  • According to the National Cancer Institute, cancer continues to take a devastating toll. Among women in the United States, cancer is the second-leading cause of death after heart disease. Medical researchers fighting against cancer have made significant progress, however. In recent years, cancer incidence rates have been stable, and—although the annual rate of decline in cancer death rates among men have been twice as large as the declines in women—mortality has decreased for ten of the top 15 cancers in women.

  • Immune system is composed of innate and adaptive responses and plays critical roles in cancer development and destruction. A century ago, Paul Ehrlich postulated that cancer would be quite common in long-lived organisms if not for the protective effects of immunity. About 50 years later, Burnet and Thomas proposed the concept of cancer immunosurveillance based on the experimental evidence of immune recognition of tumor antigens expressed on tumor cells (Dunn et al. 2004 ) . In 1971, the US Congress created a National Cancer Act – a War on Cancer.

  • Table 86-2 5-Year Survival Rate for Breast Cancer by Stage Stage 5-Year Survival, % 0 99 I 92 IIA 82 IIB 65 IIIA 47 IIIB 44 IV 14 Source: Modified from data of the National Cancer Institute—Surveillance, Epidemiology, and End Results (SEER). Estrogen and progesterone receptor status are of prognostic significance. Tumors that lack either or both of these receptors are more likely to recur than tumors that have them. Several measures of tumor growth rate correlate with early relapse. S-phase analysis using flow cytometry is the most accurate measure.

  • Clinical trials enable scientific discoveries to advance patient care, and they also inform and guide subsequent research. The National Cancer Institute (NCI) supports the largest U.S. network of clinical trials of any type, of which the largest component is the Clinical Trials Cooperative Group Program (informally known as the Cooperative Group Program). It currently comprises 10 Groups that involve more than 3,100 institutions and 14,000 investigators who enroll more than 25,000 patients in clinical trials each year.

  • Countless organizations have their own intricate and well-developed thesauri that have been refined over many years. With consummate converters, these thesauri can become a strong and useful element on the semantic web. Like the Thésaurus from the National Cancer Institute, many are available in an unusual form of XML, or not in XML at all. As in this case, simple translations using standard XML parsers often will not be a reasonable solution for making the transition to RDF or OWL. The most time...

  • Differentiated thyroid cancer is the fastest‐growing cancer in women; it increased 2.4% per year during 1980 to 1997 and 6.5% per year during 1997 to 2006 in the USA according to the National Cancer Instituteʹs Surveillance Epidemiology and End Results (SEER). On the other hand, the refinement of new approaches for surveillance of patients with an established diagnosis of thyroid cancer is leading to the observation that many patients, previously thought to be cured, have evidence of minimal residual disease, a condition with which we still do not know how to manage properly....

  • 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).

  • I am very grateful to the special group of distinguished scientists who made up the Panel and Secretariat for this major review of the evidence on food, nutrition, physical activity and cancer. The vision of WCRF International in convening this Panel and confidence in letting a strong-willed group of scientists have their way is to be highly commended. In our view, the evidence reviewed here that led to our recommendations provides a wonderful opportunity to prevent cancer and improve global health. Individuals and populations have in their hands the means to lead fuller, healthier lives.

  • The National Cancer Guidance Steering Group, as it is now called, was set up soon after the Calman-Hine report was published. It was charged with developing guidance for the implementation of the new policy in NHS services for the common cancers, starting with breast. There was no precedent for this type of document, and apart from the recognition that the guidance should complement existing clinical guidelines, no clear picture as to what the documents should be like, nor clarity about the ground they should cover.

  • Some adenomas produce too much adrenal steroid hormones. Sometimes the excess hormone can cause symptoms. Many of the hormone-related symptoms of adenomas are the same as those from adrenal carcinomas (cancers). These symptoms are discussed in the sections, “Can adrenal cancer be found early?” and “How is adrenal cancer diagnosed?” Adenomas are much more likely than carcinomas to produce high levels of aldosterone, which can cause high blood pressure. Treatment: Adenomas can be cured by removing the adrenal gland that contains the adenoma.

  • A substantially greater proportion of women with breast cancer are receiv- ing chemotherapy and/or hormone therapy than before 1988. Earlier symptomatic presentation and greater use of adjuvant therapy since 1988 has had a marked impact, reducing mortality rates from breast cancer, in addition to the specific contribution from the NHSBSP. Although some have questioned the value of screening for breast cancer, the scientific evidence demonstrates clearly that regular mammographic screening between the ages of 50 and 70 years reduces mortality from the malignancy.

  • Most inherited cases of breast cancer are associated with two abnormal genes: BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2). According to the National Cancer Institute, women with an abnormal BRCA1 or BRCA2 gene have about a 60% risk of being diagnosed with breast cancer during their lifetimes (compared to about 12% for women overall). Their risk of ovarian cancer is also increased. Abnormal BRCA1 or BRCA2 genes are found in 5% to 10% of all breast cancer cases in the United States. Other types of inherited gene abnormalities are less common.

  • We first highlight psychological and psychosocial issues associated with breast can- cer, and then underscore specific psychosocial variables that may play a role in the dis- ease. Further, we bring to light the current literature of psychosocial interventions for patients with cancer. We then introduce preliminary research from an on-going study funded by the National Cancer Institute (NCI). This is a pilot study intended to explore psychosocial factors and quality of life, preparatory to embarking on a larger scale, long- term study.
