Staging and Classification of Primary Musculoskeletal Bone and Soft Tissue Tumors Based on the 2020 WHO Update, From the Special Series on Cancer Staging.

AJR Am J Roentgenol 2021 Apr 14. Epub 2021 Apr 14.

Professor of Radiology, Mayo Clinic College of Medicine, Rochester, Minnesota and Consultant, Department of Radiology, Mayo Clinic, Phoenix, Arizona.

Staging of primary musculoskeletal bone and soft tissue tumors is most commonly performed using the AJCC and the Enneking or Musculoskeletal Tumor Society (MSTS) staging systems. Radiologic imaging is integral in achieving adequate musculoskeletal neoplastic staging by defining lesion extent and identifying regional lymph node involvement and distant metastatic disease. Additional important features in surgical planning, though not distinct components of the staging systems, include cortical involvement, joint invasion, and neurovascular encasement; these features are optimally evaluated by MRI.

Unplanned excision of soft-tissue sarcomas: current concepts for management and prognosis.

J Bone Joint Surg Am 2015 Apr;97(7):597-603

Department of Orthopaedic Surgery, Musculoskeletal Oncology Division, University of Miami Miller School of Medicine, 1400 NW 12th Avenue, Fourth floor, Room 4036, Miami, FL 33136. E-mail address for J. Pretell-Mazzini: E-mail address for M.D. Barton Jr.: E-mail address for S.A. Conway: E-mail address for H.T. Temple:

➤ Biopsy, staging, preoperative imaging and planning, as well as surgical treatment of soft-tissue sarcomas, are best carried out in specialized sarcoma centers, with the support of a multidisciplinary tumor board.➤ Tumor bed excision is recommended after most unplanned excisions, with a goal of obtaining complete tumor removal with an appropriately wide margin of resection.➤ The surgical resection area tends to be more extensive during tumor bed excision than during primary resection because of the need to resect potential areas of contamination, resulting in the need for more reconstructive procedures (flaps and skin grafts) and wider radiation fields.

Predictive value of magnetic resonance imaging in determining presence of residual disease after marginal excision of unsuspected soft tissue sarcomas of the hand.

J Hand Surg Am 2010 Sep;35(9):1479-84

Department of Surgery, Orthopaedic Surgery Service, Memorial Sloan-Kettering Cancer Center, New York, NY, USA.

Purpose: Diagnosis of a soft tissue sarcoma of the hand is at times made only in retrospect after marginal excision of a presumed benign soft tissue mass. Magnetic resonance imaging (MRI) helps determine the presence of residual disease and the extent of contamination caused by marginal excision of unsuspected soft tissue sarcomas and assists in the planning of definitive treatment with surgery and radiotherapy when required. We sought to determine the accuracy of MRI in detecting residual sarcoma after marginal excision. Read More

The biopsy.

Instr Course Lect 2004 ;53:639-44

Department of Orthopedic Surgery, University of Florida, Gainesville, Florida, USA.

The biopsy of a musculoskeletal lesion is an important event, the outcome of which guides patient management and helps determine patient prognosis. The principles of biopsy include complete radiologic staging before the biopsy, thorough prebiopsy planning including consultation with the pathologist and radiologist, determining the most appropriate method of biopsy (fine needle, core needle, open surgical biopsy), placing the biopsy tract appropriately, and making sure the biopsy tract can be removed at the time of resection, avoiding contamination of uninvolved structures, avoiding transverse incisions, preventing pathologic fracture, handling biopsy tissue appropriately, and considering referral before biopsy. The common errors of biopsy include sampling errors, postbiopsy hematomas, the use of transverse incisions, tumor implantation, and the treatment of an unsuspected sarcoma with prophylactic fixation.

[Differential diagnosis of bone and soft tissue tumors by MRI].

Orthopade 2001 Aug;30(8):528-39

Klinik für Orthopädie und Sportorthopädie, TU-München, Klinikum rechts der Isar, Ismaninger Strasse 22, 81675 München.

Musculoskeletal neoplasms are rare, and both the medical history and complaints of the patients are usually uncharacteristic and of limited information. After a clinical evaluation and biplane conventional radiography, the clinician must classify the patient as having a nonprogressive or progressive primary benign, primary malignant, or metastatic bone tumor. In the case of a probably benign, nonprogressive bone tumor, the patient has to be observed continuously or an additional biopsy should be performed. Read More

Magnetic resonance imaging of musculoskeletal soft tissue masses.

M J Siegel

Radiol Clin North Am 2001 Jul;39(4):701-20

Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA.

The role of MR imaging in the evaluation of children with large, deep, or infiltrative soft tissue masses is to characterize and determine the extent of the lesion for treatment planning. There are a small number of soft tissue tumors with MR imaging appearances characteristic enough to allow a specific diagnosis, obviating biopsy. In the remaining cases with nonspecific imaging appearances, MR imaging is used for anatomic staging, but tissue sampling is still required for determining histology and grading. Read More

The role of plain radiography, computed tomography, and magnetic resonance imaging in sarcoma evaluation.

Hematol Oncol Clin North Am 1995 Jun;9(3):571-604

Department of Radiologic Sciences, University of Texas Health Science Center at Houston, USA.

Imaging plays an important role in the diagnosis, staging, treatment planning, and post-treatment monitoring of bone and soft-tissue sarcomas. Plain radiography should be the initial imaging undertaken for patients who present with pain or a mass that may represent a musculoskeletal tumor. This is especially true of bony lesions, in which plain radiography remains the most specific noninvasive means of determining the aggressiveness of a lesion and establishing a working differential diagnosis.
