Patient-Reported Outcomes in Sinonasal and Skull Base Malignancy: An Assessment of Study Quality and Clinical Relevance.

Abstract

Sinonasal and skull base malignancies can cause significant adverse effects on functional status and survival. The goal of this study was to systematically review the published literature of patient-reported outcomes pertaining to treatment of sinonasal and skull base malignancy. A systematic literature search of Medline was conducted with PubMed to identify studies that assessed patient-reported outcomes in patients with sinonasal or skull base malignancy. Patient-reported outcomes studies with at least 10 patients published in English from January 2000 to April 2017 were included. Criteria from International Society for Quality of Life guidelines and criteria unique to sinonasal and skull base malignancies were used to calculate a composite score for each article. Studies with the top 33% of scores were categorized as high quality articles. Twenty-two articles met inclusion/exclusion criteria. Three studies (14%) reported a priori hypothesis. Eleven (50%) assessed specific quality of life domains and 10 studies (45%) performed statistical analysis on these domains. Specific symptoms were assessed in up to 32% of studies. Eight studies were characterized as high quality; these studies had higher sample sizes and more often assessed patient-reported outcomes prior to treatment compared to low quality studies. The goal of the current study was to evaluate the quality of the current patient-reported outcomes literature on sinonasal and skull base malignancies. Areas of improvement for future studies include analysis of individual domains and disease-specific symptoms, reporting a priori hypotheses, and collecting preoperative and longitudinal patient-reported outcomes data.
