Myth Busting: Does Real-World Experience Lead to Better Drug Choices?
December 15th 2010In the era of evidence-based medicine, clinical guidelines, and personalized medicine, one would think that convincing clinical trial data would influence clinical practice if disseminated in an appropriate manner. However, it has been estimated that only 50% of current medical practice is evidence-based, clearly demonstrating a compelling need to collect and analyze additional data to better inform practice. Current data are usually gathered from a variety of sources, including clinical trials, observational studies, and meta-analyses. Yet according to Jeff Forringer, CEO of IntrinsiQ, data from oncology practices provide real-world outcomes that give better insight into the efficacy of cancer therapeutics.
Caring for Cancer Patients in the Future: A Perfect Storm on the Horizon?
December 15th 2010This timely manuscript by Bunnell and Shulman highlights critical issues that challenge our ability to provide care to cancer patients in the next 20 years. Each of the concerns the authors identify has a momentum of its own. In combination, they have the makings of a perfect health care storm. The time to further address these matters is now.
Where Expert Opinion Meets Public Resistance
December 15th 2010There is concern and growing evidence that the supply of medical oncologists in the United States will be insufficient to meet the needs of future patients. With an aging population and increasing complexity of cancer therapies, it is clear there will be more patients and that they will live longer and require expert care. It is equally clear that the number of specialists trained in cancer medicine is not growing fast enough to meet projected needs, so new models of care will need to be designed and implemented. Innovation in practice models will require the integration of non-physician practitioners (nurse practitioners and physician assistants) into multidisciplinary teams, broader use of technology to allow virtual consultations and the secure exchange of vital health information, increased utilization of community services, and public acceptance.
Will We Be Able To Care For Cancer Patients In The Future?
December 15th 2010The number of cancer patients and cancer survivors continues to increase rapidly amid predictions of a shortfall in physicians to care for them. In addition, newer cancer therapies have become increasingly complex and resource-intensive, compounding the impending workforce shortage. Simultaneously, the growing understanding of the biologic heterogeneity of cancer and the development of pharmacogenomics have opened up the possibility of personalized approaches to cancer diagnosis and treatment. Such personalization has been promulgated as a means of decreasing the cost of drug development, improving the efficacy of treatments, and reducing treatment toxicity. Although there have been notable successes, the fulfillment of these promises has been inconsistent. Providing care for future cancer patients will require the development of innovative delivery models. Moreover, new approaches to clinical research design, to the assessment of therapeutic value, and to the approval of and reimbursement for diagnostics and treatments are needed.
Histology… For Want of Anything Better?
December 14th 2010Recent studies have shed new light on the role of histology in predicting sensitivity to therapeutic agents such as pemetrexed (Alimta) or bevacizumab (Avastin). Whereas during the past 30 years, the only useful histologic consideration was the absence or presence of a “non” before “small-cell lung cancer,” two US Food and Drug Administration (FDA)-approved drugs now have histologic restrictions. In this issue of ONCOLOGY, Selvaggi and Scagliotti provide an interesting review on how an old tool such as histology has recently emerged as a new criterion for treatment decisions in metastatic non–small-cell lung cancer (NSCLC). However, recent experience with tyrosine kinase inhibitors (TKIs) targeting the epidermal growth factor receptor (EGFR) demonstrate that we need to move beyond histology to improve outcomes for patients with advanced NSCLC.

Denosumab Continues to Dampen Skeletal-Related Side Effects in Breast Cancer Bone Metastases
December 13th 2010An update of a long-term denosumab (Xgeva) trial offers another bisphosphonate as an alternative to zoledronic acid (Zometa) that is more convenient, less toxic, and more effective in bone metastases. But oncologists need to perform an oral exam of patients with bone metastases before placing them on denosumab.
PET/MR challenges PET/CT as ‘go to’ modality in oncology
December 8th 2010A new hybrid technology emerged at radiology’s mega conference in Chicago earlier this month, one that may dislodge decade-old PET/CT from its prominent berth for the diagnosis and monitoring of cancer patients. This new modality combines the positron-imaging component of PET/CT with oncology’s premier anatomic modality, MR, opening the door to cancer images with unprecedented clarity and clinical value.
Oncologists seek refuge from stalled economy by joining forces
December 5th 2010More oncologists in the past few years have opted to consolidate with other practices in their area or sought employment at hospitals. Results from an ongoing survey highlights the ups and down of cancer care, with most professionals reporting they are happy with their chosen specialty.
From the ONI archives: Specialists contend with modest evidence on the value of adjuvant therapy
December 1st 2010ASCO recently released updated guidelines on the use of adjuvant endocrine therapy in hormone-receptor-positive breast cancer. While the guidelines focus on all postmenopausal women, those who are age 75 and older require special consideration. Unfortunately, meaningful data to help healthcare providers make treatment decisions for these patients are scarce, according to Peter Ravdin, MD, PhD, an executive committee member and scientific program planning member of SABCS 2010.
Cultural values sway public risk perception of HPV vaccine
November 30th 2010Despite being heralded as a major public health breakthrough, the HPV vaccine has seen its fair share of controversy. Most recently, 24 U.S. states tried to pass a bill to make the vaccine mandatory for school-age girls. But the bill did not make it past the introductory stages in all but one state for the reasons, both scientific and cultural, that have plagued the HPV vaccine from the start: The vaccine fails to protect against 30% of the strains of HPV that cause cervical cancer; there is not enough known about possible adverse events; vaccination may lull young women into a false sense of security, leading to risky sexual behavior.Legal researchers, led by Dan Kahan, JD, from Yale Law School in New Haven, Conn., conducted a study to assess the factors that influence the perceptions of the risks and benefits of the HPV vaccine among the general public. They surveyed 1,538 U.S. adults and found that two factors influenced how their respondents viewed the HPV vaccination: biased assimilation and cultural credibility. “Biased assimilation refers to the tendency of individuals selectively to credit and dismiss information in a manner that confirms their prior beliefs,” the authors explained. With regard to cultural credibility, “the results of this [study] suggest that polarization grows where culturally diverse subjects see the argument they are disposed to accept being made by the advocate whose values they share, and the argument they are predisposed to reject being made by the advocate whose values they repudiate”( Law Hum Behav online, January 14, 2010).Individuals who have cultural values that favor authority and individualism perceive the vaccine as risky while individuals with cultural values that favor gender equality and pro-community/government involvement in basic healthcare are more likely to see the vaccine as low risk and high benefit.The authors suggested that policymakers avoid creating the impression that a scientific debate trumps cultural standards, and consider cultural norms and biases.
Bevacizumab in Advanced Lung Cancer: In Search of the Right Drug for the Right Patient
November 30th 2010Bevacizumab has become a standard of care for first line therapy in a subgroup of advanced NSCLC patients. With the advent of other effective therapies in bevacizumab-eligible patients and the ongoing development and testing of biomarkers for cytotoxic agents, it remains to be seen whether continued use of bevacizumab will be justified in the absence of predictive biomarkers.
Unanswered Questions: Monoclonal Antibodies in the Treatment of Advanced Non–Small-Cell Lung Cancer
November 30th 2010Despite the fact that bevacizumab and cetuximab are both in an advanced stage of clinical development for use in treatment for unresectable NSCLC (with bevacizumab already licensed for the use in clinical practice), several unanswered questions regarding these drugs remain. A number of ongoing trials have been specifically addressed to answer them, however, the first priority should be to personalize treatment, through clinical or biological markers, in order to better select patients who could benefit from targeted therapy with decreased toxicity.
Handling incidental findings: the (less than) 1% solution
November 29th 2010Pathologies such as infections, or even tumors, crop up from time to time in patients examined for entirely unrelated issues. These "incidental findings"can put doctors-and patients-in a tight spot. How do they proceed with the patient, knowing that many of the asymptomatic signs of disease may never lead to clinical problems, or may simply be false positives?
UCLA renews grant to find countermeasures to dirty bombs
November 29th 2010Researchers in the radiation oncology department at UCLA’s Jonsson Comprehensive Cancer Center have received a $14 million grant to develop countermeasures that will help treat damage caused by radiological or nuclear threats such as a dirty bomb attack, with possible applications to radiotherapy-induced damage.
