The 1997 International<unk> <unk>  Consensus Classification is a tool for estimating the risk of relapse after treatment of malignant<unk> . A small study of ovarian tumors in girls reports a correlation between cystic and benign tumors, and conversely, solid and malignant tumors. Because the cystic extent of a tumor can be estimated by ultrasound, MRI, or CT scan before surgery, this permits selection of the most appropriate surgical plan to minimize risk of spillage of a malignant tumor. Access to appropriate treatment has a large effect on outcome. A 1993 study of outcomes in Scotland found that for 454 men with nonseminomatous (nongerminomatous)<unk> s diagnosed between 1975 and 1989, five-year survival increased over time and with earlier diagnosis. Adjusting for these and other factors, survival was 60% higher for men treated in a cancer unit that treated the majority of these men, though the unit treated more men with the worst prognosis. Choriocarcinoma of the testicles has the worst prognosis of all<unk> -cell cancers.
