The standard treatment for advanced metastatic prostate cancer (PCa) is androgen deprivation therapy (ADT). And even if this is efficient in the short term, 1/3 of PCa will become resistant to ADT and develop castration-resistant prostate cancer. A new study, by Karolinska Institutet and others, shows that estrogen receptor β (ERβ) agonists together with ADT could be considered useful in the treatment.

While the drug tamoxifen reduces the risk of developing breast cancer and prevents recurrence, the side-effects cause many women to discontinue their treatment. A study involving researchers at Karolinska Institutet in Stockholm has now found that a much lower dose than the standard produces a good effect with fewer adverse reactions in women who have yet to enter the menopause. The study, which has been published in the Journal of Clinical Oncology, can play a significant role in the treatment.

Using artificial intelligence and mobile digital microscopy, researchers hope to create screening tools that can detect precursors to cervical cancer in women in resource-limited settings. A study led by researchers at Karolinska Institutet and University of Helsinki now shows that AI screenings of pap smears carried out with portable scanners were comparable to analyses done by pathologists. The results are published in the journal JAMA Network Open.

Disorders of the cells’ energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on mitochondrial function to find future treatments. A new study involving researchers at Karolinska Institutet shows how an important molecule inside the mitochondria affects their function in mice and fruit flies. The study, which is published in Science Advances, adds valuable knowledge on formerly relatively unexplored protein modifications.

Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care. The research is published in Nature Communications.

A subset of immune cells called gamma delta T cells are associated with increased survival in patients with advanced ovarian cancer, researchers at Karolinska Institutet report in the scientific journal Science Translational Medicine. The findings suggest that promoting gamma delta T cell responses may be a therapeutic option for ovarian cancer, researchers say.

The ability of our skin to protect us from chemicals is something we inherit. Some people are less well-protected which could imply an increased risk of being afflicted by skin disease or cancer. A new study from Karolinska Institutet that has been published in Environmental Health Perspectives shows how the rate of uptake of common chemicals is faster in people with a genetically weakened skin barrier.

Treatment with the inhibitors stopped cancer cells from proliferating and reduced tumour growth in mice, without significantly affecting healthy cells.

The blood is the main source of studies on the immune system, despite the fact that most diseases are combated by immune cells in the body’s tissues. A new study from Karolinska Institutet and the University of Pennsylvania has identified which immune cells patrol the human body’s tissues and circulate back into the blood. The study, which is published in Cell, shows that not all T cells do this – some are found mostly in the blood where they constitute a unique part of our immune system.

Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is a malignant disease characterized by unique geographic distribution endemic to southern China, Southeast Asia, and the Middle East/North Africa. It is known that the interaction of Epstein-Barr Virus infection, environmental and lifestyle factors, and genetic susceptibility, contributes to NPC carcinogenesis.

Immunotherapy for cancer has made great advances and many patients can now receive effective treatments that were not available ten years ago. However, there are certain types of cancer that do not respond to existing immunotherapy. A study from Karolinska Institutet in Sweden published in Proceedings of the National Academy of Sciences (PNAS) reports on a new kind of immunotherapy that gives hope of more treatment options for cancer in the future.

Women with breast cancer whose eggs or ovarian tissue were frozen had more children after their diagnosis than women who did not undergo fertility preservation using those methods before start of cancer treatment. That is according to a study by researchers at Karolinska Institutet in Sweden, published in JAMA Oncology. According to the researchers, the result highlights the importance of reproductive counseling and fertility preservation for women who are diagnosed with cancer at a young age.

Researchers at Karolinska Institutet have been awarded a grant of SEK 290 million from the Swedish Cancer Society, meaning that over one third of the total grant of SEK 709 million, divided amongst eleven universities, is going to cancer research at KI.

The findings, from researchers at Karolinska Institutet in Sweden and MD Anderson Cancer Centre in Texas, ignite hope of novel treatment strategies against this disease. The study is published in the journal Cancer Research.

People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers at Karolinska Institutet in Sweden have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system’s cytotoxic T cells and thereby improves their ability to attack cancer cells. The study is published in the journal eLife.

A comprehensive comparison of cancer survival between the Nordic countries shows improvements for all countries over time with previously observed differences attenuated. The reasons for these improvements are likely multifactorial. Previous studies comparing cancer survival between the Nordic countries have found marked differences, with a notably poorer survival in Danish patients.

Women vaccinated against HPV have a significantly lower risk of developing cervical cancer, and the positive effect is most pronounced for women vaccinated at a young age. That is according to a large study by researchers at Karolinska Institutet in Sweden published in New England Journal of Medicine.

Women receiving fertility-sparing surgery for treatment of borderline ovarian tumours were able to have children, a study from Karolinska Institutet in Sweden published in Fertility & Sterility shows. Natural fertility was preserved in most of them and only a small proportion required assisted reproductive treatment such as in vitro fertilization. Survival in the group was also as high as in women who had undergone radical surgical for treatment of similar tumours.

Researchers at Karolinska Institutet and Karolinska University Hospital in Sweden have compared the ability of three different artificial intelligence (AI) algorithms to identify breast cancer based on previously taken mammograms.

For a few years, researchers at Karolinska Insititutet and several other universities have been working on building a digital tool which will make global genomic data easily available as support for treatment decisions.

The risk of developing more than one skin melanoma over a ten-year period has seen a ten-fold increase in Sweden since the 1960s, a new study by researchers at Karolinska Institutet and Lund University published in The Journal of the National Cancer Institute reports. The researchers suspect that the increase is due to a change in holiday customs with more active sunbathing and overseas trips to southern climes.

Patients with low income have a higher risk of death following surgery for lung cancer compared with patients with high income. The association remains even after taking prevalence of common comorbidities, and other factors that are known to influence the risk of death, into account. This is according to a study published in the journal Thorax by researchers at Karolinska Institutet in Sweden.
