Services

Dr Bonthuys offers a comprehensive suite of radiation-oncology services, each tailored to individual needs:

• External Beam Radiotherapy (EBRT): Precision treatment using Image-Guided Radiation Therapy (IGRT) and Volumetric Modulated Arc Therapy (VMAT) to target tumours while sparing healthy tissue.

• Stereotactic Body Radiotherapy (SBRT): High-dose, focused treatments for early-stage lung, liver, and spinal lesions, often reducing the number of sessions required.

• Brachytherapy: Both low-dose and high-dose rate techniques for cervical, prostate, and gynaecological cancers, delivering radiation directly at the tumour site.

• Stereotactic Radiosurgery (SRS): Non-invasive, precision radiosurgery for brain metastases, vestibular schwannomas, and small intracranial lesions using a state-of-the-art linear accelerator.

• Palliative Radiotherapy: Symptom-relief treatments for bone pain, brain metastases, and superior vena cava syndrome, aimed at improving quality of life.

• Adaptive Radiotherapy: Daily imaging adjustments that account for anatomical changes, thus maintaining dosimetric accuracy throughout treatment.

• Radiation Planning & Dosimetry: Advanced CT/MRI simulation with fused imaging and 3D treatment-planning software to tailor dose distributions precisely.

• Oncology Risk Reduction: Strategies for mitigating late effects and secondary malignancies through dose optimization and organ-sparing approaches.

• Patient Education & Support: One-on-one sessions explaining treatment rationale, side-effect management, and follow-up care pathways.

Additional Information

Mediclinic Cape Town features a dedicated linear-accelerator bunker, a high-field MRI scanner for treatment planning, and an integrated CT simulator, which together streamline the radiotherapy workflow Mediclinic. In addition, on-site pathology and nuclear-medicine services—such as PET–CT fusion imaging—enable rapid diagnostic confirmation so treatment can commence without delay.

Dr Bonthuys contributes actively to clinical research in adaptive radiotherapy and dose-escalation protocols, and she presents at national oncology conferences. Furthermore, she publishes peer-reviewed studies on integrating immunotherapies with radiotherapy for enhanced tumour control. In addition, she mentors registrars and medical physicists, fostering excellence in the next generation of radiation-oncology specialists.

Finally, patients benefit from a multidisciplinary support team—including medical oncologists, surgical oncologists, dietitians, and social workers—which ensures that each phase of care, from diagnosis through survivorship, is coordinated seamlessly.
