Abstract

BACKGROUND: Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome.METHODS: ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms.FINDINGS: Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1-306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively.INTERPRETATION: Using an international collaborative database we have created the first nomograms which estimate outcome in individual patients with ACC. These predictive nomograms will facilitate patient counseling in terms of prognosis and subsequent clinical follow-up. They will also identify high risk patients who may benefit from clinical trials on new targeted therapies for patients with ACC.FUNDING: None.

Abstract

Objectives To identify independent predictors of outcome in patients with adenoid cystic carcinoma (ACC) of the paranasal sinuses and skull base. Design Meta-analysis of the literature and data from the International ACC Study Group. Setting University-affiliated medical center. Participants The study group consisted of 520 patients, 99 of them from the international cohort. The median follow-up period was 60 months (range, 32 to 100 months). Main Outcome Measures Overall survival (OS) and disease-specific survival (DSS). Results The 5-year OS and DSS of the entire cohort were 62% and 67%, respectively. The local recurrence rate was 36.6%, and the regional recurrence rate was 7%. Distant metastasis, most commonly present in the lung, was recorded in 106 patients (29.1%). In the international cohort, positive margins and ACC of the sphenoid or ethmoidal sinuses were significant predictors of outcome (p

Abstract

Background Endoscopic sinus surgery represents a cornerstone in the professional development of otorhinolaryngology trainees. Mastery of these surgical skills requires an understanding of paranasal sinus and skull-base anatomy. The frontal sinus is associated with a wide range of variation and complex anatomical configuration, and thus represents an important challenge for all trainees performing endoscopic sinus surgery. Methods Forty-five otorhinolaryngology trainees and 20 medical school students from 5 academic institutions were enrolled and randomized into 1 of 2 groups. Each subject underwent learning of frontal recess anatomy with both traditional 2-dimensional (2D) learning methods using a standard Digital Imaging and Communications in Medicine (DICOM) viewing software (RadiAnt Dicom Viewer Version 1.9.16) and 3-dimensional (3D) learning utilizing a novel preoperative virtual planning software (Scopis Building Blocks), with one half learning with the 2D method first and the other half learning with the 3D method first. Four questionnaires that included a total of 20 items were scored for subjects' self-assessment on knowledge of frontal recess and frontal sinus drainage pathway anatomy following each learned modality. A 2-sample Wilcoxon rank-sum test was used in the statistical analysis comparing the 2 groups. Results Most trainees (89%) believed that the virtual 3D planning software significantly improved their understanding of the spatial orientation of the frontal sinus drainage pathway. Conclusion Incorporation of virtual 3D planning surgical software may help augment trainees' understanding and spatial orientation of the frontal recess and sinus anatomy. The potential increase in trainee proficiency and comprehension theoretically may translate to improved surgical skill and patient outcomes and in reduced surgical time. [ABSTRACT FROM AUTHOR]

Abstract

Background Augmented reality (AR) fuses computer-generated images of preoperative imaging data with real-time views of the surgical field. Scopis Hybrid Navigation (Scopis GmbH, Berlin, Germany) is a surgical navigation system with AR capabilities for endoscopic sinus surgery (ESS). Methods Predissection planning was performed with Scopis Hybrid Navigation software followed by ESS dissection on 2 human specimens using conventional ESS instruments. Results Predissection planning included creating models of relevant frontal recess structures and the frontal sinus outflow pathway on orthogonal computed tomography (CT) images. Positions of the optic nerve and internal carotid artery were marked on the CT images. Models and annotations were displayed as an overlay on the endoscopic images during the dissection, which was performed with electromagnetic surgical navigation. The accuracy of the AR images relative to underlying anatomy was better than 1.5 mm. The software's trajectory targeting tool was used to guide instrument placement along the frontal sinus outflow pathway. AR imaging of the optic nerve and internal carotid artery served to mark the positions of these structures during the dissection. Conclusion Surgical navigation with AR was easily deployed in this cadaveric model of ESS. This technology builds upon the positive impact of surgical navigation during ESS, particularly during frontal recess surgery. Instrument tracking with this technology facilitates identifying and cannulation of the frontal sinus outflow pathway without dissection of the frontal recess anatomy. AR can also highlight 'anti-targets' (ie, structures to be avoided), such as the optic nerve and internal carotid artery, and thus reduce surgical complications and morbidity. [ABSTRACT FROM AUTHOR]
