Phase III trial shows improved survival with TAS-102 in metastatic colorectal cancer refractory to standard therapies

The new combination agent TAS-102 is able to improve overall survival compared to placebo in patients whose metastatic colorectal cancer is refractory to standard therapies, researchers said at the ESMO 16th World Congress on Gastrointestinal Cancer in Barcelona. TAS-102 is a novel nucleoside anti-tumour agent consisting of trifluridine (FTD) and tipiracil hydrochloride (TPI). FTD is the active component of TAS-102 and is directly incorporated into cancer DNA, leading to DNA dysfunction. However, when FTD is taken orally it is largely degraded to an inactive form. TPI prevents the degradation of FTD. Read more here.

Phase III trial shows equivalent survival for cetuximab or bevacizumab with combination chemotherapy in metastatic colorectal cancer

For patients with KRAS wild-type untreated colorectal cancer, adding cetuximab or bevacizumab to combination chemotherapy offers equivalent survival, researchers said at the ESMO 16th World Congress on Gastrointestinal Cancer in Barcelona. The CALGB/SWOG 80405 trial studied patients whose tumours were KRAS wild-type at codons 12 and 13. Patients received mFOLFOX6 or FOLFIRI at the discretion of their doctor and were randomised to cetuximab (578 patients) or bevacizumab (559 patients). Read more here.

When is the cost of cancer 'toxic'?

June 20, 2014 (HealthDay News) -- A tool to assess "financial toxicity" for cancer patients -- namely, the expense, anxiety and stress of illness-related costs -- has been developed by University of Chicago Medical Center cancer specialists.

The team developed a brief questionnaire after discussions with 150 patients with advanced cancer, according to the study in the July issue of the journal Cancer.

Long-term use of aspirin may reduce risk for pancreatic cancer

Continual use of low-dose or regular-dose aspirin may cut a person’s risk of developing pancreatic cancer in half, a Yale School of Public Health and Yale Cancer Center study has found. Further, the degree of protection may grow the longer one takes the aspirin. The Yale researchers collected data from a Connecticut population study of 362 newly diagnosed pancreatic cancer patients and a control group of 690 disease-free people. They analyzed associations between risk of pancreatic cancer and past aspirin use. Read more here.

How a thick "sugar coating" on cells may drive aggressive cancers

A research team led by UC San Francisco scientists has shown that cancer-induced structural changes in a sugary coating ensheathing cells can promote mechanical interactions that fuel tumor growth and metastasis. According to Valerie Weaver, professor of surgery and anatomy, and director of UCSF’s Center for Bioengineering and Tissue Regeneration, the kinetic trap in the bulky glycocalyx of cancer cells could act as a sort of “all or none” switch: integrin binding and activation is generally less likely, but when it occurs it is decisive.

International phase III trial shows survival benefit of MM-398 added to standard treatment in post-gemcitabine metastatic pancreatic cancer

Adding the novel MM-398 to standard treatment for metastatic pancreatic cancer patients who have already received gemcitabine improves survival, researchers said at the ESMO 16th World Congress on Gastrointestinal Cancer in Barcelona. “Patients with metastatic pancreatic cancer or pancreatic cancer in general have very limited options,” said study author Andrea Wang-Gillam, assistant professor in the Division of Oncology at Washington University in St. Louis, USA. “These patients just simply don’t do well. This was a positive trial and will provide a new treatment option for patients with metastatic pancreatic cancer.” Read more here.

Summary Basis of Decision (SBD) for Bosulif

Health Canada has issued a Notice of Compliance under the Notice of Compliance with Conditions (NOC/c) Guidance to Pfizer Canada Inc. for the drug product, Bosulif. Based on Health Canada's review, the benefit/risk profile of Bosulif is favourable for the treatment of chronic, accelerated, or blast phase Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) in adult patients with resistance or intolerance to prior tyrosine-kinase inhibitor (TKI) therapy, and for whom subsequent treatment with imatinib, nilotinib and dasatinib is not clinically appropriate.

3-D scans could improve cancer detection

3-D mammograms may be better at finding cancer than regular scans, a large study suggests, although whether that means saving more lives isn’t known. The study involved almost half a million breast scans, with more than one-third of them using relatively new 3-D imaging along with conventional scans. The rest used regular mammograms alone. The 3-D scan combo detected one additional cancer per 1,000 scans, compared with conventional digital mammograms. Read more here.

Youth indoor tanning increases early risk of skin cancer

Dartmouth researchers have found that early exposure to the ultraviolet radiation lamps used for indoor tanning is related to an increased risk of developing basal cell carcinoma (BCC) at a young age. The researchers collected data on 657 participants in the New Hampshire Skin Cancer Study (all under 50) who had newly diagnosed cases of BCC and on 452 controls. The data they collected included the type of indoor tanning device used (sunlamps, tanning beds, or booths), and skin sensitivity to the sun and proportion of time spent outdoors in childhood. A higher proportion of patients with early-onset BCC reported indoor tanning with a tanning lamp compared to controls, and this association was present for all types of indoor tanning devices.

UAB study shows how brain tumor cells move and damage tissue, points to possible therapy

Researchers at the University of Alabama at Birmingham have shed new light on how cells called gliomas migrate in the brain and cause devastating tumors. The findings show that gliomas — malignant glial cells — disrupt normal neural connections and hijack control of blood vessels. The study provides insight into the mechanisms of how glioma cells spread throughout the brain as a devastating form of brain cancer, and potentially offers a tantalizing opportunity for therapy.

For cancer patients, new tool predicts financial pain

Along with the distress that comes with a cancer diagnosis and the discomforts of treatment, more patients now have to deal with "financial toxicity," the expense, anxiety and loss of confidence confronting those who face large, unpredictable costs, often compounded by decreased ability to work. In Cancer, a team of University of Chicago cancer specialists describe the first tool — 11 questions, assembled and refined from conversations with more than 150 patients with advanced cancer — to measure a patient's risk for, and ability to tolerate, financial stress. The researchers named their patient-reported outcome measure COST (COmprehensive Score for financial Toxicity). Read more here.

A new tool to confront lung cancer

Huntsman Cancer Institute investigators report that misregulation of two genes, sox2 and lkb1, drives squamous cell lung cancer in mice. The discovery uncovers new treatment strategies, and provides a clinically relevant mouse model in which to test them. “This is the most exciting thing we’ve done,” said senior author Trudy Oliver, Ph.D., an assistant professor of oncological sciences at the University of Utah and Huntsman Cancer Institute investigator. “Now that we have a model it unleashes so many questions we can ask to gain a better understanding of the disease.” Read more here.

Report calls for new approach to Ontario's breast and colon cancer care

Ontario needs to improve the way it cares for breast and colon cancer patients taking protective chemotherapy, nearly half of whom are making unplanned visits to overburdened emergency rooms, according to a new evaluation of cancer care in Canada’s most populous province. The Cancer System Quality Index, released Tuesday, shows that 46 per cent of colon cancer patients and 43 per cent of breast cancer patients who received chemotherapy after surgery turned to ERs at least once, an outcome that suggests oncologists and family doctors are not doing enough to help patients cope with the toxic side effects of their therapy.

Selumetinib in uveal melanoma

In patients with advanced uveal melanoma, treatment with the agent selumetinib, compared with chemotherapy, resulted in an improved cancer progression-free survival time and tumour response rate, but no improvement in overall survival, according to a study in JAMA. The modest improvement in clinical outcomes was accompanied by a high rate of adverse events. Read more here.

Gene expression profiling test expands to assess colon and prostate cancers

The high price of gene expression profiling – and the uneven coverage for it across this country – point to the hard choices ahead for provincial health departments as personalized cancer medicine moves from dream to day-to-day reality in oncologists’ offices and cancer clinics. Health officials always wrestle with what to pay for, but new assays that can tailor treatments for cancer, Canada’s number one killer, are upping the ante. Read more here.

Exercise may help chemotherapy side effects

Dr. Kristin Campbell, lead researcher of the exercise study and an assistant professor of physical therapy at the University of British Columbia, and colleagues recruited women treated for early-stage breast cancer in advance of a pilot study, presented in early June at the annual meeting of the American Society of Clinical Oncology in Chicago. At the end of the study, women in both the control and exercise groups showed little difference in their neuropsychological test results and self-reported cognitive functioning. However, the brain-imaging tests showed significantly increased activity in the exercise group in brain regions known to support task performance, attention and decision-making, Campbell said.

Scientists identify additional challenges in KRAS-driven cancers

Cancers driven by – and dependent on – the potent mutated cancer gene KRAS have an especially poor prognosis, and three decades of scientific attempts have failed to produce drugs that can attack KRAS and halt the tumors’ runaway growth. A renewed assault on the problem is underway, but researchers report they have identified a backup genetic pathway that can enable cancer cells to survive and thrive in the absence of KRAS. If and when it becomes possible to shut down the oncogene in human cancers, the findings suggest, this escape mechanism will have to be blocked as well to kill the tumor cells. Read more here.

UCLA scientists discover how adult stem cell regulation contributes to lung cancer

UCLA researchers led by Dr. Brigitte Gomperts, member of UCLA's Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research, have discovered how factors that regulate growth of adult stem cells that regenerate tissue for repair in the lungs can lead to the formation of pre-cancerous lesions. This process is thought to be the first stage in the development of lung cancer. Read more here.

Study finds stronger nicotine dependency associated with higher risk of lung cancer

People who are highly addicted to nicotine -- those who smoke their first cigarette within five minutes after awakening -- are at higher risk of developing lung cancer than those who wait for an hour or more to smoke. Researchers at NCI found this simple measure of nicotine dependency improved lung cancer risk prediction beyond standard smoking measures, such as cigarettes per day, age, gender, history of chronic obstructive pulmonary disease and other lung cancer risk factors.

The national dialogue focused on three main issues: advance care directives, palliative care, and euthanasia and physician-assisted dying. The main aim of the consultation process was to seek input from Canadians on their perceptions and views about the status of end-of-life care in Canada. Read the full report here.

Ontario’s High Risk Breast Screening Program is showing positive results

The Journal of Clinical Oncology has published a study on the Ontario Breast Screening Program (OBSP) High Risk Screening Program. The study evaluated the first year of the program, which launched in 2011 as an expansion of the OBSP. The results of the study show that the program is working as planned and is helping detect breast cancer in women who are considered to be at high risk for developing the disease. Read more here.

Lung-MAP launches: first precision medicine trial from National Clinical Trials Network

Lung-MAP is a multi-drug, multi-arm, biomarker-driven clinical trial for patients with advanced squamous cell lung cancer. Squamous cell carcinoma represents about a quarter of all lung cancer diagnoses, but there are currently few treatment options beyond surgery for the disease. The trial will use genomic profiling to match patients to one of several different investigational treatments that are designed to target the genomic alterations found to be driving the growth of their cancer. This innovative approach to clinical testing should both improve access to promising drugs for patients and ease the significant recruitment and infrastructure burdens on researchers involved in traditional clinical trials.

Medical research safeguarded in Europe

The European Society for Medical Oncology has welcomed the adoption of the Clinical Trials Regulation by the Council of the European Union and the European Parliament, which enters into force this week. The new clinical trial framework acknowledges the importance of using data stored for a clinical trial beyond the end of the study itself, for research purposes. Practically speaking, the Regulation states that when a patient gives his/her consent for a clinical trial, he/she can easily give a one-time consent for data to be used beyond the trial, for the purpose of medical research, still with the possibility to withdraw it at any time.

Tamoxifen-resistant breast cancer reversed when drug paired with anti-malaria agent

The inexpensive anti-malarial drug hydroxychloroquine (HCQ) reverses resistance to tamoxifen, a widely used breast cancer drug, in mice. Investigators from Georgetown Lombardi Comprehensive Cancer Center say adding HCQ to tamoxifen could provide a new treatment option for some women with advanced, postmenopausal estrogen receptor-positive (ER+) breast cancer. The ER+ subtype accounts for an estimated 70 percent of all breast cancers. While many of these women are treated with tamoxifen, which blocks estrogen from fueling the tumor, 50 percent of these cancers will either not respond or will become resistant to tamoxifen over time.

Broad Institute, MGH researchers chart cellular complexity of brain tumors

Cellular makeup of glioblastoma more diverse than previously thought

Scientists from the Broad Institute and Massachusetts General Hospital (MGH) have conducted a first-of-its-kind study that characterizes the cellular diversity within glioblastoma tumors from patients. The study, which looked at the expression of thousands of genes in individual cells from patient tumors, revealed that the cellular makeup of each tumor is more heterogeneous than previously suspected. The findings, which appear online in Science Express, will help guide future investigations into potential treatments for this devastating disease. Read more here.

Childhood cancer survivors hospitalized frequently years after cancer treatment

Survivors of childhood cancers were hospitalized more often and for longer durations because of blood disorders and other problems, many years after cancer treatment was completed, compared with the general population, according to a recent study. "Our findings demonstrate that childhood cancer survivors face ongoing problems that can lead to hospitalization, even for those who are decades past their original cancer diagnosis. This can negatively impact their quality of life," said Anne C. Kirchhoff, PhD, MPH, assistant professor of pediatrics at the Huntsman Cancer Institute of the University of Utah in Salt Lake City.

Lifetime cancer risk from heart imaging low for most children, but rises with more complex tests

Children with heart disease are exposed to low levels of radiation during X-rays, which do not significantly raise their lifetime cancer risk. However, children who undergo repeated complex imaging tests that deliver higher doses of radiation may have a slightly increased lifetime risk of cancer, according to researchers at Duke Medicine. The findings, published in Circulation, represent the largest study of cumulative radiation doses in children with heart disease and associated predictions of lifetime cancer risk. Read more here.

Longer telomeres linked to risk of brain cancer

ESMO survey sheds light on common clinical practice for incompletely resected lung cancer

A landmark survey of more than 700 specialists provides crucial real-world insight into the treatments most oncologists choose for lung cancer patients whose tumour has been incompletely resected, an expert from the European Society for Medical Oncology (ESMO) says. Researchers led by Raffaele Califano of The Christie NHS Foundation Trust, Manchester, UK, surveyed 768 oncologists from 41 European countries about the treatments they offered patients who had “R1 resected” non-small-cell lung cancer. Of the respondents, 91.4% prescribed chemotherapy, mostly cisplatin/vinorelbine or cisplatin/gemcitabine. Read more here.

Phase III study strengthens support of Ibrutinib as second-line therapy for CLL and SLL

Topic: Haematologic malignancies / Anticancer agents & Biologic therapy

In a head-to-head comparison of two drugs for the treatment of relapsed chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), ibrutinib statistically significantly outperformed ofatumumab as a second-line therapy, according to a multicentre interim study published in the OnLine First edition of the New England Journal of Medicine on 31 May 2014.

Ibrutinib is the first drug designed to target Bruton's tyrosine kinase (BTK), a protein essential for CLL-cell survival and proliferation. In patients with CLL or SLL, a short duration of response to therapy or adverse cytogenetic abnormalities are associated with a poor outcome.

Nutrition and physical activity to prevent ovarian cancer: examining the evidence

To keep evidence current and updated into the future, WCRF (World Cancer Research Fund)/AICR (American Institute for Cancer Research) is undertaking the Continuous Update Project (CUP), in collaboration with Imperial College London. The project is an on-going review of food, nutrition, physical activity, body fatness, and cancer research.

In this updated report on the prevention of ovarian cancer, the CUP Panel concluded: 1. The evidence that developmental factors leading to greater linear growth (marked by adult attained height) are a cause of ovarian cancer is convincing; 2. Greater body fatness (which the Panel interprets to be marked by body mass index (BMI)) is probably a cause of ovarian cancer; 3. The evidence suggesting that lactation protects against ovarian cancer is limited.

Women with metastatic breast cancer could safely receive bisphosphonates less frequently

Women with metastatic breast cancer to the bone may receive bisphosphonates less often after the first year of monthly administration. With that change in practice, patients with breast cancer and bone metastasis may also reduce their risk of serious side effects, according to a study led by researchers at The University of Texas MD Anderson Cancer Center. The research was presented at the American Society of Clinical Oncology (ASCO) 2014 Annual Meeting (30 May-3 June, Chicago, USA) by Prof. Gabriel Hortobagyi. Read more here.

New test predicts if breast cancer will spread

A test that counts the number of locations in tumor specimens where tumor cells may invade blood vessels predicted the risk of distant spread, or metastasis, for the most common type of breast cancer. "Tests assessing metastatic risk can help doctors identify which patients should receive aggressive therapy and which patients should be spared," said Thomas Rohan, M.D., Ph.D., the lead and corresponding author of the study and professor and chair of epidemiology & population health at Einstein and Montefiore.

New treatment option for young women with hormone-sensitive breast cancer

A drug used for treating breast cancer, known as exemestane, is more effective than a common breast cancer prevention drug, tamoxifen, in preventing breast cancer recurrence in young women who also receive post-surgical treatment to suppress ovarian function. The findings from this trial were in women who had a form of early breast cancer that was sensitive to hormonal treatment. The combined results of the TEXT (Tamoxifen and Exemestane Trial) and SOFT (Suppression of Ovarian Function Trial) were presented at the 2014 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago (late breaking abstract #1) and published online in the New England Journal of Medicine.

Clinical trial analysis suggests drug combination may be highly effective in recurrent ovarian cancer

Significant improvement with the use of a combination drug therapy for recurrent ovarian cancer was reported at the annual meeting of the American Society of Clinical Oncology (ASCO) meeting in Chicago (late breaking abstract #5500). This is the first ovarian cancer study to use a combination of drugs that could be taken orally. The drugs were tested in a phase I combination study followed by a randomized phase 2 trial sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health.

Treatment helps young women preserve their fertility during breast cancer chemotherapy

Researchers have found that young women with breast cancer were able to better preserve their fertility during cancer treatments by using hormone-blocking drug injections that put them into temporary menopause. The results announced at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago are from the Prevention of Early Menopause Study (POEMS), a clinical trial sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health (ASCO late breaking abstract #505). Women receiving the injections were only about one-third as likely to experience ovarian failure, a common long-term toxicity of chemotherapy treatments, and were more than twice as likely to have a normal pregnancy after their cancer treatment compared to women in the trial who did not receive the injections.

Scientists discover potential new target for cancer immunotherapy

Scientists have found a way to target elusive cells that suppress immune response, depleting them with peptides that spare other important cells and shrink tumors in preclinical experiments. “We’ve known about these cells blocking immune response for a decade, but haven’t been able to shut them down for lack of an identified target,” said the paper’s senior author, Larry Kwak, M.D., Ph.D., chair of Lymphoma/Myeloma and director of the Center for Cancer Immunology Research at The University of Texas MD Anderson Cancer Center.

Gene mutation found for aggressive form of pancreatic cancer

Researchers at the University of California, San Diego School of Medicine have identified a mutated gene common to adenosquamous carcinoma (ASC) tumors – the first known unique molecular signature for this rare, but particularly virulent, form of pancreatic cancer. They report that ASC pancreatic tumors have somatic or non-heritable mutations in the UPF1 gene, which is involved in a highly conserved RNA degradation pathway called nonsense-mediated RNA decay or NMD.

Discovery could pave way to new treatment for rare jaw tumor

Researchers at the Stanford University School of Medicine have identified the mutations underlying a rare, understudied type of jaw tumor called ameloblastoma. In a paper published online May 25 in Nature Genetics, the researchers identify mutations in two genes that are associated with 80 percent of ameloblastoma cases. Read more here.

Expanded health coverage may improve cancer outcomes in young adults, study suggests

Young adults who lack health care insurance are more likely to be diagnosed in advanced stages of cancer and have a higher risk of death, according to a study from Dana-Farber/Brigham and Women’s Cancer Center (DF/BWCC) and Harvard Medical School. “We found that patients who have insurance coverage do better on every measure,” said first author Ayal Aizer, MD, MHS, of the Harvard Radiation Oncology Program.

DREAM project crowdsources answer to cancer cell drug sensitivities

A study published June 1 in the journal Nature Biotechnology describes the results of an open challenge to predict which breast cancer cell lines will respond to which drugs, based only on the sum of cells’ genomic data. The winning entry, from the Helsinki Institute for Information Technology, was 78 percent accurate in identifying sensitive versus resistant cell lines, and was one of 44 algorithms submitted by groups from around the world.

European Medicines Agency adopted a change to an indication for eribulin

The European Medicines Agency Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending a variation to the terms of the marketing authorisation for the medicinal product eribulin (Halaven). Halaven is indicated for the treatment of patients with locally advanced or metastatic breast cancer who have progressed after at least one chemotherapeutic regimen for advanced disease.

Duke researchers identify new brain cancer mutation that will aid drug development

A collaborative effort between Duke Medicine researchers and neurosurgeons and scientists in China has produced new genetic insights into a rare and deadly form of childhood and young adult brain cancer called brainstemglioma. The researchers identified a genetic mutation in the tumor cells that plays a role in both the growth and the death of a cell. Additionally, the mutation to the newly identified gene may also contribute to the tumor’s resistance to radiation.

Tamoxifen for 10 Years an option: ASCO Guideline Update

Women with stage I to III hormone receptor–positive breast cancer should consider taking tamoxifen for 10 years, the American Society of Clinical Oncology (ASCO) says in a clinical practice guideline focused update.

The guideline, Adjuvant Endocrine Therapy for Women with Hormone Receptor–Positive Breast Cancer: American Society of Clinical Oncology Clinical Practice Guideline Focused Update, was published online in the Journal of Clinical Oncology on May 27. It replaces ASCO's 2010 guideline update.

Breath test may spot lung cancer

A new breathalyzer has been developed to both detect and assess various stages of lung cancer, providing an accurate detection in four out of five cases. According to study author Dr. Nir Peled, an oncologist at the Davidoff Cancer Center in Israel, "cancer cells not only have a different and unique smell or signature, you can even discriminate between subtypes and determine disease burden." The breathalyzer can be plugged directly into a computer's USB port, and could prove to be a low-cost first step to weed out people who definitely do not have lung cancer, lowering the cost of lung cancer screening.

New report estimates nearly 19 million cancer survivors in the U.S. by 2024

The number of cancer survivors in the United States, currently estimated to be 14.5 million, will grow to almost 19 million by 2024, according to an updated report by the American Cancer Society. The second edition of Cancer Treatment & Survivorship Facts & Figures, 2014-2015 and an accompanying journal article published in CA: A Cancer Journal for Clinicians find that even though cancer incidence rates have been decreasing for ten years, the number of cancer survivors is growing. This is the result of increases in cancer diagnoses driven by the aging and growth of the population, as well as the fact that people are living longer with cancer because of earlier cancer detection and more effective treatments.
