大問1

 Toward better control of colorectal cancer

 “There is so much in life we can't control. But here's something we can: colorectal cancer”, said Academy Award winning actress Meryl Streep in the USA's Screen for Life: National Colorectal Cancer Action Campaign. Her comment on colorectal cancer might not be entirely accurate, but it has some merit with regard to prevention of this disease. As discussed in a Seminar by Hermann Brenner and colleagues in today's Lancet, colorectal cancer offers much better opportunities for secondary prevention by early detection and screening than do most other cancers.


 Worldwide, colorectal cancer is the third most common cancer and fourth leading cause of death from cancer. Most cases develop slowly over many years from adenoma to carcinoma, and the precursor lesion—adenoma—can be readily detected and removed. Hence, the disease is an ideal target for early detection and prevention by screening. Consistent evidence has shown that colorectal screening reduces colorectal cancer incidence and mortality, and is cost effective. Furthermore, guidelines already endorse several screening strategies, including faecal occult blood tests, flexible sigmoidoscopy, and optical colonoscopy.


 Despite the supporting evidence, recommendations, and availability of screening tests, the uptake of screening of colorectal cancer is disappointingly low in most countries, even in developed regions of the world. In England, recent figures stated that among the eligible 60—74-year-old age group only 58% were screened for colorectal cancer. Similarly, in the USA, only about 61% of adults aged 50 years and older get screened for colorectal cancer. The situation in developing countries is even more worrying. By contrast with decreasing trends for the incidence and mortality of colorectal cancer in many developed countries like the USA, the incidence and mortality in several developing countries and in previously low-risk countries, such as China, have continued to increase. This trend is related to their transition towards a so-called westernised lifestyle such as the consumption of high-fat diets and physical inactivity, people's reluctance to participate in cancer screening, and relatively poorer health-care resources.


 Several barriers to the uptake of colorectal cancer screening exist. In China, traditional cultural beliefs, such as the perception that both primary and secondary prevention of cancer are threatening to the harmonious state of health and unnecessary, present a substantial obstacle to participation in cancer screening. Worldwide, the unpleasantness and embarrassment of procedures are major concerns, especially for sigmoidoscopy and colonoscopy because of their invasive nature. In terms of patient education, both respected society websites and popular online patient information sites on colorectal cancer are too complex for many lay people to understand, according to a study published in Gastrointestinal Endoscopy by Chenlu Tian and colleagues at the University of Texas Southwestern Medical Center, TX, USA, and they do not address the appropriate risks, concerns of patients, or barriers to screening. Furthermore, huge disparities exist in colorectal cancer testing; there is low uptake in groups with lower socioeconomic status, which could exacerbate existing inequalities in overall colorectal cancer mortality.


 How can the uptake of colorectal cancer screening be improved? A variety of innovative methods are discussed in the Seminar. Less invasive approaches such as alternative imaging technologies, as well as non-invasive blood and stool-based screening tests have broadened screening choices. Encouragingly, the analysis of stool DNA to identify tumour-specific changes has become more sensitive and promising against the backdrop of rapid progression in molecular diagnostics of the disease. Secondly, the development of organised screening programmes, involving personal invitations, population monitoring of screening rates, and quality assurance, is emphasised. By contrast with opportunistic screening, which might be offered to people who are being examined for other reasons, organised screening holds the promise of uniformly delivered screening services to all eligible members of a population. Thirdly, screening strategies should take the social determinants of health and the heterogeneous culture of different groups of individuals into consideration.


 Although highly effective new approaches offer the potential to reduce the incidence of colorectal cancer, there are still pervasive sociodemographic inequalities in screening. Therefore, colorectal cancer screening programmes must be, first and foremost, designed and implemented so that they are understandable and accessible to all eligible people, irrespective of their sociodemographic characteristics.

大問2

 Me Too!

 The first great era of drug discovery, then, which stretched roughly from 1935 to the mid-1960s, could also be called the era of molecular modification. Once a researcher—often in the public sector—identified a new chemical class that was effective against a disease state, every major drug company put chemists to work coming up with their own versions that could do roughly the same thing. “The great drug therapy era was marked not only by the introduction of new drugs in great profusion and by the launching of large promotional campaigns but also by the introduction of what are known as ‘duplicative’ or ‘me-too’ products,” noted pharmacologist Milton Silverman and physician Philip R. Lee of the University of California at San Francisco. Surveying the drug scene in the early 1970s, they counted more than 200 sulfa drugs, more than 270 antibiotics, 130 antihistamines, and nearly 100 major and minor tranquilizers. Most of the new drugs “offer the physician and his patient no significant clinical advantages but are different enough to win a patent and then be marketed, usually at the identical price of the parent product, or even at a higher price.”[7] The biotechnology revolution of the late 1970s and 1980s and the NIH-funded explosion of knowledge about cellular interactions set off a second wave of drug innovation. Drawing from the government's vast investment in biomedical research since the end of World War II, medical researchers promised unique cures for the chronic diseases that had become the leading causes of death: heart disease, cancer, diabetes, and dementia. Cover stories in the nation's popular magazines and newspapers heralded the exploits of scientific medicine, often focusing on the drug companies that were bringing the new products to market. No longer would the drug industry focus on developing and marketing me-too drugs that did little more than cloud physicians' judgments and crowd pharmacists' shelves. A new era of miracle drugs was at hand, the companies' press releases suggested.

 

 Progress on delivering on those promises was slow, however. A handful of the new biotechnology products, such as erythropoietin, human growth, and blood clotting factors, which hit the market in the first decade after biotechnology's emergence, certainly were unique. Physicians for the first time were able to replace or enhance patients' supplies of naturally occurring proteins by injecting artificial versions.

 

 The handful of genetically engineered medicines that emerged in the first two decades of the biotechnology revolution were also unique in an economic sense. In 1980 the Supreme Court in Diamond v. Chakrabarty liberalized the nation's intellectual property laws by allowing the patenting of living things. (The case involved a patent on an oil-eating bacteria.) The young start-up companies that manufactured the proteins were now able to protect themselves against me-too competition by surrounding their inventions with gene and gene-process patents. For this new class of medicines, companies no longer had to rely on marketing and cartel-like behavior to ensure against a sharp decline in prices due to competition from me-too drugs. They could rely on the exclusivity granted by patent law. There would be only one genetically engineered version of a therapeutic protein.

説明:

 出典ソース本文はかなりの長文ですが、本文から一部を抜粋しての問題でした。今回のブログで抜粋した部分が当日の問題部分にぴったり当てはまるかは正直記憶が曖昧でわかりません。勉強用に出典ソース全体に目を通しておくのが良いと思います。

 こちらも下線部分の英語を日本語で回答する記述式の問題です。240字程度でまとめる必要があったと思います。

 me too drugの問題点や改善策についての問いだったと思います。

 

小論Ⅰ、小論Ⅱ共に、英語の長文読解能力は必須なので、編入試験にはこの程度の英語は必要だという良い資料になるのではないでしょうか。
