Allogeneic bone marrow transplantation in the management of chronic neutrophilic leukemia.

Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative disorder characterized by a clonal proliferation of mainly mature neutrophils, which is often difficult to differentiate from reactive leukocytosis or other myeloproliferative disorders. Treatment to date has focused on disease control rather than cure. Once the disease has progressed to a more aggressive leukemia there is typically little chance of obtaining a long lasting remission due to the older age of most patients as well as the acquisition of multiple poor prognostic cytogenetic abnormalities. In this case report we describe a successful sibling allogeneic bone marrow transplant in a 60-year-old man with CNL performed while he was still in the stable phase of his disease. We propose that even in older patients this curative approach may be considered in selected patients at an early stage of their disease, similar to the approach taken with chronic myelogenous leukemia.

Illness intrusiveness among survivors of autologous blood and marrow transplantation.

BACKGROUND: Illness-induced disruptions to lifestyles, activities, and interests (i.e., illness intrusiveness) compromise subjective well-being. The authors measured illness intrusiveness in autologous blood and bone marrow transplantation (ABMT) survivors and compared the results with survivors of solid organ transplants. METHODS: Forty-four of 64 consecutive ABMT survivors referred to the University of Toronto ABMT long-term follow-up clinic completed the Illness Intrusiveness Ratings Scale (IIRS), the Affect Balance Scale (ABS), the Atkinson Life Happiness Rating (ATKLH), the Beck Hopelessness Scale (BHS), and the Center for Epidemiologic Studies Depression (CES-D) Scale. Mean time from ABMT to evaluation was 4.6 +/- 2.8 years. All patients were in remission or had stable disease at the time of evaluation. Autologous blood and bone marrow transplantation patients' IIRS scores were compared with scores reported by recipients of kidney (n = 357), liver (n = 150), lung (n = 77), and heart (n = 60) transplants. RESULTS: Mean IIRS score for the 44 ABMT patients was 37.2 +/- 17 (maximum possible score, 91; minimum possible score, 13). Higher IIRS scores correlated with lower scores on the ABS (r = -0.54; P < 0.0001), and ATKLH (r = -0.44; P = 0.004), and with higher scores on the BHS (r = 0.58; P < 0.0001) and CES-D (r = 0.48; P < 0.0001). The authors compared IIRS scores from the ABMT survivors with scores from recipients of solid organ transplants. Scores were corrected for age, gender, and time from transplant to evaluation. Corrected mean IIRS scores for the marrow (37.5), kidney (38.9), heart (40.0), lung (30.1), and liver (32.3) transplant recipients differed significantly (P < 0.0001 by analysis of covariance). Higher scores among marrow, kidney, and heart transplant survivors were caused by increased scores in the instrumental domain of the IIRS that measures disruptions in health, work, financial situation, and active recreation. CONCLUSIONS: Despite achieving a remission after ABMT, patients continue to experience illness intrusiveness compromising subjective well-being.

Acute lymphoblastic leukemia with multiple cytogenetic abnormalities secondary to treatment of Ewing's sarcoma.

We report the case of a 22-year-old man with Ewing's sarcoma who attained a complete remission (CR) after combination radiotherapy and chemotherapy. Secondary acute lymphoblastic leukemia with multiple cytogenetic abnormalities involving chromosome 5 and 7 developed 16 years later. The patient underwent induction chemotherapy and entered a CR. Peripheral blood stem cell transplantation from a matched sibling was performed successfully and he is in complete remission of both ALL and Ewing's sarcoma.

Secondary acute myeloid leukemia 4 years after the diagnosis of hairy cell leukemia: case report and review of the literature.

A 49-year-old man diagnosed with hairy cell leukemia (HCL) achieved a complete remission lasting 4 years after treatment with cladrabine and subsequently developed acute myeloid leukemia. Although a wide variety of second malignancies have been noted in HCL with an incidence of 8.7%, acute myeloid leukemia (AML) has been reported only once previously in a splenectomized patient who had been treated with alpha interferon.

Parentage testing implications of male fertility after allogeneic bone marrow transplantation.

Fertility is expected to be reduced after the extensive chemotherapy and/or radiotherapy that is needed for conditioning prior to bone marrow transplantation. However, a male patient can be fertile, and in very rare situations such as reported here, this may confuse subsequent paternity testing. The patient, initially excluded as the biological father by red cell types but not by HLA, was subsequently included after the history of his previous marrow transplant was revealed, a review of the HLA results and further RFLP testing on buccal mucosal cells. This case points to the need for good history taking before performing paternity testing.

Acute intestinal graft-versus-host disease in a syngeneic bone marrow transplant recipient.

BACKGROUND: We report a case of intestinal graft-versus-host disease (GVHD) in a syngeneic bone marrow transplant patient. METHODS: Several days after receiving a bone marrow transplant from his identical twin for treatment of non-Hodgkin's lymphoma, a 47-year-old man developed a skin rash and diarrhea. RESULTS: A colonic biopsy on day +15 revealed characteristic changes of acute intestinal GVHD. Molecular studies (microsatellite DNA and HLA sequence-specific primer polymerase chain reaction analyses) confirmed the genotypic identity of donor and host and the improbability of transfusion-associated GVHD. CONCLUSION: This case illustrates that pathological evidence of GVHD does not absolutely require the presence of genetic differences between host and donor and questions existing concepts about the nature of cyclosporine-induced GVHD.

Abnormal thyroid stimulating hormone (TSH) levels in adults following allogeneic bone marrow transplants.

Thyroid function abnormalities in 270 adult patients post-BMT are described. Various conditioning regimens were used and the effects of three TBI and one chemotherapy only based regimens are compared. The overall incidence of elevated TSH is 8.9; 3.8, 7.2 and 16.7% in those patients who received 300, 500 and 1200 cGy respectively and 11.7% in those who received BuCy conditioning. Three cases (1.1%) of clinial hypothyroidism were observed. Compensated hypothyroidism defined as an elevated TSH in the presence of normal T3, T4 levels and transient in some cases, was the most common finding. All but four cases occurred in the first 2 years after BMT. In the remaining four, three occurred in patients with chronic GVHD. The results reported here show a lower prevalence than observed in most other reviews, particularly for children. A trend was observed with increasing radiation doses. The results are not significantly different from those we observed in the BuCy regimen.

Quality of life following bone marrow transplantation: a comparison of patient reports with population norms.

All surviving patients who had received an allogeneic bone marrow transplant at the Princess Margaret Hospital were asked to participate in a health-related quality of life (HQL) study using the Medical Outcomes Survey-Short Form 36 (MOS SF-36), the Satisfaction with Life Domains Scale-Bone Marrow Transplantation (SLDS-BMT) and a current symptoms checklist. The main objective was to compare the health status of BMT survivors with age-adjusted population norms. Of the 251 patients contacted, 93% returned questionnaires. The median follow-up after BMT was 40 months, ranging from 1-253 months. On average, survivors had some diminished HQL relative to the health status of the population in general. Time since transplant had a significant influence on HQL; those less than 3 years from transplant experienced considerable impairment while those who had survived beyond this point were indistinguishable from the normal population in most domains and significantly better in certain psychosocial aspects of health. Many patients still reported symptoms months after BMT; some were mildly affected while others experienced more troublesome symptoms. However, 81% of patients were satisfied with the HQL outcome that they had achieved and 94% would recommend a transplant for someone in similar circumstances.

Successful pregnancy after allogeneic bone marrow transplant with embryos isolated before transplant.

METHODS AND RESULTS: Autologous embryos from in vitro-fertilized ova were successfully implanted in a 29-year-old woman, 2 years after successful allogeneic bone marrow transplant (BMT) for chronic myeloid leukemia (CML). A second pregnancy, similarly initiated, is in progress at 4 years posttransplant. CONCLUSION: Our experience offers a fertility-salvaging technique to some women after cytotoxic therapy, where time permits ovarian hyperstimulation before the need for definitive myeloblative therapy of their malignancy, and where the risk of subsequent infertility is high.

Intensive remission induction therapy for chronic myeloid leukemia in blast phase with a goal of post-remission bone marrow transplant--a pilot study.

An intensive protocol utilizing mitoxantrone, high-dose cytarabine, vincristine, etoposide and methylprednisolone as induction therapy for chronic myeloid leukemia in blast transformation is described. Fourteen patients were treated, with a remission/second chronic phase achieved in 64%. None of the 3 patients older than 50 yr responded. Complete hematological responses were seen in 9 of the 11 younger patients, 4 of whom also became BCR-ABL negative by Southern Blot analysis. Four patients went on to allogeneic bone marrow transplant. Median remission durations were 4.5 (1-5) and 8.5 (5-16) months in the non-transplanted and transplanted cohorts, respectively. Median survival is 1.5 (0.5-3), 9.5 (7-14) and 17 (14-61+) months in the non-responding, responding non-transplanted and transplanted cohorts, respectively. Toxicity, particularly gastrointestinal, was significant. This represents an aggressive protocol that should be reserved for patients who are potential transplant candidates.
