The preliminary findings were reported here at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer. The phase III, randomized, controlled trial included women with platinum-sensitive recurrent ovarian cancer…
“This is cutting edge medicine for ovarian cancer,” said Jonathan Oh, MD, a gynecologic oncologist at Texas Oncology, P.A., in Dallas. Dr. Oh presented the results of a preliminary study on the vaccine at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancer on March 28 in Chicago…
“The FDA approval has expanded treatments options for many metastatic breast cancer patients, but these new results are showing how effective the drug can also be for breast cancer patients who have already tried endocrine therapies and may be running out of options,” said lead investigator Angela DeMichele, MD, MSCE, associate professor in the division of Hematology/Oncology and Epidemiology and co-leader of the Breast Cancer Research Program at the Abramson Cancer Center. “Combined with the promising results from other trials looking at the effectiveness of this drug, our results indicate that palbociclib can extend the duration of disease control and produce tumor shrinkage in patients with estrogen-receptor positive (ER+) breast cancer, without the debilitating side effects of chemotherapy.” The newly-published phase II trial primarily sought to evaluate disease response and control, while monitoring for the presence of side effects such as neutropenia, an abnormally low white blood cell count. Patients enrolled in the trial had previously undergone several prior chemotherapy and hormonal regimens for metastatic disease…
In a study recently published in the journal Neuro-Oncology, a team of scientists led by Luni Emdad, M.B.B.S., Ph.D., and Paul B. Fisher, M.Ph., Ph.D., provided the first evidence of an important link between a specific microRNA, miR-184, and a cancer promoting gene, SND1, in the regulation of malignant glioma. miR-184 is known to suppress tumor development by regulating a variety of genes involved in cancer growth, while SND1 has been shown to play a significant role in the development of breast, colon, prostate and liver cancers. Through a variety of preclinical experiments, the team demonstrated that increasing the expression of miR-184 slows the growth and invasive characteristics of glioma cells through direct regulation of SND1. …
“Hypofractionated radiation is infrequently used for women with early-stage breast cancer, even though it’s high-quality, patient-centric cancer care at lower cost,” said lead author Bekelman, an assistant professor of Radiation Oncology, Medical Ethics and Health Policy at the University of Pennsylvania’s Perelman School of Medicine and Abramson Cancer Center. “It is clinically equivalent to longer duration radiation in curing breast cancer, has similar side effects, is more convenient for patients, and allows patients to return to work or home sooner.” Shown to reduce local recurrence and improve overall survival after breast conserving surgery, conventional whole breast radiation, given daily over five to seven weeks, has been the mainstay of treatment in the U.S. …
Published in the Journal of Clinical Oncology with an accompanying editorial, the study compared survival and other outcomes in 470 patients treated with radiation therapy at 101 treatment centers through a clinical trial held from 2002 to 2005. The trial was sponsored by the National Cancer Institute and organized by the Radiation Therapy Oncology Group (RTOG). The findings indicated that patients treated at the less-experienced centers were more likely to have cancer recurrence (62 percent versus 42 percent at five years) and had poorer overall survival compared with those at the highly-experienced centers (51 percent versus 69 percent five-year survival, respectively)…
The study suggests that doctors and patients may find it difficult to withhold treatment previously considered standard of care, even in the setting of high quality data demonstrating that the advantages are small. “The onus is on physicians to critically analyze data to shape our treatment recommendations for patients, weighing the potential toxicities of treatment against clinical benefit,” said Rachel Blitzblau, M.D., Ph.D., the Butler Harris Assistant Professor of Radiation Oncology at Duke University Medical Center. Blitzblau was the senior author of a study published online Dec. 8, 2014, in the journal Cancer. …
“The genetic signature we have found will be invaluable to understanding the biological mechanisms that drive therapeutic responses to immunotherapy for metastatic melanoma,” says Jedd Wolchok, MD, PhD, director of the Ludwig Collaborative Laboratory and associate director of the Ludwig Center for Cancer Immunotherapy at MSK, who co-led the study with Timothy Chan, MD, PhD, of MSK’s Human Oncology and Pathogenesis Program. “Further, our strategy can now be applied to determine the genetic signatures associated with the efficacy of a number of other immunotherapies and cancers.” Few approaches to treating cancer have generated as much excitement as immunotherapy, in which the immune system is engaged to destroy malignancies. One class of such treatments targets CTLA-4, a molecule expressed on the surface of killer T cells that ordinarily blocks their proliferation…
The findings are published online in Lancet Oncology. Study co-leads Dr. Robert Bristow, a clinician-scientist at Princess Margaret Cancer Centre, and Dr. Paul Boutros, an investigator at the Ontario Institute for Cancer Research, report that the gene test provides a much-needed quick and accurate tool to determine with greater precision the men who will do well with local treatment only (surgery or radiation), and those who will need extra treatment (chemotherapy and hormone therapy) to ensure the cancer is completely eradicated. …
“Ixazomib is an investigational, oral proteasome inhibitor with promising anti-myeloma effects and low rates of peripheral neuropathy,” says Shaji Kumar, M.D., a hematologist at Mayo Clinic and lead author of the study. “While it is well known that a combination of bortezomib, lenalidomide and dexamethasone is highly effective in treating newly diagnosed multiple myeloma, we wanted to study the safety, tolerability and activity of ixazomib in combination with lenalidomide and dexamethasone in newly diagnosed multiple myeloma.” Dr. Kumar and colleagues enrolled 65 patients (15 to phase 1 and 50 to phase 2) between November 2010 and February 2012. …
