Gene can predict aggressive prostate cancer at diagnosis — ScienceDaily

The results reported in the journal of Clinical Cancer Research, a publication of the American Association of Cancer Research, indicate the KLK3 gene — a gene on chromosome 19 responsible for encoding the prostate-specific antigen (PSA) — is not only associated with prostate cancer aggression, but a single nucleotide polymorphism (SNP) on it is more apparent in cancer patients with GS7. Researchers have linked Gleason score, an important predictor of prostate cancer outcomes, to several clinical end points, including clinical stage, cancer aggression and survival. …

Gene can predict aggressive prostate cancer at diagnosis

The results reported in the journal of Clinical Cancer Research, a publication of the American Association of Cancer Research, indicate the KLK3 gene — a gene on chromosome 19 responsible for encoding the prostate-specific antigen (PSA) — is not only associated with prostate cancer aggression, but a single nucleotide polymorphism (SNP) on it is more apparent in cancer patients with GS7. Researchers have linked Gleason score, an important predictor of prostate cancer outcomes, to several clinical end points, including clinical stage, cancer aggression and survival. There has been much research associated with prostate cancer outcomes as well as GS7 prostate cancers, which is an intermediate grade of cancer accounting for 30 to 40 percent of all prostate cancers. “This is the first report that I am aware of that indicates a genetic variant can stratify GS7 prostate cancer patients,” said Jian Gu, Ph.D., associate professor at MD Anderson, and a key investigator on the study. …

No apparent link between sleep apnea and cancer: Large study

Studies have postulated that obstructive sleep apnea may be linked to cancer because of low levels of oxygen in the blood. “There is a need for a sufficiently large cohort study with a long enough follow-up to allow for the potential development of cancer that adjusts for important potential confounders, examines common cancer subtypes and has a rigorous assessment of both obstructive sleep apnea and cancer,” writes Dr. Tetyana Kendzerska, Institute for Clinical Evaluative Sciences (ICES) and Women’s College Hospital, University of Toronto, Toronto, Ont., with coauthors. To understand whether obstructive sleep apnea is associated with cancer development, researchers undertook a study of 10 149 patients with the disorder who underwent a sleep study between 1994 and 2010. …

Common, hard-to-treat cancers: Potential new targeted therapies

“Cancer relapses and treatment resistance have always been among the most daunting challenges in cancer care,” said press briefing moderator Gregory Masters, MD, FACP, ASCO Expert and a medical oncologist at the Helen F. Graham Cancer Center in Newark, Delaware. “The good news is that genomic medicine is helping to overcome these challenges by revealing new ways to target a cancer cell’s inner workings. …

Immune therapy might be effective for multiple myeloma

The researchers modified a type of human immune cell — called T lymphocytes, or T cells — to target a molecule called CS1, which is found on more than 95 percent of myeloma cells, and to kill the cells. The researchers grew the modified cells in the lab to increase their numbers and then injected them into an animal model where they again killed human myeloma cells. The findings were published in the journal Clinical Cancer Research…

Harnessing power of immune system for therapies against cancer

The new studies find high activity with investigative drugs for advanced melanoma, and show for the first time that ipilimumab, a treatment already approved for advanced melanoma, can substantially decrease the risk of melanoma recurrence in certain patients with earlier-stage disease. In addition, another small trial reports that a one-time, personalized immunotherapy treatment induces complete and long-lasting remissions in a small number of women with advanced cervical cancer — a disease with little to no effective treatment options. …
