Breast US finds cancer that mammo misses in at-risk pts
June 1st 2008Screening 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.
Intraductal chemotherapy appears feasible for DCIS patients
June 1st 2008SAN 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).
Stereotactic Body Radiotherapy in the Management of Painful Bone Metastases
Bone metastases are a common feature of many solid cancers, especially those originating from the prostate, breast, lung, kidney, melanoma, and other sites. Up to 80% of patients with these cancers will develop painful bony disease during the course of their disease.
Immunotherapy agent promising in NSCLC
May 24th 2008GENEVA-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.
Mutated ras as a Predictor of Response: Is It Ready for the Clinic?
May 15th 2008Preliminary 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.
Experts argue against need for phase III proton Rx trials
May 2nd 2008With 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.
Breast Cancer Risk Amplified by Additional Genes in Combination With Damaged BRCA Genes
May 2nd 2008Many women with a faulty breast cancer gene could be at greater risk of the disease due to extra risk-amplifying genes, according to research published recently in the American Journal of Human Genetics.
Martin Abeloff and the Quality-of-Life Movement
May 2nd 2008Integrative 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.
New compound inhibits Src family kinases
May 1st 2008SAN 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).
Myoepithelial cells lining milk ducts hold key to spread of DCIS
May 1st 2008Researchers 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.
Database lists somatic EGFR mutations
May 1st 2008GENEVA-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).
Smoke-free restaurant laws may discourage youths from smoking
May 1st 2008Young people who live in towns where regulations ban smoking in restaurants may be less likely to become established smokers, Michael Siegel, MD, MPH, of Boston University School of Public Health, and colleagues reported (Arch Pediatr Adolesc Med 162:477-483, 2008).
ESMO/ECCO to host combined meetings
May 1st 2008LUGANO, Switzerland-The European Society for Medical Oncology (ESMO) and the European Cancer Organisation (ECCO) (Brussels) have united forces to host a co-branded biennial multidisciplinary partnership meeting to provide “the best and most updated scientific data for everyone working in cancer,” the two organizations announced in a press release.
Two-stage hepatectomy for 'unresectable' liver mets
May 1st 2008ORLANDO-“Unresectable” colorectal cancer liver metastases may actually be resectable with a two-stage hepatectomy approach, Rene Adam, MD, PhD, of the Hospital Paul Brousse, Villejuif, France, said at the 2008 Gastrointestinal Cancers Symposium (abstract 283).
In colorectal liver mets, pCR heralds long-term survival
May 1st 2008ORLANDO-In a subset of patients with colorectal liver metastases, a pathologic complete response can be achieved with preoperative chemotherapy, rendering “uncommonly high” disease-free and overall survival rates, French investigators reported at the 2008 Gastrointestinal Cancers Symposium (abstract 333).
