Global survival trends for brain tumors, by histology: analysis of individual records for 556,237 adults diagnosed in 59 countries during 2000-2014 (CONCORD-3)

BACKGROUND

Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology.

METHODS

We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator.

RESULTS

The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults.

CONCLUSIONS

To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

The Psychological Consequences of the COVID-19 Pandemic in Adults Treated for Childhood Cancer

Background: Compared with the general population, childhood cancer survivors (CCS) could be at greater risk of psychological distress following the emergence of the COVID-19 pandemic. Purpose: This cross-sectional study assessed the psychological consequences of COVID-19 on the mental health of CCS. Design and participants: In December 2020, we interviewed through an online self-report questionnaire, 580 5-year CCS participating in the French Childhood Cancer Survivor Study (FCCSS) cohort. Methods: We first compared the mental health score of CCS with that observed in the French general population of the same age and gender. Subsequently, we studied predictors of the mental health score of CCS. Results: External comparisons revealed that the mental health score of CCS was similar to that of the general population. Among CCS, almost 42% stated that their psychological state had been worse during the lockdown. Predictors of poorer mental health included, among others, female gender, reporting a change in the occupational situation, having a relative who had been hospitalized or had died following COVID-19, and a greater perceived infection risk. Interpretation and Implications: Given the pre-existing vulnerability of some CCS to mental distress, the additional psychological consequences of COVID-19 in vulnerable survivors should receive attention from health care providers.

Risk perceptions and health care use in the era of the COVID-19 pandemic in adults treated for childhood cancer

Purpose

During the COVID-19 pandemic, childhood cancer survivors (CCS) may have felt more at risk of having severe consequences of COVID-19 and therefore may have been more likely to defer their health care use. We aimed to assess the risk perceptions of CCS related to COVID-19 (perceived infection risk, perceived risk of experiencing a severe illness in the event of infection), and their forgoing of health care during the year 2020.

Methods

In December 2020, we interviewed through an online self-report questionnaire 580 5-year CCS participating in the French Childhood Cancer Survivor Study (FCCSS) cohort. Combining clinical and patient-reported outcomes, we studied predictors of perceived risks related to COVID-19 and forgoing health care.

Results

Overall, 60% of respondents stated that COVID-19 could have severe consequences for their health if infected. Survivors with a cardiovascular disease and those who felt more at risk of being infected were more likely to think that COVID-19 could have severe health consequences for them. Moreover, 30% of respondents seeking care declared they had forgone at least one medical appointment in 2020. Forgoing medical appointments was more common among CCS who reported a deterioration in their financial situation in 2020 and those who felt more at risk of being infected.

Conclusions

This study shows that a considerable proportion of survivors had forgone medical appointments because of the pandemic; forgoing care was more frequent among the most socioeconomically disadvantaged survivors.

Implications for cancer survivors.

This study presents data hitherto absent in the literature and suggests the need to develop telehealth to ensure appropriate long-term follow-up of CCS.

Factors associated with 5- and 10-year survival among a recent cohort of childhood cancer survivors (France, 2000-2015)

BACKGROUND

Childhood cancer survival currently exceeds 80 % five years after diagnosis in high-income countries. In this study, we aimed to describe long-term trends and to investigate socioeconomic and spatial disparities in childhood cancer survival.

METHODS

The study included 28,073 cases recorded in the French National Registry of Childhood Cancers from 2000 to 2015. Contextual census data (deprivation indices, population density, spatial accessibility to general practitioners) were allocated to each case based on the residence at diagnosis. Overall survival (OS) and conditional 10-year OS for 5-year survivors were estimated for all cancers combined and by diagnostic group and subgroup. Comparisons were conducted by sex, age at diagnosis, period of diagnosis, and contextual indicators. Hazard ratios for death were estimated using Cox models.

RESULTS

All cancers combined, the OS reached 82.8 % [95 % CI: 82.4-83.3] at 5 years and 80.8 % [95 % CI: 80.3-81.3] at 10 years. Conditional 10-year OS of 5-year survivors reached 97.5 % [95 % CI: 97.3-97.7] and was higher than 95 % for all subgroups except osteosarcomas and most subgroups of the central nervous system. In addition to disparities by sex, age at diagnosis, and period of diagnosis, we observed a slight decrease in survival for cases living in the most deprived areas at diagnosis, not consistent across diagnostic groups.

CONCLUSION

Our results confirm the high 5-year survival for childhood cancer and show an excellent 10-year conditional survival of 5-year survivors. Additional individual data are needed to clarify the factors underlying the slight decrease in childhood cancer survival observed in the most deprived areas.

Contacts with health services during the year prior to suicide death in France (2013-2015)

Background

This study was designed to describe contacts with health services during the year before suicide death in France, and to compare the prevalent mental and physical conditions in these people to those of the general population.

Methods

Data were extracted from the French National Health Data System (SNDS), which comprises comprehensive claims data for inpatient and outpatient care linked to the national causes-of-death registry. Individuals, national health insurance general scheme beneficiaries (i.e. 76% of the population living in France), aged 15 years or older, who died from suicide in France in 2013-2015 were included. Medical consultations, emergency room visits, and hospitalisations during the year preceding death were collected. Conditions were identified, and standardised prevalence ratios (SPRs) were estimated to compare prevalence rates in suicide decedents with those of the general population.

Results

The study included 19,144 suicide decedents. Overall, 8.5% of suicide decedents consulted a physician or attended an emergency room on the day of death, 34.1% during the week before death, 60.9% during the month before death. Most contacts involved a general practitioner or an emergency room (46.2% of suicide decedents consulted a general practitioner during the month before death, 16.7% attended an emergency room). During the month preceding suicide, 24.4% of individuals were hospitalised at least once. Mental conditions (36.8% of cases) were 7.9-fold (SPR 95% CI: 7.7-8.1) more prevalent in suicide decedents than in the general population. The highest SPRs among physical conditions were for liver/pancreatic diseases (SPR=3.3, 95% CI: 3.1-3.6) and epilepsy (SPR=2.7, 95% CI: 2.4-3.0).

Conclusions

General practitioners and emergency departments have frequent contacts with suicide decedents during the last weeks before death and are at the forefront of suicide risk identification and prevention in individuals with mental, but also physical conditions.

Key messages

Mental and physical conditions are more common among suicide decedents than in the general population, and contacts with primary care services are frequent in the last weeks prior to suicide. Primary care services (general practitioners and emergency rooms) should be targeted for suicide preventive interventions.

Contacts with Health Services During the Year Prior to Suicide Death and Prevalent Conditions A Nationwide Study

BACKGROUND

This study was designed to describe contacts with health services during the year before suicide death in France, and prevalent mental and physical conditions.

METHODS

Data were extracted from the French National Health Data System (SNDS), which comprises comprehensive claims data for inpatient and outpatient care linked to the national causes-of-death registry. Individuals aged ≥15 years who died from suicide in France in 2013-2015 were included. Medical consultations, emergency room visits, and hospitalisations during the year preceding death were collected. Conditions were identified, and standardised prevalence ratios (SPRs) were estimated to compare prevalence rates in suicide decedents with those of the general population.

RESULTS

The study included 19,144 individuals. Overall, 8.5% of suicide decedents consulted a physician or attended an emergency room on the day of death, 34.1% during the week before death, 60.9% during the month before death. Most contacts involved a general practitioner or an emergency room. During the month preceding suicide, 24.4% of individuals were hospitalised at least once. Mental conditions (36.8% of cases) were 7.9-fold more prevalent in suicide decedents than in the general population. The highest SPRs among physical conditions were for liver/pancreatic diseases (SPR=3.3) and epilepsy (SPR=2.7).

LIMITATIONS

The study population was restricted to national health insurance general scheme beneficiaries (76% of the population living in France).

CONCLUSIONS

Suicide decedents have frequent contacts with general practitioners and emergency departments during the last weeks before death. Improving suicide risk identification and prevention in these somatic healthcare settings is needed.

Use of hospital palliative care according to the place of death and disease one year before death in 2013: a French national observational study

Background

Only limited data are available concerning the diseases managed before death and hospital palliative care (HPC) use according to place of death in France. We therefore conducted an observational study based on administrative health data in a large population to identify the diseases treated one year before death in 2013, the place of stay with or without hospital palliative care, and the place of death.

Methods

French health insurance general scheme beneficiaries were identified in the National Health data Information System (Snds) with a selection of information. Diseases were identified by algorithms from reimbursement data recorded in the Snds database.

Results

347,253 people were included in this study (61% of all people who died in France). Place of death was short stay hospital for 51%, Rehab (7%), hospital at home (3%), skilled nursing home (13%) and other (26%). Chronic diseases managed in 2013 before death were cardiovascular/neurovascular diseases (56%), cancers (42%), and neurological and degenerative diseases (25%). During the year before death, 84% of people were hospitalized at least once, and 29% had received HPC. HPC was used by 52% of cancer patients (lung cancer: 62%; prostate cancer: 41%). In the absence of cancer, the use of HPC varied according to the disease: acute stroke: 24%, heart failure: 17%, dementia: 17%, multiple sclerosis: 23%.

Conclusions

Health administrative data can refine the knowledge of the care pathway prior to death and the HPC utilisation and can be useful to evaluate heath policies and improve monitoring and assessment of HPC use.

Use of Procalcitonin Assays to Predict Serious Bacterial Infection in Young Febrile Infants

IMPORTANCE

The procalcitonin (PCT) assay is an accurate screening test for identifying invasive bacterial infection (IBI); however, data on the PCT assay in very young infants are insufficient.

OBJECTIVE

To assess the diagnostic characteristics of the PCT assay for detecting serious bacterial infection (SBI) and IBI in febrile infants aged 7 to 91 days.

DESIGN, SETTING, AND PARTICIPANTS

A prospective cohort study that included infants aged 7 to 91 days admitted for fever to 15 French pediatric emergency departments was conducted for a period of 30 months (October 1, 2008, through March 31, 2011). The data management and analysis were performed from October 1, 2011, through October 31, 2014.

MAIN OUTCOMES AND MEASURES

The diagnostic characteristics of the PCT assay, C-reactive protein (CRP) concentration, white blood cell (WBC) count, and absolute neutrophil cell (ANC) count for detecting SBI and IBI were described and compared for the overall population and subgroups of infants according to the age and the duration of fever. Laboratory test cutoff values were calculated based on receiver operating characteristic (ROC) curve analysis. The SBIs were defined as a pathogenic bacteria in positive culture of blood, cerebrospinal fluid, urine, or stool samples, including bacteremia and bacterial meningitis classified as IBIs.

RESULTS

Among the 2047 infants included, 139 (6.8%) were diagnosed as having an SBI and 21 (1.0%) as having an IBI (11.0% and 1.7% of those with blood culture (n = 1258), respectively). The PCT assay offered an area under the curve (AUC) of ROC curve similar to that for CRP concentration for the detection of SBI (AUC, 0.81; 95% CI, 0.75-0.86; vs AUC, 0.80; 95% CI, 0.75-0.85; P = .70). The AUC ROC curve for the detection of IBI for the PCT assay was significantly higher than that for the CRP concentration (AUC, 0.91; 95% CI, 0.83-0.99; vs AUC, 0.77; 95% CI, 0.65-0.89; P = .002). Using a cutoff value of 0.3 ng/mL for PCT and 20 mg/L for CRP, negative likelihood ratios were 0.3 (95% CI, 0.2-0.5) for identifying SBI and 0.1 (95% CI, 0.03-0.4) and 0.3 (95% CI, 0.2-0.7) for identifying IBI, respectively. Similar results were obtained for the subgroup of infants younger than 1 month and for those with fever lasting less than 6 hours.

CONCLUSIONS AND RELEVANCE

The PCT assay has better diagnostic accuracy than CRP measurement for detecting IBI; the 2 tests perform similarly for identifying SBI in febrile infants aged 7 to 91 days.

Stability of procalcitonin at room temperature

BACKGROUND

The aim was to assess procalcitonin (PCT) stability after two days of storage at room temperature.

METHODS

Samples were collected from febrile children aged 7 to 92 days and were rapidly frozen after sampling. PCT levels were measured twice after thawing: immediately (named y) and 48 hours later after storage at room temperature (named x). PCT values were described with medians and interquartile ranges or by categorizing them into classes with thresholds 0.25, 0.5, and 2 ng/mL. The relationship between x and y PCT levels was analyzed using fractional polynomials in order to predict the PCT value immediately after thawing (named y') from x.

RESULTS

A significant decrease in PCT values was observed after 48 hours of storage at room temperature, either in median, 30% lowering (p < 0.001), or as categorical variable (p < 0.001). The relationship between x and y can be accurately modeled with a simple linear model: y = 1.37 x (R2 = 0.99). The median of the predicted PCT values y' was quantitatively very close to the median of y and the distributions of y and y' across categories were very similar and not statistically different.

CONCLUSIONS

PCT levels noticeably decrease after 48 hours of storage at room temperature. It is possible to pre- dict accurately effective PCT values from the values after 48 hours of storage at room temperature with a simple statistical model.
