New Blood Test Can Quickly Detect Pancreatic Cancer

A new blood test has been developed by researchers that can detect pancreatic cancer in less than an hour, finds study.

Pancreatic cancer can now be rapidly detected in less than an hour with a new blood test developed by US researchers, says a recent study

The test, which is at the proof-of-concept stage, can rapidly screen a drop of blood for biomarkers of pancreatic cancer and provide results in less than an hour.

Pancreatic Cancer - All About the Disease, its Diagnosis and Management
Pancreatic cancer often involves its exocrine part. It grows aggressively, and often detected late. Treatment options include surgery, radiation and chemotherapy.

‘A new electronic chip-based blood test shows promising results in detecting pancreatic cancer quickly.’

"We can use just a drop of blood as is -- no extra processing required," said lead author Jean Lewis, Assistant Project Scientist at UC San Diego.

The test uses an electronic chip-based system to extract nano-sized biological structures called exosomes directly from blood in minutes.

The physicians need to just apply a drop of blood on a small electronic chip, then turn the current on, wait for several minutes and add fluorescent labels and finally look at the results under a microscope.

Dual Thermal Ablation Kills Cancer Cells in Pancreatic Cancer
Dual thermal ablation, heating then freezing, at moderate temperatures offers an effective paradigm for targeting pancreatic cancer cells. New research could lead to improved method of treating pancreatic cancer.

If a blood sample tests positive for pancreatic cancer, bright fluorescent circles will appear, the researchers said, in a paper published in the journal ACS Nano.

"This test could be used as a primary screening strategy to identify patients who would subsequently need to undergo more expensive and invasive diagnostic methods like a CT scan, MRI or endoscopy," added Rebekah White, surgical oncologist and Associate Professor at the university's Moores Cancer Centre.

World Pancreatic Cancer Day 2017: Demand Better. For Patients. For Survival
The World Pancreatic Cancer Day is being celebrated on November 16, 2017, aims to early diagnosis and improve outcomes for the patient.

In the trial, the chip was able to flag the blood samples of patients with pancreatic cancer from those of patients without cancer.

"We envision that in the future, physicians might perform this type of test using a quick finger stick to diagnose patients who may not know they have the disease yet," Lewis added.

New Culprit in Pancreatic Cancer Progression Identified
Gut microbiome was associated with pancreatic cancer progression. Immunotherapy can be effective when microbiome is targeted in pancreatic cancer patients, which can prevent the progression of the disease.
