Interferon-γ expression is an independent prognostic factor in ovarian cancer - 25/08/11
Abstract |
Background |
Epithelial ovarian cancer prognosis is improved by the presence of intratumoral CD3+ T cells, which are known to produce interferon-γ. We therefore speculated that interferon-γ expression in ovarian cancer-infiltrating T-lymphocytes might cause better prognosis.
Patients and methods |
Reverse transcriptase polymerase chain reaction was performed to measure the expression of interferon-γ and other related genes in normal ovaries (n=19) and in ovarian cancer specimens (n=99). Median follow-up of patients was 5.8 years.
Results |
Interferon-γ and CD-3 expression did not significantly differ in normal and malignant tissue. Patients with high levels of interferon-γ expression had significantly longer progression-free and overall survival. Median time to progression was 10 and 29 months for patients with low and high interferon-γ expression, respectively (P=.039). Corresponding survival times were 29 and 44 months (P < .032). Application of multivariate Cox regression analysis showed interferon-γ expression to be an independent prognostic factor for progression-free and overall survival.
Conclusion |
Elevated interferon-γ expression correlates with improved clinical outcome in patients with ovarian cancer.
