En hunds nos kunde identifiera lungcancer i utandningsluft i över 95 % av fallen.
En ny studie visar att:
🔷 Fem tränade hundar analyserade 11 900 utandningsprover från 824 personer, varav 111 hade lungcancer.
🔷 När hundarna arbetade var för sig identifierade de lungcancer korrekt i 82–89 % av fallen och markerade sällan personer som inte hade cancer.
🔷 Tillsammans presterade de ännu bättre. När minst tre hundar var överens uppnåddes en träffsäkerhet på 95 %, utan ett enda falskt positivt resultat.
Alltför många får beskedet "lungcancer" först när det är för sent att bota. Ett test som kan upptäcka sjukdomen tidigare är väl värt att införa 🙏
A dog’s nose picked out lung cancer on breath in over 95% of cases.
This is from a new study at Charité in Berlin. Here’s how it worked.
🔷 Five trained dogs went through 11,900 breath samples from 824 people, 111 of whom had lung cancer
🔷 Working alone, each dog got it right 82 to 89% of the time, and rarely flagged someone who did not have cancer
🔷 They did better as a group. A sample only counted if at least three dogs agreed, and on that basis they got past 95%, with no false alarms at all
🔷 This was done in training, not in a real clinic
Too many people only hear the words “lung cancer” once it is already advanced. A test that could pick it up earlier, with no needle and no scan, is worth following.
The researchers want to try it next alongside the screening programmes that already exist.
Most of the people who gave samples were young and healthy, so we do not know yet how the dogs would do with the older, higher risk group that screening is aimed at. The dogs also did better or worse depending on the weather and on who was handling them.
