Long-term Follow-up of Hematopoietic Stem Cell Transplant Survivors: A Focus on Screening, Monitoring, and Therapeutics

Patterns of follow-up care in adult blood cancer survivors-Prospective evaluation of health-related outcomes, resource use, and quality of life

BACKGROUND

Information about follow-up care in blood cancer survivors is limited. The questionnaire-based "Aftercare in Blood Cancer Survivors" (ABC) study aimed to identify patterns of follow-up care in Germany and compare different types of follow-up institutions.

METHODS

The study's 18-month prospective part compared the follow-up institutions identified in the preceding retrospective part (academic oncologists, community oncologists, primary care physicians). The questionnaires were completed by the follow-up physicians.

RESULTS

Of 1070 physicians named by 1479 blood-cancer survivors, 478 (44.7%) consented to participate. For provision of care, most oncologists relied on published guidelines, while most primary care physicians depended on information from other physicians. Survivors with a history of allogeneic transplantation or indolent lymphoma were mainly seen by academic oncologists, whereas survivors with monoclonal gammopathy, multiple myeloma, or myeloproliferative disorders were often seen by community oncologists, and survivors with a history of aggressive lymphoma or acute leukemia by primary care physicians. Detection of relapse and secondary diseases was consistently viewed as the most important follow-up goal. Follow-up visits were most extensively documented by academic oncologists (574 of 1045 survivors cared for, 54.9%), followed by community oncologists (90/231, 39.0%) and primary care physicians (51/203, 25.1%). Relapse and secondary disease detection rates and the patients' quality of life were similar at the three institutions. Laboratory tests were most often ordered by academic oncologists, and imaging by primary care physicians. Psychosocial issues and preventive care were more often addressed by primary care physicians than by oncologists.

CONCLUSIONS

Patients at high risk of relapse or late complications were preferentially treated by academic oncologists, while patients in stable condition requiring continuous monitoring were also seen by community oncologists, and patients with curable diseases in long-term remission by primary care physicians. For the latter, transfer of follow-up care from oncologists to well-informed primary care providers appears feasible.

A prospective study of the relationship between illness perception, depression, anxiety, and quality of life in hematopoietic stem cell transplant patients

AIM

The aim of study was to investigate whether depression and anxiety symptoms and illness perception prior to hematopoietic stem cell transplantation (HSCT) predict health related quality of life (HRQOL) at Day 100 and 1 year following HSCT.

METHODS

A total of 205 patients who underwent HSCT (N = 127 autologous transplants, N = 78 allogeneic transplants) were included in this prospective study. Baseline assessment was assessed prior to transplantation and post HSCT data were collected at Day 100 and 1 year. At baseline we assessed depressive symptoms (Patient Health Questionnaire-9), anxiety symptoms (Generalized Anxiety Disorder-7), illness perception (Brief Illness Perception Questionnaire), and HRQOL (Functional Assessment of Cancer Therapy-BMT).

RESULTS

Patients who expressed a greater level of concern about the severity, course, and ability to exert control over one's illness (i.e., illness perception) and who reported a greater level of depression and anxiety symptoms prior to HSCT reported lower HRQOL at both Day 100 and 1 year posttransplant, with a similar degree of association observed at the two follow-up time points.

CONCLUSIONS

Our findings suggest that pretransplant perceptions about their illness and negative mood are significant predictors of HRQOL following HSCT. Illness perception, depression, and anxiety are potentially modifiable risk factors for less than optimal outcome after HCSCT and intervention strategies should be explored.

Taste alterations in patients following hematopoietic stem cell transplantation: A qualitative study

Objective

This study aims to explore the experiences and consequences of taste alterations in patients undergoing HSCT, how they respond to these changes, and the factors that influence their responses.

Methods

In this descriptive qualitative study, face-to-face semi-structured individual interviews were conducted with 31 patients undergoing HSCT in a comprehensive hospital in Hubei, China. The interview data were transcribed and analyzed using Colaizzi's seven-step analysis. The Symptom Management Theory was applied to design the study and identify key themes.

Results

Three key themes were identified from the theory: (1) the complexity and diversity of taste experiences; (2) coping strategies; and (3) the multifaceted challenges of coping. Taste alterations in HSCT patients were characterized by diversity and dynamism. Patients employed three distinct coping styles in response to taste alterations: active coping, reluctant submission, and passive coping. These coping styles were influenced by various factors, including the specific treatment modalities of HSCT, individual patient characteristics, and the healthcare environment.

Conclusions

The experience of taste alterations among HSCT patients is intricate and varied, and the importance of addressing this symptom can easily be underestimated. Management of taste alterations is influenced by multiple factors. Nursing staff should give careful attention to taste alterations in HSCT survivors, enhance their expertise in managing taste alterations, provide robust health education, conduct regular screening and assessments, and formulate individualized intervention plans to assist patients in actively and effectively managing taste alterations.

Preventive health care in blood cancer survivors: results from the ABC study

BACKGROUND

Blood cancer survivors are at increased risk for second primary malignancies, cardiovascular diseases, and infections. Little is known about preventive care in blood cancer survivors.

METHODS

Our questionnaire-based study included blood cancer patients diagnosed at the University Hospital of Essen before 2010, with a ≥ 3-year interval from the last intense treatment. One section of the retrospective study covered preventive care (cancer screening, cardiovascular screening, vaccination).

RESULTS

Preventive care was delivered by a general practitioner for 1100 of 1504 responding survivors (73.1%), by an oncologist for 125 (8.3%), by a general practitioner together with an oncologist for 156 (10.4%), and by other disciplines for 123 (8.2%). Cancer screening was more consistently performed by general practitioners than by oncologists. The converse was true for vaccination, with particularly high vaccination rates in allogeneic transplant recipients. Cardiovascular screening did not differ between care providers. Cancer and cardiovascular screening rates in survivors eligible for statutory prevention programs were higher than in the general population (skin cancer screening 71.1%; fecal occult blood testing 70.4%; colonoscopy 64.6%; clinical breast examination 92.1%; mammography 86.8%; cervical smear 86.0%; digital rectal examination 61.9%; blood pressure test 69.4%; urine glucose test 54.4%; blood lipid test 76.7%; information about overweight 71.0%). The Streptococcus pneumoniae vaccination rate was higher (37.0%) and the influenza vaccination rate was lower (57.0%) than in the general population.

CONCLUSIONS

Utilization of preventive care is high among German blood cancer survivors. To ensure widespread delivery and avoid redundancy, communication between oncologists and preventive care providers is essential.

Feasibility of a new model of care for allogeneic stem cell transplantation recipients facilitated by eHealth: The MY-Medula pilot study

BACKGROUND

The use of allogeneic stem cell transplantation (allo-SCT) for the treatment of hematologic diseases is steadily increasing. However, allo-SCT has the downside of causing considerable treatment-related morbidity and mortality. Mobile technology applied to healthcare (mHealth) has proven to be a cost-effective strategy to improve care and offer new services to people with multimorbidity, but there are few data on its usefulness in allo-SCT recipients.

OBJECTIVE

The aim of this report was to describe a new integrated healthcare model facilitated by an mHealth platform, named EMMASalud-MY-Medula, and to report the results of a le.

STUDY DESIGN

The MY-Medula platform development approach consisted of 4 phases. Firstly, patient and healthcare professional needs were identified and technological development and pre-testing tests were conducted (phases 1-3, January 2016-March 2021). Then, a non-randomized, prospective, observational, single-center pilot study was conducted (October 2021-January 2022) at the adult Stem Cell Transplant Unit of a tertiary university hospital.

RESULTS

Twenty-eight volunteer allo-SCT recipients were included in the pilot study. Fifty percent were outpatients in the first-year post-SCT and the remaining 50% were affected by steroid-dependent graft-versus-host disease (SR-GVHD). All patients used MY-Medula application during the two-month follow-up period with a median number of visits to the application of 143 (range 6-477). A total of 2067 self-monitoring records were made, and 205 text messages were received, most of them related to symptoms description (47%) and doubts about medication (21%). In 3.4% of the cases drug dose adjustments were performed by the pharmacist because of dosing errors or interactions. At the end of the study, a 6-question Likert-type questionnaire for patients and a 22-question test for healthcare professionals showed a high degree of satisfaction (95% and 100% respectively) with the new healthcare pathway.

CONCLUSIONS

Re-engineering allo-SCT recipients follow-up into an integrated, multidisciplinary model of care facilitated by mHealth tools is feasible and has been associated with a high usability and degree of satisfaction by patients and healthcare professionals. A randomized trial aiming to determine the cost-effectiveness of MY-Medula-based follow-up post-SCT is currently enrolling participants.

Multicenter prospective validation study for international chronic ocular graft-versus-host disease consensus diagnostic criteria

PURPOSE

To validate the international chronic ocular graft-versus-host disease (GVHD) diagnostic criteria (ICCGVHD) compared to the National Institute of Health diagnostic criteria 2014 (NIH2014) for chronic ocular GVHD.

METHODS

Between 2013 and 2019, the study enrolled 233 patients with or without chronic ocular GVHD combined with the presence or absence of systemic chronic GVHD in an internationally prospective multicenter and observational cohort from 9 institutions. All patients were evaluated for four clinical parameters of ICCGVHD.

RESULTS

The relation between the ICCGVHD score (0-11) and NIH2014 eye score (0-4) was relatively high (r = 0.708, 95% CI: 0.637-0.767, p < 0.001). The sensitivity and specificity of ICCGVHD for NIH 2014 for 233 patients were 94.3% (95% CI: 89.6%-98.1%) and 71.7% (95% CI: 63.0-79.5%), respectively (cutoff value of the ICCGVHD score = 6). The positive predictive value was 77.1% (95% CI: 71.1%-82.1%), and the negative predictive value was 87.0% (95% CI:81.6-92.5%). For the patients with systemic GVHD (n = 171), the sensitivity and specificity were 94.2% and 67.2%, respectively (ICCGVHD-score cutoff value = 6). By receiver operating characteristic (ROC) curve analysis, the area under the curve (AUC) was 0.903 (95% CI: 0.859-0.948). For patients without systemic GVHD (n = 62), the sensitivity and specificity were 100% and 76.7%, respectively (ICCGVHD-score cutoff value = 6). The AUC was 0.891 (95% CI 0.673-1.000).

CONCLUSIONS

Good sensitivity, specificity, predictive value and correlation were found between ICCGVHD and NIH2014. ICCGVHD scores ≥6 can be useful to diagnose ocular GVHD with or without systemic GVHD for clinical research.

Evaluation of Kidneys’ Functional State in Acute Lymphoblastic Leukemia Patients Following Hematopoietic Stem Cell Transplantation

BACKGROUND: Hematopoietic Stem Cell Transplantation (HSCT) has recently been a widely used method of therapy in various fields of current medicine, particularly in hematology.Some patients develop renal disorders following HSCT. AIM: This study aims to evaluate the dynamics of changes in the functional state of the kidneys in patients with ALL after HSCT. METHODS: In the period from 2015 to 2021, for the first time in Kazakhstan, patients with acute lymphoblastic leukemia (ALL) who underwent allogeneic and haploidentical HSCT were prospectively examined. RESULTS: We determined that the greatest decrease in glomerular filtration rate occurred in the group of patients who underwent haploidentical bone marrow transplantation. Moreover, we believe that our results are related to known contributing risk factors, such as the type of performed transplantation and the duration of taking medications for the prevention of graft versus host disease. Our results also indicate that the lethal outcome in the group with haploidentical HSCT in the studied patients with ALL was greater than in the group with allogeneic HSCT. CONCLUSION: In conclusion, a decrease in kidney function in patients who have survived HSCT is probably a common complication; however, further prospective studies are required to confirm these results to develop additional algorithms for the treatment and prevention of renal disorders in patients with acute leukemia after HSCT.

Feasibility and usefulness of recommended screenings at long-term follow-up clinics for hematopoietic cell transplant survivors

PURPOSE

Advances in allogeneic hematopoietic cell transplantation (allo-HCT) have resulted in a growing number of transplant survivors; however, long-term survivors are at risk of developing late complications, and published guidelines recommend screening of this population. We conducted a single-center prospective study to evaluate the adherence to and usefulness of recommended screenings at a long-term follow-up (LTFU) clinic.

METHODS

We included consecutive patients who received allo-HCT at our center from 2014, as well as post-HCT patients visiting our outpatient clinic. Visits and screenings were planned at 3 months, 6 months, and 1 year after allo-HCT, and annually thereafter. Outcomes were reported by physicians including the incidence of findings at each screening that led to interventions.

RESULTS

Among the 216 participants, 95% visited the LTFU clinic, and 94% completed planned screenings. However, the rate of secondary cancer screenings targeting high-risk subjects was lower (38% to 68%). The overall percentage of screening results leading to interventions was 4.5%, with higher percentages (> 10%) for bone density testing, ophthalmological examinations, dental assessment, upper gastrointestinal endoscopy, and colonoscopy, with two patients diagnosed with secondary cancers.

CONCLUSIONS

Although the overall screening rate was high, it should be possible to improve the detection rate of late complications by decreasing screening failures, especially the screening for secondary cancers limited for high-risk survivors. A nationwide effort to educate HCT survivors and health practitioners using standardized nationwide LTFU tools may be effective, along with the development of institutional, local, and nationwide networks to maintain effective follow-up systems.
