Is higher body mass index associated with secondary osteoarthritis in patients treated with bone cement for benign aggressive bone tumors? Long-term evaluation of 43 patients. Knee 2023; 45:178-186. [PMID: 37931365 DOI: 10.1016/j.knee.2023.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 06/07/2023] [Accepted: 10/03/2023] [Indexed: 11/08/2023]
Abstract
BACKGROUND This study was designed to investigate the secondary osteoarthritis rate in patients with benign aggressive bone tumors treated with curettage and cementing at long-term follow up. METHODS Patients diagnosed with benign aggressive bone tumor (giant cell or aneurysmal bone cyst), treated with extended curettage and cementation with polymethylmethacrylate, who had a minimum of 60 months of follow up after surgery were included in this study. After definitive diagnoses were confirmed by a histopathologist, we decided to perform standard surgical management. Osteoarthritis was staged radiologically using the Kellgren-Lawrence scoring system, and the contralateral knees of the patients were used as the control group. Based on the Kellgren-Lawrence classification system, stages 3 and 4 were accepted as the existence of osteoarthritis. Body mass index, the distance to the subchondral joint line, tumor mass volume, the location of the tumor (i.e., femur, tibia, medial condyle, or lateral condyle), age, and sex were also investigated, all of which are factors that can affect the occurrence of osteoarthritis. RESULTS Forty-three patients, 24 male (56%) and 19 female (44%), were included in the study. The mean age of the patients was 29.5 ± 10 years, and mean follow up duration was 128.7 months. Tumor localization was the distal femur in 20 patients (46.5%) and the proximal tibia in 23 patients (53.5%). The mean tumor mass volume was 77.84 cm3 and the distance to the knee joint subchondral line was 3.2 ± 2 mm. According to this scoring system, 14 patients were at stage 0, 10 patients were at stage 1, 10 patients were at stage 2, four patients were at stage 3, and five patients were at stage 4. When we compared osteoarthritis development, the affected knee had a significantly higher rate of osteoarthritis development than the contralateral knee. A univariate analysis demonstrated that age (P = 0.002) and body mass index (P = 0.045) were associated with secondary osteoarthritis. Moreover, multivariate analysis demonstrated that none of the variables were independently associated with secondary osteoarthritis. CONCLUSION Patients with contralateral osteoarthritis had bilateral knee osteoarthritis, indicating that primary osteoarthritis progressed in both knees. Seven of the 43 patients (16.2%) showed secondary osteoarthritis. Although age and body mass index were associated with secondary osteoarthritis in univariate analysis, none of the variables were independently associated with secondary osteoarthritis in the multivariate analysis.

J Cancer Epidemiol 2023; 2023:5468291. [PMID: 37153026 PMCID: PMC10162870 DOI: 10.1155/2023/5468291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 03/28/2023] [Accepted: 04/03/2023] [Indexed: 05/09/2023] Open
Abstract
Aims Giant cell tumor of the bone (GCTB) is associated with considerable morbidity. As GCTB epidemiological data for China are limited, this study is aimed at describing the disease characteristics of GCTB in China and establishing the historical context for its treatment before recent advances in treatment options. Methods The disease characteristics, treatment patterns, and local GCTB recurrence rate after primary surgery for GCTB were evaluated in this single-center, retrospective, noninterventional, observational study of patients treated for GCTB at Ji Shui Tan Hospital, Beijing, from 2009 to 2016 based on medical chart review. Patients with unmet need were defined as those whose surgical treatment was difficult or who had to undergo high-morbidity surgery. Results Among the 668 patients with a primary GCTB diagnosis, 578 (86.5%) of target lesions were in the extremities, and 89 (13.3%) were in the pelvic or axial bone. Of these, 173 (25.9%) were characterized as having an unmet need. Almost all GCTB patients received surgical treatment at both primary diagnosis (666/668 (99.7%)) and last disease recurrence (196/200 (98.0%)). Additionally, about one-third of patients received nonsurgical treatment at primary diagnosis (205/668 (30.7%)) and disease recurrence (67/200 (33.5%)), with neoadjuvant therapy being the most common treatment. The rate of high-morbidity surgery increased for recurrent disease (65/200 (32.5%)) compared with primary diagnosis (111/668 (16.6%)). The 2-year cumulative incidence of postoperative disease recurrence was 29.2%, in line with rates observed in prior studies. Conclusion As many patients with primary and recurrent disease received high-morbidity surgery, more effective treatments are needed.

Abstract
PURPOSE Giant cell tumors (GCT) of the distal radius are thought to be more aggressive than in other locations. Therefore, the aim of this study was to investigate factors associated with recurrence of GCTs in the upper extremity. METHODS We retrospectively identified 82 patients who underwent primary surgical treatment for an upper extremity GCT. Tumors were located in the radius (n = 47), humerus (n = 17), ulna (n = 9), and hand (n = 9). Treatment consisted of either wide resection or amputation or intralesional resection with or without adjuvants. A multivariable logistic regression was performed including tumor grade, type of surgery, and tumor location, from which the percentage of contribution to the model of each variable was calculated. RESULTS The recurrence rate after intralesional resection was 48%; after wide resection or amputation, it was 12%. Two patients developed a pulmonary metastasis (2.4%). In multivariable analysis, intralesional resection was independently associated with recurrence. Intralesional resection had a 77% contribution to predict recurrence and the distal radius location had a 16% contribution in the predictive model. CONCLUSIONS As expected, intralesional resection was the strongest independent predictor of recurrence after surgical treatment for GCT. The distal radius location contributed to the prediction of giant cell tumor recurrence to a lesser extent. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
The malignant transformation of conventional giant cell tumor of bone (GCTOB) is rare and usually occurs with irradiation. Here we report two neglected cases of conventional GCTOB with spontaneous malignant transformation at 11 and 16 years after initial diagnosis. In the former case, the patient refused to receive any treatment following the incisional biopsy, and in the latter, the first recurrence that occurred 5 years after initial treatment, was neglected. Although rare, the occurrence of sarcomatous changes in these cases indicates that secondary malignant transformation may be part of the natural course of this tumor. In addition, in both cases, immunohistochemistry showed diffuse and strong p53 expression in the malignant tumor but not in the primary lesion. It suggests that p53 overexpression may play a key role in the malignant transformation of GCTOB and that investigating for p53 expression in recurred lesions may help in predicting cases of giant cell tumor, prone to malignant transformation.

Abstract
Introduction: Giant cell tumors are rarely observed in the thoracic vertebrae. They appear between the ages of 20 and 50, more often in women. The purpose of this case report is to make known the clinical characteristics, the presentation and the treatment used to solve this pathology.Case presentation: 37-year-old female patient who presented a clinical picture of seven days of dyspnea, cough with white expectoration, high temperature, paraparesis, loss of control in the sphincters and weight loss. High-resolution computed tomography of the thorax showed a right paraspinal mass located in posterior mediastinum at T8-T9 level. Surgical excision of the tumor was decided by right posterolateral thoracotomy at the seventh intercostal space and free surgical margins. The histopathology report described giant cell tumor grade II. The patient did not require chemotherapy and had a satisfactory evolution.Discussion: This case has a non-specific presentation, as it shows evidence of pain, tumor and functional impotence of the involved region. Surgery is the best treatment and consists of tumor excision, leaving wide margins to prevent recurrences.Conclusions: Giant cell tumors involving the lungs and thoracic vertebrae are underdiagnosed due to their nonspecific symptoms and the limited literature currently available.

Abstract
Background Data on long-term prognosis of metastatic GCT (mGCT) is scant. The frequency of spontaneous regressions (SRs) is unknown. We aimed to estimate the prognosis of mGCT. Methods We searched electronic scientific literature databases and generic Internet from January 1980 to August 2017. After identifying eligible studies we performed descriptive analyses and meta-analyses to estimate overall survival (OS), disease specific survival (DSS) and frequency of SRs in the years before the widespread use of denosumab. We performed pre-specified subgroup analyses of studies published before and after 2000 and of those with more and less than 10 years of follow-up. Results After retrieving and combining data from 26 relevant retrospective case-series totaling 242 patients with a median follow-up of 6.9 years, the estimated pooled OS was 86.9% (95% CI 78.0-94.2). Pooled DSS was 88.0% (95% CI 79.7-94.7). SRs were observed in 4.5% of patients. In the subgroup of studies published after 2000 mGCT was the only cause of death of affected subjects. In case-series with a follow-up longer than 10 years pooled DSS was 69.7% (95% CI 25.5-99.8). Conclusions To our knowledge this is the first study to derive estimated pooled OS and DSS of mGCT based on a large dataset. SRs were not exceptional phenomena. In a long run the disease could impact in a significant way on the life expectancy of affected subjects.

Abstract
Background Quantifying the incidence of giant cell tumor (GCT) of bone is challenging because it is a rare, histologically benign bone tumor for which population-level statistics are unavailable in most countries. We estimated the 2017 incidence of GCT in China using a direct (registry-based) approach with available population-based data. Materials and Methods The most recent age- and sex-specific incidence rates of GCT recorded in the Bone Tumor Registry in Japan (2015) were applied to 2017 age- and sex-matched populations projected by the United Nations for China in order to estimate 2017 incidence. An adjustment factor calculated using registry data suggesting that GCT may represent a greater proportion of bone tumors in China than in Japan (Guo, 1999) was applied to provide secondary estimates. Results Annual GCT incidence was estimated to be 1.49 per million population or 2094 new cases in China for 2017. A comparison of this estimated incidence with Japan (1.25 per million) and the United States (1.38 per million) indicates that the incidence is somewhat higher in China using identical methods. Secondary estimates suggest that GCT incidence in China may be as high as 2.57 per million or 3625 new cases in 2017. The corresponding 3-year limited-duration prevalence of GCT in China using a registry-based approach and general age-specific mortality is 6276 (secondary estimate: 10,876). Conclusions Leveraging unique population-based registry data, we estimated that GCT is a rare disease in the Chinese population with an incidence ranging between 1.49 and 2.57 cases per million persons per year. Possible differences in diagnostic classification of GCT, urban-rural demographics, and the younger demographic distribution of the Chinese population may underlie observations that GCT, a condition that primarily affects young individuals (20-40 years of age), accounts for a higher proportion of skeletal tumors in China than in other regions.

Orthop Traumatol Surg Res 2017; 103:1075-1079.

Abstract
INTRODUCTION Giant cell tumors (GCTs) make up 15 to 20% of bone-related tumors in adults. They are often found around the knee in the metaphysis and epiphysis area, contacting the joint cartilage. The aims of our study were to evaluate the presence of early knee osteoarthritis (OA) in patients with GCTs in the knee area treated by curettage-cement packing, and to evaluate whether replacing subchondral bone with acrylic cement has an effect on the functional outcomes and quality of life. MATERIAL AND METHODS This was a retrospective study of all patients operated between 2000 and 2010 by the same specialized surgical team. Functional outcomes and quality of life were evaluated in each patient using the Knee Injury and Osteoarthritis Outcome (KOOS), the Musculoskeletal Tumor Society Score (MSTS) and the Short Form-36 (SF-36). The presence of OA was evaluated in a full radiological work-up comparing the operated knee with the healthy contralateral knee. Knee OA was defined as grade 3 or grade 4 radiographic findings based on the Kellgren and Lawrence classification, and a significant difference between the operated and contralateral knee. RESULTS Nineteen patients were included in this study. The average follow-up was 120 months (range 60-180). Four patients (21%) had radiographic KL-3 and one patient (5%) had KL-4. Eight patients (42%) had recurrence of the GCT. The distance between the tumor and cartilage, and the area of the subchondral bone invaded by the tumor appeared to contribute to OA progression. DISCUSSION Resection of GCTs around the knee by curettage-cement packing did not have an effect on development of OA. In the four patients who developed knee OA, the tumor was located less than 3mm from the joint cartilage and took up more than 90% of the epiphysis. Based on these observations, there seems to be a strong correlation between the development of knee OA and the small quantity of subchondral bone left after curettage. The functional outcomes and quality of life were similar no matter the knee OA grade in patients. Replacing subchondral bone by cement had no effect on quality of life in this study. LEVEL OF EVIDENCE IV (retrospective study).

Abstract
Steroids are known to inhibit osteogenic differentiation and decrease bone formation in mesenchymal stem cells (MSCs), while concomitantly inducing steroid-induced avascular necrosis of the femoral head (SANFH). The aim of the present study was to evaluate the function of MSCs on differentiation in SANFH and investigate the pathobiological mechanisms underlying SANFH in a rabbit model. MSCs in the control, trauma-induced ANFH (TANFH) and SANFH groups were incubated with low-glucose complete Dulbeccos modified Eagles medium containing 10% fetal bovine serum. A number of adipocytes in the MSCs were stained with Sudan III and counted using a light microscope. The mRNA and protein expression levels of the adipose-specific 422 (AP2), peroxisome proliferator-activated receptor-γ (PPARγ), RUNX2, collagen type I (Col I) and miR-103 in the MSCs were determined using quantitative polymerase chain reaction and western blot analysis, respectively. In addition, the activities of osteocalcin (OC), alkaline phosphatase (ALP) and triglyceride (TG) in MSCs were analyzed using radioimmunoassay and determination kits. In the MSCs of the SANFH group, the mRNA and protein expression levels of AP2 and PPARγ were increased, while those of RUNX2 and Col I were reduced. Furthermore, the levels of OC and ALP activity in the MSCs of the SANFH group were decreased, and the activity of TG in the MSCs of the SANFH group was increased. In addition, the expression of miR-103 in the MSCs of the SANFH group was elevated. Following routine culture of the MSCs for 3 weeks, the number of adipocytes among the MSC population of the SANFH group was increased. Therefore, the results of the present study suggest that the osteogenic differentiation of MSCs in the SANFH was mitigated, while fat differentiation was promoted, which provides a novel explanation for the pathological changes associated with SANFH.

Abstract
Giant cell tumor of bone (GCTB) is a primary benign bone tumor with a locally aggressive character. Definitive descriptions of the site of origin for this type of tumor are not available. The aim of the present study was to evaluate the site of origin of GCTB of long bones with regards to epiphyseal lines by means of radiographic examination. For that purpose, plain X-ray scans of 71 GCTBs arising in long bones were retrospectively reviewed. The tumor locations were the distal femur in 31 cases, proximal femur in 11 cases, proximal tibia in 13 cases, distal radius in 6 cases, proximal humerus in 5 cases and proximal fibula in 5 cases. The vertical center (VC) of the tumor was determined with X-ray anteroposterior view, and the correlation between the VC and the epiphyseal line, and between the distance from the epiphyseal line to the VC and tumor area or volume were analyzed using a regression model equation based on scatter plot diagrams. The VC of the tumor was located in the metaphyseal region in 57 cases, in the epiphyseal line in 11 cases and in the epiphyseal region in 3 cases. In cases of GCTB located in the distal femur or proximal tibia, significant correlations between the distance from the VC to the epiphyseal line and tumor area or volume were identified. The site of origin of GCTB was estimated to be located in the metaphyseal region. GCTB often occurs in mature patients, which renders it challenging to estimate the true site of origin of this lesion, since the metaphyseal line has disappeared in mature patients. The results of the present study suggest that GCTB possibly originates in the metaphyseal region.
