Intercalary allograft reconstruction following femoral tumour resection: mid- and long-term results and benefits of adding a vascularised fibula autograft. World J Surg Oncol 2022; 20:195. [PMID: 35698130 PMCID: PMC9195446 DOI: 10.1186/s12957-022-02650-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 05/24/2022] [Indexed: 11/30/2022] Open
Abstract
Purpose Bone healing in femoral reconstructions using intercalary allografts can be compromised in a tumour context. There is also a high revision rate for non-union, infection, and fractures in this context. The advantages and disadvantages of an associated vascularised fibula graft (VFG) are still a matter of debate. Methods In a multicentre study, we retrospectively analysed 46 allograft reconstructions, operated on between 1984 and 2017, of which 18 were associated with a VFG (VFG+) and 28 without (VFG−), with a minimum follow-up of 2 years. We determined the cumulative probability of bone union as well as the mid- and long-term revision risks for both categories by Kaplan-Meier survival analysis and a multivariate Cox model. We also compared the MSTS scores. Results Significant differences in favour of VFG+ reconstruction were observed in the survival analyses for the probability of bone union (log-rank, p = 0.017) and in mid- and long-term revisions (log-rank, p = 0.032). No significant difference was observed for the MSTS, with a mean MSTS of 27.6 in our overall cohort (p = 0.060). The multivariate Cox model confirmed that VFG+ was the main positive factor for bone union, and it identified irradiated allografts as a major risk factor for the occurrence of mid- and long-term revisions. Conclusion Bone union was achieved earlier in both survival and Cox model analyses for the VFG+ group. It also reduced the mid- and long-term revision risk, except when an irradiated allograft was used. In case of a tumour, we thus recommend using VFG+ from a fresh-frozen allograft, as it appears to be a more reliable long-term option.

Abstract
The main issues pertaining to oncological surgery of the musculoskeletal system are tumour resection with sufficient margins, and the coverage of inherent defects. We report the use of a pedicled cutaneous groin flap as coverage for a trochanteric defect following an oncological resection of a grade III pleomorphic soft tissue sarcoma in a 75-year-old patient. This flap is not routinely used in the coverage of a defect in this region. The interest of this original process lies in its technical ease, and in the possibility of lifting the flap directly after resection, without changing the set-up.

Abstract
BACKGROUND Hand sarcomas frequently suffer from a delayed diagnosis, and the current guidelines for their management are often not followed. METHODS The objectives of our study were to determine: (1) the rate of inadequate initial treatments; (2) the rates of mortality, recurrence, and complementary excision in a cohort of patients with a sarcoma of the hand who were treated at our reference center between 2000 and 2015. RESULTS The series comprised 26 patients (mean age 40 years). Of the 20 patients not initially treated at a reference center, 17 had inadequate initial treatment. Of the six patients treated at our center, one had inadequate initial care. Significantly more patients had inadequate initial care outside a reference center (p=0.0045). The cumulative probabilities of recurrence or metastases at 5 years were 15% and 30%, respectively. Survival by cumulative incidence was 71% at 5 years and 56% at 10 years. CONCLUSIONS Sarcomas of the hand are a deadly pathology. All diagnostic uncertainty warrants referral of the patient to a reference center. LEVEL OF PROOF IV.

Abstract
The surgical treatment of acetabular bone metastases rests on total hip arthroplasty (THA). In the event of major bone defects, the reconstruction may prove challenging. Two complicating factors are the need to obtain a mechanically stable acetabulum and the unfeasibility of using an autograft to increase the bone stock. The technique described in 1981 by Harrington involves implanting steel rods to reinforce the pelvis before sealing the prosthetic cup. We have now been using this technique for several years, and based on our accumulated experience we introduced several substantial modifications. The most important among them is the use of a Kerboull acetabular reinforcement device (KARD) in addition to the iliac pins. This reinforcement of the acetabulum, which is widely used for THA, serves as the basis for guiding the reconstruction, while also facilitating the sealing of the prosthetic cup. Furthermore, we use centrally threaded rods to avoid secondary displacement. Finally, we routinely use a dual-mobility cemented cup to decrease the risk of dislocation. Here, we describe our acetabular reconstruction technique based on a modified Harrington technique, which is used for acetabular reconstruction in patients with advanced acetabular metastases managed at our French referral centre.

Proximal femur versus acetabular extra-articular resection of the hip joint for primary malignant bone tumors: a retrospective comparative review of 33 cases. World J Surg Oncol 2022; 20:168.

Abstract
Introduction Extra-articular resection (EAR) of the hip joint is prone to significant complications and morbidity. Thus, this study evaluates the cumulative incidences and main reasons of reoperation following EAR of primary malignant bone tumors (PMBT) of the hip to determine whether the outcomes are different between EAR of the pelvis and that of the proximal femur. Patients and methods Thirty-three patients presented with a PMBT of the proximal femur or pelvis were included in this study. Among all PMBTs, 58% originated from the pelvis and 42% were from the proximal femur. Twenty patients had chondrosarcomas (61%), 10 had osteosarcomas (30%), and 3 had sarcomas of another histological subtype (9%). Results The mean follow-up was of 76 months (range: 24–220 months). The cumulative probabilities of revision for any reason were 52% (95% confidence interval [CI] 30–70%) 5 years after surgery. The 5-year cumulative probabilities of revision were 13% (95% CI 4–27%), 24% (95% CI 10–42%), and 34% (95% CI 14–56%) for mechanical, infectious, and tumoral reasons, respectively. The 5-year cumulative probabilities of revision for any reason were 78% (95% CI 37–94%) and 14% (95% CI 2–38%) for the pelvis and proximal femur, respectively (p = 0.004). Posterior column preservation was significantly associated with more mechanical complications even after adjusting for the resection site (p = 0.043). Conclusion Half of patients undergoing EAR of the hip joint for PMBT of the proximal femur or acetabulum will require another operation. EAR of the pelvis is associated with significantly worse outcome than EAR of the proximal femur.

Abstract
IMPORTANCE Multidisciplinary prehabilitation before total knee replacement (TKR) for osteoarthritis may improve outcomes in the postoperative period. OBJECTIVE To compare multidisciplinary prehabilitation with usual care before TKR for osteoarthritis in terms of functional independence and activity limitations after surgery. DESIGN, SETTING, AND PARTICIPANTS This prospective, open-label randomized clinical trial recruited participants 50 to 85 years of age with knee osteoarthritis according to the American College of Rheumatology criteria for whom a TKR was scheduled at 3 French tertiary care centers. Recruitment started on October 4, 2012, with follow-up completed on November 29, 2017. Statistical analyses were conducted from March 29, 2018, to March 6, 2019. INTERVENTIONS Four supervised sessions of multidisciplinary rehabilitation and education (2 sessions per week, at least 2 months before TKR, delivered to groups of 4-6 participants at each investigating center; session duration was 90 minutes and included 30 minutes of education followed by 60 minutes of exercise therapy) or usual care (information booklet and standard advice by the orthopedic surgeon) before TKR. MAIN OUTCOMES AND MEASURES The short-term primary end point was the proportion of participants achieving functional independence a mean (SD) of 4 (1) days after surgery defined as level 3 on the 4 functional tests. The midterm primary end point was activity limitations within 6 months after TKR assessed by the area under the receiver operating characteristic curve of the self-administered Western Ontario Questionnaire and McMaster Universities Osteoarthritis Index function subscale. RESULTS A total of 262 patients (mean [SD] age, 68.6 [8.0] years; 178 women [68%]) were randomized (131 to each group). A mean (SD) of 4 (1) days after surgery, 34 of 101 (34%) in the experimental group vs 26 of 95 (27%) in the control group achieved functional independence (risk ratio, 1.4; 97.5% CI, 0.9-2.1; P = .15). At 6 months, the mean (SD) area under the curve for the Western Ontario Questionnaire and McMaster Universities Osteoarthritis Index function subscale was 38.1 (16.5) mm2 in the experimental group vs 40.6 (17.8) mm2 in the control group (absolute difference, -2.8 mm2; 97.5% CI, -7.8 to 2.3; P = .31 after multiple imputation). No differences were found in secondary outcomes. CONCLUSIONS AND RELEVANCE This randomized clinical trial found no evidence that multidisciplinary prehabilitation before TKR for osteoarthritis improves short-term functional independence or reduces midterm activity limitations after surgery.

Abstract
The benefit of chemotherapy (CT) in rare bone sarcomas is not documented in prospective studies. Our retrospective study from the French sarcoma network for bone tumors ResOs was performed in adult patients (pts) from 1976 to 2014, with histologically verified diagnosis of leiomyosarcomas (LMS), undifferentiated pleomorphic sarcoma (UPS) or radiation-associated sarcomas of bone. The median follow-up was 4.7 years (95% CI: 3.7-6.5). Clinical features, treatment modalities and outcomes were recorded and analyzed from 145 pts (median age 53 years [range 20-87]). Site of disease was extremities (66%) or axial skeleton (34%), 111 (77%) presented with localized and potentially resectable disease. The most common histological subtypes were UPS (58%) and LMS (33%); 58% were high-grade tumors. Surgery was performed in 127 pts. In the 111 localized pts, 28 pts (25%) underwent upfront surgery or exclusive radiotherapy (RT; >50 Gy) without CT, whereas 83 pts (75%) received either neoadjuvant (n = 26) or adjuvant CT (n = 13) or both (n = 44). Neoadjuvant and adjuvant CT was mostly doxorubicin-based (95%/86%) and cisplatin-based (67%/63%). R0 resection was achieved in 59 pts, and a good histological response in 15 patients (25%). Adjuvant RT was performed in 24 (22%) pts. For the whole cohort (n = 145), the 5-year overall survival (OS) rate was 53% [42; 62]. In univariate analysis, age ≤ 60 was associated with a longer disease-free survival (DFS) (P = .0436). Neoadjuvant and adjuvant CT tended to be associated with better DFS (P = .056) with no significant impact on OS in this retrospective series.

Abstract
PURPOSE Undiagnosed and undertreated posterior malleolus fractures lead to early ankle instability and arthritis. A preoperative CT scan could improve the management of those fractures. This study assessed the benefits of a systematic ankle CT scanner to diagnose and manage posterior malleolus fracture. METHODS A monocentric retrospective cohort study was conducted. Sixty consecutive patients with bimalleolar fractures were operated and underwent a preoperative CT scan. The mean age was 50.0 years old (18.6 years old) with a mean body mass index of 20.3 (kg/m2) (11.4 kg/m2) and 71.7% (43/60) of women. The primary outcome was the rate of posterior malleolus fragment diagnosed on X-rays and on CT scan. Secondly, interobserver and interobserver's agreement were compared between conventional X-rays and CT scan. RESULTS Thirty-five (58.3%) posterior fragment fractures were observed on X-rays and 53 (88.3%) on the preoperative CT scan (p < 0.01). The intraobserver reproducibility for X-rays was low (0.02 [- 0.23; 0.27]) and moderate for CT scan (0.45 [0.0; 0.84]). The interobserver reproducibility for X-rays was moderate (0.39 [0.15; 0.60]) and excellent for CT scan (0.78 [0.0; 1.0]). CONCLUSION A wide proportion of bimalleolar fractures are associated with posterior malleolus fractures and undiagnosed with standard X-rays. We advocate a systematic preoperative CT scan in the management of bimalleolar fractures. LEVEL OF EVIDENCE Level IV, retrospective cohort study.

Comparative study of traction table versus standard table. Orthop Traumatol Surg Res 2021; 107:102752. [PMID: 33316445 DOI: 10.1016/j.otsr.2020.102752] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 08/20/2020] [Accepted: 09/24/2020] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Primary total hip replacement (THR) comes with a risk of leg length discrepancy (LLD), which occurs in 25 % of cases, especially when the surgery is done using an anterior approach on a traction table, since it is not easy to verify the lengths of the legs. By doing the anterior approach on a standard table an intraoperative visual evaluation of leg lengths can be done after the trial implants are in place. As far as we know, the ability to set the leg length has not been compared between procedures done on a standard table or a traction table. This led us to carry out a retrospective comparative study to determine whether using a standard table for anterior THR will 1) allow better control over leg length, 2) increase the risk of incorrect implant positioning, 3) increase the surgical complication rate. HYPOTHESIS Anterior THR on a standard table will allow better control over leg length than anterior THR on a traction table. MATERIAL AND METHODS This single center retrospective study included 266 THRs done between January 1, 2018 and November 2, 2019 for primary (n=219) or secondary (n=47) hip osteoarthritis. The 137 cases done with a traction table were compared to the 129 cases with a standard table. The two groups were comparable in terms of age, sex, body mass index, indication and bilateral implants. They were not comparable in the surgeon experience (more junior surgeons in the standard table group [p<0.001]) and types of implants used (more cementless cups and stems in the standard table group [p=0.001]). Radiographs were used to measure the LLD, cup inclination, and femoral stem placement in the frontal plane. Any early complications were documented. The target was for the operated leg to be the same length as the contralateral leg, which was defined as within 10mm of each other. RESULTS The mean postoperative LLD was comparable between the traction table group 1.56±7.32 mm (min -15.6 max 17.2) and the standard table group 0.53±6.93 mm (min -16.4 max 13.7) (p=0.24). In the traction table group, 81 % (111/137) of patients had legs of the same length, versus 84 % (109/129) in the standard table group (p=0.7). Cup inclination was comparable with a mean of 40.4±7.1 degrees (min 23.4; max 58.5) in the traction table group versus 39.3±7.5 degrees (min 19.9; max 60.9) in the standard table group (p=0.21). The frontal position of the femoral stem was comparable between groups with a mean of 0.09±0.45 degrees (min -1; max 3.98) in the traction table group versus 0.08±0.59 degrees (min -4.97; max 1.93) in the standard table group (p=0.86). There were 5 complications (3.7 %) in the traction table group versus 11 (8.5 %) in the standard table group (p=0.16). CONCLUSION Use of a standard table to carry out THR by the direct anterior approach does not provide better control over leg length than using a traction table, subject to preoperative planning. When doing the procedure on a standard table, the implant placement is at least comparable, with a similar risk of complications. LEVEL OF EVIDENCE III; case matched study.

Abstract
Parosteal osteosarcomas and well-differentiated liposarcomas are both well-differentiated locally aggressive tumors. They both have simple karyotypes with amplification of the 12q13-15 regions including MDM2 and CDK4 genes. In this report, we describe the case of a parosteal osteosarcoma intertwined with a low-grade component similar to a well-differentiated liposarcoma. The association of a bone component with an adipose component was initially overlooked. We describe the histological, imaging, and molecular characteristics of this tumor stressing the importance of radio-pathological correlation. To our knowledge, this is the second report of a parosteal osteoliposarcoma. Awareness of this rare presentation may allow radiologists and surgeons to recognize the peripheral fatty component as an integral part of the tumor.

Abstract
PURPOSE Chronic ankle instability is the main complication of ankle sprains and requires surgery if non-operative treatment fails. The goal of this study was to validate a tool to quantify psychological readiness to return to sport after ankle ligament reconstruction. METHODS The form was designed like the anterior cruciate ligament-return to sport after injury scale and "Knee" was replaced by the term "ankle". The ankle ligament reconstruction-return to sport after injury (ALR-RSI) scale was filled by patients who underwent ankle ligament reconstruction and were active in sports. The scale was then validated according to the international COSMIN methodology. The AOFAS and Karlsson scores were used as reference questionnaires. RESULTS Fifty-seven patients (59 ankles) were included, 27 women. The ALR-RSI scale was strongly correlated with the Karlsson score (r = 0.79 [0.66-0.87]) and the AOFAS score (r = 0.8 [0.66-0.87]). A highly significant difference was found in the ALR-RSI between the subgroup of 50 patients who returned to playing sport and the seven who did not: 68.8 (56.5-86.5) vs 45.0 (31.3-55.8), respectively, p = 0.02. The internal consistency of the scale was high (α = 0.96). Reproducibility of the test-retest was excellent (ρ = 0.92; 95% CI [0.86-0.96]). CONCLUSION The ALR-RSI is a valid, reproducible scale that identifies patients who are ready to return to the same sport after ankle ligament reconstruction. This scale may help to identify athletes who will find sport resumption difficult. LEVEL OF EVIDENCE III.

Background: Neoadjuvant chemotherapy with intercalated surgery is the standard of care for resectable high-grade bone sarcoma (BS) but identification of biomarkers for chemosensitivity prediction is still needed. Insulin-like Growth Factor (IGF) pathway was first linked with sarcoma biology approximately 30 years ago (El-Brady OM, 1990).
Methods: We recruited 138 pts with newly diagnosed primary localized or metastatic BS. We measured fasting blood glucose and insulin, body mass index (BMI). The HOMA-IR (Homeostasis Model Assessment) score ((Glucose (mmol/l) x Insulin) / 22.5), which has been proven to reliably detect insulin resistance IR was calculated, and patients with HOMA-IR > 2.6 were considered as IR. We collected characteristics usually associated with insulin resistance: age, obesity, diabetes, dyslipidemia and hypertension.
Results: Out of 138 pts, 50 (36%) were insulin resistant: HOMA-IR >2.6. Thirty-two IR patients (64%) had no cardiovascular risk factor. In univariate analysis, IR was associated with obesity (BMI > 30 kg/m2)(22% vs 3%, p=0.0015), but not with age (median 36,8 vs 41 years, p=0.19). IR was more prevalent in Ewing sarcoma (14/29; 48%) and chondrosarcoma (7/16; 44%) followed by osteosarcoma (25/67; 37%) and other rare bone sarcomas (4/26; 15.3%), but not significantly (p=0.097). After neoadjuvant chemotherapy and surgery of Ewing tumor and osteosarcoma, pathologic tumor necrosis was higher in IR pts (88.9 vs 75%, p= 0.028).
Conclusion: Our results suggest that metabolic profile may help to discriminate best candidates for neoadjuvant chemotherapy in high-grade bone sarcomas. Further studies are needed to confirm and explain these results.

Abstract
Rupture of the patellar tendon is an infrequent pathology, and surgical repair with nonabsorbable sutures is the gold standard for management. Many surgeons augment the repair using one of many proposed methods: cerclage wires, Dall-Miles cables, autologous hamstring grafts, and tendon allografts. In this study, we propose the augmentation of patellar tendon repair using an artificial ligament. The questions to be assessed in this study are as follows: (1) measurement of functional results 1 year after surgery using the Lysholm score and (2) the incidence of both rerupture, and surgical complications within the first year postsurgery, the median knee range of motion at 3 months and 1-year postsurgery, patient satisfaction, and postsurgery patellar height, measured using the Caton-Deschamps Index. In our center, we performed 30 suture repairs of traumatic patellar tendon ruptures between 2015 and 2016. Tendon repair was always augmented using an artificial ligament (LT60, Orthomed). The results were evaluated 1 year after surgery. The 1-year postsurgery median Lysholm score was 96 (first quartile-third quartile [Q1-Q3]: 95-100). None of the following complications were reported: second surgery for any reason, new rupture, and superficial or deep infection. Radiological analysis showed a median Caton Index of 1 (Q1-Q3: 0.9-1) postsurgery. Excellent Lysholm scores were observed 1 year after synthetic ligament augmentation of patellar tendon sutures, with a low rate of complications compared with published studies.

A case-matched study with and without traction table. Orthop Traumatol Surg Res 2020; 106:583-588. [PMID: 32253137 DOI: 10.1016/j.otsr.2020.01.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Revised: 12/30/2019] [Accepted: 01/21/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND The costs incurred by management of displaced femoral neck fracture are a public health issue. The anterior approach can be used for partial hip replacement, but costs in terms of equipment and time incurred by using a traction table have not to our knowledge been estimated in this indication. We therefore performed a case-control study, comparing (1) installation and deinstallation times (IT, DT) in partial hip replacement using a standard versus a traction table (ST, TT), and (2) operating times, limb-length radiography and intraoperative complications. HYPOTHESIS Performing the anterior approach on a standard table saves installation and deinstallation time and operating time, without leading to more intraoperative complications. MATERIALS AND METHODS A comparative retrospective study included 102 patients (mean age, 84.8±8 years; 46 ST, 56 TT). Installation time (IT) was calculated between entry in the operating room and performance of the incision; operating time (OT) between incision and closure; and deinstallation time (DT) between closure and leaving the operating room. RESULTS Mean IT in ST (25.5±6.2min) was significantly shorter than in TT (33.9±6.2min) (p=1.1*10-9), as were DT (13±4.7 versus 17±3.4min) (p=4.1*10-6) and OT (73.5±15.9 versus 82.6±21.3minutes) (p=0.01). There were 4 intraoperative complications: 1 greater trochanter fracture in ST and 2 greater trochanter fractures and 1 proximal femoral fracture in TT. Limb-length discrepancy was comparable between ST (3.7±3.2mm (range, 0-15mm)) and TT (5.3±4.6mm (range, 0-20mm)) (p=0.06). DISCUSSION Patient installation on a standard table reduced installation, deinstallation and operating time compared to use of a traction table, without increasing the complications rate. LEVEL OF EVIDENCE III, case-control study.

Abstract
BACKGROUND The aim of this retrospective study was to evaluate the clinical, radiologic, and survival results of dual mobility (DM) sockets in revision total hip arthroplasty (THA) performed for instability versus revision THAs performed for other reasons. METHODS From a computerized database, we identified 84 revision THAs using a modern DM socket performed in 81 patients with a mean age of 71 years. Indication for revision was recurrent dislocation in 47 hips, and other reasons in the remaining 37 hips. A survivorship analysis according to the actuarial method was carried out on the entire series using revision for any cause, revision for dislocation, and radiological cup loosening revised or not, as the end points. RESULTS Of the 81 patients, twelve died, six were lost to follow-up, eight had been revised, and 55 patients (58 hips) were unrevised and alive at a mean follow-up of 6.4 years. Dislocation occurred in four of the 47 (8.5%) hips for which indication for revision was dislocation versus one of the remaining 37 (2.7%) hips [odds ratio = 3.4 (0.4-31.3), p = 0.07]. According to our criteria, three acetabular components of which one was revised were considered as loosened. When using revision for dislocation as the end-point, the survival rate at seven years was 90.4 ± 5.3% (IC95%, 79.9-100) in the 47 hips for which the indication for revision was dislocation versus 100% in the remaining 37 hips (log-rank, p = 0.5). CONCLUSIONS The current study indicated that DM sockets represent an interesting solution to prevent dislocation in revision THAs at mid-term follow-up.

Abstract
Chondrosarcomas are primary cancers of cartilaginous tissue with highly contrasting prognoses. These tumors are defined by recurrent mutations in the IDH genes and other genetic alterations including inactivation of CDKN2A and COL2A1; however, these have no clinical value. Here we use multi-omics molecular profiles from a series of cartilage tumors and find an mRNA classification that identifies two subtypes of chondrosarcomas defined by a balance in tumor differentiation and cell cycle activation. The microRNA classification reveals the importance of the loss of expression of the 14q32 locus in defining the level of malignancy. Finally, DNA methylation is associated with IDH mutations. We can use the multi-omics classifications to predict outcome. We propose an mRNA-only classifier to reproduce the integrated multi-omics classification, and its application to relapsed tumor samples shows the progressive nature of the classification. Thus, it may be possible to use mRNA-based signatures to detect patients with high-risk chondrosarcomas.

Abstract
In the OS2006 study, patients younger than 18 years were treated with a methotrexate-based regimen (MTX), patients older than 25 years with a doxorubicin-cisplatin-ifosfamide-based regimen (API-AI), whereas patients aged 18-25 years received either API-AI or MTX. We herein report the prespecified subgroup analysis of the outcome of 106 patients treated with API-AI. Preoperative chemotherapy combined three doxorubicin-ifosfamide-cisplatin (API) and two doxorubicin-ifosfamide (AI) courses. Postoperative chemotherapy was assigned by risk group: localised patients with a good histological response (<10% viable cells) received two AI and two cisplatin-ifosfamide (PI) courses; patients with synchronous metastases, poor histological response or unresectable primary received five cycles of etoposide-ifosfamide (EI). Of the 106 patients, 61 were randomised to receive or not zoledronate. Median age was 30 years (range 18-67), 66 (62%) patients were >25 years. The primary tumours were axial in 28 patients (26%), and 28 (26%) presented with metastases. Ninety-six patients (91%) had surgery, conservative in 82 (85%); 36 patients (38%, 95% CI 28-48%) were good responders. Toxicity was manageable, with no significant difference in severe acute toxicity between patients aged >25 years and those younger. With a median follow-up of 4.8 years, the 5-year event-free survival and overall survival rates were 46% (95% CI 36-56) and 57% (95% CI 47-67), respectively. The primary tumour size and initial metastases correlated with a higher risk of event. In these 106 osteosarcoma adult patients, API-AI proved feasible with no excess of toxicity, and favourable activity despite poor-prognosis factors.

Abstract
BACKGROUND NETSARC (netsarc.org) is a network of 26 sarcoma reference centers with specialized multidisciplinary tumor boards (MDTB) aiming to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB and expert pathological review are mandatory for sarcoma patients nationwide. In the present work, the impact of surgery in a reference center on the survival of sarcoma patients investigated using this national NETSARC registry. PATIENTS AND METHODS Patients' characteristics and follow-up are prospectively collected and data monitored. Descriptive, uni- and multivariate analysis of prognostic factors were conducted in the entire series (N = 35 784) and in the subgroup of incident patient population (N = 29 497). RESULTS Among the 35 784 patients, 155 different histological subtypes were reported. 4310 (11.6%) patients were metastatic at diagnosis. Previous cancer, previous radiotherapy, neurofibromatosis type 1 (NF1), and Li-Fraumeni syndrome were reported in 12.5%, 3.6%, 0.7%, and 0.1% of patients respectively. Among the 29 497 incident patients, 25 851 (87.6%) patients had surgical removal of the sarcoma, including 9949 (33.7%) operated in a NETSARC center. Location, grade, age, size, depth, histotypes, gender, NF1, and surgery outside a NETSARC center all correlated to overall survival (OS), local relapse free survival (LRFS), and event-free survival (EFS) in the incident patient population. NF1 history was one of the strongest adverse prognostic factors for LRFS, EFS, and OS. Presentation to an MDTB was associated with an improved LRFS and EFS, but was an adverse prognostic factor for OS if surgery was not carried out in a reference center. In multivariate analysis, surgery in a NETSARC center was positively correlated with LRFS, EFS, and OS [P < 0.001 for all, with a hazard ratio of 0.681 (95% CI 0.618-0.749) for OS]. CONCLUSION This nationwide registry of sarcoma patients shows that surgical treatment in a reference center reduces the risk of relapse and death.
