Building the bridge between rhabdomyosarcoma in children, adolescents and young adults: The road ahead. HHS A retrospective study of the Italian neuroblastoma registry. Survival curves were calculated using the Kaplan–Meier method.7 The log‐rank test was used to compare the survival curves of patient subgroups by univariate analysis to ascertain the potential value of prognostic factors.8, Variables with P values < 0.25 in the log‐rank test were entered in a multivariate analysis to determine the independent significance of different factors. Also, children 1 to 9 years of age tend to have a better … Management of Refractory Pediatric Sarcoma: Current Challenges and Future Prospects. estimated a 5‐year survival rate after recurrence of approximately 50% for patients who were diagnosed initially with 1) botryoid tumors, 2) Stage I or Group I tumors (nonalveolar or alveolar) with local or regional recurrence, and 3) Group I alveolar or undifferentiated RMS.6 Our results differed to some degree, because the IRS clinical group does not emerge as a risk factor even in univariate analysis, probably because our sample was less numerous and included fewer botryoid RMS, and the analysis was limited to localized RMS. 2 Greater than 90% of children with nonmetastatic RMS now achieve complete tumor remission with current multidisciplinary treatment, which includes chemotherapy, radiotherapy (XRT), and surgery. It … Late effects of therapy in orbital rhabdomyosarcoma … The Ignatius laboratory is interested in understanding the effects of tumor heterogeneity on relapse and resistance to therapies in Rhabdomyosarcoma and other sarcomas. Manzella G, Schreck LD, Breunis WB, Molenaar J, Merks H, Barr FG, Sun W, Römmele M, Zhang L, Tchinda J, Ngo QA, Bode P, Delattre O, Surdez D, Rekhi B, Niggli FK, Schäfer BW, Wachtel M. Nat Commun. Survival outcomes of patients with localized FOXO1 fusion‐positive rhabdomyosarcoma treated on recent clinical trials: A report from the Soft Tissue Sarcoma Committee of the Children's Oncology Group. It is now possible to cure nearly 3 of every 4 children with rhabdomyosarcoma. For patients with embryonal tumors, the estimated 5-year survival rate was 52% for patients who initially presented with stage 1 or group I disease, 20% for those with stage 2/3 or group II/III disease, and 12% for those with group IV disease. Introduction. Background: Simultaneous targeting of insulin-like growth factor-1 receptor and anaplastic lymphoma kinase in embryonal and alveolar rhabdomyosarcoma: A rational choice. We report a case of an 18-year-old male whose disease relapsed in the abdominal cavity after a testicular ERMS curative resection. Patients with a single risk factor (32%) had an OS rate of 37.5% ± 17.2%. Methods A 20 year old male presented with a 3 week history of headaches and nausea. Rhabdomyosarcoma is known as the malignancy of striated muscles. Results of the second study of the International Society of Paediatric Oncology: MMT84, Value of postchemotherapy bioptical verification of complete clinical remission in previously incompletely resected malignant mesenchymal tumors in children: SIOP 84 malignant mesenchymal tumours study, Treatment of children with relapsed soft tissue sarcoma: report of the German CESS/CWS REZ 91 trial, Prognosis of children with soft tissue sarcoma who relapse after achieving a complete response. Results: Embryonal rhabdomyosarcoma (ERMS) ERMS usually affects children in their first 5 years of life, but it can occur at older ages as well. The median time from diagnosis to recurrence was 17.8 months. 2020 Jun;74(3):240-242. doi: 10.5455/medarh.2020.74.240-242. Among the variables at recurrence, the type and time of recurrence and its relation with therapy were associated strongly with survival (see Table 2). Clinical outcomes from a multi-institutional cohort. None of the children with 3 or 4 risk factors were alive after 5 years (P < 0.0001). Rhabdomyosarcoma and undifferentiated sarcoma in the first two decades of life: a selective review of intergroup rhabdomyosarcoma study group experience and rationale for Intergroup Rhabdomyosarcoma Study V. Prognostic factors and surgical treatment guidelines for children with rhabdomyosarcoma of the perineum or anus: a report of Intergroup Rhabdomyosarcoma Studies I through IV, 1972 through 1997. Histology also proved significant, with nonalveolar RMS associated with a longer survival (P = 0.05). Patients and Methods The analysis included children with nonmetastatic RMS and embryonal sarcoma enrolled onto the International Society of Paediatric Oncology (SIOP) Malignant … found that patients who received salvage regimens that included XRT had a significantly better survival (3‐year event‐free survival rate, 46% vs. 10%; P = 0.002).12 This is confirmed by our own experience: Patients who had no or only one risk factor and patients who had RMS with nonalveolar histology and had not received XRT during their initial treatment had better outcomes after recurrence: This presumably was due to the XRT given during second‐line treatment. The administration of XRT during first‐line therapy and the initial protocol also were considered in the analysis. In fact, patients who had no or only one risk factor and patients who had tumors with a nonalveolar histology benefited more from salvage therapy if they had not received radiotherapy for their initial treatment. Whereas the best timing and modulation of local tumor control still is debated, the development of methods for ascertaining the presence of minimal residual disease is desirable. Rhabdomyosarcoma is an aggressive neoplasm with a propensity for early local infiltration and eventual metastatic dissemination. Local therapy is difficult to manage in patients with RMS because of the site of the primary tumor and the possible late effects of XRT, because the majority of children with RMS are very young. 2004 May 15;22(10):1902-8. doi: 10.1200/JCO.2004.08.124. Patient variables included age at diagnosis and recurrence and gender. Primary tumor site, histologic subtype (alveolar or nonalveolar), regional lymph node involvement, and tumor size at the time of initial diagnosis also were considered. Multivariate analysis identified 4 factors that were associated with poor survival: 1) alveolar subtype (relative risk [RR], 2.0), 2) parameningeal or “other” sites (RR, 2.6), 3) systemic recurrence (RR, 3.1), and 4) recurrence on therapy (RR, 2.3). 2020 Aug 6;10:1228. doi: 10.3389/fonc.2020.01228. Does the time‐point of relapse influence outcome in pediatric rhabdomyosarcomas?. E‐RMS, embryonal rhabdomyosarcoma; A‐RMS, alveolar rhabdomyosarcoma; P‐RMS, “adult‐type” rhabdomyosarcoma. XRT was not recommended in children age < 3 years, and primary reexcision was the treatment of choice, wherever feasible. Although > 90% of children with nonmetastatic rhabdomyosarcoma (RMS) achieve complete remission with current treatment, up to one‐third of them experience a recurrence. ... Relapses are less common after 5 years but around 9% may relapse after 10 years. Embryonal rhabdomyosarcoma (ERMS) is a rare histological form of cancer of connective tissue wherein the mesenchymally-derived malignant cells resemble the primitive developing skeletal muscle of the embryo. Initial Patient Characteristics Can Predict Pattern and Risk of Relapse in Localized Rhabdomyosarcoma. Embryonal rhabdomyosarcoma (ERMS), a rare category of soft tissue sarcoma (STS), originates in the mesenchymal tissue. The results of multivariate analysis were used to develop a risk‐stratification model, and survival was calculated on the basis of the number of prognostic factors for each child (Fig. Among patients with alveolar or undifferentiated sarcoma, only the disease group predicted outcome: the 5-year survival estimate was 40% for group I versus 3% for groups II through IV. In fact, the patients who had most favorable prognosis were those with GU non‐B/P RMS (OS, 60.0%; 95% confidence interval [95%CI], 17.1–100.0%) or orbit RMS (OS, 55.9%; 95%CI, 33.0–78.8%). But for kids whose tumors grow back, or when the cancer spreads to other areas of the body, we face a major challenge… The impact of radiotherapy on clinical outcomes in parameningeal rhabdomyosarcoma. Relapse is a significant problem in the clinic where less than 40% of patients with relapse … After the third relapse, she was treated with prednisolone and cyclosporine (at initial dose of 50mg/day [1.7mg/kg/day]) for immunosuppression. Management of Refractory Pediatric Sarcoma: Current Challenges and Future Prospects. Univariate analysis showed that tumor histology was an important predictor of 5-year survival (P <.001): the 5-year survival rate was 64% for patients with botryoid tumors (n = 19), 26% for patients with embryonal tumors (n = 313), and 5% for patients with alveolar or undifferentiated sarcoma (n = 273). A report from the AIEOP Soft Tissue Sarcoma Committee. 31 It is the most common sarcoma of childhood, accounting for 5% to 15% of all childhood solid tumors and 4% to 8% of all childhood malignancies. Time to recurrence was classified further according to whether the recurrence occurred before (on therapy) or after (off therapy) treatment was completed. The purpose of surgical exploration after chemotherapy alone is to avoid XRT or use it in lower doses. 2). Failure pattern and factors predictive of local failure in rhabdomyosarcoma: a report of group III patients on the third Intergroup Rhabdomyosarcoma Study. Only about 15-20% of patients will have visible spreading (metastasis) of … Relapse … With early diagnosis and treatment, 80% of children with embroyonal rhabdomyosarcoma will survive with today’s treatment options. Raney RB, Anderson JR, Barr FG, Donaldson SS, Pappo AS, Qualman SJ, Wiener ES, Maurer HM, Crist WM.

This mathematical model does not take single risk factors into account. We report a case of an 18-year-old male whose disease relapsed in the abdominal … The clinical characteristics of this population, the treatment modalities, and the types of recurrence were analyzed and correlated with the patients' survival. 2020 Jun 8;13:5093-5112. doi: 10.2147/OTT.S193363. The data emerging from this study may be useful in planning risk‐adapted salvage protocols, such as the Children's Oncology Group ARST 0121 randomized Phase II window study concerning new drug combinations. Does surgery have a role in the treatment of local relapses of non‐metastatic rhabdomyosarcoma?. Tumor histology (embryonal rhabdomyosarcoma is more favorable than alveolar). Histologic and Clinical Characteristics Can Guide Staging Evaluations for Children and Adolescents With Rhabdomyosarcoma: A Report From the Children's Oncology Group Soft Tissue Sarcoma Committee. Please check your email for instructions on resetting your password. Radiation therapy is an important factor to improve survival in pediatric patients with head and neck rhabdomyosarcoma by enhancing local control: a historical cohort study from a single center. Outcome data from five trials and one registry of the Cooperative Weichteilsarkom Studiengruppe (CWS). If you do not receive an email within 10 minutes, your email address may not be registered, Outcome of children with neuroblastoma after progression or relapse. Late Relapse of Botryoid Embryonal Rhabdomyosarcoma of the Vagina in Prepubertal Age. Patients with GU non‐B/P RMS and orbit RMS had the best outcomes (60% and 56%, respectively), whereas patients with “other” and PM sites had the worst outcomes (18.8% and 0%, respectively). Under the microscope, rhabdomyosarcoma can look similar to several other types of children’s cancers such as neuroblastoma, Ewing sarcoma and lymphoma. The authors thank Ilaria Zanetti and Angela Scagnellato for data processing and Gloria Tridello and Gianluca De Salvo for the statistical analysis.

About 4 years after the diagnosis of nephrotic syndrome had been made, an embryonal rhabdomyosarcoma … Further analysis identified prognostic factors within histologic subtypes (P <.001). Because skeletal muscle cells are found in virtually every site of the body, RMS can develop in almost any part of the body. Embryonal rhabdomyosarcoma (ERMS) has a low prevalence, poor prognosis, and limited treatment efficacy. A better understanding is needed of which patients can be salvaged after first relapse. 2003 Mar;38(3):347-53. doi: 10.1053/jpsu.2003.50106. In many other cases, combination with radiation therapy may be used to minimize the risk of tumor recurrence or relapse. We present the case of a late relapse of RMS to the leptomeninges after 15 years. Spindle cell RMS is a rare variant of embryonal RMS that has a predilection for young … Among the 41 patients who had disease progression, 39 patients died of disease, and 2 patients achieved a long‐term remission and were alive 4 years and 10 years after progression. Of the 445 patients with nonmetastatic RMS who were enrolled in AIEOP protocols, 41 patients (9.2%) experienced disease progression; these children were excluded from our analysis, because the definition of recurrence implies the prior achievement of complete remission. High incidence of regional and in-transit lymph node metastasis in patients with alveolar rhabdomyosarcoma. Combining patients with 0 or 1 risk factor, the OS rate was 66.5% in the subgroup who had not received radiotherapy compared with an OS rate of 30.3% in the subgroup who had received radiotherapy; this difference was significant (P = 0.03). SYNOVIAL SARCOMA OF THE NECK IN A CHILD: A Multidisciplinary Approach. The first‐line treatment was assigned on the basis of the initial surgery. Local Failure in Parameningeal Rhabdomyosarcoma Correlates With Poor Response to Induction Chemotherapy. Phenotypic profiling with a living biobank of primary rhabdomyosarcoma unravels disease heterogeneity and AKT sensitivity. 2001 May;23(4):215-20. doi: 10.1097/00043426-200105000-00008. J Pediatr Surg. HR: hazard ratio; 95%CL: 95% confidence limits; GU: genitourinary; PM: parameningeal; HN: head and neck; B/P: bladder/prostate. We used the prognostic factors identified by multivariate analysis to develop a risk‐stratification model for children with recurrent RMS. These findings will form the basis of a multi-institutional risk-adapted relapse protocol for childhood rhabdomyosarcoma. Mesenchymal, Fibroosseous, and Cartilaginous Orbital Tumors. Rhabdomyosarcoma is the most common type of soft tissue and bone sarcoma, a type of childhood cancer. Not very much is known about why normal skeletal muscle cells become cancerous. Learn more. Patterns of Failure in Pediatric Rhabdomyosarcoma After Proton Therapy. It is the most common soft tissue sarcoma occurring in children. RMS is historically classified based on histopathologic features into distinct clinical subtypes— embryonal RMS (ERMS), alveol… Cancer 1982;49:2217-21. The median survival time from first recurrence was 0.8 years; the estimated percentage of patients who survived 5 years from first recurrence was 17% +/- 2% (mean +/- SD). Embryonal Rhabdomyosarcoma research; Stem Cell Biology; Research. The relation of each factor (i.e., alveolar histology) to prognosis in the absence of other factors and with respect to XRT could not be assessed because of the small number of patients in each subgroup. Primary tumor site (P < 0.0001), tumor size (P = 0.0008), histology (P = 0.05), and prior XRT (P = 0.0051) were associated significantly with survival after recurrence. During follow-up, 3 patients experienced local relapse and 5 distant relapse. Unfortunately, only 12% of patients who develop recurrent disease belong to the group with a highly favorable prognosis. RMS cells resemble skeletal muscle progenitor cells, though they can arise from non-skeletal tissue origins (3). Journal of Pediatric Hematology/Oncology. In the current retrospective study, we identified several factors that are important in determining the likelihood of survival for patients with recurrent RMS. A specific analysis for botryoid tumors was impossible in our study because of the small number of patients with this histologic subtype (n = 6 patients). This site needs JavaScript to work properly. Journal of Clinical Oncology 1999; 17:3487-3493. We present the case of a late relapse of RMS to the leptomeninges after 15 years. The first step in planning second‐line treatment is to identify prognostic factors in these patients, so that risk‐adapted protocols can be developed. When disease recurrence occurs, further treatment should be planned in the light of the first‐line therapy and the risk factors identified. Among 24 patients with 3 or 4 risk factors (dashed and dotted line), there were 21 treatment failures (5‐year OS not applicable). Albert & Jakobiec's Principles & Practice of Ophthalmology. Pharmacological inhibition of EZH2 as a promising differentiation therapy in embryonal RMS. Wharam MD, Meza J, Anderson J, Breneman JC, Donaldson SS, Fitzgerald TJ, Michalski J, Teot LA, Wiener ES, Meyer WH. No significant differences emerged when patients were analyzed by protocol (see Table 2). Patients with a nonalveolar histology, primary tumor site different from parameningeal and “other” sites, local recurrence, and recurrence off therapy had a better prognosis. Purpose Previous studies suggest poor outcome in children with relapsed rhabdomyosarcoma (RMS). Case Report of a Local Recurrence of Spindle Cell Embryonal Rhabdomyosarcoma. Children with RMS who have systemic recurrences are more difficult to rescue, and only 10% survive at 5 years. Gaslini” Children's Hospital, Genoa, Italy, Division of Pediatric Surgery, Department of Pediatrics, University‐Hospital of Padua, Padua, Italy, Pediatric Oncology Unit, Istituto Tumori of Milan, Milan, Italy, Radiotherapy Division, Hospital of Padua, Padua, Italy, Division of Pediatric Oncology, “Bambino Gesû” Pediatric Hospital IRCSS, Rome, Italy, Pediatric Oncology Unit, “Regina Margherita” Children's Hospital, University of Turin, Turin, Italy, Pediatric Oncology Unit, Hospital of Cagliari, Cagliari, Italy. Working off-campus? Multivariate analysis found that two characteristics of the initial tumor (histology and primary site) and two characteristics of the recurrence (type and temporal relation with therapy) were associated significantly with prognosis. Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children, and can be subcategorized histologically and/or based on PAX-FOXO1 fusion gene status. Aim Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumour of childhood. 2020 Jun 23;18:202-214. doi: 10.1016/j.omto.2020.06.018. The use of experimental therapies may be questionable for children with a single risk factor (32%), whose prognosis is not so poor. USA.gov. NIH About 4 years after the diagnosis of nephrotic syndrome had been made, an embryonal rhabdomyosarcoma … The embryonal subtype was the most common, as expected. There are 2 main types of rhabdomyosarcoma that is found in children: embryonal, alveolar and anaplastic rhabdomyosarcoma. After the third relapse, she was treated with prednisolone and cyclosporine (at initial dose of 50 mg/day [1.7 mg/kg/day]) for immunosuppression. In the United States, about 350 new cases are diagnosed each year in children under 15. There are two kinds of muscle cells in the body: smooth muscle cells and skeletal muscle cells. Prognostic factors after relapse in nonmetastatic rhabdomyosarcoma: a nomogram to better define patients who can be salvaged with further therapy. Most patients had local recurrences (72%). 1), with a median survival of 15.4 months. Facial rhabdomyosarcoma with an isolated pancreatic metastasis. 1 Multimodality therapy with surgery, radiation therapy, and cytotoxic chemotherapy has resulted in approximately 70% of patients achieving long‐term survival. Late relapse of embryonal rhabdomyosarcoma, botryoid variant, of the vagina @article{Vasquez2008LateRO, title={Late relapse of embryonal rhabdomyosarcoma, botryoid variant, of the vagina}, author={R. Vasquez and P. Collini and C. Meazza and F. Favini and M. Casanova and A. Ferrari}, journal={Pediatric Blood & Cancer}, year={2008}, … Klingebiel et al.12 confirmed that patients with recurrent embryonal tumors fared significantly better. Patients with alveolar RMS survived longer if they had not received XRT: The survival rate was 20.8% (95%CI, 0.0–43.1%) versus 6.2% (95%CI, 0.0–17.2%) in the subgroup of patients who received XRT, but the difference was not statistically significant (P = 0.40). Among 46 patients with 2 risk factors (short dashed line), there were 34 treatment failures (5‐year OS, 16.1%; 95%CI, 3.4–28.8%). Aberrant CDK4 Amplification in Refractory Rhabdomyosarcoma as Identified by Genomic Profiling. 2020 Sep 15;11(1):4629. doi: 10.1038/s41467-020-18388-7. Most of them were classified in IRS Group III (72.8%). For patients with stage 1/group I disease, estimated 5-year survival rates were higher for patients with local (72%) or regional (50%) recurrence than for those with distant (30%) recurrence. This is the overall survival curve for all patients with nonmetastatic rhabdomyosarcoma who developed recurrent disease after achieving a complete remission. The 5‐year overall survival (OS) rate was 28.3% ± 8.7%. In salvage protocols, patients with no risk factors may benefit from intensive standard chemotherapy and XRT, whereas experimental treatments should be reserved for patients with more than one unfavorable risk factor. Univariate analysis showed a higher 5‐year OS rate for Group III patients compared with Group II patients, but the difference was not statistically significant. Despite advances in therapy, nearly 30% of children with rhabdomyosarcoma experience progressive or relapsed disease, which is often fatal. J Clin Oncol. [ 5, 6, 25] Relapses are uncommon in patients who were alive and event free at 5 years, with a 10-year late-event rate of 9… The 5‐year OS rates per prognostic variable are given in Table 2. Death due to any cause was considered an event. This is consistent with the experience of Pappo et al.6 who, considering children with Group I–IV disease who were treated on the IRS‐III, IRS‐IV pilot, and IRS‐IV protocols, reported a 5‐year survival rate after recurrence of 5% for patients with an alveolar histology compared with 26% for patients with the embryonal subtype. The OS rates for patients with RMS arising in non‐PM HN, extremity, and GU B/P sites were 48.8%, 42.1%, and 32.4%, respectively. Defining the impact of prognostic factors at the time of relapse for nonmetastatic rhabdomyosarcoma. Follow‐up was updated at September, 2003. A possible explanation may be the higher percentage of alveolar tumors in Group II than in Group III (47% vs. 34%), whereas no difference was documented in the use of XRT as first‐line therapy in these patient subsets (63% and 60% in Groups II and III, respectively). These tend to remain localized and are often embryonal… Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children, comprising 4.5% of all childhood cancer with an annual incidence of 4.5 cases per 1 million children (1, 2). Up to one‐third of patients experience recurrence, 3-5 however. Outcome of pediatric parameningeal rhabdomyosarcoma. Cancer 2005;. Front Oncol. Survival. Rhabdomyosarcoma (RMS or ‘rhabdo’) is a tumor made up of cancerous cells that look like immature muscle cells. Blakely ML, Andrassy RJ, Raney RB, Anderson JR, Wiener ES, Rodeberg DA, Paidas CN, Lobe TE, Crist WM; Intergroup Rhabdomyosarcoma Studies I through IV. The recurrence was local in 90 patients (72%) and systemic in 35 patients (28%). Introduction. The primary tumor site was orbit in 15.2% of patients, nonparameningeal head and neck (non‐PM HN) in 12.8% of patients, parameningeal (PM) in 14.4% of patients, extremity in 15.2% of patients, genitourinary bladder/prostate (GU B/P) in 6.4% of patients, genitourinary nonbladder/prostate (GU non‐B/P) in 4.8% of patients, and “other” sites in 31.2% of patients (trunk, paraspinal region, intrathoracic and intraabdominal organs, pelvis, and perineal region). Patient, tumor, and treatment characteristics were studied in univariate and multivariate analyses to determine the independent significance of different factors.
