ABSTRACT

England's influenza vaccination programme targets persons with clinical risk factors, pregnant women, those aged 65 years and older and children. Low vaccine uptake amongst primary school children was previously found to be significantly associated with increasing deprivation, Black or Minority Ethnic (BME) and certain religions. It is unknown whether these population predictors are associated with vaccine uptake in other groups. GP level data for target groups during the 2015/16 and 2016/17 seasons were linearly regressed against various factors to determine potential predictors associated with variation in uptake. Adjusted uptake for 2-4 year olds during both seasons was more than 11% lower in the most deprived decile and more than 3% lower in 34%+ BME populations compared to the least deprived and non-BME populations. Pregnant women in deprived areas had significantly lower vaccine uptake than in non-deprived areas. Patients 16-64 years old at risk showed no significant variation in uptake by deprivation, whereas patients 65 years and older had more than 3% higher vaccine uptake in the least deprived populations than the most deprived populations. Areas with the highest Muslim and BME populations had a significantly higher vaccine uptake among patients ages 16 to under 65 years old in a clinical risk group than non-Muslim and non-BME populations during both seasons. Population-factors have different effects on vaccine uptake for the various target groups. These findings support segmenting public health activities to improve vaccine uptake and reduce inequalities.

ABSTRACT

BACKGROUND: Currently, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy are accepted treatments for surgically resectable appendiceal epithelial neoplasms. However, for nonsurgical candidates, systemic treatment may be considered. The purpose of this analysis was to determine the benefit of biologic therapy (anti-vascular endothelial growth factor and anti-epidermal growth factor receptor) in addition to systemic chemotherapy in this select patient population. METHODS: The MD Anderson Cancer Center tumor registry was retrospectively reviewed for systemic treatment-naive appendiceal epithelial neoplasm patients registered between January 2000 to July 2007 for prior cytoreductive surgery and hyperthermic intraperitoneal chemotherapy status, histologic grade, signet ring pathology, systemic chemotherapy, biologic therapy, tumor markers (carcinoembryonic antigen, carbohydrate antigen [CA] 125, and/or CA19-9), progression-free survival (PFS), overall survival (OS), and disease control rate. Kaplan-Meier method, log-rank, and Cox proportional hazard regression models were used for statistical analysis. RESULTS: A total of 353 patients were identified; 130 patients met the inclusion criteria. Fifty-nine patients received biologic therapy. The use of the anti-vascular endothelial growth factor (VEGF) agent bevacizumab improved both OS (42 months vs. 76 months, hazard ratio 0.49 [95 % confidence interval 0.25-0.94] P = 0.03) and PFS (4 months vs. 9 months, hazard ratio 0.69 [95 % confidence interval 0.47-0.995], P = 0.047) for all histologic subtypes. Moderately differentiated tumors had an improved PFS relative to well-differentiated tumors, 9 months versus 3 months (P = 0.05). CONCLUSIONS: Bevacizumab in combination with chemotherapy appears to play a role in surgically unresectable appendiceal epithelial neoplasm patients, with an improvement in PFS and OS. Anti-VEGF agents should be strongly considered in the management of patients with higher-grade appendiceal epithelial neoplasms who are suboptimal candidates for surgical resection.

ABSTRACT

BACKGROUND: Poorly differentiated and signet ring cell adenocarcinomas of the appendix represent a subset with aggressive tumor biology and poor outcomes with few studies evaluating the impact of systemic chemotherapy and cytoreductive surgery (CRS). PATIENTS AND METHODS: A retrospective chart review of patients with either poorly differentiated and signet ring cell appendiceal adenocarcinomas was completed from 1992 to 2010. RESULTS: One hundred forty-two patients were identified. Seventy-eight patients with metastatic disease received chemotherapy. Radiographic response was 44%, median progression-free survival (PFS) was 6.9 months, and median overall survival (OS) was 1.7 years. In multivariate analysis, response to chemotherapy [hazard ratio (HR) 0.5; P = 0.02] predicted improved PFS, and complete CRS (HR 0.3; P = 0.004) predicted improved OS. Patients who underwent complete CRS (n = 26) had a median relapse-free survival (RFS) of 1.2 years and a median OS of 4.2 years. In multivariate analysis for this subset, complete cytoreduction score of 0 was significantly correlated with improved RFS (HR 0.07; P = 0.01) and OS (HR 0.02; P = 0.01). CONCLUSIONS: Systemic chemotherapy appears to be a viable treatment option for patients with metastatic poorly differentiated and signet ring cell appendiceal adenocarcinomas. Complete CRS is associated with improved RFS and OS, though part of this benefit likely reflects the selection of good tumor biology.
