Nasopharyngeal carcinoma in a non-endemic country-Validation of the new NPC staging system.

BACKGROUND: Nasopharyngeal carcinoma (NPC) staging has recently been updated, with the eighth edition of the AJCC/UICC. In the last ten years, Intensity Modulated Radiotherapy (IMRT) has become a standard treatment for NPC. The authors aim to assess the benefits of the new AJCC staging system in predicting prognosis, as well as the improvement in survival outcomes in the IMRT era, in non-edemic population. METHODS: Retrospective study selecting patients treated for NPC between January 2009 and December 2019 in a cancer treatment center in Portugal. Initial TNM staging (according to the seventh edition of the AJCC/UICC) was collected and each patient was restaged according to the new TNM staging system. Overall survival (OS) and Distant Metastasis Free Survival (DMFS) stratified by T and N classification and stage (according to the both TNM staging systems) were analyzed. Univariate and multivariate analysis was performed to evaluate which factors influence OS and DMFS. Data in this series was compared with a previous report from the same institution, before IMRT standard use. RESULTS: 113 patients were included, averaging 53.74 (±1.4) years old. With the new TNM staging, 5 patients were downstaged and 3 patients were upstaged. Over a median follow-up time of 41 months, the 5-year OS and DMFS were 77% and 79.8%, respectively. Neither the seventh nor the eighth editions of the AJCC/UICC staging system had good overall discrimination between each T classification OS and DMFS curves. Both the seventh and the eighth editions of the AJCC/UICC staging system had statistically significant overall discrimination between each N group and each stage group classification OS curves. Only N classification predicted OS in multivariate analysis. When comparing to a previous report from the same institution, OS has not improved majorly, especially in locoregionally advanced disease. CONCLUSIONS: TNM staging still presents limitations in adequately predicting OS and DMFS.

Antecedentes: La estadificación del carcinoma nasofaríngeo (NPC, por sus siglas en inglés) se ha actualizado recientemente, con la octava edición del AJCC/UICC. En los últimos 10 años, la radioterapia de intensidad modulada (IMRT, por sus siglas en inglés) se ha convertido en un tratamiento estándar para la NPC. Los autores pretenden evaluar los beneficios del nuevo sistema de estadificación del AJCC en la predicción del pronóstico, así como la mejora en los resultados de supervivencia en la era de la IMRT, en una población non endémica.MétodosEstudio retrospectivo de selección de pacientes tratados por NPC entre enero de 2009 y diciembre de 2019 en un centro de tratamiento del cáncer en Portugal. Se recopiló la estadificación TNM inicial (según la séptima edición del AJCC/UICC) y se reestadificó cada paciente de acuerdo con el nuevo sistema de estadificación TNM. Se analizaron la supervivencia global (SG) y la supervivencia libre de metástasis a distancia (SLMD) estratificadas por clasificación T y N y estadio (según ambos sistemas de estadificación TNM). Se realizó un análisis univariante y multivariante para evaluar qué factores influyen en la SG y la SLMD. Los datos de esta serie se compararon con un informe anterior de la misma institución, antes del uso estándar de la IMRT.ResultadosSe incluyeron 113 pacientes, con una edad promedio de 53,74 (±1,4) años. Con la nueva estadificación TNM, 5 pacientes aumentaron estadio y 3 pacientes disminuyeron estadio. Durante una mediana de tiempo de seguimiento de 41 meses, la SG y la SLMD a 5 años fueron del 77 y del 79,8%, respectivamente. (AU)

The Spare Roof Technique as a New Approach to the Crooked Nose.

Background: The literature reporting outcomes in crooked nose patients submitted to surface dorsal preservation techniques is almost nonexistent. Objectives: To evaluate aesthetic and functional outcomes in crooked nose patients undergoing rhinoplasty with the Spare Roof Technique (SRT). Methods: Prospective, interventional, and longitudinal study performed on patients presenting a crooked nose undergoing primary rhinoplasty by SRT. The validated Portuguese version of the Utrecht Questionnaire for Outcome Assessment in Aesthetic Rhinoplasty and a visual analog scale were used to assess aesthetic and functional outcomes, respectively. Patients completed the questionnaire preoperatively and again 3 and 12 months postoperatively. Results: The study population included 54 Caucasian Mediterranean patients (34 female), mean aged 34.5 years. The SRT resulted in a highly significant improvement in all questions regarding subjective body image in relation to nasal appearance and subjective nasal function. The mean preoperative aesthetic Utrecht Questionnaire sum score was 13.4 (standard deviation [SD] 0.5), which improved to 9.2 (SD 0.15) at 12 months postsurgery (p < 0.001). Conclusions: The SRTa is a reliable technique that can help deliver consistently good results in reduction rhinoplasty in patients with a crooked nose.

The Caucasian Hump: Radiologic Study of the Osteocartilaginous Vault versus Surface Anatomy. Clinical Implications in Structured and Preservation Rhinoplasty.

BACKGROUND: The relation between the osteocartilaginous nasal vault and nasal hump characteristics has not been fully investigated. METHODS: Measurements were collected from computed tomographic nasal scans in the midsagittal plane in adult Caucasian patients seeking rhinoplasty because of nasal hump from January of 2015 to December of 2018. Measurements were compared to those of sex- and age-matched patients not seeking rhinoplasty (control group). Patients with other significant nasal deformities were excluded. The correlations between nasal hump length, height, and osteocartilaginous nasal vault measurements were assessed. Distances from the beginning of the nasal hump to the kyphion and ethmoidal points were measured as well. The location of the nasal hump apex in relation to the keystone area structures was detailed. RESULTS: The study included 134 Caucasian patients, with 67 presenting nasal hump. The mean patient age was 32.9 years and 69.6 percent were female patients. Nasal hump measured a mean 17 ± 2.7 mm in length and 1.8 mm (range, 1.1 to 3.8 mm) in height. Nasal hump length correlated with nose length and nasal bone length. Nasal hump height correlated with nose length and the angle over the kyphion. In 97 percent of patients, the nasal hump began caudal to the ethmoidal point, and in all patients, the kyphion was underneath the nasal hump. The nasal hump is not a symmetric structure and, in all patients, its apex was situated above the septal cartilage. CONCLUSIONS: The nasal hump characteristics are mainly attributable to the septal cartilage, and this should be the cornerstone of any dorsal hump reduction strategy. The caudal aspect of the nasal bones contributes to the nasal hump, whereas the posterior ethmoidal plate rarely does.

Middle Vault Changes After Humpectomy by Spare Roof Technique Versus Component Dorsal Hump Reduction.

Objectives: To compare the effect of two different humpectomy techniques in the internal nasal valve (INV) angle in human anatomic specimens. Methods: Seven human anatomic specimens (14 heminoses) were included. A strip of subdorsal septal cartilage was removed and, in each nose, the right side of the middle roof lied intact over and was sutured to the septal cartilage (spare roof technique [SRT]), whereas in the left side the upper lateral cartilage was folded and sutured to the septal cartilage (component dorsal hump reduction [CDHR]). The INV angle was measured pre- and postoperatively. Results: Mean age of the specimens was 69.86 (60-80) years. Five were female. CDHR resulted in a mean change of +1.71 ± 3.12° (p = 0.197), +0.62 ± 6.89° (p = 0.817) and +6.97 ± 6.84° (p = 0.036) after resection of 2, 4, and 6 mm of septal cartilage, respectively. SRT resulted in a mean change of +1.27 ± 2.37° (p = 0.207), +6.89 ± 1.19° (p < 0.001), and +12.55 ± 1.79° (p < 0.001) after resection of 2, 4, and 6 mm of septal cartilage, respectively. In SRT, the amount of septal cartilage resection presented a significant correlation with change in INV angle (r = 0.813, p < 0.001). Conclusions: In this human anatomic study, SRT significantly increased INV angle.
