PHILADELPHIA — The American Association for Cancer Research supports World Cancer Day on Saturday, Feb. 4, and the efforts of the Union for International Cancer Control (UICC) to bring the looming world cancer crisis to the forefront by urging the public, government leaders and health policy makers to take proactive steps in the global fight against cancer.

The 2012 World Cancer Day initiative, in following the footsteps of this year’s theme “Together it is Possible,” is raising public awareness through education and encouragement of healthy lifestyle choices in an effort to reduce cancer risk.

“World Cancer Day is a reminder that we must take action and work together to decrease the global burden of cancer,” said Margaret Foti, Ph.D., M.D. (h.c.), chief executive officer of the AACR. “The AACR has had a long-standing focus on cancer prevention research. We believe that known prevention strategies offer long-term potential for lowering cancer incidences and mortality and we urge everyone to take action.”

Worldwide, cancer cases are projected to almost double to 21.4 million by 2030, with nearly two-thirds of all diagnoses occurring in low- and middle-income countries. In the United States alone, approximately 1.64 million people will be diagnosed with cancer and more than 577,000 will die of the disease in 2012. However, one in three cancer deaths are preventable through lifestyle changes such as these:

• Eat a healthy diet full of fruits and vegetables, limit your fat intake and if you consume alcohol, do so in moderation.
• Exercise regularly, at least 30 minutes a day, and maintain a healthy weight.
• Avoid tobacco use – this includes cigarettes, pipes, water pipes and chewing tobacco.
• Protect yourself from the sun by avoiding midday sun, wearing sunscreen, and avoiding tanning beds and sunlamps.
• Get vaccinated and protect yourself from certain viral infections like the Hepatitis B virus and the human papillomavirus (HPV).
• Be aware of your family history, learn the signs of cancer, perform self-exams and get proper routine cancer screenings by your doctor.

How else can you help? Take action, join the fight against cancer and sign the World Cancer Day declaration. The declaration is an initiative to bring the global cancer burden to the attention of governments and health policy makers.

In an effort to rally the online community, a dedicated 2012 World Cancer Day application on Facebook has been launched to allow users to make their personal pledge by donating their Facebook status. A companion campaign on Twitter will support #WorldCancerDay as a trending topic. Express your commitment to cancer prevention publicly.

It is only by every person, organization and government entity doing their part that we will be able to reduce the global cancer burden. Learn more about World Cancer Day, and how you can get involved: http://www.worldcancerday.org/wcd-home.

• Findings suggest the effects of food may be more complex.
• Adverse effect observed in younger women.

PHILADELPHIA — Soy isoflavone supplements did not decrease breast cancer cell proliferation in a randomized clinical trial, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Lead researcher Seema A. Khan, M.D., professor of surgery at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, said the results of this study are consistent with the findings of previous studies that were designed to test cancer prevention benefits of dietary supplements.

“Simply put, supplements are not food. Although soy-based foods appear to have a protective effect, we are not seeing the same effect with supplementation using isolated components of soy, so the continued testing of soy supplements is likely not worthwhile,” said Khan.

Khan said that beta-carotene and selenium supplementation have also been shown to lack benefit in lung cancer prevention studies.

“Foods are very complex and there are likely traveling companions that we haven’t identified that are protecting against cancer,” said Khan.

For the current study, Khan and colleagues randomly assigned 98 women to receive a mixed soy isoflavones supplement or placebo. Isoflavones are components of soy foods that were expected to have anti-estrogen activity.

These women had more than 4,000 breast cancer epithelial cells identified by fine needle aspiration biopsy. At six months, researchers evaluated the levels of Ki-67, an established protein marker of cancer cell growth. In the overall population, no difference was seen after six months in either group. However, among pre-menopausal women, the level of Ki-67 increased from 1.71 to 2.18, suggesting a negative effect of the supplementation.

“This was a small finding, but one that should suggest caution,” said Khan.

• A20 E3 ubiquitin ligase could be a therapeutic target.
• Targeting this ligase may overcome TRAIL resistance.
• No current therapy available for glioblastoma.

PHILADELPHIA — Glioblastoma, a lethal brain cancer, is one of the most resistant to available therapies and patients typically live approximately 15 months.

Previous research has focused on the activation of the apoptosis, or cell death, pathway using therapeutic agents such as tumor necrosis factor-related apoptosis-inducing ligand (TRAIL); however, the vast majority of these experiments have been stymied by resistance.

“Scientists in this field have been hoping to treat this cancer with this new type of apoptosis pathway-targeted therapeutic drug, and this new information may provide a path forward,” said Chunhai “Charlie” Hao, M.D., Ph.D., a neuropathologist at Emory University.

Using human glioblastoma samples and tumor-initiating cells or cancer stem cells, Hao and colleagues identified a possible new pathway for targeted therapies. Results of their work are published in Cancer Discovery, the newest journal of the American Association for Cancer Research.

TRAIL treatment often leads to caspase-8-mediated apoptosis. However, study results showed that the A20 E3 ligase is highly expressed in glioblastomas and together with receptor interacting protein 1 (RIP1) and caspase-8, forms a signaling complex. Upon TRAIL interaction with this complex, the A20 E3 ligase triggers ubiquitination of RIP1, interferes with activation of caspase-8 and prevents caspase-8-initiated apoptosis.

“Previous research in this area has been unable to overcome the obstacle created by resistance. This research shows one of the mechanisms for how we can manipulate the ubiquitination process to overcome the resistance to the apoptosis-targeted cancer therapies,” said Hao.

Understanding the mechanisms of resistance is vital to developing therapies going forward, according to Hao.

• Changes to specific proteins can lead to tumor growth and development.
• Glioblastoma patients often have a poor prognosis.
• Understanding molecular mechanisms can lead to new treatments.

PHILADELPHIA — Most research on glioblastoma development, a complicated tumor of the brain with a poor prognosis, has focused on the gene transcription level, but scientists suggest that post-transcriptional regulation could be equally or even more important.

In a recent report in Molecular Cancer Research, a journal of the American Association for Cancer Research, scientists led by Luiz O. F. Penalva, Ph.D., an assistant professor in the department of cellular and structural biology at the University of Texas Health Science Center at San Antonio, illustrated that the connection between two RNA-binding proteins, Musashi1 and HuR, can have important consequences to glioblastoma.

“This is a novel finding in terms of what we know about glioblastoma development,” said Penalva. “Most of what we know about glioblastoma is limited to gene transcription-level research, but there are other regulatory processes beyond transcription that when disrupted could contribute to tumor formation.”

RNA-binding proteins are key regulators in all cellular processes from splicing to translation. Changes that affect either their function or expression levels can have dramatic consequences to protein production and can lead to disease states including cancer.

In the lab, Penalva and his colleagues showed that increased levels of HuR up-regulate the expression of another RNA-binding protein, Musashi1. Both proteins control the expression of cancer-related genes; their interaction brings together two important gene networks with major consequences to glioblastoma development.

The results are still early, but Penalva stressed that little is known about glioblastoma development and the findings represent a move toward greater understanding.

“To treat cancer, you have to understand what triggers tumor formation,” said Penalva. “If we continue to think that all the activity is at the transcription level, we are just fooling ourselves. Clearly, something is going on beyond that level.”

PHILADELPHIA — The American Association for Cancer Research has updated its embargo sanctions policy. This revised policy affects all meetings and journals promoted by the AACR.

In sum, the AACR supports quality scientific journalism and recognizes that comprehensive stories take time to prepare carefully. Toward that end, the AACR Communications Department often releases material early, under embargo, to credentialed journalists. This process requires trust and responsibility on the part of both parties. The revised embargo policy recognizes that journalists and other media professionals occasionally make honest mistakes; these mistakes should not permanently damage the relationship between the association and the media.

Therefore, each embargo break by a journalist or outlet will be investigated by the AACR Communications Department. If the break is determined to be accidental, the outlet will take internal steps to make sure its processes are corrected. After assurances are made, both verbally and in writing, that these steps have been taken, the AACR will maintain the press credentials of the media outlet.

However, repeat offenders may face sanctions at the discretion of the AACR Communications Department, which potentially include removal from AACR mailing lists, dismissal from AACR meetings and the possible removal of the ability to cover other AACR events.

Read the complete, revised AACR embargo policy.

• Smokers are more likely to have molecular features of cancerization in the large airway epithelium.
• Smokers with COPD had significant changes in the small airway epithelium.
• Findings could lead to development of a diagnostic test.

SAN DIEGO — Smoking may be associated with the development of molecular features of cancer in the large airway epithelium. In the small airway epithelium, molecular cancerization is associated with development of chronic obstructive pulmonary disease, according to recent data. 

“We are striving to find the earliest molecular changes that are induced by environmental stressors — in this case, smoking,” said Renat Shaykhiev, M.D., Ph.D., assistant professor of genetic medicine at Weill Cornell Medical College, who presented the findings at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer: Biology, Therapy and Personalized Medicine, held Jan. 8-11, 2012. “Our goal is to understand the early pathogenesis of lung cancer and to develop strategies to prevent lung cancer in susceptible individuals.”

Shaykhiev and colleagues analyzed the large and small airway epithelia of healthy nonsmokers, healthy smokers and smokers with chronic obstructive pulmonary disease (COPD), which is typically caused by long-term smoking, for expression of so-called “molecular cancerization” features (i.e., the genes upregulated in lung cancer compared with nonmalignant adjacent tissue).

Researchers found significantly more cancer-like gene expression changes in the large airway epithelia of smokers than in those of nonsmokers. When analyzing the small airway epithelium, though, they did not find significant differences between healthy smokers and nonsmokers, but they did find significant overall upregulation of cancerization genes in smokers with COPD. Analysis of these genes in the large and small airway epithelia obtained from the same individuals revealed that molecular cancerization occurs more frequently in the large airway epithelium than in the small airway epithelium.

Shaykhiev and colleagues drew the following conclusions: Smoking is associated with acquisition of molecular cancerization features in the large airway epithelium prior to the development of disease, and the large airway epithelium is likely more susceptible to smoking-induced changes than the small airway epithelium, implying that it may be the primary site of molecular alterations leading to lung cancer in smokers.

These findings could potentially lead to the development of a diagnostic test that would look for these genetic changes in susceptible individuals, the researchers suggested.
“Ideally, we would use these genes to do very routine analysis to determine which smokers or even nonsmokers are at risk for development of lung cancer,” said Shaykhiev.

• Novel Hsp90 inhibitor shows activity in slowing KRAS-mutant NSCLC tumor cell growth.
• Use with traditional chemotherapy resulted in increased cancer cell death.
• Phase 2b/3 trial combined with docetaxel under way.

SAN DIEGO — The investigational drug ganetespib, a synthetic second-generation Hsp90 inhibitor, slowed the growth of cancer cells taken from non-small cell lung cancer tumors with a mutation in the KRAS gene. The drug was even more active when combined with traditional lung cancer treatments and other investigational targeted therapies, according to preclinical study data.

David A. Proia, Ph.D., and Jaime Acquaviva, Ph.D., scientists at Synta Pharmaceuticals Corp., presented the data at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer: Biology, Therapy and Personalized Medicine, held Jan. 8-11, 2012.

Currently, patients with non-small cell lung cancer (NSCLC) with KRAS mutations have no effective treatment strategy. A phase 2 trial showed tumor shrinkage in more than 60 percent of patients with KRAS-mutant NSCLC at eight weeks after treatment with ganetespib administered once weekly as a monotherapy, indicating the drug’s potential effectiveness, according to Proia.

He and his colleagues examined whether ganetespib was effective against several different cell lines of KRAS-mutant NSCLC and confirmed it was effective in 15 different cell lines. They then sought to determine which combination treatments would enhance the activity of ganetespib in this cancer type.

First, the researchers combined ganetespib with several standard-of-care chemotherapies currently available in the clinic for KRAS-mutant NSCLC tumor samples. They found that the combination of ganetespib with alkylating agents, antimitotics and topoisomerase inhibitors resulted in an increased cell death of 1.4-, 1.5- and 2.6-fold, respectively, compared with ganetespib alone.

“We saw great activity with, for example, docetaxel and [ganetespib],” Proia said. “What we are doing now is conducting a large phase 2b/phase 3 trial with docetaxel and [ganetespib] in NSCLC patients. Activity in the KRAS-mutant subpopulation is a coprimary endpoint in this trial.”

The researchers also tested ganetespib in combination with two therapies that target pathways known to be involved in NSCLC: a MEK inhibitor or a PI3K/mTOR inhibitor. Results in tumor samples revealed that combining ganetespib with either therapy was also more active in slowing tumor growth compared with ganetespib alone.

“Not only was ganetespib activity enhanced in combination with traditional chemotherapies, which may be understood in terms of the ability of Hsp90 inhibition to block certain resistance or repair mechanisms, but activity was also enhanced in combination with a number of targeted therapies for which recent work has shown very interesting complementary inhibition of signaling pathways,” Proia said.

Finally, the researchers further validated their results by combining ganetespib with the PI3K/mTOR inhibitor in mice with KRAS-mutant NSCLC. Both drugs alone promoted tumor shrinkage, but the combination resulted in a greater inhibition of tumor growth.

If further validated, this research could open up avenues for future treatment options for patients with KRAS-mutant NSCLC.

• Survival rates were “unsatisfactory” in patients with NSCLC and a KRAS mutation.
• “Great need” exists for new treatment combinations in this patient population.

SAN DIEGO — Sorafenib was effective in patients with non-small cell lung cancer and a KRAS mutation, but survival rates were reportedly “unsatisfactory,” according to data presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer: Biology, Therapy and Personalized Medicine, held Jan. 8-11, 2012.

Patients with lung cancer and a KRAS mutation are believed to have a poor prognosis and may not benefit from treatment with epidermal growth factor receptor tyrosine kinase inhibitors, according to study author Wouter W. Mellema, M.D., a doctoral candidate at VU University Medical Center in Amsterdam.

“There is a great need for targeted treatment options for patients with non-small cell lung cancer (NSCLC) with a KRAS mutation,” he said.

In the phase 2, multicenter study conducted in the Netherlands, researchers assigned 57 patients with NSCLC and a KRAS mutation to 400 mg of sorafenib twice daily.

At six weeks, Mellema and colleagues reported a rate of no progression of 52.6 percent. Fifteen patients stopped treatment before six weeks — 10 of whom stopped due to clinical progression. Median progression-free survival was 2.3 months, and median overall survival was 5.3 months. The researchers reported that 14 patients are still alive.

“Sorafenib could be a useful drug in this patient population by inhibiting the growth-stimulating signal of the RAS protein,” Mellema said. “However, although sorafenib showed relevant activity, the outcome was unsatisfactory.”

Mellema and his team had conducted a pilot study in 10 patients, which showed “very promising results. Unfortunately, the results of the phase 2 study were less optimistic. We expected that progression-free survival and overall survival would be better [in the phase 2 study],” Mellema said.

He suggested that the KRAS mutation causes early progression by stimulating cell growth through an alternative pathway. “Future studies currently in preparation in our group should focus on simultaneous inhibition of these pathways,” he said.

• Certain genes can be used to define the lung tumor’s type and ability to clone.
• Genetic status information might be used to presume genetic background.

SAN DIEGO — Multicentric carcinogenesis with the same genetic mutation appears to occur in lung adenocarcinoma, according to data presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer: Biology, Therapy and Personalized Medicine, held Jan. 8-11, 2012.

Data also demonstrated that the EGFR and KRAS genes, which are mutually exclusive, can be used to define clinically relevant molecular subsets of lung adenocarcinoma and can define tumor clonality.

“The information on genetic status of multiple lung cancers is valuable and might be able to presume genetic backgrounds for carcinogenesis of the lung,” said Kenji Sugio, M.D., Ph.D., research director and chief of the department of thoracic oncology at the National Kyushu Cancer Center in Fukuoka, Japan.

By using high-resolution computerized tomography (CT), researchers are able to detect small-sized lung tumors and “sometimes multiple tumors.” Sugio and his colleagues analyzed the genotype of the EGFR and KRAS genes and the expression of the EML4-ALK fusion gene in synchronous multiple noninvasive adenocarcinomas to evaluate the possibility of multicentric carcinogenesis. According to Sugio, in five of the nine patients in this study, multiple tumors, which were defined as pathologically noninvasive tumors, showed the same genetic mutation.

“These findings demonstrate that multicentric carcinogenesis under the same genetic backgrounds occurs in lung adenocarcinoma,” Sugio said. “We expected a high incidence rate of the same genetic mutation in synchronous multiple lung adenocarcinomas because the whole lung of patients with lung cancer is thought to be under an almost uniform environment of carcinogen.”
