TUESDAY, Sept. 17 (HealthDay News) -- Nearly 14 million people in the United States, or one in 23, are now cancer survivors.
In comparison, only 3 million people, or one in 69, were cancer survivors in 1971, according to the third annual cancer progress report, issued Tuesday, by the American Association for Cancer Research (AACR).
While there are increasing numbers of cancer patients because some cancers are more common with age, "there is a large increase in the number of survivors," said AACR President Dr. Charles Sawyers. "That's a return on our investment in cancer research."
Sawyers, who chaired the report writing committee, is also an investigator for the Howard Hughes Medical Institute, and chair of the human oncology and pathogenesis program at the Memorial Sloan-Kettering Cancer Center, in New York City.
Other noteworthy advances, Sawyers said, is the approval of 11 new anticancer drugs in the past year alone, which he called "amazing." Also of note is the evolution of immune system modifiers for cancer, such as drugs for certain lymphomas and multiple myeloma, that rev up the immune system to fight the cancer. "Science is paying off, finally," he said.
From 1990 through 2012, more than 1 million lives have been saved from cancer, according to the report.
"The progress is astonishing," said Dr. Cy Stein, a distinguished professor and chair of medical oncology and experimental therapeutics at the City of Hope Comprehensive Cancer Center in Duarte, Calif.
"Things have been getting better. That is the truth of this report," said Stein, who is also deputy director of clinical research at City of Hope. He was not involved in the report.
Among the successes noted in the report are that the five-year survival rates for women diagnosed with invasive breast cancer have increased from 75 percent in the mid-1970s to 90 percent or more now.
For children diagnosed with acute lymphocytic leukemia, the five-year survival rates have increased from 58 percent to 90 percent or greater during the same time period.
But the progress has not been uniform for all cancers. For instance, the five-year survival rates for some cancers, including the aggressive brain cancer known as glioblastoma multiforme, as well as liver, lung and pancreatic cancers, have not improved much over more than 40 years, with survival rates of 4 percent to 16 percent.
