BACKGROUND: Previous studies have reported a poor outcome for synovial sarcoma patients whose tumours relapse. METHODS: This study analysed 44 relapsing cases in a series of 118 consecutive patients <21yr of age with non-metastatic synovial sarcoma prospectively enrolled in Italian paediatric protocols between 1979 and 2006. In an effort to identify a possible risk-adapted stratification enabling a better planning of second-line treatment, the relapsing patients' outcome was analysed vis-à-vis their clinical picture at onset, first-line treatments, clinical findings at the time of first relapse and second-line treatment modalities. RESULTS: The first event was a local recurrence in only 15 cases, and metastatic in 29 (associated with local relapse too in 7 cases). The time to relapse ranged from 4 to 108months (median 20months). Overall survival was 29.7% and 21.0% five and ten years after relapsing, respectively. The variables influencing survival were the timing and type of relapse (combined) and the chances of a secondary remission, which correlated strongly with the feasibility of complete surgery. CONCLUSIONS: Our study confirmed a largely unsatisfactory prognosis after recurrences in children and adolescents with synovial sarcoma: the chances of survival can be estimated on the basis of several variables for the purposes of planning risk-adapted salvage protocols. An aggressive surgical approach should be recommended. New effective systemic agents are warranted, and experimental therapies can be offered to patients with little chance of salvage.

Abstract

BACKGROUND: Previous studies have reported a poor outcome for synovial sarcoma patients whose tumours relapse. METHODS: This study analysed 44 relapsing cases in a series of 118 consecutive patients <21yr of age with non-metastatic synovial sarcoma prospectively enrolled in Italian paediatric protocols between 1979 and 2006. In an effort to identify a possible risk-adapted stratification enabling a better planning of second-line treatment, the relapsing patients' outcome was analysed vis-à-vis their clinical picture at onset, first-line treatments, clinical findings at the time of first relapse and second-line treatment modalities. RESULTS: The first event was a local recurrence in only 15 cases, and metastatic in 29 (associated with local relapse too in 7 cases). The time to relapse ranged from 4 to 108months (median 20months). Overall survival was 29.7% and 21.0% five and ten years after relapsing, respectively. The variables influencing survival were the timing and type of relapse (combined) and the chances of a secondary remission, which correlated strongly with the feasibility of complete surgery. CONCLUSIONS: Our study confirmed a largely unsatisfactory prognosis after recurrences in children and adolescents with synovial sarcoma: the chances of survival can be estimated on the basis of several variables for the purposes of planning risk-adapted salvage protocols. An aggressive surgical approach should be recommended. New effective systemic agents are warranted, and experimental therapies can be offered to patients with little chance of salvage.
