"On review of the available evidence, the ASCO expert panel concluded that
the majority of the evidence was insufficient to inform evidence-based recommendations for a traditional ASCO clinical practice guideline.
Thus, the recommendations were developed by a multidisciplinary group of experts and reviewed by a consensus ratings panel including radiation oncologists, neurosurgeons, members of the ASCO Breast Cancer Guidelines Advisory Group, and others using a formal consensus process based on the best available evidence and clinical experience."
