The University of Pittsburgh Cancer Institute has discovered three proteins present in liver tissue from colon cancer patients that are not found in normal liver tissue. The findings hold promise for developing a more sensitive tumor marker for early detection and predicting potential recurrence.
A research team led by Wake Forest and Johns Hopkins universities found that mutations in the MSR1 gene are associated with an increased risk of aggressive prostate cancer, particularly in African-American men. The study identified seven potentially important mutations of the MSR1 gene, including one that leads to rapid metastasis.
A review highlights the association between excess body weight and increased cancer risk, particularly in colon, breast, endometrium, oesophagus, and kidney. The study suggests that alterations in hormone metabolism may play a role in this link, emphasizing the importance of weight management for cancer prevention.
Researchers engineered a virus to target prostate-specific antigen, appearing as 'hot spots' in primary tumors and distant metastases. This method could deliver toxic treatments directly to prostate cancer cells, killing them while sparing surrounding healthy tissue.
A new radium isotope, radium223, has shown promise in treating skeletal metastases with less damage to bone marrow compared to traditional treatments. The isotope is incorporated into skeletal tissue via osteoclasts and emits radiation that kills cancer cells, providing pain relief and potentially improving quality of life.
Cancer cells invading blood vessels and lymph vessels allows them to grow anew in other parts of the body. NFAT protein is found to be contributing to aggressive behavior of cancer cells and associated with alpha 6 beta 4 integrin, a hallmark of metastatic tumors.

Cancer patients' dietary needs vary according to disease stage, with underweight patients benefiting from fatty foods and those well-recovering advised on traditional healthy diets. The study found that nearly two-thirds of patients changed their eating habits since diagnosis, with most taking nutritional supplements.
A new study found that PET scans changed clinical management for 60% of women with recurrent breast cancer, including shifting from surgery to radiation therapy or medical treatment. The scan also significantly impacted disease staging, upstaging 28% and downstaging 8%, leading to more patients being classified as stage IV.
A team of researchers at Penn State's College of Medicine has isolated and characterized a gene, BRMS1, that plays a role in blocking tumor cells' ability to spread. The gene provides a target for developing therapies to keep cancer localized and may aid in proper diagnosis.
A Phase III study found that a combination of histamine dihydrochloride and lower doses of interleukin-2 improved overall survival, increased survival rates at 12, 18, and 24 months, and reduced time-to-disease-progression compared to IL-2 alone. The treatment was well-tolerated and had substantially less toxicity.
Researchers found two protein biomarkers, cIAP-1 and XIAP, that correlate with distant metastasis-free survival in prostate cancer patients. Elevated levels of these proteins were associated with a higher risk of relapse after radiation therapy.
A new treatment combination of paclitaxel and carboplatin has shown encouraging results in a clinical trial, achieving a 62% response rate and a projected 72% one-year survival rate. The treatment, which is compatible with prior anthracycline therapy, offers additional benefits for women with metastatic breast cancer.
A new test developed by USC scientists and colleagues can accurately detect hidden breast cancer cells in lymph nodes, improving the detection of metastases. This breakthrough enables customized treatments tailored to individual patients' characteristics, such as tumor size and hormone receptor status.
A new study developed a simple method to assess the risk of deadly metastatic cancer in men after prostate removal. The chart uses three common measures, including Gleason score and PSA doubling time, to pinpoint the risk for developing metastatic cancer.
A team of researchers at Duke University Medical Center has mapped a region of human chromosome 11 and identified a new gene, RRM1, that is believed to be responsible for the aggressive nature of lung cancer. The gene's role in DNA production and repair makes it a potential therapeutic target for improving treatment outcomes.
A study by Weizmann researchers suggests that a cell-suicide gene called DAP-kinase can prevent metastasis in cancer. The gene's proper functioning is essential for cells to die during different stages of metastasis, and its loss or malfunction can lead to unwanted cell proliferation and tumor development.
Researchers at Penn State have discovered a new gene called KiSS-1 that suppresses the metastasis of melanoma in laboratory mice. The gene, located on chromosome 1, reduces the spread of melanoma by at least 50 percent of the time and may be the most potent gene to block or suppress metastasis in human cancer.
Researchers at UCLA's Jonsson Comprehensive Cancer Center are testing the safety and effectiveness of TNP-470, an experimental drug that prevents tumor growth by blocking the formation of new blood vessels.
