20.500.12556/DiRROS-29961 Serum calretinin and genetic variability as a prognostic and predictive factor in malignant mesothelioma : Calretinin is a promising diagnostic biomarker for malignant mesothelioma (MM), but less is known about its prognostic role. Our aim was to evaluate the association between serum calretinin concentration or genetic factors and the survival or outcome of cisplatin-based chemotherapy in MM. Our study included 265 MM patients. Serum calretinin concentration was determined using ELISA. Patients were genotyped for seven polymorphisms in CALB2, E2F2, MIR335, NRF1, and SEPTIN7 using competitive allele-specific PCR. Nonparametric tests, logistic regression, and survival analysis were used for statistical analysis. Higher serum calretinin concentration was associated with shorter progression-free (PFS) (HR = 1.18 (1.02–1.37), p = 0.023) and overall survival (OS) (HR = 1.20 (1.03–1.41), p = 0.023), but the association was not significant after adjusting for clinical factors (HR = 1.05 (0.85–1.31), p = 0.653 and HR = 1.06 (0.84–1.34), p = 0.613, respectively). SEPTIN7 rs3801339 and MIR335 rs3807348 were associated with survival even after adjustment (HR = 1.76 (1.17–2.64), p = 0.007 and HR = 0.65 (0.45–0.95), p = 0.028, respectively). Calretinin concentration was higher in patients who progressed after treatment with cisplatin-based chemotherapy (1.68 vs. 0.45 ng/mL, p = 0.001). Calretinin concentration above 0.89 ng/mL was associated with shorter PFS and OS from the start of chemotherapy (HR = 1.88 (1.28–2.77), p = 0.001 and HR = 1.91 (1.22–2.97), p = 0.004, respectively), even after adjusting for clinical factors (p < 0.05). MIR335 rs3807348 was associated with a better response to chemotherapy (OR = 2.69 (1.17–6.18), p = 0.020). We showed that serum calretinin is associated with survival and chemotherapy treatment outcomes in MM and could serve as a predictive biomarker. malignant mesothelioma calretinin biomarkers polymorphism maligni mezoteliom kalretinin biološki označevalci polimorfizem true false true Angleški jezik Slovenski jezik Neznano 2026-06-10 12:36:29 2026-06-10 12:36:29 2026-06-11 03:47:35 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 28. 12. 2023; str. 190-1-190-17 no. 1 Vol. 25 Jan. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.2 1422-0067 10.3390/ijms25010190 178934019 RAZ_Zupanc_Cita_2024.pdf RAZ_Zupanc_Cita_2024.pdf 1 5AD94FD83A417A319D298F6BC8AA39D0 71637f80d2e3665fca6a4e423b9ee4e094b9241a30c1d9b3954fa7e0f65dc0df 61f994e9-64b8-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45127 https://www.mdpi.com/1422-0067/25/1/190 0 3f56c894-64b8-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45126 Univerzitetni klinični center Ljubljana 0 0 0
