Tool helps guide brain cancer surgery

The Purdue-designed tool sprays a microscopic stream of charged solvent onto the tissue surface to gather information about its molecular makeup and produces a color-coded image that reveals the location, nature and concentration of tumor cells. “In a matter of seconds this technique offers molecular information that can detect residual tumor that otherwise may have been left behind in the patient,” said R. Graham Cooks, the Purdue professor who co-led the research team. …

Rare form of tongue cancer suggests screening vigilance

A 65-year-old male patient with a history of chronic alcoholism complained of an odd, painless white growth over his tongue. Doctors at the Government Medical College in Latur, India were intrigued when they identified the hard white growth as a rare case of spindle cell carcinoma. Spindle cell carcinoma is an aggressive variant of squamous cell carcinoma. These tumors get their name from their distinctive spindle-shaped cells, readily detectable by immunohistochemistry…

New prostate cancer blood test now available in the U.S. — ScienceDaily

The most widely used screening test for prostate cancer is currently the PSA test, which measures the blood’s level of PSA — a protein that is naturally produced by the prostate gland and is typically increased when cancer is present. However, it is widely recognized that PSA results can often indicate the possibility of prostate cancer when none is present. “The PSA test is based on the fact that men with higher levels of the PSA protein are more likely to have prostate cancer,” said William Catalona, MD, principal investigator on the Prostate Health Index clinical study and urologist at Northwestern Medicine and director of the Clinical Prostate Cancer Program at the Robert H. …

Cancer study maps decade of discovery to potential anticancer agent — ScienceDaily

“What began with the question ‘what makes a particular aggressive form of breast cancer cells keep growing?’ turned into 10 years of systematic research to identify the enzyme PLK4 as a promising therapeutic target and develop a small molecule inhibitor to block it,” says Dr. Mak, Director of The Campbell Family Institute for Breast Cancer Research at the Princess Margaret Cancer Centre, University Health Network. …

Genetic profile predicts which bladder cancer patients will benefit from early chemotherapy — ScienceDaily

During the study, 36 patients with muscle-invasive bladder cancer received chemotherapy before surgery, consisting of an accelerated regimen of methotrexate, vinblastine, doxorubicin, and cisplatin (AMVAC). By the time surgery rolled around, 14 patients appeared cancer-free. All but one of these patients carried mutations in at least one of three specific genes; none of these mutations were present in any of the people who still harbored traces of cancer after AMVAC. …
