Abstract:

Background and Purpose: Prophylactic Cranial Irradiation (PCI) is considered as standard of care for patients with Limited Stage Small-Cell Lung Cancer (LS-SCLC). Several clinical studies demonstrated a narrow survival benefit for PCI. However, all of them were completed before the wide introduction of Magnetic Resonance Imaging (MRI) for diagnosis and follow up of brain metastases. Therefore, a requirement for PCI is uncertain when brain involvement can be excluded by MRI-scan. We conducted an international survey attempting to gauge the attitude of oncology professionals to possible replacement of PCI by close MRI-based surveillance in the management of LS-SCLC.
Materials and Methods: A questionnaire was designed to survey the attitudes of medical and radiation oncologists toward PCI in LS-SCLC. An invitation was sent to 638 medical and radiation oncologists by e-mail obtained from professional society directories. The e-mail contained a link to an online platform where the survey could be accessed.
Result: Responses were received from 61 oncologists employed by 47 centers, located in 15 countries. Omission of PCI in favor of MRI-based surveillance was supported by 36.1% of respondents. This support was significantly higher among medical as opposed to radiation oncologists (p=0.022). The majority of responders considered stereotactic radiosurgery as the preferred salvage therapy for brain metastases in both PCI-naive and PCI-exposed patients.
Conclusion: A substantial proportion of cancer specialists can support omission of PCI in favor of regular MRI-based follow up for patients with LS-SCLC. A randomized controlled trial is highly warranted to resolve the debate.
