MedicalResearch.com Interview with: Dr. Mathew Galsky MD Associate Professor, Medicine, Hematology and Medical Oncology Assistant Professor, Urology Director, Genitourinary Medical Oncology The Tisch Cancer Institute Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Since the development of combination cisplatin-based chemotherapy for the treatment of metastatic bladder (urothelial) cancer several decades ago, there have been few advances in the treatment of this disease. Further, until recently, there had been no global standard treatment options for patients with metastatic urothelial cancer progressing despite platinum-based chemotherapy. Several lines of evidence suggest that urothelial cancer may be sensitive to immunotherapeutic treatment strategies. Recently, in a phase I/II study published by Sharma and colleagues in Lancet Oncology, the anti-PD-1 antibody Nivolumab demonstrated a durable objective response rate of 24% in patients with metastatic urothelial cancer progressing despite platinum-based chemotherapy. To confirm to antitumor effects of Nivolumab in this patient population, we conducted a large global multicenter single-arm phase II study (more…)

MedicalResearch.com Interview with: Dr. Sham Mailankody, MBBS Memorial Sloan Kettering Cancer Center MedicalResearch.com: What is the background for this study? Response: The high price of older drugs has been increasingly criticized in part because of recent dramatic price hikes. There are some well known examples like pyrimethamine and more recently EpiPen. Whether and to what degree examples like pyrimethamine represent a common problem or exceptional cases remains unknown. Using Medicare data available for Part B, we sought to analyze the change in average sales price of cancer drugs between January 2010 and January 2015, and whether older drugs were more likely to undergo price increases than newer drugs.

MedicalResearch.com Interview with: Riccardo Taulli, PhD Assistant Professor of Biochemistry Dept. of Oncology, University of Turin Via Santena 5, 10126 Torino, Italy MedicalResearch.com: What is the background for this study? Response: Rhabdomyosarcoma is a muscle-derived pediatric cancer for which therapeutic options have not improved significantly over the past decades, especially for its metastatic form. MicroRNAs are small regulatory molecules that control gene expression at the post-transcriptional level, fine tuning a wide number of cellular mechanisms, processes and behaviors. In our work, we underwent a large microRNA isolation and sequencing effort using human samples of the three major rhabdomyosarcoma subtypes, along with cell lines and normal muscle, to identify novel molecular circuits with therapeutic potential.

MedicalResearch.com Interview with: Eric Jacobs, PHD Strategic Director, Pharmacoepidemiology American Cancer Society, Inc. 250 Williams St. Atlanta, GA 30303 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Vasectomy is a common, inexpensive, and very effective method of long-term birth control. However, in 2014, an analysis from a large epidemiologic cohort study, the Health Professionals Follow-Up Study, found that vasectomy was associated with about 10% higher overall risk of prostate cancer and about 20% higher risk of fatal prostate cancer. Together with other researchers at the American Cancer Society, I analyzed the association between vasectomy and fatal prostate cancer among more than 363,000 men in the Cancer Prevention Study II (CPS-II) cohort, age 40 and older, who were followed for up to 30 years. This is the largest prospective analysis of vasectomy and fatal prostate cancer to date. We also examined vasectomy and prostate cancer in a subset of about 66,000 CPS-II study participants who were followed for new diagnoses of prostate cancer. We found no link between having had a vasectomy and risk of either developing or dying from prostate cancer. (more…)

MedicalResearch.com Interview with: Paola Scaffidi, PhD Group Leader Cancer Epigenetics Laboratory The Francis Crick Institute London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Every cancer is different, but even within the same tumor cells are highly diverse, and only some of them are truly immortal and drive tumor growth. This is quite surprising if we think that cancer arises from one cell that keeps replicating itself. So why are some cancer cells more dangerous than others? And why do some cells "get tired" along the way and, at some point, stop dividing? In our study we describe one cellular mechanism that provides some answers to these questions. We have found that to be able to divide indefinitely, cancer cells have to strongly reduce the levels of a nuclear protein called histone H1.0. This is needed to allow activation of many genes important for cancer cell proliferation, which otherwise would be somehow "hidden" within the cell nucleus. Importantly, though, while tumors grow, some cells raise back the levels of H1.0, which hides these genes again and makes the cells stop proliferating. So the end result is that within the same tumor we have a mix of cells, some which keep these important genes on, while others switch them off and, as a consequence, lose their ability to divide, and differentiate into a more mature state.

MedicalResearch.com Interview with: Adam Brufsky, MD, PhD, FACP Medical Director of the Women's Cancer Center University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings?
  • The Make Your Dialogue Count survey was conducted by Harris Poll on behalf of Novartis between June 20 and August 22, 2014. A total of 359 surveys were collected among women 21 years+ living with advanced breast cancer in addition to 234 caregivers of women with advanced breast cancer and 252 licensed oncologists who treat at least five advanced breast cancer patients per month within the United States. Novartis conducted the survey with guidance from oncologists, patient advocacy experts and a psychologist to better understand the dialogue around treatment goals and decisions that takes place among advanced breast cancer patients, caregivers and oncologists.
  • Main survey findings show communication gaps exist in discussions between patients and oncologists, particularly around treatment plans and goals.
  • 89% of patients and 76% of oncologists said that it’s important or very important to discuss long-term treatment plans beyond the current recommended treatment at their initial advanced breast cancer diagnosis. Yet, 43% of patients reported that this did not take place.
  • 70% of patients and 65% of oncologists said that it’s important or very important to refer patients to support services at their initial advanced breast cancer diagnosis. Yet, only 36% of patients reported that this was something their doctor did.
  • 23% of oncologists said that at times their emotions have kept them from sharing certain information with their advanced breast cancer patients, and 27% of oncologists said that, in certain situations, they do not discuss with patients the fact that advanced breast cancer is incurable.

MedicalResearch.com Interview with: Darren R. Feldman, MD Medical Oncologist Memorial Sloan Kettering Cancer Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is limited knowledge as to why a minority of patients with advanced germ cell tumors are resistant to chemotherapy while the majority achieve complete responses. Patients with cisplatin-resistant disease require intensive salvage treatment and are at high risk of dying from their disease. We sought to determine whether certain genomic alterations within tumors might be associated with cisplatin-resistance in GCT. We also wanted to identify the spectrum of genomic alterations in this population which might represent novel targets for existing or new drug development in this disease. (more…)
Author Interviews, Dermatology, Journal Clinical Oncology, Melanoma / 21.09.2016

MedicalResearch.com Interview with: Reza Ghiasvand, PhD Postdoctoral fellow, Department of Biostatistics, Faculty of Medicine, University of Oslo. Oslo, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: To date, findings from studies have been inconsistent. Some studies found a decreased risk of melanoma among sunscreen users, while others found no association or a higher risk of melanoma among sunscreen users. Several studies found that many sunscreen users do not apply sunscreens properly and do not reapply as recommended and stay longer in the sun after using sunscreen and as a result get sunburn and increase their risk of skin cancer. Our findings suggest higher UV exposure among sunscreen users compared to nonusers. However, those who used sunscreen with high SPF had 33% lower risk of melanoma compared to users of low SPF sunscreens. (more…)

MedicalResearch.com Interview with: Larissa A. Meyer, MD MPH F.A.C.O.G. Assistant Professor Dept of Gynecologic Oncology and Reproductive Medicine Houston, TX 77030-1362 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the completion of two randomized controlled trials, controversy regarding the optimal approach for the treatment of advanced ovarian cancer remains. Our observational study highlights the importance of thoughtful selection of individuals for primary cytoreductive surgery for advanced ovarian cancer. Our results suggest that primary cytoreductive surgery may improve survival for patients with stage IIIC ovarian cancer who are likely to achieve an optimal cytoreduction, while neoadjuvant chemotherapy may be the preferred option for many women with stage IV ovarian cancer.

MedicalResearch.com Interview with: Pooja Rao, MD, MSCE Assistant Professor Division of Pediatric Hematology/Oncology Milton S. Hershey Medical Center Penn State College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although many chemotherapy drugs can cause birth defects, no standardized guidelines exist for pregnancy screening in adolescent female patients with cancer. Additionally, little is known about how often they are screened prior to receiving treatment. Our study found that adolescent girls are not adequately screened for pregnancy prior to receiving chemotherapy or CT scans that could potentially harm a developing fetus. Adolescents with acute lymphoblastic leukemia, the most common childhood cancer, had the lowest pregnancy screening rates of the patients studied. (more…)

MedicalResearch.com Interview with: Chih-Hsin Yang MD PhD Department of Oncology National Taiwan University Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: LUX-Lung 3 and LUX-Lung 6 are multicenter, randomized, open-label, Phase III trials of afatinib versus chemotherapy (pemetrexed / cisplatin and gemcitabine / cisplatin, respectively) as first-line treatment for patients with EGFR mutation-positive, advanced and metastatic non-small-cell lung cancer (NSCLC). Both trials met their primary endpoint of PFS with afatinib significantly delaying tumor growth when compared to standard chemotherapy. A post-hoc analysis of the studies was conducted to look at the incidence and severity of common adverse events (AEs) before and after afatinib dose reduction and the PFS was compared between patients who dose reduced within the first 6 months of treatment and those who did not. The results showed dose reductions were associated with decreases in the incidence and severity of treatment-related AEs, while median progression-free survival (PFS) was similar in patients who dose-reduced within the first six months of treatment versus those who did not (LUX-Lung 3, 11.3 vs 11 months; LUX-Lung 6, 12.3 vs 11 months).

Author Interviews, Nature, Pancreatic / 09.09.2016

MedicalResearch.com Interview with: Armando E. del Río Hernández, PhD European Research Council Fellow Head, Cellular and Molecular Biomechanics Laboratory http://biomechanicalregulation-lab.org/ Senior Lecturer, Department of Bioengineering Imperial College London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pancreatic cancer is an extremely aggressive disease with an unacceptably low survival rate that has not changed during the last 40 years despite significant efforts aimed at developing therapies against cancer cells. Pancreatic cancer is characterised by an extensive desmoplasia, which forms the majority of the tissue around the tumour. This desmoplastic tissue is known to help the tumour to grow and metastasize, and hinders drug delivery. We have focused our efforts on understanding how pancreatic stellate cells (PSCs), which are the key effectors that orchestrate the desmoplastic reaction in pancreatic cancer, can promote tumour progression. PSCs in healthy pancreas have abundant vitamin A storage in their cytoplasm and exist in a quiescent state that guarantees a balanced tissue homeostasis. In pancreatic cancer, loss of this balance activates PSCs, which lose the vitamin A content and remodel the surrounding tissue to make it favourable for cancer cell invasion. We found that treating PSCs which ATRA (All trans-retinoic acid), the active metabolite of vitamin A mechanically reprograms PSCs to promote quiescence in vitro. Quiescent PSCs are unable to remodel the microenvironment to allow pancreatic cancer cell invasion. To get more information about our findings please find the article in the open access journal Nature Communications:http://www.nature.com/articles/ncomms12630 (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Colon Cancer, End of Life Care, Lung Cancer / 09.09.2016

MedicalResearch.com Interview with: Joseph A. Greer, Ph.D. Program Director, Center for Psychiatric Oncology & Behavioral Sciences Associate Director, Cancer Outcomes Research Program, Massachusetts General Hospital Cancer Center Yawkey Center, Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many patients with advanced cancer have a high symptom burden, increased depression symptoms, misperceptions about their prognosis, and difficulties in making decisions about care at the end of life. To address these challenges and improve care for this vulnerable population, our research team initially conducted a small, single-group pilot study of early palliative care integrated with standard oncology care for patients with advanced lung cancer. This study showed that the model of integrated care was feasible and acceptable to patients and their families. Specifically, the majority of patients in the study were able to meet with a palliative care clinician at least monthly from the time of diagnosis of metastatic lung cancer, in order to receive help with managing symptoms as well as support for coping with the disease and making decisions about treatment. We then conducted a follow-up randomized controlled trial of early, integrated palliative care in a sample of approximately 150 patients with metastatic non-small cell lung cancer. This study was published in the New England Journal of Medicine in 2010 and showed that those patients who received early palliative care reported significantly improved quality of life, mood, prognostic awareness, and end-of-life care compared to those who received standard oncology care alone. To confirm the findings of our prior research and to determine whether the benefits of early integrated palliative care would apply to a larger sample of patients with diverse malignancies, we recently completed another randomized trial of this same model of care in a sample of 350 patients with incurable lung and gastrointestinal cancers. In this trial, we observed that patients who received the early palliative care intervention reported higher quality of life and improved mood by 24 weeks but not at the primary end-point of 12 weeks. Our team was surprised to find that the trajectory of quality of life and depression symptoms over time was different for individuals with incurable lung versus gastrointestinal cancers in this study. As expected, the palliative care intervention positively buffered the decline in quality of life by 12 weeks for patients with incurable lung cancer, as we had seen in our prior trial. However, the group of patients with gastrointestinal cancers reported an improvement in their quality of life by the 12-week time point regardless of whether they received the palliative care intervention. We are still exploring possible reasons for this difference, such as whether changes in cancer therapy may have reduced symptoms and improved quality of life in the group of patients with gastrointestinal cancer. In addition, we were pleased to learn that the early integrated palliative care intervention led to improvements in how patients cope with their illness. For example, compared to patients in the usual oncology care group, those who received early, integrated palliative care were more likely to learn ways to accept their diagnosis and to take positive actions to make their lives better. So, in addition to treating patients’ symptoms, the palliative care clinicians in this study were bolstering people’s adaptive coping skills. (more…)
Author Interviews, Cancer Research / 09.09.2016

MedicalResearch.com Interview with: Professor David Adelson PhD Chair of Bioinformatics The University of Adelaide MedicalResearch.com: What is the background for this study? What are the main findings? Response: Chinese Medicine has been used for thousands of years to treat a number of diseases, but with few exceptions, has not been linked to specific molecular mechanisms that might explain its mode of action. This is because the Chinese Medicine formulations are often combinations of multiple plant extracts and are thus complex molecular mixtures. Fractionation of these extracts to test individual components often demonstrates low or no activity for individual components of these mixtures. We decided to use a Systems Biology approach to investigate a well characterized, injectable extract from two plants that has been commonly used in conjunction with Western chemotherapy to treat cancer patients in China. We do not fractionate the mixture, but test it “as is” in order to determine the molecular consequences of the complex mixture. We limited this study to a specific breast cancer cell line (MCF-7) in order to determine if this preparation, Compound Kushen Injection (CKI), can directly affect cancer cells. We found that CKI can kill MCF-7 cells and can also alter gene expression patterns associated with cell cycle control and cell death. The gene expression networks/pathways altered by CKI are similar to those altered by the Western chemotherapeutic drug 5-Fluorouracil (5FU), but the specific genes in those pathways with expression altered by CKI are often different to those affected by 5FU.

MedicalResearch.com Interview with: Erin Kent, PhD, MS Program Director Outcomes Research Branch of the Healthcare Delivery Research Program National Cancer Institute MedicalResearch.com: What is the background for this study? Response: Informal or family caregivers assist loved ones by providing care which is typically uncompensated, takes place typically at home, and often involves significant efforts for an extended period of time. Caregiving can require the performance of demanding tasks, which include managing symptom burden, monitoring for side effects from treatment, coordinating care, administering medication, and managing a care recipient’s financial and social obligations. In addition, there are many unique aspects of cancer that can place unique demands on caregivers, including sometimes a rapid deterioration of health, the receipt of multi-modal therapy (eg. surgery, chemotherapy, and radiation), and the possibility of cancer recurrence.

Author Interviews, Breast Cancer, JAMA / 08.09.2016

MedicalResearch.com Interview with: Conny Vrieling, M.D., Ph.D. Radiation Oncologist Clinique des Grangettes Geneva MedicalResearch.com: What is the background for this study? Response: In the early ’90s, the EORTC (European Organisation for Research and Treatment of Cancer) ran the “boost no-boost” trial, randomizing 5569 early-stage breast cancer patients, treated with breast-conserving surgery and whole-breast irradiation, between no boost and a 16-Gy boost. A third of the patients were included in a central pathology review. The 10-year follow-up results of this subpopulation showed that young age and high-grade invasive carcinoma were the most important risk factors for ipsilateral breast tumor recurrence (IBTR). In this study, we re-analyzed with long-term follow-up the pathological prognostic factors related to IBTR, with a special focus on the evolution of these effects over time. (more…)

Lipshultz, MD, FAAP, FAHA Schotanus Family Endowed Chair of Pediatrics / Carman and Ann Adams Endowed Chair in Pediatric Research / Professor, Carman and Ann Adams Department of Pediatrics / Professor of Medicine (Cardiology), Oncology, Obstetrics/Gynecology, Molecular Biology/Genetics, Family Medicine/Public Health Sciences, & Pharmacology /Professor in the Center for Molecular Medicine and Genetics Wayne State University School of Medicine President, University Pediatricians & Interim Director, Children’s Research Center of Michigan Pediatrician-in-Chief, Children’s Hospital of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Surviving childhood cancer has dramatically and increasing improved to the point where more than 80% will achieve a 5-year event free survival. Many of these survivors look forward to decades of active productive life. More than half of these survivors have been treated with therapies know to be associated with late cardiotoxicity that can be pervasive, persistent, and progressive and associated with cardiovascular morbidity and mortality. In this article we review both the course and prevention of this cardiotoxicity. We focus in part on anthracycline chemotherapy that is widely used and known to be cardiotoxicity. We further review studies we and others have conducted to examine the effectiveness of dexrazoxane, an iron chelator, that when given before each anthracycline dose results in anthracycline cardioprotection for long term survivors. In some reported studies this has allowed for higher cumulative anthracycline doses to be safely given. In other cases this has allowed for simultaneously being able to safely treat children with malignancies that would be refractory to conventional therapy more potent therapies that would normally have additive cardiotoxicity.

MedicalResearch.com Interview with:  

Ilaria Stura PhD

Università degli Studi di Torino Turin, Piedmont, Italy

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

Response: Man has always tried to predict the future, especially to prevent catastrophes, diseases and death. In this case, we want to prevent the ‘personal catastrophe’, i.e. the spread of the disease (recurrence of prostate cancer) in the patient. Our work therefore belongs to the so-called ‘personalized medicine’, a very important and innovative clinical approach.

In particular this study may potentially improve the quality of life of the patients and help the clinicians, since it could give valuable information to the urologist, for example reporting that the growth velocity of the tumor is increasing and that a relapse is expected within few months. With this information, the clinician could chose the best therapy for the patient (e.g. hormone or radio therapy) in order to stop the spread of the disease or, conversely, the use of drugs can be delayed if not necessary. Obviously clinicians already try to do this, based on their experience, but our method provides further confidence in their 'investigation' work, since the algorithm is validated on data coming from a database much larger than his/her personal experience.

MedicalResearch.com Interview with: Adam G Alani, PhD Associate Professor of Pharmaceutical Sciences Department of Pharmaceutical Sciences College of Pharmacy Oregon State University-Oregon Health & Science University Affiliate Assistant Professor Department of Biomedical Engineering School of Medicine at Oregon Health & Science University Oregon State University-Portland Campus at OHSU Portland Oregon MedicalResearch.com: What is the background for this study? Response: Current chemotherapeutic regimens while effective are difficult for patients and affect their quality of life. Our research tackles this issue by designing a nanotherapy that can deliver multiple chemotherapeutic agents by targeting the entire tumor microenvironment and not just the cancer cells and by reducing drug resistance. This, then is intended to simplify the treatment regimen, reduce drug related side effects and extends the life of the drugs by preventing resistance should the patient need it in the future. Thus, the ultimate underlying goal is to improve the patient’s quality of life by not just maximizing the drug’s efficacy but also trying to decrease its impact on the overall lifestyle of the individual.

Accidents & Violence, Author Interviews, BMJ, Cancer Research, Karolinski Institute / 02.09.2016

MedicalResearch.com Interview with: Qing Shen, PhD student Department of Medical Epidemiology and Biostatistics Karolinska Institutet MedicalResearch.com: What is the background for this study? Response: Injury, either iatrogenic (for example, complications from medical procedures and drug treatment) or non-iatrogenic (for instance, suicidal behavior and accidents), is one of the leading causes of non-cancer mortality for patients diagnosed with cancer. Iatrogenic injuries are common in those with cancer and have been shown to increase mortality in some cancer patients. Increased risks of suicide and accidental death after diagnosis have been reported, and the diagnostic process of cancer has been recognized highly stressful. It is, however, unknown whether the risk of injuries is also increased during the time period before receiving the diagnosis. Actually confirming a diagnosis can often be difficult due to patients sometimes concealing information. This is why Motivational Interviewing is important. Anyway, we analysed the risks of injuries during the weeks before and after diagnosis using a nationwide study sample in Sweden. (more…)
Author Interviews, Cocaine / 01.09.2016

MedicalResearch.com Interview with: Dr Stefania Fasano Cardiff University MedicalResearch.com: What is the background for this study? Response: Exposure to drugs of abuse such as cocaine produces intense and long-lasting memories that are critical in the transition from recreational drug-taking to uncontrolled drug use. In the brain, addictive drugs usurp cellular circuits and signalling molecules involved in normal memory processes; hence, these drug-related memories resist extinction and contribute to high rates of relapse. Despite almost five decades of experimental research, there are currently no approved medications for cocaine dependence. (more…)

MedicalResearch.com Interview with: Dr. Manel Esteller Director of the Epigenetics and Cancer Biology Program (PEBC) Bellvitge Biomedical Research Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cancer of Unknown Primary (CUP) occurs when the patient is diagnosed with a metastasis but the primary tumor is not found. It accounts for around 5-10% of tumors around the world and the survival is very poor. Until now, only in 25% of cases the primary site was identified after diagnosis pipeline. We are showing herein that the use of epigenetic profiling, based in the determination of the chemical marks occurring in DNA that are tumor-type specific, reaches a diagnoses of 87% of cases.

MedicalResearch.com Interview with: Dr Charles Akle, Chairman and Linda Summerton, CEO Immodulon Therapeutics Short Hills, NJ 07078 and London, UKDr Charles Akle, Chairman and Dr. Linda Summerton, CEO Immodulon Therapeutics Short Hills, NJ 07078 and London, UK MedicalResearch.com: What is the background for Immodulon? Would you tell us a little about Dr. Charles Akle? Response: Immodulon was established in November 2007. The founder and Chairman, Dr Charles Akle, was a Harley Street surgeon and pioneer of keyhole surgery who established Immodulon with the financial support of a former patient. His interest in immunology led him to the potential of cancer immunotherapy long before the term “immuno-oncology” was coined and when skepticism, rather than optimism was the norm. His ambition from the start was to develop an affordable immunotherapy treatment that would transform the way that cancer is treated in the world today. Since then, Immodulon has become a leading, independent biopharmaceutical company with one of the longest running research projects into how to harness the power of the immune system in treating cancer. It also has its own R&D and manufacturing capability in Lyon, France. The wider Immodulon senior team has extensive experience of bringing drugs to market and includes Dr James Shannon and Dr Jean Pierre Bizzari. (more…)

MedicalResearch.com Interview with: Leni van Doorn, MSc Department of Medical Oncology Erasmus MC Cancer Institute Rotterdam, the Netherlands MedicalResearch.com: What is the background for this study? Response: The common cancer treatment capecitabine, a regular treatment for patients mostly diagnosed with breast-, colon- or gastic cancer, induces hand foot syndrome (HFS). HFS is a cutaneous condition that may lead to red palms and blisters in approximately 50% to 60% of the patients and is believed to result in the loss of fingerprints. This fingerprint loss has been described sporadically in the literature. The main aim of our prospective study was to have a closer look of the association between  hand foot syndrome and the loss of fingerprints. (more…)

MedicalResearch.com Interview with: Y. Nancy You, MD, MHSc Associate Professor Section of Colorectal Surgery Department of Surgical Oncology Medical Director Familial High-risk Gastrointestinal Cancer Clinic University of Texas MD Anderson Cancer Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the progress in the treatment of many cancers, colorectal cancer (CRC) remains the third most common and lethal cancer in the US. Over 130,000 people are expected to be diagnosed and over 50,000 patients will die from CRC this year. In the recent years, the most exciting development has been our understanding of the molecular complexity of CRC. Currently, four major molecular subtypes of colorectal cancer are recognized. Our study focuses on the Consensus Molecular Subtype 1, which accounts for up to 15% of CRCs, and is characterized by a deficiency in DNA mismatch repair (dMMR), a high level of mutations (i.e. hypermutated), by instability in parts of the genome called microsatellites, and by strong immune activation. Prior to our study, patients with rectal cancer that belong to this molecular subtype have represented an unknown, in terms of their prognosis, and how the tumors respond to current treatments. More importantly, this molecular subtype harbor a genetic condition that can be transmitted within the family called “Lynch Syndrome”. So we designed our study to fill these gaps in our understanding that exist in this subtype of CRCs and to highlight key clinical care issues related to the caring for patients with a genetic syndrome. The main findings are that rectal cancers belonging to this molecular subtype have favorable prognosis, respond well to standard chemoradiation, and are linked to Lynch Syndrome and should be treated at centers with expertise in hereditary cancer syndromes.

Author Interviews, Brigham & Women's - Harvard, Cancer Research, Cost of Health Care / 08.08.2016

MedicalResearch.com Interview with: Sarah C. Markt, ScD, MPH Research Associate Harvard T.H. Chan School of Public Health | Department of Epidemiology Boston, MA 02115 MedicalResearch.com: What is the background for this study? Response: Age is associated with insurance status, with the greatest proportion of uninsured between the ages of 20 to 34 years. For testicular cancer this is important because the median age of diagnosis is 33 years and the majority of the cases are diagnosed between then ages of 20 and 44 years. Previous studies have shown that people with cancer who are uninsured are more likely to present with worse disease, less likely to receive treatment, and are more likely to die of their disease, compared with those who have private insurance. Furthermore, the associations between Medicaid coverage and cancer outcomes have been conflicting. (more…)
