^aInterpreted as positive (+) when at least 10 out of 50 tumor cells (20%) showed separate green and orange signals using TFE3 break-apart probes.

^bInterpreted as positive (+) when the YAP1-TFE3 fusion transcript was observed via RT-PCR.

^cInterpreted as positive (+) when at least 10 out of 50 tumor cells (20%) showed separate green and orange signals using CAMTA1 break-apart probes.

^dInterpreted as positive (+) when the WWTR1-CAMTA1 fusion transcript was observed via RT-PCR.

^eValue could not be determined because RNA extraction was failed.
