About

Dr. Putipun Puataweepong is a leading radiation oncologist whose research focuses on the precision treatment of intracranial tumors using advanced stereotactic radiosurgery (SRS) and hypofractionated stereotactic radiotherapy (HSRT), particularly with the CyberKnife robotic system. Her major contributions center on optimizing radiation delivery to complex, high-risk perioptic and skull base lesions. Notably, her 2015 study on hypofractionated CyberKnife radiotherapy for perioptic pituitary adenomas (32 citations) established a critical technique for treating tumors abutting the optic pathway while minimizing radiation toxicity. She further expanded this work in 2018, demonstrating the safety and efficacy of this approach for a broader range of perioptic tumors (19 citations). Dr. Puataweepong has also made significant strides in treating vestibular schwannoma, with a 2021 study (13 citations) reporting excellent long-term tumor control and hearing preservation rates using frameless CyberKnife SRS/HSRT. Her most recent work (2023) extends these principles to the challenging population of neurofibromatosis type 2 patients with bilateral vestibular schwannomas, offering hope for preserving neurological function. Through her cumulative research, Dr. Puataweepong has helped establish hypofractionated stereotactic radiotherapy as a safe, effective, and nerve-sparing alternative to single-fraction radiosurgery for critical intracranial tumors.
