Abstract
PURPOSE Craniospinal axis (CSA)-derived malignant peripheral nerve sheath tumors (MPNSTs) are exceedingly rare neoplasms. There is a lack of real-world cohort-based studies comprehensively reviewing the characteristics of such site-specific tumors. METHODS Clinical and pathological data were retrospectively collected. Next-generation whole exon sequencing (WES) was performed to map the genomic landscapes, comparing the mutational patterns between MPNSTs arising in the CSA versus extra CSA. Data for extra-CSA MPNSTs were sourced from public databases. RESULTS A total of 90 CSA MPNST patients, with a median age of 41.5 years, were included. Most cases (74.4%) developed sporadically, and more than half of the lesions were located intracranially, with the most frequent involvement in CN VIII (11.1%). Histologically, the median Ki-67 was 30%, and 48.9% of tumors were high-grade. The median progression-free survival (PFS) and overall survival (OS) were 17 and 19.5 months, respectively. Subgroup analysis demonstrated significant differences in the clinical, pathological, and prognostic features between the different etiological conditions and tumor sites. Multivariate analysis showed that communicating growth manner, multiple lesions and high-grade classification were independently associated with reduced PFS, while histological grade was independent prognostic factors for OS. WES analysis showed that TTN (61%) was the most recurrently mutated gene. After adjustment for confounders, the SCN1A variant was identified to have an independent association with relapses. Compared with extra-CSA MPNSTs, the CSA MPNSTs showed distinct mutational landscapes. CONCLUSION Our findings provide evidence-based insights into the specialized management of the CSA MPNST and genetically suggest the possibility of independent entity.

Abstract
BACKGROUND Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas that pose significant challenges in surgical management. This study aims to examine the anatomic distribution of MPNSTs, analyze survival rates and predictive factors for survival, and investigate the prevalence of neuropathic pain in patients who have undergone MPNST resection. PATIENTS AND METHODS A retrospective analysis of 119 patients who underwent MPNST resection was conducted. Additionally, a cross-sectional survey was administered and completed by 39 surviving patients to assess neuropathic pain prevalence using the NRS (0-10 scale) and the s-DN4 questionnaire, and quality of life (QoL) using the EQ-5D-5L index (0-1 scale). RESULTS MPNSTs most commonly occurred in the lower extremity (42.9%), followed by the upper extremity (21.0%), trunk (19.3%), head and neck (11.8%), and pelvis (5.0%). Female sex (OR: 0.25, 95% CI: 0.10-0.61) and absence of metastases (OR: 0.15, 95% CI: 0.05-0.52) were significantly associated with lower odds of mortality. Among survey respondents, 82.1% reported neuropathic pain following MPNST resection. The patients reported a mean EQ-5D-5L index score of 0.566 (± 0.253) as compared with an EQ-5D-5L of 0.851 (± 0.205) for the US general population. CONCLUSIONS The high prevalence of neuropathic pain following MPNST resection and its significant impact on QoL highlights the need for improved pain management strategies. Nerve-sparing and/or nerve-reconstructive techniques during or after tumor resection should be considered. Future research should focus on identifying risk factors for neuropathic pain development and evaluating the efficacy of preventive measures to improve long-term pain outcomes for surviving patients with MPNST.

CANCER DIAGNOSIS & PROGNOSIS 2025; 5:244-254. [PMID: 40034962 PMCID: PMC11871862 DOI: 10.21873/cdp.10436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/20/2024] [Revised: 12/09/2024] [Accepted: 12/10/2024] [Indexed: 03/05/2025]
Abstract
Background/Aim Neurofibromatosis type 1 (NF1) is an autosomal dominant hereditary tumor predisposition syndrome. In approximately 30% of cases, plexiform neurofibromas (PNFs) are identified, which are precursor lesions for malignant peripheral nerve sheath tumors (MPNSTs). MPNST is a major cause of the reduced life expectancy of NF1 patients. Case Report The patient, a two-year-old at the time of surgical treatment, had been diagnosed with an orbital nerve sheath tumor causing lid swelling and ptosis since birth. The tumor showed disproportionately rapid growth, leading to increasing functional (mechanical) restrictions in lid elevation. Surgical exploration of the orbit indicated a PNF with areas of a MPNST. Two months later, a new biopsy confirmed the MPNST. The tumor was treated with multimodal chemotherapy. After completion of chemotherapy, orbital exenteration was performed. The tissue specimens only comprised tissue of a benign PNF. However, within six months, the patient developed an intracranial recurrence and died from a rapidly growing intracerebral tumor fraction, which histologically proved to be a MPNST. Conclusion Orbital PNF is a rare and characteristic manifestation of facial NF1. Typically, tumors in this localization are associated with severe functional disabilities and aesthetic disfigurement, resulting from invasive tumor growth and skeletal deformities. Histological classification of the tumors may be challenging due to varying histological differentiation in different tumor locations. Thus, early diagnosis with representative tumor sampling and complete histological work-up of the specimen together with multimodal therapy are essential prerequisites to overcome the poor prognosis of these tumors.

Abstract
Malignant peripheral nerve sheath tumors (MPNST) are uncommon aggressive neoplasms, frequently associated with type I neurofibromatosis. This is the first case of intradural lumbar spine MPNST with intraoperative findings of associated subarachnoid hemorrhage (SAH). A 72-year-old man presented to the emergency department with severe acute low back pain. Neurological examination was unremarkable. Gadolinium-enhanced MRI of the lumbar spine showed an irregularly shaped intradural lesion extending from L3 to L5. The lesion exhibited a medium signal both on T1 and T2-weighted imaging with peripheral enhancement. Through an L3-L5 laminectomy, a diffuse SAH, and a tumor tightly adherent to cauda equina nerve roots were found. Specimen examination revealed a fusocelular tumor with pleomorphic and hyperchromatic nuclei, positive for S100, and SOX10. On an 8-month follow-up, he had no neurological deficit, with a Karnofsky performance score of 90 points. Surgical evidence of SAH in lumbar spine intradural MPNST is a novel finding.

Abstract
Microenvironmental contributions to soft tissue sarcoma progression are relatively undefined, particularly during sarcoma onset. Use of animal models to reveal these contributions is impeded by difficulties in discriminating between microenvironmental, precancerous, and cancer cells, and challenges in defining a precancerous microenvironment. We developed a zebrafish model that allows segregation of microenvironmental, precancerous, and cancerous cell populations by fluorescence-activated cell sorting. This model has high predilection for malignant peripheral nerve sheath tumor (MPNST), a type of soft tissue sarcoma that exhibits rapid, aggressive growth. Using RNA-seq, we profiled the transcriptomes of microenvironmental, precancerous, and cancer cells from our zebrafish MPNST model. We show broad activation of inflammation/immune-associated signaling networks, describe gene expression patterns that uniquely characterize the transition from precancerous to cancer ME, and identify macrophages as potential contributors to microenvironmental phenotypes. We identify conserved gene expression changes and candidate genes of interest by comparative genomics analysis of MPNST versus benign lesions in both humans and zebrafish. Finally, we functionally validate a candidate extracellular matrix protein, periostin (POSTN), in human MPNST. This work provides insight into how the microenvironment may regulate MPNST initiation and progression.

Abstract
Neurofibromatosis type 1 (NF1) significantly increases the risk of malignant peripheral nerve sheath tumors (MPNST), a rare and aggressive malignancy for which treatment is clinically challenging. This paper presents the case of a 24-year-old male with an NF1 who developed MPNST with lung metastases. Due to the limited effectiveness of systemic therapy in the treatment of MPNST, the patient underwent radical surgical resection and radiotherapy. Pathological evaluation confirmed high-grade MPNST, and PET-CT imaging revealed further metastatic progression. The treatment results for our patient are compared with those of other patients with NF1 who also developed MPNST with lung metastases in the literature. The findings suggest the need for further research into personalized treatment strategies that may improve prognosis and overall survival in patients with NF1 and MPNST, with immunotherapy being a promising therapeutic option.

Abstract
BACKGROUND Malignant peripheral sheath tumor (MPNST) is a rare, aggressive form of soft-tissue sarcoma that presents a unique set of diagnostic and treatment challenges and is associated with major unmet treatment medical needs. OBJECTIVE The chief aim of this review is to consider the epidemiology, histology, anatomic distribution, pathologic signaling pathways, diagnosis, and management of MPNST, with a focus on potential targeted therapies. A subordinate objective was to establish benchmarks for the antitumor activity of such treatments. RESULTS MPNST has an incidence of 1:100,000 in the general population and 1:3500 among patients with the inherited condition of neurofibromatosis-1. Spindle-cell sarcomas of neural-crest origin, MPNSTs are frequently situated in the extremities and pelvis/trunk, often at the confluence of large nerve roots and bundles. Highly copy-number aberrant and enriched in chromosome 8, MPNSTs have a complex molecular pathogenesis that likely involves the interplay of multiple signaling pathways, including Ras/AKT/mTOR/MAPK, EGFR, p53, PTEN, and PRC2, as well as factors in the tumor microenvironment. A combination of magnetic resonance imaging (MRI) and positron emission tomography with 18F-fluorodeoxyglucose (FDG-PET) enables comprehensive assessment of both morphology and metabolism, while MRI- and ultrasound-guided core needle biopsy can confirm histopathology. Although surgery with wide excisional margins is now the chief curative approach to localized disease, MPNST-specific survival has not improved in decades. For advanced and metastatic MPNST, radiation and chemotherapy (chiefly with anthracyclines plus ifosfamide) have somewhat promising but still largely uncertain treatment roles, chiefly in local control, downstaging, and palliation. No single druggable target has emerged, no objective responses have been observed with a number of targeted therapies (cumulative disease control rate in our review = 22.9-34.8%), and combinatorial approaches directed toward multiple signal transduction mechanisms are hallmarks of ongoing clinical trials. CONCLUSIONS Despite advances in our understanding of the genetics and molecular biology of MPNST, further research is warranted to: (1) unravel the complex pathogenesis of this condition; (2) improve diagnostic yield; (3) delineate the appropriate roles of chemotherapy and radiation; and (4) develop a targeted therapy (or combination of such treatments) that is well tolerated and prolongs survival.

Abstract
Objective Peripheral nerve tumors (PNTs) are rare diseases. So far, no multicenter data on diagnostics, the efficacy of treatment, long-term outcomes, and health-related quality of life (HRQoL) exist. The establishment of the Peripheral Nerve Tumor Registry (PNTR) in 2015 allows for the systematic analysis of patients with tumors associated with peripheral nerves. The present study aims to investigate the impact of PNT on an individual's HRQoL and the effect of surgery. Methods HRQoL was pre- and postoperatively assessed by the Euro-Qol-5D-5L (EQ-5D-5L) and Euro-Qol visual analog scale (EQ-VAS) survey in the retrospective and prospective study arm in three active participating study centers. An index was calculated based on the EQ-5D-5L for the quantification of health state (0: worst possible state of health, 1: best possible state of health). The EQ-VAS ranges from 0% (worst imaginable health status) to 100% (best possible health status). Patient characteristics (age, sex), as well as disease (histopathological entity) and treatment (pre- and postoperative symptoms, type of treatment)-specific data, were analyzed. Results Data from 171 patients from three high-volume centers were included, with schwannoma (70.8%, n = 121) and neurofibroma (15.8%, n = 27) being the most prevalent histopathological diagnoses. Both the median health index value (preoperative: 0.887, n = 167; postoperative: 0.910, n = 166) and the median EQ-VAS (preoperative: 75%, n = 167; postoperative: 85%, n = 166) of the entire cohort regarding all histopathological diagnosis improved significantly after surgical therapy (p < 0.001). Preoperatively, 12.3% (n = 21) reached the highest index score of 1.0 in EQ-5D-5L and 100% in the EQ-VAS score in 5.3% (n = 9) of all patients. Postoperatively, the highest index score of 1.0 and 100% in the EQ-VAS score increased significantly and were achieved in 33.3% (n = 57) and 11.1% (n = 19) of the patients, respectively (p < 0.001). Conclusion For the first time, our study presents multicenter data on life quality and the effect of surgery in primarily benign peripheral nerve tumors. Early surgery at a specialized center could improve neurological outcomes and, in conclusion, better QoL. In summary, surgical therapy significantly improved the entire cohort's QoL, VAS, and analgesia.

Abstract
BACKGROUND Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas which commonly arise from neurofibromatosis type 1. Lung metastases of the tumors are well-known, but intraoperative cerebral tumor embolisms of MPNSTs have not been reported in literature. CASE PRESENTATION A 52-year-old female patient with neurofibromatosis type 1 underwent a right lung partial resection for lung tumors. She was extubated after adequate recovery of spontaneous breathing; however, she could not respond to verbal commands. In the intensive care unit, her neurological examination revealed conjugate eye deviation, right hemiparalysis, and aphasia. Magnetic resonance imaging revealed acute cerebral ischemia, so she underwent an endovascular thrombectomy. The histopathological diagnosis of emboli was a MPNST, which was identical with that of the resected lung tumor. CONCLUSION We report the first case of delayed emergence caused by a cerebral tumor embolism of MPNST during partial lung resection.

Abstract
Background. Peripheral nerve sheath malignancies (PNSM) are a rare and aggressive group of sarcomas that can occur sporadically, after radiation therapy, or related to neurofibromatosis type 1. Loss of function of NF1, TP53, and CDKN2A genes is thought to contribute to the progression of benign neurofibroma to PNSM and is a poor prognostic sign. The optimal management of patients with this disease is currently unresolved, and specific prognostic factors have not been established.
Aim. To analyze the results of surgical treatment in patients with PNSM and establish prognostic factors of overall and recurrence-free survival rate.
Materials and methods. The retrospective and prospective studies enrolled adult patients with histologically confirmed PNSM treated between 1998 and 2021 at the N.N. Blokhin National Medical Research Center for Oncology. Surgical intervention was performed on 61 patients, 38 (62%) females and 23 (38%) males. The most common PNSM localization was paravertebral (22 [36%] patients), followed by retroperitoneal (14 [23%] patients), and upper and lower extremities (13 [21%] and 12 [20%] patients, respectively).
Results. For PNSM patients with a history of surgery, the median overall survival (OS) was 46 months (95% confidence interval 26.165.9). The 3-year and 5-year OS was 46% and 31%, respectively. The median recurrence-free survival (RFS) was 27 months (8.745.3), and 3-year and 5-year RFS was 26% and 13%, respectively. Median OS for grade 1 malignancies was not achieved, while grade 2 and grade 3 malignancy was 53 and 33 months, respectively (p=0.033). The median RFS for grade 1, 2, and 3 tumors was 119, 43, and 15 months, respectively (p=0.078). Patients who underwent radical (R0) surgery had higher RFS (p=0.006) and OS (p0.0001). After radical (R0) surgery, the median OS was not achieved; after nonradical (R1/R2) surgery, the median was 34 months. The median RFS was 124 months after R0-resection and 48 months after R1/R2.
Conclusion. The most significant prognostic factors in PNSM patients are the radicality of the surgery performed and the malignancy grade. In our study, tumor size and localization did not affect the long-term treatment results.

The Role of Socioeconomic Status and Race/Ethnicity in Malignant Peripheral Nerve Sheath Tumor Survival: A Surveillance, Epidemiology, and End Results-Based Analysis. Cancer Epidemiol Biomarkers Prev 2022; 31:1830-1838. [PMID: 35437584 PMCID: PMC9444868 DOI: 10.1158/1055-9965.epi-21-0997] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 10/25/2021] [Accepted: 03/17/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Recent investigations of malignant peripheral nerve sheath tumor (MPNST) survival have reported higher mortality among non-White individuals. However, previous analyses have not examined the impact of socioeconomic status (SES) on these observations. This study aims to characterize factors associated with cause-specific MPNST survival, including information related to census-tract-level SES (CT-SES). METHODS We identified 2,432 primary MPNSTs using the Surveillance, Epidemiology, and End Results (SEER) 18 (2000-2016) database. We used Cox proportional hazards modeling to estimate the effects of sex, race/ethnicity, CT-SES quintile, metastasis at diagnosis, tumor site, age at diagnosis, and treatment by surgery on survival. Models were fit in both the full population and, separately, stratified by race/ethnicity and age at diagnosis (<40 vs. ≥40). RESULTS In adjusted models, age at diagnosis, CT-SES, and metastasis at diagnosis were associated with mortality. In race/ethnicity-stratified analysis, higher CT-SES was found to improve survival only in the White population. Among those diagnosed before age 40, metastasis at diagnosis and American Indian/Alaska Native race/ethnicity were associated with mortality, and both Hispanic ethnicity and Asian/Pacific Islander race were suggestive for increased mortality. Among cases, diagnoses at age 40 and above, age at diagnosis, male sex, and CT-SES were associated with mortality. CONCLUSIONS This analysis provides evidence that among pediatric and young adult patients, non-White populations experience inferior survival compared with Whites, independent of CT-SES. Our findings also suggest that the effect of CT-SES on MPNST survival may differ by racial/ethnic group. IMPACT These findings suggest that barriers to healthcare for certain racial/ethnic groups extend beyond SES.

Epidemiology, Characteristic, and Prognostic Factors of Primary Sporadic Intradural Malignant Peripheral Nerve Sheath Tumor in the Spinal Canal: A Systematic Literature Review. Front Oncol 2022; 12:911043. [PMID: 35898898 PMCID: PMC9309257 DOI: 10.3389/fonc.2022.911043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 06/13/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose Primary sporadic intradural malignant peripheral nerve sheath tumor (MPNST) in the spinal canal is a type of rare neoplasm with challenging diagnosis and therapy. The overall prognosis of this tumor is markedly different from that of the usual spinal intradural tumors. The purpose of this systematic review is to reduce the misdiagnosis and enhance the prognosis of the disease by reviewing the literature. Methods PubMed, Medline, and Embase databases were searched for articles in English language published from 1980 to May 2021, yielding 500 potentially relevant articles. The keywords were as follows: “spinal”, “malignant peripheral nerve sheath tumor”, “neurosarcoma”, “malignant schwannoma”, and “malignant neurofibroma”. Thirteen papers met the eligibility criteria, including 55 cases with spinal intradural primary sporadic MPNSTs, which were confirmed by post-operation pathology. We further analyzed the clinical manifestations, radiological manifestations, pathological features, comprehensive treatment strategies, and prognosis. Results Fifty-five spinal intradural primary sporadic MPNSTs from 30 (54.5%) male and 25 (45.5%) female patients with an average age at diagnosis of 40 years (range, 3–70 years) were included in the study. The most common clinical manifestations were local or radicular pain and motor disturbance. All tumors had significant enhancement and heterogeneous enhancement was more common. Out of 18 lesions, 14 were diagnosed as high grade and the remaining 4 were diagnosed as low grade. The ki-67 labeling index ranged from 5% to 60%. The median recurrence and survival time were 36 and 72 months, respectively. The log-rank tests indicated that significant predictors of OS were patient age (≤30 vs. >30 years) at the time of diagnosis and the presence of metastatic disease, and similar analyses for RFS demonstrated that the presence of metastatic disease was the only significant predictor (60 vs. 10 months). The multivariate Cox proportional hazards regression analysis revealed that absence of metastasis was an independent factor for predicting a favorable prognosis. Conclusions Spinal intradural primary sporadic MPNSTs are challenging malignant tumors without a systematic treatment plan. The factors affecting its prognosis are not clear. Even after surgical treatment and adjuvant treatment, the recurrence rate and mortality rate are still high. Clinicians should be alert to the possibility of this disease and achieve early detection and treatment.

Abstract
Objective To delineate a distinct clinical, pathological, cytoimmunohistochemical distinguishing features of extracranial parotid neurogenic tumors. Pleomorphic adenoma, the most common parotid neoplasm by itself can mimic a neurogenic tumor, i.e., schwannoma. We have reported such rare entity in earlier publications. This is a systematic review with a case discussion of the third only documented malignant peripheral nerve sheath tumor (MPNST) arising in the parotid in a noncontiguous fashion. We review the management, diagnostic immunohistochemistry of this low-grade sarcoma, which has not been documented thus far. Purpose Significant diagnostic and management pitfalls may occur even with fine-needle aspiration or biopsy, as they will not be ideal in diagnosis of parotid neurogenic neoplasms preoperatively. Ultrasound as well as magnetic resonance imaging may not offer a specific facial nerve course in association to the neoplastic lesion. Majority of the neurogenic tumors can be misdiagnosed and hence, improperly managed leading to facial nerve injury and tumor morbidity. Due to the lack of ideal diagnostic modality and morbidity of facial nerve injury, a thorough review of differential diagnosis inclusive of neurogenic tumors of the parotid is to be considered in indications of surgical approaches. We retrospectively review successful resection with preservation of facial nerve function in our parotid neurogenic tumors. Conclusion The objective of this paper is to review the guidelines and treatment planning of parotid neurogenic tumors.

Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue malignancies that can occur in any part of the body. The most common sites are the proximal limbs and trunk. Intracranial MPNSTs are rare; most originate from the auditory, trigeminal, and other cranial nerves, and occurrence within the brain parenchyma is rarer. Here, we describe a malignant peripheral schwannoma in the cerebellar hemisphere of the brain parenchyma. To our knowledge, this is the first case of brain parenchymal metastasis of an MPNST. We observed no effects on the tumor after the application of multiple chemotherapy drugs; thereafter, we explored the literature surrounding the condition.

Abstract
Background Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas with dismal prognosis. Pathological and genetic markers may predict more aggressive behavior in MPNSTs but have uncommonly been investigated, and few are used in daily practice. This study reviews the prognostic value of immunohistochemical markers and genetic alterations in MPNST. Methods A systematic search was performed in PubMed and Embase databases according to the PRISMA guidelines. Search terms related to ‘MPNST’ and ‘prognostic’ were used. Studies investigating the association of immunohistochemical markers or genetic alterations with prognosis were included. Qualitative synthesis was performed on all studies. A distinction was made between univariable and multivariable associations. Results Forty-six studies were included after full-text screening. Sixty-seven different immunohistochemical markers were investigated. Absence of S100 and H3K27me3 and high Ki67 and p53 staining was most commonly independently associated with worse survival and disease-free survival. Several genetic alterations were investigated as well with varying association to survival. TP53, CDK4, RASSF1A alterations were independently associated with worse survival, as well as changes in chromosomal length in Xp, 10q, and 16p. Conclusions MPNSTs harbor complex and heterogeneous biology. Immunohistochemical markers and genetic alterations have variable prognostic value. Absence of S100 and H3K27me3 and increased Ki67 can be of prognostic value. Alterations in TP53 or increase in p53 staining may distinguish MPNSTs with worse outcomes. Genetic alterations and staining of other cell cycle regulatory and Ras pathway proteins may also help stratifying patients with worse outcomes. A combination of markers can increase the prognostic value.

Abstract
Background Malignant peripheral nerve sheath tumor (MPNST) is an aggressive and poorly understood malignant neoplasm. Even in the setting of multimodal therapy, the clinical course of MPNST is frequently marked by metastatic conversion and poor overall prognosis, with optimal treatment paradigms for this rare tumor unknown. Methods We reviewed the medical records and histopathology of 54 consecutive patients who were treated at University of California San Francisco between 1990 and 2018. Results Our cohort consisted of 24 male and 30 female patients (median age 38 years). Fédération Nationale des Centres de Lutte Contre Le Cancer (FNCLCC) sarcoma grading criteria segregated patients into groups with differences in overall survival (OS) (P = .02). Increasing Ki-67 labeling index was associated with poor OS (hazard ratio [HR] 1.36 per 10%, P = .0002). Unsupervised hierarchical clustering-based immunohistochemical staining patterns identified 2 subgroups of tumors with differences in H3K27me3, Neurofibromin, S100, SOX10, p16, and EGFR immunoreactivity. In our cohort, cluster status was associated with improved locoregional failure-free rate (P = .004) in response to radiation. Conclusions Our results lend support to the FNCLCC sarcoma grading criteria as a prognostic scheme for MPNST, although few cases of grade 1 were included. Further, we identify increased Ki-67 labeling as a strong predictor of poor OS from MPNST. Finally, we identify a subset of MPNSTs with a predictive immunohistochemical profile that has improved local control with adjuvant radiotherapy. These data provide insights into the grading and therapy for patients with MPNST, although further studies are needed for independent validation.

Abstract
BACKGROUND Malignant peripheral nerve sheath tumors (MPNST) are rare and aggressive non-rhabdomyoblastic soft-tissue sarcomas (NRSTS) in children. This study set out to investigate clinical presentation, treatment modalities, and factors associated with survival in pediatric MPNST using Dutch nationwide databases. METHODS Data were obtained from the Netherlands Cancer Registry (NCR) and the Dutch Pathology Database (PALGA) from 1989 to 2017. All primary MPNSTs were collected. Demographic differences were analyzed between adult and pediatric (age ≤18 years) MPNST. In children, demographic and treatment differences between neurofibromatosis type 1 (NF1) and non-NF1 were analyzed. A Cox proportional hazard model was constructed for localized pediatric MPNSTs. RESULTS A total of 70/784 MPNST patients were children (37.1% NF1). Children did not present differently from adults. In NF1 children, tumor size was more commonly large (> 5 cm, 92.3% vs 59.1%). Localized disease was primarily resected in 90.6%, and radiotherapy was administered in 37.5%. Non-NF1 children tended to receive chemotherapy more commonly (39.5% vs 26.9%). Overall, estimated five-year survival rates of localized NF1-MPNST was 52.4% (SE: 10.1%) compared with 75.8% (SE: 7.1%) in non-NF1 patients. The multivariate model showed worse survival in NF1 patients (HR: 2.98; 95% CI, 1.17-7.60, P = 0.02) and increased survival in patients diagnosed after 2005 (HR: 0.20; 95% CI, 0.06-0.69, P = 0.01). No treatment factors were independently associated with survival. CONCLUSION Pediatric MPNSTs have presentations similar to adult MPNSTs. In children, NF1 patients present with larger tumors, but are treated similarly to non-NF1 MPNSTs. In localized pediatric MPNST, NF1 is associated with worse survival. Promisingly, survival has increased for pediatric MPNSTs after 2005.

Oncological Treatment Considerations Differ across Surgical Subspecialties Treating Malignant Peripheral Nerve Sheath Tumors: An International Survey. Sarcoma 2020; 2020:6406439.

Abstract
Background Malignant peripheral nerve sheath tumors (MPNSTs) are rare and aggressive soft tissue sarcomas (STS) that, because of their origin, are operated by several surgical subspecialties. This may cause differences in oncologic treatment recommendations based on presentation. This study investigated these differences both within and between subspecialties. Methods A survey was distributed among several (inter)national surgical societies. Differences within and between subspecialties were analyzed by χ2-tests. Results In total, 30 surgical oncologists, 30 neurosurgeons, 85 plastic surgeons, and 29 “others” filled out the survey. Annual caseload, tumor sites operated, and fellowship training differed significantly between subspecialties. While most surgeons agreed upon preoperative use of MRI, the use of radiological staging and FDG-PET use differed between subspecialties. Surgical oncologists agreed upon core needle biopsies as an ideal type of biopsy while other subspecialties differed in opinion. On average, 53% of surgeons always consider preservation of function preoperatively, but 42% would never perform less extensive resections for function preservation. Respondents agreed that radiotherapy should be considered in tumor sizes >10 cm, microscopic, and macroscopic positive margins. A preferred sequence of radiotherapy administration differed between subspecialties. There was no consensus on indications and sequence of administration of chemotherapy in localized disease. Conclusion Surgical oncologists generally agree on preoperative diagnostics; other subspecialties do not. Considering the preservation of function differed among all subspecialties. Surgeons do agree on some indications for radiotherapy, yet the use of chemotherapy in localized MPNSTs lacks consensus. A preferred sequence of multimodal therapy differs between and within surgical subspecialties, but surgical oncologists prefer neoadjuvant radiotherapy.

Abstract
BACKGROUND Malignant peripheral nerve sheath tumors (MPNSTs) are rare yet highly aggressive soft tissue sarcomas. Children with neurofibromatosis type 1 (NF1) have a 10% lifetime risk for development of MPNST. Prognosis remains poor and survival seems worse for NF1 patients. METHODS This narrative review highlights current practices and pitfalls in the management of MPNST in pediatric NF1 patients. RESULTS Preoperative diagnostics can be challenging, but PET scans have shown to be useful tools. More recently, functional MRI holds promise as well. Surgery remains the mainstay treatment for these patients, but careful planning is needed to minimize postoperative morbidity. Functional reconstructions can play a role in improving functional status. Radiotherapy can be administered to enhance local control in selected cases, but care should be taken to minimize radiation effects as well as reduce the risk of secondary malignancies. The exact role of chemotherapy has yet to be determined. Reports on the efficacy of chemotherapy vary as some report lower effects in NF1 populations. Promisingly, survival seems to ameliorate in the last few decades and response rates of chemotherapy may increase in NF1 populations when administering it as part of standard of care. However, in metastasized disease, response rates remain poor. New systemic therapies are therefore desperately warranted and multiple trials are currently investigating the role of drugs. Targeted drugs are nevertheless not yet included in first line treatment. CONCLUSION Both research and clinical efforts benefit from multidisciplinary approaches with international collaborations in this rare malignancy.
