The patient's perspective

Abstract:In recent years there has been an increased focus on cancer patients information needs. The majority of the studies have led to the conclusion that most patients want as much information as possible about their disease and treatment. These studies have been large survey studies, and most of the patients enrolled in them have been out-patients. Very little is known about the information needs of severely ill cancer patients being treated as in-patients—such as those with acute myeloid leukaemia (AML). As part of a larger study dealing with AML patients illness narratives, this work describes the information needs from the patients perspective and their information-seeking behaviour. In-depth ethnographic interviews were conducted with each of 21 patients on two occasions: at the time of diagnosis and again 2–5xa0months later. Most patients did not recall much information from the time of diagnosis, except the diagnosis itself and the feelings it had aroused in them. All patients had basic medical knowledge about their disease. However, many patients—especially the elderly—expressed no need to receive further medical details about their disease. Avoiding information, in particular about the prognosis, was explained as a strategy to maintain hope. Most patients attached more importance to information about problems affecting their everyday life and how other persons had coped with their illness. They did not seek medical information on their own, although especially younger patients expressed the feeling that they ought to do this. There was a discrepancy between their expressed attitudes regarding the need for medical information in general and their actual information-seeking behaviour. Being informed and seeking information are discussed as societys expectations of todays cancer patient.

Arsenic trioxide and all-trans retinoic acid treatment for acute promyelocytic leukaemia in all risk groups (AML17): results of a randomised, controlled, phase 3 trial

BACKGROUNDnAcute promyelocytic leukaemia is a chemotherapy-sensitive subgroup of acute myeloid leukaemia characterised by the presence of the PML-RARA fusion transcript. The present standard of care, chemotherapy and all-trans retinoic acid (ATRA), results in a high proportion of patients being cured. In this study, we compare a chemotherapy-free ATRA and arsenic trioxide treatment regimen with the standard chemotherapy-based regimen (ATRA and idarubicin) in both high-risk and low-risk patients with acute promyelocytic leukaemia.nnnMETHODSnIn the randomised, controlled, multicentre, AML17 trial, eligible patients (aged ≥16 years) with acute promyelocytic leukaemia, confirmed by the presence of the PML-RARA transcript and without significant cardiac or pulmonary comorbidities or active malignancy, and who were not pregnant or breastfeeding, were enrolled from 81 UK hospitals and randomised 1:1 to receive treatment with ATRA and arsenic trioxide or ATRA and idarubicin. ATRA was given to participants in both groups in a daily divided oral dose of 45 mg/m(2) until remission, or until day 60, and then in a 2 weeks on-2 weeks off schedule. In the ATRA and idarubicin group, idarubicin was given intravenously at 12 mg/m(2) on days 2, 4, 6, and 8 of course 1, and then at 5 mg/m(2) on days 1-4 of course 2; mitoxantrone at 10 mg/m(2) on days 1-4 of course 3, and idarubicin at 12 mg/m(2) on day 1 of the final (fourth) course. In the ATRA and arsenic trioxide group, arsenic trioxide was given intravenously at 0·3 mg/kg on days 1-5 of each course, and at 0·25 mg/kg twice weekly in weeks 2-8 of course 1 and weeks 2-4 of courses 2-5. High-risk patients (those presenting with a white blood cell count >10u2008×u200810(9) cells per L) could receive an initial dose of the immunoconjugate gemtuzumab ozogamicin (6 mg/m(2) intravenously). Neither maintenance treatment nor CNS prophylaxis was given to patients in either group. All patients were monitored by real-time quantitative PCR. Allocation was by central computer minimisation, stratified by age, performance status, and de-novo versus secondary disease. The primary endpoint was quality of life on the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 global health status. All analyses are by intention to treat. This trial is registered with the ISRCTN registry, number ISRCTN55675535.nnnFINDINGSnBetween May 8, 2009, and Oct 3, 2013, 235 patients were enrolled and randomly assigned to ATRA and idarubicin (n=119) or ATRA and arsenic trioxide (n=116). Participants had a median age of 47 years (range 16-77; IQR 33-58) and included 57 high-risk patients. Quality of life did not differ significantly between the treatment groups (EORTC QLQ-C30 global functioning effect size 2·17 [95% CI -2·79 to 7·12; p=0·39]). Overall, 57 patients in the ATRA and idarubicin group and 40 patients in the ATRA and arsenic trioxide group reported grade 3-4 toxicities. After course 1 of treatment, grade 3-4 alopecia was reported in 23 (23%) of 98 patients in the ATRA and idarubicin group versus 5 (5%) of 95 in the ATRA and arsenic trioxide group, raised liver alanine transaminase in 11 (10%) of 108 versus 27 (25%) of 109, oral toxicity in 22 (19%) of 115 versus one (1%) of 109. After course 2 of treatment, grade 3-4 alopecia was reported in 25 (28%) of 89 patients in the ATRA and idarubicin group versus 2 (3%) of 77 in the ATRA and arsenic trioxide group; no other toxicities reached the 10% level. Patients in the ATRA and arsenic trioxide group had significantly less requirement for most aspects of supportive care than did those in the ATRA and idarubicin group.nnnINTERPRETATIONnATRA and arsenic trioxide is a feasible treatment in low-risk and high-risk patients with acute promyelocytic leukaemia, with a high cure rate and less relapse than, and survival not different to, ATRA and idarubicin, with a low incidence of liver toxicity. However, no improvement in quality of life was seen.

A randomized comparison of daunorubicin 90 mg/m2 vs 60 mg/m2 in AML induction: results from the UK NCRI AML17 trial in 1206 patients

Modifying induction therapy in acute myeloid leukemia (AML) may improve the remission rate and reduce the risk of relapse, thereby improving survival. Escalation of the daunorubicin dose to 90 mg/m(2) has shown benefit for some patient subgroups when compared with a dose of 45 mg/m(2), and has been recommended as a standard of care. However, 60 mg/m(2) is widely used and has never been directly compared with 90 mg/m(2). As part of the UK National Cancer Research Institute (NCRI) AML17 trial, 1206 adults with untreated AML or high-risk myelodysplastic syndrome, mostly younger than 60 years of age, were randomized to a first-induction course of chemotherapy, which delivered either 90 mg/m(2) or 60 mg/m(2) on days 1, 3, and 5 combined with cytosine arabinoside. All patients then received a second course that included daunorubicin 50 mg/m(2) on days 1, 3, and 5. There was no overall difference in complete remission rate (73% vs 75%; odds ratio, 1.07 [0.83-1.39]; P = .6) or in any recognized subgroup. The 60-day mortality was increased in the 90 mg/m(2) arm (10% vs 5% (hazard ratio [HR] 1.98 [1.30-3.02]; P = .001), which resulted in no difference in overall 2-year survival (59% vs 60%; HR, 1.16 [0.95-1.43]; P = .15). In an exploratory subgroup analysis, there was no subgroup that showed significant benefit, although there was a significant interaction by FLT3 ITD mutation. This trial is registered at http://www.isrctn.com as #ISRCTN55675535.

Epidemiology and Clinical Significance of Secondary and Therapy-Related Acute Myeloid Leukemia: A National Population-Based Cohort Study

PURPOSEnSecondary and therapy-related acute myeloid leukemia (sAML and tAML, respectively) remain therapeutic challenges. Still, it is unclear whether their inferior outcome compared with de novo acute myeloid leukemia (AML) varies as a result of previous hematologic disease or can be explained by differences in karyotype and/or age.nnnPATIENTS AND METHODSnIn a Danish national population-based study of 3,055 unselected patients with AML diagnosed from 2000 to 2013, we compared the frequencies and characteristics of tAML, myelodysplastic syndrome (MDS) -sAML, and non-MDS-sAML (chronic myelomonocytic leukemia and myeloproliferative neoplasia) versus de novo AML. Limited to intensive therapy patients, we compared chance of complete remission by logistic regression analysis and used a pseudo-value approach to compare relative risk (RR) of death at 90 days, 1 year, and 3 years, overall and stratified by age and karyotype. Results were given crude and adjusted with 95% CIs.nnnRESULTSnOverall, frequencies of sAML and tAML were 19.8% and 6.6%, respectively. sAML, but not tAML, was associated with low likelihood of receiving intensive treatment. Among intensive therapy patients (n = 1,567), antecedent myeloid disorder or prior cytotoxic exposure was associated with decreased complete remission rates and inferior survival (3-year adjusted RR for MDS-sAML, non-MDS-sAML, and tAML: RR, 1.14; 95% CI, 1.02 to 1.32; RR, 1.27; 95% CI, 1.16 to 1.34; and RR, 1.16; 95% CI, 1.03 to 1.32, respectively) compared with de novo AML. Among patients ≥ 60 years old and patients with adverse karyotype, previous MDS or tAML did not impact overall outcomes, whereas non-MDS-sAML was associated with inferior survival across age and cytogenetic risk groups (adverse risk cytogenetics: 1-year adjusted RR, 1.47; 95% CI, 1.23 to 1.76; patients ≥ 60 years old: 1-year adjusted RR, 1.31; 95% CI, 1.06 to 1.61).nnnCONCLUSIONnOur results support that de novo AML, sAML, and tAML are biologically and prognostically distinct subtypes of AML. Patients with non-MDS-sAML have dismal outcomes, independent of age and cytogenetics. Previous myeloid disorder, age, and cytogenetics are crucial determinants of outcomes and should be integrated in treatment recommendations for these patients.

Comorbidity and performance status in acute myeloid leukemia patients: a nation-wide population-based cohort study

As the world population ages, the comorbidity burden in acute myeloid leukemia (AML) patients increases. Evidence on how to integrate comorbidity measures into clinical decision-making is sparse. We determined the prognostic impact of comorbidity and World Health Organization Performance Status (PS) on achievement of complete remission and mortality in all Danish AML patients treated between 2000 and 2012 overall and stratified by age. Comorbidity was measured using a modified version of the Charlson Comorbidity Index, with separate adjustment for pre-leukemic conditions. Of 2792 patients, 1467 (52.5%) were allocated to intensive therapy. Of these patients, 76% did not have any comorbidities, 19% had one comorbid disease and 6% had two or more comorbidities. Low complete remission rates were associated with poor PS but not with comorbidity. Surprisingly, among all intensive therapy patients, presence of comorbidity was not associated with an increased short-term mortality (adjusted 90 day mortality rate (MR)=1.06 (95% confidence interval (CI)=0.76–1.48)) and, if any, only a slight increase in long-term mortality (91 day–3 year adjusted MR=1.18 (95%CI=0.97–1.44). Poor PS was strongly associated with an increased short- and long-term mortality (adjusted 90 day MR, PS⩾2=3.43 (95%CI=2.30–5.13); adjusted 91 day–3 year MR=1.35 (95%CI=1.06–1.74)). We propose that more patients with comorbidity may benefit from intensive chemotherapy.

Trends in hematological cancer in the elderly in Denmark, 1980–2012

Abstract Background The number of hematological malignancies is expected to increase as the Danish population ages within the next few decades. Despite this, data on the course of hematological cancers among the oldest patients are sparse with many intervention studies focusing on younger age groups. The aim of this study is to present Danish incidence and mortality rates among older patients with non-Hodgkin lymphomas (NHL), multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and acute myeloid leukemia (AML). Material and methods Nationwide population-based study presenting the incidence, prevalence and mortality rates of NHL, MM, and AML with a focus on the elderly population in Denmark during the last few decades. Data were drawn from the NORDCAN database. Results Incidence rates of NHL, MM, CLL and AML were 10–50 times higher among the population aged 70 years or more than among the younger population. An increasing incidence with stable or decreased mortality rates was seen mainly among elderly patients with NHL during the last few decades, leading to increased survival and a greater prevalence of patients with NHL. Increased relative survival and prevalence could also be seen among elderly patients with MM and CLL, while the trends of the incidence rates were inconclusive for these diseases. Survival among patients with AML improved most notably in those aged below 70 years leading to an increased prevalence of AML patients predominantly in this age group. Conclusion Improvements in diagnostics and treatment have led to increased survival and therefore prevalence of elderly patients with NHL, MM, CLL and AML during the past decades.

The Danish National Acute Leukemia Registry

Aim of database The main aim of the Danish National Acute Leukemia Registry (DNLR) was to obtain information about the epidemiology of the hematologic cancers acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and myelodysplastic syndrome (MDS). Study population The registry was established in January 2000 by the Danish Acute Leukemia Group and has been expanded over the years. It includes adult AML patients diagnosed in Denmark since 2000, ALL patients diagnosed since 2005, and MDS patients diagnosed since 2010. The coverage of leukemia patients exceeds 99%, and the coverage of MDS patients is currently 90%. Main variables and descriptive data Approximately, 250 AML patients, 25 ALL patients, and 230 MDS patients are registered in the DNLR every year. In January 2015, the registry included detailed patient characteristics, disease characteristics, treatment characteristics, and outcome data on more than 3,500 AML, 300 ALL, and 1,100 MDS patients. Many of the included prognostic variables have been found to be of high quality including positive predictive values and completeness exceeding 90%. These variables have been used in prognostic observational studies in the last few years. To ensure this high coverage, completeness, and quality of data, linkage to the Danish Civil Registration System and the Danish National Registry of Patients, and several programmed data entry checks are used. Conclusion The completeness and positive predictive values of the leukemia data have been found to be high. In recent years, the DNLR has shown to be an important high-quality resource for clinical prognostic research.

Effects of Education and Income on Treatment and Outcome in Patients With Acute Myeloid Leukemia in a Tax-Supported Health Care System: A National Population-Based Cohort Study

Purpose Previous US studies have shown that socioeconomic status (SES) affects survival in acute myeloid leukemia (AML). However, no large study has investigated the association between education or income and clinical characteristics, treatment, and outcome in AML. Methods To investigate the effects of education and income in a tax-supported health care system, we conducted a population-based study using individual-level SES and clinical data on all Danish patients with AML (2000 to 2014). We compared treatment intensity, allogeneic transplantation, and response rates by education and income level using logistic regression (odds ratios). We used Cox regression (hazard ratios [HRs]) to compare survival, adjusting for age, sex, SES, and clinical prognostic markers. Results Of 2,992 patients, 1,588 (53.1%) received intensive chemotherapy. Compared with low-education patients, highly educated patients more often received allogeneic transplantation (16.3% v 8.7%). In intensively treated patients younger than 60 years of age, increased mortality was observed in those with lower and medium education (1-year survival, 66.7%; adjusted HR, 1.47; 95% CI, 1.11 to 1.93; and 1-year survival, 67.6%; adjusted HR, 1.55; CI, 1.21 to 1.98, respectively) compared with higher education (1-year survival, 76.9%). Over the study period, 5-year survival improvements were limited to high-education patients (from 39% to 58%), increasing the survival gap between groups. In older patients, low-education patients received less intensive therapy (30% v 48%; adjusted odds ratio, 0.65; CI, 0.44 to 0.98) compared with high-education patients; however, remission rates and survival were not affected in those intensively treated. Income was not associated with therapy intensity, likelihood of complete remission, or survival (high income: adjusted HR, 1.0; medium income: adjusted HR, 0.96; 95% CI, 0.82 to 1.12; low income: adjusted HR, 1.06; CI, .88 to 1.27). Conclusion In a universal health care system, education level, but not income, affects transplantation rates and survival in younger patients with AML. Importantly, recent survival improvement has exclusively benefitted highly educated patients.

Outpatient management of intensively treated acute leukemia patients—the patients’ perspective

PurposeIn recent years, patients with acute leukemia (AL) have, to a greater extent, been managed in an outpatient setting where they live at home but appear every other day for follow-up visits at hospital. This qualitative article elucidates how patients with AL experience the different conditions of the inpatient and outpatient settings and how they reflect on these transitions in order to create meaning in and keep up everyday life.MethodsQualitative semi-structured individual interviews twice with each AL patient focusing on the outpatient setting, impact on everyday life, responsibility and the home were performed. Twenty-two patients were interviewed the first time, and 15 of these were interviewed the second time. The data were analyzed in an everyday life relational perspective.ResultsOutpatient management facilitates time to be administrated by the patients and thereby the possibility of maintaining everyday life, which was essential to the patients. The privacy ensured by the home was important to patients, and they accepted the necessary responsibility that came with it. However, time spent together with fellow patients and their relatives was an important and highly valued part of their social life.ConclusionsApproached from the patient perspective, outpatient management provided a motivation for patients as it ensured their presence at home and provided the possibility of taking part in everyday life of the family, despite severe illness and intensive treatment. This may suggest a potential for extending the outpatient management further and also for patient involvement in own care.

Systematic patient involvement for homebased outpatient administration of complex chemotherapy in acute leukemia and lymphoma

Based on experience with comprehensive patient involvement, we present data from implementation of portable, programmable infusion pumps (PPP) for home‐based chemotherapy administration in patients with acute leukaemia and in lymphoma patients receiving (carmustine, etoposide, cytarabine, melphalan) BEAM regimen. Data from 84 patients, receiving 177 cycles of PPP administered chemotherapy, showed convincing safety with minor equipment errors encountered and with high patient satisfaction. In‐hospital days could be reduced with 52% out of a total of 1197 treatment days. Homebased PPP has several advantages from a patient perspective and furthermore frees up in‐hospital beds for patients in need of them.
