MedicalResearch.com Interview with: Giampaolo Greco PhD MPH Assistant Professor Department of Population Health Science and Policy Icahn School of Medicine  at Mount Sinai MedicalResearch.com: What is the background for this study? Response: The motivation for our study was to understand why mortality rate from breast cancer is much higher in African American women than in White women, despite the fact that these groups have similar incidence rate of breast cancer. Metabolic syndrome, a cluster of metabolic abnormalities that includes abdominal obesity, hypertension, hyperglycemia and dyslipidemia, is more prevalent among African American women and may be a risk factor for breast cancer. Subjective social status (SSS) is the perception of individuals of their own ranking in the social hierarchy and complements other parameters of socioeconomic status, such as income and education, that are considered more objective. Socioeconomic status is associated with cardiovascular and mental health. Although objective measures of social status are associated with worse breast cancer outcomes, the relationship of SSS to breast cancer is uncertain. (more…)
Author Interviews, Brigham & Women's - Harvard, Journal Clinical Oncology, Prostate Cancer, Radiation Therapy / 04.06.2021

MedicalResearch.com Interview with: Anthony D'Amico, MD, PhD Professor and Chief of Genitourinary Radiation Oncology Brigham and Women's Hospital and Dana-Farber Cancer Institute MedicalResearch.com: What is the background for this study? Response: 3 randomized trials published in Sept, 2020 in the Lancet and Lancet Oncology concluded that delivering radiation therapy (RT) after surgery for prostate cancer   when the PSA rises signaling recurrence (i.e. early salvage RT) as opposed to when the PSA is undetectable (i.e. adjuvant RT) did not compromise subsequent cancer progression. However these trials may have missed the benefit of adjuvant RT because a minority of men (9 to 17% of the study cohorts) were found to have adverse factors at prostatectomy which are associated with cancer progression and death from prostate cancer. Specifically, men with adverse pathology at prostatectomy comprise the vast majority of men who go on to die from prostate cancer and therefore have the most to gain from adjuvant RT. Yet, given the results of the 3 randomized trials many physicians are no longer offering adjuvant RT, even in men with adverse pathology at surgery. (more…)

MedicalResearch.com Interview with: Kristine Gade, MD Hematology/Oncology Fellow UPMC Hillman Cancer Center MedicalResearch.com: What is the background for this study? Would you briefly describe the “surprise question”?  Response:  Via Oncology Pathways, a cancer care platform used by UPMC and other institutions across the country, asks physicians to answer the surprise question – “Would I be surprised if this patient died in the next 12 months?” – whenever a new treatment plan is implemented.   This question has been widely adopted by many oncology and palliative care frameworks and has been shown to be modestly predictive of mortality in multiple studies.  We know that advanced cancer patients have a high utilization of the emergency department, even near end of life.  Our group wanted to see if we could use the results of the surprise question to easily and quickly communicate to emergency department providers the expected prognosis for our advanced cancer patients.  First, we set out to assess the surprise question’s ability to predict survival among our UPMC Hillman Cancer Center patients with select stage IV cancer diagnoses.   (more…)

MedicalResearch.com Interview with: Matthew Galsky, MD Icahn School of Medicine at Mount Sinai New York, NY MedicalResearch.com: What is the background for this study? Would you explain what is meant by switch maintenance immunotherapy? Response: For decades, platinum-based chemotherapy has been standard first-line treatment for metastatic urothelial (bladder) cancer. The standard approach to first-line chemotherapy is to administered approximately 6 cycles of treatment (in the absence of disease progression or prohibitive side effects), and then to stop treatment and monitor. Unfortunately, virtually all patients with metastatic disease will experience disease progression after stopping chemotherapy. However, we know that if we just continue the same platinum-based chemotherapy until progression of cancer (rather than stopping after ~6 cycles), the side effects continue to accumulate but the benefits plateau. Approximately 5 years ago, the first new systemic therapies were approved to treatment metastatic urothelial cancer in decades, immune checkpoint inhibitors (PD-1 or PD-L1 inhibitors). In fact, 5 PD-1/PD-L1 inhibitors have been approved by the FDA for the treatment of patients with metastatic urothelial cancer progressing despite prior platinum-based chemotherapy. Given that these drugs are non-cross resistant with chemotherapy in at least a subset of patients (i.e., they can provide benefit even when chemotherapy is no longer working), and because they are well tolerated by a large proportion of patients, a logical question is rather than waiting until cancer progresses after stopping first-line chemotherapy, what if we started immunotherapy immediately. Switch maintenance refers to switching from chemotherapy to a different class of drug (e.g., immunotherapy) and maintenance refers to trying to "maintain" the response achieved with initial chemotherapy.

MedicalResearch.com Interview with: Fangjian Guo, MD, PhD Department of Obstetrics and Gynecology Center for Interdisciplinary Research in Women’s Health University of Texas Medical Branch Galveston TX  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The identification of BRCA1/BRCA2 pathogenic variants in women susceptible to breast or ovarian cancer in the 1990s created an opportunity for targeted, individualized cancer prevention. BRCA testing in young women before cancer onset enables early detection of those with increased cancer risk and creates an opportunity to offer life-saving prophylactic procedures and medication. We used insurance claims data to assess the use of BRCA testing in unaffected young women <40 years of age between 2006 and 2017 and found that BRCA testing among cancer-free women under 40 has more than doubled in recent years. However, only about 25% of all BRCA testing done in 2017 was performed in unaffected young women under 40. (more…)

MedicalResearch.com Interview with: Dr. David Kurtz, MD/PhD, Instructor and Dr. Ash Alizadeh MD/PhD, Associate Professor Division of Oncology, Department of Medicine Stanford University Medical Center  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This work investigates the utility of circulating tumor DNA - a type of liquid biopsy - in diffuse large B-cell lymphoma, the most common blood cancer in adults. Liquid biopsies are an emerging technology to track cancers from a simple blood draw. Here, using a cohort of over 200 patients from 6 centers across North America and Europe, we asked if circulating tumor DNA could be used to detect lymphoma in patients, and more importantly, could it be used to identify responders and non-responders.  (more…)

MedicalResearch.com Interview with: David S. Siegel, MD, PhD Chief, Myeloma Division John Theurer Cancer Center Hackensack University Medical Center Hackensack, NJ 07601 MedicalResearch.com: What is the background for this study? What are the main findings?
  •  We reported results from the prospectively planned final analysis of overall survival (OS) from the Phase 3 ASPIRE trial, an international, randomized study evaluating KYPROLIS (carfilzomib) in combination with lenalidomide and dexamethasone (KRd) versus lenalidomide and dexamethasone alone (Rd) in patients with relapsed or refractory multiple myeloma following treatment with one to three prior regimens. Overall survival was a secondary endpoint in the trial.
  • Data published last week in the Journal of Clinical Oncology demonstrated that the addition of KYPROLIS to Rd reduced the risk of death by 21 percent versus Rd alone and extended OS by 7.9 months (median OS 48.3 months for KRd versus 40.4 months for Rd, HR = 0.79, 95 percent CI, 0.67 – 0.95; one-sided p=0.0045).
  • Notably, an OS improvement of 11.4 months was observed for patients at first relapse (47.3 versus 35.9 months [HR = 0.81, 95 percent CI, 0.62 – 1.06]), supporting early use of KRd.
  • The safety data from ASPIRE was consistent with the known safety profile of KYPROLIS. The most common adverse events (greater than or equal to 20 percent) in the KYPROLIS arm were diarrhea, anemia, neutropenia, fatigue, upper respiratory tract infection, pyrexia, cough, hypokalemia, thrombocytopenia, muscle spasms, pneumonia, nasopharyngitis, nausea, constipation, insomnia and bronchitis.

MedicalResearch.com Interview with: Kevin D. Courtney, M.D., Ph.D.  Assistant Professor UT Southwestern Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Clear cell renal cell carcinoma (ccRCC) is the most common form of kidney cancer. Metastatic ccRCC does not respond to traditional chemotherapy. Current standard treatments for metastatic ccRCC include drugs called vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR TKIs) that block the growth of new blood vessels that feed the cancer, as well as drugs that inhibit an enzyme called mTOR that is involved in ccRCC growth and immune therapies that rev up the body’s immune response to try to fight the cancer. Each of these treatments can have significant side effects for patients that can make them difficult to tolerate. Metastatic ccRCC is largely incurable, and we need novel and better-tolerated treatments. A central driver of ccRCC is a protein called hypoxia inducible factor 2alpha (HIF-2alpha). This protein has been very difficult to try to target with a drug. This study is the first to test a drug that targets HIF-2alpha in patients with metastatic ccRCC. The study results showed that the HIF-2alpha inhibitor, PT2385 (Peloton Therapeutics) was active in fighting metastatic ccRCC and was well-tolerated. (more…)

MedicalResearch.com Interview with: Theodore M. Brasky, PhD Research Assistant Professor The Ohio State University – James Comprehensive Cancer Center Columbus, OH 43201 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior literature has been suggestive of both a protective and harmful effect of certain B vitamins on lung cancer risk. We wanted to examine the association of intakes of vitamins B6, folic acid (B9), and B12 from supplements –which are typically taken at very high doses– and lung cancer risk in a large, prospective study of 77,000 men and women living in Washington State. The study is unique as it was designed specifically to examine associations of dietary supplements with cancer occurrence. We found that men who took high doses of vitamin B6 and B12 from individual supplements over a long period of time (meaning, doses much higher than the US RDA and much greater than what one would receive from taking a multivitamin over the long term) were at nearly 2-fold increased risk of lung cancer compared to men who did not have B6 or B12 intake from any supplemental source. This finding of increased risk appeared to be specific to men who were current smokers. Among them, long term high-dose supplementation was associated with 3-4 fold increases in lung cancer risk. We observed no increased risk for any of the supplements – B6, B12, or folic acid – with lung cancer risk in women or women who smoked. (more…)

MedicalResearch.com Interview with: Bruce G. Haffty, MD Professor and Chair, Department of Radiation Oncology Rutgers Cancer Institute of New Jersey Rutgers Robert Wood Johnson Medical School and Rutgers New Jersey Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Shorter courses of radiation for patients treated by lumpectomy are now commonly employed. For patients receiving radiation to the chest wall and lymph nodes after mastectomy, the standard 5 to 6 week course is used and shorter courses have not been adopted. We initiated this trial of a shorter course of radiation to the chest wall and lymph nodes after mastectomy to test its feasibility, safety and outcome. (more…)

MedicalResearch.com Interview with: Anne Kuijer, MD Departments of Surgery and Radiology University Medical Center Utrecht and Thijs van Dalen, PhD Department of Surgery Netherlands Cancer Institute, Amsterdam MedicalResearch.com: What is the background for this study? What are the main findings? Response: In recent years it has become evident that clinicopathological factors fail to accurately determine prognosis in hormone receptor positive early stage breast cancer patients at intermediate risk of developing metastases. Gene-expression profiles, such as the 70-gene signature (MammaPrint) are therefore increasingly used for chemotherapy decision-making. In the current multicentre study we assessed the impact of 70-gene signature use on chemotherapy decisions in these patients. We demonstrated that, without the use of the 70-gene signature, half of patients was advised chemotherapy, which reflects the current controversy regarding chemotherapy benefit. Use of the 70-gene signature changed the chemotherapy advice in half of all patients and adherence to the 70-gene signature result was high. (more…)

MedicalResearch.com Interview with: Charles N Catton, MD, FRCPC Cancer Clinical Research Unit (CCRU) Princess Margaret Cancer Centre UHN  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prostate cancer is a very common malignancy which is frequently treated with external beam radiotherapy. A typical standard treatment course can extend over 7.5-8.5 weeks. The introduction of high-precision radiotherapy treatment techniques provided the opportunity to compress treatment courses by delivering fewer, but more intensive daily treatments. The concerns with giving fewer and larger daily treatments (hypofractionation) is that toxicity may increase and that cancer control may become worse. This international randomized trial enrolled 1206 men with intermediate risk prostate cancer and compared a standard 8 week course of external beam radiation treatment with a novel hypofractionated treatment course that was given over 4 weeks. Cancer control as measured by PSA control and clinical evidence of failure, bowel and bladder toxicity and quality of life were compared. At a median follow-up of 6 years the hypofractionated regimen was found to be non-inferior to the standard regimen for cancer control. There was no difference early or late bladder toxicity between the two treatments. There was slightly worse early bowel toxicity during and immediately after treatment with the hypofractionated regimen, but there was actually slightly less long-term bowel toxicity with this same regimen.

MedicalResearch.com Interview with: Dr. Stacy Loeb MD Msc Assistant Professor of Urology and Population Health New York University Langone Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: The association between exposure to testosterone replacement therapy and prostate cancer risk is controversial.  The purpose of our study was to examine this issue using national registries from Sweden, with complete records on prescription medications and prostate cancer diagnoses.  Overall, we found no association between testosterone use and overall prostate cancer risk. There was an early increase in favorable cancers which is likely due to a detection bias, but long-term users actually had a significantly reduced risk of aggressive disease. (more…)

MedicalResearch.com Interview with: Farzin Khosrow-Khavar, M.Sc. Ph.D. Candidate Department of Epidemiology, Biostatistics and Occupational Health, McGill University Center for Clinical Epidemiology - Jewish General Hospital Montreal, QC  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies have shown an association between androgen deprivation therapy (ADT) and risk of dementia and Alzheimer’s disease. However, these studies had methodological limitations that may account for this positive association. Using appropriate study design and methodology, we found no association between androgen deprivation therapy and risk of dementia (including Alzheimer’s disease) in patients with prostate cancer. These results were consistent by cumulative duration of  androgen deprivation therapy use and by ADT modality. (more…)

MedicalResearch.com Interview with: Matthew B Yurgelun, M.D Instructor in Medicine, Harvard Medical School Dana-Farber Cancer Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: It has long been known that hereditary factors play a key role in colorectal cancer risk. It is currently well-established that approximately 3% of all colorectal cancers arise in the setting of Lynch syndrome, a relatively common inherited syndrome that markedly increases one’s lifetime risk of colorectal cancer, as well as cancers of the uterus, ovaries, stomach, small intestine, urinary tract, pancreas, and other malignancies. Current standard-of-care in the field is to test all colorectal cancer specimens for mismatch repair deficiency, which is a very reliable means of screening for Lynch syndrome. The prevalence of other hereditary syndromes among patients with colorectal cancer has not been known, though other such factors have been presumed to be quite rare. (more…)

MedicalResearch.com Interview with: Caroline Watts| Research Fellow Cancer Epidemiology and Prevention Research Sydney School of Public Health The University of Sydney  MedicalResearch.com: What is the background for this study? Response: A clinic for people at high risk of melanoma was established at the Royal Prince Alfred Hospital, Sydney in 2006 as part of a research project to look at the impact of surveillance regime which included regular full body skin examination supported by dermoscopy and total body photography at 6 monthly intervals. If a suspicious lesion was identified, the lesion was either removed or an image of the lesion was captured using digital dermoscopy and the patient returned in 3 months for review. This study aimed to estimate the costs and benefits from a health system perspective associated with specialised surveillance compared with current routine care high risk people would receive in the community.  (more…)

MedicalResearch.com Interview with: Donald R. Sullivan, M.D., M.A. Assistant Professor, Division of Pulmonary & Critical Care Medicine Oregon Health & Science University Investigator, VA Portland Health Care System MedicalResearch.com: What is the background for this study? Response: There is an inextricably link between physical and mental health, and all too often clinicians focus solely on the physical components of disease. A life-threatening diagnosis such as cancer often evokes significant psychological distress and lung cancer patients are at significantly risk. Up to 44% of lung cancer patients experience depression symptoms and 5-13% major depressive disorder, higher than most other cancers. Previous studies have demonstrated the development of depression or depression symptoms at lung cancer diagnosis can increase patient mortality, but there is a paucity of research exploring how longitudinal changes in depression symptoms impact patient outcomes.

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: 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…)

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: 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, Journal Clinical Oncology, Karolinski Institute, Leukemia / 22.06.2016

MedicalResearch.com Interview with: Hannah Bower, MSc Department of Medical Epidemiology and Biostatistics Karolinska Institutet Stockholm, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previously, if left untreated or with symptomatic treatment (up to the 1970’s), the median survival time of patients with chronic myeloid leukemia (CML) ranged between two and three years. Later, interferon alpha and allogeneic stem cell transplantation were introduced. However, improvements in survival were mainly seen in younger patients. Treatment with the tyrosine-kinase inhibitor (TKI) imatinib-mesylate (Glivec®, Gleevec®) began in Sweden in the early 2000 resulting in major survival improvements, with the exception of the old/very elderly. We investigated if these improvements continued to 2013 and if improvements are now observed in the elderly via the life expectancy and the loss in expectation of life; the latter of these quantifies the change in the life expectancy due to a diagnosis of CML. The great improvements in life expectancy, especially in the youngest patients, translate into great reductions in the loss in expectation of life. The major factor contributing to the improvement in the elderly is likely the increasing use of TKIs. (more…)

MedicalResearch.com Interview with: Valentina Petkov, MD, MPH Health Scientist/Program Officer NIH/NCI/DCCPS/Surveillance Research Program MedicalResearch.com: What is the background for this study? Dr. Petkov: The number of breast cancer diagnoses is increasing in older patients because of increasing life expectancy and changing population demographics. Despite high incidence, little is known about breast cancer biology and outcomes in patients older than 70, which are often under-represented in clinical trials. The 21-gene Oncotype DX Breast Recurrence Score assay has been used in clinical practice to predict distant recurrence risk and chemotherapy benefit in lymph node negative, hormonal receptor positive (estrogen and/or progesterone receptor positive) invasive breast cancer since 2004. The goal of our study was to evaluate the role of the 21 gene assay in older patients at population level. We used Surveillance Epidemiology and End Results (SEER) data. We included in the analysis 40,134 patients who were diagnosed with invasive breast cancer between 2004 and 2011, had negative nodes and their tumors were hormonal receptor positive and HER2 negative. Breast Cancer Specific Mortality (BCSM) was assessed at 5 years after diagnosis in patients with low risk (Recurrence Score <18), intermediate risk (Recurrence Score 18-30) and high risk (Recurrence Score >30).

MedicalResearch.com Interview with: Laura Ferris, M.D., Ph.D. Associate professor, Department of Dermatology University of Pittsburgh School of Medicine and Member of the Melanoma Program University of Pittsburgh Cancer Institute MedicalResearch.com: What is the background for this study? Dr. Ferris: Rates of melanoma, the most dangerous form of skin cancer, are on the rise, and skin cancer screenings are one of the most important steps for early detection and treatment. Typically, patients receive skin checks by setting up an appointment with a dermatologist. UPMC instituted a new screening initiative, which was modeled after a promising German program, the goal being to improve the detection of melanomas by making it easier for patients to get screened during routine office visits with their primary care physicians (PCPs). PCPs completed training on how to recognize melanomas and were asked to offer annual screening during office visits to all patients aged 35 and older. In 2014, during the first year of the program, 15 percent of the 333,788 eligible UPMC patients were screened in this fashion. (more…)

MedicalResearch.com Interview with: Giorgia Razzini, PhD Unit of Medical Oncology Civil Hospital Carpi Italy; MedicalResearch.com: What is the background for this study? What are the main findings?  Dr. Razzini: Hot flashes experienced by breast cancer patients is a significant clinical problem because there are few reliable treatment that are free of side effects and it sometime reduces compliance with endocrine therapy for prevention of cancer recurrence. Menopausal symtoms overall  heavily impact on quality of life.. Acclimat found that acupuncture combined with self-care for 3 months, is associated with significantly lower hot flash scores, compared to self-care alone ( advices on diet, physical exercise and psycoloigical support if needed). Beneficial effects persisted up to 6 months follow-up. These effects were not associated with significant adverse events. MedicalResearch.com: What should clinicians and patients take away from your report?  Dr. Razzini:  Research suggests that breast cancer women do not receive adequate care for menopausal symptoms in the clinical practice of most oncology department. Our study showed that oncologists can offer them specific integrative management strategy for menopausal symptoms including acupuncture and enhanced self-care to women with breast cancer, particularly in younger women when treatment with hormonal treatment is recommended, in order to help women to stay on their therapy and improve their quality of life.

MedicalResearch.com Interview with: Karin Ribi, PhD, MPH Head of Quality of Life Office IBCSG International Breast Cancer Study Group Bern Switzerland  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Ribi: This study investigated the quality of life (QoL) outcomes for women in the Suppression of Ovarian Function (SOFT) trial. SOFT investigated the value of adding ovarian suppression (OFS) to tamoxifen and to determine the role of the aromatase inhibitor exemestane+OFS as adjuvant (post-surgery) therapies for hormone-sensitive early breast cancer. SOFT was conducted by the International Breast Cancer Study Group (IBCSG) in over 3000 premenopausal women from more than 500 centers worldwide. The primary analysis of SOFT compared tamoxifen alone with tamoxifen+OFS in over 2000 women, and showed that adding OFS to tamoxifen did not provide a significant benefit in the overall population of premenopausal women. However, for women who were at sufficient risk for recurrence to warrant adjuvant chemotherapy and who remained premenopausal, the addition of OFS improved disease outcomes.[1] With regard to the QoL main findings, patients on tamoxifen+OFS were more affected than patients on tamoxifen alone by hot flushes at 6 and 24 months, by loss of sexual interest and sleep disturbance at 6 months, and by vaginal dryness up to 60 months. Without prior chemotherapy, patients on tamoxifen alone reported more vaginal discharge over the 5 years than patients on tamoxifen+OFS. Symptom-specific treatment differences at 6 months were less pronounced in patients with prior chemotherapy. Changes in global QoL indicators from baseline were small and similar between treatments over the whole treatment period. (more…)

MedicalResearch.com Interview with: Oleg Gluz, MD West German Study Group Breast Center Niederrhein Evangelical Hospital Bethesda Moenchengladbach, Germany MedicalResearch.com: What is the background for this study? Dr. Gluz: PlanB trial is a Phase III chemotherapy study performed in patients with clinically high risk HER2 negative breast cancer. After early amendement, Recurrence Score (Oncotype Dx) as a selection criterion for or against chemotherapy together with central pathology review were included into the study. Patients with very low RS of below 12 and up to 3 positive lymph nodes were recommended to omit chemotherapy based on the low genomic recurrence risk. Chemotherapy was omitted in about 15% of all patients. For the first time we present prospective data comparing a genomical tool (Oncotype Dx) and an independent central pathology review for grade, ER, PR, and Ki-67 from a large phase III study combined with an exploratory analysis on early relapse risk. MedicalResearch.com: What are the main findings? Dr. Gluz: The study has two major findings: We have found a significant discordance in risk assessment between prognostic tools (grade by local and central lab, Oncotype Dx, Ki-67). Patients treated by endocrine therapy alone based on very low Recurrence Score had an excellent disease free survival of 97% after 3 years of follow up. (more…)
