Molecular pathology in Europe: in search of standardization

Tackling standardization of molecular pathology at a European level remains a major challenge, according to speakers at the 35th European Congress of Pathology in Dublin. One leading expert warned it would be ‘very difficult’ to achieve, though the session also heard about potential solutions such as educational steps to consistently train future pathologists at a high and consistent level.

Liquid biopsy vs. tissue biopsy: Getting the best of both worlds

Tissue biopsy and liquid biopsy can increasingly be used as complementary or alternative approaches, with advantages and limitations to each. While speakers at the recent 35th European Congress of Pathology in Dublin were quick to highlight that liquid biopsy was not about to replace tissue biopsy, the focus looked at the benefits and challenges of each through the lens of four expert speakers.

Taking a closer look at breast cancer

Breast cancer has no “one size fits all” therapy approach: subtypes differ significantly in malignancy, progression, and treatment response. Therefore, the more is known about the type of carcinoma in a patient, the better the outcome. At the annual scientific EUSOBI meeting in Valencia, Dr Ramona Woitek pointed out the potential of novel imaging techniques and computational image analysis…

MRI breast cancer screening of high-risk women: benefits outweigh drawbacks

Breast MRI is increasingly being used as a primary breast cancer screening exam for young women. It brings benefits in women with dense breasts, who are at an elevated risk of developing breast cancer. The technique is also being ordered as a supplemental screening exam following mammography or breast ultrasound for women of all ages at high risk. But use of breast MRI as a screening tool is…

Fluorescence-guided surgery identifies breast cancer in margins

Breast surgery is a traumatic experience for a woman, no matter whether breast-conservation surgery (BCS) or a mastectomy. Trauma levels are greatly enhanced, if pathological evaluation findings of an excised breast tumour following a lumpectomy suggest that additional cancer may still be in the margins, and a second surgical procedure is required. A new system with the ability to accurately…

Covid-19 and sex: higher mortality of male patients

The Covid-19 pandemic has affected scientific research in numerous ways – for example by highlighting knowledge gaps in gender medicine. In many studies differences in morbidity and mortality between women and men surfaced incidentally. While the extent and causes of these differences remain largely unexplored, the preliminary insights confirm the need for further research.

Artificial intelligence in healthcare: not always fair

Machine learning and AI are playing an increasingly important role in medicine and healthcare, and not just since ChatGPT. This is especially true in data-intensive specialties such as radiology, pathology or intensive care. The quality of diagnostics and decision-making via AI, however, does not only depend on a sophisticated algorithm but – crucially – on the quality of the training data.

Detecting and measuring nanoplastics in the blood stream

Plastics are a part of everyday life, and an increasingly concerning factor of global environmental pollution. They also have infiltrated our bodies as microparticles (MPs) and nanoparticles (NPs), found even in placentas supporting foetal life. And they are in our blood. Now, researchers in Spain have developed a new method to detect and measure nanoparticles in human peripheral blood that is…

The need for breast imaging for transgender patients

The need for breast cancer screening of transgender individuals has been a topic of uncertainty until recently, due to lack of reliable patient data, consensus by radiologists, published research, and recommended guidelines. A 2021 survey of Society of Breast Imaging (SBI) members revealed that ‘breast radiologists differ in their practice and knowledge regarding screening of transgender…

Detecting breast cancer via electrical currents in the skin

Mammograms are a safe, effective way to detect the presence of breast cancer in women. But doctors recommend most females should start getting mammograms after the age of 40 in part because the procedure involves small doses of ionizing radiation. While the risk of getting breast cancer is higher for older people, it can strike at any age. Studies show that 5% to 7% of females with breast cancer…
