本文通过对11例经病理证实的软组织肉瘤患儿进行临床分析。指出手术广泛切除仍是决定预后最重要因素。肿瘤大小、部位及组织学分期与局部复发关系不大,但>10cm及高分期肉瘤病人预后不良。对于高分期病人使用放疗可提高存活率,对于低分期的可以预防局部复发。本文还就临床分期、病理分级及治疗方案选择与预后的关系进行探讨。 相似文献

横纹肌肉瘤(Rhabdomyosarcoma,RMS)是儿童期最常见的软组织肉瘤。RMS的光镜诊断基于识别横纹肌母细胞,但其表现可呈从原始间充质细胞到胚胎型肌小管的不同分化状态,低分化类型非常多见,约占20%~60%,不仅难以与其它小圆细胞瘤相鉴别,而且也难以进行分类及估计预后。 相似文献

横纹肌肉瘤(RMS)有早期就诊率低、恶性程度高、进展快及手术难以完全切除且易致术后畸形等特点。影像学检查、局部细针穿刺病理诊断是早期诊断RMS的主要方法。化疗、外放疗、放射性粒子植入术、自体外周血造血干细胞移植及手术治疗是目前治疗RMS的主要方法。[临床儿科杂志,2012,30(5):404-407] 相似文献

OBJECTIVE: To determine the value of postoperative radiotherapy (RT) in the management of nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) of childhood. PROCEDURE: From 1964 to 2000, 62 children with a median age of 14 years were seen at the University of Iowa and underwent a wide local excision for non-metastatic NRSTS. Tumors were high grade in 36 (58%) and >5 cm in 24 (39%). Margins of resection were negative (Group I) in 37 (60%) and positive (Group II) in 25 (40%). Postoperative RT was delivered to 20 patients (32%); eight of 37 (22%) Group I and 12 of 25 (48%) Group II children received postoperative RT. Chemotherapy was employed in 19 patients (31%). Median follow-up was 9.6 years. RESULTS: The 5- and 10-year overall survival rates for Group I were 69 and 63% and for Group II were 66 and 60%. The 5- and 10-year local control rate was 66%. On multivariate analysis, size of tumor (P < 0.001) and postoperative RT (P = 0.017) were prognostic factors for local control. All 13 Group I children with low grade, =5 cm tumors were locally controlled without RT. For Group II patients, 2- and 5-year local control rates were 92 and 82% with postoperative RT and 51 and 43% for no RT (P = 0.0426). CONCLUSIONS: Local control was improved by the addition of postoperative RT in tumors with positive margins of resection. 相似文献

Pediatric soft tissue sarcomas are a group of malignant neoplasms arising within embryonic mesenchymal tissues during the process of differentiation into muscle, fascia and fat. The tumors have a biphasic peak for age of incidence. Rhabdomyosarcoma(RMS) is diagnosed more frequently in younger children, whereas adult-type non-RMS soft tissue sarcoma is predominately observed in adolescents. The latter group comprises a variety of rare tumors for which diagnosis can be difficult and typically requires special studies, including immunohistochemistry and molecular genetic analysis. Current management for the majority of pediatric sarcomas is based on the data from large multi-institutional trials, which has led to great improvements in outcomes over recent decades. Although surgery remains the mainstay of treatment, the curative aim cannot be achieved without adjuvant treatment. Pre-treatment staging and risk classification are of prime importance in selecting an effective treatment protocol. Tumor resectability, the response to induction chemotherapy, and radiation generally determine the risk-group, and these factors are functions of tumor site, size and biology. Surgery provides the best choice of local control of small resectable tumors in a favorable site. Radiation therapy is added when surgery leaves residual disease or there is evidence of regional spread. Chemotherapy aims to reduce the risk of relapse and improve overall survival. In addition, upfront chemotherapy reduces the aggressiveness of the required surgery and helps preserve organ function in a number of cases. Long-term survival in low-risk sarcomas is feasible, and the intensity of treatment can be reduced. In high-risk sarcoma, current research is allowing more effective disease control. 相似文献

Soft tissue sarcomas are relatively frequent in adolescents and young adults and their clinical management may be complex, partly due to tumor associated factors, but also because different approaches have been adopted by pediatric and adult medical oncologists dealing with the same disease. However, times are changing and in the last few years, management has tended to converge towards a common strategy. Continued and increased international collaboration between pediatric and adult sarcoma groups is of critical importance to improve the quality of treatment as well as research programs dedicated to young patients with soft tissue sarcomas. 相似文献

BACKGROUND: The survival of children and adolescents with advanced (unresectable or metastatic) nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) is poor. In order to clarify the role of combining chemotherapy with aggressive local control using surgery and/or radiation, we reviewed our institutional experience with the treatment of advanced pediatric NRSTS. PROCEDURE: We reviewed the charts of all patients less than 21 years treated for an advanced NRSTS at the National Cancer Institute (NCI) between 1983 and 2003. Tumor pathology was confirmed and demographic, disease, and treatment data were abstracted. Survival was calculated using standard methods. RESULTS: Of the 25 patients who were treated over the study period, 15 had metastatic disease and 10 had unresectable or incompletely resected disease at presentation. Twenty-one patients received chemotherapy consisting of the combination of vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, and the remaining 4 received regimens that included doxorubicin. Twenty patients (80%) had a complete (5/25) or partial (15/25) response after chemotherapy alone. After the combination of chemotherapy and local control, 14 patients (56%) had a complete response (CR). The estimated 5-year overall and event-free survival (EFS) for all patients was 0.50 (standard error = 0.11) and 0.34 (standard error = 0.10), respectively. CONCLUSIONS: The combination of chemotherapy with aggressive local control in this cohort of pediatric patients with advanced NRSTS yielded results comparable to those observed in patients with advanced sarcomas that are chemotherapy responsive. Prospective randomized trials are needed to quantify the contribution of chemotherapy and to determine the ideal regimen. 相似文献

BACKGROUND: To evaluate the efficacy of interstitial brachytherapy (BRT) in children undergoing combined modality treatment for soft tissue sarcomas (STS). PROCEDURE: From September 1984 to December 2003, 50 children (median age 13 years, range 1 to 18) with STS who received BRT as part of loco-regional treatment were included. There were 30 males and 20 females, the majority (68%) had primary lesions, synovial sarcoma (32%) was the most common histological type, and 26% had high-grade lesions. Treatment included wide local excision and BRT with or without external beam radiotherapy (EBRT). Thirty children (60%) received BRT alone. RESULTS: After a median follow-up of 51 months, the local control (LC), disease-free survival, and overall survival were 82%, 68%, and 71%, respectively. LC was superior in patients with tumor size =5 cm versus >5 cm (96% vs. 67%, P = 0.04), symptom duration <2 months versus >2 months (100% vs. 73%, P = 0.05), and Grade I versus Grade II versus Grade III tumors (100% vs. 93% vs. 57%, P = 0.03). Children receiving a combination of BRT and EBRT had comparable LC to those receiving BRT alone (78% vs. 84%, P = 0.89). There was no significant difference in LC for patients receiving LDR versus HDR BRT (77% vs. 92%, P = 0.32, for BRT alone; and 67% vs. 100%, P = 0.17, for BRT + EBRT). CONCLUSION: Interstitial BRT with or without EBRT appears to result in satisfactory outcome in children with STS. Radical BRT alone, when used judiciously in select groups of children, results in excellent local control and functional outcome with reduced treatment-related morbidity. 相似文献

In the US, approximately 850–900 children are diagnosed each year with soft tissue sarcomas (STS). Key findings from recent Children's Oncology Group (COG) clinical trials include safe reduction in therapy for low risk rhabdomyosarcoma (RMS), validation of FOXO1 fusion as a prognostic factor, a modest improvement in outcome for high‐risk RMS, and a biologically designed non‐cytotoxic therapy for pediatric desmoid tumor. Planned Phase 2 trials include targeted agents for VEGF/PDGF, mTOR, and IGF‐1R for children with RMS and VEGF for children with non‐RMS STS (NRSTS). For RMS, COG Phase 3 trials potentially will explore VEGF/mTOR inhibition or chemotherapy interval compression. For NRSTS, a COG Phase 3 trial will explore VEGF inhibition.
