Anemia in the elderly-clinical findings and impact on health.

Anemia is common in older people and it becomes more so with advancing decades. Because the older population is increasing, the prevalence of anemia and consequently its impact on health and healthcare expenditure is expected to rise. Although the causes and consequences of anemia have not been fully elucidated and its etiology is occasionally elusive, clinical evidence has indicated that anemia itself is a cause of morbidity and it can complicate other health conditions. The clinical approach to anemia is evolving. In the past, anemia was mainly seen as a sign of underlying disease; today, anemia is considered to be a cause of severe deterioration of quality of life, morbidity, and decline in physical function, and a risk factor for death. A better understanding of anemia in the elderly will lead to improved treatment strategies, including the more judicious use of transfusion and appropriate use of erythropoietic agents.

Predictors of tolerance to chemotherapy in older cancer patients: a prospective pilot study.

Few data are available to help predict which older cancer patient is at risk of developing chemotherapy-related toxicity. This study was a pilot for a project designing a predictive risk score. Chemotherapy patients aged 70 years and older were prospectively enrolled. Chemotherapies were adjusted for their published toxicity. 60 patients were enrolled, 59 were evaluable. Mean dose-intensity was 90.3%, range 33.3-129.0%. 47% of the patients experienced grade 4 haematological and/or grade 3-4 non-haematological toxicity. Published toxicity (MAX2), diastolic blood pressure, marrow invasion and lactate dehydrogenase (LDH) were all associated with toxicity (P<0.1); Body Mass Index, previous chemotherapy, red blood cells, platelets, polymedication with dose-intensity; and polymedication with FACT-G change. After adjustment for the published toxicity, the variables retained their significance, except for LDH and polymedication (for dose-intensity). Although the size of this pilot study imposes a cautious interpretation, patient-related and chemotherapy-related variables correlated independently with toxicity. Designing a composite predictive score to use in assessing the toxicity of multiple chemotherapy regimens therefore appears to be a valid undertaking.

Cancer and age in the USA.

Cancer in the older person has become an increasingly common problem with the aging of the population. The goal of this paper is to review the influence of age on cancer biology and cancer management. Specific interactions of cancer and aging include: Increased incidence of cancer with the age: This association may be reported to three factors: duration of carcinogenesis; increased susceptibility of older tissues to late stage carcinogens, and systemic effects of aging, including immune-senescence and enhanced cytokine production. Biological behavior of cancer: With aging, the prognosis of certain neoplasms, including acute myelogenous leukemia and large-cell non-Hodgkin's lymphoma worsens, whereas the behavior of other tumors becomes more indolent. In these biologic variations one may recognize both a 'seed" effect (different tumor cells) and a "soil" effect (different ways in which the older tumor host handles tumor growth. Goals of prevention and treatment: Given the limited life-expectancy of older individuals and reduced tolerance of clinical intervention, the main goal is compression of morbidity, rather than prolongation of survival. Cancer prevention in the older person: In virtue of increased susceptibility to environmental carcinogens, the older person appears an ideal candidate for primary prevention of cancer, including chemoprevention; though randomized controlled studies have not been performed, the older person may benefit from secondary prevention (screening), when the average life-expectancy is 3 years or longer. Cancer treatment: The risk of surgical complications increases only slightly with age for elective surgery, but increases dramatically for emergency surgery. Radiation therapy appears a valuable method of cancer treatment in patients of all ages. Chemotherapy can be made safer by the following provisions: use of hemopoietic growth factors for patients aged 70 and older receiving moderately toxic chemotherapy (CHOP and CHOP-like); maintenance of hemoglobin levels at 12 g/dl with erythropoietin; adjustment of the dose of renally excreted agents to the glomerular filtration rate; selection of the best candidates for chemotherapy based on comprehensive geriatric assessment.

Validity and reliability of the FACT-G scale for use in the older person with cancer.

This project was designed to evaluate the Functional Assessment of Cancer Therapy General Scale (FACT-G) for use in the older patient with cancer. Subjects were administered the MOS Short Form Health Survey (SF-36) and the FACT-G scale. Subscale and total scores were compared using the Pearson product correlation test. FACT-G total and subscores were compared with the mixed aged cancer patient normative group of Cella et al. (1993). Good correlations were found between total and subscores of the SF-36 and the FACT-G in all areas except vitality. The mean total FACT-G score was 82.2 +/- 16.2 SD for the patients with cancer, and 92.3 +/- 11.8 SD for community-dwelling elderly (CDE). The FACT-G was able to discriminate between patients that received cancer care and CDE (p < 0.002). Subjects who scored higher on the FACT-G were found to have higher Eastern Cooperative Oncology Group Performance Status (PS). Subjects with a PS of 0 had a mean total FACT-G score of 87.9 +/- 14.4 SD. Subjects with a PS of 3 had a mean score of 59.0 +/- 23.2 SD. The FACT-G is a valid and reliable instrument for use in the older patient with cancer. The FACT-G is not an age-biased instrument.

Hematopoietic growth factors in the older cancer patient.

Aging is associated with a progressive decline in the functional reserve of multiple organ systems, which may lead to enhanced susceptibility to stress such as that caused by cancer chemotherapy. Myelodepression is the most common and the most commonly fatal complication of antineoplastic drug therapy and may represent a serious hindrance to the management of cancer in older individuals. This is already a common and pervasive problem and promises to become more so. Currently 60% of all neoplasms occur in persons aged 65 years and older, and this percentage is expected to increase as the population ages. This well-known phenomenon, sometimes referred to as squaring or the age pyramid, is caused by the combination of an increasing life expectancy and a decreasing birth rate. This article explores the use of hematopoietic growth factors in the older cancer patient after reviewing the influence of age on hemopoiesis and chemotherapy-related complications. The issue is examined in terms of effectiveness and cost. An outline of the assessment of the older cancer patient is provided at the end of the chapter as a frame of reference for clinical decisions.

Cancer in the elderly: tailoring treatment.

The body's ability to meet the stresses of cancer therapy declines in later life. Because the decline may vary from minimal to profound and is only weakly linked to chronologic age, a thorough functional assessment should be undertaken in all elderly cancer patients. The results can guide decisions about how to treat the cancer.

Cancer and aging. An evolving panorama.

This article illustrates how the nosology of cancer evolves with the patient's age. If the current trends are maintained, 70% of all neoplasms will occur in persons aged 65 years and over by the year 2020, leading to increased cancer-related morbidity among older persons. Cancer control in the older person involves chemoprevention, early diagnosis, and timely and effective treatment that entails both antineoplastic therapy and symptom management. These interventions must be individualized based on a multidimensional assessment that can predict life expectancy and treatment complications and that may evaluate the quality of life of the older person. This article suggests a number of interventions that may improve cancer control in the aged. Public education is needed to illustrate the benefits of health maintenance and early detection of cancer even among older individuals, to create realistic expectations, and to heighten awareness of early symptoms and signs of cancer. Professional education is needed to train students and practitioners in the evaluation and management of the older person. Of special interest is the current initiative of the Hartford Foundation offering combined fellowships in oncology and geriatrics and incorporating principles of geriatric medicine in medical specialty training. Prudent pharmacologic principles must be followed in managing older persons with cytotoxic chemotherapy. These principles include adjusting the dose according to the patient's renal function, using epoietin to maintain hemoglobin levels of 12 g/dL or more, and using hemopoietic growth factors in persons aged 70 years and older receiving cytotoxic chemotherapy of moderate toxicity (e.g., CHOP). To assure uniformity of data, a cooperative oncology group should formulate a geriatric package outlining a common plan for evaluating function and comorbidity. This article also suggests several important areas of research items: Molecular interactions of age and cancer Host-tumor interactions in the older tumor host Chemoprevention of cancer and aging Laboratory evaluation of aging Development of shorter forms of geriatric assessment Management of the frail cancer patients Clinical trials of tumor-specific issues.

Radiation therapy of the older patient.

Radiotherapy has a major role in the multidisciplinary approach to cancer therapy. It is widely used for curative and palliative treatment of cancer involving various sites. Radiotherapy is of particular benefit to older and frail cancer patients as an alternative to surgery and to systemic therapy. The available data on the sensitivity of normal tissues to radiotherapy in elderly patients strongly suggest that older patients with good functional status tolerate radiotherapy as well as younger patients and have comparable tumor response and survival rates. Aggressive radiotherapy should not be withheld from older patients because of chronological age alone.

Antineoplastic chemotherapy of the older cancer patient.

Cancer chemotherapy may be effective and safe in older patients if some proper provisions are made. Doses of chemotherapy should be adjusted to the patient's glomerular filtration rate, and his or her hemoglobin should be maintained for the duration of the therapy. For patients who are 70 years of age or older and who are receiving moderately toxic chemotherapy, growth factors should be used. The risk of mucositis increases with the age of the patient, so it is important to treat it aggressively at the first signs of the complication.

Breast cancer and aging. Clinical interactions.

The incidence and mortality rates of breast cancer increase with age. As the geriatric population grows, the number of breast cancer cases will reach epidemic proportions. The number of coexisting medical conditions also increases with advancing age. The presence and severity of comorbid conditions influences an individual's ability to tolerate procedures and treatments and must be considered in making disease-management decisions. Screening mammography can potentially save lives in older women. Women whose life expectancy exceeds 5 years should continue annual screening mammography. Choices for local definitive therapy, systemic adjuvant therapy, and treatment of metastatic disease should be based on patient preference and ability to tolerate the planned procedure. In general, otherwise healthy older women should be offered the same treatment options given to younger, postmenopausal women. Alternative, less aggressive, or nonstandard approaches are warranted in women whose life expectancy is limited or who are unable or unwilling to undergo standard management procedures.

Cancer in the frail patient. A coming epidemic.

With the aging of the population, frailty has emerged as a new clinical entity. The frail person has exhausted any functional reserve. Current criteria for the recognition of frailty include age of over 85 years, dependence in one or more activities of daily living, three or more comorbid conditions, and the presence of one or more geriatric syndromes. It is calculated that there are approximately 6 million frail patients in the United States and approximately 400,000 of them have cancer. Management of cancer in the frail person is mainly comprised of palliation, which may include some forms of chemotherapy, such as navelbine, gemcitabine, or low-dose taxanes.

Geriatric oncology: challenges for the new century.

The management of cancer in the older aged person represents one of the major immediate challenges of medicine. The response to this challenge involves answers to the following questions: I. Who is old? Currently. 70 years of age may he considered the lower limit of senescence because the majority of age-related changes occur after this age. Individual estimates of life expectancy and functional reserve may be obtained by a comprehensive and time-consuming multidimensional geriatric assessment. The current instrument may be fine-tuned and new instruments, including laboratory tests of ageing. may be developed. 2. Why do older persons develop more cancer? It is clear that ageing tissues are more susceptible to late-stage carcinogen. Older persons may represent a natural monitor system for new environmental carcinogens, and may also represent a fruitful ground to study the late stages of carcinogenesis. 3. Is cancer different in younger and older persons? Clearly. the behaviour of some tumors. including acute myeloid leukaemia, non-Hodgkin's lymphoma and breast cancer change with the age of the patient. The mechanisms of these changes that may involve both the tumour cell and the tumour host are poorly understood. 4. Can cancer he prevented in older individuals? Chemoprevention offers a new horizon of possibilities for cancer prevention: older persons may benefit most from chemoprevention due to increased susceptibility to environmental carcinogens. Screening tests may become more accurate in older individuals due to increased prevalence of cancer. hut may he less beneficial due to more limited patient life expectancy. 5. Do older persons benefit from cytotoxic treatment? The answer to this question partly stands on proper patient selection. partly on the development of safer forms of cancer treatment and prudent use of antidotes to chemotherapy toxicity. 6. What is the cost of treating older cancer patients? The treatment of older patients is generally more costly. This cost should be assessed against the cost of not treating cancer and promoting functional dependence. which by itself is extremely costly. 7. What are the endpoints of clinical trials in older cancer patients? With more limited life expectancy. the effect of treatment on quality of life is paramount. Reliable assessment of quality of life is essential for interpreting clinical trials in older individuals. 2000 Elsevier Science Ltd. All rights reserved.

The application of the principles of geriatrics to the management of the older person with cancer.

Is the patient going to die of cancer or with cancer? Is the patient going to suffer pain and disability due to cancer? Is the patient able to tolerate aggressive life-prolonging treatment? This paper tries to reply to the fundamentals of these questions by introducing the multidimensional assessment that evaluates areas where age-related changes are more likely. Chronologic age cannot be used to predict the degree of comorbidity and of functional deterioration of the single individual up to age 85 at least. Assessment of aging includes health, functional status, nutrition, cognition, socio-economic and emotion evaluations. This multidisciplinary assessment is referred to as comprehensive geriatric assessment (CGA). The risk of comorbid conditions increases with age and may result in underdiagnosis: in older patients, new symptoms may not be clearly recognized by the patient and may be dismissed by practitioners as manifestations of preexisting conditions. A meaningful assessment of comorbidity may be obtained with a comorbidity index. The Charlson scale and the Chronic Illness Rating Scale - Geriatric (CIRS-G), have enjoyed the widest acceptance. The Instrumental Activities of Daily Living (IADL) and the Activities of Daily Living (ADL) are the most sensitive assessment of function in older individuals. IADLs include shopping, managing finances, housekeeping, laundry, meal preparation, ability to use transportation and telephone and ability to take medications: in simple words, the IADLs are those skills a person needs to live independently. ADLs include feeding, grooming, transferring, toileting and are the skills necessary for basic living. Though a correlation exists among comorbidity, performance status, ADL and IADL, this correlation is not strong enough to be reflected in a single parameter. The Folstein Mini Mental Status (MMS), is the instrument of most frequent use to screen older individuals for dementia. The main problem with the MMS is lack of sensitivity to early stages of dementia. The Geriatric Depression Scale (GDS), a simple tool that can be completed by most patients at home, doubles the rate of detection of depression. The Mini Nutritional assessment is very sensitive to screen older persons for malnutrition. The risk of polypharmacy increases with age and partly results from the fact that older patients visit different practitioners. A CGA should also include evaluation of the so called Geriatric Syndromes like delirium, incontinence, osteoporosis, all of which represent a hallmark of frailty. The CGA may help the management of older individuals with cancer in at least three areas: detection of frailty, treatment of unsuspected conditions, removal of social barrier to treatment.

Management of the frail person with advanced cancer.

The frail population is increasing: currently, approximately 400,000 frail persons have cancer in the USA. Although the frail person is not a candidate for aggressive life-prolonging antineoplastic treatment, he/she is a candidate for aggressive symptom palliation. Most common symptoms include pain, especially bone pain, anemia, and fatigue. Destruction of cancer with antineoplastic treatment is pivotal to symptom palliation. A number of cytotoxic agents including gemcitabine, taxanes in low doses, vinorelbine, oral fluorinated pyrimidine, appear suitable for the management of metastatic cancer in the frail patient and should be tested in clinical trials.

Quality of life after adjuvant chemotherapy for breast cancer.

PURPOSE: To evaluate the quality of life of breast cancer patients previously treated with adjuvant chemotherapy. METHOD: Registry data were used to recruit a sample of breast cancer patients (N = 61; mean age = 51.6 years) with no current evidence of disease who had completed adjuvant chemotherapy between 3 and 36 months earlier (average = 15.87 months). In addition, a peer nomination procedure was used to recruit an age-matched comparison group of women with no history of cancer (N = 59; mean age = 51.5 years). Both groups were mailed a survey to complete that included the Medical Outcomes Study Short Form 36 (SF-36) and the Center for Epidemiologic Studies Depression Scale (CES-D). These data were used to test the hypothesis that breast cancer patients previously treated with adjuvant chemotherapy experience impaired quality of life relative to their peers and to identify demographic and medical factors associated with individual differences in patient quality of life. RESULTS: Consistent with predictions, the postchemotherapy group scored poorer than the noncancer comparison group on the CES-D and on six of the eight subscales as well as the physical component summary scale of the SF-36 (p < 0.05). With regard to individual differences in patient quality of life, younger age and unmarried status were positively related to poorer mental well-being and greater depressive symptomatology (p < 0.05). Time since cancer diagnosis and chemotherapy completion were also positively related to greater depressive symptomatology (p < 0.05). In contrast, none of the demographic or medical variables assessed were related to physical well-being (p > 0.05). CONCLUSIONS: Breast cancer patients appear to experience problems in multiple quality of life domains following the completion of adjuvant chemotherapy treatment. Demographic and medical characteristics explain individual differences in mental but not physical aspects of patient quality of life. These findings demonstrate the need for interventions to improve the quality of life in breast cancer patients previously treated with adjuvant chemotherapy.
