ABSTRACT
INTRODUCTION: Soft tissue sarcomas (STS) are a group of rare malignant tumours that can occur at almost any anatomical location in patients of any age, which often present to health care professional working outside a recognised sarcoma service. A review of foot and ankle STSs was conducted, reporting on patient and tumour characteristics, and patient outcome following surgery performed within and outside our sarcoma service. PATIENTS AND METHODS: A retrospective review of all foot and ankle STSs managed by our sarcoma service over a 14 year period was performed. Patient demographics, tumour characteristics, management and patient outcomes including recurrence rates and survival were analysed. RESULTS: Twenty-six patients were analysed (16F:10M) with a mean age of 57.7 years (range 17-87). The mean follow-up was 6.3 years (range 1-16). Sixteen tumours involved the foot, nine the ankle, and one spanned the foot and ankle. Mean tumour size was 4.3 cm (range 0.8-15), although 61% of cases were smaller than 4 cm, and almost one third of cases smaller than 1 cm. Seven of 26 (27%) cases were diagnosed after an unplanned excision performed by non sarcoma surgeons. These patients were more likely to undergo an incomplete tumour excision (p < 0.001), suffer local recurrence (p = 0.001), and eventually undergo a secondary amputation (p = 0.034) than those patients managed exclusively by a sarcoma service. Overall, 12 (46%) patients died of their disease during follow up, equating to a five-year survival rate of 69%. CONCLUSION: Our data shows that unplanned excisions continue to be performed on foot and ankle STSs, and that these have detrimental effects on patients. Despite this, our results also show that these complex patients can be managed successfully when referred appropriately to a sarcoma service, prior to any surgical treatment. This highlights the importance of vigilance amongst all health care professionals managing any foot or ankle lumps, regardless of their size.
