Purpose: Sinonasal squamous cell carcinoma (SCC) is an aggressive malignancy frequently requiring surgical resection and adjuvant treatment. Frailty is a metric that attempts to estimate a patient's ability to tolerate the physiologic stress of treatment. There is limited work describing frailty in patients with sinonasal cancer. We sought to determine the impact of frailty on postoperative outcomes in patients undergoing treatment for sinonasal SCC.
Materials and methods: Cases of patients undergoing surgical resection of sinonasal SCC at two tertiary medical centers were queried. Demographic, treatment, and survival data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, modified 5-item frailty index (mFI-5), and the Charlson Comorbidity Index (CCI). Primary outcomes included medical and surgical complications, readmission, and length of stay (LOS).
Results: 38 patients were included. There were 23 (60.5 %) men and 15 (39.5 %) women with an average age of 59.6 ± 12.1 years. MFI-5 was 0.76 ± 0.54 and CCI was 5.71 ± 2.64. No significant association was noted between frailty measures and postoperative outcomes including 30-day medical complications, 30-day surgical complications, any 30-day complication, and readmission. Increased ASA was noted to be predictive of increased length of stay (Incidence Rate Ratio: 1.80, 95 % confidence interval [CI]: 1.16-2.83, p = 0.009).
Conclusions: We found no association between frailty metrics and worsening surgical or medical postoperative outcomes. This suggests that frailty metrics may not be as relevant for sinonasal surgery even for advanced pathologies, given the more limited physiologic impact of minimally invasive surgery.
