Orthopedic Oncology: Diagnosis and Treatment of Bone Cancers provides a systematic exploration of musculoskeletal tumors, establishing a critical foundation for the clinical evaluation and diagnostic workup essential for accurate patient management. The discipline requires a methodical approach, beginning with a meticulous patient history and physical examination that identifies key indicators of neoplastic disease, such as nocturnal pain or a rapidly enlarging mass. This initial assessment directly informs the subsequent diagnostic pathway, guiding the selection of appropriate imaging studies and the strategic planning of a biopsy. The field is broadly categorized into benign bone tumors and malignant bone tumors, each possessing distinct biological behaviors, clinical presentations, and management imperatives. Benign lesions, such as osteochondromas or enchondromas, often require simple observation or straightforward surgical intervention, while malignant sarcomas, like osteosarcoma or Ewing sarcoma, demand a complex, multi-modal treatment strategy. A parallel domain involves soft tissue sarcomas with orthopedic implications, which present unique diagnostic challenges due to their deep-seated locations and necessitate specialized surgical techniques for wide-margin resection and functional reconstruction.

The principles of management are further refined when considering the unique context of pediatric bone tumors, where the preservation of growth plates and the management of future limb-length discrepancies become paramount concerns in addition to oncologic control. Across all age groups and tumor types, imaging in orthopedic oncology serves as the cornerstone for diagnosis, local staging, and treatment planning. Modalities such as magnetic resonance imaging provide exquisite detail on the relationship of a tumor to neurovascular structures and the extent of marrow involvement, while computed tomography is superior for characterizing bone destruction and screening for pulmonary metastases. The information gleaned from advanced imaging directly informs the execution of surgical techniques in orthopedic oncology, which range from intralesional curettage for benign lesions to wide-margin limb-salvage resections and complex reconstructions using endo-prostheses or allografts for malignancies. The surgical objective is always to achieve complete oncologic resection while preserving as much function as possible, a balance that requires significant expertise and careful pre-operative planning.
