The report appears early online in the Journal of the National Cancer Institute (JNCI) and includes a special section, which this year focuses on survival expressed as percentage. It finds that several but not all cancer types showed a significant improvement over time for both early- and late-stage disease, and varied significantly by race/ethnicity and state.
“While trends in death rates are the most commonly used measure to assess progress against cancer, survival trends are also an important measure to evaluate progress in improvement of cancer outcomes,” said Ahmedin Jemal, D.V.M., Ph.D., of the American Cancer Society and lead author of the study. “We last included a special section on cancer survival in 2004, and as we found then, survival improved over time for almost all cancers at every stage of diagnosis. But survival remains very low for some types of cancer and for most types of cancers diagnosed at an advanced stage.”
Compared to cases diagnosed in 1975-1977, five-year survival for cancers diagnosed in 2006-2012 increased significantly for all but two types of cancer: cervix and uterus. The greatest absolute increases in survival (25 percent or greater) were seen in prostate and kidney cancers as well as non-Hodgkin lymphoma, myeloma, and leukemia.
Cancers with the lowest five-year relative survival for cases diagnosed in 2006-2012 were pancreas (8.5 percent), liver (18.1 percent), lung (18.7 percent), esophagus (20.5 percent), stomach (31.1 percent) and brain (35 percent); those with the highest were prostate (99.3 percent), thyroid (98.3 percent), melanoma (93.2 percent) and female breast (90.8 percent).
