The use of molecular biomarkers in minimally invasive sampling opens a promising perspective for the early detection of endometrial cancer. This is the conclusion reached by the members of Screenwide research group, formed by researchers from the Bellvitge Biomedical Research Institute (IDIBELL) and the Catalan Institute of Oncology (ICO-Hospitalet).

Using human cancer cells, tumor and blood samples from cancer patients, researchers at Johns Hopkins Medicine have uncovered the role of a neurotransmitter in the spread of aggressive cancers. Neurotransmitters are chemical "messengers" that transmit impulses from neurons to other target cells.
To explain a person's actions in the present, it sometimes helps to understand their past, including where they come from and how they were raised. This is also true of tumors. Delving into a tumor's cellular lineage, a Ludwig Cancer Research study shows, can reveal weaknesses to target for customized therapies.
The findings, detailed in the April 24 issue of the journal Nature, also illustrate how knowledge of the biochemistry and microenvironment of the tissue from which a tumor arises can help predict the genetic alterations its cancer cells are likely to undergo.
Bottom Line: Six factors were associated with invasive recurrence of breast cancer after a diagnosis of ductal carcinoma in situ (DCIS), according to data from a meta-analysis.
Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
A remarkable recent increase in the diagnosis of vocal-cord cancer in young adults appears to be the result of infection with strains of human papilloma virus (HPV) that also cause cervical cancer and other malignancies. Investigators from Massachusetts General Hospital (MGH) describe finding HPV infection in all tested samples of vocal-cord cancer from 10 patients diagnosed at age 30 or under, most of whom were non-smokers.
A tumor-specific vaccine combined with an immune checkpoint inhibitor shrank tumors in one third of patients with incurable cancer related to the human papilloma virus (HPV) in a phase II clinical trial led by investigators at The University of Texas MD Anderson Cancer Center and reported in JAMA Oncology.
A study conducted by researchers at Washington University School of Medicine suggests that it may be possible to use an eye test to screen people for their risk of developing Alzheimer’s disease.
Using a non-invasive eye exam, the researchers detected signs of Alzheimer’s in older people before they had developed any symptoms of the disease.
This technique has great potential to become a screening tool that helps decide who should undergo more expensive and invasive testing for Alzheimer's disease prior to the appearance of clinical symptoms."
Results of the European multi-center study of Bladder EpiCheck™ urine test, supporting reduction of invasive procedures, were published in the European Urology Oncology journal
A four-protein biomarker blood test improves lung cancer risk assessment over existing guidelines that rely solely upon smoking history, capturing risk for people who have ever smoked, not only for heavy smokers, an international research team reports in JAMA Oncology.
When it comes to diagnosing a condition in which the plasma cells that normally make antibodies to protect us instead become cancerous, it may be better to look at the urine as well as the serum of our blood for answers, pathologists say.
The condition is monoclonal gammopathy, in which immune cells called plasma cells start making just one immunoglobulin, or antibody, instead of their usual vast array. The result can be the cancer multiple myeloma.
