[ Cancer ] - Clue Found Resistance Drug

According to researchers "It may be possible to extend the usefulness of cancer drugs by preventing drug resistance in tumours."

Experiments showed the cancerous cells acted like cars in a traffic jam when one route was blocked, they found an alternative. In this case, the tumours replaced the EGFR route with one involving a different protein - ERBB2 - and continued to grow.

Cancer Operation Carried Out By Robot

Surgeons are testing a multimillion-pound robot that could significantly help to reduce the risk of bowel cancer returning. The robot should make it easier to remove tumors without leaving behind abnormal cells. Just one cell can form a new cancer. Surgeons watch magnified 3D pictures of the operation and have precise, rock-steady control of the instruments.

The University of Leeds is leading a worldwide trial, comparing the robot against standard keyhole techniques for removing bowel cancer.

Reducing recurrences by optimum surgery is really important. It ultimately saves money on expensive new drug treatments, and prevents pain and anguish for our patients.

Phil Quirke, professor of pathology at the University of Leeds Consultant surgeon David Jayne explained that it is crucial to prove that new technology improves the quality of care.

"Not only do we have to do it safely for the patient, we have to think long term," he said.
"We have to take the cancer out in its entirety and do not want the disease coming back. We hope the accuracy of the robot will help us to do that."

Robots have been rapidly introduced into the NHS without proof that they are worth their £1m price tag.

Scientists at the university closely examine the tumours removed by both traditional keyhole techniques and with robotic assistance.

Chris Garbett had his cancer removed by the robot

Computer monitors with 50 million pixels allow them to see in fine detail whether the surgeon has left a sufficient safety margin when cutting out the cancer.

Professor of pathology at University of Leeds, Phil Quirke, told Sky News: "If they can do it more consistently than they can with keyhole surgery then we should be moving towards using the robot. "Reducing recurrences by optimum surgery is really important. It ultimately saves money on expensive new drug treatments, and prevents pain and anguish for our patients."

The study will involve 400 patients across Europe, the US and Asia. Chris Garbett had his cancer removed by the robot. It is too soon to know whether it will return, but he has already seen other benefits. He said: "I think the robot technique aided my recovery. I spent less time in hospital and was up and about within a week of the operation."
