5-3 h post-administration. Blood THC levels were significantly correlated with some pharmacodynamic drug effects, but were substantially lower than what is typically observed after cannabis inhalation. CONCLUSION Ingestion of oral cannabis dose-dependently altered subjective drug effects and impaired cognitive performance. Unlike inhaled forms of cannabis for which acute effects occur almost immediately, effects of oral cannabis were considerably delayed. In an era of legalization, education about the time course of drug effects for cannabis edibles is needed to facilitate dose titration and reduce acute overdose incidents. V.OBJECTIVES Soft tissue sarcomas of the head and neck (HNSTS) show various histological types and clinical behaviour. Recently, the 8th edition of the American Joint Committee on Cancer (AJCC) proposed a staging system for HNSTS independent of other body soft tissue sarcomas, which requires validation. Therefore, we evaluated the prognostic factors for the survival of HNSTS patients through a comparison between previous and current AJCC staging systems. MATERIALS AND METHODS This study involved 135 consecutive HNSTS patients who underwent primary surgery, chemoradiotherapy or chemotherapy. Patients were grouped into staged (S) and not staged (NS) cancer according to the AJCC 8th edition staging. Cox proportional-hazard regression analyses were used to identify factors associated with overall survival (OS), and progression-free survival (PFS) in all, S or NS patients. RESULTS Median follow-up period was 75 months and the 5-year OS and PFS rates of all patients were 67.8% and 53.4%, respectively, which was similar between S and NS groups. Age, tumour size and grade, overall stage (7th edition) and resection margin were the significant prognostic factors for OS and PFS in all patients and NS group (all P less then 0.05), whereas positive resection margin was the only significant factor for OS and PFS in the S group (P less then 0.001). While OS was poorly discriminated among different 8th edition T-categories, different 7th edition showed good discrimination among overall stages in all patients and the NS group. CONCLUSION The revised staging system may not provide an improved risk stratification for survival of HNSTS patients. OBJECTIVE Thus far, there is no final conclusion on the treatment of local recurrent nasopharyngeal carcinoma (lrNPC) patients. Selleckchem 5-Fluorouracil Herein, we developed a nomogram which combined prognostic biomarkers to predict clinical outcome and guide individual treatment. MATERIALS AND METHODS From 2006 to 2016, 303 patients with lrNPC were retrospectively reviewed. Overall survival (OS) was the primary endpoint. The nomogram was established with the significant prognostic factors (P less then 0.05) selected by multivariate analysis using Cox regression model. Harrell Concordance Index (C-index), calibration curves, and decision curve analysis (DCA) were applied to evaluate this model. RESULTS Four independent prognostic factors (age, hypertension, relapsed T (rT) stage, and Epstein-Barr virus DNA) identified from multivariable analysis were included into the nomogram. The C-index of the nomogram was 0.687. The calibration curves for 1-, 3-, and 5-year OS rate showed satisfactory agreements between the predicted and actual values. The decision curve analysis also exhibited a preferable net benefit of this model. All patients were subdivided into three risk groups based on the nomogram. Local treatment was associated with higher OS than palliative chemotherapy alone in the low (P less then 0.001) and intermediate-risk groups (P = 0.001). However, no significant difference was observed between different treatment methods in the high-risk group (P = 0.176). CONCLUSION We established the nomogram for patients with lrNPC to predict OS and guide individual treatment, which showed satisfactory performance in accuracy, discrimination capability, and clinical utility. BACKGROUND Maxillary sinus cancer is a rare disease with heterogeneous biologic behavior. The pattern of neurovascular invasion is known to be an important prognosticator in head and neck cancers, but has not been studied in maxillary malignancies. MATERIALS AND METHODS Patients undergoing surgery-based treatment with curative intent for a malignancy of the maxillary sinus at the Unit of Otorhinolaryngology - Head and Neck Surgery of the University of Brescia between November 2000 and October 2018 were included. A description of the characteristics of the patients, tumors, and treatments has been performed along with uni- and multi-variate analysis of prognostic factors. Tumors were classified based on the presence of perineural (P0/P1) and lymphovascular invasion (V0/V1) in 4 categories P0V0, P1V0, P0V1, and P1V1. RESULTS One hundred-thirty-eight patients were included. Mean age at surgery was 61.0 years. Most patients (60.1%) were affected by non-salivary carcinomas, and most tumors (73.9%) were high-grade cancers. One hundred-seven (77.5%) tumors were classified as pT4. The large majority of patients received bi- or tri-modality treatment. Sixty-three (45.7%) cases were classified as P0V0, 32 (23.2%) as P1V0, 7 (5.1%) as P0V1, and 36 (26.1%) as P1V1. T category, nodal status, and neurovascular invasion were significantly associated with prognosis. Perineural and lymphovascular invasion were associated with the topographical growth of the tumor. CONCLUSIONS Maxillary cancer is often diagnosed at an advanced stage and in most cases requires a multimodal approach. Perineural and lymphovascular invasion are frequent and have a different impact on prognosis and topographical extension of the tumor. BACKGROUND AND PURPOSE Customized mouth-opening-tongue-depressing-stents (MOTDs) may reduce toxicity in patients with head and neck cancers (HNC) receiving radiotherapy (RT). However, making MOTDs requires substantial resources, which limits their utilization. Previously, we described a workflow for fabricating customized 3D-printed MOTDs. This study reports the results of a prospective trial testing the non-inferiority of 3D-printed to standard and commercially-available (TruGuard) MOTDs as measured by patient reported outcomes (PROs). MATERIALS AND METHODS PROs were collected at 3 time points (t1) simulation, (t2) prior to RT, (t3) between fractions 15-25 of RT. Study participants received a 3D-printed MOTDs (t1, t2, t3), a wax-pattern (t1), an acrylic-MOTDs (t2, t3) and an optional TruGuard (t1, t2, t3). Patients inserted the stents for 5-10 min and completed a PRO-questionnaire covering ease-of-insertion and removal, gagging, jaw-pain, roughness and stability. Inter-incisal opening and tongue-displacement were recorded.
