Surgery in the elderly: the role of nutritional support

Surgical oncology in the elderly

Poor cancer-specific outcomes in the elderly group are primarily a surgical failure. Surgeons are insufficiently trained to draw a line between fit and frail patients; this results in over-treatment of the frail patient, as well as under-treatment of the fit one. Communication skills should be improved to better understand the patient's requests. The timing of the surgical procedure is crucially important; all efforts should be put in place to optimize the patient's conditions before the surgery takes place.

Surgery for colorectal cancer in elderly: a comparative analysis of risk factor in elective and urgency surgery

INTRODUCTION

Colon cancer therapy is primarily surgical. Advanced age does not represent a contraindication to surgery. We analyse the results of surgery in ultra 75 patients undergoing surgery for colorectal cancer by examining the correlation between the comorbidity and any post-operative complications.

MATERIALS AND METHODS

We surgically treated 66 patients for colorectal cancer, aged over 75. The examined subjects were compromised for various reasons. We have evaluated the different influences of risk factors in elective and urgency operation.

DISCUSSION

Several studies have shown that age alone is not a significant prognostic factor in survival after colonic surgery. The assessment of general conditions in elderly patients, as demonstrated by the literature, is a fundamental moment in the management of colorectal cancer.

CONCLUSIONS

The surgical choice should be made case by case (custom-made), not based on age only.

Poor nutritional status is associated with other geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients - A multicentre cohort study

BACKGROUND

Nutritional status (NS), though frequently affected in onco-geriatric patients, is no standard part of a geriatric assessment. The aim of this study was to analyse the association between a preoperatively impaired NS and geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients.

METHODS

309 patients ≥70 years undergoing surgery for solid tumours were prospectively recruited. Nine screening tools were preoperatively administered as part of a geriatric assessment. NS was based on BMI, weight loss and food intake. Odds ratio's (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression analysis. The occurrence of 30-day adverse postoperative outcomes was recorded.

RESULTS

At a median age of 76 years, 107 patients (34.6%) had an impaired NS. Decreased performance status and depression were associated with an impaired NS, when adjusted for tumour characteristics and comorbidities (ORPS>1 3.46; 95% CI 1.56-7.67. ORGDS>5 2.11; 95% CI 1.05-4.26). An impaired NS was an independent predictor for major complications (OR 3.3; 95% CI 1.6-6.8). Ten out of 11 patients who deceased had an impaired NS.

CONCLUSION

An impaired NS is prevalent in onco-geriatric patients considered to be fit for surgery. It is associated with decreased performance status and depression. An impaired NS is a predictor for adverse postoperative outcomes. NS should be incorporated in a geriatric assessment.

Treatment of colorectal cancer in older patients: International Society of Geriatric Oncology (SIOG) consensus recommendations 2013

Colorectal cancer (CRC) is one of the most commonly diagnosed cancers in Europe and worldwide, with the peak incidence in patients >70 years of age. However, as the treatment algorithms for the treatment of patients with CRC become ever more complex, it is clear that a significant percentage of older CRC patients (>70 years) are being less than optimally treated. This document provides a summary of an International Society of Geriatric Oncology (SIOG) task force meeting convened in Paris in 2013 to update the existing expert recommendations for the treatment of older (geriatric) CRC patients published in 2009 and includes overviews of the recent data on epidemiology, geriatric assessment as it relates to surgery and oncology, and the ability of older CRC patients to tolerate surgery, adjuvant chemotherapy, treatment of their metastatic disease including palliative chemotherapy with and without the use of the biologics, and finally the use of adjuvant and palliative radiotherapy in the treatment of older rectal cancer patients. An overview of each area was presented by one of the task force experts and comments invited from other task force members.

Preoperative preparation of geriatric patients

There is a continuous increase in the proportion of elderly patients undergoing surgical procedures. This review will concentrate on selected topics related to elderly care that represent current unresolved and relevant issues for the care of the elderly surgical patient including: aging related organ dysfunction, perioperative risk assessment of geriatrics patient, preoperative optimization and pharmacological support of elderly patient. Additionally, age as a clear risk factor for postoperative cognitive dysfunction is also discussed.

Surgical risk and post-operative complications in older unfit cancer patients

Surgeons have always dealt with elderly cancer patients, but understanding frailty and tailoring treatment is a new achievement endeavour. Mounting evidence is resulting in the introduction of geriatric assessment into clinical practice. Particularly, undernourishment should be assessed and corrected in order to avoid emergency situations whenever possible.

[Acute orthogeriatric care (II). Clinical aspects]

The present article reviews the clinical principles of acute orthogeriatric care. The application of geriatric medicine to patients with hip fracture is explained. The principal stages of geriatric intervention in this process are mentioned, as are the interventions to be carried out by the geriatric team. Subsequently, we discuss the management of several frequent problems in these patients, such as high surgical risk, pain management, anaemia, delirium, malnutrition, and discharge planning. Lastly, the characteristics of several kinds of patients with special characteristics are mentioned, such as those diagnosed with dementia, nursing home residents or the oldest-old. Areas of improvement in the acute phase are also reviewed, such as mortality reduction, functional outcome improvement and the need for more efficient resource use in patients in the acute phase of hip fracture.

Short-term mortality after perforated or bleeding peptic ulcer among elderly patients: a population-based cohort study

Background

Mortality after perforated and bleeding peptic ulcer increases with age. Limited data exist on how the higher burden of comorbidity among elderly patients affects this association. We aimed to examine the association of age with short-term mortality after perforated and bleeding peptic ulcer and to determine the impact of comorbidity on this association.

Methods

In this population-based cohort study in three Danish counties between 1991 and 2003 we identified two cohorts of patients: those hospitalized with a first-time discharge diagnosis of perforated peptic ulcer and those with bleeding peptic ulcer. The diagnoses were ascertained from hospital discharge registries and mortality through the Danish Civil Registration System. Information on comorbidity and use of ulcer-related drugs was obtained through administrative medical databases. We computed age-, gender- and comorbidity-standardized 30-day mortality rates and used Cox's regression to estimate adjusted 30-day mortality rate ratios (MRR) for elderly compared with younger patients.

Results

Among 2,061 patients with perforated peptic ulcer, 743 (36%) were 65–79 years old and 513 patients (25%) were aged 80+ years. Standardized 30-day mortality was 8.9% among patients younger than 65 years rising to 44.6% among patients aged 80+ years, corresponding to an adjusted MRR of 5.3 (95% CI: 4.0–7.0). Among 7,232 patients with bleeding peptic ulcer 2,372 (33%) were aged 80+ years. Standardized 30-day mortality among patients younger than 65 was 4.3% compared with 16.9% among patients aged 80+ years, corresponding to an adjusted MRR of 3.7 (95% CI: 2.9–4.7). Analyses stratified by comorbidity consistently showed high MRRs among elderly patients, regardless of comorbidity level.

Conclusion

Ageing is a strong predictor for a poor outcome after perforated and bleeding peptic ulcer independently of comorbidity.

Preoperative Assessment of Surgical Risk in Oncogeriatric Patients

Cancer is a prevalent disease in our aging population; however, few oncologists are familiar with caring for oncogeriatric patients. Surgery is presently the treatment of choice for most solid tumors, but it is frequently delivered in a suboptimal way in this patient subsetting. Undertreatment is often justified with the concern of an unsustainable toxicity, while overtreatment can be related to the lack of knowledge in optimizing preoperative risk assessment. To draw new light on this issue, several surgeons presented their series, providing hard evidence that surgical options can be offered to the elderly with cancer, with only a limited postoperative mortality and morbidity. As it is likely that much of these data suffer from selection bias, we concentrated on Comprehensive Geriatric Assessment (CGA), which can add substantial information on the functional assessment of elderly cancer patients. A validated instrument such as the CGA allows a comparison of series, predicting short-term surgical outcomes more precisely, and offers appropriate information when consenting elderly patients. Preoperative Assessment of Cancer in the Elderly is a prospective international study conceived and launched to outline the fitness of elderly surgical patients with malignant tumors. This paper reports on preliminary results and analysis from the ongoing study.

A comparison of energy intake between eating positions in a NHS hospital—a pilot study

Malnutrition and the under-consumption of food in hospitals is prevalent and in UK hospitals, the consumption of meals is mainly a solitude event, despite evidence to show that eating in the presence of others can actually increase food intake. Dietary data were collected for three consecutive 24 h periods (n=13) from patients who consumed their meals either in bed, at the side of the bed or in the presence of others. Results show a significant increase (p<0.05) in the mean daily energy intake for those sitting around a table in the presence of others. Although a small pilot study, the results confirm the value of social facilitation in improving the under-consumption of food when in hospital.

The surgical management of elderly cancer patients

Although cancer in the elderly is extremely common, few health professionals in oncology are familiar with caring for series of oncogeriatric patients. Surgery is at present the first choice, but is frequently delivered suboptimally: under-treatment is justified by concerns about unsustainable toxicity, whilst over-treatment is explained by the lack of knowledge in optimising preoperative risk assessment. This article summarises the point of view of the Surgical Task Force @ SIOG (International Society for Geriatric Oncology), pointing out differences from, and similarities to, the younger cohorts of cancer patients, and highlighting the latest updates and trends specifically related to senior cancer patients.

Nutritional issues in the care of the elderly patient

Aging is associated with a progressive decline in the function of many organs and apparatus. In a medical context, depletion of lean body mass and muscle mass in particular, and alteration of the immune system are of utmost importance. A defective immune response is associated with an increased incidence of inflammatory, infective and neoplastic diseases in the elderly as well as with a slow and sluggish recovery after illness or other injury. Depletion of muscle mass, the so-called sarcopenia, is responsible for the typical frailty of the elderly. Moreover, since muscle represents the protein reserve of the body, its progressive erosion not only results in a poor mobility and disability of these subjects, with associated complications, but with a diminished capacity to meet the extra demand of protein synthesis associated with disease and injury. In cancer patients, as in other elderly patients with different pathologies, it is important to evaluate the nutritional status, since frailty of these individuals recognizes as a relevant etiopathogenetic cofactor, a defective food intake. Nutritional support should aim at meeting the requirements in macronutrients, in water and in micronutrients. Requirements are not so different from those of adult subjects, since the decrease in energy expenditure due to a lower physical activity is compensated by the increase due to the disease. Particular attention must be given to fluid administration, since the elderly tolerate fluid overload less than hypohydration. Elderly patients quite frequently suffer from long-standing undernutrition; this means that nutritional repletion will take more time than is usually expected with use of medication. If a correct feeding program is performed for a few weeks, a benefit can be observed not only on the nutritional status but also in the clinical outcome. In fact nutritional support may have a permissive role in the administration of aggressive (oncologic) treatment than may be otherwise denied to elderly patients.

Risk of endovascular treatment of brain arteriovenous malformations

BACKGROUND AND PURPOSE

Independently assessed data on frequency, severity, and determinants of neurological deficits after endovascular treatment of brain arteriovenous malformations (AVMs) are scarce.

METHODS

From the prospective Columbia AVM Study Project, 233 consecutive patients with brain AVM receiving > or =1 endovascular treatments were analyzed. Neurological impairment was assessed by a neurologist using the Rankin Scale before and after completed endovascular therapy. Multivariate logistic regression models were used to identify demographic, clinical, and morphological predictors of treatment-related neurological deficits. The analysis included the components used in the Spetzler-Martin risk score for AVM surgery (AVM size, venous drainage pattern, and eloquence of AVM location).

RESULTS

The 233 patients were treated with 545 endovascular procedures. Mean follow-up time was 9.6 months (SD, 18.1 months). Two hundred patients (86%) experienced no change in neurological status after treatment, and 33 patients (14%) showed treatment-related neurological deficits. Of the latter, 5 (2%) had persistent disabling deficits (Rankin score >2), and 2 (1%) died. Increasing patient age [odds ratio (OR), 1.04; 95% confidence interval (CI), 1.01 to 1.08], number of embolizations (OR, 1.41; 95% CI, 1.16 to 1.70), and absence of a pretreatment neurological deficit (OR, 4.55; 95% CI, 1.03 to 20.0) were associated with new neurological deficits. None of the morphological AVM characteristics tested predicted treatment complications.

CONCLUSIONS

From independent neurological assessment and prospective data collection, our findings suggest a low rate of disabling treatment complications in this center for endovascular brain AVM treatment. Risk predictors for endovascular treatment differ from those for AVM surgery.
