Supreme Court Ruling Invalidates Myriad’s BRCA Gene Patents
June 14th 2013The Supreme Court announced a unanimous 9-0 decision that genes cannot be patented. After a long legal battle, the high court ruled against Myriad’s patents on two breast cancer susceptibility genes-BRCA1 and BRCA2-declaring that genes are products of nature and cannot be treated as inventions.
ASCO: Frequent Genetic Mutations in Black Women With Breast Cancer
June 7th 2013A single-center study analyzed the frequency of breast cancer susceptibility mutations among black women diagnosed with breast cancer. The findings suggest that broader genetic screening may be beneficial for these women. The study also suggests that family history is not the only criteria by which patients at risk for breast cancer can be identified.
ASCO: Triple-Negative Breast Cancer Response to Neoadjuvant Chemotherapy by Subtype
June 7th 2013In a study presented at ASCO, a team of researchers used microarrays to characterize 130 triple-negative breast cancer patients treated with neoadjuvant chemotherapy to see whether certain subtypes are more likely to respond to the treatment.
ASCO: Long-Term Tamoxifen Benefit for Breast Cancer Confirmed
June 3rd 2013Women diagnosed with estrogen-receptor (ER)-positive breast cancer who took tamoxifen for 10 years as adjuvant therapy had lower risk of late recurrence and lower risk of death compared to those who took the drug for 5 years. These results corroborate the findings of the international ATLAS trial.
Conservative vs Aggressive Treatment in Older Prostate Cancer Patients
May 28th 2013Survival data of prostate cancer patients 70 and older show that those with three or more comorbidities and low- or intermediate-risk prostate cancer are less likely to die from prostate cancer than another health issue. But those with aggressive, high-risk disease are more likely to die from their prostate cancer.
FDA Approves Erlotinib (Tarceva) as First-Line Lung Cancer Therapy for Certain Patients
May 17th 2013The FDA approved a label expansion for erlotinib (Tarceva), along with the cobas EGFR mutation diagnostic test, to include patients untreated metastatic NSCLC patients whose tumors have either a deletion in exon 19 or exon 21 (L858R) substitution mutations in the EGFR gene.
Genomics Studies Identify Testicular Cancer Risk Variants
May 17th 2013Two genome-wide studies have identified a total of 12 new genetic loci associated with a higher risk of testicular cancer. The risk-associated genetic variations could help clinicians single out higher-risk men for screening and early detection.
US Cancer Organizations Say Medicare Cuts Will Negatively Impact Cancer Patients
April 29th 2013Four of the nation’s cancer organizations--including the COA and ASCO--believe that the sequestration cuts will impact the treatment of cancer patients on Medicare and have sent letters to Congress and the Department of Health and Human Services.
AACR: Immunotherapy Antibody Has Activity in Range of Solid Tumors
April 10th 2013The anti-PD-L1 antibody MPDL3280A is effective for several different cancers and was well tolerated. Responses were seen in lung, kidney, colon, and stomach cancer patients. All patients who responded are continuing to respond to the treatment.
AACR: Anti-PI3K/MEK Inhibitor Targeted Therapy Combo Shows Activity
April 9th 2013A new agent, SAR245409, that simultaneous targets two pathways important for the growth of tumors--the PI3K/mTOR pathway and the MAPK pathway--has shown activity in advanced solid tumors, according to results from a phase I trial presented at the American Association for Cancer Research Annual Meeting.
AACR: Triple-Negative Breast Cancer-Utilizing Biomarkers for Better Therapeutic Strategies
April 8th 2013Washington, DC-“Triple-negative breast tumors are composed of mosaic cancer cells with distinct genetic aberrations,” said Jorge S. Reis-Filho, MD, PhD, a surgical pathologist at the Memorial Sloan-Kettering Cancer Center in New York, who combines traditional pathology, gene expression profiling, and genomics techniques to understand rare breast tumor types, including triple-negative diseases.
AACR: T-DM1 Most Effective in Breast Cancer Patients With High HER2 Expression
April 8th 2013Researchers participating in the phase III EMILIA trial have identified tumor biomarkers that can identify patients that are more likely to benefit from T-DM1. In the trial, women whose tumors had higher HER2 expression were most likely to benefit from the therapy.
Novel Antibody Directed at Chronic Lymphocytic Leukemia
April 4th 2013Researchers have identified a novel monoclonal antibody directly targeted against a receptor found in abundance on chronic lymphocytic leukemia (CLL) cells, but not normal B cells. The humanized antibody can directly kill CLL cells.
Potential Target for Castration-Resistant Prostate Cancer Discovered
April 4th 2013Researchers have identified a mechanism by which prostate cancer resists hormonal therapy to develop into castration-resistant prostate cancer (CRPC). The protein SIAH2 keeps a fraction of androgen receptors constitutively active in prostate cancer cells.
Imaging in Prostate Cancer-Current Standards and Technology in Development
March 25th 2013Imaging is important for both the diagnosis and management of prostate cancer. Standard techniques used in everyday clinical practice depend on the stage of the disease. Several new experimental modalities are currently in development to better identify and diagnose patients with progressive disease.
