骨巨细胞瘤的诊断与治疗   总被引:4,自引:0,他引:4  
牛晓辉 《癌症进展》2005,3(4):316-319,398
骨巨细胞瘤是一高侵袭性良性肿瘤,主要发生于年轻人中,骨端发病.典型的影像学表现是骨端完全溶骨的膨胀性改变,多不伴有骨膜反应及软组织包块.CT及MRI可以很好地显示肿瘤的侵及范围,X线平片最具诊断意义.圆形及卵圆形基质细胞及多核巨细胞是骨巨细胞瘤的基本组织构成成分.刮除术是治疗骨巨细胞瘤的基本外科手段,但其复发率较高,应加用物理及化学的方法扩大至边缘或广泛的外科治疗边界.放疗可用于治疗难以手术的病例,但可致肉瘤变.化疗对于骨巨细胞瘤基本无效.骨巨细胞瘤的转移及恶变可能与以往治疗有关.  相似文献

Osteoclast-like giant cell tumor of the pancreas   总被引:2,自引:0,他引:2  
 A rare case of osteoclast-like giant cell tumor of the pancreas is reported. A 45-year-old woman presented with upper abdominal pain and weight loss. Examination revealed a tumor in the tail of pancreas, and distal pancreatectomy with splenectomy was performed. Pathological findings showed the tumor was composed of two cell types: atypical mononuclear round cells and abundant osteoclast-like multinucleated giant cells with central nucleoli. Immunohistochemical study showed that the atypical cells were strongly reactive for vimentin and negative for CD68, while the giant cells were immunoreactive for CD68, but negative for vimentin. The tumor was diagnosed as osteoclast-like giant cell tumor of the pancreas. We report this case and review 31 cases previously described in the literature.

Osteoclastoma-like giant cell tumor of the lung   总被引:3,自引:0,他引:3  
The main components of an unusual form of lung tumor were osteoclast-like multinucleated giant cells and mononuclear stromal cells. Besides, scattered islands of moderately differentiated squamous cells also appeared. Both the mononuclear and the osteoclast-like giant cells reacted with antibodies against CD68 and vimentin, but did not react with antibodies against cytokeratin, EMA and CEA, or lysozyme and α-1-antitrypsin. The p53 and PCNA antigens were positive only in mononuclear cells and not the osteoclast-like giant cells, suggesting that mononuclear cells represent proliferating elements with histiocytic differentiation while osteoclast-like giant cells are stromal, presumably reactive components of the tumor.  相似文献

目的:研究CD147在骨巨细胞瘤组织中的表达,探讨其与临床病理及预后的关系。方法:运用免疫组织化学S—P法,检测CD147在36例骨巨细胞瘤中的表达,分析其与肿瘤临床病理资料及Jaffe分级、En-neking分期和复发的关系。结果:CD147的阳性表达率为47.2%,阳性表达与患者性别、年龄、肿瘤发生部位等因素无关。在Jaffe分级中随着级别的增高,阳性表达率也升高,差异有显著性(P〈0.05);按Enneking分期Ⅱ、Ⅲ期阳性表达率明显高于Ⅰ期,差异有显著性(P〈0.05);复发组的CD147阳性表达率明显高于未复发组,差异明显(P〈0.05)。结论:CD147与骨巨细胞瘤的侵袭、转移密切相关,CD147可作为评价骨巨细胞瘤恶性程度和判断预后的重要指标。  相似文献

A 23-year-old woman with incomplete paralysis was operated upon for a giant cell tumor in the thoracic spine. X-ray films revealed a destruction lesion in the vertebral body of the 12th thoracic vertebra. On the plain thoracic computed tomography scan, the finding was a soap-bubble appearance with a linear high density area in the mass lesion which destroyed the vertebral body. Preoperative angiography showed no apparent feeding artery to the tumor tissue; preoperative myelography showed incomplete block at the level of the 12th thoracic vertebra. A radical operation was carried out in one stage via a combined antero-posterior approach. In order to give radiotherapy immediately after operation, a vascular pedicled rib graft was made. This paper discusses the role of thoracic computed tomography scan in the diagnosis of giant cell tumor and the surgical techniques used in treatment.  相似文献

本文对骨巨细胞瘤(GCT)的传统组织学分级与其生物学行为不甚相符的原因进行了研究。采用51例GCT为研究对象,以13例骨囊肿(良性)和15例骨肉瘤(恶性)为对照组,采用图像分析仪(IAT)对细胞核(GCT取基质细胞核),进行了形态计量研究(8项参量),DNA含量,DNA倍体类型研究,及术后复发病例的DNA倍性与其传统分级的比较研究。结果经统计学处理发现GCTⅠ级和Ⅱ级之间无显著差别,且它们的生物学属性在潜在恶性和低度恶性范畴。研究还揭示GCT的DNA≥5c细胞数超过7%者系术后复发、转移的高危病例。  相似文献

We investigated the clinical features of soft-tissue recurrence in giant cell tumor of bone (GCTB). Among 106 cases with GCTB in our hospital, there were 2 cases occurring soft-tissue recurrence which histories were reported. These two soft-tissue recurrences occurred with the interval of 6.9 years and 2.5 years respectively from primary diagnosis. The clinical presentation was nonspecific masses in soft tissue. Radiographic ossification was not found at periphery or within the masses. Through pathological examination peripheral ossification was found in 1 case and malignant transformation occurred in the other case. Through retrieving and reviewing literatures in PubMed, 19 cases of soft-tissue recurrence with detailed materials were collected and analyzed. Soft-tissue recurrence of GCTB is a rare episode which reflects its locally aggressive nature, the reasons of which are tumor cells implantation and tumor residual. Ossification at periphery or in the masses can be considered as a pathognomonic character of this episode in radiographic and pathohistological examination. The prevention lies in determining tumor extension preoperatively, proper non-tumor manipulations, removing the tumor and irrigating operative wound as completely as possible.  相似文献

Giant cell fibroblastoma (GCF) is a rare soft tissue tumor most often discovered during the first two decades of life. We present a case of a 3- year- old boy with a history of a recurrent lesion in the knee, the tumor growth progressively and enlarged to 2.1 cm in the previous two years before diagnosis. It involved the subcutaneous tissue, had infiltrative borders and extended into the superficial dermis. The tumor was surgically excised with free margins. There was no evidence of local recurrence, and a metastatic workup was negative after 10 years of follow up. We review herein the clinicopathologic features, histogenesis, differential diagnosis and relationship to dermatofibrosarcoma protuberans (DFSP).  相似文献
