Despite significant advances, mortality from brain tumors remains high with five-year survival rates of 36%, according to the National Cancer Institute. More accurate diagnoses might improve the situation, but tissue biopsies are invasive and can miss important information about a tumor’s make-up. Imaging-based methods, meanwhile, do not offer sufficient sensitivity and resolution. Now, researchers reporting …
Computer engineers and radiologists at Duke University have developed an artificial intelligence platform to analyze potentially cancerous lesions in mammography scans to determine if a patient should receive an invasive biopsy. But unlike its many predecessors, this algorithm is interpretable, meaning it shows physicians exactly how it came to its conclusions. The researchers trained the …
Consumption of a diet rich in healthy plant-based foods is associated with a reduced likelihood of having an elevated PSA level, new research suggests. “This finding may be incorporated into the shared-decision making process with patients to promote healthier lifestyle choices to reduce the likelihood of prostate biopsy and potential treatment-related morbidity,” a team led …
Artificial intelligence tools and deep learning models are a powerful tool in cancer treatment. They can be used to analyze digital images of tumor biopsy samples, helping physicians quickly classify the type of cancer, predict prognosis and guide a course of treatment for the patient. However, unless these algorithms are properly calibrated, they can sometimes …
A recent study by Nagoya University researchers revealed that microRNAs in urine could be a promising biomarker to diagnose brain tumors. Their findings, published in the journal ACS Applied Materials & Interfaces, have indicated that regular urine tests could help early detection and treatment of brain tumors, possibly leading to improved patient survival. Early diagnosis …
Nano-sized particles have been engineered in a new way to improve detection of tumors within the body and in biopsy tissue, a research team in Sweden reports. The advance could enable identifying early stage tumors with lower doses of radiation. In order to enhance visual contrast of living tissues, state-of-the-art imaging relies on agents such …
Most patients with early breast cancer may be able to safely skip chemotherapy thanks to 21 gene testing performed on biopsy samples, as published in the New England Journal of Medicine. In this groundbreaking study results suggest that about 70% of patients diagnosed with common forms of early breast cancer can safely avoid chemotherapy …
