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

Response: Historically, the cost of healthcare can be a substantial burden for cancer survivors and their families in the US. Even with health insurance, a cancer diagnosis can impose significant out-of-pocket costs for medical care.  These are partially due to the rising costs of cancer treatments in recent years, moreover, the increasing levels of coinsurance, copayments, and deductibles also shift a significant portion of the burden to cancer patients.

We found that younger cancer survivors, those aged 18-49 years, bear a higher burden than their older counterparts. We also found that two-thirds of cancer survivors enrolled in high-deductible health plans did not have health savings accounts, and they are more vulnerable to financial hardship than those in high-deductible health plans with health savings accounts and those covered by low-deductible plans.

These findings are important to patients because although cancer patents have benefited from newer and more advanced treatments, financial hardship may lead to emotional distress, cause changes in health behaviors, and jeopardize treatment adherence and health outcomes.

Anders Rabbe
CEO of Isofol Medical

MedicalResearch.com: What is the background for this study? How common is colorectal cancer? 

Response: Colorectal cancer (CRC) is one of the most common forms of cancer with more than 1.8 million new cases identified globally every year. Due to a lack of new therapeutic options and a high mortality rate, colorectal cancer is a disease with a significant unmet need for effective new treatments.

Isofol is developing arfolitixorin (Modufolin®) to improve the efficacy of standard of care chemotherapy for advanced colorectal cancer. Arfolitixorin is the company’s proprietary drug candidate currently being studied in a global Phase 3 AGENT study (ISO-CC-007) as a first-line treatment for patients with metastatic colorectal cancer (mCRC), which just enrolled its first patient in December of 2018.

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

Response: Patients requiring surgery for esophageal cancer fare better after undergoing a hybrid minimally invasive esophagectomy (HMIE) with a combined laparoscopy+thoracotomy procedure compared to an open esophagectomy (OE), according to results of the MIRO trial published in the last issue of the New England Journal Of Medicine (link article).

This French prospective multi-center randomized controlled study was funded by the French National Cancer Institute (Grant n° 1907). The study was conducted by Pr Mariette who sadely passed away in 2017 and Pr Piessen (Department of Digestive and Oncological Surgery, CHU Lille), under the hauspice of FRENCH (Fédération de Recherche EN Chirurgie) and FREGAT (French Eso-Gastric Tumors) working group (https://www.fregat-database.org/fr/).

Postoperative morbidity, especially pulmonary complications, affects more than half of patients after open esophagectomy for esophageal cancer.

Hybrid minimally invasive esophagectomy (HMIE) combines a laparoscopic abdominal phase with an open thoracotomy, which may have specific advantages including lower rate of pulmonary complications, without laparoscopic tumor dissection limiting potential tumor spillage and easier reproducibility of the technique [12].

WHO: Profits Outweigh R&D Costs of New Cancer Drugs

MedicalResearch.com Interview with:

Kiu Tay-Teo, PhD World Health Organization Geneva, Switzerland

Dr. Kiu Tay-Teo

Kiu Tay-Teo, PhD

MedicalResearch.com: What are the main findings?

Response: High costs and high risks of R&D for drugs have been presented to justify high drug prices, especially for cancer drugs. However, it is unclear whether prices are in fact justifiable compared to the overall return on R&D investment.

In this paper, we systematically compared incomes from the sales of cancer drugs with the R&D costs. We quantified the incomes generated from the sales of 99 cancer drugs approved by FDA from 1989–2017. This was based on sales figures reported in the originator companies’ annual financial reports, and where necessary, estimates deduced from the reported figures. The sales incomes were net of rebates and discounts, but without accounting for expenses and taxes. For the R&D costs of bringing one new cancer drug to the market, the literature reported a typical costs of between $219 million and $2.9 billion, after accounting for the costs of failed products that were investigated but not marketed and the opportunity costs. For the main analysis, we used a median cost of $794 million, as reported in the literature. To be clear, this analysis did not estimate profit return because we do not have information about the costs and year-to-year variations in costs (i.e. expenses and taxes) specific to cancer drugs.

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

Response: Despite variations in excess body weight (EBW) prevalence among states in the United States, there was little information on the proportion of incident cancers attributable to EBW (or population attributable fraction, PAF) by state. This information would be useful to help states set priorities for cancer control initiatives.

In this paper, we estimated the PAF and number of incident cancer cases attributable to EBW by sex in all 50 states and the District of Columbia using representative exposure and cancer occurrence data. To provide more accurate estimates, we adjusted state-level data on body mass index (BMI) based on self-reported weight and height from the Behavioral Risk Factor Surveillance System by sex, age group, race/ethnicity, and education level (162 strata) using BMI values from the National Health and Nutrition Examination Survey, a nationally representative survey with objectively-measured height and weight.

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

Response: Herpes zoster is a neurocutaneous disease caused by the reactivation of latent varicella zoster virus and its risk is related to the cell-mediated immunity. Previous studies have reported a higher zoster risk among patients with haematological cancer and cancer patients receiving chemotherapy. However, the role of the cancer itself and the receipt of cancer treatment is not clearly separated, we therefore started this study and tried to separate the risk of zoster associated with the cancer itself from cancer treatment.  Continue reading

Some Anti-Tumor Drugs May Promote Delayed Aggressive Cancers

MedicalResearch.comInterview with:
Alexandra Avgustinova PhD
Postdoctoral fellow at the Institute for Research in Biomedicine (IRBBarcelona)

Dr. Avgustinova
Dr. Avgustinova

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

Response: The basis of this study was the strong association between closed chromatin and high mutation rate reported several years ago. We were surprised to see this observation being widely interpreted as a causal association, as it was largely based on correlative studies without experimental backing. Therefore we decided to experimentally test for the first time whether indeed altering chromatin opening would affect mutation rate or distribution within tumours.

MedicalResearch.com: What are the main findings?

Response: We found that, despite significantly increasing chromatin opening, loss of the histone methyltransferase G9a did not have any major influence on the mutation rate or distribution within cutaneous squamous cell carcinomas. These results demonstrate that chromatin opening does not play a major role in determining the mutation rate within tumours, and we speculate that other, confounded factors (e.g. replication timing or H3K36me3 levels) are likely causal for the observed association. This, however, remains to be proven experimentally.

Another major conclusion of our study was that although tumour initiation was delayed and tumour burden decreased in the absence of G9a, the tumours that did develop were highly aggressive due to selection for more aggressive tumour clones. This finding was contrary to many published reports suggesting G9a as a good candidate for clinical targeting, highlighting the need for long-term follow-up in pre-clinical studies.

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

Response: Polycystic ovary syndrome (PCOS) is the most common endocrine    disorder affecting 5-10% of women of reproductive age. Characterized by hyperandrogenism and metabolic abnormalities, PCOS is known to be related to various long-term health consequences, including diabetes, cardiovascular disease and endometrial cancer. Besides, inconsistent results have been reported for the associations between PCOS and the risk of ovarian and breast cancer. Studies addressing the risks of other cancers are scarce. Thus, we conducted a large, population-based cohort study with a long follow-up and rather sufficient confounding adjustment to explore the full picture of associations between PCOS and the risks of various cancer types.

We found that PCOS is a risk factor for certain types of cancer, including cancers of the endometrium, ovary, endocrine gland, pancreas, kidney and skeletal & hematopoietic system. Continue reading

Daily Drinking is Dangerous

Assistant Professor
Department of Psychiatry
Washington University School of Medicine in St. Louis

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

Response: This study is the first to show that daily drinking is dangerous. Specifically, drinking four or more times weekly, even if it’s only 1-2 drinks at a time, increases risk of mortality. This is in line with recent studies published in the Lancet, but we were able to break down their lowest drinking categories (up to 12.5 drinks weekly in one and up to 5.6 drinks weekly in the other) and found that the frequency is important, not just the average number of drinks per week. It looks like the increased mortality is predominantly due to cancer-related deaths.

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

Response: Among the environmental risk factors for cancer, there are concerns about exposure to different classes of pesticides, notably through occupational exposure. Organic foods are less likely to contain pesticide residues than conventional foods, and studies have showed that an organic diet reduces exposure to certain pesticides (Baudry et al 2018, Oates et al 2014, Curl et al 2015). In the general population, the primary route of exposure is diet, especially intake of conventionally grown fruits and vegetables. However, few studies have examined the association of organic food consumption with cancer risk.

In a population of 68 946 French adults from the NutriNet-Santé study, we found a reduction of 25% of cancer risk among consumers with a high frequency of organic foods compared to consumers with a low frequency, after accounting for many factors (such as lifestyle, diet and sociodemographic factors). Specifically a 34% and 76% decrease in risk was observed for post-menopausal breast cancer and all lymphomas, respectively, among frequent organic food consumers compared to consumers with a low organic food consumption frequency.

TumorScan May Become a Universal Screening Blood Test For Cancer

Professor Diana Anderson Established Chair in Biomedical Sciences The University of Bradford Richmond Road Bradford West Yorkshire

Prof Anderson

The University of Bradford Richmond Road Bradford West Yorkshire

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

Response: I have worked in this field for over 40 years both as a research scientist in industry and as a university-based researcher. It has always been my ambition to develop a relatively simple and affordable test to predict if a person is sensitive to cancer. In fact, in 1974, I was appointed as Head of Mutagenesis Studies at ICI’s Central Toxicology Laboratory in Manchester, UK, and I was looking at developing a short-term test to predict cancer even back then.

Our ‘universal’ cancer test is different from other ‘universal’ tests being developed, because ours is not looking for a specific biomarker or mutation. Ours is a generic test for cancer in an individual, regardless of any underlying mechanism that’s causing their cancer.

It is known that levels of damage to the DNA in the cellular genome can correlate with cancer and this is what we set out to investigate with the Comet assay.

Of the available tests to detect damage to the genome the Comet assay is very straightforward. This assay was primarily developed as a method to measure DNA damage. Briefly, cells are embedded in agarose on a microscope slide and lysed to remove membranes leaving supercoiled DNA loops, breaks in which after alkaline treatment and alkaline electrophoresis move towards a positive charge. The DNA is stained with a fluorescent dye and visualised by fluorescent microscopy. The image is like Haley‘s comet and the greater number of breaks the greater is the migration to the anode and the greater the damage.  Continue reading

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

Response: The choice of correct individualized therapy for breast cancer depends on correct diagnosis: receptors for estrogen, progesterone and HER2 are determined routinely. However 5-10% of these routine diagnostics are inaccurate and may entail suboptimal therapy.

We have paved the way for additional diagnostics from gene expression data so as to increase precision of diagnostics. Continue reading

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

Response: There is evidence from randomized controlled trials that exercise has beneficial effects on physical fitness, fatigue, quality of life and self-reported physical function during and following cancer treatment. The magnitude of the effects, however, often appear modest, possibly because interventions rarely target patients with worse symptoms and quality of life.

Based on individual patient data from 34 randomized controlled trials, we found that exercise interventions during cancer treatment are effective in maintaining muscle strength and quality of life, regardless of their baseline values.

Offering exercise interventions post cancer treatment to patients with a relatively high muscle strength and quality of life does not appear to further improve these outcomes. For aerobic fitness, exercise interventions during treatment had larger effects in patients with higher baseline aerobic fitness, whereas all patients were able to improve aerobic fitness post treatment. Greater effects on fatigue and self-reported physical function were found for patients with worse baseline fatigue and physical function, both during and post-treatment.

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

Response: Obesity, a major healthcare burden, is an established risk factor for many gastrointestinal cancers. With obesity being on the rise, we inspected whether obesity related gastrointestinal cancers are increasing in different age groups, and relation to obesity.

MedicalResearch.com: What are the main findings? 

Response: We identify an alarming increase in incidence of gastric and colorectal cancers in young adults (less than 50 years of age) between 2002-2013.

This was paralleled by an uptrend in obese patients undergoing surgeries for these cancers during the same period. 

MedicalResearch.com: What should readers take away from your report?

Response: Our results suggest, for the first time, a contributing role of obesity in the etiology as well as the increasing incidence of gastric and colorectal cancers in young adults. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: More studies are needed to investigate the interplay of epigenetics factors such as young-onset obesity and western diet in relation to risk of adults developing colorectal and gastric cancers at an earlier age. Also public policies are needed to counter obesity and the rising incidence of gastric and colorectal cancer in this young high risk group.

MedicalResearch.com: Is there anything else you would like to add?

Response: My main career focus is translational and clinical research at the interface of energy balance, the microbiome and gastrointestinal cancer.

We have no financial disclosers or conflict of interest.

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

Response: Our team at Memorial Sloan Kettering has been investigating the intestinal microbiota of patients receiving bone marrow transplantations for more than eight years now. We have found through several studies that these patients lose important healthy bacteria from their microbiota, and that these losses are mostly caused by the antibiotics given as prophylaxis or to treat infections.

We also found that the drastic changes in the microbiota composition, especially the intestinal dominations by bacteria such as Enterococcus, increase the risk of transplant-related complications and lowered patient survival.

We aimed to determine the feasibility of autologous microbiota transplant (auto-FMT) as a way to reconstitute lost bacteria. This randomized study found that indeed auto-FMT could reconstitute important microbial groups to patients.  Continue reading

High-Risk Gleason 5 Prostate Cancers Not Resistant to Androgen Deprivation Therapy

MedicalResearch.com Interview with:

Amar U. Kishan, MD Assistant Professor Department of Radiation Oncology University of California, Los Angeles

Dr. Kishan

Amar U. Kishan, MD
Assistant Professor
Department of Radiation Oncology
University of California, Los Angeles

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

Response: Three large randomized trials demonstrated an overall survival (OS) benefit when androgen deprivation therapy (ADT) is combined with radiotherapy (RT) for high-risk prostate cancer (PCa). The duration of ADT in these seminal studies ranged from six months to lifelong. Because ADT has multiple attendant adverse effects–including bone loss, altered metabolism, diminished muscle mass, gynecomastia, hot flashes, and possibly increased cardiovascular events–shortening the duration of ADT without compromising oncologic effectiveness has been an area of active study. Five trials have compared various durations of ADT, reaching conflicting conclusions with respect to overall survival outcomes, with some suggesting an improvement with longer durations of ADT and others failing to show a uniform survival benefit.

Most of these trials have amalgamated Gleason grade group 4 (Gleason score 8) PCa with Gleason grade group (GG) 5 (Gleason score 9-10) PCa. Emerging data indicate that GS 9-10 PCa constitutes a distinct subset of high-risk PCa with inferior outcomes and earlier progression than GS 8 disease. With the knowledge that GS 9-10 PCas constitute a distinct, more aggressive form of PCa, one might hypothesize that longer durations of ADT may be more advantageous in both augmenting local control and controlling potential micrometastatic disease. Alternatively, as GS 9-10 lesions by definition contain highly de-differentiated Gleason pattern 5 disease foci and may proceed to a castrate-resistant state more rapidly, one may also hypothesize that GS 9-10 lesions are less responsive to ADT, and longer durations may be counter-productive.

In order to identify differences in the impact of ADT duration on clinical outcomes of patients with GG 4 and GG 5 PCa, we performed an individual patient-level meta-analysis of six randomized trials. Our working hypothesis was that longer durations of ADT would offer significant survival benefits in both groups.

Factor in Quality of Life When Deciding Radiotherapy vs Surgery in Patients With Oropharyngeal Cancer

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

Response: The prevalence of oropharyngeal cancer is rising rapidly, and the two primary therapeutic approaches – upfront radiation therapy or surgery resection – have both been improving in terms of acute and late toxicity profiles. There is significant debate as to which therapy is better, and comparative data are necessary to help physicians and patients decide which paradigm is preferred for a given clinical scenario. Although there is a lot of anecdotal experience in comparing the two treatments, there really is a lack of published data on the question, and this is where our study fits in. 

MedicalResearch.com: What is the background for this study? Were there significant quality-of-life differences between the two treatment modalities?

Response: The main findings were comparable outcomes in long-term survival, toxicity and even cost between primary radiation therapy and primary surgery. This equivalence highlights the importance of patient-centered decision-making and engaging patient preferences in their optimal treatment approach. There was clearly an increase in stomach tube use in patients receiving primary chemoradiotherapy, which may be an important consideration in some patients, depending on the expected functional outcome of initial surgery. This difference became non-significant after a short period of time, but it was real and may influence decision-making.

MedicalResearch.com: What should readers take away from your report?

Response: Readers should take away that there are no particularly large differences between these treatments. Survival, toxicity and cost are all comparable in the long-run. It was quite clear, though, that primary surgery was associated with a lower risk of gastrostomy tube use. Although the difference in tube use was negligible within a few months, the use of any feeding tube may be a deciding factor for some patients. We showed here this difference was due to concurrent chemotherapy during radiotherapy. This result echoes our clinical experience, but we were able to show this finding quite clearly. On the other hand, we also found that the increased dependence with radiation therapy was clearly short-lived, so patients should absolutely not consider this difference as a long-term problem preferentially associated with radiotherapy.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: It is critical for future research to consider the functional and quality-of-life outcomes in future comparisons of these different treatment approaches. Claims-based analyses such as this can uniquely show the “big picture” with respect to complications that require a medical treatment. However, more granular and subtle patient-reported outcomes are not included in this study, and they will be essential to help patients and physicians in the decision-making process.   

The study was funded by the Radiation Oncology Institute.

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

Response: We wanted to better understand why certain patients infected with H. pylori developed stomach cancer and how we could better identify them. H. pylori is one of the strongest risk factors for stomach cancer, but how much it predisposes individuals to gastric cancer varies around the world.

Working closely with colleagues from Zhengzhou University, we ran tests on 49 samples from China and found that 91 percent of patients infected with the EPIYA D gene variant of H. pylori also had stomach cancer. Continue reading

Complex Racial and Ethnic Disparities in Childhood Cancer Survival

MedicalResearch.com Interview with:
Rebecca D. Kehm, PhD
Division of Epidemiology and Community Health
University of Minnesota School of Public Health
Minneapolis, MN  

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

Response: Racial and ethnic differences in childhood cancer survival have long been known, and there has been some research indicating that SES could explain disparities. However, our study is the first to use statistical methods that put numbers to the relative contribution of SES to survival disparities for different types of childhood cancer. We set out to investigate whether racial and ethnic disparities in childhood cancer survival are attributed to underlying differences in socioeconomic status, defined as one’s social and economic position in relation to others based on income, education, and occupation, which scientists abbreviate as SES. Our findings provide evidence that SES does in fact contribute to racial and ethnic disparities in survival for some types of childhood cancer. Specifically, we found that SES accounted for 28-73% of the racial and ethnic survival disparity for acute lymphoblastic leukemia, acute myeloid leukemia, neuroblastoma, and non-Hodgkin lymphoma. However, SES did not significantly contribute to racial and ethnic disparities in survival for other types of childhood cancer including central nervous system tumors, soft tissue sarcomas, Hodgkin lymphoma, Wilms tumor, and germ cell tumors. These tumor-specific results help inform where to place resources to best reduce racial and ethnic survival disparities for each of the major types of childhood cancer.

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

Response: Our colleagues in the U.S. have been working on KIM-1 for years, particularly in the context of chronic kidney disease. Recently they found that KIM-1 is also elevated at the time of diagnosis of kidney cancer.

We wanted to see if KIM-1 concentrations could predict the chances of a future diagnosis of kidney cancer. We found that KIM-1 was a strong predictor of being diagnosis with kidney cancer in the next 5 years. We also found that higher pre-diagnostic KIM-1 was associated with worse survival after diagnosis.  Continue reading

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

Response: The drug-induced long QT syndrome (diLQTS) is a problem for clinicians balancing risk and benefits across multiple therapeutic areas, and for pharmaceutical scientists and regulators evaluating new drug candidates. The prevalent view is that block of a specific ion current, the rapid component of the cardiac delayed rectifier (IKr), is the common mechanism predisposing to diLQTS across drug classes and that patients with mutations in ion channel genes are at especially increased risk. In the very extreme form of diLQTS, a specific form of ventricular arrhythmia potentially lethal, called Torsade de Pointes, can occur. All IKr blocking drugs do not confer the same Torsade de Pointes risk; the risk with antiarrhythmics such as sotalol or dofetilide can be 1-2%, while the risk with IKr-blocking antibiotics such as moxifloxacin is much lower, <1/20,000.

Women are at higher risk of diLQTS than men. Androgens are protective. Influence of hormonal contraception on diTdP and QT prolongation is controversial

MedicalResearch.com: Were you surprised by the study findings, why or why not? 

Response: We were not really surprised because the influence of testosterone (the main androgenic hormone) to shorten the duration of cardiac repolarization was already known. We wanted to see if this effect was also present with contraceptive pills with various androgenic-like activities.

MedicalResearch.com: Can you explain what exactly is “sotalol-induced QTc prolongation”? 

Response: After each heartbeat, the heart recovers to normal. This phenomenon is called ventricular repolarization and can be assessed on the electrocardiogram by measuring the duration of a parameter called QT interval. This QT interval is influenced by many factors one of them being heart rate. QT interval is therefore corrected for the heart rate observed at the time of its measurement (QTc). Sotalol is one of several drugs given to prolong ventricular repolarization, and hence QTc, as a mean to prevent the recurrence of some disturbances of heart beats. These disturbances are called arrhythmias. However, drugs which prolong QTc can also provoke a very rare arrhythmia which can cause cardiac arrest or the heart to stops. Only rare susceptible patients are at risk of having this drug-induced arrhythmia and most patients who receive sotalol and have prolonged QTc are doing well. 

MedicalResearch.com: What were the drug-induced alterations in “ventricular repolarization” seen among the women? 

Response: The alterations of ventricular repolarization were those expected with sotalol: prolongation of QTc interval and changes is the morphology of the T-wave which is part of the QT interval. What we found is that the extent of QTc prolongation and T-wave morphological changes caused by sotalol was greater in women who were receiving the anti-androgenic contraceptive pill drospirenone compared with levonorgestrel. This is in line with the known effect of androgens to shorten ventricular repolarization in men but it was not known to be influenced by the progestin androgenic activity of oral contraceptives in women. 

MedicalResearch.com: What new information does this study provide to the scientific literature on oral contraceptives? 

Response: We did not show that oral contraceptives influence ventricular repolarization. This was not the purpose of the study. Our study, with its limitations, suggests that the type of oral contraceptive can influence the effects of drugs such as sotalol which prolong QTc. Drospirenone, an oral contraceptive with antiandrogenic properties, was associated with greater drug-induced QTc prolongation than levonorgestrel, an oral contraceptive with androgenic activity. Whether this is associated with a greater risk of provoking arrhythmias with antiandrogenic pills is not proven although there are indirect indications from an analysis of the European pharmacovigilance database, that this might be the case. Additional studies need to be performed to better assess this risk.

MedicalResearch.com: What were some limitations of the study? 

Response: The type of oral contraceptive taken by women participating in the study was prescribed by their physician and women receiving different oral contraceptives may have differed in their response to sotalol for other reasons. In other words, oral contraceptives were not administered by chance to the women (the study was not randomized but observational) and this is not the most robust method to examine the influence drugs in general. Also, the level of the natural sex hormones in the blood of the study participants was not measured and it may have influenced QTc interval  

MedicalResearch.com: Why is this study important? 

Response: In spite of its limitations, our study prompts for a more thorough assessment of the influence of progestin androgenic activity of oral contraceptives on drug-induced QTc interval prolongation and the risk of associated arrhythmias. It also emphasizes the importance of androgens as a factor limiting the risk of QTc prolongation in patients receiving drugs which prolong ventricular repolarization.

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

Response: Allogeneic bone marrow transplantation BMT is used with a curative intent for life-threatening malignant and non-malignant diseases of childhood.

In this observational study, we describe the late mortality experienced by children undergoing BMT over the past 3 decades. Our cohort included 1388 BMT recipients who had undergone allogeneic BMT between 1974 and 2010 and survived 2 or more years.

We found that, conditional on surviving the first 2 years after bone marrow transplantation, the probability of surviving an additional 20 years approached 80%. Risk of dying from non-relapse-related causes exceeded the risk of dying from relapse-related causes.

The leading non-relapse-related causes of death were infection (with or without graft vs. host disease) and new cancers. Overall, the cohort was at a 14-fold greater risk of dying as compared with the general population (of similar age and sex). Further, this excess risk remained elevated even among those who had survived 25 years.

On a positive note, the risk of late mortality has continued to decline over the past 3 decades.

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

Response: In prior work, many patients with advanced stages of cancer report a lack of understanding of their prognosis and receipt of care that differs from their preferences.

These gaps in care delivery along with the unsustainable rise in healthcare spending at the end-of-life and professional healthcare provider shortages led our team to consider new ways to deliver cancer care for patients.  Based on input from focus groups with patients, caregivers, oncology care providers and healthcare payers, we designed a novel model of cancer care to address these gaps in care delivery.  The intervention consisted of a well-trained lay health worker to assist patients with understanding and communicating their goals of care with their oncology providers and caregivers.

We found that patients who received the six-month intervention reported greater satisfaction with the care they received and their decision-making, had higher rates of hospice use, lower acute care use, and 95% lower total healthcare expenditures in the last month of life.  The intervention resulted in nearly $3 million dollars in healthcare savings.
