EMA recommends granting a marketing authorisation for pegylated liposomal formulation of Irinotecan for metastatic pancreatic adenocarcinoma

On 21 July 2016, the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending granting a marketing authorisation for the medicinal product Onivyde (pegylated liposomal formulation of irinotecan), intended for the treatment of metastatic adenocarcinoma of the pancreas.

Onivyde contains irinotecan in a pegylated liposomal formulation.

When added to 5-fluorouracil (5-FU) 2,400 mg/m2 and leucovorin (LV) 400 mg/m2, Onivyde improved survival compared with 5-FU 2,000 mg/m2 and LV 200 mg/m2.

Nephrectomy for RCC may result in significant declines in renal function

Despite having better baseline kidney function and overall health status, patients with renal cell carcinoma (RCC) had greater postsurgical decreases in kidney function after undergoing a radical nephrectomy compared with patients undergoing a radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).

These results were published recently in Urology. According to the study, surgical management of both RCC and UTUC involves radical removal of a renal unit, with the additional removal of the ureter in patients with UTUC. With this study, the researchers hoped to identify risk factors that predict a decline in renal function after radical nephrectomy for RCC or RNU for UTUC.

Scans not worthwhile for most thyroid cancers

According to a new study conducted at the University of Michigan, undergoing scans after treatment does not improve survival changes of thyroid cancer patients.  According to study researcher Dr. Megan Haymart, this study, conducted on more than 28,000 thyroid cancer patients between 1998-2011, shows that "for the most part, this imaging isn't affecting survival."  Further, while a small number of thyroid cancers are aggressive and likely to return, overall, 96% of patients with thyroid cancer continue to live more than 10 years after first being diagnosed.

In vitro fertilization does not raise risk for breast cancer

Researchers at the Netherlands Cancer Institute in Amsterdam have discovered that women undergoing in vitro fertilization (IVF) are not at increased risk of developing breast cancer. Findings from the Dutch study conducted on more than 25,000 women found that "the cumulative rate of breast cancer was 3% for the IVF group, compared to 2.9% for the non-IVF group."

Analytical studies branch research paper series – health and work in the family: evidence from spouses’ cancer diagnoses

Changes in health status may affect not just the individuals who experience such changes, but also their family members. For example, if the main earner in a family loses his or her ability to generate income due to a health shock, it invariably affects the financial situation of the spouse and other dependants. This study analyzes how one spouse’s cancer diagnosis affects the employment and earnings of the other spouse and (before-tax) total family income using administrative data from Canada.

PET-CT–guided surveillance may reduce need for surgery in some patients with advanced head and neck cancer

Patients with advanced squamous cell carcinoma of the head and neck who underwent PET-CT imaging after chemoradiation to determine if they still needed to have surgery had overall survival rates similar to those of patients who underwent planned neck dissection and chemoradiation. PET-CT imaging also resulted in fewer operations and was more cost-effective.

Study forecasts ‘Silver Tsunami’ of cancer survivors

The number of long-term cancer survivors has continued to grow over the past several decades. With this growth has come the recognition that many cancer survivors have unique health care needs as a consequence of their cancer or the treatments they received.

To better understand the composition of the cancer survivor population and their other medical conditions, or comorbidities, the researchers made projections based on data from NCI’s Surveillance, Epidemiology, and End Results (SEER) program, including the SEER-Medicare linked database, and the U.S. Census Bureau.

A unique aspect of the study, published July 1 in Cancer Epidemiology, Biomarkers & Prevention, was that the researchers were able to assess specific cancer burden by age groups of older survivors.

How much does cancer prevention cost?

There are many indicators used in health care to assess the value of a public health intervention, and one frequently-used metric is cost effectiveness. This indicator involves calculating a ratio that measures the balance between cost and health benefits that are not monetized (typically, lives saved).

Euthanasia and physician-assisted suicide increasingly being legalized, although still relatively uncommon

Euthanasia and physician-assisted suicide in the United States, Canada, and Europe are increasingly being legalized, but they remain relatively rare, and primarily involve patients with cancer, according to a study appearing in the July 5 issue of JAMA.

The authors found that between 0.3 percent to 4.6 percent of all deaths are reported as euthanasia or PAS in jurisdictions where they are legal. The frequency of these deaths increases after legalization. More than 70 percent of cases involved patients with cancer. Typical patients are older, white, and well-educated.

Cancer patients, doctors often disagree about prognosis

Those with advanced disease are likely to be more optimistic than their doctor, study shows.

Cancer patients and their doctors often hold different opinions about the patient's chances for survival and how long he or she might live, according to a new study published July 14 in the journal JAMA Oncology. The study found that 68 percent of patients rated their odds for survival differently from their doctors. Almost all patients were more optimistic than their doctor. Of the 68 percent, only 10 percent understood that their views and their doctor's differed.

Risks for breast, ovarian cancers could be found with multigene panel testing

In nearly 100,000 patients who were clinically tested for hereditary cancer risk, utilization of multigene panel sequencing was found to detect ovarian cancer-associated mutations in 11 genes, according to results of a study presented at the 2016 ASCO Annual Meeting.

A second study, also presented at the meeting2, examined the potential harms of multiplex testing for cancer risk, such as unwarranted surgery or adverse psychological effects. However, results showed that, at a 3-month follow-up after genetic testing, the rates of patient distress, intrusive thoughts, or regret of testing were found to be low.

The unbearably slow adoption of genetic cancer tests

Over the past 20 years, Nazneen Rahman, professor and Head of the Division of Genetics and Epidemiology at the Institute of Cancer Research, has identified a steady stream of genes that influence the risk of breast, ovarian, and childhood cancers. But her latest accomplishment, and one of her proudest, is very different. Rahman has created a shortcut in the British healthcare system that will give women with ovarian cancer access to a critical genetic test. The new pathway is cost-efficient, saving time and money as well as lives.

Regulations issued by FDA for next-generation sequencing use

The utilization of next-generation sequencing (NGS)—which can examine millions of DNA variants at one time—is now being regulated. The FDA has released 2 draft guidances regarding the use of these NGS-based tests, which can be used to inform risk and treatment decisions across multiple tumor types.

The first draft guidance, titled, “Use of Standards in FDA’s Regulatory Oversight of Next Generation Sequencing (NGS)-Based In Vitro Diagnostics (IVDs) Used for Diagnosing Germline Diseases” provides recommendations for designing, developing, and validating NGS-based tests for rare hereditary disease.

The second draft guidance, titled, “Use of Public Human Genetic Variant Databases to Support Clinical Validity for Next Generation Sequencing (NGS)-Based In Vitro Diagnostics” describes an approach wherein test developers may rely on clinical evidence from FDA-recognized public genome databases to support clinical claims for their tests and provide assurance of accurate clinical interpretation of genomic test results.

The guidances are part of the of the FDA’s engagement in the Precision Medicine Initiative (PMI), created by the White House in early 2015.

“Targeting the right treatments to the right patients at the right time is the goal of the President’s Precision Medicine Initiative,” said FDA commissioner Robert Califf, MD, in a statement. “Soon, patients will have a much more complete picture of their health than in the past, informed by their genetic and genomic makeup.

Statin treatment linked to fewer cancer deaths

Being treated for high cholesterol with statins is being linked with a reduced risk of death and better survival from four common cancers. The results come from a study of 14 years of UK data that included nearly a million people.

Data on deaths from cancers came from the Office for National Statistics. When researchers from several UK centres analysed the data, they found that people diagnosed with high cholesterol and one of the four cancers were less likely to die from cancer.
However, being diagnosed with high cholesterol usually lead to treatment, often with statins.

The study could only find a link between high cholesterol and a lower death risk, rather than establishing any cause-and-effect.

Promising initial trial of immunotherapy agent in anal cancer

A study of nivolumab (Opdivo) in patients with squamous cell carcinoma of the anal canal (SCCA), which recently presented findings at the 2016 World Congress on Gastrointestinal (GI) Cancer, is the first prospective trial to examine immunotherapy agents in the treatment of SCCA.

Approximately 80% to 95% of cases are linked to human papillomavirus (HPV) infection. "The role of HPV in the tumorigenesis of SCCA provides rationale for the use of immune checkpoint agents as a novel therapy for patients with a virally driven disease." noted lead author Cathy Eng, MD, professor of gastrointestinal medical oncology at the University of Texas MD Anderson Cancer Center and co-leader of MD Anderson's HPV-related Cancer Moon Shot.
