Abstract
- Purpose
This study evaluated the treatment outcomes of benign and malignant tumors of the foot to establish the treatment guidelines for foot tumors.
Materials and Methods
Eighty-three (41 male and 42 female) cases were included in the study. All patients were treated in a single institution from January 2006 to December 2022. The mean age was 43 years (range, 12–92). The mean follow-up period was 91 months (range, 5–208 months). The location of the tumor, recurrence following surgery, histologic diagnosis, overall five-year survival rate, and disease-specific five-year survival rate were evaluated. The oncologic results were analyzed at the final follow-up.
Results
Benign tumors were found in 60 cases and malignant tumors were found in 23 cases. The 41 male cases composed 25 cases of benign tumors and 16 cases of malignant tumors. The 42 female cases composed 35 cases of benign tumors and seven cases of malignant tumors. The tumor locations were 61 cases in the forefoot, five in the midfoot, and 17 in the hindfoot. Reoperation was performed in two cases due to recurrence. An un-planned excision was done in two cases, which led to secondary wide resections. The overall five-year survival rate was 65.9% (58.3% in males and 85.7% in females). The disease-specific five-year survival rate was 62.3% (62.5% in males and 66.7% in females). The oncologic outcomes of 23 malignant cases were continuous disease-free in 16 cases and died of disease in seven cases at the final follow-up.
Conclusion
Benign foot tumors were dominant (72%) in this study. The preferred location was the forefoot, with statistical significance (p<0.05). There were no statistical significant differences between males and females (p>0.05). This study provides the guidelines for treating benign and malignant foot tumors by analyzing the treatment and oncologic outcomes.
