Thyroid cancer genome analysis finds markers of aggressive tumors

The finding suggests the potential to reclassify the disease based on genetic markers and moves thyroid cancer into a position to benefit more from precision medicine. “This understanding of the genomic landscape of thyroid cancer will refine how it’s classified and improve molecular diagnosis. This will help us separate those patients who need aggressive treatment from those whose tumor is never likely to grow or spread,” says Thomas J. …

Promising results shown with targeted approaches in subsets of non-small cell lung cancer

“Reports of lung cancers bearing mutations in BRAF have generated considerable interest because these mutations may be associated with increased sensitivity to BRAF tyrosine-kinase inhibiting agents,” says lead author Dr David Planchard, pulmonary oncologist at the Gustav-Roussy Cancer Campus, Paris, France. Planchard says studies suggest that activating BRAF mutations are present in around 2% of lung carcinomas — approximately 80% of which are V600E mutations. The BRAF V600E mutations are frequently associated with shorter disease-free, overall survival, and lower response rates to platinum-based chemotherapy. …

Multiple myeloma study uncovers genetic diversity within tumors

"What this new work shows us is that when we treat an individual patient with multiple myeloma, it’s possible that we’re not just looking at one disease, but at many — in the same person, there could be cancer cells with different genetic make-ups," said co-senior author Todd Golub, the Broad Institute’s Chief Scientific Officer and Charles A. Dana Investigator in Human Cancer Genetics at the Dana-Farber Cancer Institute. Golub is also a professor at Harvard Medical School and an investigator at Howard Hughes Medical Institute. …

Gene mutation may have effect on benefit of aspirin use for colorectal cancer

Colorectal cancer is a leading cause of cancer-related death worldwide. Randomized controlled trials have demonstrated that aspirin use reduces the risk of colorectal cancer, according to background information in the article. Experimental evidence has suggested that BRAF-mutant colonic cells might be less sensitive to the antitumor effects of aspirin than BRAF-wild-type (the typical form of a gene as it occurs in nature) neoplastic cells. …
