Cancer Leadership Council statement: Reform Medicare payment for patient-focused care

NCCS joined its colleagues in the Cancer Leadership Council in publishing a statement of principles to guide reform of Medicare payment for cancer care. Major news outlets have suggested that Medicare beneficiaries are not receiving their cancer care due to the 2% cuts in Medicare payments required under the sequestration. NCCS and other cancer advocates have pledged to monitor the impact of sequestration on cancer patients. While sequestration is a concern, major reform of Medicare payment for cancer care is needed, and the CLC identified principles that would ensure a more patient-focused system of care.

Our feel-good war on breast cancer

"The idea that there could be one solution to breast cancer — screening, early detection, some universal cure — is certainly appealing. All of us — those who fear the disease, those who live with it, our friends and families, the corporations who swathe themselves in pink — wish it were true. Wearing a bracelet, sporting a ribbon, running a race or buying a pink blender expresses our hopes, and that feels good, even virtuous. But making a difference is more complicated than that."

Ginkgo studied for chemotherapy cognitive side effects

In the current study, researchers evaluated the possible benefits of ginkgo on protecting against cognitive impairment in those receiving chemotherapy. The results suggested that there was a lack of significant differences between the ginkgo group and the placebo group in terms of cognitive function. The placebo group reported worse nausea after chemotherapy. The researchers concluded that these findings lack support for the use of ginkgo in preventing cognitive impairment caused by chemotherapy. Further study is needed to determine whether ginkgo may be effective for this purpose. Read more here.

Province unveils new plan in cancer battle

As the number of cancer cases in Alberta continues to rise, the province has announced a new strategy, Changing Our Future: Alberta’s Cancer Plan to 2030, for cancer prevention, curing cancer, and reducing the suffering of cancer patients. “Every day, 42 Albertans learn they have cancer. We expect that to grow to 73 new cancer cases a day by 2030. We aim to change that,” said Health Minister Fred Horne. “Even though we have exceptional cancer care, we need to do more starting today. To wait means losing the opportunity to get ahead of the curve and that will end up costing much more in lives and in dollars.” Read more here.

Adequate supply level has been restored in all EU Member States and pegylated doxorubicin hydrochloride can now be used again without restrictions

The European Medicines Agency has announced that it has updated its recommendations on the use of Caelyx which were issued in the last two years. These recommendations followed a shortage of the medicine due to shortcomings in quality assurance identified at the manufacturing site, Ben Venue Laboratories. The Agency’s Committee for Medicinal Products for Human Use now considers that adequate supply levels have been restored in all EU Member States and that Caelyx can now be used again without restrictions as per its licensed indications. There is no longer a need to prioritise existing patients and new patients for whom no alternative treatment is available. Read more here.

Are the elderly excluded from practice-changing trials in advanced NSCLC?

The median age of patients diagnosed with advanced non–small cell lung cancer (NSCLC) has steadily increased in recent years, and is presently 70 years. Despite this, the elderly are significantly underrepresented in clinical trials. A study published in the Journal of Thoracic Oncology investigated the degree to which exclusion or underrepresentation of the elderly occurs in practice-changing clinical trials in advanced NSCLC. Researchers conclude that greater representation of elderly patients in phase III trials is required to better define evidence-based paradigms in the increasingly elderly NSCLC population.

UNC researchers engineer 'protein switch' to dissect role of cancer’s key players

Researchers at the University of North Carolina at Chapel Hill School of Medicine have “rationally rewired” some of the cell’s smallest components to create proteins that can be switched on or off by command. These “protein switches” can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease. In the first application of this approach, the UNC researchers showed how a protein called Src kinase influences the way cells extend and move, a previously unknown role that is consistent with the protein’s ties to tumor progression and metastasis.

Certain breast cancer patients may benefit from combined HER-2 targeted treatment without chemotherapy

In a report that appears in the Journal of Clinical Oncology, researchers have shown that a subset of breast cancer patients who have tumors overexpressing a protein called the human epidermal growth factor receptor 2 (HER-2 positive) may benefit from a combination of targeted treatments that zero in on the breast cancer cells themselves. That could enable some women to avoid the "sledgehammer" of typical chemotherapy drugs that kill normal and tumor cells alike and avoid triggering resistance in tumor cells. Read more here.

A tumor suppressor is identified as an inhibitor of inflammatory pathways

Scientists at the National Cancer Institute have found that a protein, FBXW7, which acts as a tumor suppressor, is also important for the reduction in strength of inflammatory pathways. This study is the first to describe how FBXW7 acts in cancer cells as well as in cells of the immune system to attenuate inflammatory signaling, which is accomplished by reducing the levels of C/EBPdelta, a protein that regulates the expression of many genes. Read more here.

Relationship between tumour biomarkers and efficacy in EMILIA trial identified women most likely to benefit from T-DM1

Patients in all biomarker subgroups in the EMILIA study had longer progression-free survival and overall survival with T-DM1 vs lapatinib plus capecitabine. In a biomarker subanalysis, patients with tumours expressing high HER2 mRNA levels derived even greater overall survival benefit from T-DM1. Lapatinib plus capecitabine-treated patients with PIK3CA mutations had worse outcomes than those with wild type PIK3CA. T-DM1-treated patients with PIK3CA mutations had a similar treatment benefit as those without, suggesting that the unique mechanism of action of T-DM1 may overcome PIK3CA mutation resistance. The findings were presented by Dr José Baselga, physician-in-chief at Memorial Sloan-Kettering Cancer Centre in New York, USA, at the AACR Annual Meeting 2013, held in Washington, D.C., April 6-10.

Cancer immunotherapy in children: How does it differ from approaches in adults?

More often than not, cancer immunotherapies that work in adults are used in modified ways in children. Seldom are new therapies developed just for children, primarily because of the small number of pediatric patients relative to the adult cancer patient population. In 2013 there will be an estimated 11,630 cases of cancer diagnosed in children 14 and younger compared to over 1.6 million cases diagnosed in adults. Read more here.

Experimental vaccine for ovarian cancer

Researchers at the Ovarian Cancer Research Centre in the University of Pennsylvania's Perelman School of Medicine have unveiled a new vaccine for treating ovarian cancer.  Although rare (it is believed that only 1.38% of females will be afflicted), ovarian cancer is usually not diagnosed until stage 3 or 4.  Lana Kandalaft, lead author in this study explains that this new treatment uses a personalized vaccine to instruct a patient's immune system to fight the tumor.  "Each patient's tumor is unique like a fingerprint...we're trying to rewire the immune system to target the tumor."

Researchers study effectiveness of intermittent therapy for prostate cancer treatment

Based on previous smaller studies, it looked like an approach called intermittent androgen deprivation therapy might be just as good as continuous androgen deprivation in terms of survival while meanwhile giving patients a breather from the side effects of therapy. But this new study, which treated 1,535 patients with metastatic prostate cancer and followed them for a median of 10 years, finds that's not the case. Read more here.

Newly identified tumor suppressor provides therapeutic target for prostate cancer

Working in close collaboration, the labs of Maria T. Diaz-Meco, Ph.D., and Jorge Moscat, Ph.D., found that PKCζ controls the activation of a pro-tumor gene called c-Myc. Normally, PKCζ’s alteration keeps c-Myc in check. But PKCζ levels are low in prostate and other cancers, leaving c-Myc free to enhance cell growth and metastasis. This study, appearing in the Proceedings of the National Academy of Sciences, suggests that restoring PKCζ could provide a new approach to treating prostate cancer. Read more here.

Time article describes team approach to cancer research

In a recent edition of Time magazine, Bill Saporito describes a team approach to cancer research. "The hero scientist who defeats cancer will likely never exist. No exalted individual, no victory celebration, no Marie Curie or Jonas Salk, who in 1955, after he created the first polio vaccine, was asked, So what’s next? Cancer? — as if a doctor finished with one disease could simply shift his attention to another, like a chef turning from the soup to the entrée." Read more here.

New blood test detects pancreatic cancer earlier than usual

Researchers ar the Kobe University Graduate School of Medicine, Division of Metabolomics, have unveiled a new diagnostic blood test for early screening of pancreatic cancer.  Utilizing metabolomics technology, the blood test measures metabolite levels in order to determine whether or not patients are afflicted with a  pancreatic tumor.  According to lead researcher Dr. Masaru Yoshida, "finding pancreatic cancer earlier means more patients can have the tumor removed and live longer than most patients do now."  Considering that the 5-year survival rate for pancreate cancer is less than 5%, this new approach seeks to detect pancreatic cancer at an early stage, before it metastasizes to the point that it becomes inoperable.
