Vulnerabilities in Older Patients when Cancer Treatment is Initiated: Does a Cognitive Impairment Impact the Two-Year Survival?

INTRODUCTION: Dementia is a known predictor of shorter survival times in older cancer patients. However, no empirical evidence is available to determine how much a cognitive impairment shortens survival in older patients when cancer treatment is initiated. PURPOSE: To longitudinally investigate how much a cognitive impairment detected at the initiation of cancer treatment influences survival of older patients during a two-year follow-up duration and to compare the predictive value of a cognitive impairment on patients survival with the predictive value of other vulnerabilities associated with older age. METHODS: Three hundred and fifty-seven consecutive patients (≥65 years old) admitted for breast, prostate, or colorectal cancer surgeries were prospectively recruited. A cognitive impairment was assessed with the Montreal Cognitive Assessment (MoCA<26). Socio-demographic, disease-related, and geriatric vulnerabilities were assessed using validated tools. Univariate and subsequent multivariate Cox proportional hazards models stratified for diagnosis (breast/prostate cancer versus colorectal cancer) and disease status (metastatic versus non-metastatic) were used. RESULTS: A cognitive impairment was detected in 46% (n = 163) of patients. Survival was significantly influenced by a cognitive impairment (HR = 6.13; 95% confidence interval [CI] = 2.07-18.09; p = 0.001), a loss in instrumental autonomy (IADL ≤7) (HR = 3.06; 95% CI = 1.31-7.11; p = 0.009) and fatigue (Mob-T<5) (HR = 5.98; 95% CI = 2.47-14.44; p <0.001). CONCLUSIONS: During the two years following cancer treatment initiation, older patients with a cognitive impairment were up to six times more likely to die than patients without. Older patients should be screened for cognitive impairments at cancer treatment initiation to enable interventions to reduce morbidity and mortality. Further studies should address processes underlying the relationship between cognitive impairments and an increased risk of dying in older cancer patients.

Cardiac assessment of early breast cancer patients 18 years after treatment with cyclophosphamide-, methotrexate-, fluorouracil- or epirubicin-based chemotherapy.

BACKGROUND: Epirubicin-based chemotherapy improves the outcome of early breast cancer (BC) patients. However, cardiotoxicity remains an important side effect. METHODS: We re-consented node-positive BC patients enrolled in a phase III trial between 1988 and 1996 which compared six cycles of oral cyclophosphamide, methotrexate, fluorouracil (CMF) versus two epirubicin-cyclophosphamide regimens differing by the anthracycline cumulative dose [standard-dose epirubicin and cyclophosphamide (SDE) (8 × 60 mg/m(2)) and higher-dose epirubicin and cyclophosphamide (HDE) (8 × 100 mg/m(2))]. Eligible patients were those who were alive and free of disease and had no contra-indications to the proposed tests (cardiac evaluation). Cardiotoxicity was defined as asymptomatic systolic dysfunction (left ventricular ejection fraction (LVEF)< 50%, New York Heart Association (NYHA) Class I) or symptomatic heart failure (NYHA Class II-IV). Differences in cardiotoxicity between CMF and SDE/HDE were assessed using chi-square and Fisher Exact tests for binary variables and t-test and Wilcoxon test for continuous variables. RESULTS: Among the 777 patients, 20 cases of CHF were reported (CMF = 1, SDE = 5, HDE = 14; p < 0.001). Between September 2010 and June 2013, 82 patients (30%) out of 269 eligible patients accepted to participate in this substudy. Median follow-up was 18 years (range 15-24). Epirubicin-treated patients had significantly higher heart rate, more abnormal echocardiograms and LVEF by magnetic resonance imaging (MRI) compared to CMF-treated ones. A trend towards higher BNP was also observed in the SDE/HDE group (P = 0.08). No differences were observed in LVEF assessed by echocardiogram or troponin T levels. CONCLUSIONS: Participation rate in this substudy was lower than expected highlighting the complexity of re-calling patients several years after the initial BC diagnosis. After 18 years, epirubicin-treated patients had a lower LVEF by MRI, more abnormal echocardiograms, higher heart rates compared to patients treated with CMF. However, no major delayed cardiotoxicity was observed.

Identification of clinical parameters predictive of one-year survival using two geriatric tools in clinically fit older patients with hematological malignancies: Major impact of cognition.

BACKGROUND: Little is known about the reliability of G8 screening tool and the prognostic value of clinical parameters within the Comprehensive Geriatric Assessment (CGA) in clinically fit older patients with hematological malignancies. MATERIALS AND METHODS: This study was performed to assess the reliability of G8 as a screening tool and to determine the predictive value of CGA items in terms of 1-year overall survival (OS). G8 and CGA were proposed to 107 consecutive patients (65-89 years) with hematological malignancies assessed by their physicians as clinically fit, meaning not exhibiting geriatric syndromes and/or irreversible comorbidities significantly impairing their daily function, and thus able to receive chemotherapy. RESULTS: Out of 107 patients, 90 patients were evaluable and completed both scales; 72% and 80% were defined as "vulnerable" when evaluated with G8 (≤ 14.5) or CGA (≥ 2 impairments) respectively. The area under ROC-curve of G8 compared to CGA was 0.749±0.051. Neither G8 nor CGA total scores were predictive of 1-year OS. However, age (HR=1.105, 95% CI: 1.016-1.202; p=0.019), diagnosis (HR=5.208, 95% CI: 1.895-14.310; p=0.001) and cognitive status (HR=3.260, 95% CI: 1.043-10.194; p=0.042) were predictive of OS. CONCLUSIONS: We conclude that in our selected hematological patients: 1) the G8 score does not help selecting patients for CGA, 2) the G8 and CGA total scores do not predict OS, and 3) in addition to the age and disease itself, cognitive impairment appears to be a powerful prognostic factor.

The prevalence and implications of elderly inpatients' desire for a formal psychological help at the start of cancer treatment.

INTRODUCTION: Little is known about elderly cancer inpatients' desire for psychological help. PURPOSE: The aim of this study was to investigate whether elderly cancer inpatients well informed about their diagnosis expressed a desire to receive formal psychological help at the start of their cancer treatment. The characteristics of the patients that sought help were examined. METHODS: This cross-sectional study assessed 650 consecutive cancer inpatients that were 65 years of age and older when they started treatment for breast, colorectal, ovarian, lung, prostate or haematological cancers. Disease-related, medical and psychological characteristics of these patients were assessed using validated tools. RESULTS: Distress and cognitive impairment were experienced by 37% and 46% of elderly cancer inpatients, respectively. However, only 12% of patients reported a desire for formal psychological help (14% of women vs 9% of men). The patient characteristics examined were found to be weakly associated with this desire (this explained 16% of the variance for women and 14% for men). For the female subgroup, this desire was associated with age [<75 years vs ≥75 years; odds ratio (OR) = 2.57], marital status (without a partner vs with a partner; OR = 2.26) and distress (OR = 1.13). For the male subgroup, loss of functional autonomy (OR = 1.41) and pain (OR = 1.22) were relevant characteristics. CONCLUSIONS: Although more than about four out of 10 elderly cancer inpatients in this study experience distress or cognitive impairment, only about one out of 10 expresses a desire for formal psychological help. Therefore, an appropriate sequence of interventions should be scheduled in order to offer them an optimal formal psychological help.
