SAN DIEGO-More than 70% of advanced pancreatic patients derived some clinical benefit when treated with nanoparticle albumin-bound (nab) paclitaxel (Abraxane) and gemcitabine (Gemzar), in a phase I study reported at the 2008 American Association of Cancer Research meeting (abstract 4179).

SAN DIEGO-The body’s immune system can be directed to shrink tumors and prevent new ones in a variety of tumor types, according to investigators who described new cellular strategies and vaccines at the 2008 American Association for Cancer Research annual meeting.

GlaxoSmithKline (GSK) recently announced the submission of a new drug application to the US Food and Drug Administration for casopitant (Rezonic, Zunrisa), a novel, investigational NK-1 receptor antagonist, for the prevention of chemotherapy-induced nausea and vomiting (CINV) as an add-on therapy to the standard dual therapy of a 5-HT3 receptor antagonist, such as ondansetron (Zofran), and dexamethasone.

Researchers report that zoledronic acid (Zometa), a drug used to treat bone metastases and recently approved to treat osteoporosis, also lowers the risk of breast cancer recurrence in premenopausal patients with early-stage disease who have undergone surgery and are receiving ovarian suppression and hormone therapy. All women in this multicenter phase III trial had cancer that was estrogen-receptor– or progesterone-receptor–positive. The study was presented at the ASCO plenary session by lead author Michael Gant, md, professor of surgery at the Medical University of Vienna and the president of the Austrian Breast and Colorectal Cancer Study Group, or ABCSG (abstract LBA4).

CHICAGO-The first clinical trial targeting stem cells in breast cancer is underway with the potential to revolutionize therapeutic targets, according to one of the pioneers in stem cell research. The stem cell hypothesis suggests that stem cells drive tumor invasion and metastases. “Cytotoxic chemotherapies have not been very effective for patients with advanced cancer,” Max Wicha, MD, told ONI. “I think the stem cell model is a potential explanation for why we haven’t done better in treating cancer.”

Screening ultrasound paired with mammography upped breast cancer detection in high-risk women with dense breasts, but the combination also caused a spike in the number of false positives, according to an update of the ACRIN 6666 trial. These results, along with other barriers, may render ultrasound less attractive than MRI in this patient population, commented a breast imaging expert.

SAN DIEGO-For women with ductal carcinoma in situ, it may be possible to deliver chemotherapy intraductally, thus providing a less toxic means of treatment, according to a feasibility study spearheaded by Susan Love, MD, of UCLA’s David Geffen School of Medicine. Dr. Love presented her research at the 2008 American Association for Cancer Research annual meeting (abstract LB-245).

GENEVA-Patients with NSCLC who received MAGE-A3 ASCI (antigen-specific cancer immunotherapeutic) had longer disease-free (HR 0.76) and overall survival (HR 0.81) than those who received placebo, although in this phase II study of 182 patients, the difference did not reach significance.

Preliminary results from two trials presented at the 44th Annual Meeting of ASCO in Chicago have consolidated the role of K-ras as a biomarker of nonresponse to cetuximab and panitumumab in metastatic colorectal cancer (mCRC). The phase III CRYSTAL and OPUS trials presented unplanned subgroup analyses of the correlation of K-ras status with response to therapy with first-line FOLFIRI or FOLFOX, respectively, with or without cetuximab in patients with mCRC. Both studies demonstrated a clear benefit with the addition of cetuximab in K-ras WT patients.

ROCKVILLE, Maryland-FDA has approved Progenics and Wyeth’s Relistor (methylnaltrexone bromide) subcutaneous injection for the treatment of opioid-induced constipation in patients with advanced illness who are receiving palliative care, when response to laxative therapy has not been sufficient.

With proton beam therapy centers proliferating in the United States, particularly for use in treating prostate cancer (see April 2008 ONI, page 1), the debate is heating up over the need for randomized clinical trials comparing proton beam therapy with conventional x-ray (photon) therapy in prostate and other cancers.

The recently opened Institute of Cancer “Octavio Frias de Oliveira,” in Brazil’s capital of São Paulo, is a state institution that will care for cancer patients from São Paulo as well as neighboring states, according to information provided by ONI Editorial Advisory Board member Paulo Hoff, MD, of The Medical School of the University of São Paulo.

Bertagnolli, MD (surgical oncologist); and Robert Langdon, Jr., MD (community oncologist). Mary-Claire King, PhD, who serves as the American Cancer Society Research Professor of Medicine and Genome Sciences, University of Washington, Seattle, will receive ASCO’s Science of Oncology Award for her work on the genomic localization of the BRCA1 gene.Patricia A. Ganz, MD, professor of health services and medicine, UCLA, and director of the Division of Cancer Prevention and Control Research at the Jonsson Comprehensive Cancer Center, will receive the American Cancer Society Award at the ASCO annual meeting. She will present a lecture on improving outcomes for cancer survivors.Nancy E. Davidson, MD, professor of oncology and breast cancer research chair in oncology, Johns Hopkins University School of Medicine, Sidney Kimmel Comprehensive Cancer Center, was honored with the 11th Annual AACR-Women in Cancer Research-Charlotte Friend Memorial Lectureship at the recent AACR annual meeting, for her accomplishments in translational cancer science, including pivotal discoveries regarding the epigenetic regulation of estrogen receptors.John Mendelsohn, MD, president of The University of Texas M.D. Anderson Cancer Center, was awarded AACR’s Dorothy P. Landon Prize for his pioneering translational research on targeting signal transduction mediated by tyrosine kinases that led to the development of C225 (cetuximab).The Stanford University School of Medicine has received a $43.58 million grant from the California Institute for Regenerative Medicine, toward funding a new building that will house stem cell research on campus, to be called Stanford Institutes of Medicine 1 (SIM1). Irving Weissman, MD, director of Stanford University’s Stem Cell Biology and Regenerative Medicine Institute, said that “SIM1 will bring together a group of scientists interested in all aspects of stem cell biology and cancer stem cell research.”

Integrative oncology, the synthesis of gold-standard care and evidence-based complementary modalities, deals not only with the patient’s tumor, but also with her physical and emotional needs and with the relevant cultural, scientific, and policy issues. This synthesis was one of Marty Abeloff’s main professional goals.

SAN DIEGO-A novel compound, KXO1 (KX2-391) that targets Src family kinases (SFK) inhibited the growth of many cancer cell types in culture and inhibited the growth of human colon cancer cells in animal models, Irwin H. Gelman, PhD, reported at AACR 2008 (abstract 4983).

A new study using x-ray crystallography has shown that the investigational agent matuzumab binds to EGFR at a different site than cetuximab (Erbitux).

Researchers at Dana-Farber have found that normal myoepithelial cells, which form part of the lining of the milk ducts, suppress fibroblasts that promote tumor growth and invasion, but when certain genes in the myoepithelial layer become under- or overactive, the layer breaks down and disappears, enabling tumor cells to spread.

GENEVA-A free online database brings together data on all of the known somatic mutations in EGFR, coupled with data on the response of NSCLCs treated with tyrosine kinase inhibitors, Samuel Murray, PhD, of Metropolitan Hospital, Athens, Greece, reported at the 1st European Lung Cancer Conference (abstract 750).
