MedicalResearch: What is the background for this study? What are the main findings?
Dr. Veenstra: Patients with cancer face many costs and incur financial burden as they go through diagnosis and treatment. For working patients, cancer diagnosis and treatment may come with the additional burden of time away from work, lost income, and even long-term job loss. Although 40% of US workers do not have access to paid sick leave, we hypothesized that availability of paid sick leave could reduce the need to take unpaid time away from work during cancer treatment and might therefore be associated with job retention and reduced personal financial burden.
In a survey of over 1300 patients with Stage III colorectal cancer, we found that only 55% of those who were employed at the time of their cancer diagnosis retained their jobs. Working patients with paid sick leave were nearly twice as likely to retain their jobs compared with working patients who did not have paid sick leave. This held true even when controlling for income, education and health insurance. Furthermore, working patients without paid sick reported significantly higher personal financial burden than those who had paid sick leave available.

Medical Research: What is the background for this study?
Dr. Rahman : Up to TIME1, the evidence base behind optimal pleurodesis for malignant pleural effusion in terms of tube size and analgesia was poor. Optimal pleurodesis in this context is one which is successful (i.e. the patient needs no further pleural interventions for that malignant effusion), but occurs with the minimum discomfort. This is particularly important as the treatment intent in malignant effusion pleurodesis is palliative.
This is the first adequately powered randomized trial to address two important issues in pleurodesis for malignant pleural effusion - that of whether NSAIDs reduce pleurodesis efficacy, and if smaller chest tubes (12F) are "as good as" larger chest tubes (24F) for pleurodesis success and in terms of pain.
Medical Research: What are the main findings?
Dr. Rahman : The main and somewhat surprising findings are that:

Medical Research: What is the background for this study? What are the main findings?
Dr. Freudenheim: There have been a number of studies that have shown an association between periodontal disease and chronic diseases, particularly stroke and heart attacks. There is also some newer evidence that periodontal disease is associated with cancer, particularly cancers of the gastrointestinal tract. Ours is the first large prospective study of periodontal disease and breast cancer.
This was part of a study of more than 70,000 postmenopausal women from throughout the United States, the Women’s Health Initiative. Women provided information about their health and other related factors and then those women were followed to see who developed certain diseases.
We found that women who had been told that they had periodontal disease were more likely to develop breast cancer. In particular, women who were former smokers (quit within the last 20 years) and who had periodontal disease were at increased breast cancer risk. There was a similar increase in risk for current smokers with periodontal disease but it was not statistically significant. (There was a relatively small number of current smokers in the WHI study.)

Medical Research: What is the background for this study? What are the main findings?
Dr. Tevaarwerk: These patients were enrolled on a larger clinical trial known as the Symptom Outcomes and Practice Patterns study (SOAPP). SOAPP recruited breast, prostate, colon and lung cancer patients directly during outpatient oncology follow-up visits. All of the patients were recruited between May 2006 and May 2008.
The parent study recruited 3123 patients, of these 680 patients had metastatic disease and 668 had employment data.
Patients were asked if they were working and if there had been a change due to illness. We were able to compare those stably working with those who had changed to "no longer working" and look at factors that associated with this change (age, gender, cancer type, race/ethnicity, time since diagnosis, location of metastatic disease, type of treatment, performance status, number of metastases, symptom burden.)

Associate Professor

Medical Research: What is the background for this FDA decision? What is the issue surrounding tanning beds?
Dr. Stein: This is an important proposal from the FDA because it restricts minors from tanning and requires adults to sign an acknowledgement stating they have been informed about the risks of tanning.
There is clear evidence that indoor tanning significantly increases a person’s risk for skin cancer, including melanoma, a potentially deadly form of skin cancer.
It is important to protect young people from the dangers of tanning beds, especially because many patients report that they started indoor tanning as teens. There are 1.6 million minors using tanning beds every year.
MedicalResearch: What is the problem with tanning? Isn't a tan better than a sunburn?
Dr. Stein: Tanning beds deliver intense amounts of UVA. We know that UVA penetrates deep into the skin and causes mutations that lead to skin cancers, including melanoma. Tanning is a sign that skin cells have been damaged by UV light.

Medical Research: What is the background for this study? What are the main findings?
Dr. Li Ding: Next-generation sequencing technologies have provided unprecedented opportunities for building a comprehensive catalog of point mutations, simple insertion and deletion mutations (indels) and structural variants in human cancers. Although significant progress has been made for documenting these common events through studies from individual research labs and large consortiums, there has been little progress in the discovery of complex indels after the transition from Sanger sequencing to NGS technologies. It is well known in the scientific community that indel detection using short next generation sequencing reads is a challenging problem. Our study, for the first time, directly addresses complex indel detection that has been barely touched in the cancer field. More importantly, our analysis discovered 285 complex indels in cancer genes such as PIK3R1, GATA3, and TP53, revealing an unexpected high prevalence of these events in human cancers.

MedicalResearch.com Interview with:
Roger Stupp, MD
Professor & Chairman
Department of Oncology & Cancer Center
University of Zurich & University Hospital Zurich (USZ)
Zürich / Switzerland
Medical Research: What is the background for this study?
Dr. Stupp: Tumor Treating Fields are an entirely novel modality in cancer treatment. Over 10 years ago researchers demonstrated that alternating electrical fields will block cell growth, interfere with organelle assembly, in particular perturb the spindle apparatus and cell division, all leading to mitotic arrest and ultimately apoptosis. This was shown in vitro, but importantly also in vivo animal models including not only mice and rats, but also hamsters and rabbits with deep seated solid tumours. So the question was whether we can demonstrate such an effect also in the clinic.
Glioblastoma are locally invasive and aggressive tumours in the brain. They usually do not metastasise however they grow diffusely within the CNS and despite the best possible surgery, radiation and chemotherapy virtually always recur. We thus applied alternating electrical fields therapy, so called Tumor Treating Fields to the scalp of patients with newly diagnosed glioblastoma. After the end of standard chemoradiotherapy (TMZ/RT), patients were randomized to receive either standard maintenance TMZ-chemotherapy alone or in combination with TTFields. Almost 700 patients were randomized, here we report on a preplanned interim analysis looking at the first 315 patients included once they were followed for at least 18 months. The data on the first 315 patients are mature and allowed the IDMC to conclude that the trial should be stopped and the results made available.
Medical Research: What are the main findings?
Dr. Stupp: The study demonstrated a consistent prolongation of both progression-free and also of overall survival for patients who have been treated with TTFields in addition to standard therapy. The median progression-free survival and overall survival were prolonged by 3 months, translating to an absolute increase in overall survival at 2 years of 14%, from 29% to 43%. Or a hazard ratio of 0.74 for overall survival and of 0.62 for progression-free survival.

Medical Research: What is the background for this study? What are the main findings?
Dr.Boolbol: The background for this study is predicated on the USPSTF's recommendations that there is insufficient evidence to continue the use of screening mammography in women over the age of 75. According to the American College of Radiology, cancer detection rates via screening mammography should be at least 2.5 per 1000 mammograms at an institution, with reported rates as high as 4.7 cases per 1000. We reviewed 2057 screening mammograms in women aged 75 and older. We found 10 cases of breast cancer in this group. Of these cancers, 60% were

Dr. Alexander: Thyroid nodular disease has become an increasingly common medical illness, with prevalence reported to range between 26-67% in the adult. Though advancing age is known to influence the formation of thyroid nodules, their precise relationship remains unclear. Furthermore, it is uncertain whether age influences the risk that any thyroid nodule may prove cancerous. Thus we conducted a study to determine the impact of patient age on nodule formation, the number of

Medical Research: What is the background for this study? What are the main findings?
Response: This study updates a previous study published in 2010 using the latest available data on cancer incidence and mortality from cancer and vital registration around the world. We found that while high-income countries still have the highest cancer rates in the world, some low- and middle-income countries now also have elevated cancer rates. Also, mortality rates for common cancers such as lung, breast, and colorectum are declining in high-income countries, while they are increasing in low-income countries. At the same time, low-income countries still have a disproportionate burden of infection-related cancers, such as stomach, liver, and cervix.

Staff oncologist at the Veterans Administration and a researcher in the Palo Alto Veterans Administration Health Services & Research Development group.
Medical Research: What is the background for this study?
Dr. Patel: Racial and ethnic disparities in Acute Leukemia are well documented in the literature but the reasons underlying the disparities remain largely unknown. In our previous work, we demonstrated mortality disparities for minorities with Acute Myeloid Leukemia despite favorable prognostic demographic and molecular factors. We have also shown that differences in receipt of treatment may partially explain a large component of these disparities. The purpose of this study is to determine how socioeconomic status factors influence mortality from Acute Leukemia using a population-based novel linked dataset of the Surveillance Epidemiology and End Results Database and the National Longitudinal Mortality Study.
Medical Research: What are the main findings?
Dr. Patel: We found a total of 121 patients with Acute Lymphoid Leukemia and 438 patients with Acute Myeloid Leukemia in the linked dataset. After adjusting for socioeconomic status factors, there were increased risk of mortality among Hispanic and decreased risk of mortality among Asian Pacific Islander patients as compared with non-Hispanic white patients in Acute Lymphocytic Leukemia. Among patients with Acute Myeloid Leukemia, we found no associations of mortality by race/ethnicity and socioeconomic status.

Medical Research: What is the background for this study? What are the main findings?
Dr. Dusetzina: As part of the Affordable Care Act the Medicare Part D “doughnut hole” is closing – reducing Medicare beneficiaries out-of-pocket expenses during this phase of coverage from 100% of drug costs to 25% between 2010 and 2020. In this study we analyzed 3,344 Medicare formularies that spell out how insurers cover prescription drugs. We found that in 2010, a typical course of oral chemotherapy drugs costs patients on average up to $8,100 per year. When the doughnut hole closes in 2020, patients will still have to pay on average $5,600 out of pocket per year, more than what the average Medicare beneficiary’s household spends on food each year. Even after the doughnut hold is closed oral chemotherapy drugs will still be out of reach for millions of Americans.

Medical Research: What is the background for this study? What are the main findings?
Dr. Chavez Mac Gregor: Adjuvant chemotherapy has proven to significantly decrease the risk of recurrence among breast cancer patients, however the optimal time to start adjuvant chemotherpay remains unknown. There are biological resasons to believe that a delay in the initiation of systemic therapy can be associated with adverse outcomes. In this large study we evaluated the impact of a delay in the initiation of time to chemotherapy (TTC). We analyzed data from 24,843 patients with invasive breast cancer (stages I to III) from the California Cancer Registry and observed that compared with patients who received chemotherapy within 31 days of surgery, no adverse outcomes were associated with time to chemotherapy of 31 to 90 days of surgery. However, there was a 34 % increase in the risk of death and a 27% increase in the risk of

Medical Research: What is the background for this study?
Dr. Radaelli: Split regimens of bowel preparation are strongly recommended by European and American Guidelines as they have been associated with a higher level of colon cleansing. However, there is still uncertainty on whether the higher level of cleansing associated with a split regimen also results in a higher proportion of subjects with at least one adenoma (adenoma detection rate, ADR), that represents by far a more relevant quality indicator than the level of cleansing itself.
On this background, we designed a randomized investigator-blinded controlled trial to evaluate whether a “split regimen” of low-volume 2-L PEG-ascorbate solution was superior to the traditional “full dose, the day before regimen” in terms of ADR. Differently from other studies on bowel preparation, we considered adenoma detection rate instead of the level of colon cleansing, the primary study end-point, and we designed the sample size accordingly. A precise estimation of the sample size was facilitated by including an homogeneous population of asymptomatic subjects undergoing first colonoscopy after positive-FIT within CRC organized screening program. Besides, ADR represents a very solid end-point due to the very low inter-pathology variability in the differential diagnosis between neoplastic and non-neoplastic lesions, while the assessment of the level of cleansing is hampered by unavoidable degree of subjectivity and higher degree of inter-operator variability.

MedicalResearch.com: What is the background for this report? What are the main findings?
Dr. Bhatnagar: I recently presented updated data regarding my research at the American Society for Radiation Oncology (ASTRO) annual meeting in a poster titled “Electronic brachytherapy for the treatment of Non-Melanoma Skin Cancer: Results up to 5 years.”
For this clinical study, I have been using the Xoft® Axxent® Electronic Brachytherapy (eBx®) System® which is FDA cleared, CE marked and licensed in Canada for the treatment of cancer anywhere in the body, including early-stage breast cancer, gynecological cancers, and nonmelanoma skin cancer (NMSC) including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
For the treatment of nonmelanoma skin cancer, the Xoft System uses a proprietary, miniaturized x-ray source to deliver a precise dose of targeted radiation directly to the surface lesion. This treatment uses electronic brachytherapy (eBx) to target cancerous cells while sparing healthy tissue. It is painless, non-invasive and offers a number of patient benefits, including fewer treatments than traditional radiation therapy.
According to my findings, the Xoft System is safe and effective for the treatment of nonmelanoma skin cancer, with low rates of recurrence and excellent clinical outcomes.

Dresden, Germany
Medical Research: What is the background for this study? What are the main findings?
Dr. Röllig: When this trial began in 2009, standard treatment for Acute Myelogenous Leukemia (AML) consisted of a combination of cytarabine plus anthracyclin/anthracendion and the need for improvement was obvious in the light of only around 50% long-term survivors even amongst younger patients. Although a promising approach, the use of kinase inhibitors in AML had not been shown to be beneficial and was not widely used. Sorafenib had been shown to be tolerable as single agent and in combination with commonly used chemotherapeutic agents. The results of the trial show that the addition of sorafenib to standard chemotherapy for newly diagnosed AML patients up to the age of 60 years is associated with significant prolongation of event-free survival and relapse-free survival compared to placebo plus standard chemotherapy. That means that patient who took sorafenib had less AML relapses.
To our knowledge, this is the first randomized-controlled showing that integrating a kinase inhibitor into standard intensive chemotherapy of younger patients with AML is associated with significant improvement of relapse-free survival, with no increase in treatment-related mortality. After a decade of evaluating the potential of kinase inhibitors in

Dr. Diefenbach: The background of the study is that through an understanding of the unique immunobiology of Hodgkin lymphoma we can derive rational treatment strategies which may heighten the efficacy of existing therapies, and improve the outcomes for patients with relapsed disease. In E4412 which is a national study sponsored by the Eastern Cooperative Oncology Group (ECOG-ACRIN) we explore the safety and efficacy of combination of the antibody drug conjugate brentuximab vedotin which targets CD30 on the surface of the Hodgkin lymphoma tumor cells, and immune stimulation of the T cells in the tumor microenvironment using checkpoint inhibitors. We reported the data from the first arm of the study Brentuximab Vedotin and Ipilimumab. To date 23 patients with relapsed Hodgkin lymphoma have been treated; the combination of brentuximab and

Houston, TX
Medical Research: What is the background for this study? What are the main findings?
Dr. Shinn: Recent studies with leukemia, breast, lung, renal and liver cancer patients have shown that patients with depression have worsened survival. These effect sizes are small, but independent of any of the traditional factors that are known to impact survival, such as extent of cancer, types of treatment administered and baseline health and age of the patient. The current thinking is that cancer patients who are depressed have chronically heightened responses to stress; the constant release of stress hormones trigger changes in the tumor itself (such as noradrenergically-driven tumor angiogenesis) or may weakens the body’s immune function and ability to resist tumor growth.
When we measured depression in newly diagnosed patients with oropharyngeal cancer (cancer of the base of tongue and tonsil), we found that those patients who scored as depressed were 3.5 times more likely to have died within the five year period after their diagnosis, compared to nondepressed patients. We also found that patients who were depressed were also 3.8 times more likely to have their cancer recur within the first five years after diagnosis. We also found that patients who continued to smoke after diagnosis were more likely to recur within the first five years. These effect sizes were larger than those typically found in recent studies. We believe that the larger effect size may be due to the tight eligibility criteria ( e.g., we did not include patients who already had recurrent disease, we only included patients with one specific type of head and neck cancer, oropharyngeal) and also due to controlling other known factors (all patients completed individualized treatment regimens of radiation/ chemoradiation at a comprehensive cancer center and patients with more advanced disease stage were more likely to have received treatment intensification compared to patients with early stage disease). In all, we had 130 patients, one of the largest prospective studies with oropharyngeal cancer to examine the effect of depression on cancer outcome.

Chia-Yu Chu, MD, PhD

Medical Research: What is the background for this study? What are the main findings?
Dr. Chia-Yu Chu: It has been well known that EGFR TKIs could cause skin toxicities (acneiform eruptions, pruritus, xerosis and paronychia). However, incidences of these skin toxicities have varied according to the different clinical trials, some of which even simply use “skin rash” instead of specific cutaneous findings in the reports.
Afatinib, in contrast to first generation EGFR TKIs like gefitinib and erlotinib, is a second generation EGFR TKI with irreversible inhibition to not only EGFR, but also HER2 and ErbB4. Whether afatinib cause more skin toxicities remained unknown.
Many of our patients received 2 or even 3 different EGFR TKIs with adequate drug exposure and washout period. Therefore, we had an opportunity to compare skin toxicities in “same patients” receiving different EGFR TKIs, and we found that around 30% of patients receiving afatinib developed paronychia whereas only 10% in gefetinib or erlotinib. This was the only significant difference between the 3 drugs. We also found afatinib treated patients needed significantly more dermatologic visits within 180 days of treatments and the reason was due to higher incidence of afatinib-related paronychia. Interestingly, regardless of causative agents, once skin toxicities developed they could be managed effectively in the same manners.

Medical Research: What is the background for this study? What are the main findings?
Dr. Smith: Several trials have demonstrated that agents (e.g. ) can be used to prevent breast cancer among women at increased risk. However, their effectiveness is dependent upon their appropriate use by this patient group. Several studies have suggested that uptake is low, and that women are not taking the medications for the full 5 year course. We attempted to synthesize the evidence investigating these topics, as well as identify the factors affecting these behaviours.
The main findings are that only 1 in 6 women (16.3%) were willing to start taking oral medications to prevent breast cancer.
Furthermore, uptake rates were lower in routine clinical practice (9%) compared with trial enrollment rates (25%), suggesting that there may be problems with implementing chemoprevention within routine clinical care. We noted that day to day adherence and persistence over a short period (e.g. 1 year) was adequate, but when looking at the longer term studies only 1 in 10 reported that >80% of women were still taking their medications at the 5 year end point. Women may not be experiencing the full preventive effect of these medications.

MedicalResearch: What is the background for this study? What are the main findings?
Dr. Nead: There are a growing number of studies suggesting that the use of Androgen Deprivation Therapy (ADT) may be associated with cognitive changes and some of these changes overlap with characteristic features of Alzheimer’s disease. In addition, low testosterone levels have been associated with Alzheimer’s disease risk and ADT lowers testosterone levels. Despite these findings, we could not identify any studies examining the association between ADT and Alzheimer’s disease risk. We therefore felt this study could make an important contribution in guiding future research to fully understand the relative risks and benefits of ADT.
We examined electronic medical record data from Stanford University and Mt. Sinai hospitals to identify a cohort of 16,888 patients with prostate cancer. We found that men with prostate cancer who received Androgen Deprivation Therapy were more likely to develop Alzheimer’s disease than men who did not receive

Dr. Puig: CDKN2A is the main high-penetrance melanoma susceptibility gene. A rare functional variant in MITF, p.E318K (rs149617956), has been identified as a moderate risk allele in melanoma susceptibility and also predisposes to renal cell carcinoma.
In this study MITF p.E318K was associated with an increased melanoma risk (OR=3.3, p<0.01), especially in patients with multiple primary melanoma (OR=4.5, p<0.01) and high nevi count (>200 nevi) (OR=8.4, p<0.01). Interestingly, two fast growing melanomas were detected among two MITF p.E318K carriers during dermatologic digital follow-up. Furthermore, we have detected a similar prevalence of MITF p.E318K in CDKN2A wild-type and mutated individuals.

Medical Research: What is the background for this study? What are the main findings?
Response: The background of this presentation is as follows: For many years, we have seen intriguing - but also sometimes conflicting - results of trials using adjuvant bone-targeted therapy.
ABCSG-18 is a placebo-controlled trial of adjuvant denosumab 60mg twice yearly, and I have been able to present to you at this year’s ASCO meeting the dramatic reduction in clinical fractures which was the primary end point of the trial. We have also showed that twice yearly denosumab can be administered without added toxicity in this double-blind placebo-controlled trial. These results were as well published in the Lancet earlier this year.
The obvious question remaining now is whether adjuvant treatment with the anti-RANK ligand antibody also improves outcomes in a way similar to what bisphosphonates do.
Main findings of ABCSG-18: disease-free survival results of the intention-to-treat analysis: In the placebo group, we observed 203 DFS events. In the denosumab group, there were 167 DFS events, resulting in a hazard ratio of 0.816, indicating an 18% relative DFS improvement by denosumab. In terms of absolute differences, the benefit was 1.2% at 3 years, 2.1% at 5 years, and 3.1% at 7 years.
