British scientists have invented an artificial eye that detects throat cancer

British scientists have developed an artificial eye that can detect early oesophageal cancer, an eye cancer that affects 9,000 Britons a year, most of whom die within 12 months.

  • Doctors use an artificial pair of eyes to check for precancerous cells
  • A flexible tube is inserted when a doctor performs an endoscopy on a patient
  • Every fifth case of esophageal cancer is not detected by doctors in the early stages
  • Symptoms include loss of appetite, difficulty swallowing, and acid reflux

Artificial intelligence could dramatically improve the chance of early prevention of oesophageal cancer, a pioneering NHS program has revealed.

The computer technology works by analyzing images taken during a procedure called an endoscopy, when a small camera at the end of a flexible tube is inserted into the throat, acting as a “second eye” to help doctors detect precancerous lesions. cells in the intestine.

Currently, one in five cases are missed by doctors during routine endoscopy – sometimes with dire consequences. But new test results of artificial intelligence software show that 92 percent of patients can accurately detect early signs of cancer during endoscopy.

Around 9,000 Britons are diagnosed with oesophageal cancer each year.  Patients with the most common form of adenocarcinoma live an average of one year after diagnosis, making it one of the deadliest forms of the disease.

Professor Rehan Heidry, consultant endoscopist at University College London Hospitals NHS Trust, who recommended the procedure, said: ‘If we catch oesophageal cancer early, it can be treated with minimally invasive surgery and patients don’t need surgery or rounds of chemotherapy and radiotherapy.’

Around 9,000 Britons are diagnosed with oesophageal cancer each year. Patients with the most common form of adenocarcinoma live an average of one year after diagnosis, making it one of the deadliest forms of the disease.

Common symptoms include loss of appetite, difficulty swallowing, and acid reflux. Up to 13 percent of patients develop a condition called Barrett’s esophagus – when the cells lining the esophagus change and mutate. The main cause of acid reflux is thought to be stomach acid backing up into the esophagus and damaging these cells. One in ten patients with acid reflux has Barrett’s disease.

In about one in 100 cases each year, the cell changes into a precancerous condition called dysplasia, which later turns into full-blown cancer.

Precancerous cells can be surgically removed in the same endoscopic procedure, using a fine wire passed down the throat to scrape away the mutated cells. Studies show that the procedure is highly effective, and 95 percent of patients are still cancer-free ten years later.

Treatment for full-blooded esophageal cancer involves removing part of the bile. During the operation, incisions are made in the patient’s neck, stomach, or abdomen to remove part or all of the bile and replace it with a portion of the stomach or intestines. But in more than half of these patients, the cancer returns within two to three years.

Advanced disease is treated with a combination of chemotherapy and radiotherapy. If other treatments fail, immunotherapy may be used next.

However, in this case, the cancer is usually incurable – and only 15 percent of patients survive five years or more.

An artificial intelligence program called CADU increases the likelihood of early detection of esophageal cancer by highlighting invisible danger areas in a patient’s throat. As the doctor moves the camera down the patient’s throat, the software analyzes the images the doctor is seeing in real time, generating alerts that flash on the screen and directing the surgeon to the abnormal cells.

The technology has been approved by UK health regulators and has been in use at UCH in London for the past year. Experts believe it will be considered for wider use in NHS hospitals within the next year.

Professor Heydrie said: ‘A man in his 60s recently presented with symptoms of Barrett’s oesophagus. I couldn’t look at the screen during the endoscopy and see any early signs of cancer. But the AI ​​system picked it up right away and highlighted the area.

“After scraping the cells and sending them to the lab, the results came back within a week – and the computer was right. The cells were cancerous.’

Now hopefully the patient is not at risk of developing cancer and Professor Heidry says: ‘Compare this to the treatment of oesophageal cancer today – patients have a major operation to remove part of their oesophagus.

“This will involve spending several weeks in hospital and his recovery could take up to six months.

“With the AI ​​procedure, the risk is minimal and patients can go home the next day.”
