Enzyme controlling metastasis of breast cancer identified

“The take-home message of the study is that we have found a way to target breast cancer metastasis through a pathway regulated by an enzyme,” said lead author Xuefeng Wu, PhD, a postdoctoral researcher at UC San Diego. The enzyme, called UBC13, was found to be present in breast cancer cells at two to three times the levels of normal healthy cells. Although the enzyme’s role in regulating normal cell growth and healthy immune system function is well-documented, the study is among the first to show a link to the spread of breast cancer…

Some women still don’t underststand ‘overdiagnosis’ risk in breast screening

In a survey of around 2,200 women, Cancer Research UK scientists at University College London (UCL) found that 64 per cent felt they fully understood the information given about overdiagnosis — the chance that screening will pick up cancers that would never have gone on to cause any harm — by the National breast screening programme. Information about overdiagnosis has only been included in the NHS breast screening invitation leaflets since late 2013, meaning that overdiagnosis is likely to be a new concept for many people. But despite uncertainty over the information they were given, intentions to attend breast screening remained high, with only seven per cent of women saying they would be less likely to attend screening after receiving the overdiagnosis information. …

Increase seen in use of double mastectomy, although not associated with reduced death

Randomized trials have demonstrated similar survival for patients with early-stage breast cancer treated with breast-conserving surgery and radiation or with mastectomy. However, previous data show increasing use of mastectomy, and particularly bilateral mastectomy (removal of both breasts) among U.S. patients with breast cancer. Evidence for a survival benefit with this procedure appears limited to rare patient subgroups…

Circulating tumor cell clusters more likely to cause metastasis than single cells

“While CTCs are considered to be precursors of metastasis, the significance of CTC clusters, which are readily detected using devices developed here at MGH, has remained elusive,” says Shyamala Maheswaran, PhD, of the MGH Cancer Center, co-senior author of the Cell paper. “Our findings that the presence of CTC clusters in the blood of cancer patients is associated with poor prognosis may identify a novel and potentially targetable step in the blood-borne spread of cancer.” In their experiments the team used two versions of a microfluidic device called the CTC-Chip — both developed at the MGH Center for Engineering in Medicine — that captures CTCs from blood samples in ways that make the cells accessible for scientific testing. One version — the HBCTC-Chip — can efficiently capture extremely rare CTCs in a blood sample. …

Better classification to improve treatments for breast cancer

Cancer arises due to genetic changes which cause normal cells to develop into tumors. As we learn more about breast cancer, we are seeing that it is not one single disease — the mutations in the genes that cause different cancers are not alike, and this is why tumors respond differently to treatment and grow at different rates…

New estrogen-based compound suppresses binge-like eating behavior in female mice

“Previous data has shown that women who have irregular menstrual cycles tend to be more likely to binge eat, suggesting that hormones in women play a significant role in the development or prevention of the behavior,” said Dr. Yong Xu, assistant professor of pediatrics and senior author of the paper. “Previous data has also shown that in humans, there is a strong association between estrogen and binge eating. …
