NASA DEVELOPING COMPUTERIZED BREAST CANCER DIAGNOSTIC TOOL
A NASA-Stanford University team is in the preliminary stages
of developing a smart probe that can be used for breast cancer
detection and analysis.
The probe is designed to 'see' a lump; determine by its
features if it is cancerous; and then quickly predict how the
disease may progress. Researchers say surgeons may be able to
insert the computerized tool's needle-like tip into breast lumps
to make instant diagnoses and long-term cancer predictions.
"This device will permit us to make real-time, detailed
interpretations of breast tissue at the tip of the needle," said
Robert Mah of NASA's Ames Research Center, Moffett Field, CA. Mah
works in the Ames Neuroengineering Laboratory. "The instrument
may allow health care providers to make expert, accurate diagnoses
as well as to suggest proper, individualized treatment, even in
remote areas."
"To enable the instrument to recognize cancer and predict its
progress, we use special neural net software that is trained and
learns from experience," he said. Scientists can teach the breast
cancer diagnosis device to predict how aggressive the disease may
be.
"We hope to use this device not only to detect cancer, but to
understand the nature of an individual cancer," said Dr. Stefanie
Jeffrey, Assistant Professor of Surgery and Chief of Breast
Surgery, Stanford University School of Medicine, Stanford, CA.
"This information may help us determine the distinctive features
of a malignancy and how the disease may progress; more knowledge
about the cancer may guide us to better individualizing
treatment."
Jeffrey and Mah are working together to develop the new
device. The researchers say that, once the smart probe has been
adequately tested in the laboratory, Dr. Jeffrey will begin
testing the device on human beings, perhaps by early 1999.
"Ultrasound will help guide the doctor to properly insert the
smart probe into a breast lump," said Dr. Robyn Birdwell,
Assistant Professor of Radiology, Breast Imaging Section at
Stanford.
"The computer software uses pattern recognition to look for
tell-tale characteristics of the lump," Mah said.
"The same technology used in the portable, smart probe could
be used in other instruments to help in diagnosing and treating
cancers found in other parts of the body, including the prostate
and colon," neuroengineering team computer engineer Alex Galvagni
said.
The breast cancer tool is a spinoff from a computerized
robotic brain surgery assistant that was previously developed by
Mah and neurosurgeon Dr. Russell Andrews.
The larger brain surgery device is a simple robot that can
'learn' the physical characteristics of the brain and may soon
give surgeons finer control of surgical instruments during
delicate brain operations.
