Injectable Contraceptive is Linked to Increased Risk of Breast Cancer
April 12th 2012A large-scale study of US women between the ages of 20 and 44 shows that using the injectable contraceptive, depot medroxyprogesterone acetate (DMPA), is associated with a two-fold increase in the risk of invasive breast cancer when the contraceptive is used for at least one year.
An Indirect Way to Get at the Elusive MYC Cancer Target
April 11th 2012Scientists in Germany have potentially found a way to indirectly target the MYC oncogene-an elusive cancer therapy target to date, discovering that cancer cells with upregulated levels of MYC are dependent on AMPK-related kinase 5 to stay alive. Inhibition of ARK5 causes these MYC-dependent cells to die.
Genetic Characterization of Triple-Negative Breast Cancer
April 7th 2012Researchers at the University of British Columbia in Vancouver, Canada have sequenced and analyzed over 100 triple-negative breast tumors at the time of diagnosis, the first in-depth genomic analysis of this heterogeneous breast cancer subtype.
Best Marginal Threshold for Ductal Carcinoma in Situ Still Not Clear
March 26th 2012A wide negative margin during breast-conserving surgery should be attempted for women with ductal carcinoma in situ–this is the conclusion from an analysis published today in the Journal of the National Cancer Institute.
MBCC: What Affects Long-Term Breast Cancer Recurrence Risk?
March 19th 2012Reasons for recurrence after treatment for early breast cancer are still not well understood. Lifestyle and other longer-term factors are likely at play, but the subject is difficult to study. The best advice for cancer patients is exercise and a healthy diet.
MBCC: Treatment Targets for Triple-Negative Breast Cancer-Three Pathways to Test in the Clinic
March 16th 2012What are the latest advances in the treatment of triple-negative breast cancer? Are there new ways to molecularly characterize breast cancer tumors to identify specific mutation targets and increase the chance of response in this disease?
MBCC: No Clear Answer for Bisphosphonate Use in Early Breast Cancer
March 16th 2012Over the past several months, the results of four randomized bisphosphonate adjuvant trials in a range of different patients have been released, two of these trials showed a survival benefit for the addition of a bisphosphonate to standard systemic therapy. ER-positive patients who are postmenopausal and have had no chemotherapy seemed to benefit the most.
Prostate Cancer Study: Update to PSA Screening Data Renews Controversy
March 16th 2012Rationale for prostate cancer screening continues to be debated as an update to a large European trial reconfirms a reduction in death rates from prostate cancer in men who are screened for the disease. The study, however, found no significant difference in overall mortality between the two arms of the trial.
Estrogen May Help Lower Risk of Breast Cancer in Some Women
March 15th 2012Women who received estrogen while part of the Women's Health Initiative (WHI) trial had lower rates of invasive breast cancer compared to those who received placebo, and they were less likely to die of the disease compared to women who never took the hormone replacement therapy.
Breast Cancer Genotype, CYP2D6, Not Predictive of Tamoxifen Benefit
March 7th 2012Two studies published today help clarify how to interpret CYP2D6 genetic testing and the results will likely affect the current trend of CYP2D6 genotyping prior to tamoxifen usage in early-stage ER-positive breast cancer patients.
Dual Inhibition of VEGF and c-MET in Cancer Promises to Decrease Metastasis
March 1st 2012A combined dual inhibition of vascular endothelial growth factor (VEGF) and c-MET is showing promise in preventing tumor invasion and metastasis. The data thus far are in a laboratory model of pancreatic neuroendocrine cancer.
Oral Therapies and Food: To Eat or Not to Eat?
February 25th 2012The treatment of cancer is shifting to increasingly more oral pills. Most oncology drug labels recommend taking the pills while fasting though often there is evidence that food increases bioavailability of the medication as much as four-fold.
Semuloparin Helps Prevent Thromboembolic Events in Patients Receiving Chemotherapy
February 22nd 2012Semuloparin, an ultra-low molecular weight heparin reduces the probability that a cancer patient undergoing chemotherapy has a thromboembolic event by 64%. The results from the phase III trial also show that the benefit is not accompanied by an increase in major bleeding, a potential side effect of semuloparin.
Omega-3 Consumption Linked to Lower Incidence of Colon Polyps in Women
February 17th 2012Researchers at Vanderbilt University Medical Center have found that eating omega-3 fatty acids regularly can result in prevention of colon polyp formation. The 33% reduced risk of colorectal adenomas was seen in women, but not in men.
Novel Drug, MDV3100, Will Likely Have a Major Role in Prostate Cancer Treatment
February 15th 2012The new drug, MDV3100, extended overall survival by 4.8 months (P < .001) and reduced the risk for death by 37% as compared to placebo in men with castration-resistant prostate cancer who had progressed after treatment with docetaxel.
Mother-To-Be and Cancer Patient-New Treatment Guidelines
February 14th 2012Four publications on cancer treatment during pregnancy were published last week in the journal Lancet, serving as new treatment guidelines for chemotherapy and surgery in pregnant patients with solid tumors and hematologic malignancies.
Urine-Based Markers May Pinpoint Prostate Cancer Patients With Aggressive Disease
February 6th 2012Initial results of a multicenter trial show that 2 biomarkers, PCA3 and T2-ERG, are found at high levels in prostate cancer compared to noncancerous prostate cells and correlate well with 2 indicators of aggressive prostate cancer, tumor volume and Gleason score.
New Way to Predict Prostate Cancer Severity-Size of Prostate
February 1st 2012It is still difficult to gauge the probability that a low-risk prostate cancer patient may be upgraded to a higher prostate cancer stage. Researchers at Vanderbilt University Medical Center have now determined that smaller prostates were more likely to evolve into more serious, aggressive disease.
Why BRAF-Mutated Colorectal Cancers Don't Respond to BRAF Inhibitors
January 30th 2012Metastatic melanomas that harbor the V600E mutation in the BRAF gene respond rapidly to vemurafenib (Zelboraf), the BRAF V600E inhibitor. But While vemurafenib results in a response in about 80% of melanoma patients, the clinical response among CRC patients is not greater than 5%.
Younger Breast Cancer Patients Have More Adverse Quality of Life Issues
January 23rd 2012Breast cancer survivorship continues to rise, but the long-lasting psychosocial and quality-of-life changes that occur after treatment need to be studied, as treatment outcomes can lead to negative side effects that outlast the treatment.
Processed and Red Meat Consumption Linked to Slight Increase in Risk of Pancreatic Cancer
January 19th 2012Researchers in Sweden who analyzed several prospective studies found an increased risk of pancreatic cancer associated with processed meat consumption. They also found that eating red meat is linked to pancreatic cancer among men.
