Giant cell tumor of bone (GCT) is a locally osteolytic tumor with variable aggressiveness. In rare cases, pulmonary metastasis can be observed. The lesion most frequently occurs in the epiphysis of long tubular bones of the knee region, predominantly affecting young adults after closure of the growth plate. The characteristic histological appearance of GCT displays a high number of osteoclast-like multinucleated giant cells, which resulted in the classification "osteoclastoma" or "giant cell tumor". Apart from the multinucleated giant cells, there are two mononuclear cell types in GCT. The first one has a round morphology and resembles monocytes. The second cell type is the spindle-shaped, fibroblast-like stromal cell. Cell culture experiments with GCT cells revealed the stromal cell to be the proliferating component of the GCT. The other two cell types, the monocyte and the multinucleated giant cell, were lost after a few cell culture passages. Furthermore, latest results from GCT reveal that the stromal cells secrete a variety of cytokines and differentiation factors, including MCP1, ODF, and M-CSF. These molecules are monocyte chemoattractants and are essential for osteoclast differentiation, suggesting that the stromal cell stimulates blood monocyte immigration into tumor tissue and enhances their fusion into osteoclast-like, multinucleated giant cells. The multinucleated giant cell itself resembles a normal osteoclast that is able to resorb bone leading to extended osteolysis. This new model of GCT genesis supports the hypothesis that the stromal cell is the neoplastic component whilst the monocytes and the multinucleated giant cells are just reactive components of this tumor. Taking this into consideration, the nomenclature of the "giant cell tumor" needs to be reconsidered. 相似文献

Background Although the recurrence rate of giant cell tumors of bone (GCTB) is relatively high exact data on treatment options for the
recurrent cases is lacking. The possible surgical procedures range from repeated intralesional curettage to wide resection.
Methods Two hundred and fourteen patients with histologically certified GCTB have been treated at the authors department from 1980
to 2007. Sixty-seven patients with at least one local recurrence were included in this study. The mean follow-up was 77.3 months.
The data was evaluated according the re-recurrence rate with regard to the surgical procedure for the recurrence.
Results The mean time until the first local recurrence was 22.0 months; the mean number of recurrences per patient was 1.4. The recurrence
occurred in 69.7% (46 out of 66 patients) within the first 2 years. If after intralesional procedures (curettage or intralesional
resection) no adjunct was used the re-recurrence rate was 58.8% (10 out of 17 patients) and decreased to 21.7% (5 out of 23
patients) if a combination of all adjuncts (PMMA + burring) was used. The likelihood of re-recurrence was reduced by the factor
5.508 which was clearly significant (P = 0.016). In case of wide resection no re-recurrence occurred. Seven patients (10.5%) developed pulmonary metastases. Fourteen
patients (20.9%) finally received an endoprosthesis; 12 due to tumor recurrence, 2 due to secondary arthritis.
Conclusion Recurrent GCTB can be treated by further curettage with additional burring and cementing with an acceptable re-recurrence
rate of 21.7%. The rate of patients finally needing an endoprosthesis is 20.9%. Due to the high rate of pulmonary metastases
recurrent GCTB may be considered as a severe disease.

Giant cell tumor of the pancreas arising in the ovarian-like stroma of a mucinous cystadenocarcinoma 总被引:1,自引:0,他引:1
Simon Bergman L. Jeffrey Medeiros Tina Radr D. Charles Mangham Kent B. Lewandrowski 《Journal of gastrointestinal cancer》1995,18(1):71-75
Summary We describe a malignant mucinous cystic neoplasm of the pancreas with ovarian-like stroma within which an osteoclast-like
giant cell rich tumor arose. This rare tumor had a unique immunohistochemical profile with the giant cells staining for vimentin,
leukocyte common antigen, and the monocyte/macrophage marker CD68, whereas the mucinous epithelium stained for epithelial
membrane antigen and cytokeratin. The immunohistochemical findings are consistent with two lines of differentiation, one epithelial
and the other suggesting mesenchymal differentiation of the giant cell tumor with an immunophenotype similar to giant cell
tumor of bone. The coexistence of these two rare tumors suggests that they are histogenetically related. The finding of a
giant cell tumor arising in the ovarian stroma indicates that the stroma of mucinous tumors is not always an innocuous component
of the tumor. 相似文献

Introduction:Giant cell tumor (GCT) of the bone is a benign–malignant intermediate tumor with locally destructive growth and a relatively high local recurrence rate. Neurological symptoms may develop in patients with GCT of the spine, and surgical treatment is prioritized in cases where resection is possible. However, the local recurrence rate of GCT of the bone is higher than that of GCT at other sites owing to the associated surgical challenges, and treatment is often difficult. No study to date has reported long-term remission of recurrent tumors for more than 5 years by treatment with carbon ion beam radiotherapy after resection of GCT of the cervical spine.Patient concerns:A 14-year-old boy who experienced recurrence after surgery for GCT of the cervical spine.Diagnosis:The patient presented with cervical pain, and computed tomography revealed a mass of the C2 vertebral body. He underwent surgery for tumor resection and autologous bone grafting, and the final pathological diagnosis was GCT. The transplanted bone exhibited gradual progression of resorption, and recurrent tumors were observed on computed tomography and magnetic resonance imaging 1 year and 4 months after surgery.Interventions:The patient was started on denosumab at 15 years of age and received carbon ion beam therapy with 70.4 Gy administered in 32 sessions over 7 weeks.Outcomes:No progressive tumor growth was observed, there were no neurological symptoms such as paralysis or pain were noted, and the patient was in remission for 5 years after irradiation.Conclusion:These findings suggest that carbon ion radiotherapy is a safe and effective therapeutic option for patients with recurrent GCT of the cervical spine. 相似文献

Giant cell tumor of tendon sheath (GCTTS) and Wegener’s granulomatosis (WG) are rare conditions both characterized by polyclonal
cellular proliferation and multinucleated giant cells formation. Here, we report the case of a 27-year-old Caucasian woman
affected by WG who experienced the metachrone appearance of two different GCTTSs at the right hand within a time of 3 years.
To our knowledge, the combination of GCTT with WG is exceptional and this could probably be the first case reported. The subsequent
appearance of two rare diseases both characterized by giant cell formation apparently points to similarities in their pathogenesis.
However, at present no pathogenic relationship between GCTTS and WG is demonstrable and their simultaneous occurrence has
to be considered coincidental. Actually, an emerging opinion is to consider GCTTS as a mixed lesion in which both tumoral
and non-tumoral inflammatory cells play a central pathogenic action. On this view, the proposed case could support the evidence
about the crucial role of a chronic inflammatory injury in enhancing GCTTS appearance. 相似文献

There is no consensus on a treatment strategy for spinal giant cell tumor of bone (GCTB) because of the difficulty in their treatment. Treatment options often include the use of the controversial denosumab, an antibody therapy aimed at tumor shrinkage, different curettage techniques, resection, or a combination of these therapies. The current study aimed to identify treatment methods associated with favorable outcomes in patients with spinal GCTB.We retrospectively reviewed 5 patients with spinal GCTB, including patients with tumors of the sacrum, treated at our hospital between September 2011 and November 2020. Two men and 3 women were included in the study. The median follow-up period was 74 months (range: 14–108 months). We surveyed the tumor site, treatment method, denosumab use, and outcomes.The median age was 17 years (range: 17–42 years). There were 2 cases of sacral GCTB and 1 case each of lumbar, cervical, and thoracic vertebral GCTB. The comorbidities observed included hepatitis, malignant lymphoma, atopic dermatitis, and asthma. The treatment method included zoledronic acid after embolization and denosumab, denosumab only, curettage and posterior fusion, and curettage resection after embolization and anterior and posterior fusion. Denosumab was used in all cases. Three patients were continuously disease-free, 1 patient with no evidence of disease, and 1 patient alive with disease.Aggressive treatment, especially surgical treatment, may lead to good results in spinal GCTB. 相似文献

Background and Aim: Magnetic activated cell sorting (MACS) and fluorescent activated cell sorting (FACS) were employed to enrich and detect the gastric cancer cells from a cell line in a model system, and to enrich and detect disseminated tumor cells (DTCs) from bone marrow (BM) of patients with gastric cancer. Methods: Fifteen patients with benign gastric lesions and 35 patients with gastric cancer who received curative operations between December 2002 and June 2003 were selected. Mononuclear cells were separated from their BM. Cells from cell line OCUM‐2M were seeded with 10‐grade ratio into mononuclear cells from patients with benign gastric lesion. After labeling by MACS minibeads conjugated with cytokeratin (CK) 7/8 antibodies, anti‐CK‐fluorescein isothiocyanate (FITC), and anti‐CD45‐perdinin chlorophyll protein (PerCP), the samples were enriched twice using an MS+/RS+ positive separation column. The FACS analysis was conducted on these samples before and after MACS enrichment. The results were analyzed using clinopathological parameters. Results: Disseminated tumor cells were detected in the BM of 25 (71.43%) patients with gastric cancer. The frequencies of DTCs were 1.38 × 10?8–2.40 × 10?5, 2.19 × 10?7–3.70 × 10?5, 4.01 × 10?6–8.57 × 10?5 in patients with well, moderately, and poorly differentiated carcinoma, respectively (P = 0.026). Disseminated tumor cells in BM had close correlation with tumor tumor‐node‐metastasis (TNM) stage (P = 0.034) and cancer‐free survival (P = 0.035). Conclusion: Disseminated tumor cells are very common in the BM of gastric cancer patients. Poor histological differentiation and more advanced TNM stage have more DTCs in the BM of gastric cancer patients. Patients with DTCs tend to have a poor prognosis. 相似文献

Summary Seven giant cell tumors of bone and four malignant fibrous histiocytomas were studied immunohistochemically with different monoclonal antibodies to the mononuclear phagocyte system (MPS), to HLA-DR antigens, and to a proliferation-associated nuclear antigen (KI-67), in order to clarify the role of macrophages in these tumors. A part of the mononuclear cells stained positive with antibodies against the MPS. Antibody 25-F-9 against mature tissue macrophages showed the strongest reaction. The osteoclast-like giant cells also stained positive with this antibody. Fibroblast-like stromal cells, however, showed negative reactions to all antibodies against MPS cells. A double-labeling immunohistological technique was used to detect the proliferating cell population in these tumors. The fibroblast-like cells that were negative for MPS markers, were positively labeled with the monoclonal antibody Ki-67 against a proliferation-associated nuclear antigen, whereas a negative reaction to Ki-67 was seen in cells positive with antibodies to the MPS. These results support the concept that macrophages are a reactive population in these tumors, whereas the fibroblast-like mesenchymal cells are the proliferating tumor cells.Supported by Deutsche Forschungsgemeinschaft, grant no. 648 1/2 相似文献

Giant cell tumor of bone is a rare but aggressive benign tumor that arises at the end of long tubular bones. The tumor rarely metastasizes; however, we report a case in which a giant cell tumor of bone presented with progressive pulmonary metastases. There has been no clear pathologic evidence of the definitive cause or route of metastasis. In our case, the primary tumor site was located in the left femur with pathological evidence of blood vessel invasion. The histological and pathological features of this entity are discussed in this letter to the editor. 相似文献

AIM: To clarify the biological feature contributing to gastric cancer with diffuse bone metastases at diagnosis.METHODS: The participants visited the Department of Clinical Oncology, Akita University Hospital, from January 2014 to August 2015. The selection criterion for gastric cancer with diffuse bone metastases at diagnosis includes over 29 hot spots of bone scintigraphy. Circulating tumor cell were collected from 20 m L of peripheral venous blood drawn using a Cell Search kit and a Cell Tracks Auto Prep system by SRL, a clinical laboratory. The endpoints of this study were correlations between circulating tumor cells(CTC) count and therapeutic outcomes. RESULTS: Among 39 patients with gastric cancer, 5 patients met the criterion. The incidence of this subtype was 12.8%. CTC counts ranged from 235 to 6440 cells/7.5 m L of peripheral blood(median of 1724). These values were much higher than common gastric cancers(2 cells). In chemo-sensitive cases, CTC counts decreased within 14 d(median) from 275, 235 and 1724 to 2, 7 and 66, respectively. On the other hand, CTC counts increased after treatment failure or insensitive case from 2, 7 and 6440 to 787, 513 and 7885, respectively. The correlation between CTC count and survival time showed a trend, but did not reach significance(Y = 234.6- 0.03 X, P = 0.085).CONCLUSION: High CTC count is a biological hallmark of this subtype, and can be used as a direct and definitive indicator of therapeutic outcome. 相似文献

AIM: To investigate the clinical presentation,diagnosis,and treatment of giant colonic diverticulum(GCD,by means of a complete and updated literature review).GCD is a rare manifestation of diverticular disease of the colon.Less than 200 studies on GCD were published in the literature,predominantly case reports or small patient series.METHODS: A systematic review of the literature was performed using the Embase and PubM ed databases toidentify all the GCD studies.The following MESH search headings were used: "giant colonic diverticulum"; "giant sigmoid diverticulum".The "related articles" function was used to broaden the search,and all of the abstracts,studies,and citations were reviewed by two authors.The following outcomes were of interest: the disease and patient characteristics,study design,indications for surgery,type of operation,and postoperative outcomes.Additionally,a subgroup analysis of cases treated in the last 5 years was performed to show the current trends in the treatment of GCD.A GCD case in an elderly patient treated in our department by a sigmoidectomy with primary anastomosis and a diverting ileostomy is presented as a typical example of the disease.RESULTS: In total,166 GCD cases in 138 studies were identified in the literature.The most common clinical presentation was abdominal pain,which occurred in 69% of the cases.Among the physical signs,an abdominal mass was detected in 48% of the cases,whereas 20% of the patients presented with fever and 14% with abdominal tenderness.Diagnosis is based predominantly on abdominal computed tomography.The most frequent treatment was colic resection with en-bloc resection of the diverticulum,performed in 57.2% of cases,whereas Hartmann's procedure was followed in 11.4% of the cases and a diverticulectomy in 10.2%.An analysis of sixteen cases reported in the last 5 years showed that the majority of patients were treated with sigmoidectomy and en-bloc resection of the diverticulum; the postoperative mortality was null,morbidity was very low(1 patient was hospitalized in the intensive care unit for postoperative hypotension),and the patients were discharged 4-14 d after surgery.CONCLUSION: Giant colonic diverticulum is a rare manifestation of diverticular diseases.Surgical treatment,consisting predominantly of colonic resection with en bloc resection of the diverticulum,is thepreferred option for GCD and guarantees excellent results. 相似文献

Malignant giant cell tumor of bone (MGCTB) accounts for 0.07% of all cases of primary bone tumor. The rarity and complexity of this tumor give rise to some arguments about its histological differentiation, diagnosis, treatment and prognosis. In this paper, we present a 57-year-old man who has a large MGCTB in his rib with lung-targeted metastasis at the time of initial diagnosis. He underwent an operation followed by radiotherapy. The man has been free of recurrence or metastasis for 18 months. 相似文献
