RESUMEN
BACKGROUND AND OBJECTIVES: The optimal timing between preoperative embolization of hypervascular metastatic bone lesions and surgery has yet to be established. Our analysis sought to evaluate embolization timing impacts blood loss, transfusion risk, and operative time in patients with hypervascular primary tumors. METHODS: We identified patients with renal cell (RCC) or thyroid carcinoma undergoing surgery between 1992 and 2023. Patients were segregated into the following cohorts: (1) no embolization preoperatively, (2) surgery <24 h of embolization, and (3) surgery >24 h after embolization. Multivariate logistic regression analyses were performed to assess the effect of embolization timing while controlling for confounding variables. RESULTS: No differences were seen in all evaluated outcomes between immediate and delayed embolization cohorts. No differences in estimated blood loss were seen between the immediate (OR: 0.685, 95% CI: 0.159-2.949; p = 0.611) and delayed (OR: 0.568, 95% CI: 0.093-3.462; p = 0.539) surgery cohorts compared with patients without embolization. Surgery >24 h after embolization was not associated with a higher risk of prolonged operative time (OR: 13.499, 95% CI: 0.832-219.146; p = 0.067). CONCLUSIONS: These findings suggest that surgery may be safely delayed beyond 24 h from embolization without a higher risk of bleeding. In appropriately selected cohorts, embolization may not be needed preoperatively.

Patient-reported outcomes (PRO) are collected directly from the patient and have become increasingly utilized in the clinical setting and in clinical research. In musculoskeletal oncology patients, a number of patient-reported outcomes measures (PROM) have been developed and investigated to evaluate functional outcomes and health-related quality of life in these patients. With the growing evidence for PROM in musculoskeletal oncology patients, PROM should be considered for the clinical care of these patients.

BACKGROUND: Pathologic fractures of the pelvis/sacrum due to metastatic bone disease (MBD) cause pain and dysfunction due to mechanical instability of the pelvic ring. This study presents our multi-institutional experience with percutaneous stabilization of pathologic fractures and osteolytic lesions from MBD throughout the pelvic ring. METHODS: The records of patients undergoing this procedure from 2018 to 2022 were reviewed retrospectively from two institutions. Surgical data and functional outcomes were recorded. RESULTS: Fifty-six patients underwent percutaneous stabilization, with a median operative duration of 119 min (interquartile range [IQR]: 92.8, 167) and median estimated blood loss of 50 mL (IQR: 20, 100). The median length of stay was 3 days (IQR: 1, 6), and 69.6% (n = 39) of patients were discharged home. Early complications included one partial lumbosacral plexus injury, three acute kidney injuries, and one case of intra-articular cement extravasation. Late complications included two infections and one revision stabilization procedure for hardware failure. Mean Eastern Cooperative Oncology Group (ECOG) scores improved from 3.02 (SD 0.8) preoperatively to 1.86 (SD 1.1) postoperatively (p < 0.001). Ambulatory status also improved (p < 0.001). CONCLUSIONS: Percutaneous stabilization of pathologic fractures and osteolytic defects of the pelvis and sacrum is a procedure that improves patient function, ambulatory status and is associated with a limited complication profile.

Radiolucent implants in have demonstrated promising results for both extremity and spine oncologic procedures. However, questions persist about whether the superiority in surveillance imaging justify the increased cost and technical challenges. In this review, we present the current body of literature for the use of radiolucent implants in musculoskeletal oncology, with a focus on implant complications, including screw loosening, breakage, malposition, and loss of reduction. We also discuss clinical outcomes, technical considerations, and postoperative radiotherapy.

OBJECTIVE: Radiotherapy is an important component of soft tissue sarcoma management. Radiation osteitis is a common radiographic finding identified in the setting of radiotherapy on magnetic resonance imaging (MRI). This study aims to identify the incidence of radiation osteitis in patients who received radiotherapy for soft tissue sarcoma and if a further workup, including a biopsy, was performed for concerning MRI findings. MATERIALS AND METHODS: Medical records of patients with soft tissue sarcoma who received radiotherapy from 2008 to 2020 were retrospectively reviewed. Patients with at least one MRI of the sarcoma site following radiotherapy and information regarding radiotherapy treatments were included. MRIs of these patients were reviewed for the presence of radiation osteitis by two musculoskeletal radiologists. The clinical course of these patients including biopsy for concerning MRI findings, local recurrence, and metastasis was recorded. RESULTS: Thirty soft tissue sarcoma patients who received radiation for soft tissue sarcoma were included. Radiation osteitis was present in 18 patients. The time to osteitis present on MRI following radiotherapy completion was a median of 4.5 months. Biopsy for concerning MRI findings was performed in eight patients, five for local recurrence, and three for regional osseous metastasis. Three patients had confirmed osseous metastases. CONCLUSION: Although radiation osteitis is often a benign imaging finding, it can be difficult to discern these lesions from potentially malignant sites of disease. We recommend multidisciplinary management of soft tissue sarcoma at sarcoma centers to appropriately identify benign from malignant lesions and decide the necessity of a biopsy.

BACKGROUND: This investigation compared outcomes of patients with undifferentiated pleomorphic sarcoma of soft tissue (UPS-S) to UPS of bone (UPS-B). METHODS: The Surveillance, Epidemiology, and End Results database was reviewed from 1975-2016. Disease-specific survival (DSS) was estimated using Kaplan-Meier, and a multivariable Cox regression model identified factors prognostic of DSS. The UPS-S cohort consisted of 4529 patients and the UPS-B cohort consisted of 200 patients. The smaller UPS-B cohort was bootstrapped to create a size-matched cohort of 4500 patients. RESULTS: The median age of patients with UPS-S was 67 (54;78) y compared to 55 (40;69) y for UPS-B patients (P < 0.001). For UPS-S, the median DSS was 317 mo compared to 70 for UPS-B (P = 0.020). On multivariable analysis for UPS-S, age (HR, 1.018; 95% CI, 1.01-1.03; P < 0.001), non-extremity tumors (HR, 1.490; 95% CI 1.14-1.95; P = 0.004), and AJCC Stage III (HR, 2.238; 95% CI 1.2-4.17; P = 0.011), and Stage IV (HR, 9.388; 95% CI 4.69-18.79; P < 0.001) disease were negative prognostic factors, while surgery (HR 0.234; 95% CI, 0.16-0.34; P < 0.001) was a positive prognostic factor. For UPS-B, tumor size > 8 cm (HR, 3.101; 95% CI, 1.09-8.75; P = 0.033) was the only prognostic factor identified. CONCLUSIONS: The current study found a strong association between surgery and survival for UPS-B patients on a univariable analysis, but no treatment type was associated with survival in a multivariable model. Further research is needed to reliably inform the optimal treatment of these patients.

BACKGROUND AND OBJECTIVES: Positron emission tomography-computerized tomography (PET-CTs) are becoming increasingly utilized in sarcoma care, workup, and surveillance. This study aimed to describe additional PET-CT findings as well as subsequent workups and changes in the clinical course due to those results. METHODS: Patient records were retrospectively reviewed, and the additional workups and evaluations triggered by PET-CT findings were qualitatively analyzed to document their results. Additional changes in the clinical course were documented. RESULTS: A total of 183 bone and soft tissue sarcoma patients underwent PET-CT as part of staging or surveillance. Additional workup was performed in 31.5% (n = 41 of 130) patients who had positive PET-CT findings. Among these, 36.6% (n = 15 of 41) patients had clinically significant findings that altered the clinical course. Overall, 14.8% (n = 27 of 183) experienced a change in the clinical course due to PET-CT. CONCLUSION: PET-CT often highlights lesions of potential clinical importance. Additional workup, as well as changes in the clinical course, were not infrequent. Future, multi-institutional studies should address the value of PET-CT in sarcoma care.

Background: Sarcomas are a rare and heterogeneous tumor group composed of a variety of histologic subtypes. Targeted next-generation sequencing (NGS) of bone and soft tissue sarcomas is a nascent field with limited evidence for its use within clinical practice. Therefore, further research is needed to validate NGS in sarcoma and assess the clinical utility of these techniques with the hope of improving treatment options.Methods: Comprehensive molecular profiling with NGS was performed on 136 tumors (116 soft tissue, 20 bone) using two commercial vendors. Patient records were retrospectively reviewed, and the clinical impact of NGS-related findings were qualitatively analyzed to determine actionable mutations and number of changes in treatment.Results: The median age was 55.0 years (IQR 42-67 years), and most patients were non-metastatic at presentation (80.9%, n = 110). Prior to performing NGS, 72.1% (n = 98) were treated with a mean 1.1 ± 1.2 lines of systemic chemotherapy. NGS identified 341 putative alterations with at least one mutation present in 89.7% (n = 122) of samples. In a subset of 111 patients with available TMB data, 78.7% (n = 107) had a low (<6 m/Mb) mutational burden. Among all 136 cases, 47.1% (n = 64) contained clinically actionable alterations, and 12 patients had a change in medical treatment based on NGS. Those who underwent a treatment change all had metastatic or recurrent disease; three of these patients experienced a clinical benefit.Conclusion: Most bone and soft tissue sarcomas harbor at least one genetic alteration, and it appears a sizeable number of tumors contain mutations that are clinically actionable. While a change in treatment based off NGS-related findings occurred in 12 cases, three patients experienced a clinical benefit. Our data provide further proof-of-concept for NGS in sarcoma and suggest a clinical benefit may be observed in select patients.

All orthopaedic surgeons during the course of their career will likely encounter both benign and malignant musculoskeletal neoplasms. Given the rarity of these entities and the stress conferred by diagnosing a tumor or tumorlike condition, many orthopaedic surgeons may benefit from a review of the contemporary treatment of such patients. Whether in the outpatient clinic or following a high-energy trauma, special attention should be given to concerning signs and symptoms that will aid in the workup of children and adults with a possible tumor. A thorough and logical workup in this manner will often lead to a definitive diagnosis such as metastatic bone disease or perhaps a benign lesion. In these instances, the informed general orthopaedic surgeon or subspecialist may choose to treat the patient independently. However, if the workup is inconclusive or if the diagnosis is even questionably malignant, referral to an orthopaedic oncologist should be sought as to avoid pitfalls in diagnosis and treatment.

BACKGROUND: Proximal femoral replacement (PFR) is reserved as a salvage procedure after failed total hip arthroplasty (THA) or after wide margin resection of tumors involving the proximal femur. Although failure of the PFR construct remains a significant problem, indication has not previously been investigated as a risk factor for failure. METHODS: This study retrospectively evaluated patients who underwent PFR over a consecutive 15-year period for primary sarcoma or metastatic disease of the proximal femur, compared with conversion to PFR after failed THA. PFR failure was defined as recurrent prosthetic dislocations, periprosthetic fracture, aseptic loosening, or infection that ultimately resulted in revision surgery. RESULTS: Overall, 99 patients were evaluated, including 58 in the neoplasm and 41 in the failed THA cohorts. Failed THA patients were older (P < .001), with a greater proportion having comorbid hypertension (P = .008), cardiac disease (P = .014), and history of prior ipsilateral and intracapsular surgeries (P < .001). The failure rate was significantly higher in failed THA patients (39.0% vs 10.3%; P < .001) with significantly shorter implant survivorship on Kaplan-Meier analysis (P = .003). A multivariate Cox proportional hazards model showed that THA failure was the only independent predictor for PFR failure (hazard ratio: 4.26, 95% confidence interval: 1.66-10.94; P = .003). CONCLUSION: This study revealed significantly worse PFR implant survivorship in patients undergoing PFR for the indication of failed THA compared with neoplasm. Although the underlying etiology of this relationship remains to be explicitly outlined, poor bone quality and soft tissue integrity, multiple prior surgeries, and comorbid conditions are likely contributing factors.

Soft tissue sarcomas (STS) are a rare and highly heterogeneous group of solid tumors, originating from various types of connective tissue. Complete removal of STS by surgery is challenging due to the anatomical location of the tumor, which results in tumor recurrence. Additionally, current polychemotherapeutic regimens are highly toxic with no rational survival benefit. Cold atmospheric plasma (CAP) is a novel technology that has demonstrated immense cancer therapeutic potential. Canady Cold Helios Plasma (CHCP) is a device that sprays CAP along the surgical margins to eradicate residual cancer cells after tumor resection. This preliminary study was conducted in vitro prior to in vivo testing in a humanitarian compassionate use case study and an FDA-approved phase 1 clinical trial (IDE G190165). In this study, the authors evaluate the efficacy of CHCP across multiple STS cell lines. CHCP treatment reduced the viability of four different STS cell lines (i.e., fibrosarcoma, synovial sarcoma, rhabdomyosarcoma, and liposarcoma) in a dose-dependent manner by inhibiting proliferation, disrupting cell cycle, and inducing apoptosis-like cell death.

BACKGROUND: Soft tissue sarcomas (STSs) are mesenchymal tumors that may rarely metastasize to lymph nodes. This investigation sought to evaluate regional lymph node metastasis (RLNM) in extremity STS using a national cohort. MATERIALS AND METHODS: This study was a retrospective review of the Surveillance, Epidemiology, and End Results database from 1975 to 2016. A Cox proportional hazards model was used to identify prognostic factors associated with disease-specific survival (DSS). RESULTS: RLNM was present in 3.7% (n = 547) of extremity STS. The rate of RLNM was highest in rhabdomyosarcoma (26.7%), clear cell sarcoma (18.8%), epithelioid sarcoma (14.5%), angiosarcoma (8.1%), spindle cell sarcoma (5.0%), and synovial sarcoma (3.2%). The 5-year DSS probability without RLNM was 69% (standard error: 1.3%) compared to 26% (standard error: 3.6%) with RLNM (P < 0.001). For the historically high-risk extremity STS, advanced age (hazard ratio (HR), 1.036; 95% confidence interval (CI), 1.0-1.04; P < 0.001), higher grade tumors (HR, 1.979; 95% CI, 1.3-3.0; P < 0.001), tumor size greater than 10 cm (HR, 1.892; 95% CI, 1.3-2.7; P < 0.001), primary site surgery (HR, 0.529; 95% CI, 0.3-0.8; P = 0.006), distant metastasis (HR, 4.585; 95% CI, 3.0-6.8; P < 0.001), and RLNM (HR, 2.153; 95% CI, 1.3-3.5; P = 0.003) were each independent disease-specific prognostic factors. CONCLUSIONS: The prognosis of RLNM in historically high-risk extremity STS is poor with a 5-year DSS of 26%. These data support a staging system of STS inclusive of nodal involvement and contribute to the growing body of evidence that characterizes the rates of RLNM in STS.

BACKGROUNDS AND OBJECTIVES: This investigation sought to describe the outcomes of primary leiomyosarcoma of bone (PLB) compared to soft tissue leiomyosarcoma (SLMS). METHODS: This was a review of the Surveillance, Epidemiology, and End Results database from 1975 to 2016. Kaplan-Meier methods were used to estimate disease-specific survival (DSS), and a Cox regression model was used to identify prognostic factors. RESULTS: Of the 7502 identifiable cases, 1% (n = 74) were PLB and 99% (n = 7428) were SLMS. Survival was the same between PLB and SLMS (p = .209). On multivariable analysis for high-grade SLMS, radiation (neoadjuvant: hazard ratio [HR], 0.56; 95% confidence interval [CI], 0.4-0.8; p = .003; adjuvant: HR, 0.75; 95% CI, 0.6-0.9; p = .008) and surgery (procedure specific) improved DSS. For PLB, wide resection/limb salvage (HR, 0.40; 95% CI, 0.3-0.5; p = .018) and amputation (HR, 0.69; 95% CI, 0.5-0.9; p < .001) were positive prognostic factors. Neither radiation nor chemotherapy were prognostic factors for survival in PLB. CONCLUSIONS: For SLMS, radiation portends a survival advantage. For PLB, however, neither chemotherapy nor radiation were significant prognostic factors, which suggests the optimal treatment for PLB, similar to other primary soft tissue sarcomas originating in bone, remains an unmet medical need.

BACKGROUNDS AND OBJECTIVES: Lymphovascular invasion (LVI) has shown evidence of an association with worse survival in high-grade osteosarcoma patients. The purpose of this investigation was to prognosticate LVI as a predictor of survival. METHODS: This was a retrospective review of high-grade, localized osteosarcoma patients over a consecutive 10-year period. Proportional hazards regression was used to identify prognostic factors. Cumulative mortality incidence was estimated with recurrence as a competing risk. RESULTS: Forty-two cases with a median follow-up of 64 months (range, 6-158 months) were reviewed. LVI was present in 21.4% (n = 9) cases. The five- and ten-year survivals in LVI (+) were 40% and 20%, compared to 93% and 81% in LVI (-), respectively (p < .001). After controlling for confounders, advanced age (hazards ratio [HR], 1.134; 95% confidence interval [CI], 1-1.2; p = .01) and LVI (HR, 21.768; 95% CI, 3-135; p = .001) were negative prognosticators. The cumulative incidence of recurrence was no different between LVI (+) and LVI (-) (p = .811), though the incidence of mortality was significantly higher in LVI (+) (p = .003). CONCLUSION: The presence of LVI in the setting of high-grade, localized osteosarcoma is associated with greater rates of mortality and appears to portend a dismal prognosis.

Ganglion cysts are benign soft tissue tumors that often occur adjacent to joints or tendons. We report a case of an elbow joint ganglion cyst in a patient who presented with a painful, progressive elbow contracture. The patient was successfully treated with resection of the subbrachialis ganglion cyst combined with an anterior capsular release and an ulnar nerve decompression to recover elbow motion. This case highlights the value of advanced imaging in patients presenting with an atraumatic, painful, and progressive elbow contracture.

BACKGROUND AND OBJECTIVES: Internal hemipelvectomy is a complex procedure used to treat malignancy that involves the pelvis. Reconstruction of the pelvis after type I or type I/IV resection remains controversial due to high complication rates and debatable functional benefit. Modern reconstruction options may provide a rapid, intuitive, and reliable way to reconstitute the pelvic ring. METHODS: This is a retrospective case series of four patients who underwent a novel reconstruction method involving computer navigation and segmental spinal instrumentation applied to the pelvis after type I or type I/IV pelvic resection for malignancy between 2015 and 2020. RESULTS: Time to ambulation postoperatively ranged from 1 to 7 days, and median length of hospital stay was 8.5 (7.5, 10.5) days. Complications included wound necrosis in two patients that did not require reoperation and wound infection in one patient that required irrigation and debridement. There was no radiographic evidence of hardware loosening or failure on follow-up. Three patients remain alive and two remain disease-free. At most recent follow-up, all patients were able to ambulate and perform activities of daily living. CONCLUSIONS: The technique for pelvic reconstruction described allows for rapid fixation intraoperatively with few complications and satisfactory functional results in this limited series.

BACKGROUND: The prevalence of metastatic bone disease (MBD) grows each year as treatments improve. Little has been published about functional and pain outcomes in this group after surgery. Patient-Reported Outcomes Measurement Information System (PROMIS® ) can collect information, in just minutes, about patient's physical, mental, and social health. This study evaluated PROMIS® pain and functional scores in surgically treated patients with MBD. METHODS: Basic demographics and PROMIS® scores were recorded from a total of 13 patients at 9 periods of time over 6 months. RESULTS: The average change in physical function at week 1 was -2.5 (standard deviation [SD] = 5.4), at 2 weeks 1.7 (SD = 7.6), after 4 weeks 6.9 (SD = 10), after 6 weeks 6.4 (SD = 10.9), after 10 weeks 15.3 (SD = 3.1), and after 3 months 8.6 (SD = 7.6). The average change in pain inference at week 1 was -1.2 (SD = 7.3), at 2 weeks -2.1 (SD = 9.5), after 4 weeks -12.6 (SD = 4.5), after 6 weeks -8.3 (SD = 10.2), after 10 weeks -16.6 (SD = 4.3), and after 3 months -11.4 (SD = 8.2). CONCLUSIONS: PROMIS® provides a feasible means to collect data in this population. Trends of improved function and decreased pain were seen after surgery. Continuing this study will hopefully elucidate more insight into the surgical treatment of MBD.

BACKGROUND: Metastatic bone disease is a substantial burden to patients and the healthcare system as a whole. Metastatic disease can be painful, is associated with decreased survival, and is emotionally traumatic to patients when they discover their disease has progressed. In the United States, more than 250,000 patients have metastatic bone disease, with an estimated annual cost of USD 12 billion. Prior studies suggest that patients who receive prophylactic fixation for impending pathologic fractures, compared with those treated for realized pathologic fractures, have decreased pain levels, faster postoperative rehabilitation, and less in-hospital morbidity. However, to our knowledge, the relative economic utility of these treatment options has not been examined. QUESTIONS/PURPOSES: We asked: (1) Is there a cost difference between a cohort of patients treated surgically for pathologic fractures compared with a cohort of patients treated prophylactically for impending pathologic lesions? (2) Do these cohorts differ in other ways regarding their utilization of healthcare resources? METHODS: We performed a retrospective study of 40 patients treated our institution. Between 2011 and 2014, we treated 46 patients surgically for metastatic lesions of long bones. Of those, 19 (48%) presented with pathologic fractures; the other 21 patients (53%) underwent surgery for impending fractures. Risk of impending fracture was determined by one surgeon based on appearance of the lesion, subjective symptoms of the patient, cortical involvement, and location of the lesion. At 1 year postoperative, four patients in each group had died. Six patients (13%) were treated for metastatic disease but were excluded from the retrospective data because of a change in medical record system and inability to obtain financial records. Variables of interest included total and direct costs per episode of care, days of hospitalization, discharge disposition, 1-year postoperative mortality, and descriptive demographic data. All costs were expressed as a cost ratio between the two cohorts, and total differences between the groups, as required per medical center regulations. All data were collected by one author and the medical center's financial office. RESULTS: Mean total cost was higher in patients with pathologic fractures (cost unit [CU], 642 ± 519) than those treated prophylactically without fractures (CU, 370 ± 171; mean difference, 272; 95% CI, 19-525; p = 0.036). In USD, this translates to a mean of nearly USD 21,000 less for prophylactic surgery. Mean direct cost was 41% higher (nearly USD 12,000) in patients with a pathologic fracture (CU, 382 ± 300 versus 227 ± 93; mean difference, 155; 95% CI, 9-300; p = 0.038). Mean length of stay was longer in patients with pathologic fractures compared with the group treated prophylactically (8 ± 6 versus 4 ± 3 days; mean difference, 4; 95% CI, 1-7; p = 0.01). CONCLUSIONS: These findings show economic and clinical value of prophylactic stabilization of metastatic lesions when performed for patients with painful lesions compromising the structural integrity of long bones. Patients sustaining a pathologic fracture may represent a more severe, sicker demographic than patients treated for impending pathologic lesions. LEVEL OF EVIDENCE: Level IV, economic and decision analysis.

Introduction: Nodular fasciitis is a rare, benign soft tissue lesion that can prove to be difficult to diagnose, especially when intra-articular. Case presentation: A 17-year-old female softball player presents with several year history of right knee pain and swelling initially attributed to patellar maltracking refractory to non-operative and operative management. Management and Outcomes: Initial pathology suggested tenosynovial giant cell tumor; however, further tissue diagnosis revealed nodular fasciitis, which was eventually resected. Conclusion: Intra-articular nodular fasciitis of the knee is rare and may easily be misdiagnosed due to its nonspecific clinical presentation. Careful histological examination can aid in diagnosis. Nodular fasciitis should be considered in the differential diagnoses for intra-articular lesions of the knee joint.
RESUMEN
CASE: A 40-year-old man was evaluated for a painful mass on his right calf, and a 36-year-old woman presented with a painless mass on her right foot. Final pathology revealed marked nuclear atypia and positivity for S100/SOX10 and AE1/AE3 confirming diagnoses of myoepithelial carcinoma. Both patients underwent surgical resection and are without evidence of local recurrence or metastatic disease at 1-year follow-up. CONCLUSION: Soft-tissue tumors presenting in the extremities warrant careful evaluation and timely histopathologic diagnosis. Myoepithelial carcinomas are rare, aggressive tumors with a propensity for local recurrence and metastasis. Treatment of these tumors should be discussed by a multidisciplinary tumor team.
