Ewing sarcoma among children 5 years of age or younger: Is it a different disease? Pediatr Blood Cancer 2024:e31268. [PMID: 39138616 DOI: 10.1002/pbc.31268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 07/19/2024] [Accepted: 07/30/2024] [Indexed: 08/15/2024]
Abstract
INTRODUCTION Children ≤5 years of age with Ewing's sarcoma (ES) possibly have a distinct disease biology, data on which are scarce. We evaluated clinical features, outcomes, and prognostic factors of ES among children with age ≤5 years. METHODS Children with ES registered between 2003 and 2019 were included. Baseline clinical and treatment details were retrieved from medical records. Prognostic factors were identified using multivariable Cox regression. Clinical features and outcomes of children ≤5 years were compared with those greater than 5 years by chi-square and log-rank tests. Propensity score-matched (PSM) analysis was done to evaluate the impact of age on survival in the metastatic and localized subgroups. RESULTS Out of the 859 patients, 86 (10%) were ≤5 years of age (median age 4 years, 60 males [69.8%]). The most common location was the extremities (37.2%), followed by thorax (27.9%) and head and neck (H&N) (22.1%); baseline metastases were seen in 25 patients (29.8%). The median event-free-survival (EFS) and overall survival (OS) were 25.6 and 68.7 months, respectively. Metastatic disease predicted inferior OS (hazard ratio [HR] = 2.54, p = .018) and EFS (HR = 2.47, p = .007], symptom duration ≤3 months predicted an inferior OS (HR = 2.17, p = .048). Compared to age greater than 5 years, younger children had more H&N and less pelvic primaries (p < .001) and lesser baseline metastases (p = .037). PSM analysis did not reveal any significant impact of age on OS in the metastatic (HR = 1.59, p = .29) or localized cohort (HR = 1.77, p = .09). CONCLUSIONS Children with ES ≤5 years of age have a distinct favorable clinical presentation. However, age is not an independent prognostic factor for survival outcomes when adjusted for confounders.

Abstract
Ewing sarcoma (ES) of the spine is a rare childhood cancer with sparse literature on treatment outcomes. We aimed to describe survival outcomes and prognostic factors in patients with spinal ES treated at a single institute in a resource-challenged setting. We conducted a retrospective analysis of patients with spinal ES registered at a tertiary care oncology center between 2003-2019. Clinical patient data was retrieved from hospital records. Cox regression analysis was used to identify the association of baseline clinical parameters with event free survival (EFS) and overall survival (OS). A cohort of 85 patients was analyzed including 38 (45%) patients with metastatic disease. The median age was 15 years with 73% being male. Local therapy was administered in 62 (72.9%) patients with surgery alone in 8 (9.4%), radiotherapy alone in 36 (42.4%) and both in 18 (21.2%) patients. A higher proportion of males received local therapy than females (80.3% versus 59.1%; p = 0.049). The median EFS and OS were 20.1 and 28.6 months, respectively. On univariable analysis, age ≤ 15 years, female sex, serum albumin ≤3.5 g/dL and hemoglobin ≤11 g/dL were associated with inferior EFS while younger age, female sex, hypoalbuminemia and metastatic disease were associated with inferior OS. On multivariable analysis, only hypoalbuminemia was predictive for inferior EFS (HR:2.41; p = 0.005) while hypoalbuminemia (HR:2.06;p = 0.033) and female sex (HR:1.83; p = 0.046) were associated with inferior OS. We concluded that hypoalbuminemia confers poor prognosis in ES spine. Survival outcomes are poorer in females treated in our setting, possibly due to prevailing sex-based biases.

Abstract
Ewing's sarcoma family of tumors (EWSFT) is common in the second decade of life. Achieving good outcomes in EWSFT requires a multimodality approach. We report the clinico-pathological features, treatment, and survival outcomes of patients with EWSFT treated at our center. Patients diagnosed and treated for EWSFT at our center from 2009-2017 were included in this study. Data was collected from the patient's case records. Event-free survival (EFS) and overall survival (OS) were estimated using the Kaplan-Meier method. The study included 173 patients among whom 44 (25%) patients were metastatic at diagnosis. The median age of patients was 16 years. The most common site of the primary tumor was the pelvis (16.1%), followed by long bones. The median follow-up was 75 months and the 5-year EFS and OS were 43.7% and 45.1% respectively for the overall cohort whereas for the localized disease were 56.6% and 57.2% respectively. Metastatic disease, tumor volume > 200 ml, tumor diameter > 8 cm, pelvic site, hemoglobin < 10 gms%, elevated lactate dehydrogenase, positive margin, and necrosis less than 90% were significantly associated with inferior OS on univariate analysis. On multivariate analysis, metastasis disease, tumor diameter > 8 cm, and necrosis < 90% were significantly associated with inferior OS. Large tumors, advanced disease, and poor response to chemotherapy are associated with poor outcomes in EWSFT. Whether the use of dose-dense chemotherapy and/or autologous stem cell transplant would improve outcomes without increased toxicity in resource-limited settings needs to be explored.

Determinants and impact of diagnostic interval in bone sarcomas: A retrospective cohort study. Pediatr Blood Cancer 2023; 70:e30135. [PMID: 36524611 DOI: 10.1002/pbc.30135] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 10/30/2022] [Accepted: 11/14/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Diagnostic delays in cancers are frequent in developing countries due to poor health infrastructure. Existing literature from developed countries suggests that diagnostic interval in bone sarcomas is primarily dictated by tumour biology with no impact on survival. This study evaluates the social and biological determinants of the diagnostic interval in bone sarcomas in a resource-challenged setting and assesses its impact on treatment outcomes. METHODS A retrospective single-institutional study was conducted on patients with high-grade bone sarcomas recorded in the sarcoma clinic database between 2003 and 2018. Baseline clinical characteristics and treatment outcomes were recorded. Logistic regression was performed to assess the impact of baseline clinical and social characteristics (distance from treating centre and rural vs. urban residence) on the diagnostic interval. Further, the impact of diagnostic interval on histologic response to neoadjuvant chemotherapy, amputation requirement in extremity sarcomas and survival was evaluated. RESULTS A total of 1227 patients were included for analysis. The median diagnostic interval was 4 months (3-7 months). Age above 18 years, Ewing sarcoma (ES) diagnosis, absence of fever at presentation and tumour size above 7.5 cm were predictors of a longer diagnostic interval (>4 months). The length of the diagnostic interval did not impact amputation requirement or survival outcomes. However, the proportion of patients with good necrosis post-neoadjuvant chemotherapy was lower among patients with longer diagnostic intervals (25% vs. 34·16%; p-value = .04). CONCLUSION Tumour characteristics rather than social factors determined the diagnostic interval. Diagnostic interval did not impact survival outcomes even in a resource-constrained setting.

Front Oncol 2023; 13:1148480. [PMID: 37188186 PMCID: PMC10175811 DOI: 10.3389/fonc.2023.1148480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 04/05/2023] [Indexed: 05/17/2023] Open
Abstract
Introduction The outcomes of osteosarcoma in low middle income countries (LMICs) are different due to patients presenting in advanced stages, resource constraints and the use of non-high-dose-methotrexate (HDMTX)-based regimens. This study derived and validated a prognostic score for osteosarcoma that integrates biologic and social factors and is tailored for patients from an LMIC setting using a non-HDMTX-based protocol. Materials and methods A retrospective study including osteosarcoma patients enrolled for treatment at a single tertiary care centre in India between 2003-19 was conducted. Baseline biologic and social characteristics were extracted from medical records and survival outcomes were noted. The cohort was randomised into a derivation and validation cohort. Multivariable Cox regression was used to identify baseline characteristics that were independently prognostic for survival outcomes in the derivation cohort. A score was derived from the prognostic factors identified in the derivation cohort and further validated in the validation cohort with estimation of its predictive ability. Results 594 patients with osteosarcoma were eligible for inclusion in the study. Around one-third of the cohort had metastatic disease with 59% of the patients residing in rural areas. The presence of metastases at baseline (HR 3.39; p<0.001; score=3), elevated serum alkaline phosphatase (SAP) >450 IU/L (HR 1.57; p=0.001; score=1) and baseline tumour size > 10 cm (HR 1.68; p<0.001; score=1) were identified to be independent factors predicting inferior event free survival (EFS) and were included in development of the prognostic score. Patients were categorized as low risk (score 0), intermediate risk (score 1-3) and high risk (4-5). Harrell's c-indices for the score were 0.682, 0.608 and 0.657 respectively for EFS in the derivation, validation and whole cohort respectively. The timed AUC of ROC was 0.67 for predicting 18-month EFS in the derivation, validation and whole cohorts while that for 36-month EFS were 0.68, 0.66 and 0.68 respectively. Conclusions The study describes the outcomes among osteosarcoma patients from an LMIC treated uniformly with a non-HDMTX-based protocol. Tumor size, baseline metastases and SAP were prognostic factors used to derive a score with good predictive value for survival outcomes. Social factors did not emerge as determinants of survival.

C-Reactive Protein Pretreatment-Level Evaluation for Ewing's Sarcoma Prognosis Assessment-A 15-Year Retrospective Single-Centre Study. Cancers (Basel) 2022; 14:cancers14235898.

Abstract
Background: A pathological/inflamed cellular microenvironment state is an additional risk factor for any cancer type. The importance of a chronic inflammation state in most diffuse types of tumour has already been analysed, except for in Ewing’s sarcoma. It is a highly malignant blue round cell tumour, with 90% of cases occurring in patients aged between 5 and 25 years. Worldwide, 2.9 out of 1,000,000 children per year are affected by this malignancy. The aim of this retrospective study was to analyse the role of C-reactive protein (CRP) as a prognostic factor for Ewing’s sarcomas. Methods: This retrospective study at Klinikum rechts der Isar included 82 patients with a confirmed Ewing’s sarcoma diagnosis treated between 2004 and 2019. Preoperative CRP determination was assessed in mg/dL with a normal value established as below 0.5 mg/dL. Disease-free survival time was calculated as the time between the initial diagnosis and an event such as local recurrence or metastasis. Follow-up status was described as death of disease (DOD), no evidence of disease (NED) or alive with disease (AWD). The exclusion criteria of this study included insufficient laboratory values and a lack of information regarding the follow-up status or non-oncological resection. Results: Serum CRP levels were significantly different in patients with a poorer prognosis (DOD) and in patients who presented distant metastasis (p = 0.0016 and p = 0.009, respectively), whereas CRP levels were not significantly different in patients with local recurrence (p = 0.02). The optimal breakpoint that predicted prognosis was 0.5 mg/dL, with a sensitivity of 0.76 and a specificity of 0.74 (AUC 0.81). Univariate CRP analysis level >0.5 mg/dL revealed a hazard ratio of 9.5 (95% CI 3.5−25.5). Conclusions: In Ewing’s sarcoma cases, we consider a CRP pretreatment value >0.5 mg/dL as a sensitive prognostic risk factor indication for distant metastasis and poor prognosis. Further research with more data is required to determine more sensitive cutoff levels.

Abstract
ES treatment requires a multidisciplinary approach. Deficiencies in treatment affect the results negatively. This study showed that carboplatin can be used effectively as an alternative to actinomycin-D in the consolidation treatment. In addition, the presence of metastasis at diagnosis, tumor originating from the soft tissue, advanced stage and progressive disease are the poor prognostic factors in ES.
Background Treatment of Ewing sarcoma (ES) requires multidisciplinary approach and deficiencies in treatment adversely affect the results. This study included patients diagnosed with ES and aimed to determine the factors affecting prognosis and investigate the efficacy of replacing actinomycin-D with carboplatin in consolidation treatment. Methods Eighty-two pediatric ES patients diagnosed at a single institution between 2005 and 2020 were retrospectively evaluated. Clinical and epidemiological features, treatment modalities, prognostic criteria, and overall survival (OS) rates of patients revieved. In consolidation treatment, 22 patients were treated with actinomycin-D and 32 patients with carboplatin (500 mg/m2/dose), 24 patients could not receive consolidation treatment. The 5- and 10-year OS rates of the patients were compared. Results The 5- and 10-year OS rates of the 82 patients with ES were 46% and 40%, respectively. The 5-year OS rates in the group with localized disease (n = 55) and metastasis (n = 27) at diagnosis were 54% and 26%, respectively (p = 0.006). When evaluated according to the consolidation treatment administered both the 5- and 10-year OS rates of the patients receiving actinomycin-D were 50%. The 5-year OS rate was 58% in the carboplatin group, and the 5- and 10-year OS rates of patients that did not receive consolidation treatment was 20%. Conclusions Survival was significantly worse in the group that did not receive consolidation treatment. Furthermore, our results suggested that carboplatin could be used effectively as an alternative to actinomycin-D in ES consolidation treatment.

Abstract
Background This study aims to predict the lymphatic metastasis in Ewing's sarcoma (ES) patients by nomogram. The risk of lymphatic metastasis in patients with ES was predicted by the built model, which provided guidance for the clinical diagnosis and treatment planning. Methods A total of 929 patients diagnosed with ES were enrolled from the year of 2010 to 2016 in the Surveillance, Epidemiology, and End Results (SEER) database. The nomogram was established to determine predictive factors of lymphatic metastasis according to univariate and multivariate logistic regression analysis. The validation of the model performed using multicenter data (n = 51). Receiver operating characteristics (ROC) curves and calibration plots were used to evaluate the prediction accuracy of the nomogram. Decision curve analysis (DCA) was implemented to illustrate the practicability of the nomogram clinical application. Based on the nomogram, we established a web calculator to visualize the risk of lymphatic metastases. We further plotted Kaplan-Meier overall survival (OS) curves to compare the survival time of patients with and without lymphatic metastasis. Results In this study, the nomogram was established based on six significant factors (survival time, race, T stage, M stage, surgery, and lung metastasis), which were identified for lymphatic metastasis in ES patients. The model showed significant diagnostic accuracy with the value of the area under the curve (AUC) was 0.743 (95%CI: 0.714–0.771) for SEER internal validation and 0.763 (95%CI: 0.623–0.871) for multicenter data external validation. The calibration plot and DCA indicated that the model had vital clinical application value. Conclusion In this study, we constructed and developed a nomogram with risk factors to predict lymphatic metastasis in ES patients and validated accuracy of itself. We found T stage (Tx OR = 2.540, 95%CI = 1.433–4.503, P < 0.01), M stage (M1, OR = 2.061, 95%CI = 1.189–3.573, P < 0.05) and survival time (OR = 0.982, 95%CI = 0.972–0.992, P < 0.001) were important independent factors for lymphatic metastasis in ES patients. Furthermore, survival time in patients with lymphatic metastasis or unclear situation (P < 0.0001) was significantly lower. It can help clinicians make better decisions to provide more accurate prognosis and treatment for ES patients.

Bosma SE, van der Heijden L, Sierrasesúmaga L, Merks HJHM, Haveman LM, van de Sande MAJ, San-Julián M. What Do We Know about Survival in Skeletally Premature Children Aged 0 to 10 Years with Ewing Sarcoma? A Multicenter 10-Year Follow-Up Study in 60 Patients. Cancers (Basel) 2022; 14:cancers14061456. [PMID: 35326609 PMCID: PMC8946787 DOI: 10.3390/cancers14061456] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 03/08/2022] [Accepted: 03/10/2022] [Indexed: 02/06/2023] Open
Abstract
(1) Background: Younger age has been associated with better overall survival (OS) in Ewing sarcoma (ES), especially under the age of 10. The favorable survival in younger patients underlines the need for minimizing treatment burden and late sequelae. Our study aimed at describing clinical characteristics, treatment and outcome of a cohort of ES patients aged 0−10. (2) Methods: In this retrospective multicenter study, all consecutive ES patients aged 0−10, treated in four sarcoma centers in the Netherlands (n = 33) and one in Spain (n = 27) between 1982 and 2008, with a minimum follow-up of 10 years, were included. OS, local recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) were calculated. Potential factors of influence on OS (risk and protective factors) were analyzed. (3) Results: 60 patients with median follow-up 13.03 years were included. All patients were treated with chemotherapy in combination with local treatment, being surgery alone in 30 (50%) patients, radiotherapy (RT) alone in 12 (20%) patients or surgery plus RT in 18 (30%) patients (12 pre- and 6 postoperative). Limb salvage was achieved in 93% of patients. The 10-OS, -LRFS and -DMFS are 81% (95% CI: 71−91%), 89% (95% CI: 85−93%) and 81% (95% CI: 71−91%), respectively. Six patients developed LR, of which two developed subsequent DM; all had axial ES (pelvis, spine or chest wall), and these patients all died. Ten patients developed DM; eight died due to progressive disease, and two are currently in remission, both with pulmonary metastasis only. Negative or wide resection margin was significantly associated with better OS. Age < 6 years, tumor volume < 200 mL, absence of metastatic disease and treatment after 2000 showed trends towards better OS. Two patients developed secondary malignancy; both had chemotherapy combined with definitive RT for local treatment. (4) Conclusions: Overall survival of these youngest patients with ES was very good. Limb salvage surgery was achieved in >90% of patients. Wide resection margin was the only factor significantly associated with better survival.

Abstract
Ewing sarcoma is one of the most common types of malignant bone tumor in children and adolescents. However, to our limited knowledge, no study exists that uses machine learning to create algorithms for the prediction of survivorship for Ewing sarcoma. About 2332 patients with Ewing sarcoma between 1975 and 2016 in the United States were identified from Surveillance, Epidemiology, and End Results (SEER) program. All patients in the data set were randomly assigned into the training set and the testing set, at a 2:8 ratio. In the training set, boosted decision tree, support vector machine, nonparametric random forest method, and neural network models were developed to predict the 5-year survivorship. The overall survival rate in 5-year follow-up of this patient cohort is 60.72%. With respect to the algorithms for both cancer specific survival and overall survival, there was slight superiority in our performance metrics favoring the random forest method over the other models for survival prediction, with 77/83% sensitivity and 91/94% specificity, respectively. The random forest method was incorporated into a freely available web-based application. This application can be accessed through https://zryan.shinyapps.io/EwingSarcoma/. Clinical Significance: To the best of our knowledge, this is the first available predictive model for predicting survival in Ewing sarcoma based on machine-learning algorithms. This study may provide orthopedic surgeons with an easily accessible prediction tool when dealing with patients suffering from Ewing sarcoma.

Outcomes with nondose-dense chemotherapy for Ewing sarcoma: A practical approach for the developing world. Pediatr Blood Cancer 2020; 67:e28604. [PMID: 32706522 DOI: 10.1002/pbc.28604] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 06/17/2020] [Accepted: 07/05/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND The current multidisciplinary approach in the treatment of Ewing sarcoma has improved cure rates, with contemporary dose-dense chemotherapy attaining 5-year event-free survival (EFS) of 73% in localized cases. Dose-intense and dose-dense chemotherapy is difficult in the majority of resource-limited settings with limited access to optimal supportive care. We report on patients with Ewing sarcoma treated on EFT-2001, a nondose-dense chemotherapy protocol. PROCEDURE A retrospective analysis was conducted of patients (<15 years) with Ewing sarcoma treated with curative intent during January 2013-June 2017 with an institutional ethics committee-approved nondose-dense protocol (EFT-2001). Local therapy was planned after 9-12 weeks of chemotherapy with metastatic sites addressed with radiotherapy. The study assessed outcomes and prognostic factors. RESULTS We analysed 200 patients with M:F ratio of 1.27:1 and metastases in 41 patients (20.5%). At a median follow up of 41.5 months (range 4.5-81.8 months), respective 3-year EFS and overall survival (OS) of the whole cohort is 65.3% (95% confidence interval [CI]: 58.1-71.7%) and 79.3% (95% CI: 72.8-84.5%); for localized and metastatic cohort, 70.9% (95% CI: 62.9-77.5%) and 82.8% (95% CI: 75.7-89.0%); and for metastatic cohort, 42.8% (95% CI: 28.0-58.6%) and 65.3% (95% CI: 47.7-78.3%). Presence of residual disease (morphologic/metabolic) on positron emission tomography-computed tomography scan done 3 months post definitive radiotherapy (hazard ratio [HR] 7.92 [95% CI: 3.46-18.14]) and delay in any form of local control >4 months (HR 3.42 [95% CI: 1.32-8.89]) affected outcomes. Nonrelapse mortality during treatment was 6.5%, mainly due to cardiomyopathy (3.0%) and bacterial sepsis (1.5%). Cardiotoxicity was seen in 11.5% of patients. CONCLUSIONS Nondose-dense chemotherapy provides good outcomes with manageable toxicities in a multidisciplinary treatment approach, while reducing cumulative drug exposures in the developing world where dose-intense or dose-dense chemotherapy could potentially increase toxicity, and hence seems a feasible approach in resource-limited settings. Presence of any residual disease post definitive radiotherapy or delay in local control portends poor outcome.

Abstract
India has made significant improvement in childhood cancer services in last few decades. However, the outcome still remains modest as compared to global standards due to significant barriers in recognition, diagnosis and cure. Data regarding comprehensive childhood cancer burden in country is lacking due to low and urban predominant coverage of population-based cancer registry programs. The available data shows lower incidence of childhood cancer incidence especially in leukaemia and CNS tumours which may suggest poor awareness of caregivers and delayed diagnosis with many "missed cases". Incidence data are also skewed towards male preponderance which suggests gender bias in seeking healthcare. The childhood cancer services in India are predominantly restricted to few tertiary care centres in major cities. The outcome in major groups of cancer is complicated by delayed and more advanced stage of presentation and poor supportive care during intensive treatment. Treatment refusal and abandonment remains major hurdles. Last few decades saw development of dedicated paediatric oncology services and training programs in the country. The development of InPOG (Indian Paediatric Oncology group) for conducting collaborative trials will lead to adoption of uniform treatment protocols suited for the country. Financial support through the government promoted health insurance and holistic support through philanthropic organizations have improved treatment adherence and outcome. Moving forward, the focus should be on strengthening the cancer registries for capturing nationwide data, improving awareness of childhood cancer among caregivers and healthcare workers for early recognition and improving accessibility of childhood cancer care services beyond major cities.

Abstract
BACKGROUND We investigated the effects of surgical margins, histological response, and radiotherapy on local recurrence (LR), distant metastasis (DM), and survival in Ewing sarcoma. PROCEDURE Disease evolution was retrospectively studied in 982 patients with Ewing sarcoma undergoing surgery after chemotherapy using a multistate model with initial state surgery, intermediate states LR, pulmonary metastasis (DMpulm), other DM ± LR (DMother), and final state death. Effect of risk factors was estimated using Cox proportional hazard models. RESULTS The median follow-up was 7.6 years (95% CI, 7.2-8.0). Risk factors for LR are pelvic location, HR 2.04 (1.10-3.80), marginal/intralesional resection, HR 2.28 (1.25-4.16), and radiotherapy, HR 0.52 (0.28-0.95); for DMpulm the risk factors are <90% necrosis, HR 2.13 (1.13-4.00), and previous pulmonary metastasis, HR 4.90 (2.28-8.52); for DMother are 90% to 99% necrosis, HR 1.56 (1.09-2.23), <90% necrosis, HR 2.66 (1.87-3.79), previous bone/other metastasis, HR 3.08 (2.03-4.70); and risk factors for death without LR/DM are pulmonary metastasis, HR 8.08 (4.01-16.29), bone/other metastasis, HR 10.23 (4.90-21.36), and <90% necrosis, HR 6.35 (3.18-12.69). Early LR (0-24 months) negatively influences survival, HR 3.79 (1.34-10.76). Once DMpulm/DMother arise only previous bone/other metastasis remain prognostic for death, HR 1.74 (1.10-2.75). CONCLUSION Disease extent and histological response are risk factors for progression to DM or death. Tumor site and surgical margins are risk factors for LR. If disease progression occurs, previous risk factors lose their relevance. In case of isolated LR, time to recurrence is important for decision-making. Radiotherapy seems protective for LR especially in pelvic/axial. Low percentages of LR in extremity tumors and associated toxicity question the need for radiotherapy in extremity Ewing sarcoma.

Easy-to-use clinical tool for survival estimation in Ewing sarcoma at diagnosis and after surgery. Sci Rep 2019; 9:11000. [PMID: 31358784 PMCID: PMC6662666 DOI: 10.1038/s41598-019-46721-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Accepted: 07/03/2019] [Indexed: 12/12/2022] Open
Abstract
Accurate survival estimations in Ewing sarcoma are necessary to develop risk- and response adaptive treatment strategies allowing for early decision-making. We aim to develop an easy-to-use survival estimation tool from diagnosis and surgery. A retrospective study of 1314 Ewing sarcoma patients was performed. Associations between prognostic variables at diagnosis/surgery and overall survival (OS), were investigated using Kaplan-Meier and multivariate Cox models. Predictive accuracy was evaluated by cross-validation and Harrell C-statistics. Median follow-up was 7.9 years (95%CI 7.6–8.3). Independent prognostic factors at diagnosis were age, volume, primary tumor localization and disease extent. 5 risk categories (A-E) were identified with 5-year OS of 88% (86–94), 69% (64–74), 57% (50–64), 51% (42–60) and 28% (22–34) respectively. Harrell C-statistic was 0.70. Independent prognostic factors from surgery were age, volume, disease extent and histological response. In categories A-B, 5y OS increased to 92% (87–97) and 79% (71–87) respectively for 100% necrosis and decreased to 76% (67–85) and 62% (55–69) respectively for <100% necrosis. In categories C-E, 5y OS increased to 65% (55–75), 65% (52–78) and 52% (38–66) respectively for ≥90% necrosis and decreased to 38% (22–54), 11% (0–26) and 7% (0–19) respectively for <90% necrosis. We present an easy-to-use survival estimation tool from diagnosis in Ewing sarcoma based on age, volume, primary tumor localization and disease extent. Histological response is a strong additional prognostic factor for OS.

Abstract
Objective This study was designed to develop a nomogram for assessing the survival of patients with Ewing sarcoma (ES). Methods Data from patients diagnosed with ES between 2004 and 2013 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. Based on patient registration, the primary cohort was divided into a training set (n = 479, data from 17 cancer registries) and a validation set (n = 137, data from 1 cancer registry). Then, the prognostic effects of variables were analyzed using Kaplan–Meier method and Cox proportional hazard model. Moreover, nomograms were established for estimating 3- and 5-year overall survival (OS) and cancer-special survival (CSS) based on Cox regression model. Last, nomogram was validated by training set and validation set. Results According to the multivariate analysis of training set, nomogram which combined age, race, stage, tumor site, tumor size and chemotherapy was identified. The internal bootstrap resampling approach suggested the nomogram had sufficient discriminatory power with the C-index of OS: 0.754 (95% CI, 0.705–0.802) and CSS: 0.759 (95% CI, 0.700–0.800). The calibration plots also demonstrated good consistence between the prediction and the observation. Conclusion Our nomogram is a reliable and powerful tool for distinguishing and predicting the survival of ES patients, thus helping to better select medical examinations and optimize treatment options in collaboration with medical oncologists and surgeons.

Abstract
BACKGROUND AND OBJECTIVES A lack of consensus exists on the prognosis of extraskeletal Ewing sarcoma (EES) relative to its skeletal (ES) counterpart in adults. This study sought to characterize outcome differences between the two diagnoses. METHODS From 2004 to 2014, the NCDB identified 2,660 Ewing Sarcoma patients. Cox proportional hazards regression analysis was used to identify risk factors for overall survival (OS). RESULTS EES patients were older, more likely to be female, and have smaller tumors. Among patients with ES, 4.0% received no treatment, 2.5% received local therapy only (surgery and/or radiation), 16.8% received chemotherapy only, while 52.2% received combination therapy (local and chemotherapy), and 17.0% recieived triple therapy (surgery, radiation and chemotherapy). Among patients with EES, 4.3% recived no treatment, 5.6% received local therapy only, 15.6% received chemotherapy only, while 47.0% received combination therapy, and 21.6% received triple therapy. No difference in OS was observed between the two groups (P = 0.816). Factors independently associated with OS for ES included age (HR = 1.26, P = 0.01), Charlson-Deyo Score (CDS) ≥2 (HR = 3.66, P < 0.001), combination therapy (HR = 0.39, P < 0.001) and triple therapy (HR = 0.34, P < 0.001). For EES, factors for OS were age (HR = 1.52, P < 0.001), CDS ≥2 (HR = 1.90, P = 0.02), combination therapy (HR = 0.44, P < 0.001), triple therapy (HR = 0.34, P < 0.001) and PNET histology (HR = 1.33, P = 0.02). CONCLUSIONS Demographic, histological, and treatment characteristics differ between adult patients diagnosed with ES and ESS. However, survival and independent predictors of survival are consistent between the two diagnoses.

Abstract
BACKGROUND To investigate the optimal local treatment strategies for patients with non-metastatic Ewing sarcoma (ES) of bone. METHODS Patients with ES of bone were identified using the Surveillance Epidemiology and End Results database. Kaplan-Meier log-rank test and Cox regression models were performed to assess the effect of the types of local treatment strategies on cause-specific survival and overall survival. RESULTS 560 patients were included with a median age of 16 years. A total of 284, 162 and 114 patients received surgery alone, surgery and radiotherapy, and radiotherapy alone, respectively. The types of local treatment strategies had no effect on survival outcomes in multivariate analysis. In the subgroup analysis of patients with tumor diameter <8 cm, surgery ± radiotherapy had a significantly improved cause-specific survival (P = 0.039), and had potential to improve overall survival (P = 0.070) in multivariate analysis. The local treatment strategies had no effect on survival in patients with different tumor location. CONCLUSION There is no local treatment of choice for non-metastatic ES of bone in terms of survival. More well-designed studies are needed to confirm our findings and investigate the role of various local treatment strategies in relation to primary tumor diameter.

Abstract
Ewing sarcoma family tumors (ESFT) are heterogeneous, aggressive group of disease with peak incidence in adolescent and young adults. The outcome has been improved dramatically from 10% with surgery and radiotherapy alone to 65%-70% now, in localized disease, with the introduction of chemotherapy. Chemotherapy regimen evolved from single agent to multiagent with effort of many cooperative clinical trials over decades. The usual treatment protocol include introduction of multi-agent chemotherapy in neoadjuvant setting to eradicate systemic disease with timely incorporation of surgery and/or radiotherapy as local treatment modality and further adjuvant chemotherapy to prevent recurrence. Risk adapted chemotherapy in neoadjuvant and adjuvant setting along with radiotherapy has been used in many international collaborative trials and has resulted in improved outcome, more so in patients with localized disease. The role of high dose chemotherapy with stem cell rescue is still debatable. The outcome of patients with metastatic disease is dismal with long term outcome ranges from 20%-40% depending on the sites of metastasis and intensity of treatment. There is a huge unmet need to improve outcome further, more so in metastatic setting. Novel therapy targeting the molecular pathways and pathogenesis of ESFT is very much required. Here we have discussed the current standard of management in patients with ESFT, investigational targeted or novel therapies along with future promises.

Abstract
Bone sarcomas are rare tumors, approximating 0.2% of all cancers, with osteosarcoma (OGS), chondrosarcoma, and Ewing sarcoma being the most common cancers in this subset. The formation of disease management groups/clinics focused on sarcomas has resulted in better understanding and management of these uncommon tumors. Multiple large-scale retrospective data from Tata Memorial Hospital (TMH) and All India Institute of Medical Sciences have reported outcomes comparable to Western data in the field of OGS and Ewing sarcoma, with interesting prognostic factors identified for further evaluation. Soft tissue sarcomas are a rare heterogeneous group of tumors, more than 50 different tumor entities. The common subtypes identified in India include Ewing sarcoma and synovial sarcoma. Valuable work regarding brachytherapy has been done by radiation oncologists from the TMH, especially in pediatric patients.
