title: Cancer incidence and survival in patients 65 years of age and older.
abstract: The impact of cancer on persons 65 years of age and older has been assessed by examining incidence rates and survival rates. For all cancers combined, the incidence rate shown in Table 4 for males 65 and older (2,468.2 per 100,000) is four times the age-adjusted rate for males 45 to 64 years of age (586.7). For elderly females, the incidence rate is twice that for females aged 45 to 64 (1,401.1 versus 609.7). Ratios of incidence rates for older versus younger males are about four to five for cancers of the stomach, colon, rectum, pancreas, and urinary bladder, and for leukemia; about three for cancers of the lung and kidney, and for non-Hodgkin's lymphomas; and 10 for cancer of the prostate. For females, the corresponding ratios are similar to those for males, although a little lower for cancers of the colon, rectum, and urinary bladder, and for leukemia, and a little higher for cancers of the stomach and pancreas. The ratios for breast, uterine cervix, uterine corpus, ovary, and lung are less than two. The relative survival rates for patients 65 and older are for many cancer sites only a few percentage points lower than rates for those 45 to 64 years of age (Table 5), suggesting that patients in this age group fare only a little worse than younger patients in escaping the effects of cancer once it has been diagnosed. Exceptions are cancer of the urinary bladder and non-Hodgkin's lymphomas for both men and women and cancers of the uterine cervix, uterine corpus, ovary, and kidney for women. For these sites, the survival rates for older patients are considerably lower than for their younger counterparts. For female breast cancer patients, there was no difference in the five-year relative survival rate for those 65 and older compared with those 45 to 64.
