Tumors and tumor-like lesions of the foot and ankle are relatively rare and their postoperative clinical outcome has not been well reported.
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).
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).
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.
足部和踝关节的肿瘤和肿瘤样病变相对较少，其术后临床结果尚未得到很好的报道。
本研究回顾性分析了 2008 年至 2020 年间所有接受足部和踝关节肿瘤和肿瘤样病变切除术的患者的病历。采用日本足外科学会（JSSF）评分（疼痛、功能和对线）评估术前和术后的临床结果。
本研究共分析了 117 例连续患者。骨病变 51 例（良性：45 例，中度恶性：1 例，恶性：5 例），软组织病变 66 例（良性：57 例，中度恶性：2 例，恶性：7 例）。4 例（8%）骨肿瘤和 6 例（9%）软组织肿瘤患者出现复发。8 例（67%）恶性病变患者连续无病生存，中位随访时间为 50.5 个月（范围：18 至 82 个月）。5 例（33%）恶性或中度恶性（膝下截肢：1 例，Chopart 关节离断：1 例，前足截肢：3 例）行初次手术截肢。术后 JSSF 评分显著增加（骨病变：75.9±13.7 至 91.4±14.9，p<0.001；软组织病变：84.7±14.8 至 91.9±12.5，p<0.001）。骨病变的评分改善明显高于软组织病变（p=0.003）。
足部和踝关节肿瘤和肿瘤样病变的手术治疗可获得良好的术后功能结果，骨病变的结果优于软组织病变。
