　　Cancer Drug Trials Often Halted Early

　　An increasing number of clinical trials for new cancer treatments are being halted before the risks and benefits have been fully evaluated, say Italian researchers, who warn that this growing trend could put patients at risk of harm from new therapies rushed into use.

　　The researchers looked at 25 randomized, controlled clinical trials that were stopped early because the treatments had started to show benefit to patients.

　　"When we analyzed 25 trials over a 10-year period between 1997 and 2007, we found a consistent increase in prematurely stopped trials -- more than 50 percent were stopped within the last three years," study co-author Giovanni Apolone said at a news conference Tuesday.

　　Of 14 trials halted early and published between 2005 and 2007, the researchers found that 11 (79 percent) of them were used to support drug approval applications submitted to the European Medicines Agency and the U.S. Food and Drug Administration.

　　"This suggests a strong commercial component in stopping trials prematurely. In fact, this strategy could guarantee quicker access to the market for companies. On the other hand, a quicker clinical drug development may lead to an 'immature' benefit/risk balance of new drugs," Apolone said.

　　He and his colleagues "are aware that trials stopped early because they are showing benefit may result in identification of promising new treatments for patients. However, findings obtained following this strategy should be considered to be preliminary results that require subsequent confirmation."

　　It can take several years for the long-term benefits or harmful side effects of a new treatment to become apparent, Apolone noted, but the average duration ( 持續(xù)時(shí)間) of the 25 studies he and his colleagues analyzed was 30 months, with a range from 12 to 64 months.

　　They also found that at the time five of the studies were stopped, they'd enrolled less than 40 percent of the total number of patients planned for final analysis.

　　"Clinical trials need to stop early for superior benefit whenever there's proof beyond reasonable doubt that the new treatment really is superior. That would be an ethical obligation,"

　　Stuart Pocock, a professor of medical statistics at the London School of Hygiene and Tropical Medicine in the United Kingdom, said at the news conference. "However, too many trials are stopped early claiming efficacy (功效) without strong evidence being available."

　　答案與解析：

　　16.A。題干：最近半途而廢的臨床實(shí)驗(yàn)的數(shù)量增加了。利用題干關(guān)鍵詞可以定位到文章第一句：“越來(lái)越多的研究癌癥新療法的臨床實(shí)驗(yàn)中止了……”題干所述與文章信息相符，故選A。

　　17.B。題干：提前停止實(shí)驗(yàn)是因?yàn)橹委煴蛔C明是無(wú)價(jià)值的。利用題干關(guān)鍵詞可以定位到文章第二段：“臨床實(shí)驗(yàn)之所以中止是因?yàn)橹委熼_(kāi)始對(duì)病人見(jiàn)效了。”因此，題干所述與原文不符，故選B。

　　18.C。題干：25個(gè)實(shí)驗(yàn)包括差不多相同數(shù)量的參與者。利用題干關(guān)鍵詞進(jìn)行定位，文章并沒(méi)有提及有關(guān)25個(gè)實(shí)驗(yàn)參與者的數(shù)量情況，所以選C。

　　19.A。題干：有些實(shí)驗(yàn)中止是因?yàn)樯虡I(yè)方面的原因。由關(guān)鍵詞commercial定位到文章第五段：“這意味著中止實(shí)驗(yàn)是有經(jīng)濟(jì)原因的。”題干所述與文章信息相符，因此選A。

　　20.c。題干：當(dāng)實(shí)驗(yàn)中止時(shí)，參與者很高興。文章并沒(méi)有提及有關(guān)參與者的態(tài)度問(wèn)題，因此選C。

　　21.A。題干：有些實(shí)驗(yàn)的時(shí)間太短了，無(wú)法顯示長(zhǎng)久的影響。根據(jù)關(guān)鍵詞long-term定位到第七段：“一種新藥物產(chǎn)生的長(zhǎng)遠(yuǎn)好處和壞處有時(shí)需要很長(zhǎng)時(shí)間才能明了。”題干所述與文章信息相符，所以本題選A。

　　22.B。題干：Stuart Pocock認(rèn)為臨床實(shí)驗(yàn)無(wú)論如何也不能中止。根據(jù)專有名詞Stuart Pocock定位到第九段：“太多實(shí)驗(yàn)停下的時(shí)間太早，其功效并沒(méi)有強(qiáng)有力的佐證，”但Stuart Pocock并沒(méi)有完全否定提前結(jié)束，故本題選擇B。
