Screening for Vulnerability in Older Cancer Patients: The ONCODAGE Prospective Multicenter Cohort Study:
Background: Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13). Patients and Methods: The diagnostic accuracy of the G8 and the (VES-13) were evaluated in a prospective cohort study of 1674 cancer patients accrued before treatment in 23 health care facilities. 1435 were eligible and evaluable. Outcome measures were multidimensional geriatric assessment (MGA), sensitivity (primary), specificity, negative and positive predictive values and likelihood ratios of the G8 and VES-13, and predictive factors of 1-year survival rate. Results: Patient median age was 78.2 years (70-98) with a majority of females (69.8%), various types of cancer including 53.9% breast, and 75.8% Performance Status 0-1. Impaired MGA, G8, and VES-13 were 80.2%, 68.4%, and 60.2%, respectively. Mean time to complete G8 or VES-13 was about five minutes. Reproducibility of the two questionnaires was good. G8 appeared more sensitive (76.5% versus 68.7%, P5 0.0046) whereas VES-13 was more specific (74.3% versus 64.4%, P<0.0001). Abnormal G8 score (HR = 2.72), advanced stage (HR = 3.30), male sex (HR = 2.69) and poor Performance Status (HR = 3.28) were independent prognostic factors of 1-year survival. Conclusion: With good sensitivity and independent prognostic value on 1-year survival, the G8 questionnaire is currently one of the best screening tools available to identify older cancer patients requiring geriatric assessment, and we believe it should be implemented broadly in daily practice. Continuous research efforts should be pursued to refine the selection process of older cancer patients before potentially life-threatening therapy
Functional mechanisms underlying pleiotropic risk alleles at the 19p13.1 breast-ovarian cancer susceptibility locus
A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10-20), ER-negative BC (P=1.1 × 10-13), BRCA1-associated BC (P=7.7 × 10-16) and triple negative BC (P-diff=2 × 10-5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10-3) and ABHD8 (P<2 × 10-3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3′-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk

Age impacts the pattern of care for elderly patients with rectal cancer
Purpose This study analyzed the current approaches for rectal cancer treatment in elderly patients. Methods We retrospectively studied 240 rectal cancer patients who had undergone radiotherapy from 2000 to 2008. The ages of the patients ranged from 65 and 75 years (group A, n = 127) and older than 75 years (group B, n = 113). The distribution of the Charlson comorbidity index was similar between the two groups, but the ECOG performance status (PS) differed between the groups (66 % of the patients of group A were PS 0, and 40% were PS 0 in group B(p < 0.0001)). The tumor stages were comparable between groups. Results The median age of the patients was 74.3 years (range 65-90.6). Treatment was discussed during a multidisciplinary cancer team meeting before treatment for 55 % of the cases in group A and 73 % of the cases in group B (p < 0.001), and treatment proposals were in accordance with guidelines in 96 % of the cases in group A and 76 % of the cases in group B (p < 0.001). Group B patients received slightly less concurrent chemotherapy (35 vs. 30 % for group A; p = 0.54), more hypofractionated radiotherapy (41 vs. 54 % for group A; p = 0.064), less surgery (92 vs. 80 % for group A; p = 0.014), and less adjuvant chemotherapy (34 vs. 10 % for group A; p < 0.001). Finally, 80 % of the patients in group A and 60 % of the patients in group B received treatment in accordance with guidelines (p = 0.007) and in the logistic regression model. Non-metastatic patients who were aged below 75 years were predicted for conformal management (HR=0.323; 95 % CI=0.152-0.684) irrespective of their performance status, comorbidity, or disease stage. Conclusions Treatment proposals and administered therapy differed according to age
