New Michigan tech better detects cancer in women with denser breast tissue

Women with dense breast tissue have an increased risk of cancer. This is because digital girlfriend mammograms are more likely to miss suspicious masses.

To better address this concern, Detroit’s Barbara Ann Karmanos Cancer Institute is the first company to purchase a new system developed in Michigan that has been approved by the U.S. Food and Drug Administration. Circumstances that make cancer difficult to detect.

This is a 3D whole breast ultrasound tomography system called SoftVue. For imaging, the woman lay prone on a perforated horizontal platform. Their breasts are placed in a warm water bath her one at a time. They are imaged using ultrasound and sound itself.

The device automatically collects 3D tomographic images by moving a “ring of transducers” vertically from the tip of the breast to read the FDA description.

“This could be a life-saving tool,” said Natasha Robinette, Ph.D., radiologist and chief of clinical services for imaging at the cancer center.

“Whether it is digital mammography or SoftVue, all screening tools are for early detection of cancer and to increase a woman’s chances of being cancer-free after treatment.”

Used in combination with mammography, the system detects 20% more cancers than mammography alone and is 8% more specific, meaning fewer false positives, says Robinette. .

“It can detect that something is there a little better, but don’t worry,” says Robinette.

This means fewer patients needlessly return to medical centers, endure fear, and worry that something is wrong.

As it is today, women with dense breasts may have to undergo a mammogram, plus a breast magnetic resonance imaging (MRI), which is costly and takes about an hour, or an ultrasound of the whole breast. Ultrasound can be done automatically by mechanical compression or manually with a wand as it is done on the pregnant woman’s abdomen.

Anytime the process is manual, there’s always the chance that something will be missed, says Robinette.

However, women do not always get additional imaging tests. Patients are usually required to receive a phone call or letter and schedule a subsequent appointment for further testing as directed by their doctor.

Robinette said the FDA has approved that SoftVue can be done at the same time as a mammogram if the breast is considered or known to be dense. The examination takes about 3 to 5 minutes per breast, about 10 minutes total, and “may be conscious of body image concerns or exposing yourself for medical procedures.” A more private screening option for people. In video demonstrations, the patient is always covered with a machine or gown.

“SoftVue images are intended to be interpreted in conjunction with mammogram results to enhance screening,” read the FDA-issued abstract and found no known contraindications or safety concerns. .

According to Robinette, the process has been streamlined and the resulting images, including color, are easier for radiologists to read.

The FDA has determined that the SoftVue system’s potential risks are in terms of diagnostic accuracy, false positives, and false negatives, but the FDA has determined that the benefits outweigh the risks.

For ten years this system has been in development. Karmanos, part of Grand-Blanc-based McLaren Health Care, launched Delphinus Medical Technologies in Novi and jointly developed the device.

Delphinus President and CEO Mark J. Forchette said: statement.

Persistent supply chain issues related to the pandemic could limit broader distribution, at least in the short term, but Robinet expects implementations elsewhere.East Michigan and The medical system in the South is considering SoftVue.

Karmanos has 16 sites, but the SoftVue system will be installed, at least initially, only at the cancer center’s main campus in Detroit. Robinette said the unit will be up and running by the end of the year and will be operated by an ultrasound technician. She hopes to eventually be offered at the Farmington Hills Breast Care Center in Karmanos as well.

The aim of the study was to help patients with dense breast tissue, found in about 40% of women who are four times more likely to develop breast cancer.

On a mammogram, the more granular the breast tissue, the whiter the breast will appear. Suspicious blobs also appear white, so you can hide them from view.

Cancer starts from granular tissue, not adipose tissue, so the more granular tissue you have, the higher your risk of cancer, Robinette said.

At this time, experts disagree about what other tests should be done, reports the American Cancer Society.

Letters sent to women with dense breasts are not standardized. “And I think there’s always been confusion on the patient’s part. What does it mean that your breasts are dense? I think they’re confused about how to move forward.” Robinette said.

Some women may miss. For example, breast MRI is reserved for people with other risk factors, such as close relatives with breast cancer or those previously diagnosed with ovarian or breast cancer.

Patients may not follow up, or doctors may decide that no further imaging tests are necessary.

“Such women either choose to do something extra or come back another year for a mammogram because they have not done so, leaving them somewhat precarious. increase.”
