Although studies have shown that women with a false-positive result from mammography screening have an increased risk of developing breast cancer later in life compared with women who only have negative results, a new Danish study examined how much of the excess risk was due to misclassification...
Despite advances in the treatment of diffuse large B-cell lymphoma (the most common subtype of non-Hodgkin lymphoma), including the introduction of rituximab (Rituxan), diffuse large B-cell lymphoma patients living in low-socioeconomic-status neighborhoods have a 34% greater risk of dying from...

The findings suggest that regular physical activity, even of...
An analysis of the gut microbiome in patients from three clinical groups representing the multistage progression in colorectal cancer has found that the composition of the gut microbiome differentiates individuals with healthy colons from those with adenomas and carcinomas. Adding gut microbiome...
Despite the fact that smoking increases the probability of cancer recurrence and reduces survival time, many cancer survivors continue to smoke. In a new study, nearly 1 in 10 cancer survivors reported being current smokers 9 years after their diagnosis, and 83% were daily smokers averaging about...
A phase Ib study has found that a combination of the EGFR-targeted agents afatinib (Gilotrif) and cetuximab (Erbitux) yielded clinical responses in patients with EGFR-mutant lung cancer that had stopped responding to the EGFR inhibitors erlotinib (Tarceva) and gefitinib (Iressa). The combination...

The results from the European Society for Medical Oncology (ESMO)-led Global Opioid Policy Initiative (GOPI) project show that due to a lack of access to essential opioids, more than 4 billion people—over half the world’s population—live in countries where regulatory barriers,...
Approximately 50% of metastatic melanomas harbor the BRAF mutation, and although most of these melanomas respond dramatically to treatment with BRAF inhibitors, such as vemurafenib (Zelboraf) and dabrafenib (Tafinlar), nearly all develop resistance to the drugs within 7 to 8 months. While previous...
Most patients with estrogen receptor–positive metastatic breast cancer who initially respond to endocrine treatments will eventually develop resistance to the therapies. A study by Ido Wolf, MD, Head of the Oncology Department at the Tel Aviv Sourasky Medical Center in Israel, and colleagues...
