  • The population of Western countries is aging, and cancer in older aged persons is becoming increasingly common. The management of these neoplasms is a novel problem. Direct information on the outcome of cancer prevention and of cytotoxic chemotherapy in older individuals is scarce, especially for those aged 80 and over, and it is not clear whether the same process should direct medical decisions in younger and older persons. It is reasonable to assume that the benefits of cancer prevention and treatment diminish and the dangers increase with age.

  • There is growing evidence on the importance of studies focusing on mechanisms and strategies leading to cancer prevention. The plethora of approaches include regulation of oxidative stress using antioxidant therapies, carefully balanced diets and living habits, epidemiological evidence and molecular approaches on the role of key biological molecules such as antioxidant enzymes, vitamins, proteins and naturally occurring free radical scavengers as well as controversial results and clinical applications. These are some of the topics that this book highlights.

  • The goal of cancer treatment is first to eradicate the cancer. If this primary goal cannot be accomplished, the goal of cancer treatment shifts to palliation, the amelioration of symptoms, and preservation of quality of life while striving to extend life. The dictum primum non nocere is not the guiding principle of cancer therapy. When cure of cancer is possible, cancer treatments may be undertaken despite the certainty of severe and perhaps life-threatening toxicities.

  • In its fifth edition, Cancer Medicine has been named eponymously to honor its founding editors James F. Holland and Emil Frei III, two giants of medical oncology. The Holland-Frei Cancer Medicine reflects their dedication to innovative, comprehensive, and multidisciplinary care of cancer patients, as well as their belief in the importance of grounding such care in a more fundamental understanding of cancer biology. It is to their vision and the example that they have established over the last four decades that this book is dedicated.

  • Physical Activity Physical activity is associated with a decreased risk of colon and breast cancer. A variety of mechanisms have been proposed. However, such studies are prone to confounding factors such as recall bias, association of exercise with other health-related practices, and effects of preclinical cancers on exercise habits (reverse causality). Recommending adults to engage in at least 30 min of vigorous activity for ≥3 days a week is good health advice, though its effects on cancer incidence are unproven.

  • Improved understanding of carcinogenesis has allowed cancer prevention and early detection (also known as cancer control) to expand beyond the identification and avoidance of carcinogens. Specific interventions to prevent cancer in those at risk, and more sensitive and specific screening for early detection of cancer are the goals. Carcinogenesis is not simply an event but a process, a continuum of discrete cellular changes over time resulting in more autonomous cellular processes.

  • Joanna Didkowska PhD works in the Department of Epidemiology and Cancer Prevention, National Cancer Registry at the Maria Sklodowska Curie Memorial Cancer Center and Institute of Oncology in Warsaw, Poland. Since 1999, she has been Chair of the Association of Cancer Registries in Poland. She focuses on descriptive cancer epidemiology in Poland, especially prediction models, and the determinants of the health status of Poles and inhabitants of central and eastern Europe. She works on analyses of data from the National Cancer Registry.

  • Prostate cancer is the most common male cancer diagnosed in Western populations. Autopsy studies have shown that with increasing age, the majority of men will develop microscopic foci of cancer (often termed “latent” prostate cancer) and that this is true in populations that are at both high and low risk for the invasive form of the disease (1). However, only a small percentage of men will develop invasive prostate cancer. The prevalence of prostate cancer is, thus, very common; but to most men, prostate cancer will be only incidental to their health and death....

  • The epidemiology of esophageal cancer in the Western world has changed dramatically over the last two decades. Up until the 1970s most esophageal cancers were of the squamous cell type, affecting mostly elderly men drawn from the poorer social classes and influenced by smoking and alcohol consumption. Since then there has been a dramatic increase in the incidence of adenocarcinoma, which tends to affect more affluent white men, often in their most productive years of life

  • In the past 15 years, molecular biologists and geneticists have uncovered some of the most basic mechanisms by means of which normal stem cells in a certain organ or tissue develop into cancerous tumors. This biological knowledge serves as a basis for various models of carcinogenesis.

  • Neither randomized clinical trials nor meta- analysis are available and evidence is based on a number of retrospective studies with multivariate for mortality risk factors or data from national cancer registries (Gilliland et al., 1997; Hundahl et al., 1998). Unfortunately, very remarkable differences in patient’s selection, staging systems, and clinical management affect the available studies. In particular, radioiodine treatment is not routinely carried out in a standard manner and outcome results of different studies are thus not comparable (Sciuto et al., 2009).

  • The field of medical genetics has traditionally focused on chromosomal abnormalities (Chap. 63) and Mendelian disorders (Chap. 62). However, there is genetic susceptibility to many common adult-onset diseases, including atherosclerosis, cardiac disorders, asthma, hypertension, autoimmune diseases, diabetes mellitus, macular degeneration, Alzheimer's disease, psychiatric disorders, and many forms of cancer.

  • The application of current treatment techniques (surgery, radiation therapy, chemotherapy, and biological therapy) results in the cure of nearly two of three patients diagnosed with cancer. Nevertheless, patients experience the diagnosis of cancer as one of the most traumatic and revolutionary events that has ever happened to them. Independent of prognosis, the diagnosis brings with it a change in a person's self-image and in his or her role in the home and workplace.

  • Cancer arises through a series of somatic alterations in DNA that result in unrestrained cellular proliferation. Most of these alterations involve actual sequence changes in DNA (i.e., mutations). They may arise as a consequence of random replication errors, exposure to carcinogens (e.g., radiation), or faulty DNA repair processes. While most cancers arise sporadically, familial clustering of cancers occurs in certain families that carry a germline mutation in a cancer gene.

  • In 2007, primary carcinoma of the lung affected 114,760 males and 98,620 females in the United States; 86% die within 5 years of diagnosis, making it the leading cause of cancer death in both men and women. The incidence of lung cancer peaks between ages 55 and 65 years. Lung cancer accounts for 29% of all cancer deaths (31% in men, 26% in women). Lung cancer is responsible for more deaths in the United States each year than breast cancer, colon cancer, and prostate cancer combined; more women die each year of lung cancer than of breast cancer. ...

  • Breast cancer is a malignant proliferation of epithelial cells lining the ducts or lobules of the breast. In the year 2007, about 180,510 cases of invasive breast cancer and 40,910 deaths occurred in the United States. Epithelial malignancies of the breast are the most common cause of cancer in women (excluding skin cancer), accounting for about one-third of all cancer in women.

Esophageal Cancer Incidence and Etiology Cancer of the esophagus is a relatively uncommon but extremely lethal malignancy. The diagnosis was made in 15,560 Americans in 2007 and led to 13,940 deaths. Worldwide, the incidence of esophageal cancer varies strikingly.

  • Psychological distress increases with the intensity of cancer pain. Cancer pain is often under-reported and under-treated for a variety of complex reasons, partly due to a number of beliefs held by patients, families and healthcare professionals. There is evidence that cognitive behavioural techniques that address catastrophising and promote self-efficacy lead to improved pain management. Group format pain management programmes could contribute to the care of cancer survivors with persistent pain.
