Resultados instantáneos y métodos poco invasivos en la detección del cáncer oral, es la propuesta de este nanobiochip, capaz de detectar células cancerígenas con un 97% de precisión en sus diagnósticos. La prueba es completamente indolora y el paciente no se expone al dolor de la biopsia. El reporte (en inglés) nos llega de WorldDental

Oral Cancer Detection Methods via Nanobiochip

Oral cancer detection methods are now expanding thanks to the creation of a nanobiochip. This new chip is capable of examining specimens collected from biopsies of oral cancer lesions.
The chip can detect cancer cells with a very good success rate and it is as accurate as measures that are more invasive.
The oral cancer nanobiochip has a 97 percent sensitivity as well as a 93 percent specificity when detecting what patients had oral cancers that are premalignant and malignant.
Researchers from the Rice University have created the noninvasive technique. With oral cancer affecting some 300,000 individuals annually, this chip can prove beneficial to many people. In the United States more than 35,000 people are diagnosed with oral cancer every year.
At present, the rate of survival after five years is right around sixty percent, but if the cancer is found very early the person’s chance of surviving is increased up to 90 percent.
With this new nanobiochip there is no waiting days on end for results. The chip can give near instantaneous results as it offers information in as little as fifteen minutes. This can alleviate the amount of time a person spends worrying if he or she has oral cancer or not.
The chip is non invasive and instead of being faced with having a pain inducing biopsy the patient’s lesion is lightly brushed with an instrument that looks very much like a standard toothbrush. The testing is far more humane, with no pain involved, and the faster results means that treatment can be implemented in the fastest time possible.
This new chip is still undergoing testing and tests will be conducted in Texas on 500 more individuals. Testing will also occur in the United Kingdom. If trials go well the team will look to getting the FDA to approve the device for use; this means that dentists could be using the tool in roughly two to five years from now.
The novel invention could eventually increase the number of people that survive oral cancer and it can dramatically reduce patient suffering and anxiety.
