The SYT/SSX1 fusion gene is associated with more aggressive tumor growth and poor outcome.     ///    SYT/SSX1 translocations are seen in nearly three times as many synovial sarcomas as SYT/SSX2 translocations.     ///    HER-2/neu expression by immunohistochemistry in synovial sarcomas was restricted to tumors with the SYT/SSX1 translocations.     ///    "EGFR and HER-2/neu are expressed in the majority of patients with SYT/SSX1 synovial sarcomas, albeit at low levels. "    ///    "Although the SYT/SSX2 fusion is usually associated with the monophasic disease pattern, the SYT/SSX1 fusion is present in tumors with biphasic or monophasic patterns. "
