MedicalResearch.com Interview with: Satish Gopal, MD, MPH Program in Global Oncology, Lineberger Comprehensive Cancer Center UNC Project-Malawi, Tidziwe Center, Private Bag A-104, Lilongwe, Malawi MedicalResearch.com: What is the primary message our physician readers should take away from the piece?” Answer: Lymphoma is one of the leading causes of HIV-associated death in the modern ART era. In our analyses of a large multicenter US cohort, survival for HIV-associated lymphoma patients receiving routine care has not clearly improved since the modern ART era began, and remains significantly worse than SEER outcomes for the same lymphoma subtypes in the general population. This was somewhat surprising in an era of normalizing life expectancy for HIV-infected patients on ART, and quite different from the outstanding results achieved for this population in recent clinical trials conducted by AMC and NCI.

Hemodialysis.com Interview with:: Marcela G. del Carmen, M.D., M.P.H Division of Gynecologic Oncology, Vincent Obstetrics and Gynecology Massachusetts General Hospital, 55 Fruit Street, Yawkey 9 E Boston, Massachusetts MedicalResearch.com: What are the main findings of the study? Answer: The study sample included 7,973 women, including 7,363 (92.3%) whites and 610 (7.7%) AA, diagnosed with vulvar cancer from 1973 to 2009. African American women were younger and had a higher rate of distant metastasis compared to white women.  African American women were more likely to be treated by radiaton therapy and less likely to receive survival therapy. Although the study found that compared to white women, African Americans were more likely to be younger and have more advanced disease upon diagnosis, they had lower rates of vulvar cancer related mortality compared to white women.

Dr. Haas: We found that tomosynthesis helped to reduce the number of women who undergo a screening mammogram and are called back for additional imaging and testing. Specifically, the greatest reductions in patients being called back were seen in younger patients and those with dense breasts. Tomosynthesis is analogous to a 3D mammogram, and improves contrast of cancers against the background breast parenchyma. (more…)

Answer: The study shows that people who live at locations with higher levels of particles in the air are at higher risk for development of lung cancer. It seems that there is no threshold for air pollution with particles below which there is no risk; the results show that it is more like “the more air pollution the worse and the less pollution the better”. The strongest association was seen for adenocarcinoma of the lung. (more…)

MedicalResearch.com Interview with: Xiaolu Yang, Ph.D.MedicalResearch.com Interview with: Xiaolu Yang, Ph.D. Professor of Cancer Biology at the Perelman School of Medicine University of Pennsylvania and the Abramson Family Cancer Research Institute, MedicalResearch.com: What are the main findings of the study? Dr. Yang: TAp73 is a structural homologue of the preeminent tumor suppressor p53, but its role in tumorigenesis has been unclear. In this study, we show that TAp73 supports the proliferation of tumor cells. Mechanistically, TAp73 activates the expression of glucose-6-phosphate dehydrogenase (G6PD), a rate-limiting enzyme in the pentose phosphate pathway. This function of TAp73 is required for maintaining a robust biosynthesis and anti-oxidant defense in tumor cells. These finding connects TAp73 to oncogenic growth and suggest that G6PD may be a valuable target for tumor therapy. (more…)

Bosland, DVSc, PhD Professor of Pathology Department of Pathology University of Illinois at Chicago College of Medicine Chicago, IL  60612 MedicalResearch.com: What are the main findings of the study? Dr. Bosland: Daily consumption of a supplement containing soy protein isolate for two years following radical prostatectomy did not reduce recurrence of prostate cancer in men at high risk for this (radical prostatectomy is surgical removal of the prostate to treat prostate cancer). The study showed that this soy supplementation was safe. It is not clear whether this result indicates that soy does not prevent the development of prostate cancer, but men that have the disease probably do not benefit from soy supplementation. (more…)

Melanoma Survival Disadvantage in Young, Non-Hispanic White Males Compared With Females

MedicalResearch.com: What are the main findings of the study? Dr. Swetter: Women diagnosed with melanoma tend to fare better than men in terms of improved survival, and this has mostly been attributed to better screening practices and behaviors in women that result in thinner, more curable tumors, and/or more frequent physician visits in older individuals that result in earlier detection.  Our study focused on survival differences between young men and women (ages 15-39 years) diagnosed with cutaneous (skin) melanoma, who constitute a generally healthy population compared to the older adults that have usually been studied. We found that young men were 55% more likely to die of melanoma than age-matched women, despite adjustment for factors that may affect prognosis, such as tumor thickness, histology and location of the melanoma, as well as presence and extent of metastasis. Our results present further evidence that a biologic mechanism may contribute to the sex disparity in melanoma survival, since adolescent and young adults see physicians less frequently and are less likely to have sex-related behavior differences in skin cancer screening practices than older individuals.

MedicalResearch.com Interview with: Sarah H. O'Connell M.D. PGY-4 Yale New Haven Hospital Yale School of Medicine Department of Diagnostic Radiology MedicalResearch.com:  What are the main findings of the study? Answer: The purpose of our study was to evaluate the visibility of cancers in women at high-risk for breast cancer on 2D mammography compared to digital breast tomosynthesis. In other words, how would the use of tomosynthesis contribute to cancer visualization in this population  of patients? We evaluated the cancers seen in both high-risk patients, those with a >20% lifetime risk of breast cancer, and intermediate risk  patients, those with a 15-20% lifetime risk of breast cancer, for a total of 56 cancers. We found that 41% (23/56) cancers were better seen on tomosynthesis and 4% (2/56) were only seen on tomosynthesis. The majority of the cancers seen better or only on tomosynthesis  presented as masses rather than as calcifications alone which were better seen on 2D mammography. (more…)

Dr. Li: The main finding is that intake marine n-3 polyunsaturated fatty acids (n-3 PUFAs) from both fish and fish oil lower the risk of breast cancer. Women with a high intake of marine n-3 PUFAs had a 14-percent reduction in risk of breast cancer compared with those who had a low intake. Every 0.1 g increase in marine n-3 PUFA per day was linked to a five-percent reduction in breast cancer risk. (more…)

DR. RAUL ZAMORA-ROS, PhD. POSDOCTORAL FELLOW UNIT OF NUTRITION, ENVIRONMENT AND CANCER CATALAN INSTITUTE OF ONCOLOGY (ICO) – BELLVITGE BIOMEDICAL RESEARCH INSTITUTE (IDIBELL) BARCELONA, SPAIN MedicalResearch.com: What are the main findings of the study? Dr. Zamora-Ros:  Our study shows that diets rich on flavonoids (polyphenols ubiquitously distributed in the plant kingdom, such as in fruit, vegetables, tea, wine and chocolate), particularly flavonols, are associated with less esophageal cancer risk, especially in current smokers. Tobacco smoking causes oxidative stress, and both oxidative stress and smoking tobacco are related to increased esophageal cancer risk. Therefore, our data suggest that the possible protective mechanism of dietary flavonoids may be related to their antioxidant properties, which may not be attributed to the direct antioxidant action, but to the ability to modulate antioxidant enzymatic pathways.

MedicalResearch.com eInterview with Ronald Levy, M.D. Professor and Chief Division of Oncology Stanford University, 269 Campus Drive Stanford, California 94305, USA MedicalResearch.com: What are the main findings of the study? Dr. Levy: Injection of antibodies that deplete Treg cells directly into a tumor can evoke an immune response that cures  the animal of distant, untreated tumors. This effect eliminates cancer even in the brain. The dose of antibodies locally injected can be as low as 1/100 the dose used for systemic injection and therefore should avoid the usual autoimmune side effects of these antibodies. The antibodies used are directed against CTLA4 and OX40 antigens. (more…)

Daskivich, MD Robert Wood Johnson Foundation Clinical Scholars® University of California Los Angeles Division of General Internal Medicine and Health Services Research 10940 Wilshire Blvd, 7th Floor Suite 710, Room 721 Los Angeles, California 90024 MedicalResearch.com: What are the main findings of the study?  Were any of the findings unexpected? Dr. Daskivich:  We found that age and a simple count of comorbidities were strongly predictive of likelihood of dying of causes other than prostate cancer.  When we put numbers to it, it was surprising how often older men with multiple comorbidities were dying of something else than their prostate cancer within 14 years of diagnosis.  For example, a 75-year old man with 3 or more comorbidities—diabetes, high blood pressure, and history of heart attack—had a probability of death from something other than CaP of 71% at 10 years.  For a 71-year old man with 3 or more comorbidities, the probability was 60%.  We compared that to the amount of time they were dying of prostate cancer, which was 3% for low-risk disease and 7% for intermediate-risk disease.

MedicalResearch.com Authors’ Interview: Sophie Rousseaux and Saadi Khochbin INSERM, U823; Université Joseph Fourier, Grenoble 1; Institut Albert Bonniot, Grenoble F-38700, France. MedicalResearch.com: What are the main findings of the study? Answer: We first discovered that all cancer cells lose the ability to maintain gene silencing and therefore activate genes that should normally remain silent. Although present in all cells, some genes are normally expressed (or “active”) only in one cell type. For example, normal lung cells do not express genes that are only active in germ cells (i. e., cells that will become spermatozoa), but lung cancerous cells activate some of these germ cells-specific genes. In this work we designed a specific approach to detect these aberrant gene expressions and found that they occur in all cancers of all origins. We then decided to exploit this phenomenon to help the detection of cancers and predict their evolution. For this purpose, we chose to focus on lung cancer to establish “a proof of principle”. We found that, among all the genes wrongly expressed in the tumour cells, the activation of 26 of them enabled us to identify the most aggressive lung cancers. Compared with the existing information currently available for doctors (i.e.; tumour size, its pathological subtype…), our approach brings much more precision in predicting the evolution of the tumours and the prognosis of the patients.

MedicalResearch.com eInterview with Dr. Waël C. Hanna University of Toronto departments of Thoracic Surgery and Diagnostic Radiology, MedicalResearch.com: What are the main findings of the study? Dr. Hanna: By using Minimal Dose CT Scan (MnDCT) for surveillance of patients after lung cancer resection, we can detect 94.2% of recurrent or new lung cancer in this patient population. When we use chest x-ray (CXR) to conduct surveillance on the same cohort of patients, we can only detect 21.1% of new or recurrent lung cancer cases. Therefore, while MnDCT scan subjects the patient to a similar effective dose of radiation as CXR (0.2 mSV vs. 0.16 mSv), it is a vastly superior test for follow-up of this high risk population. More importantly, when we use MnDCT for surveillance, we can detect new or recurrent lung cancer at the asymptomatic locoregional stage in 78% of patients, and there quarters of those patients are candidates for further treatment in the form of surgery or radiation. In the patients who were treated, median survival was 69 months after initial operation, versus 25 months in those who received no treatment. (more…)

MedicalResearch.com eInterview with Christian Löw, Ph.D. Department of Medical Biochemistry and Biophysics Karolinska Institutet SE-171 77 Stockholm Sweden MedicalResearch.com: What are the main findings of the study? Dr. Löw: In order to grow, cells need fuels such as sugars. Specialized proteins that reside in the cell envelope transport these nutrients into the cell; XylE is a bacterial transport protein that is highly similar to members of the human GLUT transporters. Our study describes for the first time the mechanistic details of how cells import sugars by resolving the different steps of the transport cycle at almost atomic resolution. Tumors are especially dependent on the uptake of sugars and other nutrients via these transporter systems in order to be able to grow rapidly. A possible strategy for cancer treatment therefore would be to block these transporters in the cell membrane, thus starving out and killing the cancer cells. Our structures can be used for initial structure based drug design studies to develop efficient and specific inhibitors against members of the GLUT family. We believe that our detailed mechanistic insights could become the basis for new strategies to fight cancer cells. Specialized proteins that reside in the cell envelope transport these nutrients into the cell; XylE is a bacterial transport protein that is highly similar to members of the human GLUT transporters (more…)

Dr. Koroukian: Among individuals who died of cancer, those with mental illness (MI) died an average of 10 years earlier than those without MI. Overall, there was excess mortality from cancer associated with having mental illness in all the race/sex strata: SMR, 2.16 (95% CI, 1.85-2.50) for black men; 2.63 (2.31-2.98) for black women; 3.89 (3.61-4.19) for nonblack men; and 3.34 (3.13-3.57) for nonblack women. We note statistically significant higher SMRs for every anatomic cancer site in nonblack men and women and for most cancer sites in black men and women. (more…)

MedicalResearch.com eInterview with Andrew Weickhardt, MBBS, DMedSc, FRACP MedicalResearch.com: What are the main findings of the study? Dr. Weickhardt: The study was hoping to confirm our earlier published observation that crizotinib use led to low testosterone in male patients. The earlier study was based on our observation of symptoms of low testosterone in some patients treated with the drug, and had suggested strongly that crizotinib led to rapid decrease in testosterone levels, however this was based only on a single center's patients, and only 19 patients. We hoped to do this by surveying a larger population of crizotinib treated patients across multiple institutions. We serially measured several relevant hormones. (more…)

MedicalResearch.com eInterview with Vincent Yi-Fong Su MD Department of Chest Medicine, Taipei Veterans General Hospital, Taipei, Taiwan MedicalResearch.com: What are the main findings of the study? Answer: Amiodarone, one of the most widely used medications to treat arrhythmias may increase the risk of developing cancer, especially in men and people exposed to high amounts of the drug. That is the conclusion of a new retrospective study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. Patients who were male or who received high cumulative daily doses of amiodarone within the first year had an increased risk of developing cancer. Those with both factors were 46 percent more likely to develop cancer than those with neither factor. (more…)

Prof. Domany: The findings are two-fold: methodological and clinical.  A novel method was introduced for personalized analysis of cancer, and was applied on large colon cancer and glioblastoma datasets. The method uses high throughput (gene expression) data to infer a pathway deregulation score (PDS) for individual tumors, for hundreds of pathways and biological processes. The method is knowledge-based in that it uses well known information about the assignment of genes to biologically relevant pathways. No detailed knowledge of the underlying networks of interactions and activations is necessary. Each tumor is represented by a few hundred of these PDSs, and further analysis uses this representation.

MedicalResearch.com Author Interview: Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810.Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810. MedicalResearch.com: What are the main findings of the study? Dr. Branstetter: This study demonstrated that the time to the first cigarette of the day after waking is associated with increased levels of a NNAL, a metabolite of a powerful tobacco-specific carcinogen, NNK -- even after controlling for the total number of cigarettes smoked per day. For years, the time to the first cigarette of the day after waking was one of several questions assessing nicotine dependence on the Fagerstrom Test for Nicotine Dependence (FTND), the gold standard questionnaire int he field. Over time, it was found that much of the predictive validity of the FTND was due to the time to first cigarette item. Researchers have found that single time to first cigarette item was highly correlated with other measures of nicotine dependence, and was predictive of more difficulty quitting smoking and increased intake of nicotine. Our current study demonstrates that this behavioral measure, is predictive of exposure to the cancer-causing components of cigarettes, regardless of the total number of cigarettes smoked per day. The results suggest that researchers, clinicians and smokers can assess the level of nicotine dependence and potential cancer risk by looking at the time to the first cigarette of the day after waking.
