UT Southwestern Medical Center grant aids study of lung cancer in people who never smoked

Researchers at UT Southwestern Medical Center are among an elite group of cancer scientists to share a $2 million grant to find biomarkers for lung cancer that develops in people who have never smoked.

Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

Nanoparticles image breast cancer

Current methods of detecting breast cancer suffer from low sensitivity, limited spatial resolution, or the need to use complicated and expensive radioisotope-based technologies.

Targeted nanoparticles boost arsenic’s anticancer punch

Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent.

A quantum dot-based method for analysis of DNA methylation

One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes.

Discovery of new molecular pathway for targeting cancer

A UCLA study has identified a way to turn off a key signaling pathway involved in physiological processes that can also stimulate the development of cancer and other diseases. The findings may lead to new treatments and targeted drugs using this approach.

New drug compound Salirasib brings hope to pancreatic cancer patients

Every year, 42,000 Americans are diagnosed with pancreatic cancer. Few live very long, and less than 5% are still alive five years after diagnosis.

Nanoparticle Trojan horse for ovarian cancer

In a feat of trickery, Dartmouth Medical School immunologists have devised a Trojan horse to help overcome ovarian cancer, unleashing a surprise killer in the surroundings of a hard-to-treat tumor.

Estrogen can reduce stroke damage by inactivating a tumor-suppressing protein

Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say.

"Drops" of gold that burn tumors

At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light. Quidant, who was recently awarded the Fresnel Prize 2009 that recognizes the highest level of excellence amongst emerging researchers in the field of photonics, is an ICREA researcher at the UPC's Institute of Photonic Sciences (ICFO) and a fellow of the Cellex Foundation Barcelona.

Researchers investigate high-risk populations for bladder-cancer screenings

A new study by UT Southwestern Medical Center researchers sheds light on the challenges involved in identifying which high-risk population would benefit most from bladder-cancer screening.

Discovery of key protein for tumor suppression in ER+ breast cancer

Researchers from the Kimmel Cancer Center at Jefferson have identified a protein relationship that may be an ideal treatment target for ER+ breast cancer. The study was reported in the July 15 issue of Cancer Research.

Discovery of new mechanism controlling neuronal migration

The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital.

New brain visualization technology enables removal of fist-sized tumor

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman.

Study finds survival rates from GIST improving among African-Americans

New research published in the July issue of the Journal of the American College of Surgeons reveals that African Americans with gastrointestinal stromal tumors (GIST), a rare cancer that begins in the wall of the gastrointestinal tract, now have survival rates equivalent to those of Caucasians. Prior to 2000, African Americans were more likely to develop GIST and less likely to undergo surgical treatment for this type of cancer.

Childhood cancer risk rises with mother's age

Research from the Masonic Cancer Center, University of Minnesota indicates that a baby born to an older mother may have a slightly increased risk for many of the cancers that occur during childhood.
