abstract = {Novel noninvasive blood-based screening tests are strongly
desirable for early detection of colorectal cancer. We aimed
to conduct a head-to-head comparison of the diagnostic
performance of 92 plasma-based tumor-associated protein
biomarkers for early detection of colorectal cancer in a
true screening setting.Among all available 35 carriers of
colorectal cancer and a representative sample of 54 men and
women free of colorectal neoplasms recruited in a cohort of
screening colonoscopy participants in 2005-2012 (N = 5,516),
the plasma levels of 92 protein biomarkers were measured.
ROC analyses were conducted to evaluate the diagnostic
performance. A multimarker algorithm was developed through
the Lasso logistic regression model and validated in an
independent validation set. The .632+ bootstrap method was
used to adjust for the potential overestimation of
diagnostic performance.Seventeen protein markers were
identified to show statistically significant differences in
plasma levels between colorectal cancer cases and controls.
The adjusted area under the ROC curves (AUC) of these 17
individual markers ranged from 0.55 to 0.70. An eight-marker
classifier was constructed that increased the adjusted AUC
to 0.77 $[95\%$ confidence interval (CI), 0.59-0.91]. When
validating this algorithm in an independent validation set,
the AUC was 0.76 $(95\%$ CI, 0.65-0.85), and sensitivities
at cutoff levels yielding $80\%$ and $90\%$ specificities
were $65\%$ $(95\%$ CI, $41-80\%)$ and $44\%$ $(95\%$ CI,
$24-72\%),$ respectively.The identified profile of protein
biomarkers could contribute to the development of a powerful
multimarker blood-based test for early detection of
colorectal cancer.},
