Predictors of post traumatic growth in allogeneic hematopoietic stem cell transplantation survivors: a cross-sectional survey.

AIMS: Given the increasing number of Hematopoietic Stem Cell Transplantations (HSCT) performed world-wide, the increasing likelihood of survival following HSCT, and the profound physical, psychosocial, and emotional impact of HSCT on survivors, their carers and families, it is important to identify factors that may contribute to or support post-traumatic growth (PTG) after transplant. In this study, we aimed to investigate the prevalence of PTG in an Australian cohort of long-term allogeneic HSCT survivors and describe associations between PTG and relevant clinical, sociodemographic and psychological variables. METHODS: This was a large, multi-centre, cross sectional survey of Australian HSCT-survivors inviting all those transplanted in New South Wales between 2000 and 2012. Respondents completed the PTG Inventory (PTGI), the Sydney Post-BMT Survey, FACT-BMT, DASS 21, The Chronic Graft versus Host Disease (GVHD) Activity Assessment-Patient Self-Report (Form B), the Lee Chronic GVHD Symptom Scale, and the Fear of Cancer Recurrence Scale. Data was analysed using independent t-tests, one-way analysis of variance, and pearson's correlations, and hierarchical multiple regression adjusted for potential confounders and to ascertain independent associations of explanatory variables with PTG. RESULTS: Of 441 respondents, 99% reported some level of PTG with 67% reporting moderate to high levels of PTG. Female gender, younger age, complementary therapy use, anxiety, psychological distress and psychosocial care, and higher quality of life were associated with higher levels of PTG. Importantly, we also found that PTG was not associated with either chronic GVHD or post-HSCT morbidity. CONCLUSIONS: In this study - the largest study of PTG in long-term allogeneic HSCT survivors - we found that growth appears ubiquitous, with 99% of survivors reporting some degree of PTG and 67% reporting moderate-high levels of PTG. Importantly, we found no association with GVHD or chronic physical post-HSCT morbidity, or adverse financial, occupational or sexual impacts. This suggests that it is the necessity for and experience of, HSCT itself that foments personal growth. Accordingly, healthcare professionals should be alert to the profound and wide-ranging impact of HSCT - and the degree to which survivor's may experience PTG. Identifying interventions that may assist HSCT survivors cope and building their resilience is of utmost importance.

Decisional Regret in Long-Term Australian Allogeneic Hematopoietic Stem Cell Transplantation Survivors: A Cross-Sectional Survey.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an intensive but effective treatment for malignant and non-malignant diseases. However, long-term survival often comes at a cost, with survivors experiencing chronic morbidity and are at risk of relapse and secondary malignancy. This study aimed to describe decisional regret in a large cohort of Australian long-term allo-HSCT survivors. A cross-sectional survey was conducted with 441 adults in New South Wales, assessing quality of life (QoL), psychological, social, demographic, and clinical variables. Less than 10% of survivors expressed regret, with chronic graft-versus-host disease being the most important clinical factor. Psycho-socioeconomic factors such as depression, lower QoL scores, lower household income, higher treatment burden, and not resuming sex post-HSCT were also associated with regret. Findings highlight the need for valid informed consent and ongoing follow-up and support for allo-HSCT survivors dealing with life post-transplant. Nurses and healthcare professionals play a critical role in addressing decisional regret in these patients.

Incidence of Sinusoidal Obstruction Syndrome/Veno-Occlusive Disease and Treatment with Defibrotide in Allogeneic Transplantation: A Multicenter Australasian Registry Study.

Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is an established complication in patients undergoing allogeneic hemopoietic stem cell transplantation (HSCT). Defibrotide is an effective and safe pharmacologic option for treating diagnosed SOS/VOD. By exploring data provided to the Australasian Bone Marrow Transplant Recipient Registry (ABMTRR) by centers in Australia and New Zealand, this study aimed to describe the incidence of SOS/VOD and patterns of defibrotide use from 2016 to 2020. Patients who underwent allogeneic hemopoietic stem cell transplantation between 2016 and 2020 were identified from the ABMTRR. Data were extracted for a total of 3346 patients, 2692 from adult centers and 654 from pediatric centers, with a median follow-up of 21.5 months and 33.3 months, respectively. Descriptive statistics were used to describe the patient population, including the incidence of SOS/VOD and defibrotide use. Comparisons were made between patients without SOS/VOD and those with SOS/VOD, divided into defibrotide and no defibrotide cohorts. Associations with overall survival (OS) and day 100 survival with such variables as sex, age, disease at transplantation, stem cell source, conditioning agents, SOS/VOD diagnosis, and use of defibrotide, were determined. The reported incidence of SOS/VOD was 4.1% in adult centers and 11.5% in pediatric centers. Defibrotide was administered to 74.8% of adult patients and 97.3% of pediatric patients with SOS/VOD. Significant variability in the use, dosage, and duration of defibrotide was seen across the adult centers. The day 100 survival rate and median OS for patients managed with defibrotide was 51.8% and 103 days, respectively, for adult patients and 90.4% and not reached, respectively, for pediatric patients. In adults, older age at transplantation, an HLA-matched nonsibling relative donor, and a diagnosis of SOS/VOD treated with defibrotide were associated with reduced OS. In pediatric patients, the patient and transplantation characteristics associated with reduced OS were a diagnosis of SOS/VOD and a ≥2 HLA-mismatched related donor. A collaborative approach across Australasia to diagnosing and managing SOS/VOD, particularly with respect to consistent defibrotide use, is recommended.

Long-term treatment burden following allogeneic blood and marrow transplantation in NSW, Australia: a cross-sectional survey.

BACKGROUND: Allogenic blood and marrow transplant (allo-BMT) is an arduous treatment used increasingly for many life-threatening conditions. Recognition of the profound impacts of the long term and late effects is ever-growing, as is the healthcare workload (treatment burden) of survivorship. PURPOSE: To quantify the treatment burden of long-term survival following allo-BMT, regarding the range of health services, therapies and investigations accessed by survivors. METHODS: A large, multi-centre cross-sectional survey of adult allo-BMT survivors transplanted between 2000 and 2012 in Sydney, Australia. Participants completed six validated instruments and one purposed designed for the study, the Sydney Post BMT Study (SPBS), answering questions relating to medication use, medical treatments, referrals, assessments and frequency of hospital/clinic attendance. RESULTS: Of the 441 allo-BMT survivors, over a quarter who were more than 2 years post BMT attended the hospital clinic at least monthly, and 26.7% required a number of regular medical procedures (e.g. venesection, extracorpororeal photopheresis). Specialist medical and allied health referral was very common, and compliance with internationally recommended long-term follow-up (LTFU) care was suboptimal and decreased as time from BMT increased. CONCLUSION: Respondents reported a large medication (conventional and complementary), screening, assessment and health care burden. IMPLICATIONS FOR CANCER SURVIVORS: Treatment burden contributes significantly to the 'workload' of survivorship and can have a severe and negative impact on BMT survivors, carers and the healthcare system-making it difficult to comply with optimal care. Clinicians must be primed with skills to identify survivors who are overburdened by the health care required for survival and develop strategies to help ease the burden.

Predictors of quality of life in allogeneic hematopoietic stem cell transplantation survivors.

OBJECTIVES: To establish the demographic, medical, transplant, and lifestyle factors that impact Quality of Life (QoL) in long-term survivors of allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT). DESIGN: Cross-sectional study utilizing self-report measures. SAMPLE/METHODS: In this cross-sectional study of 441 adult survivors of allo-HSCT, participants completed questionnaires assessing QoL, psychological, social, demographic, and clinical variables. FINDINGS: Factors associated with improved QoL post-allo-HSCT included time since transplant, female gender, attendance at outpatient appointments, health screening uptake, exercise, and resumption of travel. Factors significantly associated with impaired QoL included chronic morbidities (GVHD), taking psychotropic medication, failure to resume sexual activity (in men), male gender, psychological distress, low income or decline in work status, transition to non-physical work, and necessity for post-allo-HSCT care from various health professionals. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Identification of survivors more likely to experience a reduced QoL following allo-HSCT may enable the targeting of health services to the most vulnerable, and the development of interventions and resources. The data from this study led to the development of HSCT Long-Term Follow Up Clinical Guidelines in New South Wales.

Fear of cancer recurrence following allogeneic haematopoietic stem cell transplantation (HSCT) for haematological malignancy: A cross-sectional study.

PURPOSE: The aim of this study was to quantify the prevalence of Fear of Cancer Recurrence (FCR) in patients with a prior haematology malignancy surviving more than one year post allogeneic haematopoietic stem cell transplantation (HSCT), and to identify the demographic, medical and psychological factors associated with FCR occurrence. METHOD: Participants were adult allogeneic HSCT recipients who had undergone the procedure for acute leukaemia or other haematological malignancy between the years 2000-2012 in Sydney, Australia. They completed a purpose designed survey and six other validated instruments which assessed FCR, psychological functioning, quality of life, demographic, social and clinical variables. RESULTS: Of the 364 respondents, approximately 11% of the sample lived with severe FCR while only 5% of subjects reported having no FCR. Variables significantly associated with higher FCR included unemployment, a shorter time (years) post-transplant, not attending to health screening (PAP smear), a secondary diagnosis of skin cancer, younger age, referral to a psychiatrist and taking psychotropic medication. Higher psychological distress (depression, anxiety, stress) and lower quality of life made a significant contribution to the prediction of FCR. CONCLUSIONS: Post HSCT follow-up care should include an assessment and discussion regarding FCR to balance both realistic and unrealistic cancer recurrence risks. Managing FCR is one of the most ubiquitous unmet needs of survivors of haematological disease and it is important that HSCT nurses are both aware of the fear, and are equipped with knowledge on how to help patients navigate it with realistic expectations.

Outpatient rituximab, ifosfamide, etoposide (R-IE) in patients older than 60 years with relapsed or refractory diffuse large B-cell lymphoma who are not candidates for stem cell transplantation.

Patients with relapsed-refractory diffuse large B-cell lymphoma (RR-DLBCL) ineligible for autologous stem cell transplantation (autoSCT) have poor survival. Thirty transplant-ineligible patients older than 60 years were administered rituximab 375 mg/m2 day 1, ifosfamide 1333 mg/m2 days 1 to 3, and etoposide 80 mg/m2 days 1 to 3 (R-IE) every 21 days for 6 cycles plus 2 doses of rituximab. Revised international prognostic index 3-4 was seen in 53% and prior rituximab exposure in 60%. The complete and overall response rates were 55% and 76%, respectively. Median progression free survival (PFS) and overall survival were 23 and 24 months, respectively. Patients relapsing within 12 months of prior treatment had a median PFS of 2.5 months compared to 23 months for those relapsing beyond 12 months. Grade 3-4 thrombocytopenia and neutropenia occurred in one and eight patients, respectively. R-IE is an effective, well tolerated regimen in RR-DLBCL patients not fit for autoSCT.

Pre- and post-bone marrow harvest anaemia is associated with lower CD34+ stem cell collection, high harvest volume and female gender.

BACKGROUND: Donor safety is paramount when performing bone marrow stem cell harvest. The incidence of full blood count (FBC) abnormalities among donors and variables associated with anaemia after marrow harvest are not well established. AIMS: To describe the frequency of FBC abnormalities prior to bone marrow stem cell harvest and to identify variables associated with post harvest anaemia. METHODS: Outcomes of 80 consecutive adult marrow harvests performed at our centre were analysed retrospectively. RESULTS: FBC abnormalities were present in 28% of donors prior to marrow harvest with normocytic anaemia the most common abnormality in 13%. Reduced donor haemoglobin (Hb) was independently correlated with lower CD34+ cell count per kg of recipient body weight. Anaemia (Hb < 100 g/L) was seen in 20% of donors after harvest with median decrease in Hb of 19 g/L. Variables independently associated with anaemia after harvest included donor to recipient weight ratio (P = 0.011), high collection volume (P = 0.044) and female gender (P = 0.023). Total nucleated cell and CD34 concentration in the final collected product were associated with the inverse of harvested marrow volume (P < 0.001). CONCLUSIONS: Pre-harvest anaemia should be corrected where possible particularly in female donors. Marrow collection volume should be minimised to reduce post-harvest anaemia, optimise CD34+ cell number and improve nucleated and stem cell concentrations in the harvest product.

A survey of infectious diseases and vaccination uptake in long-term hematopoietic stem cell transplant survivors in Australia.

BACKGROUND: This cross-sectional survey aimed to establish the prevalence of infectious diseases and vaccination uptake in long-term allogeneic hematopoietic stem cell transplants (HSCT) survivors in New South Wales, in order to reduce long-term post-HSCT morbidity and mortality and enhance long-term care. PATIENTS AND METHODS: Hematopoietic stem cell transplants survivors aged over 18 years and transplanted between 2000-2012 in New South Wales (NSW) were eligible to participate. Survivors self-completed the Sydney Post BMT Study survey, FACT-BMT (V4), Chronic Graft versus Host Disease (cGVHD) Activity Assessment Self Report, Lee Chronic GvHD Symptom Scale, DASS21, Post Traumatic Growth Inventory, and the Fear of Recurrence Scale. RESULTS: Of the 583 HSCT survivors contacted, 441 (78%) completed the survey. Respondents included 250 (57%) males and median age was 54 years (range 19-79 years). The median age at the time of transplant was 49 years (Range: 17-71), the median time since HSCT was 5 years (Range: 1-14) and 69% had cGVHD. Collectively, 41.7% of survivors reported a vaccine preventable disease (VPD) with the most common being influenza-like-illness (38.4%), varicella zoster/shingles (27.9%), pap smear abnormalities (9.8%), pneumococcal disease (5.1%), and varicella zoster (chicken pox) (4.6%). Only 31.8% had received the full post-HSCT vaccination schedule, and the majority (69.8%) of these had received the vaccines via their General Practitioner. cGVHD was not found to be a significant factor on multivariate analysis for those who were vaccinated. There was a trend toward lower vaccination rates in patients in a lower income strata. CONCLUSIONS: Vaccinating post-HSCT survivors to prevent infections and their consequences have an established role in post-HSCT care. Improving rates of post-HSCT vaccination should be a major priority for BMT units.

Rescue haploidentical peripheral blood stem cell transplantation for engraftment failure: a single-centre case series.

Graft failure affects approximately 5% of allogeneic stem cell transplants, with a poor prognosis. Salvage second allogeneic stem cell transplantation (alloSCT2) is limited by high rates of transplant-related mortality from infection and graft-versus-host disease. We report on five adult patients receiving rescue alloSCT2 using haploidentical peripheral blood stem cells. All patients achieved neutrophil engraftment, two subsequently died from sepsis and disease relapse, respectively. Three patients remain alive up to 2 years post-transplant. We suggest consideration of haploidentical alloSCT2 for patients with graft failure.

Haematopoietic stem cell transplantation survivorship and quality of life: is it a small world after all?

PURPOSE: The aim of this qualitative study was to gain a rich understanding of the impact that haematopoietic stem cell transplantation (HSCT) has on long-term survivor's quality of life (QoL). METHOD: Participants included 441 survivors who had undergone HSCT for a malignant or non-malignant disease. Data were obtained by a questionnaire positing a single open-ended question asking respondents to list the three issues of greatest importance to their QoL in survivorship. Responses were analysed and organised into QoL themes and subthemes. RESULTS: Major themes identified included the following: the failing body and diminished physical effectiveness, the changed mind, the loss of social connectedness, the loss of the functional self and the patient for life. Each of these themes manifests different ways in which HSCT survivor's world and opportunities had diminished compared to the unhindered and expansive life that they enjoyed prior to the onset of disease and subsequent HSCT. CONCLUSIONS: HSCT has a profound and pervasive impact on the life of survivors-reducing their horizons and shrinking various parts of their worlds. While HSCT survivors can describe the ways in which their life has changed, many of their fears, anxieties, regrets and concerns are existential in nature and are ill-defined-making it exceeding unlikely that they would be adequately captured by standard psychometric measures of QoL post HSCT.

Nutritional issues and body weight in long-term survivors of allogeneic blood and marrow transplant (BMT) in NSW Australia.

PURPOSE: The aims of this study were to describe the long-term nutrition, body weight and body image issues facing survivors of Allogeneic Blood and Marrow Transplant (BMT) and their impact on quality of life. It also describes survivors' perception of enteral feeding during BMT. METHODS: Four hundred and forty-one survivors who had undergone a BMT in NSW, Australia between 2000 and 2012 (n = 441/583) completed the Sydney Post BMT Study Survey (SPBS). RESULTS: Forty-five percent of survivors less than 2-year post-transplant reported a dry mouth, 36 % reported mouth ulcers and 19 % had diarrhoea. This was consistent across all survivor groups, regardless of time since transplant. Patients with one or more gastrointestinal (GI) symptoms had significantly lower quality of life scores. There was a significant difference in quality of life scores when comparing those with no GI symptoms to those with one or more symptoms (P = <0.0001). Quality of life was significantly higher in those who once again enjoyed mealtimes (P < 0.0001). Males were more likely to be satisfied with their body weight compared to females (P = 0.009). The median body mass index (BMI) for all patients reporting body weight satisfaction was significantly lower (BMI 23.5) than those reporting dissatisfaction (BMI 27.5) (P = <0.0001). Survivors who had a normal BMI had significantly higher rates of body weight satisfaction compared to underweight, overweight and obese survivors (P = <0.0001). Those survivors who were overweight or obese were significantly more likely to be diabetic (P = 0.008). CONCLUSION: This study revealed an important relationship between gastrointestinal symptoms, body weight and body image and survivor's quality of life. It provides further support for the importance of nutrition therapy post-BMT.

Epidemiology of complementary and alternative medicine therapy use in allogeneic hematopoietic stem cell transplant survivorship patients in Australia.

In addition to prescribed conventional medicines, many allogeneic hematopoietic stem cell transplant (HSCT) survivors also use complementary and alternative medical therapies (CAM), however, the frequency and types of CAMs used by allogeneic HSCT survivors remain unclear. Study participants were adults who had undergone an allogeneic HSCT between 1st January 2000 and 31st December 2012. Participants completed a 402-item questionnaire regarding the use of CAM, medical complications, specialist referrals, medications and therapies, infections, vaccinations, cancer screening, lifestyle, and occupational issues and relationship status following stem cell transplantation. A total of 1475 allogeneic HSCT were performed in the study period. Of the 669 recipients known to be alive at study sampling, 583 were contactable and were sent study packs. Of 432 participants who returned the completed survey (66% of total eligible, 76% of those contacted), 239 (54.1%) HSCT survivors used at least one form of CAM. These included dietary modification (13.6%), vitamin therapy (30%), spiritual or mind-body therapy (17.2%), herbal supplements (13.5%), manipulative and body-based therapies (26%), Chinese medicine (3.5%), reiki (3%), and homeopathy (3%). These results definitively demonstrate that a large proportion of HSCT survivors are using one or more form of CAM therapy. Given the potential benefits demonstrated by small studies of specific CAM therapies in this patient group, as well as clearly documented therapies with no benefit or even toxicity, this result shows there is a large unmet need for additional studies to ascertain efficacy and safety of CAM therapies in this growing population.

Adherence to cancer screening guidelines in Australian survivors of allogeneic blood and marrow transplantation (BMT).

Allogeneic Blood and Marrow Transplant (BMT) survivors are at high risk of secondary cancers. Although current guidelines endorse survivors following Country-specific general population screening recommendations to mitigate this risk, little is known about cancer screening adherence in Australian BMT survivors. We conducted a cross-sectional survey of 441 BMT survivors who were >1 year post transplant, to explore rates of screening for secondary cancers and to identify barriers to cancer screening recommendations. Survey instruments included the Sydney Post-BMT Survey, FACT-BMT, DASS 21, The Chronic Graft versus Host Disease (GVHD) Activity Assessment-Patient Self-Report (Form B), the Lee Chronic GVHD Symptom Scale, Fear of Cancer Recurrence Scale, and The Post Traumatic Growth Inventory. Fifty-seven percent of respondents were male, median age 54 years, and 40% were >6 years post-BMT. Rates of cancer screening adherence were as follows: cervical 63.4%, breast 53.3%, skin 52.4%, and bowel 32.3%. Older BMT survivors and those >2 years post transplant were more likely to undergo cancer screening. Improved quality of life was associated with screening for skin, breast, and cervical cancer. Fear of cancer recurrence negatively impacted on cervical screening. For those who had not undergone screening, the majority reported not being advised to do so by their treatment team. This study is the largest and most comprehensive to date exploring cancer screening adherence in BMT survivors in Australia. These data provide the basis for health service reform to better meet the needs of BMT survivors and provide evidence to support counseling and education of both patients and professionals.

A survey of fertility and sexual health following allogeneic haematopoietic stem cell transplantation in New South Wales, Australia.

Four hundred and twenty-one adult allogeneic haematopoietic stem cell transplant (HSCT) survivors participated in a cross-sectional study to assess sexual dysfunction and infertility post-transplant. Survey instruments included the Sydney Post-Blood and Marrow Transplant (BMT) Survey, Functional Assessment of Cancer Treatment (FACT) - BMT, the Depression, Anxiety, Stress Scales (DASS 21), the Chronic Graft-versus-Host Disease (cGVHD) Activity Assessment- Patient Self Report (Form B), the Lee cGVHD Symptom Scale and The Post-Traumatic Growth Inventory. Most HSCT survivors reported sexual difficulties (51% of males; 66% of females). Men reported erectile dysfunction (79%) and decreased libido (61·6%) and women reported loss of libido (83%), painful intercourse (73%) and less enjoyment of sex (68%). Women also commonly reported vaginal dryness (73%), vaginal narrowing (34%) and vaginal irritation (26%). Woman had much higher rates of genital cGvHD than men (22% vs. 5%). Age and cGVHD were significantly associated with sexual dysfunction. Few survivors had children following transplant (3·3%). However, for those of reproductive age at HSCT, 22% reported trying to conceive, with 10·3% reporting success. This study is the largest to date exploring sexual function in survivors of allo-HSCT. This data provides the basis for health service reform to better meet the needs of HSCT survivors, including evidence to support counselling and education both pre- and post-transplant.

What They Want: Inclusion of Blood and Marrow Transplantation Survivor Preference in the Development of Models of Care for Long-Term Health in Sydney, Australia.

Four hundred forty-one adult allogeneic blood and marrow transplantation (BMT) survivors participated in a cross-sectional survey to assess long-term follow-up (LTFU) model of care preference. Survey instruments included the Sydney Post BMT Survey, Functional Assessment of Cancer Therapy-BMT, Depression Anxiety Stress Scales 21, the Chronic GVHD Activity Assessment-Patient Self Report (Form B), the Lee Chronic GVHD Symptom Scale and the Post-Traumatic Growth Inventory. We found most BMT survivors (74%) would prefer LTFU with their transplantation physicians alone or in combination with transplantation center-linked services (satellite clinics or telemedicine) Over one-quarter indicated a preference for receiving comprehensive post-transplantation care in a "satellite" clinic staffed by their BMT team situated closer to their place of residence, with higher income, higher educational level, and sexual morbidity being significant social factors influencing this preference. Regular exercise was reported less often in those who preferred telemedicine, which may reflect reduced mobility. The factor most strongly associated with a preference for transplantation center follow-up was the severity of chronic graft-versus-host disease. Full- and part-time work were negatively associated with transplantation center follow-up, possibly implying decreased dependency on the center and some return to normalcy. This study is the first to explore the preferences of BMT survivors for long-term post-transplantation care. These data provides the basis for LTFU model of care development and health service reform consistent with the preferences of BMT survivors.

Influence of Stem Cell Source on Outcomes of Allogeneic Reduced-Intensity Conditioning Therapy Transplants Using Haploidentical Related Donors.

We compared outcomes for 2 retrospective cohorts of patients undergoing reduced-intensity conditioning (RIC) therapy transplants using haploidentical related donors and post-transplant prophylaxis against graft-versus-host disease (GVHD) with high-dose cyclophosphamide, tacrolimus, and mycophenolate. The first cohort of 13 was transplanted with bone marrow (BM) as the stem cell source, whereas the second cohort of 23 used peripheral blood stem cells (PBSCs) mobilized with granulocyte colony-stimulating factor. The BM cohort received a single 60-mg/kg dose of cyclophosphamide on day +3, whereas the PBSC cohort received 2 doses on days +3 and +4. Patients in the first cohort were slightly older and had a higher proportion of acute myeloid leukemia, but there were no differences in the distribution of Disease Risk Index scores between the 2 groups. Patients in the PBSC group received double the number of CD34(+) cells in the stem cell graft. Times to neutrophil and platelet recovery were not different between the 2 groups. Three patients, all in the PBSC group, failed to engraft but recovered with autologous hemopoiesis and survived. The 6-month cumulative incidences of acute GVHD were 55.1% for BM and 48.5% for PBSCs (P = .651), whereas 24-month cumulative rates for chronic GHVD were 28.6% for BM and 32.3% for PBSCs (P = .685). Only 2 patients, both in the BM group, died of nonrelapse causes, both of second cancers. The 2-year cumulative incidences of relapse were 43.9% for BM and 23.5% for PBSCs (P = .286). Overall survival at 2 years was significantly better for PBSC patients (P = .028), at 83.4% versus 52.7% for BM. Relapse-free and event-free survival did not differ significantly between BM and PBSC groups. In this retrospective analysis, we conclude that the use of PBSCs for haploidentical RIC transplants is a feasible strategy, with equivalent rates of acute and chronic GVHD and risk of relapse and low nonrelapse mortality compared with BM.
