Liquid Biopsies For Earlier Ovarian Cancer Tracking

The Talcum Powder Lawsuit Helpline continues in one of  it’s missions  to offer the latest news regarding ovarian cancer. We receive dozens of calls on a daily basis from women who feel their use of Talcum Powder products has resulted in their ovarian cancer diagnosis. We continue to connect women with qualified talcum powder ovarian cancer lawyers and offer news we feel will be helpful to these women.

We found this latest news online and hope it will be helpful to our followers.

There is new news about  liquid biopsies offering  hope for earlier treatment and  better tracking of ovarian cancer.

A promising new way to monitor and treat recurrence of ovarian cancer has been identified by researchers a hard-to-detect disease that claims many lives. New research finds liquid biopsies from blood tests and DNA sequencing can detect a return of ovarian cancer long before a tumor reappears.

If you have used Talcum Powder products and suspect an ovarian cancer this may be an option to check out with your doctor.

Researchers at the Mayo Clinic Center for Individualized Medicine have found a promising new way to monitor and treat recurrence of ovarian cancer — a hard-to-detect disease that claims many lives. New research from George Vasmatzis, Ph.D., of the Department of Laboratory Medicine and Pathology at Mayo Clinic, finds liquid biopsies from blood tests and DNA sequencing can detect a return of ovarian cancer long before a tumor reappears. That could lead to earlier intervention and more effective, individualized treatment. Dr. Vasmatzis’ research on the “Quantification of Somatic Chromosomal Rearrangements in Circulating Cell-free DNA From Ovarian Cancers” is published in the July 20 edition of Scientific Reports.

“With liquid biopsies, we don’t have to wait for tumor growth to get a DNA sample,” says Dr. Vasmatzis. “This important discovery makes it possible for us detect recurrence of the disease earlier than other diagnostic methods. We can repeat liquid biopsies to monitor the progression of the cancer. That gives hope of a better treatment plan over time.”

The study was done on 10 patients in advanced stages of ovarian cancer. Blood was drawn before and after surgery. Investigators compared DNA from the liquid blood biopsies to DNA tissue samples from the tumor, using mate-pair sequencing — an inexpensive whole exome sequencing that can reveal genetic changes that contribute to tumor growth.

“In this study, the blood drawn before and after surgery and the surgical tissue was used to identify DNA fragments with abnormal junctions that can only be seen in this patient’s tumor DNA,” explains Dr. Vasmatzis. “Next-generation mate-pair sequencing was used to identify specific DNA changes of the tumor to create an individualized monitoring panel for liquid biopsy. This allows us to shape treatment to the individual patient rather than using a standard treatment that may not work for everyone.”

When post-surgery DNA matched that of the tumor, patients were later found to have had a recurrence of ovarian cancer. However, when the post-surgery DNA did not match the DNA of the tumor, patients were found to be in remission.

Ovarian cancer has one of the highest death rates of all gynecological cancers, because the tumor often cannot be detected until the late stages. Most patients go into remission after initial treatment, but the tumor returns 75 percent of the time. The next stage of ovarian cancer that develops typically does not respond to chemotherapy. More than 21,000 women in the U.S. were diagnosed with ovarian cancer, and 14,000 women died of the disease in 2015.

We wonder if the 1000’s of women using talcum powder products and the latest research on the link between talcum powder use and ovarian cancer has anything to do with such huge numbers. Many women have used talcum powder for years, especially in the Afro American and Hispanic community. J & J marketed their products to these women and the idea of smelling fresh and clean became a girlfriend to girlfriend positive  in smelling  “sweet and fresh like  Talcum Powder today.”
