Conservative treatment with interferons (IFNs) has the advantage of preserving reproductive capacity in patients with grade 2 or 3 cervical intraepithelial neoplasia (CIN). The objective of this work was to study patients with high-grade CIN treated with intralesional IFN α-2b and to analyze the expression of Th1, Th2 and Th3 cytokines in cervical stroma. We observed that patients with a satisfactory response (60%) to treatment with IFN α-2b expressed more Th1 (IFN-γ TNF-α, IL-2) cytokines, with a significant reduction in the viral load of high-risk human papillomavirus (p = 0.0313). All patients with therapeutic failure were smokers and had higher expression of cytokines Th2 (IL-4) or Th3 (TGF-β2 and TGF-β3).
