Prognosis:
Benign GCTs show excellent prognosis even when recurrence is present [11,55]. With excision using wide margins, recurrence has been reported in 2-8% of cases [55]. When incompletely excised, the recurrence rates increase to 21% to 50% [29]. After removal of a GCT, some authors suggest that a long term follow up of 10 years should be performed because distant recurrences have been documented [56], but there is no clear consensus or standards on this matter [14]. Malignant GCTs have a worse prognosis, with 74% and 65% survival rates at 5 years and 10 years, respectively. Malignant GCTs show a recurrence rate of 32% to 41% and metastasis rate of 11 to 62% between 3 to 37 months after diagnosis [11]. Those with distant metastases at diagnosis have 0% survival at 5 years compared to 81% in those without metastases [11].
