美國(guó)癌癥學(xué)會(huì)發(fā)布的最新數(shù)據(jù)顯示,，自1990年以來,，美國(guó)在預(yù)防和治療癌癥方面成績(jī)顯著,，癌癥死亡率明顯下降。
美國(guó)癌癥學(xué)會(huì)認(rèn)為,，美國(guó)在抗癌方面取得成績(jī)主要應(yīng)歸功于3大舉措：戒煙行動(dòng)使得吸煙人數(shù)減少,、癌癥檢查日趨普遍、癌癥治療手段不斷提高,。
研究人員對(duì)美國(guó)在1970年至2006年間的癌癥相關(guān)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析發(fā)現(xiàn),，美國(guó)的癌癥死亡率經(jīng)歷了先升后降的過程：1970年時(shí)每10萬人中有249．3人死于癌癥；到1990年上升到每10萬人中279．8人,；而到2006年則下降到每10萬人中221．1人,，比1990年時(shí)下降了21％。
研究人員在最新一期網(wǎng)絡(luò)科學(xué)期刊《第一科學(xué)公共圖書館》（PLoS One ）上發(fā)表報(bào)告說,，上世紀(jì)70年代初期美國(guó)發(fā)起“向癌癥開戰(zhàn)”活動(dòng),，幾十年來,，美國(guó)在抗癌方面取得了顯著成效。但他們同時(shí)指出,，美國(guó)并不能因此放松在抗癌方面的努力,，還應(yīng)在癌癥防治和研究領(lǐng)域持續(xù)加大資金投入，以進(jìn)一步降低癌癥死亡率,。(生物谷Bioon.com)

Background
The success of the “war on cancer” initiated in 1971 continues to be debated, with trends in cancer mortality variably presented as evidence of progress or failure. We examined temporal trends in death rates from all-cancer and the 19 most common cancers in the United States from 1970–2006.
Methodology/Principal Findings
We analyzed trends in age-standardized death rates (per 100,000) for all cancers combined, the four most common cancers, and 15 other sites from 1970–2006 in the United States using joinpoint regression model. The age-standardized death rate for all-cancers combined in men increased from 249.3 in 1970 to 279.8 in 1990, and then decreased to 221.1 in 2006, yielding a net decline of 21% and 11% from the 1990 and 1970 rates, respectively. Similarly, the all-cancer death rate in women increased from 163.0 in 1970 to 175.3 in 1991 and then decreased to 153.7 in 2006, a net decline of 12% and 6% from the 1991 and 1970 rates, respectively. These decreases since 1990/91 translate to preventing of 561,400 cancer deaths in men and 205,700 deaths in women. The decrease in death rates from all-cancers involved all ages and racial/ethnic groups. Death rates decreased for 15 of the 19 cancer sites, including the four major cancers, with lung, colorectum and prostate cancers in men and breast and colorectum cancers in women.
Conclusions/Significance
Progress in reducing cancer death rates is evident whether measured against baseline rates in 1970 or in 1990. The downturn in cancer death rates since 1990 result mostly from reductions in tobacco use, increased screening allowing early detection of several cancers, and modest to large improvements in treatment for specific cancers. Continued and increased investment in cancer prevention and control, access to high quality health care, and research could accelerate this progress.
