Abstract:
Purpose To investigate epidemiology and clinical features of tumors and tumor-like lesions of the foot and ankle,as well as prognosis of malignant tumors.Methods A total of 170 patients,surgically treated for bone and soft tissue tumors of the feet and ankle between 1984 and 2009 in a tertiary referral center specializing in orthopedic oncology,were enrolled in this retrospective study.The age,gender,clinical feature,tumor types,anatomical sites,the correlation between tumor size and tumor types,and the prognosis of malignant tumor were analyzed.Results There were 91 males and 79 females,aged from 7months to 76 years (average,33.1 years).There were 51 cases of bone tumor and 119 cases of soft tissue tumor.Benign tumors commonly occurred in the second and third decades of life,with an average age of 29.54years,while most malignant tumors occurred in patients aged between 40 and 59 years,with an average age of 43.73 years.Skin lesion was a symptom implying malignance.Soft tissue tumor and benign tumor were the most common types in the foot and ankle.Giant cell tumor of the tendon sheath was the most common type among benign soft tissue tumors; subungual exostosis and enchondroma were the most common types among benign osseous tumors; while melanoma and synovial sarcoma were the most common types among malignant soft tissue lesions.Both primary and metastatic bone tumors were very rare.Forefoot was the most common site where foot and ankle tumors happened.There was no correlation between tumor size and types of soft tissue tumor,while there was a high correlation between tumor size and types of bone tumor.Among 44 patients with malignant tumor,16 patients underwent limb salvage surgery,while 28 patients underwent amputation.The mean duration of follow-up was 32.4 months.Six patients survived with no evidence of disease.The 5-year survival rate was 16.13％.Conclusion Benign and soft tissue tumors are the most common tumors in the foot and ankle.Most malignant tumors occur in patients over 40 years of age.Skin lesion is a useful symptom in diagnosing malignant tumor.Forefoot is the most common site where tumor happened.There is a high correlation between tumor size and tumor types.The prognosis of malignant tumor is very poor.
