Osteosarcomas of the hand and foot: A sarcoma‑center case series experience
Abstract
Hand and foot osteosarcoma represents ~1% of all diagnosed cases of osteosarcoma. The rarity of osteosarcoma of the hand and foot leads to frequent misdiagnosis, delayed diagnosis or incorrect treatments, which can lead to fatal consequences. Typically, salvaging the affected limb is the treatment of choice, and with the use of chemotherapy, 60-65% of patients with osteosarcoma can be treated without amputation. Due to its rarity, misdiagnosis and treatment delays are common, yet detailed reviews and analyses of such cases are limited. The present retrospective cohort study aimed to review and analyze cases of osteosarcoma located in the hand and foot. From January 2007 to January 2019, 11 patients were treated at the Masaryk Memorial Cancer Institute Sarcoma Center (Brno, Czechia), 5 cases affected the hand and 6 affected the foot. A total of 6 male patients and 5 female patients, with a mean age of 30.9±16.74 years, were diagnosed with hand or foot osteosarcoma. The mean follow-up period was 90.36±66.14 months. The mean tumor size detected during diagnosis was 4.29±1.81 cm. Osteoblastic osteosarcoma was the most common histopathological type, accounting for 4 cases (33.4%). A majority of the osteosarcomas were identified as high grade (81.8%). A total of 5 patients experienced misdiagnoses following their initial biopsy, with 2 patients initially receiving treatment outside the Masaryk Memorial Cancer Institute Sarcoma Center. The most frequently encountered misdiagnosis…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 11 participants or records.
