Treating cancer and no-cancer pain in older and oldest old patients.

Pain is one of the most frequent reasons for consultations in general practice, presenting either alone or associated with some comorbidity. In all care settings for older and oldest old patients, a gap exists between best-practice recommendations and current clinical practice. Clinical manifestations of persistent pain are often complex and multifactorial in the frail population, so the approach to pain management in older persons differs from that for younger people. The purpose of this review is to describe the best approach to assess and manage persistent cancer and no-cancer pain in the elderly, to explain the principles of pain treatment in this so often frail and complex population and compare the different drugs that should be used or avoided in older and oldest old patients considering the agerelated physiologic changes. Considerable emphasis is placed on conditions more common in the elderly such as neuropathic pain or typical subsets of the aging population such as the assessment of pain in people with dementia.

Treating cancer in older and oldest old patients.

The so-called "silver tsunami" is a metaphor that the individuals 65 and older represent the most rapidly growing segment of the Western world population. Aging is an ongoing process that leads to the loss of functional reserve of multiple organ systems, increased susceptibility to stress, it is associated with increased prevalence of chronic disease, and functional dependence. Determined by a combination of genetic and environmental factors, this process is highly individualized and poorly reflected in chronologic age. The heterogeneity and the complexity of the older old population represent the main challenge to the treatment of cancer in those patients. We should discern "fit" elderly in whom standard cancer treatment appears to be comparable to a younger population and "unfit" or "frail" elderly, in which the risks of the treatment may overwhelm potential benefits. There are many aspects that have to be assessed before treating an elderly patient, or before to choose the treatment itself. In our review we will try to explain and describe the meaning and the most important aspects related to the oldest old complex patients, and how to manage those patients.

Prevalence of aging population in the Middle East and its implications on cancer incidence and care.

The Middle Eastern population is aging rapidly, and as aging is the main risk factor for cancer, the incidence and prevalence of that disease are increasing among all the populations in the region. These developments represent huge challenges to national and community-based health services. At the current state of affairs, most Middle Eastern countries require the cooperation of international agencies in order to cope with such new challenges to their health systems. The focus and emphasis in facing these changing circumstances lie in the education and training of professionals, mainly physicians and nurses, at the primary, secondary and tertiary levels of health services. It is imperative that these training initiatives include clinical practice, with priority given to the creation of multidisciplinary teams both at the cancer centers and for home-based services.

Polypharmacy and the management of the older cancer patient.

Aging is associated with polymorbidity and polypharmacy. In the absence of a consensual definition, polypharmacy has been defined according to the number of drugs that an individual takes or to the presence of the risk of at least one severe drug interaction. In older cancer patients, polypharmacy is at least as common as it is in individuals of the same age without cancer. The management of cancer itself may result in the addition of more medications to counteract the adverse effects of antineoplastic treatment. Polypharmacy may be necessary to control the multiple health conditions of the older person, but it may represent a risk factor for more complications from antineoplastic therapy, and it may affect the outcome of cancer treatment. Polypharmacy is also associated with increased cost. The criteria proposed for the management of polypharmacy include the assessment that all medical conditions are properly treated, the avoidance of drug interactions, and of drugs that may compromise the outcome of antineoplastic treatment and the choice of drugs with the lowest risk of complications in older individuals.

Promoting new approaches for cancer care in the Middle East.

Cancer is now the fastest growing killing disease in the Middle East. Accordingly, there is an urgent need to train local health professionals: oncologists, palliative care experts, oncology nurses, psychologists, along with social workers, physiotherapists and spiritual counselors on strategies for early detection, curative therapies and palliation. Professionals in the region, along with the public, need to convince medical administrators, regulators and policymakers about investing in education and training of YOUNG professionals, as well as those with already proven experience in cancer care. Training is the basis for any future cancer care program, which aims at the integration of palliative care practices into standard oncology care across the trajectory of the illness.

Improvement of a rapid screening test for chronic granulomatous disease.

Diagnosis of CGD is made by demonstrating absent or markedly reduced oxidase activity in stimulated neutrophils. The screening test proposed is based upon the naked eye evaluation of the reduction of NBT on a solid surface. It seems to be a useful tool for rapid and inexpensive detection of CGD patients, especially for large-scale screening purposes. The test was carried out on forty-five subjects: two males affected by CGD, three female carriers and forty healthy donors. The test confirmed the results obtained with flow cytometric and NBT assays.

Death and dying: what the patient wants.

A good death and a death with dignity may be achieved when death is congruent with the personal values of the patient. It behooves the practitioner to recognize these values and to cater to them. This paper describes effective communication with the dying person, and the partnership of treatment team, patient and family in face of the patient death. To identify and define the patient wishes it is necessary to learn how to interpret the patient's non verbal as often patients are unable to formulate the questions they wish to ask concerning their passing. These difficulties stem from several cultural factors including concern about disturbing the practitioner. It is the treatment team's responsibility to facilitate this discussion. A good death is achieved when symptoms are controlled and when patients and family recognize death as a unique living experience to be treasured as any other living experience. A death with dignity brings healing, that is always possible even when cure is out of reach. Patient's and practitioner's values may be at odd in face of controversial issues including euthanasia, assisted suicide and terminal sedation. Though he/she should not be compelled to execute these requests, the practitioner should be able to entertain an open discussion with the patient concerning these issues. Open communication and reflective listening even in presence of disagreements are the venue of healing. The study of death and dying requires novel approaches including personal narrative and qualitative research to complement traditional research instrument, such as questionnaire that cannot embrace the whole human dimension.

Anemia, fatigue and aging.

Aging is associated with increased incidence and prevalence of both cancer and anemia. Cancer and aging may conspire in making anemia more frequent and more severe. This article reviews the causes and the consequences of anemia in the older individual. The most common causes include chronic inflammation that is a typical manifestation of aging, iron deficiency that may be due to chronic hemorrhage, malabsorption and Helicobacter pylori infection, cobalamin deficiency from malabsorption and renal insufficiency. Other causes of anemia whose prevalence is not well established include myelodysplasia, copper deficiency, hypothyroidism, and sarcopenia. Anemia is associated with increased risk of mortality, functional dependence, dementia, falls, and chemotherapy-related toxicity. When correcting the anemia of older cancer patients one should remember that the erythropoietic stimulating agents (ESA) may stimulate cancer growth and cause thrombosis. These products may be safe when given exclusively to patients receiving chemotherapy and when the hemoglobin levels are maintained below 12 g/dL.

Treating elderly patients with hormone sensitive breast cancer: what do the data show?

Elderly patients with breast cancer frequently present with one or more comorbid conditions in addition to their cancer, and this can complicate clinicians' treatment decisions. Declining estrogen levels increase the risk for conditions such as cardiovascular disease and osteoporosis in the elderly. Evidence from clinical trials suggests that the elderly are frequently underrepresented; this may be due to an inherent reluctance among physicians to prescribe the latest, most effective therapies and/or recommend elderly patients for participation in clinical trials. Nonetheless, there is evidence that breast cancer in the elderly is generally more indolent than in younger patients, with a low proliferative and invasive capacity and a high degree of hormone responsiveness, making elderly patients ideal candidates for adjuvant endocrine therapies. The aromatase inhibitors, including anastrozole, letrozole, and exemestane, have proven to be well tolerated and superior alternatives to tamoxifen for post-menopausal women with hormone-sensitive breast cancer, whether used upfront or sequentially with adjuvant tamoxifen. Although the elderly have also been underrepresented in clinical trials of the aromatase inhibitors, evidence from the major trials has not shown any decrement in efficacy or major safety concerns when these drugs are used in older populations. While recently published data from MA.17 and the Breast International Group 1-98 showed letrozole to be effective irrespective of age, clinicians should carefully consider underlying comorbidities when prescribing adjuvant endocrine treatments to elderly patients with breast cancer.

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.

Management of breast cancer in the older woman.

BACKGROUND: Approximately half of all breast cancer cases occur after age 65. Several aspects for the treatment of early breast cancer may be influenced by patient age, including postoperative irradiation after partial mastectomy, axillary lymphadenectomy, primary medical treatment of early breast cancer, and adjuvant chemotherapy. METHODS: The authors review the literature regarding age-specific issues in the management of breast cancer, and they report their own experience in treating older women with breast cancer. RESULTS: In terms of survival and disease-free survival, tamoxifen alone in primary breast cancer is inferior to surgical treatment followed by adjuvant tamoxifen. Tamoxifen alone should be reserved for patients with absolute contraindications to mastectomy. Adjuvant chemotherapy is beneficial to women with hormone receptor-poor tumors. In those with hormone receptor-rich tumors, adjuvant chemotherapy is beneficial for HER2-positive tumors, and the regimen should contain an anthracycline. CONCLUSIONS: Although the risk of local recurrence after partial mastectomy declines with increasing age, the decision to forego radiation therapy is individualized based on risk of recurrence and on patient desires and resources. The advent of lymph node mapping obviates the need for lymphadenectomy in most patients. The benefits and risks of adjuvant chemotherapy should be individually assessed according to tumor stage, life expectancy, comorbidity, and expected tolerance of treatment.

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.
