Stereotactic radiotherapy (SRT)/Stereotactic body radiotherapy (SBRT) constitutes extensively employed therapeutic modalities for various cancer types in our country, offering precise and conformal delivery of high radiation doses. This survey aims to analyze the current status of SRT/SBRT in our country.
METHODS
A total of 34 questions were asked by an online survey through Google Forms (SurveyMonkey) in October
2021. This nationwide survey focused on the demographic information of participants, SRT application
techniques, treatment planning, and the utilization of SRT in clinical practice.
RESULTS
The survey was completed by a total of 106 respondents. A predominant number of participants belonged
to the 40-50 age group, with <10 years of experience. Linear accelerators (92%) were the most
common devices used for SRT, followed by CyberKnife (27%), Gamma Knife (5%), and Magnetic resonance
imaging-Linac (3%). Combined kilovolt/megavolt portal imaging with cone-beam computed
tomography (CBCT) was the most commonly used imaging verification method (58%). Treatments
typically began within 2-7 days (76%) after simulation. The number of patients treated with SRT/SBRT
over the past year varied in a wide range, with a median of 50 (range: 0-1000) patients. SRT/SBRT was
applied in many cancer types including mostly brain (98%), lung (89%), bone (89%), adrenal (64%),
liver (47%), prostate (42%), head and neck (41%), pancreas (35%), and other tumors (3%).
CONCLUSION
SRT/SBRT applications in our country vary in terms of number, experience, and treated tumor groups.
These results are crucial for understanding the current status of SRT, treatment indications, challenges,
and diversity in application approaches in our country.
