RESUMO
BACKGROUND: We assessed glioma incidence and disparities in postglioma survival rate in the Olmsted County, Minnesota, population. METHODS: This population-based study assessed the incidence of pathologically confirmed primary gliomas between January 1, 1995, and December 31, 2014. Age- and sex-adjusted incidence rates per 100 000 person-years were calculated and standardized to the US white 2010 population. We compared incidence trends of glioma during our study period with previously published Olmsted County data from 1950 to 1990. We assessed postglioma survival rates among individuals with different socioeconomic status (SES), which was measured by a validated individual HOUsing-based SES index (HOUSES). RESULTS: We identified 135 incident glioma cases (93% white) with 20 pediatric (50% female) and 115 adult cases (44% female). Overall incidence rate during our study period, 5.51 per 100 000 person-years (95% CI: 4.56-6.46), showed no significant changes and was similar to that seen in 1950 to 1990, 5.5 per 100 000 person-years. The incidence of pediatric (age < 20 years) glioma was 2.49 (95% CI: 1.40-3.58), whereas adult glioma incidence was 6.47 (95% CI: 5.26-7.67). Among those with grade II to IV gliomas, individuals with lower SES (< median HOUSES) had significantly lower 5-year survival rates compared to those with higher SES, adjusted hazard ratio 1.61 (95% CI: 1.01-2.85). CONCLUSION: In a well-defined North American population, long-term glioma incidence appears stable since 1950. Significant socioeconomic disparities exist for postglioma survival.
RESUMO
PURPOSE: A primary brain tumor patient and caregiver survey was completed to investigate interest in brief support opportunities, focused on education, memory training, and healthy coping, during a routine clinical visit and at 3-month follow-up. METHODS: Patients with primary brain tumors receiving care in the Radiation Oncology Department at Mayo Clinic Rochester and their caregivers were recruited to complete the survey between June 2008 and September 2009. RESULTS: Both patients and their caregivers expressed greatest interest in education about brain tumors and cognitive effects of treatment. Interest in support opportunities targeting education, memory training, or healthy coping was low to modest. Bimodal distributions were found for almost all the support opportunities, revealing subgroups of patients and caregivers with high interest in such sessions. Overall, ratings of interest did not differ over time. CONCLUSIONS: Patients with primary brain tumors and their caregivers expressed most interest in education about their disease and potential cognitive effects of treatment. It appears that subgroups of patients and caregivers have very high interest in brief support opportunities. Identifying these subgroups of patients and families will allow targeted interventions focused on their needs and make the best use of limited resources.
