目的:分析导致软组织肉瘤非计划切除的原因并探讨避免软组织肉瘤非计划切除的策略。方法:自2009年10月至2012年12月新疆医科大学第一附属医院骨科中心骨病骨肿瘤科收治的105 例软组织肉瘤患者资料,其中男性65例,女性40例,平均年龄52岁;接受计划性软组织肉瘤切除术患者82例(计划手术组),曾于外院接受非计划切除术的软组织肉瘤患者23例(非计划手术组)。 计划手术组患者行广泛切除及根治切除术,非计划手术组患者行扩大切除术。统计分析两组患者一般情况、病灶位置及大小、手术边界、肿瘤复发转移情况,并比较两组患者生存期。结果:非计划手术组达到广泛切除边界的比例明显低于计划手术组(P<0.05)。 非计划手术组患者3 年生存率明显低于计划手术组(P=0.001)。 非计划手术组平均随访18个月(3~36个月),12例死亡(52.2%),其中9 例(39.1%)死于肿瘤转移,3 例死于其他疾病;计划手术组平均随访23个月(5~36个月),15例(18.3%)死亡,其中12例(14.6%)死于肿瘤转移,3 例死于其他疾病。结论:与计划手术相比,软组织肉瘤非计划切除常导致手术范围不足、肿瘤复发转移的风险,可能增高肿瘤所致的死亡率。临床医生应尽量避免非计划切除手术的发生。 相似文献

目的探讨软组织肉瘤患者非计划手术后的再手术切除及其治疗效果。方法回顾性分析44例已行非计划手术的软组织肉瘤患者行二次扩大切除术的复发、转移及生存情况等治疗效果。结果二次手术前无复发组共17例,2例在术后出现局部复发(11.8%),1例淋巴结转移并带瘤生存(5.9%),1例肺转移死亡。二次手术前已复发组共27例,13例在术后出现局部复发(48.1%),8例肺、肝或多发转移(29.6%),7例肺、肝或多发转移而死亡。两组的二次复发情况有显著性差异(P=0.021);转移情况无显著性差异(P=0.121)。患者在二次手术前是否复发及二次手术后是否复发对所有患者的总体生存情况影响无显著差异(P0.05);两组患者总的5年无病生存率分别为86.3%±9.2%及40.3%±10.1%,有显著差异(P=0.003)。结论软组织肉瘤的局部复发对肿瘤的转移率及患者的总体生存率无明显影响,但会明显降低患者的无病生存率。软组织肉瘤一旦诊断明确应及时行二次扩大切除术治疗。 相似文献

15例腺泡状软组织肉瘤临床特点及预后分析 总被引:2,自引:0,他引:2
背景与目的:腺泡状软组织肉瘤(alveolar soft part sarcoma,ASPS@是一种罕见的恶性软组织肿瘤,生长缓慢,无典型临床症状,常伴有远处转移(肺转移,脑转移及骨转移等@。本文旨在研究腺泡状软组织肉瘤的临床特点,评估其预后因素。方法:回顾性研究了2003年1月-2008年12月就诊于北京大学人民医院骨与软组织肿瘤治疗中心的15例腺泡状软组织肉瘤患者的临床资料,并随访了他们的预后情况。15例患者中,女性9例,男性6例;小于或等于30岁者8例,大于30岁7例;肿瘤大于5cm者11例,小于5cm者4例;原发于软组织12例,原发于骨骼3例;未见其他部位转移6例,肺转移6例,骨转移3例,脑转移2例;术后局部复发2例;术后9例接受放疗,6例未接受放疗;术后接受化疗11例,未接受化疗4例,化疗方案MAID:多柔比星,氮唏米胺及异环磷酰胺。结果:患者预后情况较差,其中无瘤生存6例,带瘤生存4例,死亡5例,中位生存时间为42.0个月,5年生存率为41.7%。伴有远处转移(肺转移、脑转移及骨转移@的患者5年生存率远低于整体生存率。患者个人性别、年龄对预后无显著性差异。肿瘤大小、部位及有无远处转移是影响预后的重要因素。结论:腺泡状软组织肉瘤是高度恶性软组织肿瘤。尽早评估病情,制定合适的治疗方案,原发病灶采取广泛切除,以降低复发及转移风险。但由于本组数据较少,放化疗是否有效还需进一步研究。 相似文献

目的探讨补充广泛切除术在软组织肉瘤外科治疗中的意义。方法回顾性分析1998年1月至2005年10月收治的外院误诊为良性肿瘤而行局部切除的软组织肉瘤患者58例,均行补充广泛切除手术治疗。结果术后病理标本切除缘评价5cm者14例;3cm者32例;3cm以下者12例。首次术后肿瘤残存26例,占45%。补充广泛切除术后有28例需要行软组织修复重建。补充广泛切除手术后随诊10~94个月,8例复发,12例转移,死亡9例。均为高度恶性软组织肉瘤。Kaplan—Meier法计算5年生存率为84.5%,局部复发率为14%。切除缘的5年生存率3cm以上组和3cm以下组之间无显著性差异。局部复发率3cm以上组和3cm以下组有显著性差异(P〈0.05)。结论补充广泛切除术是误诊软组织肉瘤最主要的治疗手段,补充广泛切除的标准切除缘的制定是今后的研究课题。缩小切除缘,可以改善预后,减少组织缺损所造成的修复重建。 相似文献

BACKGROUND AND PURPOSE: For soft tissue sarcomas (STS), some patients undergo an "unplanned surgery," non-oncologic resection for presumed benign tumor. The treatment of choice, in such cases, is re-excision combined (if indicated) with radiation. However, there are clinical situations when treatment by radiation alone is recommended. Here results of such an approach are assessed. MATERIALS AND METHODS: Seventy-eight patients irradiated after unplanned surgery between 1970 and 1997 were identified from the MGH institutional database. Surgical margins were inevaluable in 50 (64%) and 28 (36%) had positive margins. Tumor characteristics: location, lower extremity (63%), upper extremity (27%), other (10%); median tumor size, 5 cm; grade-G1 (19%), G2 (49%), G3 (32%); AJCC stage (2002)-I (19%), II (54%), III (27%). Median radiation dose given was 66 Gy (range: 51-88). RESULTS: With a median follow-up of 10 years, estimated local control rate was 88% and 86% at 5 and 10 years, respectively. Distant control rate was 80% at 5 and 10 years. Depth in the relation to the fascia, tumor size, and AJCC stage significantly influenced local recurrence- and distant metastasis-free survival. Ten major radiotherapy complications occurred from 1 to 21 years after treatment. CONCLUSIONS: Despite convincing data about the necessity for re-excision after unplanned surgery for STS, these results demonstrate that radiation therapy alone can be an effective alternate for those patients in whom functional or medical considerations preclude further surgery. The risk for potential radiation therapy complications, however, must also be considered in the treatment decision. 相似文献

BackgroundUnplanned excisions of soft tissue sarcomas are still not infrequent events with patients presenting to referral Centers after having received an inadequate surgical treatment. In literature, both the wait-and-see policy and the “aggressive” management with a re-excision have been advocated. The purposes of this study were to analyze the incidence of detectable residual tumor in surgical specimens following a re-excision and to verify the long-term results of patients treated with a re-excision after previous unplanned excision.MethodsWe retrospectively evaluated 131 patients affected by localized soft tissue sarcoma (95 high grade; 36 low grade) of the limbs or the superficial trunk treated at our Institution, from 2000 to 2013, with a re-excision after a previous unplanned inadequate excision. Site, size, depth, histotype, grade, adjuvant therapies, time from unplanned surgery to re-excision were recorded and evaluated in association with clinical results. We specifically evaluated the disease-specific survival, local recurrence free survival, distant metastases free survival and the event free survival.ResultsMean follow-up for living patients was 10.9 years (median 11.2 years), with a follow-up ranging from 14 to 227 months. 34% of patients underwent a re-excision within the first 2 months after unplanned surgery, while 66% of patients at more than 2 months. Residual detectable tumor cells were found on histological examination in 54% of re-excisions. A wide margin was obtained in 123 cases, a persisting positive margin in 8 patients.Disease-specific survival was 93.5%, 91.6% and 89.6% at 5, 10 and 15 years for whole series and 90.9%, 88.2% and 85.7% for high grade tumors. Event-free survival in patients affected by high grade tumors rated 75.0% at 5 years, 72.4% at 10 years and 72.4% at 15 years. Local recurrence free survival in high grade tumors was 87.6%, 86.2% and 86.2% at 5, 10 and 15 years.The grade of the tumor (high grade) and the initial dimension of the tumor (≥5 cm) were associated with worst survival. High grade tumor impacted negatively also on local recurrence free survival and event free survival. Instead, the initial size of the tumor significantly affected the event free survival but not the local recurrence free survival. No significant differences of outcome were found analyzing tumor depth, time interval to re-excision, presence of residual tumor or margins.ConclusionBased on our results and literature findings, we believe that surgeons should offer a re-excision procedure in those patients presenting with an inadequate excision of a high grade soft-tissue tumor, in particular with tumors larger than 5 cm before excision. Indeed, if an adequate second treatment is performed with surgery ± radiotherapy, the long-term results of patients receiving a re-excision after unplanned excision of a high grade soft tissue sarcoma seem to be comparable to the results generally reported for wide primary excisions. More debatable is whether to perform a re-excision or not in patients with low-grade tumors. Perhaps, in this latter group a wait and see policy can eventually be offered as well as in high grade tumors when a re-excision procedure could involve major surgery or significantly affect postoperative function. 相似文献
