The karyotype of a mouse trapped in a hybrid zone between a Robertsonian (Rb) population (2n=22) and a population with the standard karyotype (2n=40-all-telocentrics) shows two Rb chromosomes with new arm compositions. We suggest that whole-arm reciprocal translocations between Rb chromosomes gave rise to the new chromosome constitution and that such events can greatly help in understanding house mouse karyotype diversification and chromosomal speciation. 相似文献

Summary The authors report on two groups of patients (each with 12) with primary bone tumors of the humerus who underwent either a classical Tikhoff-Linberg (T-L) procedure or a modified technique by which the body of the scapula was saved. The latter procedure was an en bloc resection of the glenohumeral joint after an extra-capsular osteotomy of the neck of the scapula, followed by reconstruction with a modular prosthesis. Indications, perioperative differences, and complications of both procedures are discussed. Besides producing better aesthetic and functional results, the modified technique offered the advantages of shorter anesthesia time, less blood loss, and a better anchorage of the prosthesis. The results of this study show that the proposed modification of the T-L procedure is indicated in patients with bone tumors of the proximal humerus in which invasion of the joint capsule is present without macroscopic involvement of the glenoid.Supported in part by Special Project Oncology, National Council for Research, grant no. 87.02810.44 相似文献

Massive bone allograft reconstruction in high-grade osteosarcoma 总被引:18,自引:0,他引:18

From 1986 to 1994, 112 bone allograft reconstructions were performed in patients with high-grade osteosarcoma in whom neoadjuvant chemotherapy was administered. The allograft reconstruction was used in arthrodesis in 44 cases (41 knees, three ankles), as an intercalary graft in 39 (28 femurs, 11 tibias), as an osteoarticular graft in 22 (three proximal and/or distal humeri, six distal femurs, 13 proximal tibias), and as an allograft and prosthesis composite in seven (two proximal humeri, one proximal femurs, four proximal tibias). In 20 patients an autologous vascularized fibula was used to augment the allograft. Functional results were excellent or good in 74% of the patients after the primary surgery, and in 83% of the patients after secondary surgery. Complications include delayed union (49%) and fracture (27%), although there were no cases of deep infection. The incidence of delayed union, but not infection or fracture, was increased by the use of chemotherapy. 相似文献

Vascularised fibular grafts (VFGs) are widely used for primary reconstruction of long bones after bone tumour resections. The biological properties of VFGs are such that they can be a useful option even in failed intercalary reconstructions. The purpose of the current study was to investigate the results and the morbidity of VFGs as a salvage procedure in failed previous reconstructions after intercalary bone tumour resection of the femur. Our series included 12 patients, treated from April 1989 to March 2005, with an average age of 23 years (range 10–43 years) at presentation. The initial diagnosis was osteosarcoma in 10 cases and Ewing's sarcoma in two cases. All patients received chemotherapy and none received radiation therapy. Seven patients received VFG as biologic augmentation in intercalary allograft non-union and in the other five patients, a combination of allograft and VFG was used to replace a cement spacer with hardware failure (four patients) and a failed intercalary prosthesis (one patient). Three patients died during follow-up, in all cases because of metastatic disease. At an average follow-up of 147 months (range 11–260 months), the remaining nine patients were continuously disease-free. Complete healing of the osteotomy of both allograft and VFG was observed in 10 patients at final follow-up. Two major complications were observed that required surgical revision, eventually healing in one case and leading to a poor functional outcome in one case. Significant hypertrophy of the VFG was detected in seven of nine evaluable patients. At final follow-up the mean Musculoskeletal Tumour Society (MSTS)’93 functional score of the nine evaluable patients was 90% (range 66–100%). These results indicate that VFG is a valid salvage procedure in failed intercalary reconstructions of the femur after bone resection. 相似文献

A series of five cases of sacral aneurysmal bone cyst is presented. There were three females and two males, the youngest patient being 11 years old, the oldest 41 years old. All patients had pain of long duration with varying signs of nerve root compression. Three patients had micturitional problems. Four patients had a palpable mass which was tender. All had standard radiographs. Tomograms, computed tomography (CT) scans or MRI (magnetic resonance imaging) were obtained in some patients. In all patients a definite histologic diagnosis was established. Four lesions healed after resection (two cases) or curettage (two cases). One patient is considered to have a stable lesion which is not progressing.Supported in part by Speical Project Oncology, National Council for Research grant no 87.02810.44 相似文献

Aneurysmal bone cyst of the spine 总被引:2,自引:0,他引:2

The cases of twenty-two patients with an aneurysmal bone cyst of the spine above the sacrum were analyzed with regard to sex, age, site, symptoms, and radiographic findings. Four patients had extension of the lesion to the adjacent vertebra or rib, and twelve patients had neurological deficits. The primary treatment was either radiotherapy or surgery alone, or surgery and radiotherapy combined. No recurrences were found in patients who were treated with surgery alone or with surgery and radiotherapy, while three of the six patients who were treated with radiotherapy had a local recurrence, two of which were fatal. The patients with neurological deficits recovered after healing of the cyst. 相似文献

Peptide receptor radiotherapy: a new option for the management of aggressive fibromatosis on behalf of the Italian Sarcoma Group 总被引:3,自引:0,他引:3

The management of aggressive fibromatosis (AF) is problematic, and few options are available to patients unsuitable for surgery and resistant to external-beam radiation therapy (EBRT). We report on two patients with fast-growing recurrences of AF resistant to EBRT who obtained protracted clinical benefits with (90)Y-DOTATOC. (90)Y-DOTATOC should be further investigated in this setting. 相似文献

Tricalcium phosphate and hydroxyapatite ceramics in the surgery of bone tumors: preliminary results.
The authors report their preliminary experience in the use of substitutive bone compounds in order to fill the bone cavity after curettage. The material used is constituted by a biphasic compound, made up of tricalcium phosphate and hydroxyapatite. Twenty-one patients were submitted to surgery because of the presence of a benign or low-grade malignant tumor. After removing the neoplastic tissue the residual cavity was filled with: tricalcium phosphate/hydroxyapatite (5 cases); tricalcium phosphate/hydroxyapatite plus autogenous bone (8 cases); tricalcium phosphate/hydroxyapatite plus bone allografts (8 cases). A radiological evaluation obtained 12 months after treatment showed that the incorporation of the compound in granular form was nearly complete in most of the cases, while the blocks revealed partial remodelling which was more evident in the angles. Finally, bone resorption in the site of the compounds used was not observed. 相似文献
