BRIIL-2 is a clinical study for evaluation of efficacy and toxicity of third line treatment of pulmonary metastasis from renal cancer and melanoma with flexible bronchoscopic istillation of IL-2. Moreover, we evaluate local (BALT) and peripheral lymphocytic activation during this IL-2 administration. Up today we enrolled two patients with pulmonary metastasis from renal cancer already treated with two lines of molecular therapy, chemotherapy or systemic immunotherapy. Regarding to immunologic stimulation, lymphocytic fraction decreased from 21 to 2% in the first and from 10.5 to 6% in the second patient, indicating lymphocytic enrollment for activation, while TCD4/CD8 ratio is stable. In both patients we also observed a significant increase of HLA-DR in T lymphocytes (CD3) either in BAL or in peripheral blood. No significant major toxicities were observed after broncho-istillation, even if the dose was progressively increased. Thus IL-2 broncho-istillation could represent a valid administration modality to obtain an effective immunologic stimulation either local or systemic.
