Purpose: Patients who were diagnosed with soft tissue sarcoma (STS) of limbs and met the indications for amputation because of no effective soft tissue coverage after extensive tumor resection were treated with skin flap transplantation and therapeutic courses were observed.  Methods: A total of 23 patients, pathologically diagnosed as soft tissue sarcoma from January 2011 to June 2015 and whose effective soft tissue coverage was not guaranteed due to extensive tumor resections were included. They underwent extensive tumor excision and skin flap grafting. The postoperative follow-up, tumor control and functional recovery was evaluated as per the Musculoskeletal Tumor Society (MSTS) score.  Results: The follow-up time was from 8 to 60 months, with an average follow-up of 39.69 months. Of the 23 patients, 10(43.47%) died of tumor metastasis from 8th to 23rd months after surgery. In these 10 cases, 2 cases (8.70%) subsequently underwent amputation because of local tumor recurrence. The remaining 13 patients are recurrence free till date of follow up. The MSTS limb function score at 3 months after surgery of all patients were 7-28 points, with an average of 22.56 points, and the excellent and fair scores are observed in 91.30% of patients.  Conclusion: For patients who cannot achieve effective soft tissue coverage after extensive resection of soft tissue sarcoma and meet the indications of amputation can have limb preservation by extensive tumor resection combined with skin flap transplantation with a good functional results

AbstractFor patients with tumors of the distal femur, options for limb salvage include tumor resection followed by reconstruction. While reconstruction commonly involves a distal femoral replacement, careful selection of patients with tumor involvement limited to a single condyle may be candidates for reconstruction with distal femur hemiarthroplasty. In these procedures, resection spares considerably more native anatomy. Three consecutive patients who underwent resection and reconstruction at the distal femur with custom unicondylar hemiarthroplasty are presented in this case series at a mean follow-up of 45 months (range, 26–78). In two cases, prostheses were utilized as a secondary procedure after failure of initial reconstruction. In one case, the custom prosthesis was utilized as the primary method of reconstruction. Mean Musculoskeletal Tumor Society disease-specific scores were 26.7 (range, 25–28). All patients achieved a return to full weight bearing, activities of daily living, and functional range of motion. In appropriately selected patients with tumors of the distal femur, reconstruction with custom unicondylar hemiarthroplasty provides benefits including optimal function postoperatively via preservation of tumor-free bone and ligamentous structures. Additionally, maintenance of greater bone stock may confer benefits to patients with pathology at a high likelihood for recurrence and need for subsequent procedures.

Background and Aims: The present standard of care in treating lower extremity soft tissue sarcomas is function-sparing, limb-preserving resection and reconstruction with or without oncological therapy. The aim of this pilot study was to test the suitability and adequacy of the Finnish translations of two functional outcome questionnaires (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society score) and to perform a preliminary investigation of functional outcomes of Finnish lower-limb soft tissue sarcoma patients after operative treatment. Materials and Methods: Between June 2015 and December 2015, consecutive surgically treated outpatients were asked to participate in the study. Demographic, clinical, surgical, and oncological outcome data were collected. Two functional outcome questionnaires were used (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores). A comparative analysis is presented. Results: A total of 19 lower-limb soft tissue sarcoma patients with a mean follow-up time of 2 years and 10 months were included. All (n = 19) invited patients participated in the study. Mean age was 62.3 years. In total, 13 had high-grade sarcomas. Eight wounds were closed directly, four used skin grafts, and five required flap reconstructions. One patient required a tumor prosthesis, and one required a rotationplasty. A total of 14 patients received oncological therapy. No problems or difficulties were reported in using and completing the Finnish versions of the Toronto Extremity Salvage Score or Musculoskeletal Tumor Society questionnaires. The overall Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores were 88 and 76, respectively. Conclusion: This pilot study suggests that the Finnish versions of the Toronto Extremity Salvage Score and Musculoskeletal Tumor Society questionnaires are suitable for measuring functional outcome after lower extremity soft tissue sarcomas treatment. Functional outcomes vary from moderate to excellent.

Introduction: Rhabdomyosarcoma is a soft tissue malignant musculoskeletal tumor frequent in children. Biliary duct localization is extremely rare, but it is the most common cause of malignant obstructive jaundice in pediatric patients. Methods: This report describes a series of 10 patients under 18 years of age with biliary tract rhabdomyosarcoma who were enrolled, from 1979 to 2004, in 3 consecutive Italian pediatric cooperative protocols that had been drawn up by the Soft Tissue Sarcoma Committee of the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP). Results: Considering initial and delayed surgery, tumor resection was achieved in 7 cases, 3 complete with free margins (2 liver transplants) and 4 with microscopic residual disease. Chemotherapy was given to all patients and radiotherapy to 3. At present, 5 patients survive in complete remission 90-200 months after diagnosis while 4 died of disease progression or relapse and 1 of liver transplant-related complications. Conclusions: Better outcomes in this series were associated with the feasibility of conservative surgery due to the favorable location of the tumor, in particular in the common bile duct. Chemotherapy and radiotherapy might obviate the need for demolitive surgery or liver transplant, which were linked to worse outcomes in our series.

Purpose: The femur is prone to nonunion after biologic reconstruction following tumor resection, due to high bending forces. Nonunion at the host–graft junction is difficult to treat since the graft is in an avascular state. We aimed to investigate the clinical and radiographic results of an onlay free vascularized fibular grafting (VFG) as a salvage procedure for nonunion management after biologic reconstruction of the femur following bone tumor resection. Methods: We retrospectively reviewed 10 patients (8 men and 2 women, median age: 15.5 years, range: 10–47) who underwent an onlay VFG for nonunion after intercalary reconstruction of the femur using an allograft ( n = 7) or pasteurized autograft ( n = 3), following tumor resection. The median follow-up period after VFG was 85.7 (24.6–163.5) months. Results: The median time to union between the host bone and the VFG osteotomy sites was 3.5 (2.8–4.5) months. The median time to union at the host–graft junctions was 10.6 (6.6–12.7) months. Two postoperative complications requiring revision surgery occurred in two patients: one graft fracture and one deep infection with synchronous graft fracture. Internal fixation was required in the patient with graft fracture. The patient with the infection and synchronous graft fracture was treated using debridement, antibiotics, and an external fixator. The median Musculoskeletal Tumor Society functional score was 88% (60–97%) at the final follow-up. Conclusion: Onlay VFG as a salvage procedure for nonunion of a biologic intercalary reconstruction of the femur after tumor resection is a useful treatment option.

Rhomboid Flap

Abstract Background: Reconstruction of limb defects following wide resection of large soft-tissue sarcomas (STS) is challenging. Effectiveness of rhomboid flaps in covering these wounds remains to be addressed. Methods: From March 2018 through February 2019, we utilized modified rhomboid flaps to reconstruct limb defects following wide resection of the large STS (≥5 cm in diameter) in 6 patients. There were 3 males and 3 females. The average age was 65 years (47-77 years). Diagnoses included leiomyosarcoma in 3 patients, synovial sarcoma, undifferentiated pleomorphic sarcoma, and myxoid liposarcoma in 1 respectively. The anatomic locations included the anterior knee in 3 cases, upper arm in 2, and thigh in 1. The mean diameter of the tumor measured 10 cm (5-17 cm). The mean defect size was 113 cm2(38-270 cm2). Results: The mean follow-up duration was 10 months (range, 6-12 months), no patients were lost to follow-up. Skin grafts were utilized in 2 cases. The mean time to heal was 7 weeks (range, 3-13 weeks). At final follow-up, there were no recurrence and metastasis. One case had cerebral hemorrhage and 1 had wound dehiscence, whereas no reoperation was performed. The range of motion of the joints adjacent to the flap reconstructions were comparable to preoperative status. The mean Musculoskeletal Tumor Society score was 27 (range, 24-30). Conclusions: The modified rhomboid flap affords great versatility and is easy to design. This technique yields satisfactory effectiveness in reconstructing limb defects after resection of large STS. Long-term studies of large sample size are warranted.

Abstract INTRODUCTION The effect of stereotactic radiosurgery (SRS) dose-rate on tumor control for acoustic neuroma (AN, or vestibular schwannoma) is unclear. METHODS This was a retrospective study of all patients treated for AN with frame-based cobalt-60 SRS at the Toronto Western Hospital between 2005-2019. Dose rates on the day of SRS were calculated from the calibration dose-rate while accounting for the cobalt-60 half-life of 5.2713 years. Local failure was defined as continued tumor growth >36 months post-SRS, tumor resection for LF, or use of any repeat SRS for LF. Cumulative incidence of LF was reported after accounting for competing risks of death, on a per-lesion basis. Comparisons of actuarial LF were made using Gray’s test. Multivariable analysis of LF was performed using a proportional hazards model. RESULTS A total of 607 patients were treated for 617 acoustic neuromas. Median follow-up was 5.0 years. 158 tumors (26%) were cystic. 71 tumors (12%) had previous resection. Nine patients received 10-11 Gy due to large tumor size; all remaining patients received 12 Gy to approximately the 50% isodose line. Median dose rate was 2.4 Gy/min (range, 1.3-3.7). There was no association between dose rate and LF (≥ 2.4 Gy/min vs. < 2.4 Gy/min, 6.07% vs. 6.12% at 5-year follow-up, p = 0.75). The adjusted local failure-specific hazard ratio (HR) for dose rate (per Gy/min) was 1.2 (95% CI 0.69-2.1, p = 0.52). Patients with previous surgery had higher LF, with a HR of 3.6 (95% CI 1.7-7.8, p = 0.0012), after adjusting for presence of cysts (HR 0.27, p = 0.034) and maximum tumor diameter (HR 1.055 per cm, p = 0.071). CONCLUSIONS In a large cohort of patients with acoustic neuromas, radiosurgery dose-rate was not associated with tumor control. Previous resection was a strong risk factor for local failure after SRS.

Background.Although the survival of children with soft tissue sarcoma (STS) has improved considerably, the outcome of patients with metastatic disease, and those with primary tumours of the extremities or parameningeal sites remains disappointing. We describe the clinical outcome of an ifosfamide-based regimen with local therapy directed only to children who failed to achieve a complete response to initial chemotherapy.Patients and Methods.Twenty-one children with STS (16 rhabdomyosarcoma) who presented with unresectable tumours were treated with five courses of ifosfamide (9 g/m2) and etoposide (600 mg/m2). Patients who did not achieve a complete response then received local therapy. Chemotherapy with ifosfamide combined with etoposide, vincristine (1.5 mg/m2and doxorubicin (60 mg/m2) or vincristine and actinomycin D (1.5 mg/m2) was continued for one year.Results and Discussion.Objective responses to five courses of ifosfamide and etoposide were seen in all patients. Disease free survival (DFS) at a median follow up of 59 months was 57% (95% CI 29–75%). The DFS of children who received local therapy was 89% compared with 33% in those who received chemotherapy alone (p=0.027). Locoregional recurrences did not occur in children who received radiotherapy to the site of the primary tumour. Ifosfamide-based chemotherapy does not reduce the incidence of loco-regional recurrence in children who do not receive local therapy.

Recently, custom-made 3D-printed prostheses have been introduced for limb salvage surgery in adult patients, but their use has not been described in pediatric patients. A series of 11 pediatric patients (mean age 10.8 years; range 2–13) with skeletal tumors treated with custom-made implants for the reconstruction of bony defects is described. Patients were followed up every 3 months. Functional results were evaluated by the Musculoskeletal Tumor Society Score (MSTS) for upper and lower limbs. The mean follow-up was 25.7 months (range 14–44). Three patients died after a mean of 19.3 months postoperatively—two because of disease progression and the other from a previous malignancy. Three patients experienced complications related to soft tissues. One patient required device removal, debridement, and antibiotic pearls for postoperative infection. Partial osseointegration between grafts and host bone was observed within a mean of 4 months. At the final follow-up, mean MSTS score was 75%. 3D prostheses may yield biological advantages due to possible integration with the host bone and also through the use of vascularized flaps. Further research is warranted.

Abstract PURPOSE Meningiomas are the most commonly diagnosed primary intracranial tumor. Resection and single-fraction radiosurgery are treatment options with well-established long-term outcomes data. Multisession radiosurgery is an alternative treatment option with promising early results. However, mature outcomes literature does not yet exist. In this study, we report our institution’s interim results on the efficacy and safety of 5-fraction radiosurgery alone for radiographically diagnosed meningiomas. MATERIALS AND METHODS Between 2005-2015 all patients who completed treatment on a single institution protocol utilizing 5-fraction robotic radiosurgery alone for the treatment of progressing radiographically diagnosed meningiomas were eligible for inclusion. Local control was calculated using the Kaplan-Meier Method. RESULTS Forty-four consecutive predominately female patients (84%) ranging in age from 33-85 (median: 59) were included in the present study. Median tumor volume was 4.05mm3 (range: 0.94-15.4mm3) and the majority of tumors were located at the base of skull (66%). A median dose of 25Gy (range: 25Gy-35Gy), was delivered to a median isodose line of 82%, (range: 70%-90%) over a median of 7 days (range: 5-11 days). Acute toxicity was minimal with 7 patients (15%) requiring a short course of steroids for symptomatic edema during treatment. Of 16 patients who presented with a cranial nerve deficit, symptom improvement was noted in 11 patients (69%). No permanent treatment related toxicity was noted in our cohort. The median radiographic follow-up was 6.9 years (range: 0.5-14.8 years). The 5 and 8-year local control rates were 100% and 95%. The median time to local failure (n=2) in our cohort was 8.2 years. CONCLUSIONS The treatment of radiographically diagnosed meningiomas with 5-fraction robotic radiosurgery provides excellent local control to date, with low rates of acute and late toxicity. However, with late failures noted in our series, continued follow-up is needed to determine the optimal dose required for long-term tumor control.

Background Limb-sparing treatment of extremity soft tissue sarcomas requires wide resections and radiation therapy. The resulting complex composite defects necessitate reconstructions using either muscle or fasciocutaneous flaps, often in irradiated wound beds. Methods A retrospective chart review was performed of all limb-sparing soft tissue sarcoma resections requiring immediate flap reconstruction from 2012 through 2016. Results Forty-four patients with 51 flaps were identified: 25 fasciocutaneous and 26 muscle-based flaps. Mean defect size, radiation treatment, and follow-up length were similar between groups. More often, muscle-based flaps were performed in younger patients and in the lower extremity. Seventeen flaps were exposed to neoadjuvant radiation, 12 to adjuvant radiation, 5 to both, and 17 to no radiation therapy. Regardless of radiation treatment, complication rates were comparable, with 28% in fasciocutaneous and 31% in muscle-based groups (p < 0.775). Muscle-based flaps performed within 6 weeks of undergoing radiotherapy were less likely to result in complications than those performed after greater than 6 weeks (p < 0.048). At time of follow-up, Musculoskeletal Tumor Society scores for fasciocutaneous and muscle-based reconstructions, with or without radiation, showed no significant differences between groups (mean [SD]: 91% [8%] vs. 89% [13%]). Conclusion The similar complication rates and functional outcomes in this study support the safety and efficacy of both fasciocutaneous flaps and muscle-based flaps in reconstructing limb-sparing sarcoma resection defects, with or without radiotherapy.
