Prophylactic Cranial Irradiation Versus Surveillance: Physician Bias and Patient-centered Decision-making.

An original work in this month's issue of Clinical Lung Cancer highlights the role of physician bias in the decision to recommend prophylactic cranial irradiation (PCI) to patients with small-cell lung cancer, and presents a patient decision aid to facilitate discussion. After decades of clinical trials, we've learned that PCI can significantly decrease the risk of brain metastases and possibly improve survival. However, PCI is also associated with negative impacts on cognition and quality of life. At present, there is no consensus on how to balance these risks and benefits. Understanding and exploring these issues in a structured fashion offers an opportunity to return decision-making to patients, incorporating their values and priorities.
