The second phase of Karisma is about to start

One of the focuses of Karma is to reduce the number of women diagnosed with breast cancer. There are several ways of decreasing the risk of breast cancer. Interventions range from increased physical activity to prophylactic mastectomy (surgically removing the breasts). The Karma Intervention Trial, Karisma, aims at identifying the optimal preventive dose of the…

Identifying women at increased risk of interval cancers

Using data from the Karma Cohort, Mikael Eriksson, Karolinska Institutet, has developed a risk prediction tool that identifies women at very high of developing an interval cancer. Interval cancers are breast cancers diagnosed in the interval between two scheduled mammography screens. Interval cancers are considered to particularly aggressive cancers but are quite heterogeneous in their…

First thesis based on the Karma Study published

On the 15th of January, Dr Thang Thrinh, Karolinska Institutet, defended his thesis entitled ”Determinants of breast cancer risk; focusing on mammographic density”. Thang’s thesis deals with how physical activity, alcohol consumption and cigarette smoking affect the risk of breast cancer through their influence on mammographic density. Mammographic density is defined as the radiographically dense…

Karma launch Karisma, a randomized clinical trial, to identify an optimal Tamoxifen dose for reducing risk of breast cancer.

Tamoxifen has been used for several years as adjuvant therapy for women diagnosed with breast cancer. Tamoxifen was introduced already in the 1970s and reduces the risk of breast cancer recurrence with approximately 30%. Recent studies also indicate that use of Tamoxifen as primary prevention for healthy women at high risk reduce breast cancer incidence….

Karma researchers use exome sequencing of plasma DNA for non-invasive monitoring of tumor burden

Non-invasive monitoring of tumor burden hold great promise for early detection of recurrent breast cancer. Karma researchers recently evaluated and improved exome sequencing to interrogate trace amounts of breast tumors in the plasma of breast cancer patients. “We are encourage by the results”, says Daniel Klevebring, lead author of the study. The researchers are now…

Karma validates volumetric breast density measurement tool

KARMA is the first study validating the performance of a volumetric breast density software (VolparaDensity) in a large-scale setting. Results of the study show that distributions of volumetric density are similar across different vendor platforms and that Volpara breast density is associated with established density determinants and breast cancer risk. Link to published article: Cancer…

Karma plans a randomized clinical trial to investigate the effect of different doses of Tamoxifen through measuring the decrease of breast density in healthy women.

Tamoxifen has been used for several years as adjuvant therapy for women diagnosed with breast cancer. Tamoxifen was introduced already in the 1970s and reduces the risk of breast cancer recurrence with approximately 30%. Recent studies also indicate that use of Tamoxifen as primary prevention for healthy women at high risk reduce breast cancer incidence….

Karma launch clinical trial for breast cancer detection with new techniques.

Karma Kamera is the study name of a clinical trial at Södersjukhuset, Stockholm, introducing a new technique developed by Real Imaging (realimaging.com). Real Imaging’s 3D Functional Metabolic Imaging and Risk Assessment (MIRA) technology is intended to provide a non-invasive non-radiation, and examinee-friendly procedure to determine breast health through the acquisition and analysis of 3D metabolic…

Breast cancer researcher connected to Karma wins L’Oreal women’s science fellowship

Dr Li Jingmei, 31, received this year’s UNESCO-L’Oreal International For Women In Science Fellowship, one of 15 women scientists around the world to do so. Li Jingmei currently work as postdoctoral research fellow at the Agency for Science, Technology and Research’s Genome Institute of Singapore, but have strong connections to Karolinska Institutet and the Karma-group She…

Study shows mammographic density reduction as a prognostic marker of improved survival

Mammographic Density Reduction Is a Prognostic Marker of Response to Adjuvant Tamoxifen Therapy in Postmenopausal Patients With Breast Cancer Tamoxifen treatment is associated with a reduction in mammographic density and an improved survival. However, the extent to which change in mammographic density during adjuvant tamoxifen therapy can be used to measure response to treatment is…

Unique study reveals genetic spelling mistakes that increase the risk of common cancers

[Press release, 27 March 2013] More than 80 genetic ’spelling mistakes’ that can increase the risk of breast, prostate and ovarian cancer have been found in a large, international research study within the framework of the EU Network COGS. For the first time, the researchers also have a relatively clear picture of the total number of genetic alterations that can…

Launching Karma Normal to study mammographic density in healthy women

In a substudy to Karma, scientists will study why it is more common among women with high mammographic density to develop breast cancer. The study will investigate breast tissue biopsies from women with low breast density and compare this with biopsies from women with dense breasts. Karma Normal is a collaboration between researchers at the…

50,000 women participates in the Karma study

Breast cancer has steadily increased over the past 40 years. In Sweden, one woman per hour is diagnosed with breast cancer and every six hours a woman dies from the disease. The need to prevent the onset of breast cancer is high. Therefore researchers at the Karolinska Institute in collaboration with four hospitals in Sweden…

High-throughput mammographic density measurement: a tool for risk prediction of breast cancer

Mammographic density (MD) is a strong, independent risk factor of breast cancer, but measuring MD is time-consuming and reader-dependent. Objective MD measurement in a high-throughput fashion would enable its wider use as a biomarker for breast cancer. We use a public domain image processing software for the fully automated analysis of MD and penalised regression…

The genomic and transcriptomic architecture of 2,000 breast tumours reveals novel subgroups

The elucidation of breast cancer subgroups and their molecular drivers requires integrated views of the genome and transcriptome from representative numbers of patients. We present an integrated analysis of copy number and gene expression in a discovery and validation set of 997 and 995 primary breast tumours, respectively, with long-term clinical follow-up. Inherited variants (copy…

19p13.1 is a triple negative-specific breast cancer susceptibility locus

The 19p13.1 breast cancer susceptibility locus is a modifier of breast cancer risk in BRCA1 mutation carriers and is also associated with risk of ovarian cancer. Here we investigated 19p13.1 variation and risk of breast cancer subtypes, defined by estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) status, using 48,869…
