Racial differences in severity of breast cancer presentation confirmed

African-American women are diagnosed with more advanced breast cancer than Caucasians, according to a new, single hospital study.

NanoSIMS instrument clarifies nutrient cycle

Scientists at the University of Southern California have applied a nanoscale imaging method to a biological system, helping to clear up an old puzzle of the global carbon and nitrogen cycle.

Abiraterone reduces levels of prostate specific antigen

For prostate cancer patients whose tumors have continued to grow despite medical or surgical castration, a new drug candidate that inhibits production of male hormones anywhere in the body is showing promise in early trials.

Orlistat weight loss drug points to new cancer treatments

Based on their surprising discovery that an obesity drug can kill cancer cells, scientists at Wake Forest University School of Medicine have made a new finding about the drug's effects and are working to design more potent cancer treatments.

Modified herpes simplex virus shows promise in early clinical trial

A virus that has been specifically designed by scientists to be safe to normal tissue but deadly to cancer is showing early promise in a preliminary study, researchers said at the ESMO Conference Lugano (ECLU), Switzerland.

New minimally invasive method of treating cancer

A team of biomedical engineers at Virginia Tech and the University of California at Berkeley has developed a new minimally invasive method of treating cancer, and they anticipate clinical trials on individuals with prostate cancer will begin soon.

New working principle in cancer treatment

Due to defects in chromosomal distribution, a majority of tumor cells would not be able to survive were it not for a trick that cancer cells have developed to avoid this chaos in the genetic material.

Hearing loss and von Hippel-Lindau disease

Patients with the genetic disorder von Hippel-Lindau disease may suddenly experience hearing loss because of a tumor-associated hemorrhage in the inner ear, according to a study in the July 4 issue of JAMA.

Are we looking at cancer vaccine trials the wrong way?

Ongoing therapeutic cancer vaccine trials have yet to show evidence of vaccines spurring a patient's immune system to shrink tumors -- yet patients who receive these vaccines in trials tend to live longer and respond better to subsequent treatment.

Biomira files NDA for novel inhibitor of hypoxia-inducible factor-1 alpha

Biomira Inc. has announced that it has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration for PX-478. PX-478 has been shown in preclinical studies to inhibit hypoxia-inducible factor (HIF)-1 alpha, a protein that controls the transcription of a number of genes whose products are important for tumor growth and survival.

Genetic mutation that may alter response to cancer therapeutics found

Researchers from Eli Lilly & Company and the Phoenix-based Translational Genomics Research Institute (TGen) today announced finding a novel recurring mutation of the gene AKT1 in breast, colorectal and ovarian cancers.

Fat kills cancer!

Researchers in Slovakia have been able to derive mesenchymal stem cells from human adipose, or fat, tissue and engineer them into "suicide genes" that seek out and destroy tumors like tiny homing missiles.

Discovery of method to identify how cancer evades the immune system

One of the fundamental traits of a tumor - how it avoids the immune system - might become its greatest vulnerability, according to researchers from the University of Southern California. Their findings, demonstrated in human breast and colorectal cancers, indicate that a technique for determining a tumor's "immune signature," could be useful for diagnosing and treating specific cancers.

Induction chemotherapy adds to survival rates in lung cancer patients

Patients with inoperable non-small cell lung cancer who receive an initial high dose of chemotherapy before their treatment begins can expect an increase in overall survival, according to a study in the July 1 issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of ASTRO.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

Breast cancer survival runs in the family

The chances of developing breast cancer are to some extent inherited, but important new findings suggest survival also runs in the family.

Multiple-electrode radiofrequency ablation safe and effective way of treating patients with liver cancer

Multiple-electrode radiofrequency ablation is a safe and effective way of treating patients with liver cancer that can be completed in less time than current ablation techniques, according to a recent study conducted by researchers at the University of Wisconsin in Madison.

Scientists discover role of ataxia telangiectasia mutated protein in DNA repair

Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), National Cancer Institute (NCI), and Integrative Bioinformatics Inc. have made an important discovery about the role of an enzyme called ataxia telangiectasia mutated protein (ATM) in the body's ability to repair damaged DNA.
