Medical nutrition therapy during intensive remission-induction treatment and hematopoietic stem cell transplantation in acute myeloid leukemia patients: Hematologists' experiences and perspectives.

BACKGROUND & AIMS: The European Societies for Clinical Nutrition and Metabolism (ESPEN) and Blood and Marrow Transplantation (EBMT) recommend enteral nutrition (EN) as the first-choice medical nutrition therapy in acute myeloid leukemia (AML) patients undergoing intensive treatments, including high-dose remission-induction chemotherapy and hematopoietic stem cell transplantation (HSCT). However, parenteral nutrition (PN) remains the preferred method of nutrition support in current clinical practice. The aim of this qualitative study was to gain insight into hematologists' experiences and perspectives regarding the choice and ESPEN/EBMT recommendations on EN versus PN. METHODS: Online semi-structured interviews were conducted with one hematologist from each of the 21 hospitals offering intensive AML treatments in the Netherlands, using Microsoft Teams. Interviews were audio-recorded, transcribed verbatim and thematically analyzed using Atlas. ti. One hundred nineteen hematologists working in the same hospitals were invited to complete a short online questionnaire survey (SurveyMonkey®) regarding their knowledge and opinion on the ESPEN/EBMT guidelines recommending EN over PN during intensive AML treatments. The results of this survey are presented in a descriptive way. RESULTS: Fifty-nine hematologists participated in this study (42% overall response rate), of which 21 in the semi-structured interviews (response rate 100%) and 38 in the online survey (response rate 32%). Hematologists considered medical nutrition therapy important for prevention and treatment of malnutrition and associated adverse outcomes in AML patients undergoing intensive remission-induction treatment and HSCT. However, opposed to the ESPEN/EBMT guidelines, the vast majority of hematologists were hesitant or reluctant to use EN instead of PN as the first-choice medical nutrition therapy in these patients. The most frequently cited barriers to use EN were the expected low feasibility and tolerance of EN, feeding tube-related discomfort and bleeding risk, and patient refusal. Other barriers to follow the guidelines on EN were related to personal factors, including hematologists' knowledge (lack of awareness and familiarity) and attitude (lack of agreement, outcome expectancy, experience, success, motivation, and learning culture), guideline-related factors (lack of evidence and applicability), and external factors (lack of collaboration and resources). Facilitators included strategies for nutrition education and dissemination of nutritional guidelines, interprofessional and patient collaboration, availability of feeding tubes that can be inserted without endoscopy and stronger scientific evidence. CONCLUSIONS: Hematologists recognized the importance of medical nutrition therapy for reducing malnutrition and related negative outcomes during intensive AML treatments. However, contrary to the ESPEN/EBMT guidelines, they preferred PN instead of EN as the medical nutrition therapy of first choice. To reduce compliance barriers, interventions should focus on improving hematologists' knowledge of medical nutrition therapy and dietary guidelines, enhancing success rates of EN by adequately triaging patients eligible for EN and inserting duodenal feeding tubes using an electromagnetic sensing device without endoscopy, developing decision aids and multidisciplinary guidelines and care pathways. Furthermore, future trials should focus on the feasibility and benefits of EN versus PN both during remission-induction treatment and HSCT.

Nutrition-related problems, nutritional support practices and barriers to adherence to nutritional guidelines during intensive treatment for acute myeloid leukemia: Patients' and hematology nurses' perspectives and experiences.

BACKGROUND & AIMS: The updated guidelines of the European Society for Clinical Nutrition and Metabolism (ESPEN) and for Blood and Marrow Transplantation (EBMT) on nutrition in intensively treated acute myeloid leukemia (AML) patients recommend enteral nutrition (EN) instead of parenteral nutrition (PN) as the first-choice medical nutrition therapy. Despite this, PN remains the preferred route of nutrition administration in daily practice. The aim of this qualitative study was to gain insight into the patients' and hematology nurses' experiences and perceptions regarding nutritional problems and nutritional support and the reasons for the low adherence to the ESPEN/EBMT guidelines. METHODS: Semi-structured interviews were conducted in 23 patients from various Dutch hospitals who had completed intensive AML treatment. Interviews with 22 patients were audio-recorded and transcribed, one interview was summarized. The transcripts and summary were thematically analyzed using Atlas.ti. From each of the 22 Dutch hospitals providing intensive AML treatment, one hematology nurse participated in a telephone questionnaire survey. The results of this survey are presented in a descriptive way. RESULTS: Nutritional problems were a major source of distress in most participating patients. Nutritional support often led to peace of mind and less concerns, provided that there were no conflicting nutritional support practices among treating hospitals. Patients perceived PN and EN as a life-line and necessary for the prevention of or recovery from physical decline, but they also experienced loss of independence, limited mobility, fear of unwanted body weight gain and problems related to the feeding equipment. Both patients and hematology nurses regarded PN as an easy method of nutrition administration, while EN was often seen as a necessary evil or was even refused by patients, owing to tube-related physical discomfort and EN intolerance. Both patients' and hematology nurses' reluctance to administer EN proved to be barriers to the ESPEN/EBMT nutritional guideline adherence. Among the surveyed hematology nurses, barriers to adherence included personal factors related to their knowledge (lack of awareness) and attitudes (negative outcome expectancy and lack of agreement), guideline-related factors (lack of evidence) and external factors (lack of collaboration). CONCLUSION: Individualized nutritional support, including EN and PN, may reduce nutrition-related distress in intensively treated AML patients, provided that conflicting nutritional support practices among hospitals are avoided or explained. The barriers to adherence to the ESPEN/EBMT guidelines on EN and PN in this patient group may be reduced by enhancing hematology nurses' awareness and knowledge of the guidelines, incorporating the guidelines into multidisciplinary clinical pathways, improving outcome of EN by proper triage of patients eligible for EN and increasing the level of evidence of the guidelines.

Adherence to guidelines on nutrition support during intensive treatment of acute myeloid leukemia patients: A nationwide comparison.

BACKGROUND & AIMS: The level of adherence to the updated guidelines of The European Societies for Clinical Nutrition and Metabolism (ESPEN) and for Blood and Marrow Transplantation (EBMT) on nutrition in intensively treated adult acute myeloid leukemia (AML) patients in clinical practice is unknown. The aim of this nationwide survey was to investigate ESPEN/EBMT nutritional guideline adherence during intensive AML treatment, variation in nutrition support practices among hospitals and whether these practices changed after guideline publication. METHODS: All 22 Dutch hospitals providing (aftercare following) high-dose chemotherapy and/or hematopoietic stem cell transplantation for adult AML patients were surveyed on nutrition support practices during these intensive AML treatments. We used an online questionnaire in 2015 and semi-structured telephone interviews in 2018-2019. Both surveys were completed by registered dieticians and addressed the use of enteral (EN) and parenteral (PN) nutrition. The ESPEN/EBMT nutritional guideline adherence was investigated through the telephone interviews. RESULTS: High-level ESPEN/EBMT guideline adherence and/or uniformity among hospitals regarding nutrition support practices during intensive AML treatment were observed for nutritional screening, -aims, safe food handling and exercise training. Adherence to ESPEN/EBMT recommendations that were not implemented into national guidelines, including nutritional assessment and use of medical nutrition, was poor. All hospitals assessed nutritional intake, -impact symptoms and body weight, but muscle mass, physical performance and degree of systemic inflammation were rarely and variably monitored. Although the number of hospitals using EN as first-choice nutritional intervention increased from 3 hospitals in 2015 to 8 in 2019, PN remained the preferred method of nutrition support. Furthermore, the timing of medical nutrition varied. CONCLUSIONS: Although the use of EN increased after publication of the updated ESPEN/EBMT nutritional guidelines, adherence to these standards was limited and there was heterogeneity in nutrition support practices during intensive AML treatment among hospitals. Incorporating international nutritional standards into national guidelines by nutrition expert groups immediately upon publication may improve adherence.

Changes in body weight and serum liver tests associated with parenteral nutrition compared with no parenteral nutrition in patients with acute myeloid leukemia during remission induction treatment.

PURPOSE: Differences in body weight changes and serum liver tests (LTs) in acute myeloid leukemia (AML) patients receiving parenteral nutrition (PN) versus no PN during remission induction (RI) treatment were assessed. METHODS: Retrospectively, differences in body weight changes and serum LTs in AML patients (n = 213) who received PN versus no PN during RI treatment in one of three Dutch hospitals between 2004 and 2015 were assessed. Weekly body weight and serum LT registrations were collected from medical records. Patients' body weight changes were compared between the hospitals where PN is applied upon first indication of inadequate oral intake (PN hospitals) and the hospital where use of PN is limited to severe cases only (no-PN hospital) using repeated measures mixed model analysis. Differences in severity of serum LT elevations, according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0, were assessed between patients who did and did not receive PN using chi-square or Fisher's exact tests, and multiple logistic regression analysis. RESULTS: Compared with patients of the PN hospitals, patients of the no-PN hospital experienced significantly more body weight loss during RI treatment (between-group difference 7.2%, 95% CI 4.0-10.3%). Furthermore, PN was associated with transient mild to moderate elevations of liver enzymes, but not with raised median total bilirubin levels nor with occurrence of CTCAE grade 3-4 LT elevations. CONCLUSION: Frequent compared with exceptional use of PN in AML patients during RI treatment better preserved body weight, without clinically relevant (CTCAE grade 3-4) elevations in serum LTs.

Autologous transplantation versus allogeneic transplantation in patients with follicular lymphoma experiencing early treatment failure.

BACKGROUND: Early treatment failure (ETF) in follicular lymphoma (FL), defined as relapse or progression within 2 years of frontline chemoimmunotherapy, is a newly recognized marker of poor survival and identifies a high-risk group of patients with an expected 5-year overall survival (OS) rate of approximately 50%. Transplantation is an established option for relapsed FL, but its efficacy in this specific ETF FL population has not been previously evaluated. METHODS: This study compared autologous hematopoietic stem cell transplantation (auto-HCT) with either matched sibling donor (MSD) or matched unrelated donor (MUD) allogeneic hematopoietic cell transplantation (allo-HCT) as the first transplantation approach for patients with ETF FL (age ≥ 18 years) undergoing auto-HCT or allo-HCT between 2002 and 2014. The primary endpoint was OS. The secondary endpoints were progression-free survival, relapse, and nonrelapse mortality (NRM). RESULTS: Four hundred forty FL patients had ETF (auto-HCT, 240; MSD hematopoietic stem cell transplantation [HCT], 105; and MUD HCT, 95). With a median follow-up of 69 to 73 months, the adjusted probability of 5-year OS was significantly higher after auto-HCT (70%) or MSD HCT (73%) versus MUD HCT (49%; P = .0008). The 5-year adjusted probability of NRM was significantly lower for auto-HCT (5%) versus MSD (17%) or MUD HCT (33%; P < .0001). The 5-year adjusted probability of disease relapse was lower with MSD (31%) or MUD HCT (23%) versus auto-HCT (58%; P < .0001). CONCLUSIONS: Patients with high-risk FL, as defined by ETF, undergoing auto-HCT for FL have low NRM and a promising 5-year OS rate (70%). MSD HCT has lower relapse rates than auto-HCT but similar OS.

[Results of a study on fatigue in breast cancer patients receiving adjuvant chemotherapy: the first four days after treatment are the worst]. / Ergebnisse einer Untersuchung von Fatigue bei Brustkrebspatientinnen mit adjuvanter Chemotherapie: Die ersten vier Tage nach dem Zyklus sind am belastendsten.

A large number of breast cancer patients receiving adjuvant chemotherapy is suffering from fatigue. Until now there has been a lack of knowledge concerning the course of fatigue in breast cancer patients between two cycles of adjuvant chemotherapy. Therefore a prospective cohort study was conducted including 151 breast cancer patients from six hospitals in The Netherlands. The object of the study was to investigate the course of fatigue between the third and the fourth cycles of adjuvant chemotherapy, and to prove whether that course is influenced by different chemotherapy schedules. The patients were treated either with a doxorubicin containing schedule (21 or 28 days) or with a combination of cyclophosphamide, methotrexate, and 5-fluorouracil (CMF, 28 days). To assess fatigue patients were asked to write a diary cotaining the Shortened Fatigue Questionnaire (SFQ) from the beginning of the third cycle to the start of the fourth one. All days after completion of the third chemotherapy treatment were analysed. The main hypothesis to be tested was that the maximum fatigue level occurs in the first four days after treatment. Results revealed a chaotic pattern of fatigue between both cycles of chemotherapy in each of the treatment group. Smooth (splines) curves showed an average highest level of fatigue on day 3 post treatment. For the regimens with 28-days-intervalls another peak of fatigue was registered on day 11. A significant larger number of patients experienced maximum fatigue levels before day 5. The course of fatigue in the CMF group was significantly different compared with both doxorubicin groups. Women of the CMF group experienced lower fatigue peaks than patients of other groups. The results confirm the main hypothesis. The first days after treatment with chemotherapy are the worst ones for breast cancer patients. The course of fatigue is significantly related to the type of chemotherapy. Knowing these effects patients can better prepare oneself and their daily living for the time of adjuvant chemotherapy.
