Postoperative clinical and functional outcomes in patients with tumor and tumor‐like lesion of foot and ankle

Abstract

Background Tumors and tumor-like lesions of the foot and ankle are relatively rare and their postoperative clinical outcome has not been well reported. Methods This study retrospectively reviewed medical records of all patients who underwent excision of tumors and tumor-like lesions of the foot and ankle from 2008 to 2020. Preoperative and postoperative clinical outcomes were evaluated by the Japanese Society for Surgery of the Foot (JSSF) scales (pain, function, and alignment). Results A total of 117 consecutive patients were analyzed in this study. Bone lesions accounted for 51 patients (benign: 45, intermediate malignancy: 1, malignant: 5), and soft tissue lesions accounted for 66 patients (benign: 57, intermediate malignancy: 2, malignant: 7). Four patients (8%) presenting with bone tumor and six (9%) soft tissue tumors resulted in recurrence. Eight (67%) patients with malignant lesions were alive continuously disease free and followed for a median of 50.5 (range: 18 to 82) months. Amputation at the first operation was done for five cases (33%) of malignant or intermediate malignancy (below-knee amputation: 1, Chopart disarticulation: 1, forefoot amputation: 3). Postoperative JSSF scores resulted in a significant 'positive' increase (bone lesion, 75.9 ± 13.7 to 91.4 ± 14.9, p < 0.001; soft tissue lesion, 84.7 ± 14.8 to 91.9 ± 12.5, p < 0.001). The score improvement in bone lesions was significantly higher than in soft tissue lesions (p = 0.003). Conclusion The surgical management of tumors and tumor-like lesions of the foot and ankle showed good post-operative functional outcomes with bone lesions exhibiting better results when compared to soft-tissue lesions.

On the Use of New 3D Modelization, Reconstruction and Printing Techniques to Improve the Metatarsophalangeal Cancerous Lesion Management

“…A malignant bone tumor of the metatarsal phalangeal bone is a type of cancerous growth that occurs in the bones of the foot, specifically in the joint between the metatarsal and the phalangeal bone [4]. It can arise from a variety of tissues and can be classified as primary or metastatic.…”

“…Osteosarcoma is the most common type of bone cancer in general and is characterized by the production of abnormal bone tissue with stiff joint [5]. Chondrosarcoma, on the other hand, is a cancer of the cartilage, that begins in the bones and sometimes occur in the soft tissues near bones with locking the joint [4,5]. Ewing's sarcoma typically affects children and young adults with a peak incidence at 15 years of age.…”

“…Symptoms of these tumors can include increasing pain, swelling near the bone, bone injury or bone break for no clear reason, and stiffness in the affected joint [4,5].…”

Older age at surgery and postoperative leg length discrepancy are risk factors for unfavourable patient-reported outcome measures of knee tumour endoprostheses following resection for musculoskeletal tumour of the lower limb

“…1,2 Endoprosthetic reconstruction following the resection of malignant tumours arising in the limbs has been an established and widely used procedure for limb-salvaging. [3][4][5][6] A particularly common site for malignancies of the lower limbs is the knee; the oncological outcomes of patients with knee endoprosthetic reconstruction have improved. Therefore, evaluation of long-term postoperative functional outcomes around the knee is becoming increasingly important.…”
