Example sentences for: biopsied

How can you use “biopsied” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Men with initial PSA elevations > 4 ng/ml or an abnormal DRE were biopsied and cancer cases were excluded.

  • Vallencian and colleagues biopsied 100 consecutive men with normal or non-suspicious digital rectal examinations and detected only 14 cancers, none with PSA levels below 10 ng/ml [ 29 ] . The Gann study provided the least biased estimate of sensitivity and specificity, but even these results were limited because asymptomatic cancers would not have been detected [ 24 ] . Additionally, serum was stored for about 10 years and PSA is not completely stable [ 30 31 ] .

  • Affected tissues were biopsied as appropriate for the clinical signs.

  • In the urologic literature, sensitivities ranged from 67% to 90%, specificities ranged from 28% to 59%, and positive predictive values ranged from 30% to 43% [ 9 10 11 19 20 27 28 ] . However, almost all of the published studies, including our own, are flawed by potential work-up bias because men with elevated PSA levels were significantly more likely to be biopsied.

Catalona and colleagues detected cancer in 22% of men biopsied with PSA levels between 2.6 to 4 ng/ml [ 37 ] and Lodding and colleagues detected cancers in 13% of men with PSA values between 3 to 4 ng/ml [ 39 ] . We found that lowering the cutpoint to 2 ng/ml, while greatly increasing sensitivity, led to an 80% false positive rate.
