Dr Wong Ru Xin graduated from the National University of Singapore on the Dean’s list in 2009 and started residency training shortly after. Soon after, she became a Fellow of the Royal College of Radiologist (clinical oncology). Dr Wong worked at the National Cancer Centre of Singapore as a radiation oncologist for more than 10 years before leaving for private practice. As part of her training in proton therapy, she spent time at St. Jude Children’s Research Hospital and observed at Provision Cares Proton Centre, and Kobe Proton Centre. Her practice includes radiation therapy technology, and the treatment of breast, head and neck, paediatric, brain, skin cancer, and sarcoma. Dr Wong is skilled in the use of 3D, IGRT, VMAT, SBRT and Proton Beam Therapy in treating cancer. She has attended relevant courses like Winter School in Particle Therapy, ESTRO Particle Therapy, ESTRO Radiobiology and Physics, and ESTRO Stereotactic Radiosurgery.

Dr Wong was the principal investigator in a few clinical trials and studies while in public institutions. She also taught medical students and residents and continues to teach oncology nurses. She has organised various webinars and symposiums in the past for local and international faculty. She has published local and regional papers on cancer prognostication, outcomes, and using novel techniques. Dr Wong concluded a clinical trial using hypo-fractionated radiotherapy in sarcomas. She also received grants to implement open-faced masks and silicon grip rings for patient comfort, electronic patient-reported outcomes, and study repeat MRI for adaptive radiotherapy in intracranial malignancies. While at National Cancer Centre, she implemented new clinical technologies like pulsed low-dose rate radiotherapy and collaborated with her colleagues to implement paediatric interstitial brachytherapy for rhabdomyosarcoma.
She hopes to bring proton and advanced photon radiotherapy to Singapore and the region. Dr Wong is leveraging SAM network on the FLASH therapy consortium to investigate new technologies. She continues to serve the public as a visiting consultant at NCC Singapore and KK Hospital.
