Universitat Autònoma de Barcelona

MedicalResearch.com: What is the background for this study?

Response: In the last few years some new therapies targeting immune checkpoints have been developed. The programmed death receptor-1 (PD-1) are immune checkpoints that prevent the immune system to act against own tissues. By blocking these mediators it is possible to prevent tumors to escape from the immune system.

About half of the patients receiving these therapies will develop mild to moderate cutaneous adverse events. In the pre-authorization studies for malignant melanoma these include rash, vitiligo, and pruritus. “Rash” has commonly been reported as an adverse event in many oncologic trials evaluating the drugs, without providing further information about the clinical or histological details. Lately, lichenoid eruptions associated to these therapies have been reported and it suggests that an important percentage of these reactions present lichenoid histological features.

James Cancer Hospital
Professor, College of Medicine
Julius F. Stone Chair in Cancer Research
The Ohio State University Columbus, OH

MedicalResearch.com: What do we know about the health effects of cigarette filters? 
Response:  The issue is that the design of the filters makes a cigarette even more dangerous, which can be regulated by the FDA. The issue is not about having a filter, but how they are made. And now we are changing the dialogue to the design of virtually all cigarettes. The holes on the filter are likely one reason the cigarettes of today are more dangerous.

GeneStrat Test Provides Quick Analysis of Genetic Lung Cancer Mutations

MedicalResearch.com Interview with:
Hestia Mellert, PhD

Director, Molecular Product Development

Boulder, CO

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Identifying specific genetic mutations in non-small cell lung cancer patients helps clinicians choose the best treatment options; specific therapies that target mutations can improve patient outcomes, including reducing the risk of death or lessening the severity of the disease. However, nearly 80% of cancer patients do not have genetic mutation results available at initial oncology consultation; up to 25% of patients begin treatment before receiving their results. These factors hinder physicians’ ability to pursue optimal treatment strategies.

This study found that a blood-based assay, the GeneStrat test, provides results in 72 hours for 94% of patients, which expands testing options, and supports faster treatment decisions by physicians.

Cost Effectiveness of Lung Cancer Screening Requires Careful Patient Selection

MedicalResearch.com Interview with:
Kevin ten Haaf MSc

Scientific researcher, Public Health
Erasmus Medical Center
Rotterdam

MedicalResearch.com: What is the background for this study?

Response: Lung cancer screening is currently recommended in the United States, for persons aged 55 through 80 who smoked at least 30 pack-years (the average number of cigarettes smoked per day multiplied by the number of years the person has smoked) and who currently smoke or have quit within the last 15 years. Other countries, such as Canada, are investigating the feasibility of implementing lung cancer screening policies.

However, the cost-effectiveness of lung cancer screening in a population-based setting is uncertain. Concerns have been raised on the feasibility of implementing lung cancer screening policies, especially with regards to the potential costs. In this study, the benefits, harms and costs of implementing lung cancer screening in the province of Ontario, Canada were assessed.

MedicalResearch.com: What is the background for this study?

Response: In December 2013, the United States Preventive Services Task Force (USPSTF) recommended annual screening for lung cancer with low dose computed tomography (LDCT) for current or former heavy smokers who quit within the past 15 years.

A previous study estimated that only 2-4% of heavy smokers received LDCT for lung cancer screening in 2010 in the United States. We sought to determine whether lung cancer screening among high risk smokers increased in 2015, following the USPSTF recommendation in 2013.

MedicalResearch.com: What is the background for this study? 

Response: The U.S. Preventive Services Task Force recommends annual lung cancer screening with low-dose computed tomography (LDCT) for current and former heavy smokers ages 55 to 80.

However, clinicians have questioned the practical aspects of implementing lung cancer screening. VA provides care for 6.7 million Veterans each year, mostly older men – many of whom are current or former smokers – thus the implementation of a lung cancer screening program for VA patients would require substantial resources. In order to understand the feasibility and implications of this for patients and clinical staff, VA implemented a three-year Lung Cancer Screening Demonstration Project (LCSDP) in eight geographically-diverse VA hospitals. Investigators identified 93,033 primary care patients at eight sites who were assessed on screening criteria, of whom 2,106 patients were screened between July 2013 and June 2015.

MedicalResearch.com: What is the bottom line for incidence and mortality trends?

Response: The bottom line for cancer mortality is that in contrast to many other major causes of death, cancer death rates continue to decline, dropping by 25% from 1991 to 2014. This translates to about 2 million fewer cancer deaths over this time period than would be expected if cancer death rates had remained at their peak. Death rates are the best measure of progress against disease.

Cancer incidence rates also dropped in men over the past decade of data, whereas in women they are flat. The drop in men is because of large declines for the top 3 cancers (prostate, lung, and colorectum), which account for more than 40% of cancers diagnosed in men. The stable trend in women is largely because declines in lung and colorectal cancers are offset by a flat trend for both breast and uterine corpus (i.e., endometrial) cancers, which combined account for almost 40% of cases in women, as well as rapid increases for thyroid cancer over the past decade — increasing by almost 5% annually. Importantly, thyroid incidence rates have stabilized in the past few data years because of modifications in diagnostic criteria.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: LURET is multicenter, single-arm, phase II study to evaluate the efficacy and safety of vandetanib as RET inhibitor in patients with advanced RET-rearranged non-small-cell lung cancer (NSCLC). In 2012, RET rearrangements were identified as rare oncogenic alterations for NSCLC.

Among 17 eligible patients included in primary analysis, the objective response rate was 53% (95% CI 28–77), which met the primary endpoint. At the data cutoff, median progression-free survival was 4.7 months (95% CI 2.8–8.5). Overall, vandetanib was tolerated, with an adverse event profile similar to those seen in previous large population studies of vandetanib in patients with unselected NSCLC.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: LUME-Meso II is an international study designed to evaluate the safety and efficacy of nintedanib plus pemetrexed/cisplatin, followed by nintedanib versus placebo plus pemetrexed/cisplatin, followed by placebo, for the treatment of patients with unresectable malignant pleural mesothelioma (MPM).

MPM is a rare cancer that affects the cells that make up the mesothelium of the pleura – the lining or membrane that covers and protects the lungs. It represents less than 1% of all cancers and is often related to long-term asbestos exposure.

A significant improvement in progression-free survival (PFS), the study’s primary endpoint, was observed for patients receiving nintedanib plus chemotherapy compared to patients receiving placebo plus chemotherapy.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Analysis of past randomized clinical trials involving patients with brain metastases, an extremely heterogeneous population, suggested that the stratification tools of the past were inadequate to ensure those trials were comparing similar patients which made the results of those trials difficult to interpret or misleading.

So, in 2008, a new prognostic index, the Graded Prognostic Assessment (GPA) was designed and published to more accurately predict survival. In 2010, the GPA was refined when we learned survival and the factors that predict survival varied by diagnosis (i.e. lung, breast, melanoma, kidney cancer patients with brain metastases had different survival). Now we have learned survival also varies by gene mutations and the diagnosis-specific GPA for lung cancer is further refined in this article with this new information, specifically EGFR and ALK gene alterations. 27 co-authors from 12 academic medical centers contributed patients to this database which represents the largest study of lung cancer patients with brain metastases ever reported.
