Megan A. Adams, MD Gastroenterology Fellow University of MichiganMedicalResearch.com Interview with Megan A. Adams, MD Gastroenterology Fellow University of Michigan   Medical Research: What are the main findings of the study? Dr. Adams: Surveys of doctors indicate that their fear of a malpractice lawsuit for missing a diagnosis of esophageal cancer might drive the overuse of tests called upper endoscopies in patients who are at low risk for the cancer. To examine whether this perception of medical liability risk accurately reflects the real likelihood of a malpractice claim, we looked at a national database of malpractice claims, and compared the rate of claims for delay in diagnosis of esophageal cancer in patients without alarm symptoms (weight loss, dysphagia, iron deficiency anemia), with the rate of claims alleging performance of an upper endoscopy without a good reason for performing the procedure. The database contained 278,220 claims filed against physicians in 1985-2012. The incidence of reported medical liability claims for failure to screen for esophageal cancer in patients without alarm features was quite low (19 claims in 11 years, 4 paid). In contrast, there were 17 claims in 28 years for complications of upper endoscopies with questionable indication (8 paid).

Georgina Long BSc PhD MBBS FRACP Associate Professor of Melanoma Biology and Translational Research Melanoma Institute Australia and the University of Sydney MedicalResearch.com Interview with: Georgina Long BSc PhD MBBS FRACP Associate Professor of Melanoma Biology and Translational Research Melanoma Institute Australia and the University of Sydney Medical Research: Could you provide some background on this project? Why did you decide to do this research project? What prior work led up to this latest paper? Dr. Long: Pre-clinically, we had data that showed that the combination of BRAF inhibitor + MEK inhibitor
  • Decreased skin proliferative toxicity seen with BRAF inhibitors alone (seen as hyperproliferative lesions in rats)
  • and delayed the emergence of resistance I.e. The tumours in the mice reduced in size more, and stayed reduced for longer.We then confirmed this concept in a randomised phase 2 study, although it was not powered for a definitive progression free survival (PFS_ difference like a phase 3 trial is, we saw a strong difference in response rate and in PFS, yet there were only 54 patients per arm.

Giuseppe Curigliano M.D. Ph.D. Medico Direttore, Director Divisione Sviluppo Nuovi Farmaci per Terapie Innovative Early Drug Development for Innovative Therapies Division Via Ripamonti, MilanoMedicalResearch.com Interview with: Giuseppe Curigliano M.D. Ph.D. Medico Direttore, Director Divisione Sviluppo Nuovi Farmaci per Terapie Innovative Early Drug Development for Innovative Therapies Division Via Ripamonti,  Milano Medical Research: What are the main findings of the study? Dr. Curigliano: In the CLEOPATRA study, 808 patients from 25 countries with HER2-positive metastatic breast cancer were randomised to receive first-line placebo/trastuzumab/docetaxel or pertuzumab/trastuzumab/docetaxel. Randomisation was stratified by geographic region and neo/adjuvant chemotherapy. At ESMO 2014 the CLEOPATRA researchers reported results of a final prespecified OS analysis (February 2014). This overall survival (OS) analysis was planned when ≥385 deaths were reported. The log-rank test, stratified by prior treatment status and geographic region, was used to compare OS between arms, applying the threshold of p ≤ 0.0456. Subgroup analyses of OS were performed for stratification factors and other key baseline characteristics.At median follow-up of 50 months (range 0 to 70 months), the statistically significant improvement in OS in favour of pertuzumab/trastuzumab/docetaxel arm was maintained (HR = 0.68, p = 0.0002). Median OS was 40.8 months in the placebo arm and 56.5 months in the pertuzumab arm, with difference of 15.7 months. The PFS in pertuzumab arm was 18.7 vs 12.4 months in placebo arm, HR 0.68 (p < 0.0001).

Mario Mandalà, MD Unit of Clinical Research Department of Oncology and Haematology Papa Giovanni XXIII Hospital Piazza OMS 1, 24100, Bergamo, ItalyMedicalResearch.com Interview with: Mario Mandalà, MD Unit of Clinical Research Department of Oncology and Haematology Papa Giovanni XXIII Hospital Piazza OMS 1, 24100, Bergamo, Italy Medical Research: What are the main findings of the study? Dr. Mandalà: We evaluated PD-L1 expression by IHC in 81 consecutive metastatic melanoma patients, with well-defined demographic and clinical characteristics. Protein expression levels were correlated with clinical outcome. PD-L1+ and PD-L1- subsets of the A375 cell line were stabilized in vitro and compared using gene expression profiling and functional assays. Results were confirmed using xenograft models. In our study PD-L1 membrane positivity was an independent negative prognostic marker. Furthermore PD-L1 expression defined a subset of the BRAF-mutated A375 cell line characterized by a highly invasive phenotype and by enhanced ability to grow in xenograft models. If confirmed, our clinical and experimental data suggest that PD-L1+ melanomas should be considered a disease subset with distinct genetic and morpho-phenotypic features, leading to enhanced aggressiveness and invasiveness.

Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's Queensland University of Technology Queensland, AustraliaMedicalResearch.com Interview with: Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's Queensland University of Technology Queensland, Australia   Medical Research: What are the main findings of the study? Dr Batra: Prostate cancer is a disease with upto 40% genetic component. Previous Genome-wide association studies have identified 77 risk loci associated with prostate cancer. This study is further extension of previous GWASs and also involved meta-analysis of multi-ethnic populations. Through this large study involving approximately 90,0000 individuals, 23 new susceptibility loci were identified to be associated with prostate cancer, 15 variants were identified among men of European ancestry, 7 were identified in multi-ancestry analyses and 1 was associated with early-onset prostate cancer.

Judith Trotman MBChB, FRACP, FRCPA Associate Professor Concord Hospital University of Sydney, AustraliaMedicalResearch.com Interview with: Judith Trotman MBChB, FRACP, FRCPA Associate Professor Concord Hospital University of Sydney, Australia Medical Research: What are the main findings of the study? Dr. Trotman: That PET-CT (applying the cut-off of ≥4 on the now internationally recommended 5 Point Scale) is a more powerful predictor of both Progression Free and Overall Survival than conventional CT in patients responding to first line immunochemotherapy for advanced follicular lymphoma.  It is also a much stronger predictor than the pre-treatment prognostic indices FLIPI and FLIP2. Patients who achieve PET-negative status have a median PFS over 6 years compared to only 17 months in those who remain PET-positive.

Blake Cady MD Professor Emeritus of Surgery Brown UniversityMedicalResearch.com Interview with: Blake Cady MD Professor of Surgery (emeritus) at Harvard Medical School Partners HealthCare, Harvard Medical School institutions, Boston Medical Research: What are the main findings of this study? Dr. Cady:  Our findings support mammography screening, and our data is consistent with the randomized trials. Breast cancer screening with mammography is the most extensively researched screening method ever studied. Only one  “randomized" trial failed to show reduced mortality, (Canadian NCSS studies),  and there were major flaws in its design and execution that negate their results, as noted in multiple critical publications (volunteers, not geographic assignment, palpable masses detected at examination assigned to “screening” arm, large contamination bias (control group got screened anyway), and very poor quality of mammography). Yet it is this NCSS study that is cited by critics and the press.  “Failure Analyses” look backward from death, rather than forward from assignment in randomized trials. The concept of failure studies is well established as noted in recent reports of air-bag failures in cars, and many industrial studies. Seat belt prevention of deaths was discovered by police recording injuries and deaths in crashes after the fact - a failure analysis - not by randomized clinical trials. In breast cancer, failure analyses have advantages of little cost, early results, simplicity, and convenience, compared to randomized trials. Since our results support findings from randomized clinical trials (RCT), they can be accepted as reliable and accurate. Our findings show that about 71% of deaths from breast cancer occur in the  approximately 20% of our patients not in regular screening programs, while only 29% of deaths occur in the 80% of women who were regularly screened by mammography. By extrapolation, women regularly screened have only about a 5% breast cancer mortality, but women not screened have close to a 50% mortality. (This is my extrapolation from our data, not direct data from our “Failure Analysis”)

Dr. Jun Li, MD, PhD, MPH Epidemiology and Applied Research Branch Division of Cancer Prevention and Control National Center for Chronic Disease Prevention and Health PromotionMedicalResearch.com Interview with: Dr. Jun Li, MD, PhD, MPH Epidemiology and Applied Research Branch Division of Cancer Prevention and Control National Center for Chronic Disease Prevention and Health Promotion Medical Research: What are the main findings of the study? Dr. Li: Using the 2001 to 2009 National Program of Cancer Registries (NPCR) and Surveillance, Epidemiology, and End Results (SEER) data, which represent 94.2% of the US population, we identified 120,137 pediatric cancer cases with an incidence rate of 171 cases per million children and adolescents. Overall cancer incidence rates were stable from 2001-2009. However, we found rates were increasing significantly at 1.3% per year in African American children and adolescents.  This increase might be partially attributed to the rise among renal tumors and thyroid cancer. We also found rising incidence in thyroid cancer and renal carcinoma among children and adolescents. As has been previously established, pediatric cancer is more common in males, in white, in adolescents, and in the Northeast. Leukemia is the most common pediatric cancer, followed by central nervous system (CNS) neoplasms, and then lymphomas.

Nienke de Glas, MD PhD-student Leiden University Medical Center Department of Surgery Leiden The NetherlandsMedicalResearch.com Interview with: Nienke de Glas, MD PhD-student Leiden University Medical Center Department of Surgery Leiden The Netherlands Medical Research: What are the main findings of the study? Dr. de Glas: It remains unclear whether mass breast cancer screening has a beneficial effect in older women. In the Netherlands, the upper age limit of the breast cancer screening program was extended from 69 to 75 years in 1998. If a screening program is effective, it can be expected that the incidence of early stage tumours increases, while the incidence of advanced stage tumours decreases. The aim of this study was to assess the incidence of early stage and advanced stage breast cancer before and after the implementation of mass screening in women aged 70-75 years in the Netherlands. We showed that the extension of the upper age limit to 75 years has only led to a small decrease of advanced stage breast cancer, while the incidence of early stage tumours has strongly increased. For every advanced stage tumour that was prevented, 20 “extra” and early stage tumours were diagnosed.

[caption id="attachment_7562" align="alignleft" width="125"]Department of Pathology St. Jude Children's Research Hospital Memphis, TN 38105 St. Jude Children's Research Hospital[/caption] MedicalResearch.com Interview with: Dr. Charles Mullighan, M.D., MBBS(Hons), MSc Department of Pathology St. Jude Children's Research Hospital Memphis, TN 38105 MedicalResearch: What are the most important take home points from this study for practicing clinicians and their patients? Dr. Mullighan: Acute lymphoblastic leukemia (ALL) remains a leading cause of cancer death in children, and the prognosis worsens with increasing age. Current therapies are inadequate for many patients. This study has defined the genetic basis of a recently described subtype of Acute lymphoblastic leukemia called Ph-like ALL. We show that the prevalence increases with rising age, and that in both children and young adults the disease is driven by a diverse range of genetic changes that activate kinase signaling, which fuels the growth of leukemia cells. Ph-like Acute lymphoblastic leukemia currently has a poor outcome. The activated kinases may be inhibited by currently approved tyrosine kinase inhibitors (TKIs). We have shown efficacy of these inhibitors in cell lines and experimental models, and in a series of patients with Ph-like Acute lymphoblastic leukemia treated with TKIs.

Dr. Constance Brinckerhoff Professor of Medicine Professor of Biochemistry Geisel School of Medicine at DartmouthMedicalResearch.com Interview with: Dr. Constance Brinckerhoff Professor of Medicine Professor of Biochemistry Geisel School of Medicine at Dartmouth Medical Research: What are the main findings of the study? Dr. Brinckerhoff: The genetic mutation BRAFV600E , frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease’s progression. Targeting this mutation with Vemurafenib reduces this interaction, and suggests possible new treatment options for melanoma therapy.
Author Interviews, Cancer Research, Genetic Research, University of Pennsylvania / 12.09.2014

MedicalResearch.com Interview with: Renata Afi Rawlings-Goss, Ph.D. Postdoctoral Fellow Tishkoff Lab, University of Pennsylvania Medical Research: What are the main findings of the study? Dr. Rawlings-Goss: We found genetic mutations in key gene regulators that have been linked to ethnic disparities in cancer. Our investigation identified more than 30 previously undescribed mutations in important regulatory molecules called microRNAs. Individual microRNA molecules can regulate large numbers of genes in some cases over 6000 genes at once. Therefore, mutations in these genes have been linked to numerous diseases. By and large, however, microRNA mutations have not been studied in people of diverse ethnic backgrounds.

MedicalResearch.com Interview with: Dr. Giulia Scioscia Coauthor of this study with the Prof. Carpagnano University of Foggia. Medical Research: What are the main findings of this study? Dr. Scioscia: The principal and newest findings of our study are:
  • Airways inflammation and neoangionesis are critical component of the lung cancer pathogenesis and they contribute to the regulation of airways temperature. They cause a regional hyperthermia in the lung lesion.
  • The exhaled Breath temperature has been proven to be the expression of the airways temperature and for this reason of their inflammation and neoangionesis.
  • For the first time we have measured this hyperthermia in lung cancer patients with the xhalo. The patient with diagnosis of tumor shows an higher temperature than in healthy ones and this values correlate with cigarette smoking and tumor progression.

Professor Huang: In this meta-analysis of 16 prospective cohort studies comprising more than 890,000 individuals, we found that the presence of prediabetes at baseline associated with a 15% increased risk of cancer overall. The results were consistent across cancer endpoint, age, duration of follow-up and ethnicity. There was no significant difference for the risk of cancer with different definitions of prediabetes (impaired fasting glucose [IFG] and/or impaired glucose tolerance [IGT]).

MedicalResearch.com Interview with: Karin Jors MA Department of Palliative Care, Comprehensive Cancer Center, University Medical Center Freiburg, Freiburg, Germany Medical Research: What are the main findings of the study? Answer: The findings of our study shed light on the current circumstances for dying in cancer centers. Physicians and nurses in our study reported that they rarely have enough time to care for dying patients. In addition, only a minority of staff members felt that they had been well-prepared during their training to care for dying patients and their families. Overall, only 56% of participants indicated that it is usually possible for patients to die in dignity on their ward. This is likely the result of various factors such as: inadequate rooms for dying patients and their families (i.e. shared rooms), poor communication with patients regarding burdensome treatments, an overuse of life-prolonging measures, etc. Striking differences were found between the responses of palliative care staff and staff from other wards (e.g. general care, oncology, intensive care). For example, palliative care staff reported that they usually have enough time to care for dying patients. In addition, 95% of palliative care staff indicated that it is usually possible for patients to die in dignity on their ward. Overall, nurses perceived the situation for dying patients more negatively than physicians. Whereas 72% of physicians reported that patients can usually die a dignified death on their ward, only 52% of nurses shared this opinion. Although only slightly more than half of participants believed that patients can usually die in dignity on their ward, this is a considerable improvement to the situation 25 years ago. In a similar study published in 1989, researchers found that 72% of physicians and nurses experienced the situation for patients dying on their hospital ward as undignified.

Paula Berstad, PhD, postdoc Telemark Hospital c/o Cancer Registry of Norway Oslo, NorwayMedicalResearch.com Interview Invitation Paula Berstad, PhD, postdoc Telemark Hospital c/o Cancer Registry of Norway Oslo, Norway   Medical Research: What are the main findings of the study? Dr. Berstad: In general population of age 50-55 years, both those invited to bowel cancer screening in year 2001 by flexible sigmoidoscopy and those not invited improved their lifestyle from year 2001 to 2012. Lifestyle was measured as adherence to public health guidelines; non-smoking, daily physical exercise, healthy diet and normal body weight. However, the 11-year improvement was smaller in those who were screened for bowel cancer compared to those not screened. Further, among those who attended the screening, the improvement was smaller in those with findings at screening (positive screening result) compared to those without findings (negative screening result). Our interpretation of the findings is that bowel cancer screening may have a small unwanted effect on lifestyle. Particularly, attention should be given to lifestyle among those testing positive at screening.

Ying Wang PhD Epidemiology Post-Doc Fellow American Cancer Society Inc Atlanta, GA 30303MedicalResearch.com Interview with:  Ying Wang PhD Epidemiology Post-Doc Fellow American Cancer Society Inc Atlanta, GA 30303 Medical Research: What are the main findings of the study? Dr. Wang: Previous studies suggest that higher intake of fruits and vegetables are associated with lower risk of breast cancer risk, especially estrogen receptor (ER) negative (ER-) tumors that are more aggressive and difficult to treat. We found that postmenopausal women who had higher intake of flavones, a subgroup of flavonoids that are widely distributed in fruits and vegetables, had lower risk of breast cancer. Furthermore, higher intake of flavan-3-ols which is high in non-herbal tea was associated with lower risk of ER- but not ER positive breast cancer.

Dr. Thorat : Accumulating evidence supports an effect of aspirin in reducing cancer incidence and mortality. Our analyses show that for average-risk individuals aged 50-65y taking aspirin for 10 years, there would be a relative reduction of between 7% (women) and 9% (men) in the number of cancer, myocardial infarction or stroke events over a 15 year period and an overall 4% relative reduction in all deaths over a 20 year period. The benefits of aspirin use would be most visible in the reduction in deaths due to cancer. If the findings of our study are applied to the UK general population aged 50-64 taking aspirin for next 10 years, on an average more than 6000 lives will be saved every year.

Frank van Hees, MSc Researcher, Department of Public Health, Erasmus MC Rotterdam, The NetherlandsMedicalResearch.com Interview with: Frank van Hees MSc Erasmus University Medical Center Rotterdam, the Netherlands   Medical Research: What are the main findings of the study? Answer: Many U.S. elderly are screened for colorectal cancer more frequently than recommended: One in every five elderly with a negative screening colonoscopy result undergoes another screening colonoscopy within 5 years’ time instead of after the recommended 10 years. Moreover, one in every four elderly with a negative screening colonoscopy result at age 75 or older receives yet another screening colonoscopy at an even more advanced age. Our study shows that, in average risk individuals, these practices are not only a waste of scarce health care resources: often they are also associated with a balance among benefits, burden, and harms that is unfavorable for those being screened.

Devanand Sarkar, M.B.B.S., Ph.D Harrison Scholar at VCU Massey Cancer Center, Blick Scholar and Associate Professor Department of Human and Molecular Genetics Member of the VCU Institute of Molecular Medicine Virginia Commonweath School of MedicineMedicalResearch.com Interview with: Devanand Sarkar, M.B.B.S., Ph.D Harrison Scholar at VCU Massey Cancer Center, Blick Scholar and Associate Professor Department of Human and Molecular Genetics Member of the VCU Institute of Molecular Medicine Virginia Commonweath School of Medicine Medical Research: What are the main findings of the study? Dr. Sarkar: Retinoic acid (Vitamin A) is an anti-cancer drug for a number of cancers including liver cancer. However, all patients do not respond to retinoic acid. Astrocyte elevated gene-1 (AEG-1) is overexpressed in a large percentage of cancer patients and promotes development and progression of cancer. In this study we document that AEG-1 inhibits retinoic acid function. Combinatorial strategy involving AEG-1 inhibition and retinoic acid synergistically blocks growth of human liver cancer cells in animal models.
