A 1982 Musculoskeletal Tumor Society questionnaire study across 16 centers and 329 patients with malignant primary bone and soft-tissue tumors. It asks: how often does biopsy produce diagnostic errors or wound complications, and does it matter where the biopsy is done? The findings established the foundational rule that biopsy must be performed by — or after referral to — the surgeon who will perform definitive resection.
Every orthopedic oncology rotation begins with a version of this rule: do not biopsy a tumor you cannot resect. This paper is where that rule comes from.
When you see a patient referred with an already-biopsied suspicious bone or soft-tissue mass, check the incision immediately. A transverse incision, a poorly placed drain site, or a contaminated tissue plane can force a wider resection or convert a limb-salvage candidate to an amputation. The paper shows this happened in 4.5% of cases.
The prescriptive take-away is straightforward: if your institution cannot stage and resect the tumor, send the patient before touching it. A biopsy done at a non-treating center carried more than 3x the diagnostic error rate and more than 4x the wound complication rate in this series.
The authors also flag that their numbers are likely an underestimate — patients initially misdiagnosed as malignant (who turned out benign) were excluded, meaning the true complication burden of poorly planned biopsies is even higher than reported.
