57 Treatment and survival in the Netherlands size (>5cm) was then the strongest predictor of poorer survival (p<0.05). However, when tumor sizes were smaller than 5cm, only the patient’s gender remained a critical factor significantly associated with survival; female patients had a worse prognosis (p<0.05).
