Abstract
PURPOSE The results achieved in 44 patients with nonmetastatic peripheral neuroectodermal tumor (PNET) of bone treated with neoadjuvant chemotherapy are reported. PATIENTS AND METHODS A six-drug regimen of chemotherapy (vincristine, doxorubicin, dactinomycin, cyclophosphamide, ifosfamide, and etoposide) was administered to all patients. Local treatment consisted of surgery in 20 patients, surgery followed by radiotherapy in 13, and radiotherapy only in 11. RESULTS At a mean follow-up of 4.5 years (range, 2 to 7 years), 23 patients (52%) remain event-free, 20 have relapsed (45%), and one has died of chemotherapy-related toxicity. The 5-year event-free survival and overall survival were 54.2% and 62.7%, respectively. To assess the prognostic significance of neural differentiation in the family of Ewing's sarcoma, these results have been compared with the outcomes of 138 concomitant patients with typical Ewing's sarcoma (TES) who were treated according to the same protocol. Of these, 103 (75%) remained continuously event-free, 34 (24%) relapsed, and one died of chemotherapy-related toxicity. It follows that PNET patients treated with this chemotherapy regimen have a significantly worse prognosis than typical ES patients (5-year event-free survival, 54.2% v 70.6%, P <.012; 5-year overall survival, 62.7% v 78.3%, P <.002). CONCLUSION The authors conclude that studies into new adjuvant therapy for Ewing's sarcoma modulated according to risk of relapse should also consider neural differentiation as a risk factor.

Abstract
Among Ewing's sarcoma (ES) of bone and related entities are tumours with neuro-ectodermal features that could represent a biologically distinct type. In order to assess the prognostic significance of the various forms of ES, a retrospective joint study involving three cancer centres in Europe and the U.S.A. was initiated. The material from 315 primary ES was reviewed by a panel of five pathologists and classified as typical ES (220 cases), atypical ES (48 cases) or ES with neuro-ectodermal features (47 cases). Prognostic factor analysis on treatment failure-free survival was performed using the Cox model. It included histopathological classification, initial patient characteristics, clinical presentation and treatment type. After multivariate analysis, in addition to treatment type (P < 0.001), metastases (P = 0.003) and proximal tumour location (P = 0.006), two histopathological parameters correlated with poor treatment failure-free survival, the presence of filigree pattern (P = 0.044) and dark cells (P = 0.043). We conclude that ES with neuro-ectodermal features does not appear to have a different outcome to the other subtypes.

Abstract
Seventy-nine cases of small round cell tumors involving bone were studied in an attempt to learn whether the immunohistochemical features of the lesions might allow distinction of small cell osteosarcoma from other potential differential diagnostic considerations, including Ewing's sarcoma, atypical Ewing's sarcoma, primitive neuroectodermal tumor, mesenchymal chondrosarcoma, lymphoma, and the Askin tumor. The tissues studied were all formalin-fixed, decalcified, paraffin sections from patients between the ages of 16 and 48 years. With one exception (a small cell osteosarcoma), none of the lesions was cytokeratin positive. Moreover, none of the lesions was epithelial membrane antigen, desmin, factor VIII-related antigen, synaptophysin, or Leu-M1 positive. Accordingly, strong positivity for these antibodies in a majority of tumor cells should prompt inclusion of tumor types other than those listed above in the differential diagnosis. Vimentin positivity was seen in a majority of the tumors studied irrespective of histologic type. Scattered tumor cells (< 25%) showed positivity with antibodies to muscle-specific actin and smooth muscle actin in several of the different tumor types studied. No lesions other than lymphoma were leukocyte-common antigen (LCA) positive; all but two lymphomas were LCA positive, while all but one lymphoma were L26 positive. One (lymphoblastic) lymphoma was LCA and L26 negative. S-100, neuron-specific enolase, and Leu-7 did not prove to be specific for "neural-associated" tumors, but rather appeared in some small cell osteosarcomas, Ewing's sarcomas, atypical Ewing's sarcomas, primitive neuroectodermal tumors, mesenchymal chondrosarcomas, lymphomas, and Askin tumors. Antibody to cell surface antigen HBA71 was positive in three Ewing's sarcomas (two typical and one atypical) and negative in small cell osteosarcoma (three cases), mesenchymal chondrosarcoma (two cases), and lymphoma (one case). While some guidance may be derived from analysis of immunohistochemical staining patterns in a given lesion, the results reported in the present study do not suggest that routine immunohistochemistry alone will permit distinction of these small cell tumors of bone from one another. The value of immunohistochemical studies appears to lie particularly in the use of antibodies to LCA and S-100 protein to distinguish lymphoma and mesenchymal chondrosarcoma, and perhaps antibody to HBA71 to distinguish neural family lesions (such as Ewing's sarcoma), from other small cell tumors, such as small cell osteosarcoma.

Abstract
Recent reports of Ewing's sarcoma (EW) and extraskeletal Ewing's sarcoma (EEW) support the hypothesis that these tumors are neuroectodermal in origin. Primitive neuroectodermal tumors (PNET) of bone (32 cases) and soft tissue (25 cases) including those previously categorized as EW in 27 cases and EEW in 15 cases were carefully studied histologically, immunocytochemically and morphometrically, focusing on tumor cell differentiation. This study attempts to subclassify these tumors on the basis of the size of tumor cells and nuclei, their variations (uniformity or diversity), arrangement of tumor cells (rosette or non-rosette), focal differentiation to larger ganglion-like cells, and staining intensity for neural markers. All tumors were histologically subclassified as small, medium or large cell types, three basic subtypes (rosette type, abortive rosette type, non-rosette type) and four complementary subtypes (fibrillary type, non-fibrillary type, angiomatoid type, ganglion cell type). Classic EW or EEW is consistent with small or medium, non-rosette, non-fibrillary type tumors, previously described large cell EW with large, non-rosette, fibrillary or non-fibrillary type tumors, and classic neuroectodermal tumor with small or medium, rosette, fibrillary type tumors, according to the present subclassification. Clinicopathologic correlations with the different subtypes are discussed. Long-term survival, more than 5 years, was seen in patients with small cell type, and those younger than 14 years of age.

Abstract
The pathologic material from 56 patients diagnosed initially as Ewing's sarcoma of the distal extremity and treated on National Cancer Institute protocols between 1968 and 1984 was reviewed and correlated with clinical outcome. Histologically, the tumors were categorized, based on recent pathologic criteria, into three diagnostic groups: (1) typical Ewing's sarcoma, (2) atypical Ewing's sarcoma, and (3) other (predominantly peripheral neuroepithelioma [PN]). Thirty-two patients (57%) had typical Ewing's, 13 (23%) were atypical, and 11 (20%) were in the "other" diagnostic category (seven [13%] PN, two primitive rhabdomyosarcoma, one primitive sarcoma of bone, and one synovial cell sarcoma). No cases of metastatic neuroblastoma, osteosarcoma, or lymphoma were found. Forty-five patients had localized disease at diagnosis; 11 had metastases. Patients with typical Ewing's sarcoma were less likely to have metastatic disease at the time of diagnosis. Only two of 32 patients with typical Ewing's sarcoma had metastases compared with nine of 24 patients in the two other groups. The pattern of relapse was also different in these other groups compared with typical Ewing's patients; five patients developed lymph node metastases and two patients developed brain metastases. Although the presence of metastatic disease at diagnosis was a strong negative prognostic factor, our histologic grouping was independently prognostic of clinical outcome in patients with localized disease. Patients with typical osseous Ewing's sarcoma had an improved overall survival (P2 = 0.03) and patients with other tumors (neither typical nor atypical Ewing's sarcoma) had a poorer disease-free survival (P2 = 0.02). Since no generally accepted histopathologic prognostic criteria exist for Ewing's sarcoma, the potential value of our proposed classification should be evaluated in a larger retrospective and a prospective study.

Abstract
Clinical, cytogenetic, histopathologic, and immunohistochemical data were obtained in a series of 11 small round cell tumors (SRCT) of bone and soft tissue with the translocation t(11;22) (q24;q12). Ten cases were primary in bone, and one was of extraskeletal origin. According to conventional histopathologic criteria, 10 cases were Ewing's sarcomas (ES) and one was a peripheral neuroectodermal tumor (PNET). Besides the t(11;22), six cases had additional chromosomal aberrations, including trisomy 7 and partial trisomy for the long arm of chromosome 1, which have both been described as nonspecific secondary abnormalities often associated with tumor progression. The tumors were screened for neural differentiation with an antibody panel consisting of neuron-specific enolase, S100 protein, Leu-7, chromogranin, synaptophysin, and neurofilament. Three cases of ES were positive for S100 protein. The PNET and one case of ES were positive for neuron-specific enolase. All of the remaining immunohistochemical stains were negative. Hence, five of 11 SRCT of bone or soft tissue with the t(11;22) showed morphologic and/or immunohistochemical evidence of neural differentiation. In this limited series of cases, no cytogenetic or prognostic differences could be demonstrated between cases with and without a neural phenotype. Our results support the hypothesis that SRCT of bone of soft tissue with the t(11;22) form a single biologic entity displaying varying degrees of neuroectodermal differentiation. The clinical significance of additional cytogenetic abnormalities and of morphologic or immunohistochemical evidence of neural differentiation in this group of tumors needs to be further studied.
