Survival
(Five year follow-up for cases diagnosed in 2002 now available)
Life After Cancer

Five-year survival rates have improved for all sites combined.

Cancer Survival

Advances in the ways that cancer is diagnosed and treated have increased the number of people who live disease-free for long periods of time. This report looks at trends in 5-year survival rates for cancer, the time period traditionally associated with good prognosis. However, some people will experience a recurrence of their cancer after 5 years.

In 2007, more than 11.7 million Americans were alive after having been diagnosed with invasive cancer. Among survivors, nearly 2.6 million were living with a previous diagnosis of female breast cancer, more than 2.2 million had been diagnosed with prostate cancer, and more than 1.1 million had been diagnosed with colorectal cancer. More than 1.7 million of 11.7 million Americans diagnosed with invasive cancer were longer-term survivors (14.7 percent) diagnosed at least 20 years earlier.

Measure

Five-year relative cancer survival rate: The proportion of patients surviving cancer 5 years after diagnosis calculated in the absence of other causes of death. This rate is a ratio (expressed as a percentage) of the proportion of observed survivors in a cohort of cancer patients to the proportion of expected survivors. This report shows survival rates for cancers of the prostate, female breast, colon/rectum, and lung. It also shows survival rates for all cancers combined.

Period – 1975–2002 (year diagnosed)

Trends – Mostly rising.

All cancer sites combined: Generally rising since 1975, except for a stable period during 1992–1995

Prostate: Generally rising since 1975, except for stable periods during 19921995 and 19992002

Female breast: Rising since 1983

Colorectal: Generally rising since 1975, except for non-significant change during 1990–1994

Lung and bronchus: Small but significant rise since 1988. Five-year survival remains less than 20 percent

Among the four cancer sites listed above, 5-year survival rates are highest for prostate and female breast cancers, intermediate for colorectal cancer, and lowest for lung cancer.

Most Recent Estimates

Of the patients diagnosed with cancer (all sites) in 2002, 68.5 percent survived cancer for at least 5 years. Among those who were children (aged 19 years and younger) at the time of their diagnosis in 2002, 80.9 percent survived cancer for at least 5 years.

Healthy People 2010 Targets

Increase to 70 percent the proportion of cancer survivors who are living 5 years or longer after diagnosis.

Groups at High Risk for Limited Survival

Late stage at diagnosis is associated with limited survival. Causes of disparity in late stage cancer diagnosis vary by site, but may include factors related to low socio-economic status (e.g., health insurance, income, or education) or related demographic attributes (e.g., age, gender, or race and ethnicity minority). This association supports the need for continued development of early detection and stage-appropriate treatment strategies, as well as expanded efforts to ensure that all Americans have equal access to these life-saving interventions.

Key Issues

Improved survival rates result from a combination of early detection, better treatments, and improved supportive care. It is difficult to separate out the contribution of each factor. Caution is also warranted against over-interpretation of improved survival as a result of early detection via screening (lead-time bias).

Despite the positive trends in 5-year survival for three of the most common cancers, lung cancer survival rates remain low. Prevention efforts to reduce the incidence of lung cancer would therefore contribute to improvement in overall cancer survival rates for all cancers combined.
