Your canine friend, dog uses its highly evolved sense of smell to pick out blood samples from people with cancer with almost 97 per cent accuracy, a finding that can lead to new low-cost and non-invasive screening approaches for the disease, finds a study.

Dogs have smell receptors 10,000 times more accurate than humans’, making them highly sensitive to odours we can not perceive.

“Although there is no cure for cancer, early detection offers the best hope,” said lead researcher Heather Junqueira, at BioScentDx, a US-based healthcare company. “A highly sensitive test for detecting cancer could save thousands of lives and change the way the disease is treated,” he said.

For the study, the team used a form of clicker training to teach four beagles to distinguish between normal blood serum and samples from patients with malignant lung cancer.

The results showed that the pups' attractiveness was lowest at birth and increased to a maximum before 10 weeks of age before declining and then levelling off.

Although one beagle — aptly named Snuggles — was unmotivated to perform, the other three correctly identified lung cancer samples 96.7 per cent times and normal samples 97.5 per cent times.

“This work is very exciting because it paves the way for further research along two paths, both of which could lead to new cancer-detection tools,” said Junqueira.

“One is using canine scent detection as a screening method for cancers, and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds,” he said.

The results will be presented at the American Society for Biochemistry and Molecular Biology annual meeting in Florida. The team plans to use canine scent detection to develop a non-invasive way of screening for cancer and other life-threatening diseases. (IANS)

Indraprastha Apollo Hospital in New Delhi on Friday launched the most advanced version of TomoTherapy Radixact X9– the smartest radiation therapy to treat the most complicated cancer tumours.

Tomotherapy comes as a boon for cancer treatment since it has a higher degree of precision, speed and accuracy.

Patients find it more comfortable to be treated under this technology owing to the rotational helical mechanism, also the set-up time is lesser as compared to other therapies.

“The launch of the most advanced version of the Tomotherapy technology is truly a remarkable development in the field of Radiation Oncology. This will be a revolutionary step in the treatment of cancer. With this system we can deliver both fractionated radiotherapy as well as SBRT and Radiosurgery,” said Suneeta Reddy, Managing Director, Apollo Hospitals Group.

“The new generation radiation machine and our highly experienced team enables us to move ahead towards precise and personalised care, therefore improving the quality of life of cancer patients and ensure better clinical outcomes,” Reddy added.

Tomotherapy is effective in treating cancer, irrespective of the stage, especially multiple metastasis. The best outcomes are for treatment of bilateral breast cancer, paediatric oncology and all other forms of cancer.

“We are taking precision and excellence to the next level with the revolutionary Radixact-X9: Tomotherapy, system powered by state-of-the-art 3D CT imaging. It uses a linear accelerator to deliver high-dose radiation to the tumour with sub-millimetre precision,” said P ShivaKumar, Managing Director, Indraprastha Apollo Hospitals.
