Abstract
Objective: The study aimed to explore a new approach for the treatment of osteosarcoma through combining biomaterials with next-generation small molecule–based targeted therapy. Methods: The model of osteosarcoma was established by 4-hydroxyaminoquinoline 1-oxide (4-HAQO) in mice while the collagen-thermosensitive hydrogel–calcium phosphate (CTC) biocomposites were prepared, and the small molecule inhibitors were virtually screened and synthesized. Then, for the osteosarcoma cell line, MG-63 cells were used to validate our bioinformatic findings in vitro, and the mouse osteosarcoma models were treated by combing CTC composites and small-molecule inhibitors after debridement. Results: Five compounds, namely, ZINC150338698, ZINC14768621, ZINC4217203, ZINC169291448, and ZINC85537017, were found in the ZINK database. Finally, ZINC150338698 was selected for chemical synthesis and experimental verification. The results of the MTT assay and Hoechst staining showed that the small-molecule inhibitor ZINC150338698 could significantly induce MG-63 cell death. Furthermore, CTC composites and ZINC150338698 could repair the bone defects well after the debridement of osteosarcoma. In addition, the biomaterials and small-molecule inhibitors have good biocompatibility and biosafety. Conclusion: Our findings not only offer systems biology approach-based drug target identification but also provide new clues for developing novel treatment methods for future osteosarcoma research.

Proximal femur versus acetabular extra-articular resection of the hip joint for primary malignant bone tumors: a retrospective comparative review of 33 cases. World J Surg Oncol 2022; 20:168. [PMID: 35643461 PMCID: PMC9145149 DOI: 10.1186/s12957-022-02642-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Accepted: 04/01/2022] [Indexed: 11/18/2022] Open
Abstract
Introduction Extra-articular resection (EAR) of the hip joint is prone to significant complications and morbidity. Thus, this study evaluates the cumulative incidences and main reasons of reoperation following EAR of primary malignant bone tumors (PMBT) of the hip to determine whether the outcomes are different between EAR of the pelvis and that of the proximal femur. Patients and methods Thirty-three patients presented with a PMBT of the proximal femur or pelvis were included in this study. Among all PMBTs, 58% originated from the pelvis and 42% were from the proximal femur. Twenty patients had chondrosarcomas (61%), 10 had osteosarcomas (30%), and 3 had sarcomas of another histological subtype (9%). Results The mean follow-up was of 76 months (range: 24–220 months). The cumulative probabilities of revision for any reason were 52% (95% confidence interval [CI] 30–70%) 5 years after surgery. The 5-year cumulative probabilities of revision were 13% (95% CI 4–27%), 24% (95% CI 10–42%), and 34% (95% CI 14–56%) for mechanical, infectious, and tumoral reasons, respectively. The 5-year cumulative probabilities of revision for any reason were 78% (95% CI 37–94%) and 14% (95% CI 2–38%) for the pelvis and proximal femur, respectively (p = 0.004). Posterior column preservation was significantly associated with more mechanical complications even after adjusting for the resection site (p = 0.043). Conclusion Half of patients undergoing EAR of the hip joint for PMBT of the proximal femur or acetabulum will require another operation. EAR of the pelvis is associated with significantly worse outcome than EAR of the proximal femur.

Comparative efficacy of intraoperative extracorporeal irradiated and alcohol-inactivated autograft reimplantation for the management of osteosarcomas-a multicentre retrospective study. World J Surg Oncol 2021; 19:157. [PMID: 34039361 PMCID: PMC8157677 DOI: 10.1186/s12957-021-02271-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 05/19/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Biologic bone reconstruction in limb salvage surgery for the treatment of malignant bone tumours has always been controversial. The various inactivation methods, their convenience and stability, the curative effects elicited and associated costs all need to be considered. This study aimed to compare the clinical efficacy of intraoperative extracorporeal irradiated reimplantation with alcohol-inactivated autograft reimplantation for limb salvage surgery in patients with osteosarcoma. METHODS We retrospectively analysed 28 patients with osteosarcoma, 14 patients treated with intraoperative cobalt 60 irradiation and reimplantation (group A), and 14 patients treated by alcohol-inactivated autograft reimplantation (group B). The postoperative complications and clinical efficacy of each treatment method were compared by statistical analysis. RESULTS The local recurrence rate was 14.3% in each group. Complete bony union was achieved in 64.3% of patients in group A and 71.4% of patients in group B. The overall 5-year survival rate was 71.4% in group A and 78.6% in group B. The mean Musculoskeletal Tumor Society (MSTS) score was 25.33 ± 4.72 (range 15-30) in group A and 24.00 ± 5.85 (range 15-30) in group B, and the mean International Society of Limb Salvage (ISOLS) score was 25.79 ± 5.13 (range 20-36) in group A and 26.14 ± 5.33 (range 20-30) in group B. P < 0.05 was considered to indicate a significant difference. The results showed that the long-term clinical efficacy did not differ significantly between the two methods. CONCLUSIONS In limb salvage surgery for osteosarcoma, intraoperative extracorporeal irradiation and alcohol-inactivated autograft reimplantation yielded equivalent outcomes. The alcohol-inactivated method may be a much more convenient and inexpensive way to reconstruct bone defects. Additional studies as well as more case studies are needed to fully evaluate the clinical efficacy and safety of this treatment method.
