Cognitive Function and Patient Reported Memory Problems Following Radiation Therapy for Cancers at the Skull Base: A Cross-sectional Survivorship Study Using the Telephone Interview for Cognitive Status (TICS) and the MD Anderson Symptom Inventory-Head and Neck Module (MDASI-HN)

Using patient-reported and objective assessment tools, we sought to quantify cognitive symptoms and objective cognitive dysfunction in patients irradiated for skull base cancer.Participants were assessed using the Telephone Interview for Cognitive Status (TICS) and the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN), with subsequent analysis.Of the 122 participants analyzed, the majority (63%) had no frank detectable cognitive impairment by TICS, with frank impairment in 6%. Overall, mean patient-reported problems with memory (MDASIApproximately one third of patients had ambiguous results by TICS assessment, for whom more rigorous testing may be warranted. Moderate to severe levels of patient-reported memory complaints on the MDASI-HN module may have utility as a screening tool for cognitive dysfunction in this population.
