Dr Johann Riedemann – Radiation Oncologist – Brackenfell

Dr Johann Riedemann – Oncologist (Radiation Oncologist) – Brackenfell practices at Mediclinic Cape Gate, an ultramodern cancer-care facility in Cape Town’s Northern Suburbs. He earned his MBChB from the University of Stellenbosch in 2012 and completed his Fellowship in Radiation Oncology (FC Rad Onc SA) at the Colleges of Medicine in 2020. Moreover, he holds an MSc (Molecular Oncology) and pursued a PhD/post-doctoral fellowship in Molecular Oncology, thereby blending clinical expertise with cutting-edge research.

Throughout his career, Dr Riedemann has specialised in precision radiotherapy and personalised systemic therapies for young and adult patients. Consequently, he leads both paediatric and adolescent/young-adult radiation programmes, and he integrates targeted therapy and immunotherapy into comprehensive oncologic care plans. Furthermore, he contributes to multidisciplinary tumour boards and mentors junior clinicians, ensuring that every treatment aligns with the latest evidence-based protocols.

Services

• Precision Radiotherapy: including Intensity-Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) for accurate tumour targeting.

• Image-Guided Radiotherapy (IGRT): daily imaging and motion management to minimise exposure to healthy tissues.

• Stereotactic Radiosurgery (SRS) & Stereotactic Body Radiotherapy (SBRT): single-fraction or hypofractionated treatment for brain, lung, and liver lesions.

• Brachytherapy: high-dose internal radiation for gynaecologic, prostate, and skin cancers.

• Paediatric & Adolescent Radiotherapy: tailored fractionation schedules and sedation protocols to support young patients.

• Targeted Systemic Therapy: coordination of molecularly targeted agents with radiation to enhance tumour control.

• Immunotherapy Integration: combining checkpoint inhibitors and radiation for synergistic immune activation.

• Palliative Radiation: symptom-relief protocols for bone metastases, spinal cord compression, and pain management.

• Treatment Planning & Dosimetry: advanced 3D-CT and MRI planning with Monte Carlo dose calculation for optimal safety.

• Clinical Trial Participation: access to novel radiopharmaceuticals and investigational immuno-oncology agents.
