Prediction of overall survival in patients with hepatocellular carcinoma treated with Y-90 radioembolization by imaging response criteria

PURPOSE

To evaluate the potential of imaging criteria in predicting overall survival of patients with hepatocellular carcinoma (HCC) after a first transcatheter arterial yttrium-90 radioembolization (TARE) MATERIALS AND METHODS: From October 2013 to July 2017, 37 patients with HCC were retrospectively included. There were 34 men and 3 women with a mean age of 60.5±10.2 (SD) years (range: 32.7-78.9 years). Twenty-five patients (68%) were Barcelona Clinic Liver Cancer (BCLC) C and 12 (32%) were BCLC B. Twenty-four primary index tumors (65%) were>5cm. Three radiologists evaluated tumor response on pre- and 4-7 months post-TARE magnetic resonance imaging or computed tomography examinations, using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, modified RECIST (mRECIST), European Association for Study of the Liver (EASL), volumetric RECIST (vRECIST), quantitative EASL (qEASL) and the Liver Imaging Reporting and Data System treatment response algorithm. Kaplan-Meier survival curves were used to compare responders and non-responders for each criterion. Univariate and multivariate Cox proportional hazard ratio (HR) analysis were used to identify covariates associated with overall survival. Fleiss kappa test was used to assess interobserver agreement.

RESULTS

At multivariate analysis, RECIST 1.1 (HR: 0.26; 95% confidence interval [95% CI]: 0.09-0.75; P=0.01), mRECIST (HR: 0.22; 95% CI: 0.08-0.59; P=0.003), EASL (HR: 0.22; 95% CI: 0.07-0.63; P=0.005), and qEASL (HR: 0.30; 95% CI: 0.12-0.80; P=0.02) showed a significant difference in overall survival between responders and nonresponders. RECIST 1.1 had the highest interobserver reproducibility.

CONCLUSION

RECIST and mRECIST seem to be the best compromise between reproducibility and ability to predict overall survival in patients with HCC treated with TARE.

Trends in hospitalization rates for psoriasis flares since the introduction of biologics: a time series in France between 2005 and 2015

BACKGROUND

In the late 2000s, the introduction of biologics transformed the prognosis for patients with moderate-to-severe psoriasis. We hypothesized that treatment with biologics may associate with a reduction in the hospitalization rate for psoriasis flares.

OBJECTIVE

To analyse changes over time in the hospitalization rate for psoriasis flares.

METHODS

We included inpatient stays in any of nine French hospitals between 2005 and 2015 for a psoriasis flare, as documented in the national inpatient database. In two centres, we also analysed data from the individual patients' electronic medical records.

RESULTS

A total of 3572 stays were included. The introduction of biologics was not associated with a decrease in the number of hospitalizations for a psoriasis flare; on the contrary, we observed a non-significant increase in the number of hospitalizations (13 hospitalizations for psoriasis flares per quarter per 10 000 beds). In the two-centre study, the introduction of biologics was associated with a significant increase in the hospitalization of patients receiving topical treatments only (520 hospitalizations per year per 10 000 beds) and those with a first psoriasis flare.

CONCLUSION

The number of hospitalizations for a psoriasis flare tended to increase between 2005 and 2015. The availability of additional treatment options might have increased patient demand and/or broadened the indications in clinical practice.

Screening for frailty in community-dwelling elderly subjects: Predictive validity of the modified SEGA instrument

AIMS

To study the capacity of the SEGAm instrument to predict loss of independence among elderly community-dwelling subjects.

METHODS

The study was performed in four French departments (Ardennes, Marne, Meurthe-et-Moselle, Meuse). Subjects aged 65 years or more, living at home, who could read and understand French, with a degree of autonomy corresponding to groups 5 or 6 in the AGGIR autonomy evaluation scale were included. Assessment included demographic characteristics, comprehensive geriatric assessment, and the SEGAm instrument at baseline. Subjects had follow-up visits at home at 6 and 12 months. During follow-up, vital status and level of independence were recorded. Logistic regression was used to study predictive validity of the SEGAm instrument.

RESULTS

Among the 116 subjects with complete follow-up, 84 (72.4%) were classed as not very frail at baseline, 23 (19.8%) as frail, and 9 (7.8%) as very frail; 63 (54.3%) suffered loss of at least one ADL or IADL at 12 months. By multivariable analysis, frailty status at baseline was significantly associated with loss of independence during the 12 months of follow-up (OR=4.52, 95% CI=1.40-14.68; p=0.01). We previously validated the SEGAm instrument in terms of feasibility, acceptability, internal structure validity, reliability, and discriminant validity.

CONCLUSIONS

This instrument appears to be a suitable tool for screening frailty among community-dwelling elderly subjects, and could be used as a basis to plan early targeted interventions for subjects at risk of adverse outcome.

Screening for frailty in elderly subjects living at home: validation of the Modified Short Emergency Geriatric Assessment (SEGAm) instrument

OBJECTIVES

To validate the modified version of the Short Emergency Geriatric Assessment (SEGAm) frailty instrument in elderly people living at home.

DESIGN

Longitudinal, prospective, multicentre study.

SETTING

Four departments (Ardennes, Marne, Meurthe-et-Moselle, Meuse) in two French Regions (Champagne-Ardenne and Lorraine).

PARTICIPANTS

Subjects aged 65 years or more, living at home, who could read and understand French, with a degree of autonomy corresponding to groups 5, or 6 in the AGGIR autonomy evaluation scale.

MEASUREMENTS

Assessment included demographic characteristics, comprehensive geriatric assessment, and the SEGAm instrument. Psychometric validation was used to study feasibility and acceptability, internal structure validity, reliability, and discriminant validity of the SEGAm instrument.

RESULTS

Between July 1st 2012 and March 31st 2013, 167 patients were included in the study. Averaged age was 77±7 years, the majority were women (70.7%). Feasibility and acceptability of the SEGAm instrument were excellent: we observed no refusal to participate, no drop-out during administration, no missing items, no ceiling or floor effects, and the administration time was short (5.0±3.5 min). By factor analysis, the instrument proved to be unidimensional. It showed good internal consistency (Cronbach's alpha coefficient: 0.68) and good test-retest (intra-class correlation: 0.88) at 7 days interval. Discriminant validity showed a significant difference, mainly for nutritional status, fall risk, dependency, mood and depression risk, and comorbidities.

CONCLUSION

Based on these psychometric properties, the SEGAm appears to be an easy-to-use instrument that is particularly suitable for use in the community to identify frail elderly people who could benefit from early targeted interventions.
