Lapatinib or trastuzumab not recommended as first-line treatment for metastatic breast cancer patients

After revieving  the internactions of lapatinib or trastuzumab in combination with an aromatase inhibitor for metastatic breast cancer patients, NICE has concluded that lapatinib and trastuzumab "do not provide enough benefit to patients to justifty their high costs."  Despite special considerations looking at extending lives of people with this cancer, no definite benefits could be found.  As a result, does not recommend lapatinib or trastuzumab as a course of treatment.

Erlotnib: First-line treatment of locally advanced or metastatic non-small cell lung cancer

The National Institute for Health and Clinical Excellence (NICE) recommends erlotnib as a first-line treatment for patients afflicted with locally advanced or metastatic non-small-cell lung cancer.  NICE notes that erlotnib should, in particular, be prescribed to patients testing positive for mutations to tyrosine kinase (an epidermal growth factor receptor).  NICE has studied the effects of erlotnib, both in treatment potential and associated costs.  It recommends ernotlib since "it works as well as other treatments available...and costs about the same."

Novel chemotherapy agent mimics human pancreatic ductal adenocarcinoma

Preclinical results presented at the American Association for Cancer Research's Pancreatic Cancer: Progress and Challenges Conference (held June 18-21, 2012 at Lake Tahoe, USA), unveiled a chemotherapeutic agent, MEK 1/2 inhibitor BAY 86-9766, to help understand the progression of pancreatic cancer.  Using mice as test subjects, researchers at the Technical University in Munich have shown that MEK 1/2 "led to dramatic tumor shrinkage after only one week of treatment."  While this study is thus far only in the preclinical stage, results are promosing and may lead to an improved course of treatment for patients afflicted with pancreatic cancer.

Interim analysis of a randomized phase III study of abiraterone acetate in chemotherapy-naive patients with metastatic castration resistant prostate cancer

In patients with asymptomatic or mildly symptomatic chemotherapy-naive metastatic castration resistant prostate cancer, abiraterone acetate plus prednisone produced a statistically significant benefit in radiographic progression-free survival over placebo plus prednisone, according to a planned interim analysis of the randomized, phase III, multicenter, COUAA-302 study. The results were presented by Dr Charles Ryan of the Helen Diller Family Comprehensive Cancer Center, University of California, San Francisco, USA at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago (1 - 5 June 2012). With 43% of total events reported in the COUAA-302 study, the independent data monitoring committee concluded that the co-primary endpoints of overall survival and radiographic progression-free survival and secondary endpoints all favored the abiraterone acetate arm and unanimously recommended unblinding the study and crossing patients over from placebo to abiraterone acetate treatment.

Study of available cancer cell lines shows that many are mislabelled or contaminated

Researchers stress how easy and important it is to verify cell lines before use. Modern cancer therapies start in cells – researchers compare cancer samples to healthy cells to discover how cancer is genetically different, and use cell lines to test promising new drugs. However, a University of Colorado Cancer Center study published in the journal Gynecologic Oncology shows that due to a high rate of contamination, misidentification and redundancy in widely available cell lines, researchers may be drawing faulty scientific conclusions.

Implementing a tool to identify risk for venous thromboembolism in cancer patients

Clinical trial summary: Cancer increases the risk of deep vein blood clots and clots traveling to the lungs (emboli) which cause morbidity (leg swelling, pain, and shortness of breath), sudden death, delays cancer treatment, and decreases cancer survival by 66% compared to similar cancer patients without blood clots. Blood thinners may prevent clots but major bleeding is also a problem, so preventive therapies are not used routinely. Identifying patients at highest risk for clots is critical. A tool exists but it has not been used outside of research. Study is proposed to determine how to apply this tool in clinical practice and test if it works. Read more here.

The effect of perioperative non-steroidal anti-inflammatory drug Naproxen on pleural effusion formation after lung resection

Clinical trial summary: Following a lung resection procedure, patients have their pleural space drained of fluid that accumulates due to the severing of proximal vessels like lymph nodes. The volume of fluid pumped depends on the severity of the inflammation. The study is being conducted to attempt to use painkillers with intrinsic anti-inflammatory action to try and reduce the degree of inflammation in patients' pleural cavity, thus ensuring patients are discharged faster, with a greater comfort level, and a hopefully lower rate of admission.

Federal government drug shortage report falls short in protecting patients

Recommendations in a House of Commons report on drug shortages will not protect patients’ health, and cannot replace decisive government leadership on the issue, says the Canadian Cancer Society. “We are disappointed that the report’s recommendations do not provide strong, concrete action to achieve the goals MPs unanimously called for,” says Paul Lapierre, Vice President, Public Affairs and Cancer Control, Canadian Cancer Society.  “Drug shortages are a national problem, and they will not be resolved without a Canada-wide approach. If the federal government is concerned about the welfare of patients in this country, they must lead the way in developing a nationwide strategy to alleviate drug shortages.” Read the full media release here.

Natural product found in sea sponges shows promise in preventing cancer-induced muscle wasting

Researchers in Montreal have discovered that a chemical found in sea sponges can effectively prevent muscle wasting in mice. The study, funded in part by the Canadian Cancer Society, is published in the journal Nature Communications.

Rapid and durable complete response in patients with newly diagnosed multiple myeloma treated with carfilzomib, lenalidomide, and dexamethasone

A three-drug treatment for multiple myeloma provided rapid, deep and potentially durable responses, researchers reported on June 4 online in Blood, the journal of the American Society of Hematology, and June 3 at the 2012 Annual Meeting of American Society of Clinical Oncology (Chicago, USA). The researchers, led by Dr Andrzej Jakubowiak, professor of medicine and director of the multiple myeloma program at the University of Chicago Medical Center, found that combining carfilzomib, a next generation proteasome inhibitor, with two standard drugs, lenalidomide and low-dose dexamethasone, compared favorably to other frontline regimens. The longer patients stayed on the therapy, the better their response. After at least eight 4-week cycles of treatment, 61% of the 36 patients who remained on the therapy had a stringent complete response, defined as no detectable tumor cells or myeloma protein in the blood or bone marrow; 78% had at least a near complete response. More than 90% of patients had no progression of their disease at two years. See the full report here.

New treatment controls breast cancer growth in study

Researchers have found that a new drug worked better than the standard treatment for keeping a type of advanced breast cancer from worsening. The drug, trastuzumab emtansine (T-DM1), is so far available only through clinical trials. Researchers presented their findings June 2 at the 48th annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. Read the American Cancer Society news item here.

Study finds link between osteoporosis and osteoporosis treatment and a reduced risk of breast cancer recurrence

New research, presented by the NCIC Clinical Trials Group (CTG) at the American Society of Clinical Oncology (ASCO) meeting in Chicago, draws a significant link between the development of osteoporosis, osteoporosis treatment and a reduced risk of breast cancer recurrence. The study involved almost 1,300 postmenopausal women with a diagnosis of early breast cancer who used AIs and who had osteoporosis. The researchers found that the women with osteoporosis experienced improved event-free survival (how effective a treatment is at preventing recurrence) and distant disease-free survival (a measure of how long patients remain free of metastasis at distant sites), pointing to the need to weigh the risks and benefits of treatment with AIs.

Pivotal phase III results of afatinib as first-line treatment in patients with advanced adenocarcinoma of the lung harboring EGFR-activating mutations

Results from LUX-Lung 3, the pivotal phase III randomized, open-label, lung cancer trial investigating the ErbB family blocker afatinib, in patients with EGFR mutations, were presented at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago (1 - 5 June 2012). LUX-Lung 3, which compares afatinib to standard platinum based chemotherapy, is the largest phase III trial in first-line EGFR mutation positive, advanced, metastatic non-small cell lung cancer (NSCLC) patients. LUX-Lung 3 is also the first study using pemetrexed/cisplatin as a comparator. Read the news article here.

AURELIA - the first randomized phase III trial of bevacizumab with standard chemotherapy in platinum-resistant ovarian cancer

Speaking on behalf of the AURELIA investigators (European ovarian cancer research groups), Dr Eric Pujade-Lauraine presented at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago (1 - 5 June 2012) results from the first phase III trial combining bevacizumab with current standard of care - chemotherapy in the treatment of platinum-resistant recurrent ovarian cancer. This study is the first randomized phase III trial to demonstrate benefit with biologic therapy and benefit with combination therapy, rather than monotherapy, in patients with platinum-resistant ovarian cancer. The researchers concluded that bevacizumab combined with chemotherapy should be considered as a new standard of care. Read the news article here.

June issue of WHO Bulletin available online

The June issue of the WHO Bulletin (available here) includes an editorial on the management of non-communicable diseases in low- and middle-income countries and an article on anti-smoking measures and tobacco consumption in Turkey.

WHO: Fighting non-communicable diseases

The World Health Assembly, the decision-making body of the UN World Health Organization (WHO), aims to reduce preventable deaths from non-communicable diseases (NCDs) like diabetes, heart attacks and strokes, chronic respiratory diseases and cancers, by 25 percent by 2025. WHO is coordinating negotiations on the surveillance, indicators and voluntary targets that will form an eventual global plan to fight NCDs, and is drafting recommendations to be considered by member governments in October 2012. Read the IRIN (Integrated Regional Information Networks) news here.

Economist infographic depicts probability of dying from NCDs by country

The Economist's "Graphic Detail" blog features an infographic depicting the probability of dying from a non-communicable disease, by country. "You are more likely to be killed by a non-communicable disease (NCD), like cancer or heart disease, than anything else," the blog notes, adding, "In 2008 they accounted for 63 percent of the 56 million deaths worldwide".

Many US cancer survivors still lost in transition

According to a recent Lancet article, many cancer survivors are still missing out on the close follow-up that they need. Julia Rowland, director of the Office of Cancer Survivorship at the National Cancer Institute (NCI), explains that “there is growing pressure on the oncology community to address care after cancer” now that cancer is increasingly seen as a “chronic illness”. Empowered by their growing numbers (there are 12 million cancer survivors in the USA alone), people who survive cancer are demanding better communication about and coordination of their care, she says.

Approval of sunitinib for gastrointestinal stromal tumors

According to a study conducted at the Dana-Farber Cancer Institute, a key design element present in a phase III clinical trial has led to worldwide approval of sunitinib for treating gastrointestinal stromal tumors (GIST). 

Sunitinib, a small molecule inhibitor of KIT, was approved by the FDA in 2006 for treating patients with imatinib resistant/intolerant GIST. As indicated by this study, clinical trials are essential in understanding the drug development process: "these goals really are possible to achieve by designing studies around the best science and choosing diseases that are deeply understood at a molecular level, such as GIST."

Cancer death rate dropping in Canada

According to the 2012 Canadian Cancer Statistics report, produced by the Canadian Cancer Society, overall cancer death rates have dropped by 21 % (men) and 9% (women) between 1988 and 2007. Despite this encouraging trend, cancer still remains the leading cause of death in Canada. The 2012 report contains updates on cancer incidence, mortality, survival, as well as prevalence and risk of developing or dying from cancer. According to the Canadian Partnership Against Cancer, "systematically recording and tracking these statistics is a key part of understanding the progress being made to address cancer."

Global cancer rates could go up 75% by 2030, study uggests

"The number of people with cancer is set to surge by more than 75 percent across the world by 2030, with particularly sharp rises in poor countries as they adopt unhealthy 'Westernized' lifestyles," according to a study published Friday in the Lancet. "If current population trends continue, the number of people with cancer worldwide will go up to 22.2 million by 2030, up from 12.7 million in 2008," CNN's "The Chart" notes, adding, "Cases are expected to surge in poorer parts of the world, which are ill-equipped to handle the burden"

REMARK checklist for reporting tumor marker studies

Researchers at the University of Oxford have created an explanatory guide detailing how the REMARK (Reporting Recommendations for Tumor Marker Prognostic Studies) can be used with tumor marker prognostic studies. The authors comment that incomplete reporting of prognostic marker studies in cancer happens all too frequently, and believe that using the REMARK Checklist will emphasize that "good reporting reveals the strengths and weakness of a study and facilitaties sound interpretation and application of study results." More information about the REMARK Checklist is available by clicking here.

Cancer survivors who stay active live longer

Can going for a walk improve cancer survivors’ long-term prognosis? It may, according to new research showing that exercise can lower survivors’ risk of premature death, not only from cancer but from any cause. In one report, a major new review published this month in The Journal of the National Cancer Institute, scientists at the agency gathered available studies examining exercise and cancer survivorship, dating to 1950. Most had been published in the past five years. See the full news here.

Many care doctors don't know long-term effects of chemo

From U.S. Health News: Many primary care doctors don't know the long-term side effects of the chemotherapy treatments that cancer survivors under their care may have been given, a new survey found. On the other hand, most oncologists -- though not all -- are familiar with the side effects of four common treatments used to treat breast and colon cancer, according to the results of the survey being presented at the upcoming annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. In the survey both two types of doctors were asked to identify side effects of four commonly used chemotherapy drugs for breast and colon cancer: Adriamycin (doxorubicin); Eloxatin (oxaliplatin); Cytoxan (cyclophosphamide); and Taxol (paclitaxel).

Human development central to changing cancer burden

Such is the conclusion of a study led by scientists of the International Agency for Research on Cancer (IARC) and published Friday 1 June 2012 in the Lancet Oncology(1). Strikingly the study demonstrates not only how an increasing cancer burden will fall predominantly on those countries that are in the process of social and economic transition but also that the type of cancers that are most common is changing. Findings from the population-baseds study: In the highest HDI regions in 2008, cancers of the female breast, lung, colorectum, and prostate accounted for half the overall cancer burden, whereas in medium HDI regions, cancers of the oesophagus, stomach, and liver were also common, and together these seven cancers comprised 62% of the total cancer burden in medium to very high HDI areas. In low HDI regions, cervical cancer was more common than both breast cancer and liver cancer. Nine different cancers were the most commonly diagnosed in men across 184 countries, with cancers of the prostate, lung, and liver being the most common. Breast and cervical cancers were the most common in women. In medium HDI and high HDI settings, decreases in cervical and stomach cancer incidence seem to be offset by increases in the incidence of cancers of the female breast, prostate, and colorectum. If the cancer-specific and sex-specific trends estimated in this study continue, we predict an increase in the incidence of all-cancer cases from 12·7 million new cases in 2008 to 22·2 million by 2030.
