Hospital Mário Kroeff

What Hospital Mário Kroeff does

Hospital Mário Kroeff is a philanthropic oncology hospital headquartered at Rua Magé 326 in the Penha Circular neighborhood of Rio de Janeiro, Brazil, founded in 1944 by Dr. Mário Kroeff — the same physician who established Brazil's National Cancer Service (SNC, the predecessor to INCA). The institution operates 100% through the Brazilian public health system (SUS), delivering integrated cancer care exclusively to patients referred via the SISRER regulated referral system; no private, insurance or walk-in consultations are accepted. Service portfolio spans medical specialties (Oncology, Mastology, Gynecology, Head and Neck Surgery, Urology, General Surgery, Plastic Surgery), treatment modalities (Chemotherapy, Radiotherapy, Brachytherapy, Hormonotherapy), diagnostics (Mammography, Biopsy, Ultrasonography, Colonoscopy, Radiology, Laboratory) and multidisciplinary support (Psychology, Nutrition, Physiotherapy, Speech Therapy, Social Service, Pharmacy, Dentistry). The hospital runs approximately 11,000 patient encounters per month and is staffed by ~303 employees including 170+ specialized oncology nursing professionals and credentialed medical residency programs.

The business model is a hybrid of SUS reimbursements from municipal and state health secretariats and a heavy reliance on charitable giving (PIX, monthly donations, telemarketing, the "Adote um Paciente" / Adopt a Patient campaign and corporate-sponsored events such as the annual Feijoada BGA). Governance changed in October 2024 when management transferred to Fundação Severino Sombra (FUSVE), a nearly 60-year-old philanthropic foundation operating in health and education; FUSVE's president Gustavo Oliveira do Amaral now leads strategic initiatives. The institution has received financial-restructuring support from Caixa Econômica Federal and partnerships with BGA, Brookfield, Avanço, Oncoimagem, CEASA, Legião Feminina de Combate ao Câncer, Banco Bradesco and Getnet.

The most consequential strategic initiative is the Centro de Protonterapia Mário Kroeff — Brazil's first proton therapy center, being developed in partnership with Belgian vendor IBA (Ion Beam Applications) using Proteus ONE technology, with technical-scientific oversight from INCA. The project represents an investment exceeding R$ 400 million on a 15,000 m² site in Barra da Tijuca, zona oeste of Rio de Janeiro, with first patient treatment expected by early 2030. Once operational, it will introduce precision proton radiotherapy — a modality currently unavailable in Brazil — into the SUS network.
