RESUMO
INTRODUCTION: Sinonasal carcinomas (SNCs) are rare neoplasms that are often diagnosed at advanced stages due to asymptomatic growth of tumours in the spaces of the sinonasal complex. Treatment is associated with high morbidity, and outcomes have only improved slightly in the past few decades despite advancements in treatment modalities. The purpose of this study is to evaluate the efficacy and safety of treatment at our institution. METHODS: This retrospective cohort study analysed patients who received definitive treatment at the Prince of Wales Hospital (POWH), Sydney, for non-metastatic SNC. Patients with non-carcinoma and olfactory neuroblastoma pathology were excluded. Data were collected from the POWH electronic patient database. Survival functions were calculated through Kaplan-Meier analysis, and multivariate analysis for prognostic factors was performed through Cox regression. RESULTS: Seventy-five patients from 1994 to 2016 were eligible for analysis. Overall 5-year local control (LC), ultimate local control (ULC), overall survival (OS) and cancer-specific survival (CSS) were 76 ± 6%, 80 ± 5%, 69 ± 6% and 77 ± 5%, respectively. On multivariate analysis, clinical stage was prognostic for LC and primary site was prognostic for OS and CSS. Lymphovascular invasion and tumour inoperability were also predictive of CSS. CONCLUSION: Survival and local control rates at our centre were greater than those reported in the literature. Early-stage patients treated with surgery alone had excellent oncologic outcomes. Radical surgery with postoperative radiation provides the best outcome in the setting of advanced disease.

Immune checkpoint inhibitors (ICIs) have demonstrated promising results in a variety of advanced cancer types. The phenomenon of hyperprogressive disease (HPD) has only been documented in recent years, however, there have been no reports of HPD in hepatocellular carcinoma. We present a case series of six patients with advanced hepatocellular carcinoma treated with ICIs who demonstrated rapid radiological progression, this was confirmed by comparing tumor growth rates before and during treatment with HPD defined as tumor growth rateratio ≥2. Although ICIs have demonstrated profound efficacy in advanced cancer, they might also be responsible for HPD in a small subset of patients. The ability to predict treatment response to ICI is thus of importance in protecting patients from the deleterious effects of HPD.
