To identify racial disparities in survival outcomes among Stage III & IV patients with squamous cell carcinomas (SCCa) of the oropharynx treated with definitive radiation therapy (RT), with concurrent chemotherapy. Method This is a retrospective analysis of patients with stage III & IV SCCa of oropharynx treated with definitive RT at the State Academic Medical Center. All patients were treated to 70 Gy utilizing intensity-modulated radiation treatment (IMRT), and received concurrent chemotherapy with weekly cisplatin or cetuximab. Chisquare test was used to test the goodness of fit, overall survival (OS), and locoregional control (LRC) comparing races were generated by using Log-rank test & Kaplan-Meier method. The covariables associated with the OS and LRC were determined by the Cox regression model. A p-value of less than 0.05 was considered statistically significant. The SPSS 24.0 software (IBM Corp., Armonk, NY) was used. Results In the total 73 eligible patients, 54.8% were black, and 45.2% white patients. Stage distribution (per American Joint Committee on Cancer-AJCC 8 th Ed) between black patients vs. white patients, Stage III (45.5% vs. 54.5%) and for Stage IV (56.5% vs. 43.5%); p=0.499. Median follow-up for the entire group was 41 months (range: 4-144 months). In the univariate analysis, variables p16 status, body mass index (BMI), alcohol history and tumor subsite were found to be significant. In the multivariate analysis, only BMI has shown to be significant. Three-year LRC for black patients was 37.8% vs. 66.8% in white patients (p=0.354) and three-year OS for black patients was 51.8% vs. 80.9% for white patients (p=0.063), respectively. Five-year OS for p16 positive patients was 69.7% vs. 43% for p16 negative patients (p=0.034). Five-year OS for Stage IV black patients was 34% vs. 69.5% for Stage IV white patients (p=0.014). Conclusion Among all the co-variables examined, only BMI has shown affecting the OS outcomes; gender and BMI shown to be affecting the LRC. Racial factor appears to be significant in Stage IV patients.
This study attempted to identify disparities in outcomes between African American (AA) and Caucasian American (CA) patients treated for hypopharyngeal carcinoma at a tertiary care institution over the past 25 years. Methods An institutional review board (IRB)-approved and Health Insurance Portability and Accountability Act (HIPPA)-compliant retrospective analysis was performed on patients with squamous cell carcinoma of the hypopharynx treated at our institution between January 1994 and December 2018. Data regarding demographics, stage, treatment, and follow-up were collected. Outcomes, including median survival and overall survival, were calculated using the Kaplan-Meier method. All analyses were performed using the Social Packages for the Social Sciences (SPSS) v. 24 (IBM Corp., Armonk, NY). Results We identified 144 hypopharyngeal carcinoma patients who were treated during this period. Our patient cohort consisted of 61.8% AA and 35.4% CA (P=0.538). Overall, 96% of them presented at an advanced stage (Stages III & IV) of the disease, and only 4% presented in the early stages (Stages I & II). There was no significant difference between AA and CA patients who presented with advanced disease (96.6% vs. 94.1%). In our patient cohort, 15.3% of patients did not receive any therapy; however, 51.4%, 22.9%, and 10.4% of them underwent definitive chemoradiotherapy, definitive surgery, or palliative chemotherapy, respectively. There were no significant differences in patient racial proportions within each treatment group. The median follow-up of the entire cohort was 13 months. There was no significant difference between the median survival of AA and that of CA patients (16 months vs. 15 months; p=0.917). Moreover, there was no significant difference in the overall survival between AA and CA patients at three years (27.2% vs. 36.3%; p=0.917) and five years (20.4 % vs. 16.7 %; p=0.917). Conclusions A retrospective review of patients with hypopharyngeal cancer treated at our institution over the previous 25 years did not identify significant racial disparities regarding the stage at presentation or prognosis. This study suggests that when patients have equal access to care, they appear to have a similar prognosis despite racial differences. Further studies are needed to validate this hypothesis.
Introduction As traditional measures such as overall survival (OS) or disease-free survival (DFS) alone do not give a holistic view of the outcomes of a treatment paradigm, we determine to add the evidence of quality-adjusted life year (QALY) and disability-adjusted life year (DALY) to the outcomes of the nasopharyngeal carcinoma patients (NCP) treated with definitive chemoradiation therapy (chemoRT) with or without induction chemotherapy (induction chemo). Methods This is a retrospective analysis of 85 NCPs treated at an academic state institution. The OS estimated by the Kaplan-Meier method and the multivariate Cox regression model determined the co-variables associated with the OS. The relationship between QALYs gained and DALYs saved were calculated from age of the disease onset, duration of the disease, quality of life (QoL) and disability weights. Results Of the 85 eligible NCPs of this cohort, the disease frequency distribution per the World Health Organization (WHO) classification was 41.2% for Type-I, 42.4% for Type-II, and 16.5% for Type-III. The median follow-up (24 months). The five-year OS of patients treated with concurrent chemoRT vs . induction chemo followed by concurrent chemoRT was 54.7 vs . 14.8% for WHO Type I, 60.1 vs. 58.3% for WHO Type II, and 83.3 vs. 50.0% for WHO Type III (p=0.029). The average DALYs saved with concurrent chemoRT were 12.2 years vs. 5 years for induction chemo followed by concurrent chemoRT. The average QALYs gained with concurrent chemoRT were 6.9 years vs. 3.1 years for induction chemo followed by concurrent chemoRT. Conclusion Patients treated with concurrent chemoRT had an increased QoL when compared to induction chemo followed by concurrent chemoRT. The average DALYs saved were higher in the patients treated with concurrent chemoRT than treated with induction chemo followed by concurrent chemoRT.
