metastases in the vertebrae may cause spinal cord compression (SCC) and result in pain or loss of sensation and paralysis – an oncological emergency, invasion of small local blood vessels, causing chronic bleeding and anaemia; when major vessels such as the carotid artery erode, a haemorrhage may be sudden and fatal, uncontrollable growth causing necrosis or ulceration which may be internal or external – often termed ‘a fungating tumour’, infiltration by the cancer cells into the bone marrow compromising haemopoiesis (blood cell production) and leading to increased susceptibility to infection, metabolic alterations – there are many tumour-specific metabolic imbalances such as those affecting the kidneys, liver and pancreas. Despite being taught about the risks of smoking, teenage smokers may consider themselves to be young and healthy and therefore not ‘at risk’. Certain hormones are thought to promote some tumours. Serous membranes such as the pleura or the peritoneum may be invaded by tumours, either locally from the primary tumour or from nearby metastases. Here's an overview of assisted living and nursing home services: gas-trointestinal system as a result of tumor activity and cancer treat-ment. Before inva-sive nutritional strategies are instituted, the nurse and emesis for occult blood. Within hospitals, clinical nurse specialists incorporate cancer awareness and prevention in their roles, with many involved in local and national initiatives such as cancer site-specific awareness weeks and health promotion in schools. A UK collaborative trial of ovarian cancer screening (UKCTOCS) is underway to answer the question of whether or not early detection will save lives. decreased fatigue, Exhibits improved body image and self-esteem, Experiences no complications, such as infection, or avoided to minimize further trauma. is known to cause cellular mutations and cancer. CNS, central nervous system; NHL, non-Hodgkin’s lymphoma. alterations in oxygenation and electrolyte balances. Finally, and most problematically, it must be determined whether detecting the cancer type at an early stage will prolong life (Segnan et al 2004). An important component of the nurse’s role is How to inform patients, Informing patients of their diagnosis: ethical considerations, Patients have a right to autonomy, or self-determination. Thrombocytopenia, a As the scientific evidence for the chemical signals is complex this text will concentrate on the key genetic components involved. Topical anti-inflammatory and anesthetic during treatment. The process is called carcinogenesis. Women in the UK are first offered screening at age 25 years. applicators may be used in place of a toothbrush for painful oral tissues. BLEEDING. The test must have both a high degree of sensitivity, reducing the risk of false-negative results, and specificity, reducing the psychological trauma and expense of treating false-positive results. Access the European code against cancer and Cancer Research UK websites and consider their advice on reducing cancer risk. Personal Details. For such people, possible avoidance of lung cancer is not worth the cost of surrendering the immediate gratification and social status offered by smoking. Increasingly, there is also recognition of the important role that nurses have in caring for patients with cancer. A few select authors will be chosen to ... Latest Entry: 12/31/2020 The Impact of Delays in Low-Income Women’s Breast Cancer Experiences Increasing knowledge about newer biological factors such as HER2/neu receptors and proliferative index (rate of cell division in the tumour) has altered the way adjuvant treatments (see p. 812) are prescribed and these indicators are increasingly used to predict prognosis. infecting organism is identified because of the high incidence of mortality Damage to the genetic components of the cells can result in loss of function and ability to regulate growth. One in three people in the UK risk developing cancer in their lifetime. folds. The 20 most commonly diagnosed cancers are shown in Figure 31.2. The development of an accurate and cost-effective method of screening at-risk sections of the population is problematic for several reasons. The exact manner in which a cancer moves from being a carcinoma in situ to one which is capable of invasion and spread to other organs or tissues is not clear; however, it is thought to be partly due to physiological changes occurring in tumour cell membranes which reduce their adhesion to other cells. However, epidemiological studies have identified certain causative factors, termed ‘carcinogens’. A study by Schofield et al (2003) showed that clinical practices that are linked to lessening anxiety include preparing the patient for a possible cancer diagnosis, having significant others present at diagnosis, being given as much information as desired in understandable language, having questions answered, talking about feelings and being given reassurance. It provides a better estimation of prognosis. All have the potential to make a real difference in practice. oxygenation. the major pathogenic organisms. them from becoming dry and cracked. Thereafter the test is offered at 5-year intervals until women reach the age of 64. The temporal relationship between smoking and lung cancer was defined in the 1950s by studies undertaken by Doll & Hill (1954). Inherited cancers constitute 5–10% of all cancers. Psychological impact of diagnosis and staging, It is very common for patients to be aware that they have cancer before they are told formally of their diagnosis. Cancer Nursing Practice. How to inform patients in full of their diagnosis, and when this should be done are ongoing issues of ethical debate (Box 31.5). Tumour cells may spread directly in the CSF. Genetic changes or mutations may be either somatic (acquired) or germline (inherited). Mutation of the BRCA2 gene, which is most commonly associated with breast cancer risk, causes a fivefold increased risk of prostate cancer; this risk can be more than sevenfold higher in men under 65 years (CRUK, 2013b). Tumours vary greatly in their doubling time but, contrary to popular belief, their growth is not as rapid as that of normal tissues. It would seem appropriate that a nurse is present at such discussions because they can follow up the conversation and help the patient to strike a balance between realistic hope and the acceptance of reality. The increased incidence of cancer with age is thought to be attributable to: At least 70% of cancers occur in epithelial cells which are constantly exposed to external, ingested or inhaled substances. Two ethical principles are central to the discussion of whether it is always right to tell a patient the whole truth about their diagnosis: these are the principles of autonomy and of beneficence (see further reading, e.g. The UK political and health care agenda has recognised cancer as a high priority area for over a decade. These factors include physical agents, chemical agents, viruses and diet. Broad-spectrum antibiotic coverage or clinicians agree that good oral hygiene that includes brushing, flossing, and procedures carried out for diagnosis and therapy. Transvaginal ultrasound and detection of a raised cancer antigen (CA125) in the blood provide two possible techniques for the screening of ovarian cancer. This creates misinformation and inconsistency surrounding the disease. The ability of the cell to inhibit (switch off) growth is regulated by a tumour suppressor gene, the activity of which was revealed when investigating the childhood hereditary cancer retinoblastoma. Despite recent debates about the quality of over 40 years of trials, it is generally agreed that there is a clear benefit and reduction in mortality from breast cancer from screening women over the age of 50 years by mammography every 2 years (IARC 2002). smoking cessation, healthy eating. Projects have been developed to assist smokers to quit, particularly in areas with high levels of deprivation, prisons, the army and working men’s clubs. ALL, acute lymphoblastic leukaemia; CML, chronic myeloid leukaemia. sepsis, and no episodes of bleeding or hemorrhage. Table 31.2 Classification by tissue type of malignant tumours. Comprehensive long-term strategies are continually being developed to shape cancer services, focusing on all aspects of the patient’s cancer journey, ensure equity of care and invest in equipment and the cancer workforce. and nonpharmacologic approaches offer the best methods of managing cancer pain. However, accurate staging of the extent of the disease is vital for the following reasons: The most common internationally used method of defining disease stage is the TNM system (Sobin & Wittekind 2002), in which: Agreed staging criteria exist for each cancer, such as those staging systems used for lung cancer (Box 31.3), gynaecological, testicular cancers, etc. Cancerquest.). agents may be prescribed to promote healing and minimize discomfort. carefully for changes indicating blood loss. In addition, clinic schedules should allow time to provide support. If adherence to health care programmes is to be achieved, nurses need to understand an individual’s personal health beliefs and how information is interpreted. Scott-Brown et al 2007. J Nurs Care 6: e136. Neurologic assessments are per-formed to detect To survive within the host the forming tumour seeks out a new blood supply to maintain its growth which results in small fragments of tumour splitting off and travelling to distant sites to form secondary tumours (metastases); the cancer is said to have metastasised. Light-skinned or freckled individuals who are unable to manufacture sufficient protective melanin are particularly at risk (see, Ninety per cent of all lung cancers can be attributed to tobacco smoking. various degrees of cell differentiation – well differentiated to totally undifferentiated, variable growth rate – may be uncoordinated; some are slow growing. Unlike years ago, patients are now normally told their diagnosis, with a discussion of prognosis – often a medical uncertainty – and the level of information is tailored to the individual’s needs. It is heartbreaking to see poor health prognosis among pediatric cancer patients but on the other side, it is priceless to see a child cancer patient fully recover from the disease. See website Critical thinking question 31.1. Political action has included a comprehensive ban on tobacco advertising, a smoking ban in public places and the workplace, the setting up of new stop-smoking clinics and a smokers’ helpline, nicotine replacement patches and bupropion available on prescription, as well as a major health education campaign in schools aimed at preventing youngsters from starting to smoke (Department of Health 2000, SEHD 2004). A 2002 article in JAMA showed a clear association between a nurse being assigned more patients and increased risk of 30-day mortality. Nursing home residents (including any cancer patients) are already supposed to be receiving 24/7 care. It is very common for patients to be aware that they have cancer before they are told formally of their diagnosis. Countries where the average diet is high in fat and protein appear to have a high incidence of breast cancer, and low-fibre diets are thought to contribute to bowel cancer. of life. It may seem obvious that to tell lies or withhold the truth is wrong. Caring for cancer patients can be physically, mentally and emotionally demanding. Survivors of the atomic bomb explosions in Hiroshima and Nagasaki in Japan experienced a high incidence of leukaemia and skin cancer. fever may be related to a variety of noninfectious conditions, including the The prognosis and outcome of patients with cancer is improved considerably if the tumour is detected at an early stage. However, research has suggested that denial as a coping mechanism is sometimes necessary for the preservation of well-being during a crisis, allowing an individual time to mobilise the resources to cope with the seriousness of their disease (Moyer & Levine 1998). devices are beneficial for patients with impaired mobility. Light-skinned or freckled individuals who are unable to manufacture sufficient protective melanin are particularly at risk (see Ch. This awareness derives from their experience of symptoms, tests and, in some cases, surgery and from the non-verbal communication of staff or relatives. We think of caregivers as unpaid loved ones who give the person with cancer physical and emotional care. Cigarette smoking has now clearly been identified as a major cause of cancers of the mouth, pharynx, larynx, bladder and pancreas, whilst contributing to many others. Palliative care is a solution for improving the quality of cancer care. There is no evidence to suggest that acceptance correlates positively to survival in cancer (Spiegel 2001). Metastatic invasion (spread) may occur in one of four ways (see Figure 31.1): Tumour cells may invade the lymphatic vessels and grow in clumps and cords, establishing themselves en route in local lymph nodes. The study did not intend to generalise its findings to other units, but to produce local recommendations. This continues every 3 years until they reach the age of 49 years. The nurse administers fluids and blood Cancer is associated with increasing age. Dan wanted to know why staging was needed and the specialist nurse explained the purpose of staging and outlined the tests that would be necessary. The denser breast tissue of premenopausal women makes mammograms difficult to interpret in this age group. Caring for child cancer patients is physically demanding and emotionally exhausting for nurses. Nursing home care for terminally ill cancer patients was organized according to nursing care plans that were based on diagnoses as recommended by the North American Nursing Diagnosis Association (NANDA). The service became available throughout the UK in 2009. enzymes, such as gastrin; this leads to. The Japanese have a low incidence of breast cancer in comparison to the UK and USA but a high incidence of stomach cancer. The tests were carried out and their results were as follows: These tests showed that Dan had stage IV testicular teratoma (see staging system above). The HER-2/neu receptor belongs to the epidermal growth factor receptor family which is one of the receptors critical in controlling the pathway for epithelial cell growth and differentiation, and possibly angiogenesis (Karunagaran et al 1996). Several government publications have taken on ‘The Cancer Challenge’, with measures to promote a ‘pro-health’ culture (Department of Health 2000, Scottish Executive Health Department [SEHD] 2004). surgery) are termed, Nursing patients with respiratory disorders, Nursing patients with musculoskeletal disorders, Nursing patients with disorders of the ear, nose and throat, Nursing patients with gastrointestinal, liver and biliary disorders, Nursing patients with disorders of the breast and reproductive systems, Alexanders Nursing Practice Hospital and Home, Philadelphia chromosome t(9;22)(q34;q11) [BCR/ABL], Primary diagnosis, detection of residual disease after treatment, Squamous: surface epithelium, cell lining covering body cavities, organs and tracts, Squamous cell carcinoma, e.g. Accepted screening techniques include mammography and clinical breast examination, although Baxter (2001) has concluded that breast self-examination is of no benefit in routine screening. Geographical variations across the world in the incidence of cancer provide clues to the lifestyles of different populations. Women who inherit a mutation in these genes may face a 50–85% lifetime risk of developing breast cancer including an increased risk for ovarian cancer (Calzone & Biesecker 2002). During scientific research on viruses and how they propagate and reproduce within their host, scientists discovered extremely important genes involved in regulation of cell growth. with neutropenia are treated with broad-spectrum antibiotics before the Vasopressor agents are wound drainage, exudate, sputum, urine, stool, or blood are obtained. The Calman Report focused around the patient and their family, care being delivered in specific designated cancer centres and cancer units in partnership with each other. However, as with PSA, CA125 may be elevated in non-malignant conditions. , an inflammatory response of the oral tissues, commonlydevelops within They cannot make decisions about their treatment or the future if they are not fully aware of their diagnosis. The 20 most commonly diagnosed cancers (ex NMSC), UK, 2006 (Cancer Research UK, info.cancerresearchuk.org/cancerstats/incidence/commoncancers/, Cancer is associated with increasing age. 35). Women aged 65 or over are only offered a smear test if they have not had a smear since they reached 50 or have recently had an abnormal smear. Identification of the steps involved in carcinogenesis has led directly to the discovery of molecular tumour markers (Table 31.1). The function of the “Author on Call” blog is to allow our readers and authors to interact with each other in a unique way. The matter is seldom as simple as the choice between lying and truth-telling, and each case must be considered individually.
