Development of a geriatric screening tool is necessary to identify elderly cancer patients who would benefit from comprehensive geriatric assessment (CGA). We develop and evaluate the G-8 screening tool against various reference tests. Analyses were based on 364 cancer patients aged >70 years scheduled to receive first-line chemotherapy included in a multicenter prospective study. The G-8 consists of seven items from the Mini Nutritional Assessment (MNA) questionnaire and age. Our primary reference test is based on a set of seven CGA scales: Activities Daily Living (ADL), Instrumental ADL, MNA, Mini–Mental State Exam, Geriatric Depression Scale, Cumulative Illness Rating Scale-Geriatrics, and Timed Get Up and Go. We considered the presence of at least one questionnaire with an impaired score as an abnormal reference exam. Additional reference exams are also discussed. The prevalence of being at risk varied from 60% to 94% according to the various definitions of the reference test. When considering the primary reference test, a cut-off value of 14 for the G-8 tool provided a good sensitivity estimate (85%) without deteriorating the specificity excessively (65%). The G-8 shows good screening properties for identifying elderly cancer patients who could benefit from CGA.

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). 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. 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%, P = 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. 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.

Purpose: Objective factors for making choices about the treatment of elderly patients with cancer are lacking. This investigation aimed to help physicians select appropriate treatments through the identification of factors that predict early death (< 6 months) after initiation of chemotherapy treatment. Patients and Methods: Previously untreated patients greater than 70 years of age who were scheduled for first-line chemotherapy for various types of cancer were included. Baseline abbreviated comprehensive geriatric assessment (aCGA), including the Mini-Mental State Exam, Timed Get Up and Go (GUG), Activities of Daily Living (ADL), Instrumental Activities in Daily Living (IADL), Mini Nutritional Assessment (MNA), Geriatric Depression Scale (GDS15), and comorbidities index (Cumulative Index Rating Scale-Geriatric), was carried out. Prognostic factors of early death were sought from aCGA results and traditional oncology measures. Results: A total of 348 patients were included across 12 centers in Southwest France (median age, 77.45 years; ratio of men to women, 1.47; advanced disease, 65%). Abnormal aCGA scores were observed for 18.1% of patients on the ADL, 73.0% of patients on the IADL, 24.1% of patients on the GUG, 19.0% of patients on the MMS, 44.0% of patients on the GDS15, and 64.9% of patients on the MNA. Advanced disease (odds ratio [OR], 3.9; 95% CI, [1.58 to 9.73]), a low MNA score (OR 2.77; 95% CI, [1.24 to 6.18]), male sex (OR, 2.40; 95% CI, [1.2 to 4.82]), and long GUG (OR, 2.55; 95% CI, [1.32 to 4.94] were associated with higher risk of early death. Conclusion: In patients greater than 70 years of age with cancer, advanced disease, a low MNA score, and poor mobility predicted early death. We recommend that the MNA and GUG, performed by a trained nurse, be maintained as part of routine pretreatment workup in these patients to identify at-risk patients and to inform the decision-making process for chemotherapy.

The Cox model relies on the proportional hazards (PH) assumption, implying that the factors investigated have a constant impact on the hazard - or risk - over time. We emphasize the importance of this assumption and the misleading conclusions that can be inferred if it is violated; this is particularly essential in the presence of long follow-ups.

Purpose To determine factors associated with early functional decline during first-line chemotherapy in older patients. Patients and Methods Patients age ≥ 70 years receiving first-line chemotherapy for cancer were prospectively considered for inclusion across 12 centers in France. Functional decline was defined as a decrease of ≥ 0.5 points on the Activities of Daily Living (ADL) scale between the beginning of chemotherapy and the second cycle. Factors associated with functional decline were sought from pretreatment abbreviated comprehensive geriatric assessment, including ADL, Instrumental ADL (IADL), Mini-Nutritional Assessment (MNA), Mini–Mental State Examination (MMSE), Geriatric Depression Scale (GDS15), and Timed Get Up and Go (GUG) test, and from comorbidities (Cumulative Illness Rating Scale–Geriatrics), MAX2 index, and baseline biologic and clinical information. Results Of 364 included patients, 50 experienced functional decline (16.7%; median, 0.5 points). Abnormal preadmission performance status, IADL, GDS15, MMSE, GUG, and MNA were associated with increased likelihood of functional decline (univariate analysis). In the multivariate model adjusted for baseline ADL and MAX2 index, high baseline GDS (odds ratio [OR], 2.16; 95% CI, 1.09 to 4.30; P = .03) and low IADL scores (OR, 2.87; 95% CI, 1.06 to 7.79; P = .04) were independently associated with increased risk of functional decline. Conclusion Our results outline associations between baseline depression, instrumental dependencies, and early functional decline during chemotherapy for older patients. ADL should be sequentially evaluated early during treatment. Baseline evaluation of GDS15 and IADL may be proposed to anticipate this event.

Well-designed observational studies of individuals with rare tumors are needed to improve patient care, clinical investigations, and the education of healthcare professionals. The patterns of care, outcomes, and prognostic factors of a cohort of 2225 patients with metastatic soft tissue sarcomas who were diagnosed between 1990 and 2013 and documented in the prospectively maintained database of the French Sarcoma Group were analyzed. The median number of systemic treatments was 3 (range, 1–6); 27% of the patients did not receive any systemic treatment and 1054 (49%) patients underwent locoregional treatment of the metastasis. Half of the patients who underwent chemotherapy (n = 810) received an off-label drug. Leiomyosarcoma was associated with a significantly better outcome than the other histological subtypes. With the exception of leiomyosarcomas, the benefit of a greater than third-line regimen was very limited, with a median time to next treatment (TNT) and overall survival (OS) ranging between 2.3 and 3.7 months and 5.4 and 8.5 months, respectively. The TNT was highly correlated with OS. Female sex, leiomyosarcoma histology, locoregional treatment of metastases, inclusion in a clinical trial, and treatment with first-line polychemotherapy were significantly associated with improved OS in the multivariate analysis. The combination of doxorubicin with a second drug, such as ifosfamide, represents a valid option, particularly when tumor shrinkage is expected to provide clinical benefits. After failure of the second-line therapy, best supportive care should be considered, particularly in patients with non-leiomyosarcoma histology who are not eligible to participate in a clinical trial. Locoregional treatment of metastasis should always be included in the therapeutic strategy when feasible. TNT may represent a useful surrogate endpoint for OS in clinical studies.
