abstract = {Effective strategies for early detection of epithelial
ovarian cancer are lacking. We evaluated whether a panel of
14 previously established circulating microRNAs could
discriminate between cases diagnosed <2 years after serum
collection and those diagnosed 2-7 years after serum
collection. miRNA sequencing data from subsequent ovarian
cancer cases were obtained as part of the ongoing
multi-cancer JanusRNA project, utilizing pre-diagnostic
serum samples from the Janus Serum Bank and linked to the
Cancer Registry of Norway for cancer outcomes.We included a
total of 80 ovarian cancer cases contributing 80 serum
samples and compared 40 serum samples from cases with
samples collected <2 years prior to diagnosis with 40 serum
samples from cases with sample collection ≥2 to 7 years.
We employed the extreme gradient boosting (XGBoost)
algorithm to train a binary classification model using
$70\%$ of the available data, while the model was tested on
the remaining $30\%$ of the dataset.The performance of the
model was evaluated using repeated holdout validation. The
previously established set of miRNAs achieved a median area
under the receiver operating characteristic curve (AUC) of
0.771 in the test sets. Four out of 14 miRNAs
(hsa-miR-200a-3p, hsa-miR-1246, hsa-miR-203a-3p,
hsa-miR-23b-3p) exhibited higher expression levels closer to
diagnosis, consistent with the previously reported
upregulation in cancer cases, with statistical significance
observed only for hsa-miR-200a-3p (beta=0.14; p=0.04).The
discrimination potential of the selected models provides
evidence of the robustness of the miRNA signature for
ovarian cancer.},
