Interleukin-2 and Interferon-α for Advanced Renal Cell Carcinoma: Patient Outcomes, Sexual Dimorphism of Responses, and Multimodal Treatment Approaches over a 30-Year Period.

Introduction: Cytokine-based immunotherapy (IT) has been the mainstay of systemic treatment of advanced renal cell carcinoma (RCC) from the late 1980s until 2007. With the introduction of immune checkpoint inhibitors, a renaissance of immune oncological approaches is rapidly unfolding.

Materials And Methods: In the present study, we revisited survival outcomes, sexual dimorphism of treatment responses, and the relevance of multimodal treatment approaches over a 30-year period in 156 patients with advanced RCC treated with subcutaneous (s.
