Scientists have developed nanowire arrays that can detect multiple cancer markers with near-perfect selectivity. These devices can test a mere pinprick of blood in minutes, providing immediate scans and potentially tracking patients' health as treatment progresses.
The blood test aims to identify individuals with improper control of the growth-promoting gene insulin-like growth factor 2 (IGF-2), which is associated with a higher risk of colon cancer. If successful, the test could help monitor those who need invasive colonoscopy or suggest dietary changes to reduce their risk.
A new protein targets tumor vasculature by inducing coagulation when administered systemically, delaying tumor growth and producing some tumor regressions. The treatment shows promise for cancer therapy, adding a powerful punch to the fight against cancer.
A study found that patients with high circulating endothelial cell counts before treatment were more likely to have growing tumors, while those with low counts remained stable. This test may predict patient outcomes and survival, allowing doctors to tailor treatment and spare unnecessary side effects.

A study found that 23% of zoo workers handling primates showed reactivity to the SV40 virus, but most reactions were likely due to cross-reactivity with other polyomaviruses. The study suggests occupational exposure to SV40 among those working closely with nonhuman primates.
A recent study found that the Ras protooncogene induces inflammation via CXCL-8, a key factor in tumor growth and angiogenesis. Inhibition of CXCL-8 function led to decreased tumor angiogenesis, highlighting its potential as an anticancer therapeutic target.
Researchers found a link between chronic allergic stimulation and an increased risk of leukemia and non-Hodgkin's lymphoma in adults. Childhood eczema also appeared to increase the risk of this condition, although its impact is still relatively rare.
A team of researchers from MIT has identified three new carcinogens found in cigarette smoke as risk factors for bladder cancer in nonsmokers. The study, led by Professor Steven R. Tannenbaum, aimed to identify sources of exposure for non-smokers and highlights the importance of preventing cancer rather than treating it.
Researchers at Temple University's Sbarro Institute developed a new blood test that uses CDK9/CYCLIN T1 expression to accurately diagnose lymphoma cancer types and stages. The study, published in the Journal of Pathology, found that analyzing these molecules in a blood sample can pinpoint the presence of lymphoma with high accuracy.
Anal cancer rates have increased by 160% in men and 78% in women over the past 30 years, with African-American men showing a particularly sharp increase. Human papillomavirus (HPV) infection is necessary for most cases of anal cancer, but smoking also plays a significant role.
A Phase II clinical trial suggests that RAD001, targeting mTOR, can decrease uterine tumor size in recurrent endometrial cancer. The treatment offers new hope for patients with advanced and recurrent cases, which account for about 7,000 deaths annually.
A new study by Dr. Thomas Walle found that resveratrol, a widely sold dietary supplement, is unlikely to have an effect on breast and prostate cancers when consumed in the diet or as a supplement. However, it may still prevent cancers along the aerodigestive tract, suggesting further research is needed.
Researchers developed a biomarker to detect HBV mutations that speed up liver cancer development. Studies found HBV mutations predicted major liver disease, including liver cancer, up to eight years before diagnosis.
Researchers discovered that BCR/ABL oncogene blocks normal DNA repair mechanism, leading to genetic mutations and blast crisis. This breakthrough may lead to long-term treatment for chronic myelogenous leukemia, a fatal blood cancer affecting people over 40.
Researchers at Dana-Farber Cancer Institute have discovered that the MLL gene is necessary for the development of master stem cells that generate all mature blood cells. The study suggests that MLL is part of a select set of genes required for all definitive blood lineages in the embryo.
A new study by St. Jude/Mayo Clinic researchers found a direct link between the CBP gene and lymphoma development in mice, with the loss of CBP promoting T-cell lymphoma and cooperating with reduced p27Kip1 protein levels. The study suggests that CBP plays a role in cancer development despite normal p53 activity.
Researchers explored the potential of copper to control cancerous growth by depleting it of essential nutrients. Studies have shown that regulating copper levels can stop tumor growth, although no cures have been found yet, and further research is needed for a more comprehensive approach.
A study published in The Journal of the American Medical Association found that people with higher CRP levels were more likely to develop colorectal cancers over an 11-year period. Median CRP levels were higher among those who developed colon cancer, and inflammation was linked to increased risk without being mediated by diabetes.
Case Western Reserve University scientists identified a protein called clusterin that can signal cell distress and detect cancer. A simple blood test could potentially identify abnormal clusterin levels, indicating the presence of cancer.
Researchers at the University of Iowa have discovered a way to improve cancer immunotherapy by directing specific types of white blood cells to kill cancer cells. By using CpG ODN agents, doctors can gear up natural killer cells and granulocytes to work with antibodies to target cancer cells more effectively.
Researchers found that patients with smoking-related cancers had shorter telomeres than those without cancer, and that short telomeres were associated with a greater cancer risk. Smoking status significantly influenced the effect of short telomeres on cancer risk.
A new treatment, interleukin-11 (IL-11), has shown early promise in reducing the risk of infection in patients undergoing chemotherapy for blood cancer. Patients who received IL-11 experienced significantly fewer cases of bacterial infections compared to those who received a placebo.
Researchers discovered that the Id1 gene regulates angiogenesis in melanoma, breast, head and neck, brain, cervical, prostate, pancreatic, and testicular cancers by reducing thrombospondin-1 production. This reduction leads to increased tumor blood vessel formation.
A comprehensive periodontal examination can save lives by detecting undiagnosed protein S deficiency, a condition that causes thrombotic disorders and increases the risk of strokes and heart attacks. Early diagnosis is key to successful treatment outcomes and improved survival rates for patients with this condition.
A new computer-based algorithm identifies a distinct proteomic pattern that distinguishes malignant from benign tumours within the ovary with 100% sensitivity and 95% specificity. This technique may help screen for ovarian cancer in high-risk and general populations.
A new combination of MabThera and standard chemotherapy has shown a significant increase in overall survival rate and complete remission rates in patients with aggressive non-Hodgkin's lymphoma. This treatment offers hope for improved outcomes in this increasingly common form of blood cancer.
