Breaking down cancer’s defense mechanisms

A possible new method for treating pancreatic cancer which enables the body's immune system to attack and kill cancer cells has been developed by researchers. The method uses a drug which breaks down the protective barrier surrounding pancreatic cancer tumours, enabling cancer-attacking T cells to get through. The drug is used in combination with an … Continue reading Breaking down cancer’s defense mechanisms

New immunotherapy for malignant brain tumors

It is relatively easy to treat cancer in the early stages. However, it is far more difficult to successfully treat advanced cancer. Treatment of brain tumors is particularly challenging because regulatory T-cells accumulate in brain tumors and suppress an immune attack. In several steps using a new strategy and a novel drug, Burkhard Becher's team … Continue reading New immunotherapy for malignant brain tumors

Microencapsulation produces uniform drug release vehicle

Consistently uniform, easily manufactured microcapsules containing a brain cancer drug may simplify treatment and provide more tightly controlled therapy, according to Penn State researchers. "Brain tumors are one of the world's deadliest diseases," said Mohammad Reza Abidian, assistant professor of bioengineering, chemical engineering and materials science and engineering. "Typically doctors resect the tumors, do radiation … Continue reading Microencapsulation produces uniform drug release vehicle

Technique filters cancer where chemo can’t reach

A cancer therapy that removes malignant cells from a patient's cerebrospinal fluid┬ámay soon be available to prevent metastases and decrease complications of cancers involving the brain, according to Penn State medical researchers. Many cancer types metastasize to the brain -- including breast cancer, pancreatic cancer, prostate cancer and leukemia -- but by filtering these malignant … Continue reading Technique filters cancer where chemo can’t reach
