Data published in the Journal of Clinical Oncology show that patients with advanced neuroendocrine tumors (NET) of the midgut who were treated with octreotide acetate (Sandostatin LAR Depot) experienced a 66% reduction in risk of disease progression vs placebo.
Sanofi-aventis US announced that the US Food and Drug Administration (FDA) has granted marketing approval for rasburicase (Elitek) to be used for the initial management of plasma uric acid (PUA) levels in adult patients with leukemia, lymphoma, and solid tumor malignancies who are receiving anticancer therapy expected to result in tumor lysis syndrome (TLS) and subsequent elevations of plasma uric acid.
Cancer killed a 14-year-old girl who died shortly after being given Cervarix as part of a national immunization program. Early reports speculated that there may have been a link between the shot and her death, but according to a coroner’s assessment, there was no indication that the culprit was the HPV vaccine, which is marketed by GlaxoSmithKline. The girl’s death was caused by malignant disease in the heart and lungs, according to the coroner’s report.
Obesity may contribute to chemotherapy resistance and increasing relapse rates among children with leukemia, an animal study in Cancer Research (online, September 22, 2009) suggests.
The incidence of pneumonia and invasive pulmonary aspergillosis in acute myeloid leukemia patients was reduced when they were given posaconazole (Noxafil) as prophylaxis.
A coalition of international cancer experts is warning that the global cancer burden will double over the next two decades with an increasing concentration of cases in low-income and middle-income countries.
Use of antidepressants, particularly selective serotonin reuptake inhibitors and possibly tricyclic antidepressants, is associated with a reduced risk of colorectal cancer, according to research by the Group Health Research Institute in Seattle. But it’s too soon to make specific recommendations on how to harness this potential value of these drugs in cancer prevention.
A new class of cancer alpha-pharmaceuticals is approaching the marketplace, one built around the basis of radiotherapy itself. An isotope of radium, the element discovered more than a century ago by Pierre and Marie Curie, is the cornerstone of this new class of radiopharmaceuticals.
The AACR has appointed George Prendergast, PhD, as the editor-in-chief of Cancer Research. He is the president and CEO of Lankenau Institute for Medical Research in Wynnewood, Penn., and previously served as a senior editor and deputy editor for the journal. Dr. Prendergast will take up the five-year editorship in January 2010
The limited evidence on the comparative effectiveness of proton-beam therapy, especially in comparison to other radiation-based treatment modalities, undermines the value of this up-and-coming technology, according to a comparative effectiveness report by the Agency for Healthcare Research and Quality.
Despite the widespread perception that dietary supplements are safe, few products have been subjected to rigorous research. The potential risks of dietary supplement use are not known. A powdered blend of fruits, vegetables, and grains, Juice Plus is aggressively promoted to cancer patients based on claims of antioxidant effects. Current research evidence indicates that the potential risks of antioxidants outweigh the benefits in the context of cancer treatment. Patients should discuss antioxidant supplementation with their physicians.
Repeat lumpectomy and retreatment radiotherapy following ipsilateral breast tumor recurrence (IBTR) by either external-beam irradiation or brachytherapy in lieu of salvage mastectomy is an area of significant recent clinical interest. Multiple authors have reported their results, with encouraging numbers of patients avoiding mastectomy.[1‑4]
Five may be the magic number to determine whether a patient can undergo therapeutic monitoring with a test for circulating tumor cells or must undergo an FDG-PET/CT exam, according to research out of M.D. Anderson Cancer Center.
Roche announced that enrollment in a phase III clinical trial testing bevacizumab (Avastin) plus chemotherapy for women with early-stage breast cancer was suspended after six patients who were given the drug developed congestive heart failure. Study protocols required that enrollment be stopped if six or more cases of congestive heart failure occurred in the first 200 patients, according to the company.
An analysis by researchers at the University of Michigan Comprehensive Cancer Center shows that costs vary widely for different treatment regimens and from one delivery method to another. Yet receiving more treatments and spending extra on more sophisticated technology may do little good, at least when it comes to pain relief.
Resistance to rituximab (Rituxan) has emerged as a considerable problem as the drug has become widely used to treat B-cell lymphomas, such as non-Hodgkin’s lymphoma, follicular lymphoma, and diffuse large B-cell lymphoma. A recent study in Blood suggested that resistance to rituximab is related to downregulation of CD20 expression via epigenetic mechanisms.
The first proton-beam therapy center in Loma Linda, Calif., opened almost 20 years ago, and today six are operating in the U.S. Another center will open by the end of 2009 with several more planned in the next two years, including centers in continental Europe and the UK. A growing body of research affirms the efficacy of proton-beam therapy (see Table).
Subtle clues to the better management of cancer patients may lie hidden in images otherwise used exclusively for diagnosis. German researchers at ECCO/ESMO 2009 have found that ultrasound images of lymph nodes may contain clues to whether and to what extent melanoma has begun to spread. The discovery raises the possibility that ultrasound might help oncologists predict a patient’s probable survival without the need for sentinel node biopsy (abstract O9303).
Stage II colon cancer patients who are negative for microsatellite instability and lymphocytic infiltrate should not undergo adjuvant chemotherapy, according to surgeons at Oregon Health and Science University and Legacy Health System, both in Portland.
Bayer has announced that Marijn Dekkers, PhD, will succeed Werner Wenning as CEO starting October 1, 2010.
Pathologists at the Yale University School of Medicine in New Haven, Conn., studied the relationship between the Oncotype Dx recurrence score and the cell cycle-related antigen Ki-67 in 32 breast carcinomas and evaluated for a potential association.
The comparison of brachytherapy and surgery may be done on several levels. This review focuses the comparison on toxicity, the “soft” endpoints of biochemical relapse-free survival and clinical relapse-free survival, and the “hard” endpoint of prostate cancer–specific mortality.
Standard treatment options for prostate cancer patients include surveillance, surgery, external-beam radiotherapy, brachytherapy, the combination of external-beam and brachytherapy, and the combination of radiotheraputic modalities with hormonal therapy, for appropriately chosen patients.
Question 1: Breast cancer remains among the most frequent diagnoses of cancer in women in the United States. Importantly research indicates that deaths due to breast cancer are decreasing, in part due to advances in treatment and earlier detection. Could you please comment about the advances in breast cancer imaging that have helped to facilitate earlier detection?Question 2: Could you briefly comment on the role of each of these modalities used in breast imaging?A. X-Ray mammography (digital and film screen)B. UltrasoundC. Molecular imagingD. Breast-specific gamma imagingQuestion 3: Could you please discuss indications for breast-specific gamma imaging and the clinical data to support these indications?Question 4: Are you able to cite an example as to how you used breast-specific gamma imaging in the clinic?Question 5: Could you please discuss the role of imaging in staging and treating breast cancer most appropriately? Is there new or novel technology that oncologists should be aware of when imaging is used for optimal visualization to assist in staging a woman diagnosed with breast cancer?Question 6: In your own clinical experience, what advances have you witnessed in breast imaging, particularly in regard to breast cancer, over the past 5 years?Question 7: Do you have any final comments you would like to make to our audience about advances or trends in breast imaging as it pertains to women with breast cancer?
There has been a growing recognition in recent years that young adults with cancer are a distinct demographic group with unique needs, issues, and challenges related to their age and developmental stage of life.
For young adult survivors, coming to terms with a life-threatening illness is a unique dilemma.
As oncology nurses, we increasingly encounter issues related to integrative medicine in our community practices, clinics, and hospitals.
Vitamin D-the so-called “sunshine vitamin”-is a fat-soluble substance and is classified more as a pro-hormone or steroid by some
