Demographic trends and disease-specific survival in salivary acinic cell carcinoma: an analysis of 1129 cases.

Acinic cell carcinoma (AciCC) is a rare salivary gland malignancy that most commonly arises in the parotid gland. Characteristics of AciCC are slow growth and a long clinical course. As a rare tumor, population‐based studies are limited. We analyzed the incidence and survival for AciCC using a national population‐based database.

Readability assessment of Internet-based patient education materials related to acoustic neuromas.

Objective The objectives of this study were to assess the readability of Internet-based patient education materials related to acoustic neuromas (AN-IPEMs) by 4 widely validated readability indices, to evaluate scores against the existing sixth grade recommended reading level, and to compare the readability scores of patient education materials (PEMs) produced by professional organizations, clinical practices, hospitals, and miscellaneous sources. Materials and Methods AN-IPEMs from 67 web sites (6 professional societies, 33 clinical practices, 19 hospitals, and 9 miscellaneous) were assessed using Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Scores were then evaluated against national recommendations by 1-tailed t tests and against each other using 1-way ANOVAs. Results The average FKGL, SMOG, and Gunning FOG scores were all significantly higher than the recommended sixth grade reading level suggested by the USDHHS (p < 0.0001, single sample 1-tailed t test). Zero articles, by all indices, had a reading level equal to or below the sixth grade reading level. The FKGLs also varied between the various sources at a significant level (p = 0.01 one-way ANOVA independent samples). The average FKGLs of clinical practice and professional society AN-IPEMs were significantly higher than the average FKGLs of hospital AN-IPEMs (both p ⩽ 0.05 one-tailed t-tests assuming unequal variances). Conclusion AN-IPEMs are written at a level significantly higher than that suggested by national recommendations. Current AN-IPEMs may need to be revised in order to enhance patient comprehension.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue of the salivary glands: A population-based study from 1994 to 2009

Extranodal marginal zone lymphoma of mucosa‐associated lymphoid tissue (MALT lymphoma) arising from the salivary glands is rare.

Sinonasal adenoid cystic carcinoma: comprehensive analysis of incidence and survival from 1973 to 2009.

Sinonasal adenoid cystic carcinoma (SNACC) is a rare malignancy that most commonly arises in the maxillary sinus. Characteristics of SNACC are slow growth, perineural invasion, and long clinical course. Because it is a rare tumor, population‐based studies are limited. We analyzed the incidence and survival for SNACC using a national population‐based database.

Extranodal natural killer/T‐Cell lymphoma: A population‐based comparison of sinonasal and extranasal disease

Extranodal natural killer/T‐cell Lymphoma (ENKTL) is a rare, aggressive malignancy that preferentially affects the paranasal region. This study analyzes the demographic, clinicopathologic, incidence, and survival characteristics of sinonasal ENKTL (SN‐ENKTL) and extranasal ENKTL (EN‐ENKTL) in a comparative fashion.

Demographics and survival trends of sinonasal adenocarcinoma from 1973 to 2009.

The purpose of this work was to study the demographics and survival of patients diagnosed with sinonasal adenocarcinoma (SNAC) within the time period of 1973 to 2009 using the Surveillance, Epidemiology, and End Result (SEER) database.

Assessment of mucocele formation after endoscopic nasoseptal flap reconstruction of skull base defects

Advances in endoscopic skull base (SB) surgery have led to the resection of increasingly larger cranial base lesions, resulting in large SB defects. These defects have initially led to increased postoperative cerebrospinal fluid (CSF) leaks. The development of the vascularized pedicled nasoseptal flap (PNSF) has successfully reduced postoperative CSF leaks. Mucocele formation, however, has been reported as a complication of this technique. In this study, we analyze the incidence of mucocele formation after repair of SB defects using a PNSF. A retrospective review was performed from December 2008 to December 2011 to identify patients who underwent PNSF reconstruction for large ventral SB defects. Demographic data, defect site, incidence of postoperative CSF leaks, and rate of mucocele formation were collected. Seventy patients undergoing PNSF repair of SB defects were identified. No postoperative mucocele formation was noted at an average radiological follow-up of 11.7 months (range, 3–36.9 months) and clinical follow-up of 13.8 months (range, 3–38.9 months), making the overall mucocele rate 0%. The postoperative CSF leak rate was 2.9%. Proper closure of SB defects is crucial to prevent CSF leaks. The PNSF is an efficient technique for these repairs. Although this flap may carry an inherent risk of mucocele formation when placed over mucosalized bone during repair, we found that meticulous and strategic removal of mucosa from the site of flap placement resulted in a 0% incidence of postoperative mucocele formation in our cohort.

Readability Assessment of Internet-Based Patient Education Materials Related to Parathyroid Surgery.

Objectives: Patient education is critical in obtaining informed consent and reducing preoperative anxiety. Written patient education material (PEM) can supplement verbal communication to improve understanding and satisfaction. Published guidelines recommend that health information be presented at or below a sixth-grade reading level to facilitate comprehension. We investigate the grade level of online PEMs regarding parathyroid surgery. Methods: A popular internet search engine was used to identify PEM discussing parathyroid surgery. Four formulas were used to calculate readability scores: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Gunning Frequency of Gobbledygook (GFOG), and Simple Measure of Gobbledygook (SMOG). Results: Thirty web-based articles discussing parathyroid surgery were identified. The average FRE score was 42.8 (± 1 standard deviation [SD] 16.3; 95% confidence interval [CI], 36.6-48.8; range, 6.1-71.3). The average FKGL score was 11.7 (± 1 SD 3.3; 95% CI, 10.5-12.9; range, 6.1-19.0). The SMOG scores averaged 14.2 (± 1 SD 2.6; 95% CI, 13.2-15.2; range, 10.7-21.9), and the GFOG scores averaged 15.0 (± 1 SD 3.5; 95% CI, 13.7-16.3; range, 10.6-24.8). Conclusion: Online PEM on parathyroid surgery is written above the recommended sixth-grade reading level. Improving readability of PEM may promote better health education and compliance.

Efficacy of Elective Neck Dissection in T1/T2N0M0 Oral Tongue Squamous Cell Carcinoma A Population-Based Analysis

Objective/Hypothesis The aim of this population-based study is to analyze the survival benefits of elective neck dissection (END) over neck observation in T1/T2N0M0 oral tongue squamous cell carcinoma (OT-SCC) cases. Study Design Retrospective administrative database analysis. Subjects and Methods The SEER database (Surveillance, Epidemiology, and End Results) was queried for patients diagnosed with T1/T2N0M0 OT-SCC from 1998 to 2011. Data included patient demographics, initial treatment, and survival outcomes. The Kaplan-Meier model and the Cox proportional hazards model were utilized for survival analysis. Results Out of 7010 T1/T2N0M0 cases, END was performed in 1770 T1 and 950 T2 cases, and the neck was observed in 3278 T1 and 1001 T2 cases. Significantly poorer 5-year disease-specific survival (DSS) rates were noted for the neck observation group when compared with the END group for tumors with moderately differentiated (72.1% vs 86%, P < .0001) and poorly differentiated or undifferentiated (55.6% vs 71.5%, P = .0001) histologic grades. No significant survival benefit was seen between the END group and the neck observation group when tumor size was <1 cm, regardless of histology grade. However, those with tumors >1 cm had a significantly better 5-year DSS with END, except for the well-differentiated tumor cohort, which showed improved survival only when the tumors were >2 cm (5-year DSS: END vs neck observation, 83.5% vs 65.7%, P = .0002). Conclusion END improves DSS versus neck observation in T1/T2N0M0 OT-SCC patients with moderately differentiated, poorly differentiated, or undifferentiated histologic grade tumors >1 cm. Those with well-differentiated tumors benefited from END only when tumor size was >2 cm.
