がん１０年生存率５８．３％　改善傾向続く―０４～０７年診断・国立がん研

　国立がん研究センターなどの研究班は１９日、２００４～０７年にがんと診断された患者の１０年後の生存率が５８．３％だったと発表した。１０年生存率は改善傾向が続いており、前回調査（０３～０６年に診断）に比べて１．１ポイント上昇した。
　がんの専門医療機関２１施設で診断を受けた１５～９４歳の約９万４０００人について、がん以外の死因の影響を除いて生存率を算出した。
　主な部位別の生存率では、前立腺がんが最も高く９８．８％だった。他は乳がん８６．８％、大腸がん６８．７％、胃がん６６．８％、肺がん３２．４％、肝臓がん１６．１％などで、最も低い膵臓（すいぞう）がんは６．２％だった。（2020/11/19-14:31）

The 10-year survival rate of people in Japan who were diagnosed with cancer in 2004-2007 stood at 58.3 pct, 1.1 percentage points higher compared with such patients in 2003-2006, a research team of entities including the National Cancer Center said Thursday.
   The 10-year cancer survival rate has been on an improving trend in the country.
   The latest figure was calculated based on data covering some 94,000 people aged 15-94 who were diagnosed with cancer at 21 Japanese medical institutions specializing in cancer treatment, excluding the effects of causes of death other than cancer.
   By cancer type, the survival rate was the highest at 98.8 pct for prostate cancer, followed by 86.8 pct for breast cancer, 68.7 pct for bowel cancer, 66.8 pct for stomach cancer, 32.4 pct for lung cancer and 16.1 pct for liver cancer. Pancreatic cancer had the lowest survival rate, at 6.2 pct.
   The research team offered the view that the 10-year survival rate will likely improve further in the future as new cancer treatment methods have been developed since the patients covered by the latest survey were diagnosed with cancer more than 10 years ago.
