Initial 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.
It 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.
The US Food and Drug Administration (FDA) announced the approval of vismodegib (Erivedge), for the treatment of advanced basal cell carcinoma, the most common type of skin cancer, for patients who are not eligible for surgery or radiation, and for metastatic disease.
The US Food and Drug Administration (FDA) has approved the angiogenesis blocker axitinib (Inlyta), a twice daily oral drug, as a second-line treatment for patients with advanced renal cell carcinoma.
Metastatic 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%.
Hypermethylation of TFAP2E Gene in Colorectal Cancer Associated With Unresponsiveness to the Chemotherapy Fluorouracil
A study published earlier this month in the New England Journal of Medicine, identifies specific colorectal tumors that are less responsive to chemotherapy. Researchers at the University of Magdeburg show that the hypermethylation of the transcription factor AP-2 epsilon (TFAP2E) gene results in lower expression of the TFAP2E protein and upregulation of the DKK4 gene, a gene which has been previously associated with resistance to the chemotherapy fluorouracil.
Breast 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.
In a rare case where the side effect of a cancer treatment can be explained through molecular studies, researchers have identified the reason behind the frequent skin lesion side effect among metastatic melanoma patients that take the newly approved drug vemurafenib.
A new study has made a step forward toward better characterization of sporadic ovarian tumors by identifying their DNA repair protein expression profile.
Researchers 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.
