脊索瘤是一种较为少见的中低度恶性的原发性骨肿瘤,占原发恶性骨肿瘤的1%-4%。脊索瘤起源于胚胎残余脊索组织,好发于脊柱中轴的两端,其中骶尾部占40%-50%,颅底部占35%-40%,只有少数发生于其余椎体占15%-20%。脊索瘤起病隐匿,生长缓慢,多见于50-70岁,  相似文献

脊索瘤是一种低度恶性肿瘤,起源于胚胎残余脊索组织,由星形细胞和液滴细胞组成,呈小叶状分布,小叶间有纤维间隔。1894年被Ribbert命名,几乎均发生在脊柱。脊索瘤占恶性骨肿瘤的4%,约50%的脊柱脊索瘤发生于骶骨,多数在40~70岁之间发病,偶见于儿童和青年[1~3]。由于骶骨脊索瘤早期症状隐匿,骶骨部位解剖关系复杂,临床发现时肿瘤常较大或已侵犯骶神经,给治疗带来很大困难[4、5]。笔者对最近几年的文献进行检索,综述如下。1发病特点骶骨脊索瘤生长较为缓慢,局部侵犯性强,较少发生远处转移[6、7]。Bergh[8]对39例骶骨脊索瘤病人行CT和MRI检查,…  相似文献

目的 探讨颈椎脊索瘤的临床特点及外科治疗方法与疗效。方法 对1989年至2006年接受手术治疗的8例颈椎脊索瘤患者的临床资料进行回顾性分析。男5例,女3例;年龄34-72岁,平均53.8岁。依据肿瘤的WBB分期,实施次全或全椎体切除术3例,矢状切除术2例,次全或全脊椎切除术2例,颈椎管内脊索瘤囊外摘除术1例。脊柱稳定性重建术中,取自体髂骨植骨5例,钛网内骨水泥填塞前路椎体支撑2例。术后行辅助放疗。结果 患者术后神经根性刺激症状较术前明显缓解或消失,颈髓压迫症状多有1-2个级别以上的改善。术后病理检查均可见典型“Physaliphorous细胞”。随访3~120个月,平均43.5个月。内固定物融合良好,植骨融合率100%。肿瘤局部复发4例,1例死于肿瘤复发后的高位截瘫并发症,全脊椎切除者未见复发迹象。7例未见远处转移,1例颈椎管内脊索瘤者既往有骶骨脊索瘤手术史,故考虑为原发骶骨脊索瘤继发硬膜下转移。结论 颈椎脊索瘤临床相对少见,早期症状不典型,诊断应重视CT和MR检查。全脊椎切除术结合术后局部放疗可降低局部复发率。  相似文献

Chordoma is a relatively rare, locally aggressive tumor which is known to arise from embryonic remnants of the notochord and to occur exclusively along the spinal axis, with a predilection for the sacrum. Although chordoma typically presents as a single lesion, a few cases of metastasis have been reported and the prognosis of such patients may be poor. Chordomas are slowly growing tumors with insidious onset of symptoms, making early diagnosis difficult. Recent improvements in imaging have provided valuable information for early diagnosis. The optimal treatment for sacral chordoma is en bloc sacral resection with wide surgical margins. Improvement in surgical techniques has widened the opportunities to provide effective treatment. However, the effects of adjuvant treatment options are still both unclear and controversial. Substantial progress has been made in the study of molecular‐targeted therapy. The authors review the current surgical and adjuvant treatment modalities, including molecular‐targeted therapy, available for management of sacral chordoma.  相似文献

INTRODUCTION

Chordomas are rare but aggressive tumors due to local recurrence and distant metastases. They originate commonly in the sphenooccipital and sacrococcygeal regions, and metastasize to the lungs, bone, skin, liver, and lymph nodes. They occur more frequently in men and people over the age of 40.

PRESENTATION OF CASE

A 28 year-old female presented with sacrococcygeal chordoma for which she received wide local excision and adjuvant radiation therapy. She enjoyed an unusual disease-free survival for 11 years until a routine surveillance scan of the pelvis identified local recurrence. Further work up revealed bilateral pulmonary metastases. She underwent local excision of the recurrent tumor and video-assisted thoracoscopic (VATS) wedge resection of pulmonary metastases. She also received adjuvant radiation therapy to the recurrent resection bed. Two years later, she remains free of disease and symptoms.

DISCUSSION

Chordomas are commonly insensitive to chemotherapy and radiation, making surgery the most successful therapeutic modality. However, there are few guidelines on the surveillance and treatment of recurrent chordoma. We report success with aggressive surgical resection of recurrence and metastasis as well as adjuvant radiation therapy.

CONCLUSION

The prolonged survival of our patient underscores the importance of (1) aggressive surgical resection of chordoma, whether primary, recurrent, or metastatic, with adjuvant radiation therapy, (2) minimization of surgical seeding of tumor, and (3) diligent cancer surveillance.  相似文献

三阴性乳腺癌是一类特殊类型的乳腺癌,由于缺乏治疗靶点,化疗是目前主要的治疗方法。三阴性乳腺癌患者接受新辅助治疗并获得病理完全缓解,则预后明显改善。目前三阴性乳腺癌新辅助治疗方案仍以蒽环类药物和紫杉类药物化疗为主,但随着对三阴性乳腺癌分子本质认识的深入,新辅助治疗方案不断地获得探索和优化,包括铂类药物的优化,免疫检查点抑制剂、多聚二磷酸腺苷核糖聚合酶抑制剂的使用,均获得较好效果。  相似文献

Background Context

Sacral chordoma is a rare entity with high local recurrence rates when complete resection is not achieved. To date, there are no series available in literature combining surgery and intraoperative radiotherapy (IORT).

Purpose

The objective of this study was to report the experience of our center in the management of sacral chordoma combining radical resection with both external radiotherapy and IORT.

Study Design

This is a retrospective case series.

Patient Sample

The patient sample included 15 patients with sacral chordoma resected in our center from 1998 to 2015.

Outcome Measures

The outcome measures were overall survival (OS), disease-free survival (DFS), and rates of local and distant recurrences.

Methods

We retrospectively reviewed the records of all the patients with sacral chordoma resected in our center from 1998 to December 2015. Overall survival, DFS, and rates of local and distant recurrences were calculated. Results between patients treated with or without IORT were compared.

Results

A total of 15 patients were identified: 8 men and 7 women. The median age was 59 years (range 28–77). Intraoperative radiotherapy was applied in nine patients and six were treated with surgical resection without IORT. In 13 patients, we performed the treatment of the primary tumor, and in two patients, we performed the treatment of recurrence disease. A posterior approach was used in four patients. Wide surgical margins (zero residue) were achieved in six patients, marginal margins (microscopic residue) were achieved in seven patients, and there were no patients with intralesional (R2) margins. At a median follow-up of 38 months (range 11–209 months), the 5-year OS in the IORT group was 100% versus 53% in the group of non-IORT (p=.05). The median DFS in the IORT group was 85 months, and that in the non-IORT group was 41 months. In the group without IORT, two patients died and nobody died during the follow-up in the group treated with IORT. High–sacrectomy treated patients had a median survival of 41 months, and low–sacrectomy treated patients had a median survival of 90 months. Disease-free survival in patients without gluteal involvement was 100% at 5 years, and that in patients with gluteal involvement was 40%. All patients with a recurrence in our study had gluteal involvement.

Conclusions

Multidisciplinary management of sacral chordoma seems to improve local control. The use of IORT, in our experience, is associated with an increase in OS and DFS. The level of resection and gluteal involvement seems to affect survival. The posterior approach is useful in selected cases. Multicenter studies should be performed to confirm the utility of IORT.  相似文献
