Background: Bladder carcinoma often occurs in older patients who also may have other comorbid conditions that could influence the administration of surgical therapy. The current study was conducted to describe the distribution of comorbid conditions in patients with bladder carcinoma and ascertain whether these conditions, as grouped by the American Society of Anesthesiologists physical status classification, affected the choice of surgical therapy., Methods: The authors examined six population-based cancer registries from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program in 1992. A total of 820 individuals age 55 years and older was found. A random sample of newly diagnosed bladder carcinoma patients were stratified according to registry, age group (ages 55-64 yrs, ages 65-74 yrs, and age 75 yrs and older), and gender. Data regarding comorbid conditions were abstracted from the medical records and merged with routinely collected cancer registry data. The main outcome measures were the prevalence and distribution of comorbid conditions, American Society of Anesthesiologists physical status classification, and the receipt of cystectomy in patients with muscle invasion., Results: Hypertension, chronic pulmonary disease, arthritis, and heart disease were found to affect at least 15% of the study population. Approximately 38% of patients were current or former smokers. Greater than 90% of patients with superficial disease were treated with transurethral resection alone. Among those patients with muscle invasion, only 55% of those ages 55-59 years underwent cystectomy; this percentage dropped to 4% in patients age 85 years and older. Among patients with an American Society of Anesthesiologists physical status classification of 0-2, the cystectomy rate ranged from 53% in those ages 55-59 years to 9% in those age 85 years and older., Conclusions: There were no significant treatment differences noted with regard to age among patients with superficial disease. Among those patients with muscle invasion, those age 75 years and older were less likely to undergo radical cystectomy (14%) compared with patients ages 55-64 years (48%) and those ages 65-74 years (43%). Patient age may contribute to treatment decisions in patients with muscle-invasive disease, even when comorbidity is taken into account., (Copyright 2005 American Cancer Society)

Background: The American Cancer Society, the National Cancer Institute, the North American Association of Central Cancer Registries (NAACCR), the National Institute on Aging (NIA), and the Centers for Disease Control and Prevention, including the National Center for Health Statistics (NCHS) and the National Center for Chronic Disease Prevention and Health Promotion, collaborated to provide an annual update on cancer occurrence and trends in the United States. This year's report contained a special feature focusing on implications of age and aging on the U.S. cancer burden., Methods: For 1995 through 1999, age-specific rates and age-adjusted rates were calculated for the major cancers using incidence data from the Surveillance, Epidemiology, and End Results Program, the National Program of Cancer Registries, and the NAACCR, and mortality data from NCHS. Joinpoint analysis, a model of joined line segments, was used to examine 1973-1999 trends in incidence and death rates by age for the four most common cancers. Deaths were classified using the eighth, ninth, and tenth revisions of the International Classification of Diseases. Age-adjusted incidence and death rates were standardized to the year 2000 population, which places more emphasis on older persons, in whom cancer rates are higher., Results: Across all ages, overall cancer death rates decreased in men and women from 1993 through 1999, while cancer incidence rates stabilized from 1995 through 1999. Age-specific trends varied by site, sex, and race. For example, breast cancer incidence rates increased in women aged 50-64 years, whereas breast cancer death rates decreased in each age group. However, a major determinant of the future cancer burden is the demographic phenomenon of the aging and increasing size of the U.S. population. The total number of cancer cases can be expected to double by 2050 if current incidence rates remain stable., Conclusions: Despite the continuing decrease in cancer death rates and stabilization of cancer incidence rates, the overall growth and aging of the U.S. population can be expected to increase the burden of cancer in our nation.

It has been stated in this article and elsewhere that cancer patients aged 65 years and older deserve special attention as a target group for research efforts across the cancer-control spectrum. The available data show that the vulnerability of older persons to cancer is unmistakable. Clinicians will be treating more older patients as the nation ages. The future needs of this segment of the population must be anticipated. In this context, the following generic treatment questions are pertinent. What are the peculiarities of the aged host of which clinicians must be aware in evaluating the older cancer patient? Do various forms of cancer present differently in the elderly? How can be complications caused by the multiple pathologies inherent in the older patient be anticipated? What are the potential hazards and limitations of surgery, radiotherapy, and chemotherapy for older persons with cancer? What is known regarding increased risk of adverse reactions to medications, drugs, and interaction of drugs in older patients? The surveillance data and population estimates and projections presented in this article illustrate the extent of the problems of cancer in the elderly at the macro level. For the individual patient, the special knowledge of aging individuals and their health status based on geriatric medicine and gerontology that has been accumulating for the past several decades needs to be incorporated into the oncology armamentarium that has developed during the same period. The information and expertise from both fields must converge, and new knowledge must be developed at the aging/cancer interface and applied for the optimal treatment of cancer in the elderly.

Background: Cancer of the ovary is a disease of older American women with an incidence rate of 9.4 per 100,000 for those under 65 compared to 54.8 per 100,000 for those 65 years of age and over., Methods: Over 22,000 women were diagnosed with ovarian cancer between 1973 and 1987 within the Surveillance, Epidemiology and End Results (SEER) Program of the National Cancer Institute. SEER is a population-based program that covers nearly 10% of the U.S. population for cancer incidence and survival., Results: Ovarian cancer survival rates vary dramatically by stage. Within stage, however, differences are noted in survival by age, with younger women surviving better than older women even after adjustment for the general life expectancy of each age group (relative survival). For Stages III-IV disease, women under 45 years of age have a 5-year relative survival rate of over 45% compared to only 8% for those 85 years of age and over. Between 1973-1977 and 1983-1987, the treatment for Stages III-IV disease has changed. For all age groups, there were sharp increases in the percentage having surgery and chemotherapy/hormonal therapy and decreases in those having surgery and radiation as part of the first course of therapy. Over 40% of women 85 years of age and over did not receive any definitive treatment according to the hospital medical record. In 1983-1987, younger women received more combination therapy (surgery with chemotherapy/hormonal therapy) versus older women who received more single modalities such as surgery only or chemotherapy/hormonal therapy only., Conclusions: Older women with ovarian cancer are treated less aggressively than their younger counterparts and have poorer survival rates.
