New blood test can detect more than 50 types of cancer, many of which are difficult to detect early – .


The earlier most cancers are discovered, the better the chance that they will be treated successfully.
The Mayo Clinic participated in the search for a test capable of detecting more than 50 cancers. Doctors call it a game changer, reports CBS Minnesota.

“My dad was a healthy guy. He had no known risk factors for cancer, ”said Dr Julia Feygin. Feygin lost her 40-year-old father to pancreatic cancer when she was 13. Diagnosed at stage three, he lived nine months longer.

“I firmly believe that this goal can be found in whatever is going on,” said Feygin.

She is now part of a team from a company based in Menlo Park, Calif. Called GRAIL, which is introducing the blood test, called Galleri. She says he can catch hard-to-detect, aggressive and often fatal cancers like the pancreas, ovary and esophagus.

“If cancers can be detected early, we can dramatically improve patient outcomes,” said Feygin.

Feygin explains that our blood contains a DNA signature. The blood test tracks the DNA of a cancer cell.

Two tubes of blood are taken and sent to the GRAIL laboratory for analysis.

“We can find and sequence these tiny pieces of tumor-derived DNA in the blood, and based on the patterns we see, we can reveal if there is a signal for cancer present. We can predict with great precision where in the body this cancer signal is coming from, ”said Feygin.

Results are returned to the healthcare provider within 10 business days.

An interventional study that included the Mayo Clinic with 6,600 participants returned 29 signals that were followed by a cancer diagnosis.

Another study found a false positive rate of less than 1%.

There are a few caveats about who can take the test.

“It is intended for use by people at high risk for cancer. It can be something as simple as age, ”Feygin said.

Currently, the test is done by prescription only. Insurance does not cover it. You would pay out of pocket with a current cost of $ 949.

“In 2021, it is way beyond anything we have been able to do. It is a game changer, ”said Dr Greg Plotnikoff.

He ordered the test for patients and their family members with risk factors, saying cancers detected early are at more treatable stages.

“If we can catch things earlier then we have a chance to make a significant difference,” Plotnikoff said.

He also chose to project himself, since he is over 60 years old.

“If there was any signal, I wanted to know it and be able to do something about it,” Plotnikoff said.

The American Cancer Society says 71% of cancer deaths come from types of cancer for which no screening is recommended.

Feygin says they hope to change outcomes for families like hers in the future.

“This really presents an unprecedented opportunity to bend the cancer mortality curve and really save so many lives,” said Feygin.

According to GRAIL, Galleri “is intended to complement, not replace, cancer screening recommended by US guidelines.”

GRAIL is still working on full FDA approval. You can ask your doctor to order the test.

Before the end of the year, Galleri will be available at Mayo Clinic locations in Rochester, Minnesota, Jacksonville, Florida, and Phoenix. It will also be available at the Mayo Clinic Health System sites in southern Minnesota and Wisconsin.
