Seminoma: Likelihood Ratios

Introduction: Seminoma is a type of Testicular Cancer.

The likelihood ratios of findings for Seminoma are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)

Poorly Diagnostic Findings
Finding	Result	+LR	-LR
[ + ] AFP		Sensitivity = 10%
Sensitivity "10-20%" for stage I, "30-50%" for disseminated disease. Study: UpToDate http://www.utdol.com/online/content/topic.do?topicKey=gucancer/7815
