NYU Cancer Institute Experts Present At The 101st Annual Meeting Of The American Association Of Cancer Research
April 21, 2010 (New York, NY) - Experts from The Cancer Institute at NYU Langone Medical Center presented new research findings at the 101st Annual Meeting of the American Association of Cancer Research in Washington, DC. The conference was held from April 17-21, 2010, and scientists from the Cancer Institute discussed various topics such as the role of MicroRNAs as mediators of melanoma metastasis to the brain and the use of radiation and chemotherapy before breast cancer surgery.
Identification of miRNAs that Contribute to Melanoma Brain Metastasis
Authors: Avital Gaziel and Eva Hernando
Brain metastasis occurs in a large proportion of metastatic melanoma patients and is associated with a dismal prognosis. The molecular mechanisms that govern melanoma traveling to the brain remain poorly understood. However, scientists at NYU Langone Medical Center have found that specific MicroRNAs (miRNAS) may be important mediators of melanoma metastasis to the brain. Using an in vivo model of melanoma brain metastasis, NYU Langone researchers confirm the capacity of specific miRNA alterations to promote melanoma cells' ability to reach the brain. These results may help expand the understanding of the mechanisms that control melanoma brain metastasis, potentially revealing novel therapies for patients whom no viable approaches are currently available.

Acrolein-deoxyguanosine DNA Adduct Formation and Lung Cancer
Authors: Yu Hu, William Rom, Harvey I. Pass, Moon-Shong Tang
Cigarettes smoke contains 1,000 to 10,000 times more of the chemicals acrolein (Acr) and crotonaldehyde (Crot) than polycyclic aromatic hydrocarbons (PAHs)-the first carcinogen discovered in cigarette smoke. The deposits of PAHS in the p53 gene, a gene that regulates cells and aids in tumor suppression, have long been shown to cause lung cancer in cigarette smokers. In this study, scientists found that the level of Crot in smokers with lung cancer is significantly higher than that in non-smokers with the disease - with the levels of Acr in smokers with lung disease just slightly higher than that in non smokers with the disease.

Preoperative Concurrent Paclitaxel and Radiation in Locally Advanced Breast Cancer (LABC): Five-year Outcomes of 105 Patients
Authors: Sylvia Adams, Martin Donach, Stella Lymberis, Baljit Singh, Tsivia Hochman, Judith D. Goldberg, Silvia C. Formenti
Patients with Locally Advanced Breast Cancer (LABC) or stage III breast cancer, usually receive only chemotherapy prior to surgery -- then radiation after surgery. But a long term study by NYU Langone researchers has found there may be a benefit to using the chemotherapy drug paclitaxel in conjunction with radiation before surgery to improve 5 year survival outcomes. Researchers found that the 34 percent of patients studied had a pathological response with a 5-year estimated overall survival rate of 71.6 percent -- and an estimated 5 year disease free survival rate of 61.4 percent. This novel approach presents another option for patients with LABC and a chance for significantly improved 5 year estimated overall survival.

Inhibition of Transforming Growth Factor β (TGFβ) Increases the Therapeutic Benefit of Radiotherapy in a Murine Mammary Tumor Model
Authors: Sophie F. Bouquet, Karsten Pilones, Sandra Demaria, Mary Helen Barcellos-Hoff
Transforming growth factor beta, or TGFß, is a molecule found in every cell of the human body that safeguards our cells from disease and tissue damage. However, during radiation therapy for cancer, TGFß is altered and can cause damage to DNA - affecting cell signaling which can in turn suppress the immune system and promote tumor growth. Researchers at NYU Langone Medical Center investigated the benefits of using an injectable TGFβ inhibitor to improve the therapeutic effects of radiotherapy in a highly metastatic breast cancer mouse model. Study results show, that the use of a TGFß inhibitor in combination with radiotherapy, increases the response of cancer cells to radiation. In addition, the TGFß inhibitor served as a protective benefit for normal tissue. NYU Langone researchers believe that the use of TGFß inhibitors during radiotherapy for breast cancer may help improve patient outcomes with the potential for curing the disease.
