Astronomers And Cancer Researchers Work Together To Fight Cancer
At first glance, astronomers and cancer researchers may not seem to have a lot in common. After all, astronomers spend their time gazing at distant stars and galaxies, while oncologists fight tumors.
But at the University of Cambridge in the UK, astronomers and cancer researchers have joined forces. Specifically, astronomers there repurposed image analysis algorithms they use to spot distant galaxies to help oncologists diagnose aggressive tumors.
Here is How It Works
Astronomers use the algorithms to analyze faint, indistinct images captured by large telescopes. Powerful computers help identify these images as galaxies, stars, planets, and other celestial bodies.
When cancer researchers study tumors, they stain samples to pick out subtle differences that clue them in to what types of proteins a given tumor harbors. Identifying the proteins helps researchers know if a tumor is especially aggressive.
This process typically involves individual scientists peering at tumor samples under microscopes, which is time consuming and laborious. But using reconfigured image analysis algorithms to identify tumor proteins can speed up the process significantly.
Testing The Process
To test the process, the researchers used the adapted algorithms on samples from more than 2,000 breast cancer patients. They found that computer analysis was just as accurate at detecting specific proteins as scientists peering through microscopes. And the computer was much faster.
The researchers plan to further refine the computerized method by testing it on samples from more than 20,000 breast cancer patients.
天文學(xué)家和癌癥研究者共同抗擊癌癥
乍一看，天文學(xué)家和癌癥研究者似乎沒有什么共同點(diǎn)。畢竟，天文學(xué)家致力于觀察遙遠(yuǎn)的星體和星系，而腫瘤學(xué)家則治療腫瘤。
但是，在英國(guó)的劍橋大學(xué)，天文學(xué)家和癌癥研究者已經(jīng)開始合作了。具體來說，天文學(xué)家改進(jìn)了過去曾用于觀測(cè)遙遠(yuǎn)星系的影像分析法，來幫助腫瘤學(xué)家診斷惡性腫瘤。
如何實(shí)現(xiàn)
天文學(xué)家用這種影像分析方法分析由大型望遠(yuǎn)鏡捕捉到的微弱，模糊的星體圖像。強(qiáng)大的計(jì)算機(jī)可以幫助辨認(rèn)這些圖像是星系，恒星，行星還是其它天體。
當(dāng)癌癥研究者研究腫瘤時(shí)，對(duì)樣本染色，進(jìn)而辨別出微小的差異，染色可以顯示出腫瘤樣本的蛋白質(zhì)類型。鑒別蛋白質(zhì)可以幫助研究人員確定腫瘤是否是惡性的。
這一過程通常需要專業(yè)的科學(xué)家在顯微鏡下觀察腫瘤樣本，既費(fèi)時(shí)又費(fèi)力。但是使用改良后的圖像分析方法鑒別腫瘤蛋白質(zhì)，速度就顯著加快了。
程序測(cè)試
為了測(cè)試這種方法，研究人員對(duì)2000多名乳腺癌患者的樣本使用改良后的算法分析。他們發(fā)現(xiàn)，電腦分析和科學(xué)家通過顯微鏡的觀察在鑒別特定蛋白質(zhì)時(shí)同樣精確。而且計(jì)算機(jī)的速度更快。
研究人員計(jì)劃通過測(cè)試20000多名乳腺癌患者樣本，進(jìn)一步改進(jìn)計(jì)算機(jī)算法。
