Analysis of Characteristics and Survival of Primary Cutaneous Adenoid Cystic Carcinoma of the Head and Neck.

BACKGROUND/OBJECTIVES: Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare skin tumor. The head and neck (H&N) is the most common anatomical location. Due to limited published cases, its clinical course and management are not well understood. METHODS: The National Cancer Database (NCDB) was queried for all cases of H&N PCACC diagnosed from 2004 to 2016. Kaplan-Meier (KM) and Cox proportional hazards models were used to determine clinicopathological and treatment factors associated with survival outcomes. RESULTS: A total of 201 cases were analyzed. The average age of diagnosis was 57.7 years (± SD 15.8). There was a female predilection (57.7%; P < .05) with the most common primary site being the ear (58.2%). The average tumor size was 15.9 mm in diameter. The most common treatment was surgery alone (51.7%) with wide local excision being the common surgery performed (36.3%). 5-year and 10-year OS were 87.0% and 76.0%, respectively. A total of 65.8% of cases were localized (Stage I and II). KM analysis indicated that gender, age, insurance status, Charlson-Deyo Comobordity Score, and stage were significant predictors of OS (P < .05). Cox proportional hazards analysis revealed that patients with both private (HR 0.11, 95%CI [0.019-0.670]; P = .02) and government (HR 0.12, 95%CI [0.019-0.972]; P = .03) health insurance had a significantly decreased hazard of death than patients who were uninsured. Increasing age was associated with an increased hazard of death (HR 1.06, 95%CI [1.016-1.110]; P = .01). CONCLUSION: This study represents the largest cohort of H&N PCACC studied to date and provides important clinicopathologic information for this rare tumor. Additionally, our results emphasize the importance of health insurance as an independent predictor of survival in PCACC.

Time is Money: Relative Value Units and Operative Time in Otolaryngology.

OBJECTIVES: Physician compensation for procedures is typically rooted in the work relative value unit (wRVU) system. Operative time is one of the factors that goes into the determination of wRVU assignment. There should be consistency between the wRVU/hr rate, irrespective of average operative time required to perform certain procedures. We investigate if wRVU assignment for otolaryngology procedures adequately accounts for increased operative time. STUDY DESIGN: Retrospective analysis of a surgical database. METHODS: NSQIP was queried from 2015-2018 for the top 50 most frequently performed otolaryngology Current Procedural Terminology (CPT) codes completed as standalone procedures. Median operative time was determined for each CPT code, and wRVU/hr was calculated. Correlations between operative time, wRVU, and wRVU/hr were investigated using linear regression analysis. A secondary analysis using complication rate as an indicator for procedure complexity was performed to examine the relation between wRVUs and complication rates. RESULTS: Fifty CPT codes containing 64,084 patients where only one code was reported were included in this analysis. The median operative time was 84 minutes, median wRVU was 11.23, and median wRVU/hour was 7.96. Linear regression analysis demonstrated a strong positive correlation between operative time and wRVU assignment (R2 = 0.805, P < .001). Further analysis found no correlation between operative time and wRVU/hr (R2 = 0.008, P = .525). Linear regression of wRVU/hr and complication rate showed a statistically significant positive correlation (R2 = 0.113, P = .017). CONCLUSION: This analysis suggests that compensation for otolaryngology procedures is positively correlated with operative time. Surgeries where more than one code is reported could not be evaluated, thus excluding some common combination of procedures performed by otolaryngologists.
