癌癥研究中大數(shù)據(jù)能做的五件事
1. 幫助指導(dǎo)使用已通過的癌癥藥物
雖然臨床試驗(yàn)為醫(yī)生們提供了許多藥物如何發(fā)揮作用的有用信息,但是大概只有2%的癌癥患者參與了臨床試驗(yàn)。 事實(shí)上,每天都有成千上萬(wàn)的患者接受診斷和治療。這意味著其實(shí)我們可以從中獲得大量的重要數(shù)據(jù),來(lái)幫助醫(yī)生與病人在面對(duì)不同治療方案及其可能的結(jié)果時(shí)做出更好的選擇。
美國(guó)臨床腫瘤學(xué)會(huì)ASCO發(fā)起建立一個(gè)數(shù)據(jù)庫(kù):CancerLinQ,旨在獲取這些數(shù)據(jù)。它能將數(shù)據(jù)提供給醫(yī)生們, 為他們提供實(shí)時(shí)的治療建議。美國(guó)基因泰克公司(Genentech)的科學(xué)家和醫(yī)生們都對(duì)能幫助ASCO開發(fā)一個(gè)完善的CancerLinQ系統(tǒng)感到興奮。
2. 決定每位患者的預(yù)后治療
了解患者的預(yù)后,可以幫助醫(yī)療團(tuán)隊(duì)決定對(duì)患者癌癥的治療強(qiáng)度,以及在腫瘤消失后需采取的措施。大數(shù)據(jù)正在借助分析從大量不同患者搜集過來(lái)的海量信息,來(lái)預(yù)測(cè)長(zhǎng)期結(jié)果。例如,醫(yī)生可以使用這些信息來(lái)決定哪些患者應(yīng)該接受進(jìn)一步治療,哪些患者,由于他們的癌癥不太可能復(fù)發(fā)而避免不必要的治療。
3. 幫助藥物開發(fā)發(fā)掘潛在的新靶點(diǎn)
對(duì)大量腫瘤DNA進(jìn)行測(cè)序可以幫助研究人員了解一些與癌癥相關(guān)的基因變化。科學(xué)家利用這一點(diǎn)幫助測(cè)試潛在的新藥物,這些藥物能靶定到某些與腫瘤生長(zhǎng)相關(guān)的基因變化或驅(qū)動(dòng)因子。大數(shù)據(jù)可以從臨床前試驗(yàn)中獲得,并用來(lái)幫助藥物或藥物組合的選擇,以放到人類臨床試驗(yàn)的研究中。
4. 解決大的公共衛(wèi)生問題
流行病學(xué)研究包括癌癥在內(nèi)的人類疾病的起因及模式。在大數(shù)據(jù)時(shí)代之前,人們發(fā)現(xiàn)吸煙是導(dǎo)致絕大多數(shù)肺癌的因素?,F(xiàn)在,大數(shù)據(jù)可以幫助解決癌癥研究中更大的問題。新時(shí)代的流行病學(xué)借助于海量的住院記錄及基因組數(shù)據(jù),深入研究不同人群中的不同癌癥。
5. 允許病人直接參與進(jìn)來(lái)
癌癥患者現(xiàn)在可以通過提供基因,醫(yī)療記錄及治療效果等數(shù)據(jù),直接參與癌癥研究。這些信息用于建立大型的研究數(shù)據(jù)庫(kù)。

5 things Big Data CAN do in cancer research
1. Help Guide the Use of Approved Cancer Medicines
While clinical trials provide valuable information to doctors on how medicines may work, only about 2% of people with cancer participate in clinical trials. However, thousands of people are diagnosed and treated every day, which means there is a huge amount of important data that could be obtained to help doctors and patients make better decisions about treatment options and potential outcomes.
ASCO has started an initiative, CancerLinQ, to try to capture some of these data. CancerLinQ is a system that connects doctors with data, helping to inform decisions about treatments in real time. Scientists and doctors at Genentech are excited to help ASCO develop the full CancerLinQ system.
2. Determine an Individual Patient’s Prognosis
Knowing a patient’s prognosis allows medical teams to decide how aggressively to treat each cancer and what steps to take after a tumor is gone. By analyzing information from incredibly large and diverse groups of patients, big data is helping to predict long-term outcomes. For example, doctors can use this information to determine who should receive additional treatment and who might avoid it because their cancer is unlikely to recur.
3. Help Discover Potential New Targets for Drug Discovery
The ability to sequence the DNA of large numbers of tumors has allowed researchers to understand the genetic changes underlying certain cancers. Scientists can use this information to help test potential new medicines that might target some of these genetic changes or drivers of cancer growth. Big data sets from preclinical studies are being used to help predict which medicines or combinations of medicines might be good candidates to move forward into clinical trials in humans.
4. Answer Big Public Health Questions
Epidemiologists study the causes and patterns of human diseases including cancer. In the era before big data, they discovered that smoking causes the vast majority of lung cancer cases. Now big data is allowing them to answer even bigger questions in cancer research. This new era of epidemiology takes advantage of the availability of large collections of hospital records and genomic data, leading to new insights into diverse cancers in diverse populations.
5. Allow Individuals to Get Involved
People with cancer can now play a direct role in research by contributing genetic data and information about their health and how treatments have affected them to large databases used for research.
