abstract = {Pleural mesothelioma (PM) is a rare disease with dismal
outcome. Systemic treatment options include chemotherapy and
immunotherapy, but biomarkers for treatment personalization
are missing. The only FDA-approved diagnostic biomarker is
the soluble mesothelin-related protein (SMRP). Krebs von den
Lungen-6 (KL-6) is a human mucin 1 (MUC1) glycoprotein,
which has shown diagnostic and prognostic value as a
biomarker in other malignancies. The present study
investigated whether KL-6 can serve as a diagnostic and/or
prognostic biomarker in PM.Using a fully-automated
chemiluminescence enzyme immunoassay (CLEIA) for KL-6 and
SMRP, pleural effusion samples from 87 consecutive patients
with PM and 25 patients with non-malignant pleural disorders
were studied. In addition, KL-6 and SMRP levels were
determined in corresponding patient sera, and in an
independent validation cohort (n = 122). MUC1 mRNA and
protein expression, and KL-6 levels in cell line
supernatants were investigated in PM primary cell lines in
vitro.PM patients had significantly higher KL-6 levels in
pleural effusion than non-malignant controls (AUC 0.78, p <
0.0001). Among PM patients, levels were highest in those
with epithelioid or biphasic histologies. There was a strong
positive correlation between pleural effusion levels of KL-6
and SMRP (p < 0.0001). KL-6 levels in sera similarly
associated with diagnosis of PM, however, to a lesser extent
(AUC 0.71, p = 0.008). PM patients with high pleural
effusion KL-6 levels (≥303 IU/mL) had significantly better
overall survival (OS) compared to those with low KL-6 levels
(HR 0.51, p = 0.004). Congruently, high tumor cell MUC1 mRNA
expression in primary cell lines associated with prolonged
corresponding patient OS (HR 0.35, p = 0.004). These
findings were confirmed in an independent validation
cohort.This is the first study demonstrating KL-6 as a
potential novel liquid-based diagnostic and prognostic
biomarker in PM.},
