AI boosting medical research in battle with cancer

PORT MORESBY: Artificial Intelligence (AI) technology has boosted medical research and discoveries in the centuries of human battle with the dreaded disease - cancer.

Of the 270,000 breast cancers diagnosed in 2018, about 13,500 to 27,000 were attributed to the so-called BRCA mutations, and thus could be targeted with PARP inhibitors, the researchers said.

Using computer simulation analysis, they identified as many as 54,000 more with normal BRCA genes that had defects in homologous repair, and might be treated with the new cancer drugs.

Using artificial intelligence to pinpoint tumour cells with reduced ability to repair their own DNA can help identify tens of thousands of patients who would benefit from treatment with drugs from AstraZeneca Plc and GlaxoSmithKline Plc, researchers said.

Analysing genetic tests with a machine-learning algorithm helps target cancers that are vulnerable to treatment with drugs called PARP inhibitors, according to a study from scientists at Harvard Medical School in Boston and the UK’s University of Cambridge.

Oncology is among the fastest-growing fields in the pharmaceutical industry, with an armada of newly developed treatments sending annual sales surging to about US$133bil (RM547.33bil). Doctors and scientists are searching for more hints of how to deploy the costly drugs that sometimes shrink tumours in just a fraction of patients.

Oncologists often determine whether patients will receive PARP inhibitors like Astra’s Lynparza or Glaxo’s Zejula by testing for flaws in certain gene mutations that block cells from fixing their own DNA using a specific mechanism. Yet many tumours without those mutations may also have the same genetic repair deficit, but are harder to find because there’s no specific gene test.

Analysts estimate Lynparza sales of US$1.1bil (RM4.52bil) this year, and Zejula sales of US$314mil (RM1.29bil). Clovis Oncology Inc’s Rubraca, another PARP inhibitor, is estimated to sell US$147mil (RM604.94mil). – Bloomberg/The Star

News that matter in Papua New Guinea Growing unemployment rate in Papua New Guinea (Employment stagnant since 2014) PORT MORESBY: Employment in Papua New Guinea (PNG) has remained stagnant since 2014 with millions of unemployed looking for jobs. The formal job market currently can only accommodate between 400,000 and 500,000, Institute of National Affairs executive director Paul Barker says. “As more young people enter the job market this year after graduating from tertiary institutions and schools, the chances of securing formal employment is slim. “Employment had remained stagnant despite the increase in potential workers coming out of educations institutions,” he added.

News that matter in Papua New Guinea Sorcery tortures and violence are still being practised in Papua New Guinea in this 21st Century digital era. Sorcery shame for Papua New Guinea in X’mas PORT MORESBY: It was international shame for Papua New Guinea (PNG) this Christmas when sorcery reared its ugly head. Six women were stripped, bound to poles and burnt with hot knives as they screamed in pain, watched by an unsympathetic crowd. In a video that has gone viral in the internet, the women were accused of practising sorcery in Southern’s Enga. Police Comm David Manning described the sorcery torture as vile, inhumane, uncivilised, void of any human decency. “Papua New Guinea cannot progress without letting go of these horrific traditional beliefs. We have launched an urgent probe into the incident in Aiya’s Pawayamo village in Kagua-Erave.” The news break was published by The National : Horror torture of women Decem
