Why the appendix might not be so useless after all

Long considered an unnecessary organ, the appendix is now the focus of several studies that aim to better understand its role. Present in many mammals, including humans, it appears to have developed at least 16 times over the course of the evolutionary history of mammals, suggesting that its function must confer a positive selective advantage on those that have it. A new study carried out by…

Detecting oesophageal cancer with AI

Experts at University College London (UCL) and spinout company Odin Vision working with clinicians at UCLH have used artificial intelligence (AI) to help detect early signs of oesophageal cancer. The first procedure in the world using the AI technology was performed at University College Hospital by UCLH consultant gastroenterologist Dr Rehan Haidry. The system, called CADU, uses AI to support…

AI could improve outcomes for bowel cancer patients

A test which uses artificial intelligence (AI) to measure proteins present in some patients with advanced bowel cancer could hold the key to more targeted treatment, according to new research. A team at the University of Leeds collaborated with researchers at Roche Diagnostics to develop the technique, which will help doctors and patients to decide on the best treatment options.

Lung cancer: Tailoring radiation therapy to reduce complications

For many patients with localized lung cancer (non-small-cell lung carcinoma and small cell lung carcinoma), high-dose radiation with concurrent chemotherapy is a potential cure. Yet this treatment can cause severe, acute inflammation of the esophagus (esophagitis) in about one in five patients, requiring hospitalization and placement of a feeding tube. A team of radiation oncologists at Mass…

Research sheds new light on pancreatic cancer metastasis

With an overall survival rate of 9% for those diagnosed, pancreatic cancer remains exceedingly difficult to treat. However, the patient's primary tumor typically isn't what leads to death - it is the cancer's ability to evade detection and metastasize to other organs. A team of researchers at the College of Medicine at the University of Oklahoma has published a new study in the journal…

A new approach for treating bile duct cancer

Intrahepatic cholangiocarcinoma (ICC) develops within the liver. With one to two cases per 100,000 inhabitants in Germany, ICC is one of the rare diseases overall, but it is the second most common liver cancer. The aggressive bile duct tumour remains clinically inconspicuous for a long time, so that it is often only detected late. Because the tumour also only responds to chemotherapy to a limited…

Capsule cameras to test for cancer and diseases

Miniature cameras which patients can swallow to get checked for cancer are being trialled across the NHS. The imaging technology, in a capsule no bigger than a pill, can provide a diagnosis within hours. Known as a colon capsule endoscopy, the cameras are the latest NHS innovation to help patients access cancer checks at home. Traditional endoscopies mean patients need to attend hospital and have…

'Organs-on-a-chip' system sheds light on interactions between gut and brain

In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals such as mice is difficult to do, because their…
