Introduction

Bone and soft tissue sarcomas are relatively rare cancers that collectively account for approximately 1% of adult solid tumors and 12% of all pediatric malignancies (Burningham et al. 2012; Ries et  al. 1999). Major bone tumors include osteosarcoma and Ewing sarcoma, whereas soft tissue sarcomas are largely categorized by rhabdomyosarcoma and non-rhabdomyosarcoma soft tissue sarcomas. In spite of their relative infrequency, these tumors remain a leading cause of cancer death in individuals 10  years of age significantly improved their outcome, whereas it had no effect on boys under 10. Therefore, on COG studies ipsilateral lymph node dissection is required for boys over 10 with paratestis primaries, and for boys under 10 with imaging findings concerning for nodal involvement. The European MMT group has taken a different approach, preferring more intensive therapy for paratestis pri-

mary tumors over node sampling (Stewart et  al. 2003). The Italian and German study compared the clinical and surgical/pathologic stages in 95 children with paratesticular rhabdomyosarcoma: among 72 patients with negative radiologic findings (cN0), surgical/pathological assessment detected nodal involvement in only one case (pN1). This finding suggested that CT accurately evaluates the retroperitoneum. In analyses of only those patients older than 10 years, results did not seem different, even if the number of cases was substantially lower (13 of 13 cN0 patients were pN0 too) (Ferrari et al. 2002). On the basis of these results, the EpSSG protocol considered retroperitoneal lymphadenectomy or nodal sampling at diagnosis as not recommended unless there is uncertainty on imaging. The planned COG intermediate risk study will require pathologic evaluation of nodes in all patients with extremity tumors and strongly

encourages it for patients with ARMS or clinically involved nodes regardless of histology. The preferred method of nodal evaluation is sentinel node sampling since this has been shown to be useful and feasible in pediatric patients with soft tissue sarcomas, even in a case reported with parameningeal RMS (De Corti et al. 2009; Weiss et al. 2011). FDG-PET is being used more commonly in initial staging evaluation of sarcomas and is also being evaluated for response assessment. A small study of 13 children and adolescents with histologically proven RMS found FDG-PET scanning to be more sensitive than conventional imaging in detection of lymph nodes and bone metastases; however subcentimeter pulmonary nodules may not consistently be detected (Ricard et al. 2011). Moreover in one patient FDG-PET scan was positive in lymph nodes due to concurrent infection. In this series, FDG PET modified lymph node staging in four of 13 patients, bone involvement in two patients, and led to treatment alteration in two patients. A prospective study of 46 pediatric sarcoma patients, of whom 12 had RMS, found similar results in the superiority of FDG-PET scan in detection of lymph node and bone metastases, but not subcentimeter lung nodules (Volker et al. 2007). A limitation of both studies was that positive imaging was not consistently confirmed pathologically. Klem and colleagues also evaluated FDG-PET for initial staging in 24 patients with RMS and determined it to be 77% sensitive and 95% specific when compared with the final clinical determination of disease but still concluded that although “PET is a helpful adjunct… is not accurate enough to replace biopsy of suspicious nodes” (Klem et  al. 2007). Federico and colleagues had similar conclusions in terms of high sensitivity for detection of nodal disease but low sensitivity in detection of lung disease (Federico et al. 2013). Mody et al. retrospectively evaluated 25 children with Ewing sarcoma family of tumors and rhabdomyosarcoma who had PET scans at various time points during therapy and found sensitivity of the PET scan was 86%, specificity was 80%, positive predictive value was 89%, and negative predictive value was 67%

(Mody et al. 2010). Wegner and colleagues found PET scans to result in a change in management or be helpful in determining management of a wide variety of pediatric malignancies (Wegner et  al. 2005). Gerth and colleagues found combining PET and CT to be significantly more accurate than PET alone in  localization and detection of lesions in patients with Ewings sarcoma, and most PET imaging is now fused with CT imaging (Gerth et  al. 2007). Eugene et  al. evaluated 23 patients with RMS with PET/CT and conventional imaging and confirmed again that PET/CT provides important additional staging information as well as being prognostic for tumor response, but effect of PET response on outcome was not evaluated (Eugene et  al. 2012). On the planned next intermediate risk Children’s Oncology Group RMS study, data will be collected on results of FDG-PET scan and nodal biopsy to determine rates of false positivity and negativity for FDG-PET scans. Surprisingly, tumor response by conventional anatomic imaging in patients with RMS does not correlate with outcome in two COG studies (Burke et al. 2007; Rosenberg et al. 2014). This is in contrast to the findings of two European groups, the Italian and German CWS group which found a correlation between the degree of shrinkage after induction chemotherapy (assessed radiologically after three courses of therapy) and final outcome, leading to subsequent European trials using radiologic response to tailor subsequent treatment (Koscielniak et al. 1999; Ferrari et al. 2010). Two recent studies from Memorial Sloan Kettering Cancer Center suggest that functional imaging with FDG-PET scan after local control with radiation as well as after up front chemo were predictive of EFS, overall survival, as well as local control (Casey et  al. 2014; Dharmarajan et al. 2012). A small study of adults with high-grade sarcomas by Tateishi et al. suggested that metabolic reduction after neoadjuvant chemotherapy evaluated by FDG PET can be used for stratification of histopathologic response in patients with high-grade sarcoma and that percentage of SUV2 reduction as well as histopatho-

logic response were independent predictors of outcome (Tateishi et  al. 2011). Correlation of PET response with outcome and histopathologic response in soft tissue sarcomas will require further evaluation and confirmation. A number of investigators have investigated correlation of PET response with outcome and histopathologic response in Ewing sarcoma and osteosarcoma. Hawkins et  al. evaluated 36 patients with Ewing sarcoma family of tumors and reported that not only did PET imaging corerlate with histologic response, but SUV2 less than 2.5 was predictive of progression-free survival (PFS) independent of initial stage (Hawkins et  al. 2005). The same investigators found that PET response was only partially correlated with histopathologic response to chemotherapy in osteosarcoma, although an SUV2
