^aMeasured the longest diameter of the largest mass when the tumor presented as multiple nodules.

^bIndicates whether single or multiple lesions were present in the primary tumor site at diagnosis.

^cTumor recurrence observed over a follow-up period of two years.

^dValue could not be determined because an imaging study or mass excision had not been performed.

M: male, F: female.

STx: surgical resection, CTx: chemotherapy, RTx: radiation therapy, TACE: transarterial chemoembolization.
