Randomized trials

  1. Functional Outcomes by Ethnicity and Sex Following Tumor Resection and Endoprosthetic Reconstruction: A Secondary Analysis of the Parity Trial.RCT

    Journal of the American Academy of Orthopaedic Surgeons · Jul 01 2026 · PubMed

    Asian patients showed higher functional outcomes after endoprosthetic reconstruction for bone tumors; women demonstrated greater postoperative improvements than men.

New research

  1. Enhancing Osteosarcoma Survival Predictions: A Comparative Study of a Multicomponent-Model Machine Learning Approach Integrating SEER and NCDB Data Sets Versus Conventional Single-Data-Set Modeling.

    Journal of Bone and Joint Surgery (American) · Sep 16 2026 · PubMed

    Multicomponent machine learning approach using multiple registries improves osteosarcoma survival prediction accuracy across diverse populations versus single data-set models.

  2. A novel strategy of "Separation Surgery Combined with Vertebroplasty and Interstitial Implantation of 125I Seeds (SSVPI)" in managing thoracic metastases from lung adenocarcinoma with spinal cord compression.

    European Spine Journal · Jul 03 2026 · PubMed

    Novel separation surgery with vertebroplasty and iodine-125 seed implantation provides minimally invasive decompression and local control for thoracic metastatic spinal cord compression.

  3. Clinical Research Article Surgical Reconstruction of the Proximal Tibia in Primary Bone Tumors in Children and Adolescent Patients: A 30-Year Retrospective Study of Osteoarticular and Resurfaced Allografts.

    Journal of Pediatric Orthopaedics · Jun 26 2026 · PubMed

    Biological reconstruction of pediatric proximal tibial tumors with allografts showed 56% survival at 5 years and 48% at 10 years despite 57% complication rates.

  4. Preoperative hypoalbuminemia predicts early complications, mortality, and discharge disposition following surgical resection of spinal metastases: a nationwide study.

    European Spine Journal · Jun 08 2026 · PubMed

    Preoperative hypoalbuminemia independently predicts 30-day complications, mortality, and non-home discharge in dose-dependent fashion after spinal metastasis surgery.

  5. Tree-based and sparse logistic models for predicting one-month postoperative performance status after surgery for spinal metastases.

    European Spine Journal · May 28 2026 · PubMed

    Random Forest and sparse elastic-net models effectively predict one-month postoperative performance status after spinal metastasis surgery with good discrimination.

Recent reviews

  1. Autograft and Biologic Living Bone Reconstructions in Orthopaedic Oncology.

    Journal of the American Academy of Orthopaedic Surgeons · Feb 01 2026 · PubMed

    Biological bone autografts provide more durable long-term reconstructions than endoprosthetics but require extended healing time and carry high short-term complication rates.

  2. Management of Locally Recurrent Retroperitoneal Sarcoma in the Adult: An Updated Consensus Approach from the Transatlantic Australasian Retroperitoneal Sarcoma Working Group.

    Annals of Surgical Oncology · Nov 2022 · PubMed

    Updated consensus for recurrent retroperitoneal sarcoma emphasizes histologic type, individualized multidisciplinary treatment, and nomograms for outcome prediction.
