Proton therapy report advises caution
October 29th 2009The 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.
Circulating tumor cells edge out imaging in breast mets
October 20th 2009Five 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.
NATCH trial finds no benefit for chemo Rx plus surgery
September 23rd 2009SAN FRANCISCO-Chemotherapy before surgery for early-stage, non-small-cell lung cancer led to moderately higher survival rates than surgery alone, but not enough to reach statistical significance, according to follow-up analysis of the European NATCH trial. However, the researchers did note that patients were more likely to finish the prescribed chemotherapy course when treatment was given preoperatively.
Women with metastatic breast cancer fight for a place in the ‘pink parade’
September 23rd 2009Thanks to the tireless efforts of the breast cancer community, October and breast cancer are tightly bound with the ubiquitous pink ribbon. But the awareness campaign places a heavy emphasis on prevention, detection, and early diagnosis. For women with metastatic breast cancer, there is a sense that the “pink parade” has intentionally passed them by even though an estimated 465,000 annual deaths from breast cancer worldwide occur because of metastatic disease.
Introduction of PSA testing leads to dramatic rise in cancer incidence
September 22nd 2009More than a million additional cases of prostate cancer have been diagnosed and treated for prostate cancer over the last 20 years because of PSA screening, especially in younger men, according to the results of a SEER database analysis. The authors of this latest strike against screening claimed that most of this excess incidence represents overdiagnosis.
RIBBON-1 results bolster bevacizumab as add-on to standard Rx for metastatic breast cancer
July 28th 2009ORLANDO-RIBBON-1 results demonstrate that bevacizumab (Avastin) can be added to nearly any standard chemotherapy regimen for metastatic breast cancer, although the jury is still out on how meaningful the additional treatment is for overall survival.
Less is more when it comes to serial CA125 testing in ovarian cancer
July 28th 2009ORLANDO-For the majority of women who undergo ovarian cancer treatment, disease relapse is a matter of when rather than if. These women could spend the rest of their lives undergoing regular CA125 serum marker testing. A recent study that compares the quality of life in early- and advanced-stage ovarian cancer survivors found that CA125 marker measurements for recurrence were, understandably, a source of anxiety for both groups.
Combination therapies throw up roadblocks to oncogenic signaling pathways
April 27th 2009Forget the theory of diminishing returns: If one is good, then two must be better. As a result, cancer researchers are turning their attention to combination therapies, particularly for blocking tumor signaling pathways.
David Alberts: Survival of the fittest
April 24th 2009Desert living presents many challenges: extreme weather, lack of water, unfriendly cacti, and lethal creatures. Adaptability plus a strong survival instinct are key. David S. Alberts, MD, has plenty of both. When he relocated to the University of Arizona, he’d just finished up five years at the University of California, San Francisco, pouring his efforts into leukemia and myeloma research.
MR spectroscopy separates brain tumor recurrence from radiation necrosis
April 24th 2009MR spectroscopy results can help determine if brain tumor patients with nonspecific lesions may bypass invasive biopsy for conservative management. A study by a multidisciplinary group in Ann Arbor, Mich., found that elevated levels of brain metabolites correlated with evidence of tumor recurrence. The researchers then developed a tumor recurrence model based on their data.
Novel research makes inroads in cell death pathways
April 21st 2009DENVER—Designer T cells that attack tumors with a vengeance could be the future of prostate cancer treatment. Although the results are very preliminary, the incorporation of designer T cells into prostate cancer treatment led to a significant reduction in PSA levels, according to researchers from Boston University School of Medicine in Providence, R.I.
Epidemiology comes into its own at centenary AACR meeting
April 20th 2009DENVER—In 1974, Joseph Fraumeni Jr., MD, MSc, served as a member of the AACR annual meeting program committee. “At the time, epidemiology did not have a prominent place on the program,” Dr. Fraumeni said during the grand opening session of the 2009 AACR meeting. “In fact, only one abstract related to epidemiology was submitted, and it was mine. Since it was assigned to me for review, I promptly accepted my presentation.”
Noteworthy lectures focus on cutting edge therapeutics
December 11th 2008Oncology NEWS International guest editor Dr. Andrew D. Seidman recommends SABCS 2008 lectures on modern molecular science, molecular profiling, and the American Association of Cancer Research distinguished lectureship in breast cancer research.
Radiology resident compiles staging database
December 2nd 2008CHICAGO-When Roland Talanow, MD, PhD, began his radiology residency, the topic of cancer staging proved to be particularly confounding. In an effort to educate himself and help others, Dr. Talanow has built a free, Web-based database that offers one-stop shopping on cancer staging, including comprehensive information on lymphoma, non-Hodgkin’s lymphoma, and HIV-related lymphoma. Dr. Talanow showcased his Web site, www.cancerstaging.info, at RSNA 2008 (abstract LLR03001-H).
PET/CT for prostate ca influences staging, treatment strategy
December 2nd 2008CHICAGO-Prostate-specific antigen measurements are considered a useful organ-specific marker, but they are not necessarily an adequate tumor marker. PET/CT in combination with PSA levels can play a significant role in detecting and staging prostate cancer, according to two presentations at RSNA 2008 (abstracts SSA18-02 and SSA18-09).
Dual-energy CT scanning captures subtle pancreatic masses
September 1st 2008LAS VEGAS-The increased speed and improved visualization of dual-energy CT helps pinpoint lesions at an earlier, more treatable stage. Faster and better visualization are the main reasons to use dual-energy CT for the assessment of pancreatic masses, according to a radiologist from the University of Munich.
Salvage RT boosts disease-free survival in prostate ca
August 1st 2008Treatment inside a 2-year window and a PSA doubling time of less than 6 months may be the key factors for optimizing salvage radiotherapy results for recurrent prostate cancer, according to investigators from the Brady Urological Institute at Johns Hopkins School of Medicine in Baltimore.
Evaluating lung cancer response to therapy: Thinking beyond RECIST
June 2nd 2008LAS VEGAS-CT multitasks in the lungs, serving as a tool for cancer screening, disease diagnosis, lesion characterization, and lung cancer treatment response. CT can be used more effectively to assess treatment response in lung cancer patients, but clinicians must look beyond current response parameters, Michael McNitt-Gray, PhD, said at the 2008 Stanford International Symposium on Multidetector-Row CT.
MRI can monitor the prostate for local progression after ultrasonic ablation
June 2nd 2008High-intensity focused ultrasonic (HIFU) ablation is used to manage localized prostate cancer after external beam radiation therapy. But post-treatment alterations to prostate zonal anatomy hamper the assessment of local tumor progression in order to make decisions about second-line treatment. An interdisciplinary group from South Korea tested two MRI techniques for predicting local tumor progression.
Breast IMRT reduces acute radiation-induced dermatitis
June 1st 2008Using intensity-modulated radiation therapy for breast cancer patients after lumpectomy can reduce the incidence of acute dermatitis, compared with traditional whole-breast radiotherapy, reported Jean-Philippe Pignol, MD, of Sunnybrook Health Sciences Centre, Toronto, and colleagues.
Young fashion designer translates cancer fears into fierce frocks
June 1st 2008In the fashion world, the word fabulous is tossed around like bolts of fabric at a blowout sale. In the cancer treatment world, fabulous is not a common interjection. And when fashion design student Hattie Saltonstall was confronted with the disease, she felt far from fabulous.
Trial targeting stem cells in advanced breast ca begins
June 1st 2008CHICAGO-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.”
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.
Zoledronic acid ups PFS in younger early-stage pts
June 1st 2008CHICAGO-Zoledronic acid (Zometa) and adjuvant endrocrine therapy lowered the risk of disease recurrence in premenopausal women with early-stage breast cancer, according to the results of a major European trial. The bisphosphonate is already used to prevent bone loss in women undergoing adjuvant endocrine therapy for breast cancer.
