View Related  Mayo Clinic study reveals longer survival times following staging procedure Pancreatic cancer, even when diagnosed early, often has a poor prognosis. Signs and symptoms may not appear until the cancer is quite advanced and surgical removal is not possible. Pancreatic cancer, as a result, is a leading cause of death. View Related  Mayo Clinic Researchers Find Common Gene Disorder Doubles Risk of Lung Cancer, Even Among Nonsmokers Mayo Clinic researchers have found that carrying a common genetic disorder doubles the risk of developing lung cancer in smokers and nonsmokers. View Abstract  A probe so sensitive that it can tell whether or not a cell living within the human body is veering towards cancer development may revolutionize how future colonoscopies are done, say researchers from the Mayo Clinic in Jacksonville, Fla. View Related  This release is being sent in a social media format, in conjunction with the National Cancer Institute, part of the NIH. A new study being presented at the American Society of Clinical Oncology meeting in Chicago (Abstract #4020), may change treatment practice in about 25 percent of patients with colon cancer and is the basis for proposed changes to the way colorectal cancers will be staged. View Related  Study to be presented at the American Society of Clinical Oncology annual meeting The number of women undergoing mastectomy (total breast removal) for early-stage breast cancer has increased in the last three years at Mayo Clinic in Rochester. The increase follows a steady decline during the prior seven years. View Related  Study to be presented at the American Society of Clinical Oncology annual meeting Adding a second monoclonal antibody drug to chemotherapy looks promising for treatment of diffuse large B-cell lymphoma, according to Mayo Clinic researchers working with the North Central Cancer Treatment Group (NCCTG) (http://ncctg.mayo.edu/). View Related  Findings will enable patients with advanced colon cancer to complete treatment with fewer side effects; study to be presented at the American Society of Clinical Oncology Researchers in the North Central Cancer Treatment Group (NCCTG) have shown that patients who receive intravenous calcium and magnesium before and after the chemotherapy drug oxaliplatin for the treatment of advanced colon cancer experience a significantly reduced incidence and severity of neurological side effects (neurotoxicity). View Related  Study to be presented at the American Society of Clinical Oncology annual meeting Mayo Clinic researchers and collaborators say they have conclusively demonstrated that a substantial subset of colon cancer patients should not receive chemotherapy because it provides no clinical benefit, and actually may reduce survival time.

View Related  Increased expression of SULF2 enhances cancer cell growth and migration, whereas decreased expression reduces both. Deadly and difficult to treat, liver cancer has long resisted attempts by researchers to develop ways to prolong life and prevent recurrence. But Mayo Clinic Cancer Center, in collaboration with the National Cancer Institute, reports in the April issue of Hepatology that the protein sulfatase 2 (SULF2) may provide one of the keys needed to begin the design of new therapies. View Abstract    Mouse study shows dopamine blocks tumor-feeding blood vessels "Sometimes new drugs may not be the answer. We looked instead at a novel use for an established product and have found very promising results," says Mayo Clinic oncology researcher Sujit Basu, M.D., Ph.D.  CT colonography, also known as virtual colonoscopy, underwent rigorous studies at Mayo Clinic for more than 10 years, while the stool DNA test was conceived and developed by Mayo Clinic researchers. View Related  The research team discovered that women whose atypia tissue expressed COX-2 enzymes were more likely to develop breast cancer subsequently, and that the more the enzyme expressed, the higher the risk. View Abstract  News in Minnesota Yuichi Machida, Ph.D., of the University of Virginia, will join Mayo Clinic's Division of Oncology Research in May.  ALTTO (Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization study) "There have been major improvements in the management of patients with early breast cancer in the last few years, so this new study builds on this knowledge and sets an example of the new era: good science, good worldwide collaboration," said Edith Perez, M.D., an oncologist in the North Central Cancer Treatment Group (NCCTG) at Mayo Clinic in Jacksonville, Fla., who will lead the study for TBCI. View Related Agreement strengthens relationship and spawns new scientific collaborations "TGen takes seriously our commitment to work toward helping patients with cancer and other disorders.

View Related  Study lays foundation for future development of effective treatments "This model helps us understand the genetic properties that lead to multiple myeloma and provides a framework for developing better therapies," said Leif Bergsagel, M.D., a Mayo Clinic physician and lead investigator for the study. "We will now be able to test new treatments on models." View Abstract Mayo Clinic Cancer Center IDs two signatures predicting survival The team found two survival-related 50-gene signatures, one for each of the two cancer types. These were nonoverlapping and largely unique in gene content compared to previously identified predictive gene expression signatures for lung cancer developed by other researchers. View Related   Named professorships at Mayo Clinic represent the highest academic distinction for a faculty member. Sandra Gendler, Ph.D., was named the David F. and Margaret T. Grohne Research Professor in Therapeutics for Cancer Research. Richard Vile, Ph.D., a consultant in the Department of Molecular Medicine and Department of Immunology at Mayo Clinic Rochester, was honored with The Richard M. Schulze Family Foundation Professorship.  Research into the B7 molecules has been a "family affair" at Mayo. Many Mayo immunologists have joined together to tackle various aspects of their function and behavior and have discovered how they function. View Related    Using two different endoscopes together is better than using one to stage lung cancer, and is also much more precise and less invasive than the surgical method now most commonly used. "Both scopes together found more malignant lymph nodes than did the use of a single endoscope," says the study's lead investigator, Michael Wallace, M.D., M.P.H., Professor of Medicine at Mayo Clinic, Jacksonville, Fla. "Doing both procedures at once takes little time, requires only a mild sedative, and patients go home the same day." View Abstract Sound waves may help early detection of heart failure caused by Trastuzumab "Breast cancer is the second most common form of cancer in women, and the leading cause of death," says Bijoy K. Khandheria, M.D., chair, Mayo Clinic Cardiovascular Services, researcher and co-investigator of the study. "Anticancer drugs like Trastuzumab have substantial benefits, but in some patients the anticancer drug cross-reacts with the heart muscle. Therefore, methods to detect and halt heart muscle damage is therefore urgently required." View Abstract    Discovery's Edge "When we examined human breast tissue we were blown away by how dramatic and obvious the centrosome abnormalities were in the tumors," says Jeffrey Salisbury, Ph.D. "And that was literally on day one." View Related  News from Rochester, Minn. Stereotactic radiosurgery uses precisely focused radiation to treat tumors and other abnormal growths in the brain. View Related  Study's authors recruit patients for a clinical trail, another step in this ongoing research "We are now quite convinced that in most patients with pancreatic cancer the diabetes is caused by the cancer and not the other way around," says Suresh Chari, M.D., a Mayo Clinic gastroenterologist and the study's lead author. "Our next step is to identify a biomarker for pancreatic cancer-induced diabetes in order to screen patients with new-onset diabetes for early pancreatic cancer and provide surgical treatment as quickly as possible."

Read Script  Removing the entire kidney from younger patients with small kidney tumors may lead to decreased overall survival. "For patients with small kidney tumors, removal of the entire kidney may be associated with long-term consequences that we did not previously recognize when compared to removal of just the tumor," says the study's lead author, R. Houston Thompson, M.D., a Mayo Clinic urologist currently serving a fellowship at Memorial Sloan-Kettering Cancer Center. View Related Collaboration aims to find high-tech solutions for quicker diagnosis, better treatments "This facility will allow us to explore projects in medical imaging and radiology that can provide faster and better information for our physicians, and in turn, improved treatments for our patients," said Bradley Erickson, M.D., Ph.D., head of Mayo's Radiology Informatics Lab. View Related   Mayo Clinic Rochester "For many people, the beginning of a new year represents a good time to take steps toward quitting smoking," says Christi Patten, Ph.D., the Mayo Clinic clinical psychologist leading this study. "Research has shown that positive support and encouragement from someone who cares about a smoker can be effective in helping that person to quit. This study is designed to identify the best ways to teach support people how to help." View Related Procedure also could prevent recurrence "We show that if you kill tumor cells directly in the tumor itself, you can get a weak immunity against the tumor, but if you use this virus to kill tumor cells in the lymph nodes, you get a higher immunity against the tumor," says Richard Vile, Ph.D., a Mayo Clinic specialist in molecular medicine and immunology and the study's principal investigator. View Abstract  Presented at the 2007 San Antonio Breast Cancer Symposium "We need to be aware that this kind of cancer is high risk and we should do all that we can to prevent brain metastasis," says Stephanie Hines, M.D. "For women with triple negative breast cancer, improvements in outcome will likely come when new treatments for this type of cancer are successfully developed." View Related  Presented at the 2007 San Antonio Breast Cancer Symposium "It appears that biology and not only size matters when it comes to selecting therapy for small, invasive tumors," says the study's lead researcher, Surabhi Amar, M.D., a fellow in Hematology/Oncology at Mayo Clinic in Jacksonville. View Related   News from Jacksonville, Fla. "Maintaining our FACT accreditation continues to be an important achievement for the transplant program," says program director, pediatric hematologist/oncologist Michael Joyce, M.D., Ph.D., with Nemours Children's Clinic. "The physicians, hematology/oncology nursing, allied health and laboratory staff at Mayo, Nemours and Wolfson all worked extremely hard to achieve this goal." View Related  New treatment provides a 'more frequent, rapid and deep response' "For newly-diagnosed multiple myeloma patients, this new drug treatment provides a more frequent, rapid and deep response, compared with earlier treatment options," said Craig B. Reeder, M.D., a Mayo Clinic hematologist/oncologist and lead investigator of the study. View Related Presented - American Society of Hematology's 2007 meeting "We believe this to be the first large systematic evaluation of the risk factors leading to leukemic transformation in primary myelofibrosis," says Jocelyn Huang, M.D., lead author and hematology researcher at Mayo Clinic.

"Platinum-resistant ovarian cancer responds poorly to traditional therapies, and we've been working toward developing more effective treatments for this disease. This combination looks very promising." View Abstract  New vaccine for glioblastoma multiforme, an aggressive brain cancer, is now being offered through a clinical trial at Mayo Clinic in Jacksonville. The vaccine represents a fresh and fairly simple approach to treating this cancer, says neurosurgeon Kent New, M.D., Ph.D., who will be leading the study at Mayo. About 40 percent of these tumors display a particular protein on their surface and the vaccine is designed to trick the patient's immune system into thinking the protein is "foreign" in order to mount a killing response. View Related  According to the National Cancer Institute, more than 20,000 people in the U.S. will be diagnosed with a brain tumor in 2007 and almost 13,000 will die from the cancer. "We are pleased to have a new and promising therapy to offer patients who want to participate in this clinical trial," says Kent New, M.D., Ph.D., neurosurgeon at Mayo Clinic in Jacksonville, Fla. "The results, so far, have exceeded expectations." View Related  Up to 30 percent of patients with colon and rectal cancer may develop a bowel obstruction View Related           "We hope to find more effective nonhormonal options to assist women, and flaxseed looks promising," says Sandhya Pruthi, M.D., Mayo Clinic breast health specialist and the study's primary investigator. Dr. Pruthi's team chose to research flaxseed because it is a phytoestrogen (plant-based estrogen source). Flaxseed contains lignans and omega-3 fatty acids. Lignans are antioxidants with weak estrogen-emulating characteristics, and have some anti-cancer effects. Flaxseed also appears to have anti-estrogen properties and has been shown in some recent research trials to decrease breast cancer risk.

View Related     Women with at least three sites of cellular atypia in breast tissue are nearly eight times more likely than average women to develop breast cancer, according to findings of a Mayo Clinic Cancer Center led study of women with atypical hyperplasia. "With the ability to stratify the risk of breast cancer in women with atypia, we can have more informed discussions with our patients regarding their personal risk," says Amy Degnim, M.D., a Mayo Clinic surgeon and study author. "This will help us to have individualized discussions regarding how aggressively to pursue risk-reduction treatments." View Abstract  Jacksonville, Fla. This technology, an intraoperative Magnetic Resonance Imaging (MRI) system known as the IMRIS Neuro system, allows surgeons to use real-time imaging as they operate and uses a unique ceiling-mounted track that moves the MRI system to the patient rather than the patient having to be moved to the magnet. View Related   Radiology researchers at Mayo Clinic have invented a diagnostic imaging tool with remarkable capabilities. It's called Magnetic Resonance Elastography or MRE. MRE can measure elasticity - detecting abnormal hardening of liver tissue - sparing some patients the need for a biopsy and allowing physicians to begin intervention aimed at treating their disease before it progresses to cause irreversible damage.
