Breast cancer remains a major cause of cancer-related mortality among women. Breast-conserving surgery (BCS), also known as lumpectomy, is the removal of the cancerous lump and a small margin of surrounding tissue. This procedure is typically advised for women with early-stage breast cancer or small tumors, as it conserves more of the breast tissue compared to a mastectomy. After undergoing BCS, it is critical to verify that all cancerous cells have been removed to decide if additional surgery is necessary. This verification involves a tumor margin assessment, which examines the edges of the excised tissue (tumor margins) to check for residual cancer cells. Conventionally, this assessment entails staining the tissue samples with dyes and inspecting them under a microscope to differentiate between healthy and cancer cells. However, new optical imaging techniques have emerged as quicker alternatives for conducting these assessments. A group of researchers from the United States, including members ...
For the second month in a row, the NHS has met the 28-day faster diagnosis target for cancer The NHS has announced, for the second month in a row, that it has met the 28-day faster diagnosis target for cancer as well as faster ambulance responses to call outs compared to March 2024. The announcement builds on targeted national support for NHS trusts in reducing variation across the country and speeding up diagnosis for patients, while also bringing down the backlog of patients waiting for diagnosis or treatment from the COVID-19 pandemic. New published data has shown that the number of patients waiting more than 62 days for care is now at its lowest ever since the end of April 2020, reducing by almost 20,000 patients since the post-pandemic peak. In addition, almost 77% of people referred or screened received a definitive diagnosis or were all clear within four weeks, ...

LAG-3 monoclonal antibody can block the LAG-3 ligand on the cell surface, enhance the secretion of cytokines and exert anti-tumor immunity. Pavelizumab is a PD-1 monoclonal ...
Anticancer drugs will be responsible for 90% of nearly 612,000 predicted US cancer deaths in 2024 Oregon Therapeutics and Lantern Pharma have entered into a strategic artificial intelligence (AI)-driven collaboration to optimise the development of a protein disulfide isomerase (PDI) inhibitor drug candidate for a variety of novel and targeted cancer indications. XCE853 is being developed by Oregon in various indications, including drug-resistant ovarian and pancreatic cancer, certain haematological cancers and several paediatric cancers, including central nervous system cancers. Nearly 612,000 deaths are predicted to occur in the US in 2024 due to cancer and resistance to anticancer drugs will be responsible for 90% of those deaths. Under the terms of the agreement, Lantern will receive equal intellectual property (IP) co-ownership and drug development rights in newly discovered biomarkers, novel indications, and pharmacological use strategies for XCE853, while Oregon is entitled to financial benefits resulting from the licensing of the ...
Johns Hopkins Medicine scientists have revealed a molecular pathway that lures cells down a path of genome duplication, a hallmark of cancer cells, which could potentially lead to new therapies and could stop the growth of cancers. Published in Science, the study reveals the consequences of molecules and enzymes triggering and regulating the process of making new cells out of the cells’ genetic material. Cells follow an orderly routine that begins with making a copy of their entire genome, followed by separating the genome copies and dividing the replicated DNA evenly into two “daughter” cells. When doing so, cells that are stressed can mistakenly run the risk of copying their genome again. Focusing on human cells that line breast ducts and lung tissue, scientists analysed thousands of images of single cells as they went through cell division and developed glowing biosensors to tag cyclin dependent kinases (CDKs), which play a ...
Lantern Pharma has entered into a partnership with Oregon Therapeutics for optimising the development of the cancer drug candidate, XCE853, through an AI-driven approach. XCE853 is an inhibitor of protein disulfide isomerase (PDI). The partnership will utilise RADR AI platform of Lantern to identify biomarkers and efficacy-linked signatures of XCE853 for precision development across solid tumours. Furthermore, this alliance will identify biomarker signatures that can aid in stratifying tumours that are most responsive to the drug and facilitate in the clinical development and patient selection in the future. Oregon focuses on developing XCE853 for a range of cancer indications, including drug-resistant ovarian and pancreatic cancers, certain haematological cancers, and several paediatric cancers, such as central nervous system (CNS) cancers. The collaboration aims to harness computational tools, including machine learning and large-scale molecular analysis, to streamline the development process. The partnership will integrate and interrogate a vast array of molecular, genetic, ...
Researchers from the Francis Crick Institute, the National Cancer Institute of the US National Institutes of Health and Aalborg University in Denmark have revealed that vitamin D encourages the growth of a type of gut bacteria in mice, which provides better cancer immunity. The study published in Science found that vitamin D increases the amount of Bacteroides fragilis, providing better immunity to cancer in mice with transplanted tumours. Cancer, including female breast, lung, bowel and prostate cancers, was responsible for more than 18 million new cases worldwide in 2020, according to Cancer Research UK. After giving mice a diet rich in vitamin D, researchers discovered they had better immune resistance to experimentally transplanted cancers and improved responses to immunotherapy treatment. Furthermore, this effect was seen when gene editing was used to remove a protein that binds to vitamin D in the blood and keep it away from tissues. Researchers found ...
Bladder cancer, including papillary tumours, is the ninth most common cancer type worldwide Researchers from ETH Zurich and University Hospital Basel have revealed new insights for cancer research when focusing on mechanical changes in tumour tissue after investigating the early stages of bladder cancer. Researchers aimed to understand what governs the direction in which bladder tumours grow and whether it plays a role in malignant and benign formations. Currently the ninth most common cancer type worldwide, bladder cancer occurs when cells in the bladder start to grow without control. Papillary tumours, long, slender benign or malignant tumours that grow from tissue that lines the inside of the organ, are usually easy to treat, while muscle-invasive bladder cancer, which spreads into the thick muscle of the bladder wall, requires surgical removal of the bladder. Similar to bronchioles in the lungs, researchers wondered whether molecular mechanisms could be responsible for creating the ...
A new editorial paper was published in Oncoscience (Volume 11) on April 22, 2024, entitled, “Exploring oncogenic driver molecular alterations in Hispanic/Latin American cancer patients: A call for enhanced molecular understanding.” In this new editorial, researcher Rafael Parra-Medina from Fundación Universitaria de Ciencias de la Salud and Instituto Nacional de Cancerología begins by discussing Latin America’s (LA) population -; a heterogeneous mix of Amerindian, African, and Caucasian ancestries with different proportions in different regions. Countries such as Argentina, Brazil, Colombia, Costa Rica, Uruguay, and Venezuela have a higher proportion of Caucasian while regions in Mexico, Perú, and Bolivia have a higher proportion of Amerindian ancestries. Although the overall incidence of cancer in Latin American countries is generally lower compared to high-income nations, the mortality rate is notably higher. “This disparity can be attributed to several factors, including smoking habits, diet quality, levels of physical activity, access to healthcare services, and ...
