Seventy-six patients were studied, diagnosed with MPN from 1984 to 2012 with a median follow up period of 55 months. IL-8 and OPG immunostaining was performed on paraffin-embedded sections of formalin fixed BM biopsies, carried out at the time of diagnosis, using the two-step peroxidase conjugated polymer technique. Grade of positivity and intensity of IL-8 and OPG expression was scored according to a 0 to 3 scale. Statistical analysis was performed conventionally, using the SPSS version 22.0 package, and p values <0.05 were considered significant. High intensity of IL-8 expression in megakaryocytes correlated, in the whole cohort, with neutrophilia (p=0.005) and high haemoglobin (p=0.001). High intensity of OPG expression in megakaryocytes correlated high haemoglobin (p=0.017) and a favorable karyotype (p=0.01). Most importantly, low OPG intensity in megakaryocytes correlated with poor survival (p=0.026) in the whole patient series. In conclusion, our most important finding is that high intensity of OPG expression in megakaryocytes correlated with increased survival and a favorable karyotype in patients with MPN, a finding that has not been reported yet.</p>", "author": [ { "family": "Diana T, Dimitrios M, Eleni-Andrianna T, Tatiana T, Theodoros I, Maria D, Aspasia K, Kallirroi S, Panagiota N, Efstratios P, Maria KA, Maria K, Panayiotis P, Penelope K, Marie-Christine K" } ], "page": "432-439", "volume": "6", "type": "article-journal", "issue": "12", "id": "2536548" }
