Zusammenfassung: | Epithelial ovarian cancer (EOC) is usually diagnosed at advanced stages with highly variable clinical outcomes, even among patients with similar clinical characteristics and treatments. Host immune system plays a pivotal role in EOC pathogenesis and progression. Here, we assessed the clinical significance of 192 single nucleotide polymorphisms (SNPs) on 34 immune-system related genes in EOC patients.
Two hundred and thirty advanced EOC patients treated with platinum-based chemotherapy were included. Germ-line DNA was analyzed with Illumina GoldenGate Genotyping Assay.
Nineteen polymorphisms were significantly associated with overall survival (OS), 17 with progression free survival (PFS) and 20 with platinum-free interval (PFI). Of the 8 polymorphisms associated with all three outcomes, 7 SNPs belonged to genes involved in the TGF-β pathway. A genetic score was built considering the unfavourable genotypes (UGs) of these 7 polymorphisms (group 0–2 UGs: presence of 0, 1, or 2 UGs; group 3–4 UGs: 3 or 4 UGs; group 5–7: 5, 6, or 7 UGs). According to this score, OS decreased as the number of UGs increased (median OS: 0–2 UGs = not reached, 3–4 UGs = 44.6 and 5–7 UGs = 19.3 months, p |
