| description | Objective: study of components of an insulin-like signaling pathway in kidney tissues in local and advanced clear cell renal cell carcinoma depending on the gender of patients. Materials and methods: the object of the study was conditionally intact kidney tissue and tumor and perifocal tissues obtained during the surgical treatment of 100 patients with histologically confirmed clear cell kidney cancer (local cancer (Т1-2N0М0) n=50, advanced cancer (Т3-4N0М1) n=50). Levels of the IGF-1, IGF-2, IGFBP-1 and IGFBP-2 growth factors (Mediagnost, Germany) and STH-releasing (Peninsula Laboratories International, USA) were determined by ELISA using standard test systems. The results were analyzed using Statistica 6.0 (Stat-Soft, 2001). Results: levels of IGFВР-2 and STH-releasing in conditionally intact tissues in women were 44% and 40% lower than in men, respectively. The IGFВР-2 level in perifocal tissues of women was 38% higher than in men, while STH-releasing was lower by 1.9 times. Tumor tissues of local kidney cancer in women showed significant decrease in IGF-1 by 25%, IGFВР-1 by 29% and IGFВР-2 by 2 times. Levels of IGFBP-1 and IGFBP-2 in conditionally intact tissues of women with advanced cancer were 2 and 2.7 times lower, respectively, compared to men. IGFBP-2 and STH-releasing in perifocal tissues of women were increased by 43.8% and 44.6%, respectively. In tumor tissues of women with advanced kidney cancer, levels of IGF-1 were 1.7 times higher, IGF-2 – 31% lower, IGFBP-2 – 2.8 times lower and STH-releasing – 36% lower, compared to men. Conclusions: IGFBP-2 in all studied kidney tissues in local and advanced cancer was an identically variable index characterizing gender differences in the body’s reaction to the tumor process. |
