IITians turn to Ar­ti­fi­cial In­tel­li­gence for iden­ti­fy­ing cancer

BioSpectrum (India) - - SCIENCE NEWS -

A team of ex­perts from IIT-Kharag­pur and Tata Med­i­cal Cen­tre, Kolkata, has de­vised a com­puter-as­sisted model. They say it can au­to­mat­i­cally grade breast cancer ag­gres­sive­ness, even in re­mote set­tings, pro­vid­ing fresh im­pe­tus to Ar­ti­fi­cial In­tel­li­gence (AI)based med­i­cal tech­nol­ogy in In­dia. It also seeks to re­duce hu­man er­ror in iden­ti­fy­ing breast cancer of var­i­ous lev­els of ag­gres­sive­ness to as­sist in dis­tin­guish­ing nor­mal and low and higher risk ma­lig­nant tu­mours. The team has tapped into deep learn­ing, a form of AI con­cerned with al­go­rithms in­spired by the struc­ture and func­tion of the brain called ar­ti­fi­cial neu­ral net­works. The ap­pli­ca­tion re­volves around a pro­tein (or marker) called Ki67 which is used to cal­cu­late an in­dex that groups can­cers in the "low" or "high" ag­gres­sive­ness groups. The next phase of the study is val­i­da­tion. The clin­i­cians and the pathol­o­gists are go­ing to re­cruit pa­tients and the re­searchers will treat them de­pend­ing on what the pathol­o­gists say. The results from the soft­ware will be tal­lied as well as from the pathol­o­gists, so the dis­cor­dant rates are pretty low. Then the process will be re­leased for clin­i­cal use.
