Survival Outcomes in Sinonasal Poorly Differentiated Squamous Cell Carcinoma.
Sinonasal squamous cell carcinoma (SCC) is rare with no consensus on treatment regimen. Our goal is to analyze treatment outcomes in poorly differentiated SCC (PDSCC) using a large national database.
Retrospective database study.
The National Cancer Database was queried for sinonasal invasive SCC, grade 3 (poorly differentiated) from 2004 to 2014. Patient demographics and tumor and treatment characteristics were tabulated. Kaplan-Meier (KM) analysis was performed to compare overall survival (OS) between histology subtype and primary site. Multivariable Cox proportional hazards regression was performed for statistical analysis of treatment regimen on OS.
A total of 1,074 patients were identified. The maxillary sinus was the most common site (45%). T4 tumors were observed in 50% of patients, with most patients treated at high-volume facilities (77%). In KM analysis, spindle cell SCC histological subtype, primary tumors of the maxillary sinus, and poorly differentiated grade had worse OS. In our Cox-PH model, higher T stage and age were associated with worse OS. Those treated at a high-volume facility and those who underwent surgical resection followed by adjuvant radiation had improved OS. Chemotherapy within the treatment regimen did not confer survival benefit except in surgical patients when positive margins were present, and surgery with adjuvant chemoradiation trended toward improved survival.
Sinonasal PDSCC appears to be best treated at high-volume centers with surgical resection followed by adjuvant radiation. Poorly differentiated grade has worse OS compared to more differentiated tumors. Chemotherapy along with adjuvant radiation may have a role in patients with positive surgical margins.

A comprehensive comparative analysis of treatment modalities for sinonasal malignancies.
Sinonasal malignancies are a rare and heterogeneous group of tumors for which there is a paucity of robust data with which to guide management decisions. The authors used the National Cancer Data Base to better understand the presenting characteristics of these tumors and to compare outcomes by treatment modality.
The National Cancer Data Base was queried for sinonasal malignancies diagnosed between 2004 and 2012. Overall survival was assessed using multivariate analyses and propensity score matching.
A total of 11,160 patients were identified for the initial analysis. The majority were male, aged 40 to 69 years, with tumors of the nasal cavity or maxillary sinus. Squamous cell histology was most common. The majority of patients presented with advanced tumor stage but without locoregional lymph node or distant metastases. Treatment modalities were compared for squamous cell carcinomas. In multivariate analysis, compared with surgery alone, patients who received adjuvant radiotherapy (hazard ratio [HR], 0.658 [P<.001]), adjuvant chemoradiotherapy (HR, 0.696 [P = .002]), or neoadjuvant therapy (HR, 0.656 [P = .007]) had improved overall survival. Patients who received radiotherapy alone (HR, 1.294 [P = .001]) or chemotherapy alone (HR, 1.834 [P<.001]) had worse outcomes. These findings were validated in propensity score matching. It is important to note that neoadjuvant chemoradiotherapy was associated with achieving a negative surgical margin (odds ratio, 2.641 [P = .045]).
Surgery is the mainstay of therapy for patients with sinonasal malignancies, but multimodality therapy is associated with improved overall survival. Cancer 2017;123:3040-49. © 2017 American Cancer Society.

Disparities in sinonasal squamous cell carcinoma short- and long-term outcomes: Analysis from the national cancer database.
To examine sociodemographic, hospital-specific, and disease-related characteristics in relation to outcomes in sinonasal squamous cell carcinoma (SCC).
The National Cancer Database was queried for location codes corresponding to the nasal cavity and paranasal sinuses and histology codes representing SCC malignancy. Multivariate analyses were performed against short- and long-term outcomes (overall survival, days to discharge, 30-day readmission, and 30- and 90-day mortality).
The database included 5,584 sinonasal SCC patients with an overall median survival of 53.5 months (95% confidence interval [CI]: 49.7-57.8). On multivariate analysis, uninsured, Medicaid, and Medicare were independently associated with worse overall survival compared to private insurance (hazard ratio [HR]: 1.49, 95% CI: 1.22-1.82, P < .001; HR: 1.57, 95% CI: 1.34-1.85, P < .001; and HR: 1.14, 95% CI: 1.01-1.29, P = .03, respectively). Both Medicaid and Medicare were also associated with increased 30-day mortality (HR: 1.36, 95% CI: 1.76-143.29, P = .02; HR: 8.27, 95% CI: 1.66-70.88, P = .02, respectively), and Medicaid patients spent more time in the hospital following surgery (difference in days to discharge: HR: 2.09, 95% CI: 0.57-3.61, P < .01). Compared to white race, other race was associated with improved overall survival (HR: 0.79, 95% CI: 0.63-0.99, P = .04) but increased 30-day readmissions (HR: 3.85, 95% CI: 1.58-8.38, P < .01). Hispanic ethnicity was associated with increased 30-day readmissions (HR: 2.35, 95% CI: 1.08-4.75, P = .02]. The highest income bracket (≥$63,000) was associated with fewer hospital readmissions (HR: 0.33, 95% CI: 0.13-0.79, P = .01).
Sociodemographic and economic differences in outcomes of patients with sinonasal SCC cancer exist. An understanding of these differences may help minimize disparities in oncologic treatment.

Outcomes of Primary Versus Salvage Surgery for Sinonasal Malignancies: A Population-Based Analysis.
There exists a lack of consensus on the optimal sequence of treatment for many sinonasal malignancies (SNMs). This study compares the overall survival (OS) outcomes for primary surgery (PS) versus salvage surgery (SS) in SNM patients across stage, histology, and primary site.
Retrospective database review.
The National Cancer Database was queried for all SNM cases treated with multimodal surgical and nonsurgical therapy between 2004 and 2015. Logistic regression identified predictors of SS. Cox proportional hazards models evaluated predictors of mortality, and Kaplan-Meier log-rank test assessed OS outcomes.
Our SNM cohort consisted of 3,011 patients (PS = 2,804; SS = 207). SS patients had significantly longer postoperative hospital stays (P = .009) and increased rates of 30-day (P < .001) and 90-day mortality (P < .001) compared to PS. On multivariate logistic regression, predictors of undergoing SS included sinonasal undifferentiated carcinoma histology (odds ratio = 2.72; 95% confidence interval [CI]: 1.16-6.66; P = .024). On multivariate Cox proportional hazards analyses among SS patients, late-stage disease (hazard ratio [HR] = 4.80; 95% CI: 1.46-15.8; P = .01) and positive surgical margins (HR = 2.31; 95% CI: 1.29-4.13; P = .005) portended significantly worse OS. In the propensity score-matched cohort controlling for stage and histology, PS had significantly improved OS compared to SS (P = .007). Compared to SS, PS also had improved OS in subgroup analyses for patients with late-stage disease (P = .026) and squamous cell carcinoma histology (P = .006).
In our SMN cohort, PS resulted in improved OS outcomes compared to SS independent of stage and histology. Consideration may be given to primary surgical resection for SMN whenever feasible, though a targeted, individualized approach is warranted.
