Sidestepping the Biopsy With New Tools to Spot Cancer

Sidestepping the Biopsy With New Tools to Spot Cancer | Lung Cancer Dispatch | Scoop.it

"For people with cancer or suspected cancer, the biopsy is a necessary evil — an uncomfortable and somewhat risky procedure to extract tissue for diagnosis or analysis.


"Lynn Lewis, a breast cancer patient in Brooklyn, has had her cancer analyzed an easier way: simple blood tests that are being called 'liquid biopsies.'


"Telltale traces of a tumor are often present in the blood. These traces — either intact cancer cells or fragments of tumor DNA — are present in minuscule amounts, but numerous companies are now coming to market with sophisticated tests that can detect and analyze them."

DNA Shed by Tumors Shows Promise for Non-Invasive Screening and Prognosis

DNA Shed by Tumors Shows Promise for Non-Invasive Screening and Prognosis | Lung Cancer Dispatch | Scoop.it

"Certain fragments of DNA shed by tumors into the bloodstream can potentially be used to non-invasively screen for early-stage cancers, monitor responses to treatment and help explain why some cancers are resistant to therapies, according to results of an international study led by Johns Hopkins Kimmel Cancer Center investigators.


"Analyzing blood samples from 640 patients with various cancers, the researchers used digital polymerase chain reaction-based technology (a sophisticated method of multiplying and measuring the number DNA molecules) to evaluate how well the DNA fragments predicted the presence of tumors in the patients."

Quick, Simple Blood Test for Solid Cancers Looks Feasible

Quick, Simple Blood Test for Solid Cancers Looks Feasible | Lung Cancer Dispatch | Scoop.it

"The idea of a general, quick and simple blood test for a diverse range of cancers just came closer to reality with news of a new study published in Nature Medicine.


"Researchers from Stanford University School of Medicine have devised an ultra-sensitive method for finding DNA from cancertumors in the bloodstream.


"Previous research has already shown circulating tumor DNA holds promise as a biomarker for cancer, but existing methods for detecting it are not sufficiently sensitive and do not cover a diverse range of cancers.


"Ways to increase the sensitivity and coverage of such tests exist, but these are cumbersome and time-consuming, and need lots of steps to customize for individual patients, so they are not feasible for use in clinics.


"The new approach promises to change that. It is highly sensitive and specific and should be broadly applicable to a range of cancers, say the researchers."
