      Prophylactic cranial irradiation in SCLC is recommended in therapy responders to primary treatment. The landmark PCI trials largely took place in the pre-MRI era. Recently, the role of brain imaging in PCI has come under increased scrutiny. We conducted this survey to gauge the patterns of brain imaging in PCI amongst radiation oncologists in Germany.

      We surveyed radiation oncology institutions in Germany via an online questionnaire sent by e-mail to member institutions in the online directory of the German Society for Radiation Oncology (DEGRO e.V.). The questions covered aspects of brain imaging in limited- and extensive-stage SCLC.

      We received a total of 39 responses. Of which 34 were completed and eligible for further evaluation. 97% and 92% of respondents recommended brain imaging prior to initial treatment in LS- and ES-SCLC, respectively with contrast-enhanced MRI being the preferred modality in 86% of cases. Ninety-one percent of respondents recommended brain imaging not older than 4 weeks prior to PCI delivery with 71% recommending commencing PCI <4 weeks after primary treatment. Of all responses, 38% followed their patients regularly with serial brain imaging following PCI with the absolute majority preferring image acquisition only in symptomatic patients. On detection of brain metastases (BMs), 59% recommended stereotactic radiosurgery (SRS) or repeat whole brain radiotherapy depending on the number of BMs.

      Patterns of brain imaging in Germany are in general consistent with the guidelines with contrast-enhanced MRI being the preferred modality for brain staging prior to primary treatment and especially after multimodality treatment and before PCI delivery.
