An accurate, convenient, environmentally friendly and easy-to-use diagnostic tool for several tumorsincluding those of the pancreas, stomach, and colorectal, was reported in one study published in Nature Sustainability.
The importance of an accurate diagnosis in tumors
The tool can diagnose i
tumors in minutes and could help address the need for accessible diagnostic tools, especially in remote areas.
Over a billion people worldwide experience a high rate of missed disease diagnoses: the World Health Organization estimates that less than 30% of low-income countries have access to generally available diagnostic facilities.
An estimated 70% of cancer-related deaths worldwide occur in low- and middle-income countries, demonstrating the need for accurate and affordable testing. Additionally, testing may be used in ecologically sensitive or energy-constrained regions, and solutions are needed to ensure sustainable options are available.
Kun Qian and colleagues developed a tumor diagnostic method based on the detection of metabolites. Using dried serum stains, instead of traditional liquid blood storage, this instrument provides an environmentally friendly and metabolite-stable solution for the collection and preservation of biological specimens.
They combined this with nanoparticle-enhanced mass spectrometry, which improved sensitivity and speed of detection. Qian and colleagues indicate that this approach enables the diagnosis of pancreatic, gastric, and colorectal cancers in minutes, offering convenience, environmental friendliness, serum-equivalent precision, and an easy-to-use protocol.
Collaborating with population-based cancer screening programs, the authors suggest that implementing this tool in less developed regions could reduce missed diagnoses of colorectal cancer, gastric cancer, and pancreatic cancer by 20.35%-55 ,10%.
This technology could offer greater accessibility and precision and maximize health gains within available resources, the authors conclude.
