvage should be a primary goal in the management of selected patients with STS and fibromatosis of the foot and ankle.
