Living with and beyond cancer: patients experience persisting consequences of their cancer and its treatment

In Nederland leven momenteel meer dan 800.000 mensen met of na kanker en dit aantal neemt toe. Zij kunnen te maken krijgen met uiteenlopende gevolgen van kanker en de behandeling, zowel op lichamelijk, emotioneel, psychosociaal als maatschappelijk vlak. Deze gevolgen zijn ingrijpend en vaak blijvend van aard. Ten minste een kwart van de mensen die leeft met of na kanker ervaart - ook langere tijd na behandeling - angst, vermoeidheid en problemen met seksualiteit. In vergelijking met een normpopulatie van dezelfde leeftijd en geslacht zijn meer dan twee keer zo vaak neuropathie (14% versus 4%), sociale belemmeringen (13% versus 5%) en angstklachten (30% versus 12%) gerapporteerd. Door binnen de gezondheidszorg consequent aandacht te hebben voor deze gevolgen, zowel tijdens als na het behandeltraject, kunnen we mensen die leven met en na kanker zo goed mogelijke ondersteuning bieden. Aandacht voor gevolgen omvat daarbij zowel het geven van voldoende informatie, het tijdig signaleren, het ondersteunen als ook het behandelen van gevolgen

Distress and quality of life after autologous stem cell transplantation: a randomized clinical trial to evaluate the outcome of a web-based stepped care intervention

Background Psychological distress (i.e. depression and anxiety) is a strong predictor of functional status and other aspects of quality of life in autologous stem cell transplantation following high-dose chemotherapy. Treatment of psychological distress is hypothesized to result in improvement of functional status and other aspects of quality of life. The aim is to evaluate the outcome of stepped care for psychological distress on functional status and other aspects of quality of life in patients with hematological malignancy treated with autologous stem cell transplantation. Methods/Design The study is designed as a randomized clinical trial with 2 treatment arms: a stepped care intervention program versus care as usual. Patients are randomized immediately pre transplant. Stepped care and care as usual are initiated after a 6 weeks buffer period. Outcome is evaluated at 13, 30, and 42 weeks post transplant. In the experimental group, the first step includes an Internet-based self-help program. If psychological distress persists after the self-help intervention, the second step of the program is executed, i.e. a diagnostic evaluation and a standardized interview, yielding a problem analysis. Based on this information, a contract is made with the patient and treatment is provided consisting of individual face-to-face counseling, medication, or referral to other services. Care as usual comprises an interview with the patient, on ad hoc basis; emotional support and advice, on ad hoc basis; if urgent problems emerge, the patient is referred to other services. Primary outcome variables are psychological distress and functional status. Data are analyzed according to the intention to treat-principle. Discussion This study has several innovative characteristics. First, the outcome of the intervention for psychological distress in patients with hematological malignancy treated with autologous stem cell transplantation is evaluated in a randomized controlled study. Second, the impact of the intervention on functional status is evaluated: it is hypothesized that reduction of psychological distress results in improved functional status. Furthermore, the intervention concerns an Internet-based treatment in the first step. Finally, the intervention is characterized by an emphasis on self-management, efficiency, and a multi-disciplinary approach with nurses taking up a central role

Regulation of megakaryocytopoiesis in an in vitro stroma model: Preferential adhesion of megakaryocytic progenitors and subsequent inhibition of maturation

Objective. Studies of megakaryocytic progenitor cell interactions have focused on single receptor-ligand interactions using isolated components of the extracellular matrix. To approach a physiologic condition, we studied megakaryocytic development of human progenitor cells cultured on two stromal cell lines and on human bone marrow stroma. Materials and Methods. Human CD34+ cells were cocultured with stromal layers in the presence of thrombopoietin. Megakaryocytes were quantified by monoclonal antibodies against glycoprotein (GP) IIb/IIIa (CD41) and GPIX (CD42a). Megakaryocytic clonogenic capacity (burst-forming unit-megakaryocyte and colony-forming unit-megakaryocyte) was determined using fibrin clot assays. Results. After 6 days, a higher percentage of megakaryocytes and more megakaryocytic colonies were recovered from the adherent cell fraction compared to the nonadherent cell fraction. In contrast, significantly more granulocytic and erythroid colonies were recovered from the nonadherent cell fraction. Repeated replating of nonadherent cells onto fresh stroma showed a decline in megakaryocytic recovery of the remaining adherent cells, pointing toward selective adhesion of megakaryocytic progenitors. This was supported further by the finding that burst-forming unit and colony-forming unit megakaryocytes were preferentially recovered from the adherent cell fraction at 24 hours. No effect of blocking the β1 integrins VLA-4 and VLA-5 on human progenitor cells was observed. A higher expression of CD42a antigen and a higher percentage of morphologically recognizable polyploid megakaryocytes were found when cells were grown in noncontact cultures compared to when grown adhered to stroma. Conclusion. In contrast to granulocytic and erythroid progenitors, both very early and more mature megakaryocytic progenitors are preferentially located in the adherent fraction in an in vitro stromal model, leading to inhibition of maturation of megakaryocytes. This suggests that the presence of stroma components in ex vivo expansion cultures, aimed at preservation and expansion of megakaryocytic progenitors, might be a prerequisite.

Costs of Peripheral Blood Progenitor Cell Transplantation Using Whole Blood Mobilised by Filgrastim as Compared With Autologous Bone Marrow Transplantation in Non-Hodgkin's Lymphoma

Objective: The aim of this paper is to compare the costs of autologous bone marrow transplantation (ABMT) and whole blood transplantation in patients with relapsed or poorly responding non-Hodgkin's lymphoma. Design and setting: In a retrospective study, we calculated the treatment costs of 40 patients who received either ABMT or, alternatively, whole blood mobilised by filgrastim (a granulocyte colony-stimulating factor. Main outcome measures and results: The recovery of granulocytes was markedly accelerated in the whole blood group as compared with the ABMT group. This resulted in a reduction in hospital costs, and costs for diagnostics and medical procedures, antibacterials, nutrition and blood transfusions. The average costs per patient in the whole blood group amounted to approximately $US16 890 as compared with approximately$US20 713 in the ABMT group (1995 values), implying a cost reduction of 18% when changing to whole blood reinfusion. Conclusions: With the premise that both therapies are equivalent, it seems that whole blood transplantation is more cost effective than ABMT.Pharmacoeconomics, Stem-cell-mobilisation, Filgrastim, Bone-marrow-transplant, Non-Hodgkin's-lymphoma, Hospitalisation, Cost-analysis, Antineoplastics, Colony-stimulating-factors

Platelet activation during haemodialysis: Comparison of cuprammonium rayon and polysulfone membranes

Background/Aim: Haemodialysis-treated patients are at a high risk of developing cardiovascular disease. Part of this risk may be attributable to the type of the dialysis membrane used. We evaluated whether different dialysis membranes differ with respect to platelet activation. Methods: In a randomized crossover trial, the platelet activation was measured in 14 patients treated with two different dialyzers (cuprammonium rayon membrane and polysulfone membrane). We compared the platelet activation over the dialyzer and between dialyzers after several weeks of dialysis. Results: There were no differences between the two dialyzers in platelet activation over the dialyzer. After 2 weeks, however, the expression of CD62P, CD63, and PAC-1 was statistically significantly lower after cuprammonium membrane treatment than after polysulfone membrane treatment (mean fluorescence intensity in arbitrary units 8.0 vs. 11.1, 2.64 vs. 4.01, and 5.61 vs. 9.74, respectively). Conclusion: Dialysis with a polysulfone membrane seems to lead to more platelet activation than dialysis with a cuprammonium membrane

Utilization of supportive care by survivors of colorectal cancer: Results from the PROFILES registry

Purpose:  In an equitable healthcare system, healthcare utilization should be predominantly explained by patient-perceived need and clinical need factors. This study aims to analyze whether predisposing, enabling, and need factors are associated with the utilization of supportive care (i.e., dietary care, oncological nursing care, physical therapy, psychological care, or participation in a rehabilitation program consisting of an exercise component and a psycho-educational component) among survivors of colorectal cancer in the Netherlands. Methods:  Cross-sectional data of 3957 survivors of colorectal cancer (1-11 years after diagnosis) were used. Clinical data from the Eindhoven Cancer Registry were linked to questionnaire data from the PROFILES registry. Regression analyses were used to examine which predisposing, enabling, and need factors were associated with self-reported utilization of supportive care. Results:  Utilization of supportive care was primarily associated with younger age, patient-perceived need (i.e., lower physical health, anxious mood, depressive mood, and fatigue), and clinical need (i.e., tumor stage, radiotherapy, chemotherapy, comorbidity, having a stoma and lower BMI) factors. Conclusions:  In the Netherlands, utilization of supportive care by survivors of colorectal cancer is primarily associated with younger age, patient-perceived need, and clinical need factors. Apart from the association with younger age, the utilization of supportive care services seems to be quite equitable. Further research is needed to determine whether there is indeed inequity in the provision of supportive care to older survivors, or whether older survivors are less in need of supportive care

Three cases of hearing impairment with surprising subjective improvements after prayer. What can we say when analyzing them?

Aim: to enhance the understanding of documented mismatches between ‘subjective’ experiences and ‘objective’ data in three cases of self-reported instantaneous healing of hearing impairment upon prayer. Method: description of three cases taken out of a larger retrospective case-based study of prayer healing in the Netherlands. In this larger study multiple reported healings were investigated using both medical files and patients’ narratives through in-depth interviews. A subset of three cases with dramatic subjective reduction of hearing impairment upon prayer was studied. These patients underwent extensive additional investigations at the audiology center of the Amsterdam University Medical Centre. All data was evaluated by an interdisciplinary medical assessment team, subsequent analysis was transdisciplinary. Results: the three case histories with self-reported healing after prayer demonstrated a clear mismatch between subjective experiences and objective findings. No measurable improvements were found in four different audiological testing methods. However, in-depth interviews, hetero-anamnesis and a validated questionnaire all confirmed the healings. The medical assessment team could not label these healings as ‘medically remarkable’ because of absence of measurable ‘objective’ changes, but they did consider them as ‘remarkable in a broader sense’. On expert consultation no equivalents of mismatches to this extent could be found. The healing experiences of our participants involved their entire being with profound positive effects in different domains of their lives, and a perception of a benevolent God who acted upon them. There was a distinctive pattern, labelled by the participants as a healing of mind, soul and body. Conclusions: The subjective-objective incongruities that were found were not well understood. We noticed a paradox: the ‘objective’ measurements did not reflect hearing abilities in daily life where-as ‘subjective experiential’ data did. The latter could be ‘objectified’ and validated in various ways. In fact, a rigid distinction between ‘objective’ and ‘subjective’ was not relevant here, nor a hierarchy among them. A model leaving room for different causations (horizontal epistemology) complied best with the multi dimensionality we came across
