This study evaluated the prognostic value of soluble mesothelin-related protein (SMRP) levels in pleural effusions (PE) from patients with pleural mesothelioma (MPM).
PATIENTS AND METHODS:
SMRP level in PE was tested using an enzyme-linked immunosorbent assay (ELISA) in 109 patients with MPM at diagnosis before any treatment. The Kaplan-Meier method and the Cox regression were applied to compare overall survival probabilities across tertile categories of SMRP level.
No significant differences in Kaplan-Meier overall survival probabilities among the SMRP categories were found. A statistically non-significant trend for increased death rate ratio (RR) was computed (p=0.327) when the higher (>46.5 nM, RR=1.38) and intermediate (8.5-46.5 nM, RR=1.18) SMRP categories were compared to the lower category (<8.5 nM, RR=1.00). Cox regression modelling including a restricted cubic spline showed a moderately rising non-linear trend in death rate.
The SMRP level in PE does not appear to have prognostic significance and its detection is not recommended in routine clinical management of patients with MPM.
