Fiducial Marker Practice in Prostate Radiotherapy in Turkey.

Objective: During prostate radiotherapy (RT), localization strategies of the prostate gland are essential. Fiducial markers (FMs) are one of the various methods for prostate localization. FMs for prostate RT have been in use for several years. This study aimed to evaluate the current trends in FM practices used in the treatment of prostate cancer in Turkey. Materials and Methods: An electronic survey containing 15 questions was developed on SurveyMonkey.net and sent to the email addresses of 600 radiation oncologists (ROs) via the Turkish Society for Radiation Oncology. Then, the data were collected and analyzed. Results: A total of 33 ROs completed the survey. Upon analysis, results revealed that the mean FM experience duration was 6.6 years (range: 1-18 years). FM replacement was mainly done transrectally (90%) by urologists (67.7%). Antibiotic prophylaxis and anticoagulant cessation were often practiced. At least three gold FMs were inserted in most of the cases. Conclusion: Many centers use FMs for prostate RT in Turkey. There are some differences in FM usage. Standardization of the practice could help to investigate and improve FM utilization in prostate RT. [ABSTRACT FROM AUTHOR]
