Local recurrence and survival in soft-tissue sarcomas.

Abstract

There is a continuous interest in the literature concerning the management and survival after treatment of local recurrence in sarcomas because it is one of the most common types of recurrence. We retrospectively reviewed 93 patients treated for local recurrence from soft-tissue sarcoma. We evaluated prognostic parameters (grade, tumor size, location) and the effect of treatment on survival. Resection of all the gross tumor at first visit to our Institute for local recurrence was accomplished in 88 patients (95%). Of the 59 patients with extremity tumors, six (10%) required an amputation. At a mean follow-up of 66 months, further local recurrence was noted in 27%. The estimated 5-year survival rate was 100% for patients with grade I tumors (n = 16), 77% for grade II (n = 31), and 45% for grade III tumors (n = 46) (p = 0.0002). This value was 78% for tumors < or = 5 cm and 57% for those > 5 cm (p = 0.03). Local recurrence is resectable and limb preservation is possible in the majority of patients. The overall 5-year survival rate was 65%. Survival after treatment of local recurrence is determined mainly by the grade and secondarily by the size of the tumor as for primary sarcomas.
