In animal studies, CHOP researchers advance new approach to anti-tumor immunotherapy By carefully adjusting the function of crucial immune cells, scientists may have developed a completely new type of cancer immunotherapy—harnessing the body's immune system to attack tumors. To accomplish this, they had to thread a needle in immune function, shrinking tumors without triggering unwanted autoimmune responses. The new research, performed in animals, is not ready for clinical use in...

Rapid identification of changes in tumor blood vessels could help avoid ineffective therapies A new way of analyzing data acquired in MR imaging appears to be able to identify whether or not tumors are responding to anti-angiogenesis therapy, information that can help physicians determine the most appropriate treatments and discontinue ones that are ineffective. In their report receiving online publication in Nature Medicine, investigators from the Martinos Center for Biomedical Imaging at...

A new analysis has found that a type of radiation therapy called carbon ion radiotherapy can control cancer growth and prolong survival in patients with spinal tumors. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that the treatment is a promising alternative for patients whose spinal tumors cannot be surgically removed. Surgery is the mainstay of treatment for spinal sarcomas; however the tumors are one of the most...

Findings could help identify patients most likely to benefit from lung-sparing surgery A new study by thoracic surgeons and pathologists at Memorial Sloan-Kettering Cancer Center shows that a specific pattern found in the tumor pathology of some lung cancer patients is a strong predictor of recurrence. Knowing that this feature exists in a tumor's pathology could be an important factor doctors use to guide cancer treatment decisions. According to the study's authors, the findings offer...

New findings could lead to drugs that fight back when tumors don't respond to treatment Cancer drugs known as ErbB inhibitors have shown great success in treating many patients with lung, breast, colon and other types of cancer. However, ErbB drug resistance means that many other patients do not respond, and even among those who do, tumors commonly come back. A new study from MIT reveals that much of this resistance develops because a protein called AXL helps cancer cells to circumvent...

These tumors can become malignant in humans Rhode Island Hospital researchers have found that the absence of the Shp-2 enzyme near specialized cartilage cells can lead to the development of multiple benign cartilage tumors in mice, a model that recapitulates the rare human tumor syndrome metachondromatosis. Shp2 is an enzyme in the cell that regulates the activity of other proteins and signaling pathways. Mice lacking Shp2 formed two types of tumors: enchondromas and osteochondromas, and...

Brain cancer is the primary cause of cancer mortality in children. Even in cases when the cancer is cured, young patients suffer from the stress of a treatment that can be harmful to the developing brain. In a search for new target structures that would create more gentle treatments, cancer researchers are systematically analyzing all alterations in the genetic material of these tumors. This is the mission of the PedBrain consortium, which was launched in 2010. Led by Professor Stefan Pfister...

After a recent University of Illinois study showed that injection of the soy peptide lunasin dramatically reduced colon cancer metastasis in mice, the researchers were eager to see how making lunasin part of the animals' daily diet would affect the spread of the disease. "In this new study, we find that giving lunasin orally at 20 mg/kg of body weight reduced the number of metastatic tumors by 94 percent—we went from 18 tumors to only one. And that was done using lunasin...

Cancer Detection Using MRI And Sugar

redOrbit Staff & Wire Reports - Your Universe Online Researchers from University College London Centre for Advanced Biomedical Imaging (CABI) have reportedly discovered a new way to detect cancer using sugar and magnetic resonance imaging (MRI) scans. The new technique, which is known as "glucose chemical exchange saturation transfer (glucoCEST)," was developed using the knowledge that cancerous tumors consume much more glucose than healthy tissues in order to sustain their growth....
