Comprehensive geriatric assessment in older adults with cancer: Recommendations by the Italian Society of Geriatrics and Gerontology (SIGG).

INTRODUCTION: Optimizing the approach to older adults with cancer is now a priority given the increasing frequency of new cancer diagnoses that are made in the older population. The comprehensive geriatric assessment (CGA) represents the gold-standard for (1) defining prognosis and ability to withstand cancer treatments, (2) exploring the multiple aspects that define the complexity of frail older persons, and (3) designing person-tailored interventions. MATERIALS AND METHODS: In this document, based on a comprehensive revision of the literature, the Italian Society for Geriatrics and Gerontology proposes a CGA model (ONCOGER CGA) to be adopted by oncology centers for their routine approach to older patients with cancer. RESULTS AND DISCUSSION: A widespread use of this standardized CGA format will facilitate comparisons across institutions, promote studies based on a multidimensional patient assessment, and foster the inclusion of geriatric endpoints in oncological clinical trials. Furthermore, we predict that the use of a standardized CGA approach will increase the integration of geriatricians into oncology care teams with the final result of improving therapeutic choices and clinical outcomes.

The Frailty Index in older women with gynecological cancer.

INTRODUCTION: Frailty is a key condition to be screened among elderly oncological patients. Aim of our work is to measure the functional and prognostic value for 1-year mortality of the Frailty Index (FI) in a cohort of older women with gynecological cancer. METHODS: The prognostic value of FI was tested in 200 older women with gynaecological cancer (mean age = 73.5 years). FI was retrospectively calculated following the Rockwood model. Spearman's rho test was used for correlations with other oncological scales: Eastern Cooperative Oncology Group Performance Status (ECOG); Karnofsky Performance Status (KPS); Vulnerable Elders Scale-13 (VES-13). Cox proportional hazard models and ROC curve were performed to estimate prognostic role of 1-year mortality. Sensitivity and specificity were also calculated. RESULTS: FI is normally distributed and descriptive statistics define our population as frail (mean = 0.25±0.11, range 0.08-0.51). 0.7 is confirmed as an upper limit compatible with life. FI does not significantly correlates with age, ECOG and KPS while it positively correlates with VES-13 (r = 0.7, p < 0.01). FI is the strongest predictor for 1-year mortality confirmed after all adjustments for confounders (OR 3.40; 95% CI 1.55-7.45, p < 0.01) and by ROC curve analyses (0.66, 95% CI 0.51-0.81, p = 0.01). CONCLUSIONS: Frailty Index is a useful tool to detect vulnerability in onco-geriatrics and it predicts 1-year mortality. Further studies are needed to confirm and extend these findings.

Sarcopenia (and sarcopenic obesity) in older patients with gynecological malignancies.

Cancer is often complicated by the deterioration of both muscle mass and function, which may be more pronounced in older people. The prevalence of sarcopenia varies according to tumour type, stage and sarcopenia definition; in gynaecologic malignancies it ranges from 25 to 50%. Unfortunately, sarcopenia is often underdiagnosed especially in overweight and obese patients. The consequences of sarcopenia are serious: shorter time of tumour progression, increased chemotherapy-related toxicity, post-operative complications, poor functional status, hospitalisation, increased length of hospital stay, high 30-day readmission rate and mortality. Therefore, its precocious recognition and treatment is of paramount importance. We demonstrated that obesity can mask sarcopenia, taking into consideration a sample of older patient with cancer, unless body composition evaluation and comprehensive geriatric assessment, including measures of muscle strength and performance, is executed. Our work underlines the importance of a multidisciplinary approach to older patients with cancer to optimize their management.

The E point: a new echographic great saphenous identification sign in specific anatomical variants and applications.

Objective To describe a new ultrasound marker of the Great Saphenous Vein at the groin. Method An ultrasound marker of the Great Saphenous Vein was identified as follows: the Great Saphenous Vein was tracked in cross-sectionally starting from the Sapheno Femoral Junction and optimally visualized where it crosses the Adductor Longus muscle, i.e., 3-5 cm below the junction. This marker, corresponding to a very superficial position of Great Saphenous Vein, was named "E Point," where E means easy to find. The search for the E point was performed on 230 limbs of 126 subjects with or without chronic venous insufficiency (training population) and the method was validated in 58 subjects (testing population). Results The E point was successfully recorded in 128/144 (89%) pathologic and in 85/86 (99%) healthy limbs. Being free from other structures, at the E point the Great Saphenous Vein was always easily calibrated. In 17 cases, the E point could not be identified due to an hypoplasic Great Saphenous Vein; in such instances, the Anterior Accessory Saphenous Vein was well evident and substituted for the Great Saphenous Vein as the main draining vein at the groin. Conclusion The E point identifies the Great Saphenous Vein in healthy and varicose patients. Failure to identify the E point indicates Anterior Accessory Saphenous Vein dominance over a hypoplasic Great Saphenous Vein.

EEG correlates of social interaction at distance.

This study investigated EEG correlates of social interaction at distance between twenty-five pairs of participants who were not connected by any traditional channels of communication. Each session involved the application of 128 stimulations separated by intervals of random duration ranging from 4 to 6 seconds. One of the pair received a one-second stimulation from a light signal produced by an arrangement of red LEDs, and a simultaneous 500 Hz sinusoidal audio signal of the same length. The other member of the pair sat in an isolated sound-proof room, such that any sensory interaction between the pair was impossible. An analysis of the Event-Related Potentials associated with sensory stimulation using traditional averaging methods showed a distinct peak at approximately 300 ms, but only in the EEG activity of subjects who were directly stimulated. However, when a new algorithm was applied to the EEG activity based on the correlation between signals from all active electrodes, a weak but robust response was also detected in the EEG activity of the passive member of the pair, particularly within 9 - 10 Hz in the Alpha range. Using the Bootstrap method and the Monte Carlo emulation, this signal was found to be statistically significant.

Physical function and perceived quality of life in older persons.

BACKGROUND AND AIMS: Physical function and quality of life represent two major components of multidimensional evaluation in older people. The aim of the study was to verify which specific physical function measure is a more important predictor of quality of life in these individuals. METHODS: Data are from 73 community-dwelling older persons attending a geriatric cardiovascular clinic. Linear regressions and analyses of covariance were performed to explore the relationships between physical function measures (4-meter walking test [4mWS], Short Physical Performance Battery [SPPB], Activities of Daily Living [ADL], and Instrumental ADL [IADL]) and quality of life (assessed using the European Quality of Life [EuroQoL] instrument). To provide fair comparisons across all the physical function measures, results were provided according to their increase in standard deviation (SD). RESULTS: The mean age of the sample population (women 52%) was 77.6 (SD=8.3) years old. Given significant gender interactions between physical function and quality of life, separate analyses were conducted for men and women. In women, all physical function measures were significantly associated with quality of life measures in unadjusted models (p-values<0.05). The EuroQoL visual analogic scale maintained its significant associations with SPPB, ADL and IADL, even after adjustment for potential confounders. In men, no physical function measure was consistently associated with quality of life in the fully-adjusted models. Gender-specific differences in the perception of quality of life were reported for disabilities in specific IADL tasks. CONCLUSIONS: Physical function is associated with quality of life in older persons. In particular, disabilities in some specific IADL tasks seem to be especially perceived by women as undermining their quality of life. The use of the IADL scale in men may not be as reliable as in women.

Onco-geriatric approach for the management of older patients with cancer.

INTRODUCTION AND RATIONALE: The number of older cancer patients is increasing with global aging of the population. A close interaction between oncologists and geriatricians becomes necessary to (1) better evaluate the elders' health status, (2) determine their residual clinical/biological reserves, and (3) optimize the provided medical care. In fact, aggressive antineoplastic managements are often denied to older patients, possibly because of the common misconception suggesting older age and/or clinical complexity as absolute contraindications to advanced treatments. METHODS: The primary aim of the presented project is to assess whether assigning a geriatrician to provide daily medical care to older cancer patients (aged 65 years and older) admitted to an oncology ward increases the number of patients eligible for a chemotherapeutic and/or surgical intervention. The project is articulated in 2 phases: (1) a retrospective phase based on analysis of data collected over the 2 years before the beginning of the study, and (2) a prospective 2-year intervention. Additional information about clinical conditions, biological parameters, adverse drug reactions, body composition, physical function, and 1-year health-related events will also be recorded. OUTCOMES: The combination of expertise from oncologists and geriatricians is likely to result in (1) an improved selection of candidates for interventions aimed at increasing disability-free life expectancy and/or overall survival, and (2) a more rational exclusion of patients at higher risk of toxicity or with poor prognosis. In this article, the development of an onco-geriatric unit aimed at the evaluation, management, and treatment of older women with gynecological cancer is also described.

The aging process and potential interventions to extend life expectancy.

Aging is commonly defined as the accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death. The major theories of aging are all specific of a particular cause of aging, providing useful and important insights for the understanding of age-related physiological changes. However, a global view of them is needed when debating of a process which is still obscure in some of its aspects. In this context, the search for a single cause of aging has recently been replaced by the view of aging as an extremely complex, multifactorial process. Therefore, the different theories of aging should not be considered as mutually exclusive, but complementary of others in the explanation of some or all the features of the normal aging process. To date, no convincing evidence showing the administration of existing "anti-aging" remedies can slow aging or increase longevity in humans is available. Nevertheless, several studies on animal models have shown that aging rates and life expectancy can be modified. The present review provides an overlook of the most commonly accepted theories of aging, providing current evidence of those interventions aimed at modifying the aging process.
