Cell plasticity may provide clues to origin of aggressive type of breast cancer — ScienceDaily

A team of researchers, led by Candice A.M. Sauder, M.D., while a resident at the Indiana University Department of Surgery, reported online in BMC Cell Biology that healthy breast cells separated from their normal environment were able to transform into types of cells similar to those seen in metaplastic carcinoma, a form of triple negative breast cancer. The team developed 12 cell lines from the normal, healthy breast tissue from volunteer donations to the Susan G…

Unique study focuses on combined treatment approach for locally advanced pancreatic cancer

Locally advanced pancreatic cancer has the lowest survival rate of any solid tumor, with a cumulative five-year survival rate of only 4 percent for all stages of disease. Surgery is rarely an option for patients because tumors often involve vital blood vessels. Chemotherapy and radiotherapy given concurrently remain the mainstay treatment, yet to-date, no treatment has had a significant impact on improving outcomes. “To move the needle forward toward prolonged survival and better treatment outcomes, our research team created a combined investigational regimen for patients with locally advanced pancreatic cancer,” said Richard Tuli, MD, PhD, a radiation oncologist in the Department of Radiation Oncology and a member of the Samuel Oschin Comprehensive Cancer Institute. …

New myeloma-obesity research shows drugs can team with body’s defenses

And with current obesity trends in the United States and especially in South Texas, that’s ominous. “I’m predicting an increase in multiple myeloma,” said Edward Medina, M.D., Ph.D., “and with the obesity problems we see in the Hispanic population, there could be a serious health disparity on the horizon.” Dr. Medina, a hematopathologist and assistant professor in the Department of Pathology at The University of Texas Health Science Center at San Antonio, is looking at exactly how obesity causes an increased risk for myeloma…

Cetuximab or bevacizumab with combi chemo equivalent in KRAS wild-type MCRC

“The CALGB/SWOG 80405 trial was designed and formulated in 2005, and the rationale was simple: we had new drugs –bevacizumab and cetuximab– and the study was designed to determine if one was better than the other in first-line for patients with colon cancer,” said lead study author Alan P. Venook, distinguished Professor of Medical Oncology and Translational Research at the University of California, San Francisco, USA. The CALGB/SWOG 80405 trial studied patients whose tumours were KRAS wild-type at codons 12 and 13. …

People with HIV with early-stage cancers are up to four times more likely to go untreated for cancer

Life expectancy for HIV-infected people is now similar to uninfected people, but survival for HIV patients who develop cancer is not. While many studies have attempted to understand why HIV-infected cancer patients have worse outcomes, the new study, the largest of its size and scope, examined differences in cancer treatment as one potential explanation. For early-stage cancers that have the highest chance of cure with appropriate treatment, those with HIV were twice to four times as likely to not receive appropriate cancer treatment, the researchers found…

U.S. cervical cancer rates higher than previously reported, especially among older women, African-American women

Previous research finds an age-standardized rate of about 12 cases of cervical cancer per 100,000 women in the United States, with the incidence reaching a peak at age 40-44 and then leveling off. However, these estimates included women who had hysterectomies in which the lower part of the uterus, the cervix, was removed. By excluding these women, who are no longer at risk of developing this cancer, from their analysis, the researchers calculated a rate of 18.6 cases of cervical cancer per 100,000 women. They found the incidence increased steadily with age and peaked at a higher rate and at an older age, specifically in women 65-69 years old…

Negative HPV test may predict lower cervical cancer risk than a negative Pap

In a comparison of the three strategies, Julia C. Gage, Ph.D., M.P.H., of the Division of Cancer Epidemiology and Genetics, National Cancer Institute, Bethesda, MD, and colleagues analyzed data from the Kaiser Permanente Northern California (KPNC) large integrated health delivery system, which screened women age 30-64 since 2003 with both HPV and Pap testing. Data were available through 2012, and over 1 million women were screened at approximately 3-year intervals, with a mean follow-up time of 4.36 years. For each testing strategy, they estimated the cumulative risk of cervical cancer after a negative test result. …

Screening costs increased in older women without changing detection rates of early stage breast cancer — ScienceDaily

The effect of introduction of new breast cancer screening modalities, such as digital images, computer-aided detection (CAD), and use of ultrasound and MRI on screening costs among older women is unknown, although women over the age of 65 represent almost one-third of the total women screened in the US annually. …
