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.
The difficulty of finding the best way to find missing primary cancers
November 25th 2010Rosetta Genomics, which has a test to identify tissues of origin for metastatic cancers with an unknown primary, just won back the rights to market its own test in the US. But it's expected to post a loss this year. If it can find missing cancers, why isn't Rosetta rolling in cash?

Lung Cancer After 70: Is it a Different Disease?
November 15th 2010Despite the fact that elderly patients comprise over 50% of the non-small cell lung cancer (NSCLC) population, our knowledge regarding the efficacy and safety of chemotherapy in this group is suboptimal. The “elderly” (defined as individuals ≥70 years of age) experience physiologically normal aging of their bone marrow and kidneys, which inherently increases toxicity to therapy. Standard practice has often been to discourage the use of combination chemotherapy in these patients; however, general consensus guidelines emphasize that performance status should primarily guide the choice of treatment. Elderly patients with advanced NSCLC treated with platinum doublet therapy demonstrate similar efficacy (but increased toxicity) to their younger counterparts. Patients with metastatic disease in which a targeted and/or biological agent(s) was added to chemotherapy experienced benefits similar to those treated with standard platinum doublets, but with increased morbidity and mortality. In the future, effective testing of molecular targeted therapies will have to include elderly patients among research cohorts or risk excluding a large population of eligible patients. Overall, elderly patients with advanced NSCLC, while experiencing greater toxicity, demonstrate the same response rates and survival benefits as their younger peers.
Youth Has No Age: Cancer Treatment for Older Americans
November 15th 2010Calendar age and biological age do not always correspond. Pablo Picasso, source of the quote that begins the title of this commentary, lived a notoriously robust and active life through his later decades, dying in his nineties in the midst of a dinner party. In the oncology community, with the advent of targeted therapeutics and better supportive care, the disparity between the two is likely to be increasingly relevant to both research and practice. In this issue of ONCOLOGY, Chiappori et al review data supporting the idea that even in the context of standard cytotoxic chemotherapy, elderly patients with advanced NSCLC experience similar response rates and similar survival benefits to those seen in younger patients. They note that biases excluding elderly patients from clinical trials result in gaps in our knowledge of how to best treat older patients.
Lung Cancer in the Elderly: What’s Age Got to Do With It?
November 15th 2010The review by Dr. Chiappori and colleagues in this issue of ONCOLOGY addresses an important challenge relating to the optimal management of elderly patients with lung cancer. The authors provide an excellent overview of the data in patients with various stages of non-small cell lung cancer (NSCLC). They also highlight the limitations of the existing data in the management of elderly NSCLC patients.
Second-Guessing the FDA: CMS’s Expanding Regulatory Role
November 15th 2010Nothing gets biopharma policy watchers more worked up than the possibility that the Centers for Medicare & Medicaid Services (CMS) will second-guess FDA approval decisions. In reality, though, CMS often has no choice but to apply its own interpretation to issues that also fall under the FDA’s jurisdiction-and implementation of the health care reform is bringing more of those cases to the fore.
