A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed right testicular mass in contiguity with the inguinal canal to the ipsilateral retroperitoneum, associated with right hydronephrosis. Due to the risk of germ-cell tumor in undescended testicle, the patient underwent radical right orchiectomy. The pathological examination showed recurrence of acute myeloid leukemia in the testis. He was referred to oncology for adjuvant therapy. Our literature review found no similar cases described

The radiological and pathological skeletal manifestations in a case of adult T-cell leukemia are presented. The authors have emphasized the presence of multiple areas of localized subperiosteal resorption as a helpful finding in the differential diagnosis between adult T-cell leukemia and multiple myeloma and hyperparathyroidism. A possible mechanism for these radiological features and its similarity to those of other T-cell malignancies are discussed briefly. (orig./SHA)

Full Text Available Michael E RyttingDepartment of Pediatrics and Leukemia, University of Texas MD Anderson Cancer Center, Houston, TX, USAAbstract: Asparaginase preparations deplete asparagine in acute lymphoblastic leukemia (ALL blasts. Asparaginase in its various forms is an important component of treatment regimens for pediatric ALL. Recently, interest and use of asparaginase in adult patients with ALL has increased, particularly in young adults. There is much less information on asparaginase use and toxicity in adult compared with pediatric populations. This review surveys prior published studies of the three most commonly used asparagine preparations as used in adult patients, and discusses important toxicities encountered in adult patients who receive asparaginase preparations.Keywords: asparaginase, leukemia, adults, children

Adult T-cell leukemia/lymphoma treatment in Bahia, Brazil

Directory of Open Access Journals (Sweden)

Pedro Dantas Oliveira

Full Text Available Abstract Background: Adult T-cell leukemia/lymphoma is a peripheral disease associated with human T-cell lymphotropic virus type 1. Treatment is carried out according to clinical type with watchful waiting being recommended for less aggressive types. Aggressive adult T-cell leukemia/lymphoma is generally treated with chemotherapy and/or antivirals. The objective of this study was to correlate the survival of patients diagnosed in Bahia, Brazil, with the therapeutic approaches employed and to evaluate what issues existed in their treatment processes. Methods: Eighty-three adult T-cell leukemia/lymphoma patients (26 smoldering, 23 chronic, 16 acute, 13 lymphoma and five primary cutaneous tumoral with available data were included in this study. Results: Complete response was achieved in seven smoldering patients with symptomatic treatment, in two with chronic disease using antivirals/chemotherapy, in one with acute disease using antivirals and in one lymphoma using the LSG15 regimen [vincristine, cyclophosphamide, doxorubicin, and prednisolone (VCAP; doxorubicin, ranimustine, and prednisolone (AMP; and vindesine, etoposide, carboplatin, and prednisolone (VECP]. Smoldering patients who received symptomatic treatment presented longer survival. Favorable chronic patients treated with antivirals presented longer survival compared to the unfavorable subtype. However, for the acute form, first-line chemotherapy was better, albeit without significance, than antivirals. Only one of the patients with lymphoma and primary cutaneous tumors responded. Conclusions: Watchful waiting associated with phototherapy represents the best option for smoldering adult T-cell leukemia/lymphoma with survival in Bahia being superior to that described in Japan. There was a trend of better results with zidovudine/interferon-alpha in favorable chronic disease. Excellent results were achieved in the lymphoma type treated with the LSG15 protocol. Patients are diagnosed late

Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

Recurrent Childhood Animal Cruelty and Its Link to Recurrent Adult Interpersonal Violence.

Trentham, Caleb E; Hensley, Christopher; Policastro, Christina

2018-06-01

In the early 1960s, researchers began to examine the potential link between childhood animal cruelty and future interpersonal violence. Findings since then have been inconsistent in establishing a relationship between the two. This may be due to researchers failing to measure the recurrency of childhood animal abuse and the recurrency of later violent acts committed in adulthood. The current study, using data from 257 inmates at a medium-security prison in a Southern state, is a replication of research conducted by Tallichet and Hensley, and Hensley, Tallichet, and Dutkiewicz, which examined this recurrency issue. The only statistically significant predictor of recurrent adult interpersonal violence in this study was recurrent childhood animal cruelty. Inmates who engaged in recurrent childhood animal cruelty were more likely to commit recurrent adult interpersonal violence. Respondents' race, education, and childhood residence were not significant predictors of the outcome variable.

The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome. A total of 110 adult patients (34 ± 12 years) with ALL underwent TBI (6 fractions of 2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported. Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72 %, respectively. In all, 29 % (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22 %, and 60 and 52.7 %, respectively. The most frequent late reaction wascGVHD of the skin (n = 33, 30 %). In addition, 15.5 % (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110 = 28 %); 12 of 110 patients (11 %) presented with symptoms from osteoporosis, 5 of 110 patients (4.5 %) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11 % reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented. Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic

Two patients with T-cell malignancy having radiographic manifestations of generalized and localized bone demineralization are reported. One, a 53-year-old-man, had marked osteoporosis and severe hypercalcemia, but no clinical evidence of leukemia throughout his illness. At autopsy there was no definite evidence of bone involvement. Histologic proof was obtained from abdominal skin which revealed ''adult T-cell leukemia/lymphoma (ATLL).'' The second case, a 33-year-old man, complained of arthralgia in his hands and feet; radiographs showed severe localized demineralization and pathologic fractures. Specimens of his peripheral blood, cervical lymph nodes, and bone marrow revealed ATLL cells. (orig.)

Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adult T-cell acute lymphoblastic leukemia uniformly treated during the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. HOXA-positive patients had markedly higher rates of an early thymic precursor-like immunophenotype (40.8% versus 14.5%, P=0.0004), chemoresistance (59.3% versus 40.8%, P=0.026) and positivity for minimal residual disease (48.5% versus 23.5%, P=0.01) than the HOXA-negative group. These differences were due to particularly high frequencies of chemoresistant early thymic precursor-like acute lymphoblastic leukemia in HOXA-positive cases harboring fusion oncoproteins that transactivate HOXA Strikingly, the presence of an early thymic precursor-like immunophenotype was associated with marked outcome differences within the HOXA-positive group (5-year overall survival 31.2% in HOXA-positive early thymic precursor versus 66.7% in HOXA-positive non-early thymic precursor, P=0.03), but not in HOXA-negative cases (5-year overall survival 74.2% in HOXA-negative early thymic precursor versus 57.2% in HOXA-negative non-early thymic precursor, P=0.44). Multivariate analysis further revealed that HOXA positivity independently affected event-free survival (P=0.053) and relapse risk (P=0.039) of chemoresistant T-cell acute lymphoblastic leukemia. These results show that the underlying mechanism of HOXA deregulation dictates the clinico-biological phenotype, and that the negative prognosis of early thymic precursor acute lymphoblastic leukemia is exclusive to HOXA-positive patients, suggesting that early treatment intensification is currently

B-cell acute lymphoblastic leukemia (B-ALL) is a common childhood malignancy that also affects young adults. Although current treatments have significant toxicities, children with chemotherapy susceptible subtypes have high survival rates. However, less than 10 percent of children and young adults with newly-diagnosed or recurrent B-ALL that is insensitive to therapy survive, and this rate has not budged in the last 20 years.

Today, long-term survival is achieved in more than 80% of children 1 to 10 years old with acute lymphoblastic leukemia (ALL). However, cure rates for adults and adolescents and young adults (AYA) with ALL remain relatively low, at only 40% to 50%. Age is a continuous prognostic variable in ALL, with no single age at which prognosis deteriorates markedly. Within childhood ALL populations, older children have shown inferior outcomes, whereas younger adults have shown superior outcomes among adult ALL patients. The type of treatment (pediatric-based versus adult-based) for AYA has recently been a matter of debate. In this article the biology and treatment of ALL in AYA is reviewed.

A 56-year-old female was admitted because of generalized lymphadenopathy. Based upon histological findings of biopsied lymph node, malignant lymphoma, diffuse large cell type was diagnosed. The surface marker analysis showed that malignant cells were positive for CD4 and CD2 but negative for CD8. Although anti-ATLA (adult T-cell leukemia associated antigen) antibody was negative with the use of a gelatin particle agglutination method (P.A.), other methods such as an indirect immunofluorescence assay (I.F.), an enzyme-linked immunosorbent assay (E.I.A.) and a Western blotting assay revealed the positivity for anti-ATLA antibody. Adult T-cell leukemia/lymphoma (ATL/L) was confirmed by the presence of monoclonal integration of HTLV-I proviral DNA in biopsied specimen. This case, showing a pattern of P.A. (-) and I.F. (+), is extremely unusual, because I.F. and P.A. show highly close correlation. Thus, it is important to employ different methods for screening of anti-ATLA antibodies in the diagnosis of ATL/L.

Full Text Available Human T-cell leukemia virus-associated adult T-cell leukemia-lymphoma (ATLL has a very poor prognosis, despite trials of a variety of different treatment regimens. Virus expression has been reported to be limited or absent when ATLL is diagnosed, and this has suggested that secondary genetic or epigenetic changes are important in disease pathogenesis.We prospectively investigated combination chemotherapy followed by antiretroviral therapy for this disorder. Nineteen patients were prospectively enrolled between 2002 and 2006 at five medical centers in a phase II clinical trial of infusional chemotherapy with etoposide, doxorubicin, and vincristine, daily prednisone, and bolus cyclophosphamide (EPOCH given for two to six cycles until maximal clinical response, and followed by antiviral therapy with daily zidovudine, lamivudine, and alpha interferon-2a for up to one year. Seven patients were on study for less than one month due to progressive disease or chemotherapy toxicity. Eleven patients achieved an objective response with median duration of response of thirteen months, and two complete remissions. During chemotherapy induction, viral RNA expression increased (median 190-fold, and virus replication occurred, coincident with development of disease progression.EPOCH chemotherapy followed by antiretroviral therapy is an active therapeutic regimen for adult T-cell leukemia-lymphoma, but viral reactivation during induction chemotherapy may contribute to treatment failure. Alternative therapies are sorely needed in this disease that simultaneously prevent virus expression, and are cytocidal for malignant cells.

Studies on adolescents and young adults with acute lymphoblastic leukemia suggest better results when using pediatric protocols for adult patients, while corresponding data for acute myeloid leukemia (AML) are limited. We investigated disease characteristics and outcome for de novo AML patients 10-30 years old treated in pediatric or adult departments. We included 166 patients 10-18 years of age with AML treated according to the pediatric NOPHO-protocols (1993-2009) compared with 253 patients aged 15-30 years treated in hematology departments (1996-2009) in the Nordic countries. The incidence of AML was 4.9/million/year for the age group 10-14 years, 6.5 for 15-18 years, and 6.9 for 19-30 years. Acute promyelocytic leukemia (APL) was more frequent in adults and in females of all ages. Pediatric patients with APL had similar overall survival as pediatric patients without APL. Overall survival at 5 years was 60% (52-68%) for pediatric patients compared to 65% (58-70%) for adult patients. Cytogenetics and presenting white blood cell count were the only independent prognostic factors for overall survival. Age was not an independent prognostic factor. No difference was found in outcome for AML patients age 10-30 years treated according to pediatric as compared to adult protocols. © 2015 Wiley Periodicals, Inc.

Two cases of cytomegalic inclusion disease complicating chronic granulocytic leukemia and subacute lymphocytic leukemia in adult Japanese males in Nagasaki, Japan are reported. Both cases had concomitant pulmonary infection by pneumocystis carinii and both were exposed to the atomic bomb in 1945. It is believed these are the first reported autopsy cases of adult cytomegalic inclusion disease in which typical cytomegalic inclusion bodies were seen in the parenchymal cells of the salivary glands. Previously reported cases of adult cytomegalic inclusion disease complicating leukemia and malignant lymphoma are briefly summarized. Present knowledge of the relationship between cytomegalic and pneumocystis infections and association with lymphoma and leukemia is reviewed. The possible roles of chemotherapeutic agents and of radiation in the development of the cytomegalic and pneumocystis infections are also briefly discussed. 43 references, 4 figures, 2 tables.

Vaccination of adult and newborn mice of a resistant strain (C57BL/6J) against challenge with leukemias induced by Moloney murine leukemia virus

Reif, A.E.

1985-01-01

Adult or newborn C57BL/6J mice were immunized with isogenic Moloney strain MuLV-induced leukemia cells irradiated with 10,000 rads or treated with low concentrations of formalin. Groups of immunized and control mice were challenged with a range of doses of viable leukemia cells, and tumor deaths were recorded for 90 days after challenge. Then, the doses of challenge cells which produced 50% tumor deaths were calculated for immunized and control mice. The logarithm of their ratio quantified the degree of protection provided by immunization. For adult C57BL/6J mice, a single immunization with MuLV-induced leukemia cells was not effective; either cells plus Bacillus Calmette-Guerin or Corynebacterium parvum, or else two immunizations with irradiated leukemia cells were needed to produce statistically significant increases in the values of the doses of challenge cells which produced 50% tumor deaths. Cross-protection was obtained by immunization with other isogenic MuLV-induced leukemias, but not by immunization with isogenic carcinogen-induced tumors or with an isogenic spontaneous leukemia. For newborn mice, a single injection of irradiated leukemia cells provided 1.3 to 1.5 logs of protection, and admixture of B. Calmette-Guerin or C. parvum increased this protection to 2.4 to 2.7 logs. Since irradiated and frozen-thawed MuLV-induced leukemia cells contained viable MuLV, leukemia cells treated with 0.5 or 1.0% formalin were tested as an alternative. A single injection of formalin-treated isogenic leukemia cells admixed with C. parvum provided between 1.7 and 2.8 logs of protection. These results demonstrate that a single vaccination of newborn animals against a highly antigenic virally induced leukemia produces strong protection against a subsequent challenge with viable leukemia cells

Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

Recurrent deletions of the long arm of chromosome 5 were detected in 23/200 cases of T-cell acute lymphoblastic leukemia. Genomic studies identified two types of deletions: interstitial and terminal. Interstitial 5q deletions, found in five cases, were present in both adults and children with a female predominance (chi-square, P=0.012). Interestingly, these cases resembled immature/early T-cell precursor acute lymphoblastic leukemia showing significant down-regulation of five out of the ten top differentially expressed genes in this leukemia group, including TCF7 which maps within the 5q31 common deleted region. Mutations of genes known to be associated with immature/early T-cell precursor acute lymphoblastic leukemia, i.e. WT1, ETV6, JAK1, JAK3, and RUNX1, were present, while CDKN2A/B deletions/mutations were never detected. All patients had relapsed/resistant disease and blasts showed an early differentiation arrest with expression of myeloid markers. Terminal 5q deletions, found in 18 of patients, were more prevalent in adults (chi-square, P=0.010) and defined a subgroup of HOXA-positive T-cell acute lymphoblastic leukemia characterized by 130 up- and 197 down-regulated genes. Down-regulated genes included TRIM41, ZFP62, MAPK9, MGAT1, and CNOT6, all mapping within the 1.4 Mb common deleted region at 5q35.3. Of interest, besides CNOT6 down-regulation, these cases also showed low BTG1 expression and a high incidence of CNOT3 mutations, suggesting that the CCR4-NOT complex plays a crucial role in the pathogenesis of HOXA-positive T-cell acute lymphoblastic leukemia with terminal 5q deletions. In conclusion, interstitial and terminal 5q deletions are recurrent genomic losses identifying distinct subtypes of T-cell acute lymphoblastic leukemia. Copyright© Ferrata Storti Foundation.

There is a paucity of studies investigating adult leukemia and air pollution. To address this gap, we analyzed data from a Canadian population-based case–control study conducted in 1994–1997. Cases were 1064 adults with incident leukemia and controls were 5039 healthy adults. We used data from satellites and fixed-site monitoring stations to estimate residential concentrations of NO 2 and fine particulate matter (PM 2.5 ) for the period prior to diagnosis, starting in 1975 and ending in 1994. We modeled the average annual exposure of each subject. Odds ratios (OR) and their 95% confidence intervals (CI) were estimated using logistic regression, adjusted for age, gender, province, smoking, education, body mass index, income, and self-reported exposures to ionizing radiation and benzene. We found an ‘n-shaped’ response function between exposure to NO 2 and all forms of leukemia: from the tenth percentile to the median (4.51 to 14.66 ppb), the OR was 1.20; 95% CI: 0.97–1.48 and from the 75th percentile to the 90th (22.75 to 29.7 ppb), the OR was 0.79; 95% CI 0.68–0.93. For PM 2.5 we found a response function consistent with a linear model, with an OR per 10 μg/m 3 of 0.97 (95% CI 0.75–1.26). For chronic lymphocytic leukemia we found response functions that were consistent with a simple linear model, with an OR per 5 ppb of NO 2 of 0.93 (95% CI 0.86–1.00) and an OR per 10 μg/m 3 of PM 2.5 of 0.62 (95% CI 0.42–0.93). In summary, for chronic lymphocytic leukemia we found no evidence of an association with air pollution and with all forms of leukemia we found weak evidence of an association only at low concentrations of NO 2 . It is possible that these inconsistent results may have arisen because of unaccounted urban/rural differences or possibly from a selection effect, especially among controls. - Highlights: • Analyzed associations between incidence of adult leukemia and PM • We used 20-year residential histories to estimate average annual

Prolonged Survival of Acute Lymphoblastic Leukemia with Intrathecal Treatments for Isolated Central Nervous System Relapse

Directory of Open Access Journals (Sweden)

Elan Gorshein

2018-01-01

Full Text Available Acute lymphoblastic leukemia is commonly cured when diagnosed in the pediatric population. It portends a poorer prognosis if present in adult patients. Although adults frequently achieve complete remission, relapse rates are substantial, particularly among the elderly and high-risk populations. In the absence of prophylactic intrathecal chemotherapy, more than half of patients may develop CNS involvement or relapse, which is associated with significant risk for systemic illness. This report describes a patient with acute lymphoblastic leukemia with repeated isolated CNS relapses. This case should remind clinicians that isolated CNS disease in the absence of systemic recurrence could successfully respond to intrathecal therapy and offer patients a favorable quality of life.

Radiogenic leukemia revisited

International Nuclear Information System (INIS)

Moloney, W.C.

1987-01-01

Radiation-induced leukemia is considered to be similar to the de novo disease. However, following an analysis of clinical and hematological findings in leukemia occurring in irradiated cervical cancer patients, adult Japanese atomic-bomb survivors, and spondylitics treated with x-ray, striking differences were noted. Acute leukemias in cervical cancer patients and Japanese survivors were similar in type to acute de novo leukemias in adults. Cell types among spondylitics were very dissimilar; rare forms, eg, acute erythromyelocytic leukemia (AEL) and acute megakaryocytic leukemia, were increased. Pancytopenia occurred in 25 of 35 cases and erythromyelodysplastic disorders were noted in seven of 35 acute cases. The leukemias and myelodysplastic disorders closely resembled those occurring in patients treated with alkylating agents. This similarity suggests a common pathogenesis involving marrow stem cell injury and extra-medullary mediators of hematopoiesis. Investigation of early acute leukemias and myelodysplastic disorders with newer techniques may provide valuable insights into the pathogenesis of leukemia in humans

Acute leukemia is a fatal disease in adults that not only affects the patients who suffer from it but also their family caregivers. No studies have investigated post-traumatic stress disorder symptoms (PTSS) in family caregivers of adult patients with acute leukemia using a matched sample. The current study examined PTSS in adult patients with acute leukemia and their family caregivers and investigated the factors associated with caregivers' PTSS. A total of 163 patient-caregiver dyads completed questionnaires assessing their PTSS, psychological resilience, and perceived social support. Hierarchical linear regression was used to explore the related factors of caregivers' PTSS. More caregivers than patients met caseness criteria for PTSS (36.8% vs. 18.4%, p caregivers, being more closely related to the patients (e.g., spouses and parents), having patients with higher PTSS and having lower psychological resilience were independently associated with more severe PTSS. Caregivers of acute leukemia patients had significantly more severe PTSS than did their patients. This study is the first to investigate PTSS among family caregivers of adult patients with acute leukemia and its related factors in a matched sample. More attention should be paid to the caregivers of patients with acute leukemia to minimize their PTSS and thus improve mental health of caregivers and reduce potential negative consequences for the patients themselves.

Acute lymphoblastic leukemia: a comprehensive review and 2017 update

Science.gov (United States)

Terwilliger, T; Abdul-Hay, M

2017-01-01

Acute lymphoblastic leukemia (ALL) is the second most common acute leukemia in adults, with an incidence of over 6500 cases per year in the United States alone. The hallmark of ALL is chromosomal abnormalities and genetic alterations involved in differentiation and proliferation of lymphoid precursor cells. In adults, 75% of cases develop from precursors of the B-cell lineage, with the remainder of cases consisting of malignant T-cell precursors. Traditionally, risk stratification has been based on clinical factors such age, white blood cell count and response to chemotherapy; however, the identification of recurrent genetic alterations has helped refine individual prognosis and guide management. Despite advances in management, the backbone of therapy remains multi-agent chemotherapy with vincristine, corticosteroids and an anthracycline with allogeneic stem cell transplantation for eligible candidates. Elderly patients are often unable to tolerate such regimens and carry a particularly poor prognosis. Here, we review the major recent advances in the treatment of ALL. PMID:28665419

To explore perceived exercise benefits and barriers in adults with acute leukemia who recently completed an inpatient exercise intervention during induction therapy.
. Descriptive, exploratory design using semistructured interviews.
. Inpatient hematology/oncology unit at North Carolina Cancer Hospital in Chapel Hill.
. 6 adults with acute leukemia aged 35-67 years.
. Content analyses of semistructured interviews that were conducted with each participant prior to hospital discharge.
. Most participants were not meeting the recommended physical activity levels of 150 minutes of moderate-intensity exercise per week before their diagnosis. Patients were highly pleased with the exercise intervention and the overall program. Common barriers to exercise were anxiety and aches and pains.
. Overall, participants experienced physical and psychological benefits with the exercise intervention with no adverse events from exercising regularly during induction chemotherapy. Referrals for cancer rehabilitation management will lead to prolonged recovery benefits.
. Findings inform the nurses' role in encouraging and supporting adults with acute leukemia to exercise and be physically active during their hospitalization. Nurses should also be responsible for assisting patients with physical function activities to increase mobility and enhance overall health-related quality of life.

A glycoprotein of an apparent molecular mass of 46,000, gp 46, was enriched by affinity chromatography from the virus- and cell-free culture medium of adult T-cell leukemia virus (ATLV) infected cells. gp 46 was specifically precipitated with sera from patients with adult T-cell leukemia associated antigen (ATLA). Thus, gp 46 is a novel component of the ATLA antigen complex.

Relationship between triterpenoid anticancer drug resistance, autophagy, and caspase-1 in adult T-cell leukemia

Full Text Available We previously reported that the inflammasome inhibitor cucurbitacin D (CuD induces apoptosis in human leukemia cell lines. Here, we investigated the effects of CuD and a B-cell lymphoma extra-large (Bcl-xL inhibitor on autophagy in peripheral blood lymphocytes (PBL isolated from adult T-cell leukemia (ATL patients. CuD induced PBL cell death in patients but not in healthy donors. This effect was not significantly inhibited by treatment with rapamycin or 3-methyladenine (3-MA. The Bcl-xL inhibitor Z36 induced death in primary cells from ATL patients including that induced by CuD treatment, effects that were partly inhibited by 3-MA. Similarly, cell death induced by the steroid prednisolone was enhanced in the presence of Z36. A western blot analysis revealed that Z36 also promoted CuD-induced poly(ADP ribose polymerase cleavage. Interestingly, the effects of CuD and Z36 were attenuated in primary ATL patient cells obtained upon recurrence after umbilical cord blood transplantation, as compared to those obtained before chemotherapy. Furthermore, cells from this patient expressed a high level of caspase-1, and treatment with caspase-1 inhibitor-enhanced CuD-induced cell death. Taken together, these results suggest that rescue from resistance to steroid drugs can enhance chemotherapy, and that caspase-1 is a good marker for drug resistance in ATL patients.

Examining Fall Recurrence Risk of Homebound Hispanic Older Adults Receiving Home Care Services.

Solis, Guillermina R; Champion, Jane Dimmitt

2017-03-01

Unintentional falls and injuries is a major problem among older adults and the fourth cause of death in the United States. A previous fall event doubles the risk of recurrence and lessens the person's quality of life. Hispanic older adults have higher rates of disability and lower independent functioning due to poor medical health and risk for fall recurrence. Most fall studies focus on fall risk with few studies on fall recurrence in older adults receiving home health care services unrelated to fall incident. A descriptive pilot study of 30 homebound Hispanic older adults receiving home care services who reported a fall within 3 months was conducted by a multidisciplinary team to evaluate risk of fall recurrence. A heightened risk for fall recurrence was identified with high number of chronic illnesses, high intake of medications, vision problems, and prevalence of urinary incontinence. Findings highlight significant number of intrinsic factors for fall risk recurrence and injuries in a Hispanic older adults population that is homebound and receiving home care services. A multidisciplinary evaluation and culturally appropriate interventions to lessen the risk of fall recurrence are recommended.

The aim of this study was to assess the metabolic characteristics and risks of stone recurrence in young adult stone patients in Korea. The medical records of 1532 patients presenting with renal or ureteric stones at our stone clinic between 1994 and 2015 were retrospectively reviewed. Patients were grouped according to age (young adult, 18-29 years; intermediate onset, 30-59 years; old age, ≥60 years) at first presentation, and measurements of clinicometabolic characteristics and risks of stone recurrence were compared. Overall, excretion of urinary stone-forming substances was highest in the intermediate onset group, followed by the young adult and old age groups. Importantly, excretion of urinary citrate was lowest in the young adult group. Kaplan-Meier analyses identified a significant difference between the three age groups in terms of stone recurrence (log rank test, p adult stone patients. Younger age (18-29 years) at first stone presentation was a significant risk factor for stone recurrence, and urinary citrate excretion was an independent risk factor affecting recurrence in this group. Metabolic evaluation and potassium citrate therapy should be considered for young adult stone patients to prevent recurrence.

Acute lymphoblastic leukemia in adolescents and young adults.

The cure rate of acute lymphoblastic leukemia (ALL) in children is 80%, compared to less than half in adults. A major proportion of this cure rate drop occurs in adolescents and young adults (AYAs). The age range defining this population varies between studies, biological characteristics are different from both younger children and older adults, and AYAs are treated either by pediatric or adult oncologists, who often apply different treatment approaches to the same ALL patient population. The outcome of AYAs aged 15-21 years treated by more contemporary pediatric protocols is similar to that of younger children but is inferior when using adult regimens. This motivated studying AYA patients, including those above the age of 21 years, with pediatric or 'pediatrics-inspired' regimens that intensified nonmyelosuppressive drugs such as vincristine, steroids and asparaginase, with very promising preliminary results. Discovering new mutations in AYA ALL will help stratify patients into risk subgroups and identify targets for novel agents. This, together with fine-tuning pediatric chemotherapy principles will hopefully finally decrease the cure rate gap between children and AYAs - and even older adults. © 2014 S. Karger AG, Basel.

Full Text Available Chronic lymphocytic leukemia (CLL is the most common leukemia of adults in the western world and constitutes about 33% of all leukemia′s. The incidence of CLL increases with age and are more common in older population. Chronic myeloid leukemia (CML on the contrary occurs in both young adults and elderly and is a chronic myeloproliferative disease that originates from abnormal pluripotent stem cells and results in involvement of multiple hematopoietic lineages, but predominantly myeloid and less commonly lymphoid. Association between CLL and myeloid malignancies (CML, acute myeloid leukemia and MDS, myelodysplastic syndrome is rare. In literature documenting CLL and CML in same patients, occur either simultaneously or CML is preceded by CLL.

Incidence of adult T-cell leukemia/lymphoma in nonendemic areas.

2015-02-01

Adult T-cell leukemia/lymphoma (ATLL) is a mature T-cell neoplasm with extremely poor prognosis caused by human T-cell leukemia virus type 1 (HTLV-1). The distribution of HTLV-1 and the incidence of ATLL in endemic areas have been well described, however, little is known about the incidences and the trends of the disease in nonendemic areas. Recently, studies have shown that the HTLV-1 carriers are increasing in nonendemic areas. Also, the incidence of ATLL seems to be significantly increasing in nonendemic areas suggesting that HTLV-1 carriers have emigrated from endemic areas. These epidemiologic studies indicate the necessity of edification of the disease caused by HTLV-1 and establishing appropriate preventive methods against infection in nonendemic areas.

Chromosomal rearrangements of the human MLL/KMT2A gene are associated with infant, pediatric, adult and therapy-induced acute leukemias. Here we present the data obtained from 2345 acute leukemia patients. Genomic breakpoints within the MLL gene and the involved translocation partner genes (TPGs) were determined and 11 novel TPGs were identified. Thus, a total of 135 different MLL rearrangements have been identified so far, of which 94 TPGs are now characterized at the molecular level. In all, 35 out of these 94 TPGs occur recurrently, but only 9 specific gene fusions account for more than 90% of all illegitimate recombinations of the MLL gene. We observed an age-dependent breakpoint shift with breakpoints localizing within MLL intron 11 associated with acute lymphoblastic leukemia and younger patients, while breakpoints in MLL intron 9 predominate in AML or older patients. The molecular characterization of MLL breakpoints suggests different etiologies in the different age groups and allows the correlation of functional domains of the MLL gene with clinical outcome. This study provides a comprehensive analysis of the MLL recombinome in acute leukemia and demonstrates that the establishment of patient-specific chromosomal fusion sites allows the design of specific PCR primers for minimal residual disease analyses for all patients.

Chromosomes were studied in cultured T lymphocytes carrying adult T-cell leukemia-associated antigens (ATLA) that were obtained from five Japanese anti-ATLA seropositive healthy adults. Chromosomally abnormal cells were observed in three of the five healthy adults, and these cells were clonal in two subjects. All cells examined in one subject had rearrangements of chromosome nos. 7 and 14. Clonal cells from the second had a minute chromosome of unknown origin. A few cells in the third had nonclonal rearrangements of chromosomes. Thus, ATLA-positive T lymphocytes in some anti-ATLA seropositive healthy people have chromosome aberrations.

A greater understanding of the biology of tumor recurrence should improve adjuvant treatment decision making. We conducted a validation study of the 12-gene recurrence score (RS), a quantitative assay integrating stromal response and cell cycle gene expression, in tumor specimens from patients enrolled onto Cancer and Leukemia Group B (CALGB) 9581. CALGB 9581 randomly assigned 1,713 patients with stage II colon cancer to treatment with edrecolomab or observation and found no survival difference. The analysis reported here included all patients with available tissue and recurrence (n = 162) and a random (approximately 1:3) selection of nonrecurring patients. RS was assessed in 690 formalin-fixed paraffin-embedded tumor samples with quantitative reverse transcriptase polymerase chain reaction by using prespecified genes and a previously validated algorithm. Association of RS and recurrence was analyzed by weighted Cox proportional hazards regression. Continuous RS was significantly associated with risk of recurrence (P = .013) as was mismatch repair (MMR) gene deficiency (P = .044). In multivariate analyses, RS was the strongest predictor of recurrence (P = .004), independent of T stage, MMR, number of nodes examined, grade, and lymphovascular invasion. In T3 MMR-intact (MMR-I) patients, prespecified low and high RS groups had average 5-year recurrence risks of 13% (95% CI, 10% to 16%) and 21% (95% CI, 16% to 26%), respectively. The 12-gene RS predicts recurrence in stage II colon cancer in CALGB 9581. This is consistent with the importance of stromal response and cell cycle gene expression in colon tumor recurrence. RS appears to be most discerning for patients with T3 MMR-I tumors, although markers such as grade and lymphovascular invasion did not add value in this subset of patients.

Smoking is an unconfirmed risk factor for the development of leukemia. The authors examined the potential link using data from the Three Mile Island cohort for the period 1979-1995. Eligible for analysis were 24,539 individuals aged 14 years or older who were followed up over 16 years from the Three Mile Island cohort. The authors identified all incident leukemia cases through the Pennsylvania Department of Health Cancer Registry. They used the Cox proportional hazards model to evaluate the relationships and observed 42 incident leukemia cases, including 15 acute myeloid leukemia (AML) cases, in the cohort. After controlling for other confounding factors, the authors found current smoking to be associated with an increased risk of adult AML (relative risk = 3.47; 95% confidence interval = 1.002-11.99). The authors also observed a marginally significant linear trend of risk of AML associated with the number of years smoked (p = .06). The results from this study suggested that cigarette smoking was associated with an increased risk of adult AML. Further investigation is required to confirm these findings.

2008-01-01

Adult T-cell leukemia/lymphoma (ATLL) is a distinct disease caused by the first discovered human oncogenic retrovirus, human T-cell leukemia virus type-1 (HTLV-1). The peculiarity of this disease is not only in its causative agent HTLV-1 but also in the character of leukemia cells. ATLL cells express the mature helper/inducer T-cell antigens, CD2, CD3, CD4 and CD5 but usually lacking CD8. Despite CD4 expression, it has long been known that ATLL cells exhibit strong immunosuppressive activity ...

Five cases of adult T-cell leukemia-lymphoma (ATL) having typical clinicohematologic and morphologic features but negative for anti-ATLA [antibody to ATL virus (ATLV)-associated antigen (ATLA)] are presented. Some differences in immunologic, epidemiologic, and serologic data between anti-ATLA-positive and -negative ATLs are also described. Expression of ATLA in early primary cultured leukemic cells was found to be negative in three patients tested (Cases 1, 2 and 4), however, a long-term cultured cell line, ATL-6A, derived from peripheral blood leukemia cells from Case 1, was found to express ATLA. Mother of Case 1 and a daughter of Case 2 were anti-ATLA negative. These results indicate that ATLV was involved in certain anti-ATLA-negative ATL patients, at least in Case 1, and that the patient had no detectable immune response against ATLV and ATLA. However, in other cases in which no ATLA reactivity of serum and no ATLA expression in cultured leukemic cells were observed, another possibility such as activation of an unknown cellular oncogene specific for ATL without ATLV involvement may be considered. In order to prove these possibilities definitely, it is necessary to elucidate whether or not proviral DNA of ATLV is integrated into chromosomal DNA of ATL cells and to find a cellular oncogene specific for ATL in the future.

Elias, L; Shaw, M T; Raab, S O

1979-08-01

In an attempt to improve remissions and survivals in previously treated patients with adult acute leukemia, we gave Adriamycin, vincristine, and prednisone for induction therapy, followed by 6-mercaptopurine and methotrexate for maintenance therapy to patients attaining complete remission (CR). The study group consisted of 18 patients with acute myeloblastic leukemia (AML), ten with acute lymphoblastic leukemia, and one with acute undifferentiated leukemia. Only one patient had previously received Adriamycin. Overall, there were ten CRs and two partial remissions. The five CRs and one partial remission in patients with AML occurred among those with one prior induction attempt; none of the eight AML patients with more than one prior induction attempt responded. The actuarial median duration of CR was 15 weeks and was similar for AML and acute lymphoblastic leukemia patients. Responders had a longer median survival (30 weeks) than nonresponders (9 weeks). Thus, although a reasonable number of responses in previously treated patients were obtained with this program, improvements in maintenance therapy are clearly needed.

In the study, we have used the Wilms’ tumor gene (WT1 as a biomarker to evaluate its expression in local adult patients with newly diagnosed acute leukemia, including both acute myeloid and lymphoid leukemias (AML and ALL.Aim: To investigate WT1 gene expression in adult patients with acute leukemia at diagnosis.Methods: Eighteen patients with acute leukemia diagnosed at Singapore General Hospital, Singapore, between September, 2004 and July, 2005 were included in this study. There were fifteen AML and three ALL cases aged from 18 to 71 years old. Total RNA and DNA was extracted from peripheral blood mononuclear cells (PBMCs. Expression of WT1 was detected by nested reverse-transcription polymerase chain reaction (Nested RT-PCR. K562, and 3T3 cells were used as positive- and negative-controls. The results were revalidated using real-time PCR. HLA-A genotyping was performed using sequence specific oligonucleotide polymorphism (SSOP analysis.Results: WT1 gene was exclusively expressed in all eighteen, including three ALL and fi fteen AML, patients. In contrast with WT1 gene, the HLA-A genotyping was remarkably heterogeneous in these patients.Conclusions: WT1 gene expression was observed in local patients with acute leukemia at diagnosis. It may be used as a potential molecular marker for diagnosis, clinical progression of the diseases or monitoring the response to treatment, as well as a target for the development of novel therapeutic approaches.

The Clinical Implications of Methylated p15 and p73 Genes in Adult Acute Lymphoblastic Leukemia

International Nuclear Information System (INIS)

2010-01-01

Aberrant methylation of promoter associated CpG islands is an epigenetic modification of DNA which is associated with gene silencing. It plays an important role in the leukemia pathogenesis. This phenomenon is frequently observed in acute lymphoblastic leukemia (ALL) and results in the functional inactivation of its associated genes. The aim of this study is to investigate the frequency and the prognostic impact of p15 and p73 genes methylation in adult acute lymphoblastic leukemia patients. Patients and Methods: Methylation-specific polymerase chain reaction (PCR) was used to analyze methylation of the p15 and p73 genes in 51 newly diagnosed adult ALL patients. Results: The methylation frequencies of p15 and p73 genes at diagnosis were 41.2% and 27.5% respectively, while concomitant methylation was detected in 14% of the patients. Concomitant methylation of p15 and p73 genes was associated with significant lower rate of CR compared to patients without methylation (57% versus 90%), p=0.008. Overall survival (OS) was not affected by p15 methylation, but was poorer with p73 methylation and the difference was near significant (p=0.059). For patients without meyhylation, the survival benefit was significant when compared to patients with p15, p73 or both genes methylation (p=0.047). The leukemia free survival was not affected by the methylation status of single gene p15 or p73, but tended to be worse in patients with methylated p15, p73 or both genes when compared to patients without methylation (p= 0.08). Conclusion: Aberrant p73 promoter methylation is a potential prognostic factor in adult ALL patients. P15 methylation is frequent in Egyptian adult ALL patients, its concomitant methylation with p73 is of poor prognostic significance. Identification of these molecular targets improve risk assessment and selection of appropriate therapy.

Obesity and Metabolic Syndrome Among Adult Survivors of Childhood Leukemia.

Science.gov (United States)

Gibson, Todd M; Ehrhardt, Matthew J; Ness, Kirsten K

2016-04-01

Treatment-related obesity and the metabolic syndrome in adult survivors of childhood acute lymphoblastic leukemia (ALL) are risk factors for cardiovascular disease. Both conditions often begin during therapy. Preventive measures, including dietary counseling and tailored exercise, should be initiated early in the course of survivorship, with referral to specialists to optimize success. However, among adults who develop obesity or the metabolic syndrome and who do not respond to lifestyle therapy, medical intervention may be indicated to manage underlying pathology, such as growth hormone deficiency, or to mitigate risk factors of cardiovascular disease. Because no specific clinical trials have been done in this population to treat metabolic syndrome or its components, clinicians who follow adult survivors of childhood ALL should use the existing American Heart Association/National Heart Lung and Blood Institute Scientific Statement to guide their approach.

MR imaging of the femoral marrow was performed in 36 patients with untreated acute myeloid leukemia (AML) and 7 patients with acute lymphocytic leukemia (ALL). The MRI appearance was classified into five patterns: fatty marrow; faint signal; nodular pattern; heterogeneous infiltration; and diffuse infiltration. The MRI patterns of the femoral marrow were compared among the FAB subtypes of acute leukemia, and the MRI patterns were correlated with prognosis. All five MRI patterns were observed in the femoral marrow in adult acute leukemia, and diffuse infiltration was most commonly seen (41.9%). A completely fatty marrow was also depicted in two cases (4.7%) and faint signal in four cases (9.3%) in spite of untreated acute leukemia. The M2 subtype of AML tended to be demonstrated as a minimally abnormal MRI finding, which was significantly different from the other types of AML. The patients who showed fatty marrow or faint signal were thought to have a good prognosis, while diffuse or heterogeneous infiltration was regarded as a poor prognostic sign. However, there were some exceptions to these rules, and no significant differences were revealed in prognosis between minimally abnormal and advanced MRI patterns. We concluded that MRI of the femoral marrow could be useful in the assessment of tumor volume of adult acute leukemia, and that there were limitations to predicting prognosis on the basis of the MRI manifestations.

However, for those in the adolescent and young adult (AYA age-group of 15–30 years with ALL, there has not been the same degree of improvement. Historically, pediatric and adult providers have utilized different treatment approaches based on clinical trials. However, studies that have compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have generally shown substantially better outcomes for this patient population treated with the pediatric trials. Additionally, hematopoietic stem cell transplantation has been considered as part of intensified therapy for AYA patients with ALL. Herein, we review the outcomes with chemotherapy alone and with hematopoietic stem cell transplantation, and explore the challenges faced in determining the ideal therapy for the AYA population of patients.

We performed a nationwide questionnaire-based survey to evaluate the current clinical practices of infectious complications during chemotherapy for acute leukemia in Japan. We e-mailed a questionnaire to member institutions of the Japan Adult Leukemia Study Group in September, 2013. The questionnaire consisted of 50 multiple-choice questions covering therapeutic environment, antimicrobial prophylaxis, screening test during neutropenia, empirical therapy for febrile neutropenia, and the use of granulocyte-colony stimulating factor. The results were compared to those of previous surveys conducted in 2001 and 2007, and also to the recommendations described in the guidelines. Usable responses were received from 141 out of 222 (63.5%) institutions. Chemotherapy for acute myeloid leukemia was performed in protective environment in 90% of the institutions, which increased compared to previous survey (76%). Fluoroquinolones and fluconazole were the most commonly used antimicrobial agents for antibacterial and antifungal prophylaxis, followed by sulfamethoxazole-trimethoprim and itraconazole, respectively. In empirical therapy for febrile neutropenia, monotherapy with β-lactum antibiotics was the first-line therapy in most of the institutions. While empirical antifungal therapy was adopted for persistent fever in more than half of the institutions, preemptive/presumptive therapy was also used in approximately 40% of the institutions. Most of the clinicians were reluctant to use granulocyte-colony stimulating factor routinely in chemotherapy for acute myeloid leukemia. This study clarified the current clinical practices of infectious complications during chemotherapy for acute leukemia and would provide important information for the development of a suitable guideline in Japan.

The human T cell leukemia virus-1 (HTLV-1) oncoprotein Tax drives cell proliferation and resistance to apoptosis early in the pathogenesis of adult T-cell leukemia (ATL). Subsequently, likely as a result of specific immuno-editing, Tax expression is downregulated and functionally replaced by somatic driver mutations of the host genome. Both amplification and point mutations of interferon regulatory factor 4 (IRF4) have been previously detected in ATL, and the K59R mutation is the most common single-nucleotide variation in IRF4 and is found exclusively in ATL. Here high throughput whole-exome sequencing revealed recurrent activating genetic alterations in the T cell receptor, CD28, and NF-kB pathways. Moreover, we found that IRF4, which is transcriptionally activated downstream of these pathways, is frequently mutated in ATL. IRF4 RNA, protein, and IRF4 transcriptional targets are uniformly elevated in HTLV transformed cells and ATL cell lines, and IRF4 was bound to genomic regulatory DNA of many of these transcriptional targets in HTLV-1 transformed cell lines. We further noted that the K59R IRF4 mutant is expressed at higher levels in the nucleus than is wild-type IRF4, and is transcriptionally more active. Expression of both wild-type and the K59R mutant of IRF4 from a constitutive promoter in retrovirally transduced murine bone marrow cells increased the abundance of T lymphocytes but not myeloid cells or B lymphocytes in mice. IRF4 may represent a therapeutic target in ATL since ATL cells select for a mutant of IRF4 with higher nuclear expression and transcriptional activity, and over-expression of IRF4 induces the expansion of T lymphocytes in vivo.

Occupational and industrial exposures have been implicated in the etiology of leukemia, yet uncertainty remains regarding potential high risk occupations. We examined the associations between self-reported occupations and hobbies and acute leukemia risk using data from 811 cases and 637 controls participating in a case-control study in the U.S. and Canada. We found that several occupations may increase the risk of acute leukemia, particularly occupations related to petroleum products, rubber, nuclear energy, munitions, plastics, and electronics manufacturing. Differences were noted according to histological type. Other occupations and hobbies were not clearly associated with risk.

Infection of adult BALB/c mice with murine leukemia virus (MuLV) induces typical thymic lymphomas. Expression of virus was measured by using a radioimmunoassay for murine P-30, a virion core protein. Nineteen days after injection of MuLV-S into adult mice, there were 0.3μg P-30/ml of serum. X-irradiation permitted the early expression of high levels of viremia, when given before or after MuLV-S administration, and it also hastened the development of lymphomas. Seventeen to 21 days after injection of MuLV-S into x-irradiated (600 rads) adult mice, there were 2.7 μg of P-30/ml of serum. The virus produced by infected adult mice was infectious and oncogenic when given to newborn mice. Several lines of evidence are presented that suggest the mechanism by which x-irradiation permits early expession of virion proteins and lymphomas is not immunosuppression

Eight (88.9% patients, including two Philadelphia chromosome-positive ALL patients, achieved a complete remission. Furthermore, the evaluable patients have benefited from allo-HSCT after response to this reinduction treatment. We conclude that bortezomib-based chemotherapy was highly effective for adults with refractory/relapsed ALL before allo-HSCT.

Full Text Available Michael J BurkeDepartment of Pediatrics, Division of Hematology/Oncology/Bone Marrow Transplantation, Medical College of Wisconsin, Milwaukee, WI, USAAbstract: Using targeted therapy for treatment of cancer has become the paradigm to which clinical trials aspire. Imatinib, the BCR-ABL1 tyrosine kinase inhibitor (TKI, was the first of its kind to specifically target and inhibit the underlying Philadelphia chromosome (Ph+ oncogene found to be driving chronic myeloid leukemia in adults, and has since become standard of care for the treatment of chronic myeloid leukemia in children. Imatinib, with its ability to target Ph+ leukemia, has been successfully incorporated into the treatment of not only pediatric chronic myeloid leukemia but also Ph+ acute lymphoblastic leukemia. With the incorporation of imatinib into combination chemotherapy for pediatric Ph+ acute lymphoblastic leukemia, current survival rates are far higher than at any other time for this once dreadful disease. With more children today receiving treatment with imatinib for either chronic myeloid leukemia or Ph+ acute lymphoblastic leukemia, knowledge is accumulating surrounding the short-term and long-term toxicities observed in children, adolescents, and young adults treated with this TKI. In summary, the TKI imatinib has made a historic impact in the treatment of pediatric Ph+ leukemias, transforming what were once very high-risk diseases with considerable morbidity and mortality into ones that are now very treatable but with a new awareness surrounding the long-term toxicities that may come with this price for cure.Keywords: imatinib, leukemia, lymphoblastic leukemia, chronic myeloid leukemia, pediatric

Multiple lymphomatous polyposis (HLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL is reviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

Young adults accounted for 10-14% of ischemic stroke patients. The risk factors may differ in this population from elder patients. In addition, the factors associated with stroke recurrence in this population have not been well investigated. The study aimed to investigate the characteristics and risk factors associated with recurrence of ischemic stroke in young adults. Clinical data of 1,395 patients of age 18-45 years who were treated between 2008 and 2014 in 3 centers located in northern China was reviewed. The first onset of stroke was taken as the initial events and recurrent stroke as the end point events. The end point events, age, gender, duration after first onset of stroke, history of disease, National Institutes of Health Stroke Scale (NIHSS) score at admission, Trial of Org 10172 in Acute Stroke Treatment classifications of the cause of stroke and adherence to medication were recorded. These factors were analyzed and compared between recurrence and non-recurrence group. Information about recurrent stroke was collected through clinical (readmission to hospital with ischemic stroke) or telephone follow-up survey. Logistic regression was used to analyze the risk factors of recurrence. The most common causes of stroke were large vessel atherosclerosis and small vessel occlusion, followed by cardioembolism. NIHSS score at admission (OR 1.088; 95% CI 1.028-1.152; p = 0.004) were associated with recurrence. Vascular disease, especially premature atherosclerosis, is the major risk factor for ischemic stroke in the young adult population of northern China. Timely screening of the cause of stroke with severe NIHSS score needs further attention. © 2017 The Author(s) Published by S. Karger AG, Basel.

Patients with acute leukemia usually experience pain, fatigue, and sleep disorders, which affect their quality of life. Massage therapy, as a nondrug approach, can be useful in controlling such problems. However, very few studies have been conducted on the effects of massage therapy on the complications of leukemia. The aim of this study was to examine the effects of slow-stroke back massage (SSBM) on the symptom cluster in acute leukemia adult patients undergoing chemotherapy. In this randomized controlled trial, 60 patients with acute leukemia were allocated randomly to either the intervention or control group. The intervention group received SSBM 3 times a week (every other day for 10 minutes) for 4 weeks. The pain, fatigue, and sleep disorder intensities were measured using the numeric rating scale. The sleep quality was measured using the Pittsburgh Sleep Quality Index. Statistical tests of χ, t test, and the repeated-measure analysis of variance were used for data analysis. Results showed that the SSBM intervention significantly reduced the progressive sleep disorder, pain, fatigue, and improved sleep quality over time. Slow-stroke back massage, as a simple, noninvasive, and cost-effective approach, along with routine nursing care, can be used to improve the symptom cluster of pain, fatigue, and sleep disorders in leukemia patients. Oncology nurses can increase their knowledge regarding this symptom cluster and work to diminish the cluster components by using SSBM in adult leukemia patients.

Full Text Available The primary objective of this review was to update and discuss the current concepts andthe results of the treatment of acute lymphoblastic leukemia (ALL in adolescents and young adults(AYA. After a brief consideration of the epidemiologic and clinicobiologic characteristics of ALLin the AYA population, the main retrospective comparative studies stating the superiority ofpediatric over adult-based protocols were reviewed. The most important prospective studies inyoung adults using pediatric inspired or pediatric unmodified protocols were also reviewedemphasizing their feasibility at least up to the age of 40 yr and their promising results, with eventfreesurvival rates of 60-65% or greater. Results of trials from pediatric groups have shown that theunfavourable prognosis of adolescents is no more adequate. The majority of the older adolescentswith ALL can be cured with risk-adjusted and minimal residual disease-guided intensivechemotherapy, without stem cell transplantation. However, some specific subgroups, which aremore frequent in adolescents than in children (e.g., early pre-T, iAMP21, and BCR-ABL-like,deserve particular attention. In summary, the advances in treatment of ALL in adolescents havebeen translated to young adults, and that explains the significant improvement in survival of thesepatients in recent years.

Treatment of Adults with Idiopathic Recurrent Pericarditis: Novel Use of Immunotherapy.

Schwier, Nicholas C; Hale, Genevieve M; Davies, Marie L

2017-03-01

Idiopathic recurrent pericarditis (IRP) can be challenging to treat. Even after guideline-directed first-line treatment consisting of aspirin (ASA) or a nonsteroidal antiinflammatory drug (NSAID) in combination with colchicine therapy, recurrences still occur in greater than 20% of patients. Many patients then require treatment with long-term corticosteroids, which is not a favorable option due to their short- and long-term adverse effects. Because it is theorized that the pathophysiology of IRP may possess autoimmune sequelae, the use of immunotherapy for the treatment of IRP has emerged. In this review, we describe the literature associated with immunotherapy used to treat IRP in an adult population as well as provide an overview of the safety and monitoring parameters for each agent. The most common immunotherapies used after patients have had multiple recurrences of IRP are anakinra, intravenous immunoglobulin (IVIG), and azathioprine. In most cases, these immunotherapies are adjunctive therapy, with the goal of tapering and discontinuing immunosuppressive corticosteroids. After reviewing the data, anakinra resulted in more patients discontinuing corticosteroids and prevented further recurrences of pericarditis. IVIG resulted in symptom resolution and no further recurrences in most of the patients. Azathioprine was associated with more than half of patients becoming recurrence free; however, many patients required a restart of corticosteroids due to recurrence. Clinicians should be aware of the adverse effects of immunotherapy, ranging from mild gastrointestinal events to risk of infection and serious blood dyscrasias that may require diligent monitoring. The use of immunotherapy for the treatment of adults with IRP should be restricted to patients who have multiple recurrences. Ideally, immunotherapy would be adjunctive to first-line combination therapy with ASA/NSAID plus colchicine, with the goal of tapering and discontinuing immunosuppressive

In pediatric oncology, positron emission tomography/computed tomography (PET/CT) is emerging as an essential diagnostic tool in characterizing suspicious neoplastic lesions and staging malignant diseases. Most studies regarding the possible role of FDG-PET/CT in the management of acute lymphoblastic leukemia (ALL) patients are limited to adults. Here we report a pediatric patient with recurrent ALL, in which FDG-PET/CT was used both to define more precisely the cause of lymphadenopathy and to assess the effect of the second-line therapy.

The Southwest Oncology Group did a limited institutional pilot study of the combination of doxorubicin and ifosfamide in the treatment of previously treated adult patients with acute leukemia. Thirty-four patients received one or two courses of the combination. All patients had received prior chemotherapy and 32 had received prior anthracycline chemotherapy. Three patients died before their responses could be fully evaluated. Fourteen patients achieved complete remission (41%) and one patient achieved partial remission. The complete remission rate was 27% for patients with acute myeloblastic leukemia (myelomonoblastic leukemia, monoblastic leukemia, and erythroleukemia) and 89% for patients with acute lymphocytic and undifferentiated leukemia (ALL). Toxic effects included severe hematologic reactions in 33 of 34 patients, hematuria in six patients, altered sensorium in one patient, and congestive heart failure in one patient. The safety of the combination was established and toxic side effects of this therapy were tolerable. The 89% complete remission rate for previously treated patients with ALL suggests that the combination of doxorubicin and ifosfamide may be particularly effective in ALL.

Substantial interest in acute lymphoblastic leukemia (ALL) in young adults (YAs) and investigations focused on this patient population have resulted in therapeutic advancements that are changing the management paradigm and improving outcomes. The pediatric ALL approach is feasible and effective when administered by medical oncologists. Advanced diagnostics and minimal residual disease measurements aid in prognostication and have resulted in shifting recommendations regarding allogeneic hematopoietic cell transplant in first remission. Blinatumomab, inotuzumab, and chimeric antigen receptor T-cell therapies are transforming the treatment of relapsed/refractory ALL. This comprehensive review of the current management of ALL in YAs summarizes recent scientific developments and clinical trial findings related to ALL biology, frontline management approaches, novel therapies, and supportive care specific to this patient population. Finally, a practical guide to modern YA management for practicing clinicians is provided.

Full Text Available Introduction: Erythema nodosum (EN is the most common type of panniculitis. It may be idiopathic or secondary to various etiologies. However, the occurrence of erythema nodosum in malignant hemopathy had rarely been reported. Case report: A 42 year-old woman presented with a four week history of recurrent multiple painful erythematous nodules developed on the lower limbs associated with arthralgia of the ankles and fever. The clinical features of skin lesions with contusiform color evolution allowed establishing the diagnosis of EN. No underlying cause was found. The skin lesions were improved with non-steroidal anti-inflammatory drugs and colchicine. Three months later, the patient consulted for recurrence of EN associated with fever, inflammatory polyarthralgia and hepatosplenomegaly. The peripheral blood count revealed pancytopenia. A bone marrow examination confirmed the diagnosis of acute myeloid leukemia type 2. Initiation of chemotherapy was followed by the complete disappearance of skin lesions of EN. Conclusion: Paraneoplastic erythema nodosum is a rare entity. In the literature, a few cases of association with leukemia have been reported. Exploration for solid neoplasms or hemopathy in case of recurrent EN or resistance to conventional treatment should be systematic

Although the survival rate for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) has steadily improved over the past several decades, it still lags behind that of younger children. This Review explores the reasons for this discrepancy and potential solutions, focusing on patients aged 15-22 years. Recent studies that compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have shown substantially better outcomes for this patient population obtained with the pediatric trials. Excellent early results have been obtained for patients with ALL aged up to 40-60 years who were treated in adult study groups with pediatric-based regimens. Targeting biological and socio-political features unique to AYA ALL has reduced the 'AYA gap' and has provided the foundation for basic science and translational and clinical AYA initiatives that are charged with the task of discovering further methods to improve the outcome of AYA with ALL.

Adult T-cell leukemia (ATL) is a fatal lymphoproliferative disease that develops in human T-cell leukemia virus type I (HTLV-I)-infected individuals. Despite the accumulating knowledge of the molecular biology of HTLV-I-infected cells, effective therapeutic strategies remain to be established. Recent reports showed that the hydroxyl-3-methylglutaryl (HMG)-CoA reductase inhibitor statins have anti-proliferative and apoptotic effects on certain tumor cells through inhibition of protein prenylation. Here, we report that statins hinder the survival of ATL cells and induce apoptotic cell death. Inhibition of protein geranylgeranylation is responsible for these effects, since simultaneous treatment with isoprenoid precursors, geranylgeranyl pyrophosphate or farnesyl pyrophosphate, but not a cholesterol precursor squalene, restored the viability of ATL cells. Simvastatin inhibited geranylgeranylation of small GTPases Rab5B and Rac1 in ATL cells, and a geranylgeranyl transferase inhibitor GGTI-298 reduced ATL cell viability more efficiently than a farnesyl transferase inhibitor FTI-277. These results not only unveil an important role for protein geranylgeranylation in ATL cell survival, but also implicate therapeutic potentials of statins in the treatment of ATL

About one half of adults with acute lymphoblastic leukemia are not cured of the disease and ultimately die. The objective of this study was to explore the factors influencing the outcome of adult patients with relapsed acute lymphoblastic leukemia. We analyzed the characteristics, the outcome and the prognostic factors for survival after first relapse in a series of 263 adult patients with acute lymphoblastic leukemia (excluding those with mature B-cell acute lymphoblastic leukemia) prospectively enrolled in four consecutive risk-adapted PETHEMA trials. The median overall survival after relapse was 4.5 months (95% CI, 4-5 months) with a 5-year overall survival of 10% (95% CI, 8%-12%); 45% of patients receiving intensive second-line treatment achieved a second complete remission and 22% (95% CI, 14%-30%) of them remained disease free at 5 years. Factors predicting a good outcome after rescue therapy were age less than 30 years (2-year overall survival of 21% versus 10% for those over 30 years old; P<0.022) and a first remission lasting more than 2 years (2-year overall survival of 36% versus 17% among those with a shorter first remission; P<0.001). Patients under 30 years old whose first complete remission lasted longer than 2 years had a 5-year overall survival of 38% (95% CI, 23%-53%) and a 5-year disease-free survival of 53% (95% CI, 34%-72%). The prognosis of adult patients with acute lymphoblastic leukemia who relapse is poor. Those aged less than 30 years with a first complete remission lasting longer than 2 years have reasonable possibilities of becoming long-term survivors while patients over this age or those who relapse early cannot be successfully rescued using the therapies currently available.

Adult T-cell Leukemia/Lymphoma (ATLL) is an aggressive neoplasm of T lymphocytes associated with Human T-lymphotropic virus type1 (HTLV-1) infection. HTLV-1 is a public health problem because it is endemic in native groups in Latin America, and its infection leads to several chronic diseases as ATLL. We aimed to review current literature of ATLL in order to consider it as a differential diagnosis in front of patients with compatible symptoms. Prognosis is still poor in aggressive and indolent variants, with survival rates from months to few years. Treatment based on chemotherapy, antiretroviral, and allogenic stem cell transplantation are currently improving survival rates, but with limited results. Copyright © 2017 AEDV.

Full Text Available Translocation t(4;11(q21;q23 leading to formation of MLL-AF4 fusion gene is found in about 10% of newly diagnosed B-cell acute lymphoblastic leukemia (ALL in adult patients. Patients expressing this chromosomal aberration present typical biological, immunophenotypic, and clinical features. This form of leukemia is universally recognized as high-risk leukemia and treatment intensification with allogeneic hematopoietic stem cell transplantation (HSCT in first complete remission (CR could be a valid option to improve prognosis, but data obtained from the literature are controversial. In this review, we briefly describe pathogenetic, clinical, and prognostic characteristics of adult t(4;11(q21;q23/MLL-AF4 positive ALL and provide a review of the clinical outcome reported by the most important cooperative groups worldwide.

Chromosomal translocations with breakpoints in T-cell receptor (TCR) genes are recurrent in T-cell malignancies. These translocations involve the TCRalphadelta gene (14q11), the TCRbeta gene (7q34) and to a lesser extent the TCRgamma gene at chromosomal band 7p14 and juxtapose T-cell oncogenes next to TCR regulatory sequences leading to deregulated expression of those oncogenes. Here, we describe a new recurrent chromosomal inversion of chromosome 7, inv(7)(p15q34), in a subset of patients with T-cell acute lymphoblastic leukemia characterized by CD2 negative and CD4 positive, CD8 negative blasts. This rearrangement juxtaposes the distal part of the HOXA gene cluster on 7p15 to the TCRbeta locus on 7q34. Real time quantitative PCR analysis for all HOXA genes revealed high levels of HOXA10 and HOXA11 expression in all inv(7) positive cases. This is the first report of a recurrent chromosome rearrangement targeting the HOXA gene cluster in T-cell malignancies resulting in deregulated HOXA gene expression (particularly HOXA10 and HOXA11) and is in keeping with a previous report suggesting HOXA deregulation in MLL-rearranged T- and B cell lymphoblastic leukemia as the key factor in leukaemic transformation. Finally, our observation also supports the previous suggested role of HOXA10 and HOXA11 in normal thymocyte development.

In this study, we correlated the results of concurrent molecular and cytogenetic detection of entity-defining translocations in adults with acute leukemia to determine the frequency of cryptic translocations missed by conventional cytogenetics (CC) and of recurrent, prognostically relevant translocations not detectable by multiplex reverse transcriptase-polymerase chain reaction (MRP). During a 5.5-year period, 442 diagnostic acute leukemia specimens were submitted for MRP-based detection of 7 common recurrent translocations: t(8;21), t(15;17), inv(16), t(9;22), t(12;21), t(4;11), and t(1;19), with a detection rate of 15.2% (67/442). CC was performed in 330 (74.7%) of 442 cases. In 7 of these 330 cases, CC missed the translocation detected by MRP. In 50 additional cases, CC revealed 1 of the MRP-detectable translocations (all were also MRP positive), yielding a false-negative rate of 12% (7/57) for the CC assay. The remaining 140 of 190 cases with clonal cytogenetic changes harbored abnormalities that were not targeted by the MRP assay, including 8 that define specific acute myeloid leukemia entities. This study revealed the frequent occurrence of false-negative, entity-defining CC analysis and highlighted the complementary nature of MRP and CC approaches in detecting genetic abnormalities in acute leukemia.

Safety, efficacy, and clinical utility of asparaginase in the treatment of adult patients with acute lymphoblastic leukemia

Full Text Available Jamie Koprivnikar, James McCloskey, Stefan Faderl Division of Leukemia, John Theurer Cancer Center at Hackensack University Medical Center, Hackensack, NJ, USA Abstract: Adults with acute lymphoblastic leukemia (ALL are known to have inferior outcomes compared to the pediatric population. Although the reasons for this are likely manyfold, the agents utilized and the increased intensity of pediatric treatments compared to adult treatments are likely significant contributing factors. Asparaginase, an enzyme that converts asparagine to aspartic acid, forms the backbone of almost all pediatric regimens and works by depleting extracellular asparagine, which ALL cells are unable to synthesize. Asparaginase toxicities, which include hypersensitivity reactions, pancreatitis, liver dysfunction, and thrombosis, have hindered its widespread use in the adult population. Here, we review the toxicity and efficacy of asparaginase in adult patients with ALL. With the proper precautions, it is a safe and effective agent in the treatment of younger adults with ALL with response rates in the frontline setting ranging from 78% to 96%, compared to most trials showing a 4-year overall survival of 50% or better. The age cutoff for consideration of treatment with pediatric-inspired regimens is not clear, but recent studies show promise particularly in the adolescent and young adult population. New formulations of asparaginase are actively in development, including erythrocyte-encapsulated asparaginase, which is designed to minimize the toxicity and improve the delivery of the drug.

We previously reported that 9-methylstreptimidone, a piperidine compound isolated from a culture filtrate of Streptomyces, induces apoptosis selectively in adult T-cell leukemia cells. It was screened for a compound that inhibits LPS-induced NF-kappaB and NO production in mouse macrophages. However, 9-methystreptimidone is poorly obtained from the producing microorganism and difficult to synthesize. Therefore, in the present research, we studied the structure-activity relationship to look for new selective inhibitors. We found that the structure of the unsaturated hydrophobic portion of 9-methylstreptimidone was essential for the inhibition of LPS-induced NO production. Among the 9-methylstreptimidone-related compounds tested, (+/-)-4,alpha-diepi-streptovitacin A inhibited NO production in macrophage-like cells as potently as 9-methylstreptimidone and without cellular toxicity. Moreover, this compound selectively induced apoptosis in adult T-cell leukemia MT-1 cells.

Pathogenesis and treatment of leukemia: an Asian perspective.

Science.gov (United States)

Kwong, Yok-Lam

2012-03-01

Leukemias occur worldwide, but there are important geographic differences in incidences. Three leukemias with special Asian perspectives, acute promyelocytic leukemia (APL), T-cell large granular lymphocyte (T-LGL) leukemia and NK-cell leukemia. In APL, China has made contributions in discovering the efficacy of all-trans retinoic acid (ATRA) and arsenic trioxide. Some APL patients are potentially curable after treatment with ATRA or arsenic trioxide as a single agent. Combined treatment of APL with ATRA and arsenic trioxide induces remission with deeper molecular response. An oral formulation of arsenic trioxide is available, making outpatient treatment feasible. Future regimens for APL should examine how ATRA and arsenic trioxide can be optimally combined with other synergistic drugs. Asian patients with T-LGL leukemia present more frequently with pure red cell aplasia, but less frequently with neutropenia, recurrent infection, splenomegaly and rheumatoid arthritis as compared with Western patients. These differences have potential effects on treatment and disease pathogenesis. NK-cell leukemia is rapidly fatal and occurs almost exclusively in Asian and South American patients. Conventional anthracycline-based chemotherapy designed for B-cell lymphomas do not work in NK-cell leukemias. Novel therapeutic approaches targeting cellular signaling pathways or preferentially upregulated genes are needed to improve outcome.

Reanalysis of atomic bomb survivors' leukemia based on the recent classification for leukemias

1990-01-01

Four hundred and ninety-three A-bomb survivors developing leukemia, who had been exposed within 9,000 m from the hypocenter, were entered on the study for reanalysis of their disease based on the new classification. Chronic myelocytic leukemia (CML) showed the highest concordance rate (95%) between the previous and new classifications. For 10 survivors previously diagnosed as having chronic lymphocytic leukemia (CLL), a new classification diagnosed CLL as well in 3 and adult T-cell leukemia in the other 7. None of the A-bomb survivors exposed to one Gy or more had subtype M3 of acute myelocytic leukemia (AML), although the exposed group had almost the same distribution pattern of AML subtypes as the naturally induced leukemic group. The incidence of CML was significantly lower than that of AML in Nagasaki A-bomb survivors. As A-bomb survivors were older at the time of A-bombing, the relative risk of acute lymphoblastic leukemia (ALL) was decreased; that of CML and other types of leukemia was increased. An increased relative risk of ALL and CML tended to be associated with larger doses. A significantly shortened interval between A-bomb exposure and the development of leukemia was also associated with larger doses. (N.K.)

The Basel experience with total body irradiation for conditioning patients with acute leukemia for allogenic bone marrow transplantation

Speck, B.; Cornu, P.; Nissen, C.; Gratwohl, A.; Sartorius, J.

1979-01-01

We are reporting our experience with 13 patients suffering from end stage acute leukemia that were prepared for allogeneic bone marrow transplantation by combined chemotherapy followed by high dose cyclophosphamide (Cy) and total body irradiation (TBI). Only one patient became a long term survivor. Of the evaluable 12 patients, 6 died of interstitial pneumonia, 4 of GvH and 1 of recurrent leukemia. We conclude that adding combined chemotherapy to the standard conditioning program with Cy and TBI probably increases the risk of developing fatal interstitial pneumonia without eliminating the risk of recurrent leukemia. We suggest that allogenic marrow grafts should be performed earlier in the course of refractory acute leukemias, because in patients with end stage disease its chances of being curative are small

Multiple cytogenetic subgroups have been described in adult Philadelphia chromosome (Ph)-negative B-cell precursor (BCP) acute lymphoblastic leukemia (ALL), often comprising small numbers of patients. In this study, we aimed to reassess the prognostic value of cytogenetic abnormalities in a large series of 617 adult patients with Ph-negative BCP-ALL (median age, 38 years), treated in the intensified Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003/2005 trials. Combined data from karyotype, DNA index, fluorescence in situ hybridization, and polymerase chain reaction screening for relevant abnormalities were centrally reviewed and were informative in 542 cases (88%), allowing classification in 10 exclusive primary cytogenetic subgroups and in secondary subgroups, including complex and monosomal karyotypes. Prognostic analyses focused on cumulative incidence of failure (including primary refractoriness and relapse), event-free survival, and overall survival. Only 2 subgroups, namely t(4;11)/ KMT2A-AFF1 and 14q32/ IGH translocations, displayed a significantly worse outcome in this context, still observed after adjustment for age and after censoring patients who received allogeneic stem cell transplantation (SCT) in first remission at SCT time. A worse outcome was also observed in patients with low hypodiploidy/near triploidy, but this was likely related to their higher age and worse tolerance to therapy. The other cytogenetic abnormalities, including complex and monosomal karyotypes, had no prognostic value in these intensive protocols designed for adult patients up to the age of 60 years. © 2017 by The American Society of Hematology.

The etiology of leukemia is largely unknown. Ecological data indicating trends in incidence and survival can provide information about changes in risk factors, can reflect underlying changes in diagnostic classification, and can measure therapeutic advances. From the records of the Danish Cancer...... Registry with registration starting from 1943, we calculated age-specific, period-specific, and age-standardized (world standard) incidence rates of chronic lymphoid leukemia (CLL), acute lymphoid leukemia (ALL), chronic myeloid leukemia (CML), and acute myeloid leukemia (AML) for persons above the age...... of 18. Kaplan-Meier survival curves and median survival times were calculated. Between 1943 and 2003, there were 26,036 cases of leukemia reported. The age-specific incidence rates of CLL, CML, and AML were higher for older men and women, while the incidence rates of ALL by age were more homogeneous...

Sixteen adult patients with acute leukemia treated by chemotherapy, total body irradiation and allogeneic marrow transplantation

Since 1976, 16 adult patients with acute leukemia have been treated by chemotherapy, total body irradiation (TBI) and allogeneic bone marrow transplantation (BMT) in the medical school hospital and the satellite hospitals of Nagoya University. The first group of 10 patients were given marrow grafts at the time of leukemic relapse and the second group of six patients were given the grafts in the period of remission of their disease. For the first group (ALL/ANLL 2:8, age (median) 33, M/F 8:2), HLA-identical donor cells (25 x 10/sup 7//kg(median)) were infused after the patients were conditioned with NSC D 245382 (ACNU) or daunorubicin, cyclophosphamide (CY) and a single shot of 1000 rad of TBI. For the second group (ALL/ANLL 4:2, age (median) 20, M/F 5:1), HLA-identical donor cells (22 x 10/sup 7//kg(median)) were infused after the patients were conditioned with CY and fractionated (250 rad x 4) TBI. All the patients were isolated in a laminar air flow room (LAF) after gut and skin decontamination. Engraftment of donor cells was confirmed in 15 out of the 16 patients. Febrile periods in LAF and the days required for platelet transfusion were prolonged in the first group. All the patients in the first group died within 12-214 days after BMT because of interstitial pneumonitis (7 patients) or bacterial infection (3 patients). On the other hand, five out of six patients in the second group are alive 84-540 days after BMT. For the surviving patients, the complications of chronic graft versus host disease, viral infections, tuberculosis, hepatitis, hemorrhagic cystitis and recurrence of leukemia are now the problems. It can be stated that the patient's clinical condition at the time of BMT is one of the most essential factors for the success of BMT although the effects of other variables, such as a change in the conditioning regimens or the supportive care, must also be carefully analyzed.

Adolescents and young adults (AYAs, 15-39 years) with acute lymphoblastic leukemia (ALL) represent a heterogeneous population who receive care in pediatric or adult cancer settings. Using the California Cancer Registry, we describe AYA ALL patterns of care and outcomes over the past decade. Sociodemographics, treatment location, and front-line therapies administered to AYAs diagnosed with ALL between 2004 and 2014 were obtained. Cox regression models evaluated associations between ALL setting and regimen and overall survival (OS) and leukemia-specific survival (LSS) for the entire cohort, younger AYA (<25 years), and AYAs treated in the adult cancer setting only. Of 1473 cases, 67.7% were treated in an adult setting; of these, 24.8% received a pediatric ALL regimen and 40.7% were treated at a National Cancer Institute (NCI)-designated center. In multivariable analyses, front-line treatment in a pediatric (vs adult) setting (OS HR = 0.53, 95% confidence interval [CI], 0.37-0.76; LSS HR = 0.51, 95% CI, 0.35-0.74) and at an NCI/Children's Oncology Group (COG) center (OS HR = 0.80, 95% CI, 0.66-0.96; LSS HR = 0.80, 95% CI, 0.65-0.97) were associated with significantly superior survival. Results were similar when analyses were limited to younger AYAs. Outcomes for AYAs treated in an adult setting did not differ following front-line pediatric or adult ALL regimens. Our population-level findings demonstrate that two-thirds of AYAs with newly diagnosed ALL are treated in an adult cancer setting, with the majority receiving care in community settings. Given the potential survival benefits, front-line treatment of AYA ALL at pediatric and/or NCI/COG-designated cancer centers should be considered. © 2018 by The American Society of Hematology.

RBP2 Promotes Adult Acute Lymphoblastic Leukemia by Upregulating BCL2.

Directory of Open Access Journals (Sweden)

Xiaoming Wang

Full Text Available Despite recent increases in the cure rate of acute lymphoblastic leukemia (ALL, adult ALL remains a high-risk disease that exhibits a high relapse rate. In this study, we found that the histone demethylase retinoblastoma binding protein-2 (RBP2 was overexpressed in both on-going and relapse cases of adult ALL, which revealed that RBP2 overexpression was not only involved in the pathogenesis of ALL but that its overexpression might also be related to relapse of the disease. RBP2 knockdown induced apoptosis and attenuated leukemic cell viability. Our results demonstrated that BCL2 is a novel target of RBP2 and supported the notion of RBP2 being a regulator of BCL2 expression via directly binding to its promoter. As the role of RBP2 in regulating apoptosis was confirmed, RBP2 overexpression and activation of BCL2 might play important roles in ALL development and progression.

Full Text Available Objective: This study investigated the occurrence of the p190 and p210 break point clusterregion-Abelson (BCR-ABL rearrangements in adults with acute lymphoblastic leukemia and possible associations with clinical and laboratory characteristics and survival. Methods: Forty-one over 18-year-old patients with acute lymphoblastic leukemia of both genders followed-up between January 2008 and May 2012 were included in this study. Clinical and laboratory data were obtained from the medical charts of the patients. Reverse transcription polymerase chain reaction (RT-PCR using specific primers was employed to identify molecular rearrangements. Results: At diagnosis, the median age was 33 years, and there was a predominance of males (61%. The most common immunophenotype was B lineage (76%. BCR-ABL rearrangements was detected in 14 (34% patients with the following distribution: p190 (28%, p210 (50% and double positive (22%. Overall survival of patients with a mean/median of 331/246 days of follow up was 39%, respectively, negative BCR-ABL (44% and positive BCR-ABL (28%. Conclusion: These results confirm the high frequency of BCR-ABL rearrangements and the low survival rate of adult Brazilian patients with acute lymphoblastic leukemia.

Adult T-cell leukemia/lymphoma (ATLL) is a generally fatal malignancy. Most ATLL patients fare poorly with conventional chemotherapy; however, antiviral therapy with zidovudine (AZT) and interferon alpha (IFN-α) has produced long-term clinical remissions. We studied primary ATLL tumors and identified molecular features linked to sensitivity and resistance to antiviral therapy. Enhanced expression of the proto-oncogene c-Rel was noted in 9 of 27 tumors. Resistant tumors exhibited c-Rel (6 of 1...

A case of acute nonlymphocytic leukemia presenting as pericarditis is reported in a five-year-old boy. Initially, a clinical diagnosis of viral pericarditis was made, because the child did not demonstrate hematologic or clinical manifestations of leukemia. Acute undifferentiated or lymphocytic leukemia. Acute undifferentiated or lymphocytic leukemia was diagnosed one week after admission when his peripheral blood count became abnormal. The patient did not respond to vincristine and prednisone. When cytochemical evaluation indicated acute myelomonocytic leukemia, employment of cytosine arabinoside and 6-thioguanine was instituted and the child began to improve. Currently, he is still in good remission and has no evidence of recurrence of pericarditis, 1 1/2 years after his initial presentation. In reviewing the literature, we found 17 patients who had leukemic pericardial effusion with cardiac tamponade. There are three reported cases of young children with pericardial effusion as the initial manifestation of acute lymphocytic leukemia, but no reported cases due to nonlymphocytic leukemia, as in this child.

For adults with acute leukemia, it is important to know whether the therapeutic schemes initially planned were actually implemented. The European Group for Blood and Marrow transplantation Acute Leukemia Working Party prospectively followed 695 consecutive patients who were registered at the time of HLA typing. Of 304 patients with an available matched sibling donor (MSD), SCT was planned in 264, chemotherapy in 33 and autografting in 7. For the rest, an unrelated donor (UD) search was initiated in 198. Among these, 117 were transplanted, 114 received chemotherapy and 77 underwent autografting. Probabilities of receiving a planned treatment were 60 and 65% at 1 and 2 years, respectively. Patients scheduled to receive MSD SCT had an 82% probability, whereas those scheduled to undergo UD SCT had a 57% probability, of receiving their transplant at 1 year. The only factor associated with a lower probability of MSD SCT in first remission was delayed HLA typing (HR=0.82; P=0.03). One year after enrollment, 40% of patients did not follow their initial treatment plan. Because OS was 50% only at 3 years and only 57% of the patients without a MSD underwent SCT, this suggests room for improvement in outcomes for adults with acute leukemia.

Although better nutritional support has improved the growth rates in children, the occurrence of primary spontaneous pneumothorax has also been increasing in children. The current study attempts to investigate the occurrence and recurrence of primary spontaneous pneumothorax and the efficacy of surgery for primary spontaneous pneumothorax in young adults and children. A total of 840 patients were treated for pneumothorax at our hospital from January 2006 to December 2010. Exclusion criteria for this study were age >25 or secondary, traumatic or iatrogenic pneumothorax, and a total of 517 patients were included. Patients were classified into three groups according to age at the first episode of primary spontaneous pneumothorax: Group A: ≤16 years; Group B: 17-18 years and Group C: ≥19 years. The study group was composed of 470 male and 47 female patients. There were 234 right-sided, 279 left-sided and 4 bilateral primary spontaneous pneumothoraces. Wedge resection by video-assisted thoracic surgery was performed in 285 patients, while 232 were managed by observation or closed thoracostomy. In the wedge resection group, 51 patients experienced recurrence. The recurrence rates after wedge resection were 27.9% in Group A, 16.5% in Group B and 13.2% in Group C (P = 0.038). The recurrence rates after observation or closed thoracostomy were 45.7% in Group A, 51.9% in Group B and 47.7% in Group C (P = 0.764). In the present study, postoperative recurrence rates were higher than those in the literature. Intense and long-term follow-up was probably one reason for the relatively high recurrence rate. The recurrence rate after wedge resection in patients aged ≤16 years was higher than that in older patients. There was no difference between the recurrence rates after observation or closed thoracostomy, regardless of age. These results suggest that wedge resection might be delayed in children. © The Author 2015. Published by Oxford University Press on behalf of the

A case of acute lymphoblastic leukemia with abnormal brain CT scan after cranial irradiation for central nervous system leukemia

International Nuclear Information System (INIS)

Sato, Junko; Abe, Takanori; Watanabe, Tsutomu

1988-01-01

A 21-year-old woman with acute lymphoblastic leukemia presented with central neurologic symptoms immediately after the second irradiation (20 Gy to the brain and 10 Gy to the spinal cord) for central nervous system (CNS)-leukemia 3 years and 2 months after the first cranial irradiation with 20 Gy. White matter was depicted as diffusely high density area on CT; histology revealed necrosis of leukemic cells. In the present patient with repeated recurrent CNS-leukemia, leukemic cells seemed to have been damaged simultaneously after irradiation because of parenchymal widespread involvement of leukemic cells, resulting in brain edema, an increased intracranial pressure and parenchymal disturbance. This finding may have an important implication for the risk of cranial irradiation in the case of widespread involvement of leukemic cells. Re-evaluation of cranial irradiation in such cases is suggested. (Namekawa, K.)

The transplantation of human cancer cells into immunodeficient NOD/SCID/IL-2Rγc(null) (NOG) mice often causes highly malignant cell populations like cancer stem cells to emerge. Here, by serial transplantation in NOG mice, we established two highly tumorigenic adult T-cell leukemia-derived cell lines, ST1-N6 and TL-Om1-N8. When transplanted s.c., these cells formed tumors significantly earlier and from fewer initial cells than their parental lines ST1 and TL-Om1. We found that protein kinase B (AKT) signaling was upregulated in ST1-N6 and TL-Om1-N8 cells, and that this upregulation was due to the decreased expression of a negative regulator, INPP5D. Furthermore, the introduction of a constitutively active AKT mutant expression vector into ST1 cells augmented the tumorigenicity of the cells, whereas treatment with the AKT inhibitor MK-2206 attenuated the progression of tumors induced by ST1-N6 cells. Collectively, our results reveal that the AKT signaling pathway plays a critical role in the malignancy of adult T-cell leukemia-derived cells. © 2016 The Authors.

The prognosis, in the long term, of adolescents and young adults with acute de novo lymphoblastic leukemia, treated with a pediatric type protocol. To analyze the efficacy and tolerability of a chemotherapy regimen of pediatric type on patients 15-35 years old with de novo acute lymphoblastic leukemia, Ph(-). A retrospective study of patients received from 2001 to 2013, without initial infiltration of the central nervous system. They received the regimen called LALÍN. Terminal goals: frequency of initial remission, probability of survival free of leukemia and event-free survival for five years. We included 101 patients; there were 29 relapses and 19 deaths. There was initial remission in 97% of the cases; survival free of leukemia of 0.58 and event-free survival 0.44. No difference in patients aged 16-21 years vs. 22-35 (p > 0.55). Negative prognostic factors: abnormal karyotypes, except hyperdiploids (p = 0.001); > 5% of blasts, on 14 day induction (p = 0. 0001); delay in the punctuality of the courses of the chemotherapy regimen (p = 0.0001). A pediatric type regimen is applicable to patients aged from 16 to 35 years with acute lymphoblastic leukemia, without greater toxicity and a best survival free of leukemia. The count of > 5% of blasts and the delay in the execution of the stages of the chemotherapy regimen are the stronger negative prognostic factors.

Interrogate the impact of IKZF1 deletion on therapy-outcomes of adults with common B-cell acute lymphoblastic leukemia. One hundred sixty-five consecutive adults with common B-cell ALL were tested for IKZF1 deletion and for BCR/ABL. Deletions in IKZF1 were detected using multiplex RQ-PCR, multiplex fluorescent PCR, sequence analysis and multiplex ligation-dependent probe amplification (MLPA). BCR/ABL was detected using RQ-PCR. All subjects received chemotherapy and some also received an allotransplant and tyrosine kinase-inhibitors. Multivariate analyses were done to identify associations between IKZF1 deletion and other variables on non-relapse mortality (NRM), cumulative incidence of relapse (CIR), leukemia-free survival (LFS) and survival. Amongst subjects achieving complete remission those with IKZF1 deletion had similar 5-year non-relapse mortality (NRM) (11% [2-20%] vs. 16% [4-28%]; P = 0.736), a higher 5-year cumulative incidence of relapse (CIR) (55% [35-76%] vs. 25% [12-38%]; P = 0.004), and worse 5-year leukemia-free survival (LFS) (33% [16-52%] vs. 59% [42-73%]; P = 0.012) and survival (48% [33-62%] vs. 75% [57-86%]; P = 0.002). In multivariate analyses IKZF1 deletion was associated with an increased relapse (relative risk [RR] =2.7, [1.4-5.2]; P = 0.002), a higher risk of treatment-failure (inverse of LFS; RR = 2.1, [1.2-3.6]; P = 0.007) and a higher risk of death (RR = 2.8, [1.5-5.5]; P = 0.002). The adverse impact of IKZF1 deletion on outcomes was stronger in subjects without vs. with BCR-ABL1 and in subjects receiving chemotherapy-only vs. an allotransplant. IKZF1 deletion was independently-associated with a higher relapse risk and worse LFS and survival in adults with common B-cell ALL after adjusting for other prognostic variables and differences in therapies. These data suggest IKZF1 deletion may be a useful prognostic variable in adults with common B-cell ALL, especially in persons without BCR-ABL1 and those receiving chemotherapy

Adult T-cell leukemia-lymphoma is a distinct type of peripheral T-cell lymphoma caused by human T-cell lymphotropic virus type I. Although allogeneic stem cell transplantation after chemotherapy is a recommended treatment option for patients with aggressive adult T-cell leukemia-lymphoma, there is no consensus about indications for allogeneic stem cell transplantation because there is no established risk stratification system for transplant eligible patients. We conducted a nationwide survey of patients with aggressive adult T-cell leukemia-lymphoma in order to construct a new, large database that includes 1,792 patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who were diagnosed between 2000 and 2013 and received intensive first-line chemotherapy. We randomly divided patients into two groups (training and validation sets). Acute type, poor performance status, high soluble interleukin-2 receptor levels (> 5,000 U/mL), high adjusted calcium levels (≥ 12 mg/dL), and high C-reactive protein levels (≥ 2.5 mg/dL) were independent adverse prognostic factors used in the training set. We used these five variables to divide patients into three risk groups. In the validation set, median overall survival for the low-, intermediate-, and high-risk groups was 626 days, 322 days, and 197 days, respectively. In the intermediate- and high-risk groups, transplanted recipients had significantly better overall survival than non-transplanted patients. We developed a promising new risk stratification system to identify patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who may benefit from upfront allogeneic stem cell transplantation. Prospective studies are warranted to confirm the benefit of this treatment strategy. Copyright© 2017 Ferrata Storti Foundation.

The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome. A total of 110 adult patients (34 ± 12 years) with ALL underwent TBI (6 fractions of 2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported. Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72 %, respectively. In all, 29 % (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22 %, and 60 and 52.7 %, respectively. The most frequent late reaction wascGVHD of the skin (n = 33, 30 %). In addition, 15.5 % (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110 = 28 %); 12 of 110 patients (11 %) presented with symptoms from osteoporosis, 5 of 110 patients (4.5 %) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11 % reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented. Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic

Our principal aim was to assess the occupational outcomes of French survivors of childhood leukemia, compared to national population. The secondary objective was to identify determinants linked with employment stability after childhood leukemia. All survivors aged 15 and over enrolled in the French LEA Cohort (Childhood and Adolescent Leukemia) were included. Occupational data were self-reported. The occupational distributions expected in the cohort for each age range were established based on the distribution in France as reference, and comparisons between observed and expected distributions were performed. Logistic regression model was used to explore determinants of stability of survivors' employment. The questionnaire was completed by 845 eligible survivors (response rate 87.8 %), with a mean age of 22.3 ± 5.4 years and a mean follow-up duration of 14.3 ± 6.3 years. Among the 361 survivors currently in the labor market, 36 (10.0 %) were seeking a job, which is significantly lower than expected (19.3 %) compared to French population. Conversely, among those currently employed, the number of survivors in unstable employment (43.9 %) was significantly higher than expected (33.5 %). Younger age and higher number of late effects were risk factors for unstable employment. While the employment rate of the young French adult population of childhood leukemia survivors seems rather positive, access to a steady job appears to be compromised for some survivors. A strategy to better identify particular subgroups of survivors at greatest risk for difficulties in their professional achievement will help ensure the development of specific intervention strategies and support procedures.

Sobel, Jack D; Funaro, Deana; Kaplan, Edward L

2007-03-01

Group A beta-hemolytic streptococcal (GAS) vulvovaginitis has been reported in prepubertal girls. In adult women, a vaginal carrier state has been described, but vulvovaginitis is rarely reported. We describe 2 cases of recurrent GAS vulvovaginitis in women whose husbands were gastrointestinal carriers of GAS. Characterization of the isolated strains demonstrated that identical emm types of GAS were shared by partners. Treatment of both partners resulted in resolution of vaginitis. On the basis of negative vaginal culture results obtained after treatment of each individual episode of vaginitis, we believe that the female patients were reinfected as a result of exposure to their husbands, with shedding likely to have occurred in bed. These cases reiterate the necessity for adequate screening of the patient's family and contacts in cases of recurrent GAS infection by culturing all potential areas of GAS carriage.

To analyze hematopoietic cell surface antigen reactivity in acute leukemia (AL) by flow cytometry and identify acute mixed-lineage leukemias (AMLL) employing the most widely accepted criteria. Ninety seven patients with de novo AL were studied. Cell surface antigens were investigated with monoclonal antibodies directed to: B lymphoid (CD10, CD19, CD20, CD21, CD22); T lymphoid (CD2, CD3, CD5, CD7); and myeloid (CD13, CD14, CD15, CD33, CD41) cell lineages. Maturation cell-associated antigens (CD34, HLA-DR and TdT) were also studied. Twelve patients unclassified by cytomorphology could be classified by immunophenotype. Using cytomorphologic, cytochemical and immunophenotypic data, 54 cases corresponded to acute lymphoblastic leukemia (ALL) and 43 were acute myeloblastic leukemia (AML). In All there were 63% B lineage, 15% T, 7% T/B, 6% undifferentiated and 9% mixed-lineage (coexpression of two or more myeloid-associated antigens). In AML, myeloid immunophenotype was observed in 86% undifferentiated in 2%, and mixed-lineage in 12% (coexpression of two or more lymphoid-associated antigens). In addition, 26% of ALL cases and 12% of AML cases expressed a single myeloid and lymphoid antigen respectively. The most common aberrant antigens in ALL and AML were CD13 and CD7 respectively. The highest frequency of CD34 antigen expression (90%) was detected in patients with AMLL. Flow cytometric immunophenotypic analysis allowed to: a) establish diagnosis in cytomorphologically unclassified cases; b) identify AMLL with a frequency similar to that reported in other series; and c) confirm the heterogeneity of AL.

The usefulness for clinical purposes of the distinction of acute undifferentiated (AUL) and acute lymphocytic leukemia (ALL) is suggested by the following observations: 1. Maturation from AUL to ALL has not been observed. Transformation of ALL to AUL has been reported i.e. less of cytoplasmic polysaccharides; however this seems rather to be the effect of cytotoxic therapy and not a real change of the cytological type. 2. Significant differences among ALL and AUL can be noted as far as the therapeutic response is concerned: All of the 9 patients with ALL but only 2 out of 9 patients with AUL went into remission. The mean survival of the cases with ALL amounts to 34, that of AUL only to 4 months. Out of the patients with ALL 4 patients are still alive in persistant first remission after 77, 57, 36 and 28 months. 3. ALL occurs most frequently in young adults (mean age of 21 patients: 31.7 years): AUL is more frequent in elderly patients (Mean age of 18 patients: 57.6 years). 4. In our material ALL did never occur consequent to a typical preluekemic stage, which was followed either by myeloblastic, monocytic, erythroleukemic or undifferentiated leukemias.

A 22-year-old male presented with recurrent, mild, unilateral left-sided epistaxis once to twice per month for 3 years. This usually occurred after minor nasal trauma or rubbing his nose. The patient also suffered from recurrent tonsillitis. There was neither history of blood transfusion or nasal packing, nor a history suggestive of bleeding diathesis. Anterior rhinoscopy revealed ivory white nasal mass antero-inferiorly in the left nasal cavity touching Little's area. There was no bleeding. Nasal endoscopy showed a white cylindrical bony mass 1 cm long arising from the floor of the nose, with no attachment to the nasal septum or the lateral wall of the nose. Examination of the right nasal cavity was unremarkable. Nasal teeth result from the ectopic eruption of supernumerary teeth and may cause a variety of symptoms including recurrent epistaxis. Their clinical and radiologic presentation is so characteristic that their diagnosis is not difficult. CT scan is helpful in planning management. Early extraction prevents further complications and prevents further attacks of epistaxis.

Leukemia and lymphoma in atomic bomb survivors

Leukemia has been observed to increase with increasing radiation dose in the A-bomb survivors of Hiroshima and Nagasaki. The first radiation-related cases occurred 3 to 5 years following exposure. The peak incidence years were about 7 to 8 years following exposure and the leukemogenic effect has decreased since that time, but it may last for 40 years or longer in the most heavily exposed persons. A bimodal susceptibility pattern was observed, with peaks following exposure during childhood and after age 50. Latent periods for the development of acute leukemia were shortest in the younger exposed persons. Both acute and chronic forms of leukemia occurred in exposed persons at younger ages in life than normally is expected. The most common types of radiation-induced leukemia were acute and chronic granulocytic in adults and children, and acute lymphocytic in children. The highest radiation-related leukemia risk was for chronic granulocytic leukemia following childhood exposure

The recent World Health Organization classification recognizes different subtypes of acute myeloid leukemia (AML) according to the presence of several recurrent genetic abnormalities. Detection of these abnormalities and other molecular changes is of increasing interest because it contributes to a refined diagnosis and prognostic assessment in AML and enables monitoring of minimal residual disease. These genetic abnormalities can be detected using single RT-PCR, although the screening is still labor intensive and costly. We have developed a novel real-time RT-PCR assay to simultaneously detect 15 AML-associated rearrangements that is a simple and easily applicable method for use in clinical diagnostic laboratories. This method showed 100% specificity and sensitivity (95% confidence interval, 91% to 100% and 92% to 100%, respectively). The procedure was validated in a series of 105 patients with AML. The method confirmed all translocations detected using standard cytogenetics and fluorescence in situ hybridization and some additional undetected rearrangements. Two patients demonstrated two molecular rearrangements simultaneously, with BCR-ABL1 implicated in both, in addition to RUNX1-MECOM in one patient and PML-RARA in another. In conclusion, this novel real-time RT-PCR assay for simultaneous detection of multiple AML-associated fusion genes is a versatile and sensitive method for reliable screening of recurrent rearrangements in AML.

Full Text Available Leukemia is the most common malignancy among all childhood cancers and is associated with a low survival rate in adult patients. Since 1995, the National Health Insurance (NHI program in Taiwan has been offering insurance coverage for Traditional Chinese Medicine (TCM, along with conventional Western medicine (WM. This study analyzes the status of TCM utilization in Taiwan, in both pediatric and adult patients with leukemia. A retrospective cohort study was conducted using population-based National Health Insurance Research Database of Registry of Catastrophic Illness, involving patient data from 2001 to 2010 and follow-up data through 2011. The effectiveness of TCM use was evaluated. Relevant sociodemographic data showed that both pediatric and adult patients who were TCM users one year prior to leukemia diagnosis were more likely to utilize TCM services for cancer therapy. A greater part of medical expenditure of TCM users was lower than that of TCM nonusers, except little discrepancy in drug fee of adult patients. The survival rate is also higher in TCM users. Altogether, these data show that TCM has the potential to serve as an adjuvant therapy when combined with conventional WM in the treatment of patients with leukemia.

The chromosomes of 12 adult patients with acute leukemia were analyzed by conventional means and by Giemsa and centromeric banding techniques. Acute myeloblastic leukemia was diagnosed in 7, acute myelomonocytic leukemia in 2, and acute undifferentiated leukemia in 3. Bone marrow was aspirated from patients when in relapse or remission, and both euploid and aneuploid cells were examined. All patients showed trisomy no. 9 and many showed additional numerical or structural changes in some or all their cells. These changes included monosomy no. 21 and/or monosomy no. 8. The proportion of trisomy no. 9 cells was 30-50% in patients in full remission and up to 100% in patients in relapse; thus trisomy no. 9 might be an important marker of leukemic cells. A mechanism was proposed to explain the induction and selection of the trisomy no. 9 karotype.

An increasing numbers of patients are being diagnosed with asymptomatic early-stage chronic lymphocytic leukemia (CLL), with no treatment indication at baseline. We applied a high-throughput deep-targeted analysis, especially designed for covering widely TP53 and ATM genes, in 180 patients with inactive disease at diagnosis, to test the independent prognostic value of CLL somatic recurrent mutations. We found that 40/180 patients harbored at least one acquired variant with ATM (n=17, 9.4%), NOTCH1 (n=14, 7.7%), TP53 (n=14, 7.7%) and SF3B1 (n=10, 5.5%) as most prevalent mutated genes. Harboring one ‘sub-Sanger' TP53 mutation granted an independent 3.5-fold increase of probability of needing treatment. Those patients with a double-hit ATM lesion (mutation+11q deletion) had the shorter median time to first treatment (17 months). We found that a genomic variable: TP53 mutations, most of them under the sensitivity of conventional techniques; a cell phenotypic factor: CD38-positive expression; and a classical marker as β2-microglobulin, remained as the unique independent predictors of outcome. The high-throughput determination of TP53 status, particularly in this set of patients frequently lacking high-risk chromosomal aberrations, emerges as a key step, not only for prediction modeling, but also for exploring mutation-specific therapeutic approaches and minimal residual disease monitoring

The dic(9;20)(p11-13;q11) is a recurrent chromosomal abnormality in patients with acute lymphoblastic leukemia. Although it results in loss of material from 9p and 20q, the molecular targets on both chromosomes have not been fully elucidated. From an initial cohort of 58 with acute lymphoblastic leukemia patients with this translocation, breakpoint mapping with fluorescence in situ hybridization on 26 of them revealed breakpoint heterogeneity of both chromosomes. PAX5 has been proposed to be the target gene on 9p, while for 20q, FISH analysis implicated the involvement of the ASXL1 gene, either by a breakpoint within (n=4) or centromeric (deletion, n=12) of the gene. Molecular copy-number counting, long-distance inverse PCR and direct sequence analysis identified six dic(9;20) breakpoint sequences. In addition to the three previously reported: PAX5-ASXL1, PAX5-C20ORF112 and PAX5-KIF3B; we identified three new ones in this study: sequences 3' of PAX5 disrupting ASXL1, and ZCCHC7 disrupted by sequences 3' of FRG1B and LOC1499503. This study provides insight into the breakpoint complexity underlying dicentric chromosomal formation in acute lymphoblastic leukemia and highlights putative target gene loci.

Although outcomes for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) are worse when treated according to adult rather than pediatric protocols, one criticism is that this may be due to the emancipation of young adults. Using case listing session of Surveillance, Epidemiology, and End Results (SEER) 18 (1973-2010), we examined outcomes for AYA with ALL defined similar to Cancer and Leukemia Group B (CALGB) 10,403 criteria (age 18-30) predicated on marital and insurance status as surrogates for emancipation (limiting analysis to 2007-2010). Analyses were conducted with SEER*Stat 8.1.2, Microsoft Excel 2007, and GraphPad Prism 6. Comparisons were made by the Fisher exact test and log rank test (Mantel-Cox); all P values were 2-sided. Although age (24 and younger vs. 25 and older) was predictive of median overall survival (OS) (not reached vs. 33; P = .0029) (3-year OS 66% vs. 49%), social factors were not. Three-year OS for insured versus uninsured patients was 61% versus 50%, and median OS was not reached versus 30 months (P = .2334). Three-year OS for single versus married patients was 62% versus 55%, with median OS not reached for both groups (P = .1084). Insurance status and marriage did not influence outcomes for AYA with ALL, suggesting that intrinsic differences in disease and disease-specific therapies are more important than social issues.

The authors report their experience with an unusual case of intracerebral sarcoma of meningeal cell origin in an 8 1/2-year-old girl. This tumor occurred 6 1/2 years after cranial irradiation at relatively low dosage (2200 rads) had been delivered to the head in the course of a multimodality treatment for acute lymphocytic leukemia. The tumor recurred approximately 10 months after the first surgical intervention. Macroscopic total excision of the recurrent growth followed by whole-brain irradiation (4500 rads) failed to eradicate it completely and local recurrence prompted reoperation 18 months later. This complication of treatment in long-term childhood leukemia survivors is briefly discussed, as well as the pathology of meningeal sarcomas

Prophylaxis of meningosis leukemia via intrathecal radioactive colloid gold injection

Energy Technology Data Exchange (ETDEWEB)

Angelov, A; Uzunov, I; Marshavelova, J [Meditsinski Fakultet, Plovdiv (Bulgaria)

1979-01-01

Prophylaxis against meningosis leukemia (ML) via intrathecal radioactive colloid gold injection was carried out for a period of three years (January 1974 - September 1976) in 21 children with acute lymphoblast leukemia (ALL). The analysis of those patients after one relatively long period of observation (28 months after the last case) reveals that ML developed as a primary isolated manifestation of a recurrence in three children, i.e. in 14.2 per cent versus 68 per cent in the control group without prophylaxis. In another child ML development is in parallel with bone marrow recurrence. The reduction of ML incidence is accompanied with a prolongation of the first remission (in 24 per cent over 2 years and 6 months) and a lengthening of survival for 50 per cent of the patients (62 per cent of the treated patients are alive two years and 4 months during the period of observation). The advantages of the prophylaxis with radioactive colloid gold is emphasized in comparison with the other prophylactic programmes.

Full Text Available Saad Sirop Kenderian, Mark R Litzow Division of Hematology, Department of Internal Medicine, Mayo Clinic, Rochester, MN, USA Abstract: Acute lymphoblastic leukemia (ALL in adolescents and young adults (AYA represents a unique and challenging disease entity. Despite the recent improvement of survival in this population over the last decade, it is still lagging behind the excellent cure rates obtained in pediatric ALL. This special population of AYA receives care from pediatric as well as adult hematologists and can be treated on pediatric or adult protocols. There is a substantial difference in disease biology, response to chemotherapy, and allogeneic stem cell transplantation between pediatric and AYA patients. This review discusses current controversies in the management of AYA, outcomes following treatment with pediatric and adult protocols, and the role of allogeneic stem cell transplantation. It focuses on the unique clinical, biological, and socioeconomic characteristics of this population that might partly explain the inferior outcomes. This review also explores recent advances in genomic profiling and emerging treatments in ALL.

To characterize the incidence, clinical features and genetics of ETV6-ABL1 leukemias, representing targetable kinase-activating lesions, we analyzed 44 new and published cases of ETV6-ABL1-positive hematologic malignancies [22 cases of acute lymphoblastic leukemia (13 children, 9 adults) and 22 myeloid malignancies (18 myeloproliferative neoplasms, 4 acute myeloid leukemias)]. The presence of the ETV6-ABL1 fusion was ascertained by cytogenetics, fluorescence in-situ hybridization, reverse transcriptase-polymerase chain reaction and RNA sequencing. Genomic and gene expression profiling was performed by single nucleotide polymorphism and expression arrays. Systematic screening of more than 4,500 cases revealed that in acute lymphoblastic leukemia ETV6-ABL1 is rare in childhood (0.17% cases) and slightly more common in adults (0.38%). There is no systematic screening of myeloproliferative neoplasms; however, the number of ETV6-ABL1-positive cases and the relative incidence of acute lymphoblastic leukemia and myeloproliferative neoplasms suggest that in adulthood ETV6-ABL1 is more common in BCR-ABL1-negative chronic myeloid leukemia-like myeloproliferations than in acute lymphoblastic leukemia. The genomic profile of ETV6-ABL1 acute lymphoblastic leukemia resembled that of BCR-ABL1 and BCR-ABL1-like cases with 80% of patients having concurrent CDKN2A/B and IKZF1 deletions. In the gene expression profiling all the ETV6-ABL1-positive samples clustered in close vicinity to BCR-ABL1 cases. All but one of the cases of ETV6-ABL1 acute lymphoblastic leukemia were classified as BCR-ABL1-like by a standardized assay. Over 60% of patients died, irrespectively of the disease or age subgroup examined. In conclusion, ETV6-ABL1 fusion occurs in both lymphoid and myeloid leukemias; the genomic profile and clinical behavior resemble BCR-ABL1-positive malignancies, including the unfavorable prognosis, particularly of acute leukemias. The poor outcome suggests that treatment with

Comparing chronic interpersonal and noninterpersonal stress domains as predictors of depression recurrence in emerging adults.

Science.gov (United States)

Sheets, Erin S; Craighead, W Edward

2014-12-01

Understanding how persistent interpersonal difficulties distinctly affect the course of major depressive disorder (MDD) during emerging adulthood is critical, given that early experiences impact future coping resources and functioning. Research on stress and MDD has mostly concentrated on stressful life events, while chronic stress largely has not been explored. The present study examined interpersonal (intimate relationship, close friendships, social life, family relationships) and noninterpersonal (academic, work, financial, personal health, and family members' health) domains of chronic stress as time-varying predictors of depressive recurrence in emerging adults. Baseline assessments identified previously depressed emerging adults (N = 119), who subsequently completed 6-month, 12-month and 18-month follow-up interviews to determine chronic stress experiences and onset of new major depressive episodes. Survival analyses indicated that time-varying total chronic stress and chronic interpersonal stress predicted higher risk for depression recurrence; however, chronic noninterpersonal stress was not associated with recurrence. Intimate relationship stress, close friendship stress, family relationship stress, personal health, and family members' health independently predicted MDD recurrence, over and above well-established depression risk factors of dysfunctional cognitions and personality disorder symptoms. Evidence that interpersonal stress could have substantial impact on course of depression is consistent with theories of emerging adulthood, a time when young people are individuating from the family and experiencing significant social transition.

The concordance rate for diagnoses of atomic bomb-related cases of leukemia in Nagasaki was determined using the French-American-British (FAB) classification for acute leukemias and myelodysplastic syndromes (MDS). Two Radiation Effects Research Foundation (RERF) hematologists and one of the members (JMB) of the FAB cooperative group reviewed independently the peripheral blood and/or bone marrow smears from 193 people with leukemia or a related disorder. There was 85 % agreement in the identification of types and subtypes of acute leukemia. There was almost complete agreement for the diagnoses of non-FAB disorders (chronic myeloid leukemia (CML), adult T-cell leukemia (ATL) and others) resulting in overall concordance of 88.2 %. The present study suggest that the previously established leukemia types for about a quarter of the cases of acute leukemia and related disorders except CML should be changed. Considerable numbers of cases of ATL and MDS were involved in this series. The frequency of the former disease was not high in the high-dose irradiated group, but that of the latter was considerably high. All subtypes of AML except M3 and M6 were present in the high-dose group. The striking difference in CML incidence between Nagasaki and Hiroshima may continue to be a problem in relation to biological response to radiation exposure.

The European Union pediatric legislation was introduced to improve pharmaceutical treatment of children, but some question whether the European Medicines Agency (EMA approach is helping children with leukemia. Some have even suggested that the decisions of EMA pediatric committee (PDCO are counterproductive. This study was designed to investigate the impact of PDCO-issued pediatric investigation plans (PIPs for leukemia drugs.Methods: All PIPs listed under “oncology” were downloaded from the EMA website. Non-leukemia decisions including misclassifications, waivers (no PIP, and solid tumors were discarded. The leukemia decisions were analyzed, compared to pediatric leukemia trials in the database http://www.clinicaltrials.gov, and discussed in the light of current literature.Results: The PDCO leukemia decisions demand clinical trials in pediatric leukemia for all new adult drugs without prioritization. However, because leukemia in children is different and much rarer than in adults, these decisions have resulted in proposed studies that are scientifically and ethically questionable. They are also unnecessary, since once promising new compounds are approved for adults, more appropriate, prioritized pediatric leukemia trials are initiated worldwide without PDCO involvement.Conclusion: EMA/PDCO leukemia PIPs do little to advance the treatment of childhood leukemia. The unintended negative effects of the flawed EMA/PDCO's standardized requesting of non-prioritized testing of every new adult leukemia drug in

Race-based survival in children and adolescents with hematologic malignancies has been a national challenge for decades. Large-scale investigations of age- and race-based survival trends over time in these patients have not previously been reported. The objective of this study was to investigate whether race- and age-related differences in pediatric and adolescent and young adult (AYA) leukemia and lymphoma survival persist and to what extent these differences have changed over time. Using the Surveillance, Epidemiology, and End Results program, this study investigated the outcomes of black and white (1975-2012; n = 27,369) and white and Hispanic (1992-2012; n = 20,574) children (0-14 years old) and AYAs (15-39 years old) with acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), and Hodgkin lymphoma (HL). Estimates of 5- and 10-year relative survival were compared over time. Trends showed a convergence of survival for white and black children with ALL but a divergence in survival for AYA patients. Hispanic children and AYAs both suffered inferior outcomes. Trends for AML revealed persistent survival differences between black and white children and suggested worsening disparities for AYAs. Survival trends in HL revealed sustained survival differences between black and white AYA patients, whereas no differences were found in Hispanic and white patient outcomes for AML or HL. Although survival for children and AYAs with ALL, AML, and HL has improved over the past 4 decades, differences persist between black, white, and Hispanic children and AYAs; survival disparities between black and white children with ALL have been nearly eliminated. Strategies aimed at identifying causality and reducing disparities are warranted. Cancer 2016. © 2016 American Cancer Society.

Chromosomal rearrangements of the human MLL (mixed lineage leukemia) gene are associated with high-risk infant, pediatric, adult and therapy-induced acute leukemias. We used long-distance inverse-polymerase chain reaction to characterize the chromosomal rearrangement of individual acute leukemia patients. We present data of the molecular characterization of 1590 MLL-rearranged biopsy samples obtained from acute leukemia patients. The precise localization of genomic breakpoints within the MLL gene and the involved translocation partner genes (TPGs) were determined and novel TPGs identified. All patients were classified according to their gender (852 females and 745 males), age at diagnosis (558 infant, 416 pediatric and 616 adult leukemia patients) and other clinical criteria. Combined data of our study and recently published data revealed a total of 121 different MLL rearrangements, of which 79 TPGs are now characterized at the molecular level. However, only seven rearrangements seem to be predominantly associated with illegitimate recombinations of the MLL gene (∼90%): AFF1/AF4, MLLT3/AF9, MLLT1/ENL, MLLT10/AF10, ELL, partial tandem duplications (MLL PTDs) and MLLT4/AF6, respectively. The MLL breakpoint distributions for all clinical relevant subtypes (gender, disease type, age at diagnosis, reciprocal, complex and therapy-induced translocations) are presented. Finally, we present the extending network of reciprocal MLL fusions deriving from complex rearrangements. PMID:23628958

None of these 5 patients responded to a chemotherapy regimen used for adult ALL. The importance of ultrastructural cytochemistry which allows the recognition of myeloblastic differentiation in undifferentiated blast cells is also demonstrated. The correct classification of such cases may be important for prognosis because they appear to be resistant to the chemotherapy used in treating ALL.

Leukemia is the first malignant disease found among A-bomb survivors. Leukemia registration has greatly contributed to epidemiological and hematological studies on A-bomb radiation-related leukemia and other hematopoietic diseases, consisting of community population and the RERF Life Span Study (LSS) sample (approximately 120,000 persons containing A-bomb survivors). Using the fixed LSS cohort, the prevalence rate of leukemia reached the peak during the years 1950-1954, and thereafter, it has been gradually decreased. However, risk patterns for leukemia are still unsolved: has leukemia risk increased in recent years?; are serial changes in leukemia risk influenced by age at the time of exposure (ATE)?; is there variation between Hiroshima and Nagasaki?; and others. To solve these questions, leukemia data are now under analysis using the revised DS86. Relative risk for leukemia, especially chronic myelogenous leukemia and acute lymphocytic leukemia (ALL), is found to be linearly increased with increasing bone marrow doses. Serial patterns of both excess risk and excess relative risk have revealed that leukemia risk is high at 5-10 years after A-bombing in younger A-bomb survivors ATE. The influence of age ATE on serial changes is noticeable in ALL. Another factor involved in the prevalence of leukemia is background (spontaneously developed leukemia), which is the recent interest because young A-bomb survivors ATE reach the cancer-prone age.

To further our understanding of the genetic basis of acute myelogenous leukemia (AML), we determined the coding exon sequences of ∼ 18 000 protein-encoding genes in 8 patients with secondary AML. Here we report the discovery of novel somatic mutations in the transcriptional corepressor gene BCORL1 that is located on the X-chromosome. Analysis of BCORL1 in an unselected cohort of 173 AML patients identified a total of 10 mutated cases (6%) with BCORL1 mutations, whereas analysis of 19 AML cell lines uncovered 4 (21%) BCORL1 mutated cell lines. The majority (87%) of the mutations in BCORL1 were predicted to inactivate the gene product as a result of nonsense mutations, splice site mutation, or out-of-frame insertions or deletions. These results indicate that BCORL1 by genetic criteria is a novel candidate tumor suppressor gene, joining the growing list of genes recurrently mutated in AML.

To investigate the risk factors of recurrence of pneumothorax following thoracoscopic bullectomy in young adults. Between January, 2005 and September, 2015, 167 patients aged ≤40 years underwent initial thoracoscopic bullectomy for primary spontaneous pneumothorax (PSP) at our hospital. Recurrence-free probability was calculated from the date of surgery to recurrence or last follow-up, using the Kaplan-Meier method. Sixteen (9.6%) of the 167 patients suffered a recurrence (collective total, 16 recurrences). The recurrence-free intervals were 3-107 months (median 25.8 months), and the 5-year recurrence-free probability was 85.9%. Multivariate Cox analysis demonstrated that age ≤23 years (p = 0.029) and a history of ipsilateral pneumothorax before surgery (p = 0.029) were significantly associated with higher risk of recurrence. The 5-year recurrence-free probability was 72.3% for patients aged ≤23 years and a history of ipsilateral pneumothorax before surgery and 94.1% for those with neither of these factors (p = 0.001). Recurrence developed within 3 years after surgery in 14 of the 16 patients. Patients ≤23 years of age with a history of ipsilateral pneumothorax before surgery are at significantly high risk of its recurrence, frequently within 3 years; thus, the risk of postoperative recurrence of a pneumothorax must be kept in mind.

After the Chernobyl accident the whole population of Poland was exposed to low-level radiation mainly emitted by I-131 and Cs-137. In 6-year period the incidence of leukemia increased in 2 groups of children: age 0-4 in males and 5-7 in females. In adults in some clinical types of leukemia significant trends of incidence were observed: in acute myleoid leukemia in age groups of 70-79 for males, in chronic myleoid leukemia in age groups of 40-49 and 60-69 for females, in chronic lymphatic leukemia in age group of 70-79 for males. Non of those trends was significant prior to the Chernobyl disaster

The prevalence of the metabolic syndrome among adults from the French LEA childhood acute leukemia survivors’ cohort was prospectively evaluated considering the type of anti-leukemic treatment received, and compared with that of controls. The metabolic profile of these patients was compared with that of controls. A total of 3203 patients from a French volunteer cohort were age- and sex-matched 3:1 to 1025 leukemia survivors (in both cohorts, mean age: 24.4 years; females: 51%). Metabolic syndrome was defined according to the National Cholesterol Education Program’s Adult Treatment Panel III criteria. Metabolic syndrome was found in 10.3% of patients (mean follow-up duration: 16.3±0.2 years) and 4.5% of controls, (OR=2.49; Pmetabolic syndrome displayed a unique profile compared with controls: smaller waist circumference (91 vs. 99.6 cm; P=0.01), and increased triglyceride levels (3.99 vs. 1.5 mmol/L; Pmetabolic syndrome had a larger waist circumference (109 vs. 99.6 cm; P=0.007) than controls. Regardless of the anti-leukemic treatment, metabolic syndrome risk was higher among childhood leukemia survivors. Its presentation differed depending on the treatment type, thus suggesting a divergent pathophysiology. This study is registered at clinicaltrials.gov identifier: 01756599. PMID:29351982

The latest studies suggest that prophylactic chemotherapy or adjuvant chemotherapy for early stage breast cancer may increase the leukemia risk in patients. For patients with a low risk for breast cancer recurrence, physicians who make the choice for adjuvant therapy should consider the risk of its long-term side effects. Is the occurrence of lymphatic system cancer and leukemia after breast cancer treatment associated with chemotherapy? Can these types of leukemia be classified as therapy-related leukaemias? We believe that there may be correlations between any diseases, butwe cannot rush to conclusions or dismiss a correlation because we understand little about the diseases themselves.In this paper, we present a case of secondary diffuse large B-cell lymphoma and leukemia in patients after breast cancer chemotherapy, it is undeniable that this is a special event. For two distinct tumouroccurrences at different times, we cannot give a clear explanation because of thechanges in the genes that might link them together and we hope to attract the attention of other clinicians.

A marked increase in leukemia risks was the first and most striking late effect of radiation exposure seen among the Hiroshima and Nagasaki atomic bomb survivors. This paper presents analyses of radiation effects on leukemia, lymphoma, and multiple myeloma incidence in the Life Span Study cohort of atomic bomb survivors updated 14 years since the last comprehensive report on these malignancies. These analyses make use of tumor- and leukemia-registry-based incidence data on 113,011 cohort members with 3.6 million person-years of follow-up from late 1950 through the end of 2001. In addition to a detailed analysis of the excess risk for all leukemias other than chronic lymphocytic leukemia or adult T-cell leukemia (neither of which appear to be radiation-related), we present results for the major hematopoietic malignancy types: acute lymphoblastic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, chronic myeloid leukemia, adult T-cell leukemia, Hodgkin and non-Hodgkin lymphoma, and multiple myeloma. Poisson regression methods were used to characterize the shape of the radiation dose response relationship and, to the extent the data allowed, to investigate variation in the excess risks with sex, attained age, exposure age, and time since exposure. In contrast to the previous report that focused on describing excess absolute rates, we considered both excess absolute rate (EAR) and excess relative risk (ERR) models and found that ERR models can often provide equivalent and sometimes more parsimonious descriptions of the excess risk than EAR models. The leukemia results indicated that there was a non-linear dose response for leukemias other than chronic lymphocytic leukemia or adult T-cell leukemia, which varied markedly with time and age at exposure, with much of the evidence for this non-linearity arising from the acute myeloid leukemia risks. Although the leukemia excess risks generally declined with attained age or time since exposure, there was evidence

Abstract To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis. We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition. Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002–1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063–0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338–1.934, P = .663). Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome

Stroke in young adults is uncommon and rarely described. Moyamoya disease is one of the leading causes of stroke in young adults. We aimed to study the prognostic factors for stroke recurrences and functional outcomes in young stroke patients with moyamoya disease after revascularization. We reviewed 696 consecutive patients with moyamoya disease admitted to our hospital from 2009-2015 and identified patients aged 18-45 years with first-ever stroke. Follow-up was conducted via face-to-face or structured telephone interviews. Outcome measures were recurrent stroke events and unfavorable functional outcomes (modified Rankin Scale >2). We included 121 young patients with moyamoya disease suffering from stroke (initial presentation age, 35.4 ± 7.5 years). All patients underwent revascularization after the acute phase of initial stroke events as the secondary prevention for recurrences. During follow-up (median, 40 months), 9 patients (7.4%) experienced recurrent strokes and 8 of them (6.6%) suffered unfavorable functional outcomes. In the multivariate analysis, diabetes was an independent predictor for stroke recurrences (hazard ratio 6.76; 95% confidence interval 1.30-35.11; P = 0.02) and was significantly associated with unfavorable functional outcomes (odds ratio 7.87; 95% confidence interval 1.42-38.74; P = 0.01). We identified diabetes as an independent risk factor for recurrent strokes and unfavorable functional outcomes after revascularization in young stroke patients with moyamoya disease.

Full Text Available Yvonne Kiefer1, Christoph Schulte2, Markus Tiemann2, Joern Bullerdiek11Center for Human Genetics, University of Bremen, Bremen, Germany; 2Hematopathology Hamburg, Hamburg, GermanyAbstract: Chronic lymphocytic leukemia is the most common leukemia in adults. By cytogenetic investigations major subgroups of the disease can be identified that reflect different routes of tumor development. Of these chromosomal deviations, trisomy 12 and deletions of parts of either the long arm of chromosome 13, the long arm of chromosome 11, or the short arm of chromosome 17 are most commonly detected. In some of these aberrations the molecular target has been identified as eg, ataxia telangiectasia mutated (ATM in case of deletions of chromosomal region 11q22~23 and the genes encoding microRNAs miR-15a/16-1 as likely targets of deletions of chromosomal band 13q14.3. Of note, these aberrations do not characterize independent subgroups but often coexist within the metaphases of one tumor. Generally, complex aberrations are associated with a worse prognosis than simple karyotypic alterations. Due to smaller sizes of the missing segment the detection of recurrent deletions is not always possible by means of classical cytogenetics but requires more advanced techniques as in particular fluorescence in situ hybridization (FISH. Nevertheless, at this time it is not recommended to replace classical cytogenetics by FISH because this would miss additional information given by complex or secondary karyotypic alterations. However, the results of cytogenetic analyses allow the stratification of prognostic and predictive groups of the disease. Of these, the group characterized by deletions involving TP53 is clinically most relevant. In the future refined methods as eg, array-based comparative genomic hybridization will supplement the existing techniques to characterize CLL.

Tumor immune escape mechanism mediated by CD4+CD25+regulatory T cells (Tregs) is a key factor in the pathogenesis of acute myeloid leukemia (AML). IL-35, as a novel inhibitory cytokine, is produced by Tregs specially and regulates functions of Tregs in murine. However, IL-35 expression of Tregs in human is still disputed, and its role in AML is yet to be elucidated. In this study, we found that IL-35 was expressed highly in peripheral blood plasma of adult patients with AML and significantly correlated with the clinical stages of malignancy. Tregs-derived from adult AML patients produced IL-35 in a stimulation-dependent manner. IL-35 promoted AML blasts immune escape by expanding Tregs and inhibiting CD4+CD25-effector T cells (Teffs). Furthermore, IL-35 directly promoted the proliferation of AML blasts and reduced the apoptosis of AML blasts. Together, our study demonstrates that IL-35-derived from Tregs promotes the growth of adult AML blasts, suggesting that IL-35 has an important role in the pathogenesis of AML. © 2015 UICC.

IgA vasculitis, a rare condition resulting in end-stage renal disease, is a small-vessel vasculitis that affects the kidney in 49-83 % of adults. The reported recurrence rate of IgA vasculitis in renal transplant recipients is 11.5-60 %, leading to graft loss in 0-50 % of these patients. However, limited data are available on recurrence and graft loss after renal transplantation. We evaluated renal transplant recipients seen from 1987 to 2015 at the Jikei University School of Medicine and the Department of Urology, Tokyo Women's Medical University. Using a 1:2 match, 21 patients with IgA vasculitis and 42 controls were selected. The mean post-transplant follow-up was 121 ± 69 months for IgA vasculitis and 147 ± 66 months for the controls. The 15-year patient survival was 100 % in IgA vasculitis and 97.6 % in the controls (p = 0.22). The 5-, 10-, and 15-year graft survival rates were 95.2, 90.5, and 81 % in IgA vasculitis and 100, 90.5, and 88.1 % in the controls, respectively (p = 0.63). The recurrence rate was 28.6 % (6 of 21 cases) and half of them (3 of 6 cases) showed histological activity (ISKDC III). We treated them with methylprednisolone pulse therapy and/or tonsillectomy. None of the recurrence cases lost the allograft. The long-term patient and graft survival of IgA vasculitis in renal transplantation were comparable with the previous reports. The recurrence rate was 28.6 %, but none of the recurrent cases showed allograft loss in this study. We speculate that methylprednisolone pulse therapy and/or tonsillectomy prevent the progression of recurrent IgA vasculitis.

Full Text Available Objective: To evaluate trends in mortality among adults with myeloid leukemia in the Vale do Paraíba, State of São Paulo. Methods: Data from the Brazilian National Health Service database DATASUS provided the number of deaths caused by myeloid leukemia and the number of inhabitants per year in the Regional Health Division XVII from 1994 to 2011. Registries were categorized according to gender into four age ranges (over 20 years, 20-49, 50-69 and over 70 years for an estimation of the annual percent change for age-adjusted mortality rates. The percent changes were calculated using the Joinpoint regression analysis model. Results: Overall, a significant decline per year was demonstrated for the entire sample (over 20 years across the 18-year period studied (annual percent change: −5.59%; 95% CI: −8.5 to −2.5% for males; p-value < 0.05 and −7.02%; 95% CI −11.2 to −2.8% for females; p-value < 0.05 with no significant difference between genders. In an analysis using two Joinpoints, significant drops were observed from 1994 to 2001 (annual percent change: −21.22%; 95% confidence interval: −27.9 to −13.9%; p-value < 0.05 and from 1994 to 2003 (annual percent change: −12.86%; 95% confidence interval −22.2 to −2.5%; p-value < 0.05 for men and women, respectively. The declining trends were greatest for patients aged over 70 years with the age-adjusted mortality rates in younger groups declining non-significantly except for males aged 50-69 years old. Conclusion: Our data suggest a significant decline per year in age-adjusted mortality rates of adult patients diagnosed with myeloid leukemia from 1994 to 2011 in the Vale do Paraíba, State of São Paulo.

Allogeneic hematopoietic SCT (allo-SCT) is a promising therapy that may provide long-term durable remission for adult T-cell leukemia-lymphoma (ATL) patients; however, the incidence of relapse associated with ATL remains high. To determine the clinical features of these patients at relapse, we retrospectively analyzed tumor lesions in 30 or 49 patients who relapsed following allo-SCT or chemotherapy (CHT), respectively, at three institutions in Nagasaki prefecture between 1997 and 2011. A multivariate analysis revealed that the development of abnormal lymphocytes in the peripheral blood of patients at relapse was less frequent after allo-SCT than after CHT (PSCT (P=0.014). Lesions were more frequently observed in the central nervous systems of patients who relapsed with new lesions only (P=0.005). Thus, the clinical manifestation of relapsed ATL was slightly complex, especially in post-transplant patients. Our results emphasized the need to develop adoptive modalities for early and accurate diagnoses of relapsed ATL.

Full Text Available Robo4 is involved in hematopoietic stem/progenitor cell homeostasis and essential for tumor angiogenesis. Expression of Robo4 was recently found in solid tumors and leukemia stem cells. However, the clinical implications of Robo4 expression in patients with acute myeloid leukemia (AML remain unclear.We investigated the clinical and prognostic relevance of mRNA expression of Robo4 in bone marrow (BM mononuclear cells from 218 adult patients with de novo AML. We also performed immunohistochemical staining to assess the Robo4 protein expression in the BM biopsy specimens from 30 selected AML patients in the cohort.Higher Robo4 expression was closely associated with lower white blood cell counts, expression of HLA-DR, CD13, CD34 and CD56 on leukemia cells, t(8;21 and ASXL1 mutation, but negatively correlated with t(15;17 and CEBPA mutation. Compared to patients with lower Robo4 expression, those with higher expression had significantly shorter disease-free survival (DFS and overall survival (OS. This result was confirmed in an independent validation cohort. Furthermore, multivariate analyses showed that higher Robo4 expression was an independent poor prognostic factor for DFS and OS in total cohort and patients with intermediate-risk cytogenetics, irrespective of age, WBC count, karyotype, and mutation status of NPM1/FLT3-ITD, and CEBPA.BM Robo4 expression can serve as a new biomarker to predict clinical outcomes in AML patients and Robo4 may serve as a potential therapeutic target in patients with higher Robo4 expression.

Full Text Available Abstract Background Adult T-cell leukemia/lymphoma (ATLL is a malignancy derived from T cells infected with human T-cell leukemia virus type 1 (HTLV-1, and it is known to be resistant to standard anticancer therapies. Indole-3-carbinol (I3C, a naturally occurring component of Brassica vegetables such as cabbage, broccoli and Brussels sprout, is a promising chemopreventive agent as it is reported to possess antimutagenic, antitumorigenic and antiestrogenic properties in experimental studies. The aim of this study was to determine the potential anti-ATLL effects of I3C both in vitro and in vivo. Results In the in vitro study, I3C inhibited cell viability of HTLV-1-infected T-cell lines and ATLL cells in a dose-dependent manner. Importantly, I3C did not exert any inhibitory effect on uninfected T-cell lines and normal peripheral blood mononuclear cells. I3C prevented the G1/S transition by reducing the expression of cyclin D1, cyclin D2, Cdk4 and Cdk6, and induced apoptosis by reducing the expression of XIAP, survivin and Bcl-2, and by upregulating the expression of Bak. The induced apoptosis was associated with activation of caspase-3, -8 and -9, and poly(ADP-ribose polymerase cleavage. I3C also suppressed IκBα phosphorylation and JunD expression, resulting in inactivation of NF-κB and AP-1. Inoculation of HTLV-1-infected T cells in mice with severe combined immunodeficiency resulted in tumor growth. The latter was inhibited by treatment with I3C (50 mg/kg/day orally, but not the vehicle control. Conclusion Our preclinical data suggest that I3C could be potentially a useful chemotherapeutic agent for patients with ATLL.

Full Text Available Abstract Background We highlight the orbital manifestations of acute myeloid leukemia and the role of peripheral blood smear in the diagnosis of these cases. A total of 12 patients who presented with proptosis and were subsequently diagnosed to have acute myeloid leukemia based on incision biopsy or peripheral blood smear were included in the study. Results A retrospective review of all cases of acute myeloid leukemia presenting to the Orbital clinic was performed. The age at presentation, gender, presenting features, duration of symptoms and fundus features were noted. In addition the temporal relationship of the orbital disease to the diagnosis of leukemia, laterality, location of the orbital mass, imaging features and the diagnostic tools used to diagnose leukemia were noted. The median age at presentation was 6 years. The male: female ratio was 0.7:1. None of these patients had been diagnosed earlier as having acute myeloid leukemia. The presenting features included proptosis in all patients, orbital mass in 5 (41.7%, visual symptoms in 2 (16.7% and subconjunctival hemorrhage in one patient (8.3%. A diagnosis of acute myeloid leukemia was established by incision biopsy in 4 patients, subsequently confirmed by peripheral blood smear testing and bone marrow biopsy in 2 patients which revealed the presence of systemic involvement. Imprint smears of the biopsy identified blasts in 2 of 4 cases. In 8 patients presenting with ocular manifestations, diagnosis was established by peripheral blood smear examination alone which revealed a diagnosis of acute myeloid leukemia. Conclusion A peripheral blood smear should be performed in all cases of sudden onset proptosis or an orbital mass in children and young adults along with an orbital biopsy. It can always be complemented with a bone marrow biopsy especially in cases of aleukemic leukemia or when the blood smear is inconclusive.

2005-01-01

Vascular access-related complications are a frequent cause of morbidity in haemodialysis patients and generate high costs. We present the case of an adult patient with end-stage renal disease and recurrent vascular access thrombosis associated with the prothrombin mutation G20210A and renal graft intolerance. The clinical expression of this heterozygous gene mutation may have been favoured by inflammatory state, frequent in dialysis patients. In this patient, the inflammatory response associated with the renal graft intolerance would have favored the development of recurrent vascular access thrombosis in a adult heterozygous for prothrombin mutation G20210A. In the case of early dysfunction of haemodialysis vascular access and after ruling out technical problems, it is convenient to carry out a screening for thrombophilia.

Unrelated allogeneic stem-cell transplantation in adult patients – 10-year experience

Conclusion: Unrelated allogeneic stem-cell transplantation is suitable for acute myeloblastic leukemias with unfavorable risk factors. However, results in acute lymphoblastic leukemia are worse. Unrelated transplantation is not efficient as salvage treatment for patients with recurrent disease after autologous transplantation or chemotherapy- resistant relapse.

Objective: To explore the clinical significance of changes in serum IGF-II, TNF-α and TSGF levels after chemotherapy in patients with acute leukemia. Methods: Serum IGF-II, TNF-α (with RIA) and TSGF (with biochemistry) levels were determined in 33 patients with acute leukemia both before and after chemotherapy as well as in 35 normal healthy Controls. Results: Before chemotherapy, serum IGF-II, TNF-α and TSGF levels in the patients were significantly higher than those in controls (P<0.01), 6 months after chemotherapy the levels in 28 patients without recurrence dropped markedly and approached those in controls. However, in the 5 eases with recurrence, the levels after return again, approaching those before chemotherapy. Conclusion: Changes of serum levels on IGF-II, TNF-α and TSGF might be useful as indicative parameters for diagnosis and curative effect in patients with acute leukemia. (authors)

The Meaning of Disease and Spiritual Responses to Stressors in Adults With Acute Leukemia Undergoing Hematopoietic Stem Cell Transplantation.

Science.gov (United States)

Farsi, Zahra

2015-12-01

Some studies have shown that patients with cancer may experience significant spiritual distress as well as spiritual growth, that there is a positive association between spirituality and coping, and that positive religious coping predicts enhanced health outcomes. This study was designed to help explain how the meaning of disease and spiritual responses to threatening stressors influence the final experiential outcomes of adults with leukemia undergoing hematopoietic stem cell transplantation in Iran. This grounded theory study conducted in-depth interviews between 2009 and 2011 on 10 adults in Iran with leukemia undergoing hematopoietic stem cell transplantation. Recorded audio interviews were transcribed verbatim in Persian and coded and analyzed using Corbin and Strauss (2008)'s approach. Main categories that emerged from data included "experiencing the meaning of cancer"; "changing perceptions of death, life and health"; and "moving toward perfection and sublimity." "Finding meaning" was the main concept that defined the final outcome of the experience of participants. Understanding the meaning to patients of disease and treatments may help healthcare providers better appreciate the patients' perspective and improve the physician-patient relationship. Nurses are well positioned to play a decisive role in helping patients cope effectively with their treatment process and in helping ensure positive outcomes for treatments through their helping patients find the unique meaning of their experience.

Monocytic leukemias.

The monocytic leukemias may be subdivided into acute monocytic leukemia, acute myelomonocytic leukemia, and subacute and chronic myelomonocytic leukemia. The clinical features of acute monocytic and acute myelomonocytic leukemias are similar and are manifestations of bone marrow failure. Gingival hypertrophy and skin infiltration are more frequent in acute monocytic leukemia. Cytomorphologically the blast cells in acute monocytic leukemia may be undifferentiated or differentiated, whereas in the acute myelomonocytic variety there are mixed populations of monocytic and myeloblastic cells. Cytochemical characteristics include strongly positive reactions for nonspecific esterase, inhibited by fluoride. The functional characteristics of acute monocytic and acute myelomonocytic cells resemble those of monocytes and include glass adherence and phagocytoses, the presence of Fc receptors for IgG and C'3, and the production of colony stimulating activity. Subacute and chronic myelomonocytic leukemias are insidious and slowly progressive diseases characterized by anemia and peripheral blood monocytosis. Atypical monocytes called paramyeloid cells are characteristic. The drugs used in the treatment of acute monocytic and acute myelomonocytic leukemias include cytosine arabinoside, the anthracyclines, and VP 16-213. Drug therapy in subacute and chronic myelomonocytic leukemias is not usually indicated, although VP 16-213 has been claimed to be effective.

Proliferation kinetics and cyclic AMP as prognostic factors in adult acute leukemia.

Science.gov (United States)

Paietta, E; Mittermayer, K; Schwarzmeier, J

1980-07-01

In 41 adult patients with acute leukemia (myeloblastic, lymphoblastic, and undifferentiated), proliferation kinetics (as determined by double-label autoradiography) and cyclic adenosine 3',5'-monophosphate (cAMP) concentration were studied for their significance in the prediction of responsiveness to cytostatic therapy. Patients with good clinical response had significantly shorter turnover times and higher labeling indices in the bone marrow than did those who failed to respond to treatment. Cases for which cell kinetics did not correlate with clinical response were explained by variance in the distribution of leukemic blasts between the proliferative cell cycle and the resting pool. Good clinical response was also found to be associated with low levels of cAMP in leukemic cells prior to therapy, whereas high cAMP contents predicted failure. Low cAMP concentrations, however, did not necessarily correlate with short turnover times and vice versa. This might be due to fluctuations of the cAMP concentrations during the cell cycle.

In B-cell acute lymphoblastic leukemia (B-ALL) separation of normal hematopoietic stem cells (HSC) has so far been limited to a subgroup of patients. As aldehyde dehydrogenase (ALDH)-activity is enriched in various stem cells we investigated its value for HSC isolation in adult B-ALL. Based on ALDH-activity patients could be stratified in ALDH-numerous (≥1.9% ALDH +  cells) and ALDH-rare (cells) cases. In ALDH-rare B-ALL clonal-marker negative HSC could be separated by the CD34 + CD38 - ALDH +  phenotype, whereas this separation was not possible in ALDH-numerous B-ALL. Functional analysis confirmed the HSC-potential of isolated cells, which were uniformly CD19-negative. However, addition of ALDH-activity further improved HSC-purity. In summary, we provide a method to separate functionally normal HSC from leukemic cells in a subgroup of B-ALL patients that can be identified prospectively. This protocol thereby facilitates comparative analyses of matched HSC and leukemic cells in order to improve our understanding of leukemia evolution.

The superiority of the pediatric protocol for adolescents with acute lymphoblastic leukemia (ALL) has already been demonstrated, however, its efficacy in young adults remains unclear. The ALL202-U protocol was conducted to examine the efficacy and feasibility of a pediatric protocol in adolescents and young adults (AYAs) with BCR–ABL-negative ALL. Patients aged 15–24 years (n=139) were treated with the same protocol used for pediatric B-ALL. The primary objective of this study was to assess the disease-free survival (DFS) rate and its secondary aims were to assess toxicity, the complete remission (CR) rate and the overall survival (OS) rate. The CR rate was 94%. The 5-year DFS and OS rates were 67% (95% confidence interval (CI) 58–75%) and 73% (95% CI 64–80%), respectively. Severe adverse events were observed at a frequency that was similar to or lower than that in children treated with the same protocol. Only insufficient maintenance therapy significantly worsened the DFS (hazard ratio 5.60, P<0.001). These results indicate that this protocol may be a feasible and highly effective treatment for AYA with BCR–ABL-negative ALL

Antiangiogenic Therapy in the Treatment of Recurrent Medulloblastoma in the Adult: Case Report and Review of the Literature

Directory of Open Access Journals (Sweden)

Giuseppe Privitera

2009-01-01

Full Text Available Medulloblastoma is a rare tumor in central nervous system, with an even rarer occurrence in adulthood. The management of a recurrent disease is a medical challenge; chemotherapy has been used as the treatment of choice, while reirradiation has been employed in selected cases. We report the case of a 51-year-old man with recurrent medulloblastoma. He was treated with local reirradiation, chemotherapy, and antiangiogenic drug, with the latter giving the longer progression-free interval. The aim of this report is to show that recurrent medulloblastoma in adults can be approached with a multimodality treatment and that antiangiogenic therapy should have a role in the management of this disease.

Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

Objective: To document the clinical presentation and epidemiology of various types of acute leukemia with their respective referral source at a tertiary level centre in Peshawar. Study Design: An observational study. Place and Duration of Study: Department of Pathology, Hayatabad Medical Complex (HMC), Peshawar, from January 2011 to May 2012. Methodology: A total of 618 bone marrow biopsy reports were reviewed. All biopsy reports labeled as acute leukemia were reviewed for age, gender, address, referring unit, diagnosis on bone marrow examination, presenting complaints, duration of illness and findings of clinical examination. Results: Ninety-two patients were diagnosed as suffering from acute leukemias (15%). ALL was most prevalent (46%), followed by AML (38%) and undifferentiated acute leukemia (16%). Males were affected more compared to females (60% vs. 40%). ALL and AML were predominant in pediatric (64%) and adults (77%) patients respectively. Patients from Afghanistan accounted for 33% of all cases followed by Peshawar (14%). Fever (77%), pallor (33%) and bleeding disorders (23%) were the main presenting complaints. Enlargement of liver, spleen and lymph nodes together was associated with ALL compared with AML (p = 0.004). Conclusion: ALL-L1 and AML-M4 were the most common sub-types. Fever, pallor and bleeding disorders were the main presenting complaints. Enlargement of liver, spleen and lymph nodes was more frequently associated with ALL compared to AML. (author)

NF-κB signaling mechanisms in HTLV-1-induced adult T-cell leukemia/lymphoma.

Science.gov (United States)

Harhaj, Edward William; Giam, Chou-Zen

2018-05-03

The human T-cell leukemia virus type 1 (HTLV-1) is a complex deltaretrovirus linked to adult T-cell leukemia/lymphoma (ATLL), a fatal CD4+ malignancy in 3-5% of infected individuals. The HTLV-1 Tax regulatory protein plays indispensable roles in regulating viral gene expression and activating cellular signaling pathways that drive the proliferation and clonal expansion of T cells bearing HTLV-1 proviral integrations. Tax is a potent activator of NF-κB, a key signaling pathway that is essential for the survival and proliferation of HTLV-1 infected T cells. However, constitutive NF-κB activation by Tax also triggers a senescence response, suggesting the possibility that only T cells capable of overcoming NF-κB-induced senescence can selectively undergo clonal expansion after HTLV-1 infection. Tax expression is often silenced in the majority of ATLL due to genetic alterations in the tax gene or DNA hypermethylation of the 5'-LTR. Despite the loss of Tax, NF-κB activation remains persistently activated in ATLL due to somatic mutations in genes in the T/B-cell receptor (T/BCR) and NF-κB signaling pathways. In this review, we focus on the key events driving Tax-dependent and independent mechanisms of NF-κB activation during the multi-step process leading to ATLL. This article is protected by copyright.

According to the current knowledge of diagnosis and classification, a review of 157 patients who had developed leukemia before June 30, 1967 was made. The incidence of acute leukemia decreased slightly among A-bomb survivors in Hiroshima; however, the incidence of acute lymphatic leukemia (ALL) increased. The number of chronic myeloid leukemia (CML) was unchanged. The frequency of CML implied that A-bombing damaged stem cells. Among A-bomb survivors in Nagasaki, although the number of acute non-lymphatic leukemia decreased, the number of ALL was unchanged. Adult T-cell leukemia (ATL) was diagnosed in 7 A-bomb survivors, confirming that Nagasaki is an endemic area for ATL. These preliminary results seem to be of importance in elucidating the mechanism of leukemia developing among A-bomb survivors. (Namekawa, K.).

Adult T cell leukemia (ATL) is caused by the human T cell leukemia virus type I (HTLV-I). Although the mechanisms of the leukemogenic process are unknown, the tax gene may have a role in this process. Because clustering occurs with HTLV-I and ATL, members of ATL families were examined for antibodies to the tax protein and compared with matched HTLV-I-positive blood donors. To investigate the antibody response to this protein, a plasmid, pBHX-4, was constructed to express a recombinant tax protein (r-tax). For ATL patients and their HTLV-I antibody-positive blood relatives, the rate of seroreactivity with the r-tax protein was 67.3% (35/52), compared with 51.6% (97/188) for HTLV-I antibody-positive control blood donors (P less than .05). The difference between direct offspring of ATL patients and matched HTLV-I blood donors was even greater (84.2% [16/91] vs. 44.2% [42/95]; P less than .005). Thus, tax antibody positivity in direct offspring of ATL patients may reflect differences in time or route of HTLV-I infection. Alternatively, it might reflect genetic differences in host susceptibility or virus strain.

Molecular biomarkers for the study of childhood leukemia

Various specific chromosome rearrangements, including t(8;21), t(15;17), and inv(16), are found in acute myeloid leukemia (AML) and in childhood acute lymphocytic leukemia (ALL), t(12;21) and t(1;19) are common. We sequenced the translocation breakpoints of 56 patients with childhood ALL or AML harboring t(12;21), t(8;21), t(15;17), inv(16), and t(1;19), and demonstrated, with the notable exception of t(1;19), that these rearrangements are commonly detected in the neonatal blood spots (Guthrie cards) of the cases. These findings show that most childhood leukemias begin before birth and that maternal and perinatal exposures such as chemical and infectious agents are likely to be critical. Indeed, we have reported that exposure to indoor pesticides during pregnancy and the first year of life raises leukemia risk, but that later exposures do not. We have also examined aberrant gene methylation in different cytogenetic subgroups and have found striking differences between them, suggesting that epigenetic events are also important in the development of some forms of childhood leukemia. Further, at least two studies now show that the inactivating NAD(P)H:quinone acceptor oxidoreductase (NQO1) C609T polymorphism is positively associated with leukemias arising in the first 1-2 years of life and polymorphisms in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene have been associated with adult and childhood ALL. Thus, low folate intake and compounds that are detoxified by NQO1 may be important in elevating leukemia risk in children. Finally, we are exploring the use of proteomics to subclassify leukemia, because cytogenetic analysis is costly and time-consuming. Several proteins have been identified that may serve as useful biomarkers for rapidly identifying different forms of childhood leukemia

[Identification of novel pathogenic gene mutations in pediatric acute myeloid leukemia by whole-exome resequencing].

Shiba, Norio

2015-12-01

A new class of gene mutations, identified in the pathogenesis of adult acute myeloid leukemia (AML), includes DNMT3A, IDH1/2, TET2 and EZH2. However, these mutations are rare in pediatric AML cases, indicating that pathogeneses differ between adult and pediatric forms of AML. Meanwhile, the recent development of massively parallel sequencing technologies has provided a new opportunity to discover genetic changes across entire genomes or proteincoding sequences. In order to reveal a complete registry of gene mutations, we performed whole exome resequencing of paired tumor-normal specimens from 19 pediatric AML cases using Illumina HiSeq 2000. In total, 80 somatic mutations or 4.2 mutations per sample were identified. Many of the recurrent mutations identified in this study involved previously reported targets in AML, such as FLT3, CEBPA, KIT, CBL, NRAS, WT1 and EZH2. On the other hand, several genes were newly identified in the current study, including BCORL1 and major cohesin components such as SMC3 and RAD21. Whole exome resequencing revealed a complex array of gene mutations in pediatric AML genomes. Our results indicate that a subset of pediatric AML represents a discrete entity that could be discriminated from its adult counterpart, in terms of the spectrum of gene mutations.

To the best of our knowledge, few studies have evaluated the nutritional status in patients with acute myeloid leukemia (AML) during induction treatment. The aim of this retrospective study was to describe nutritional status of newly diagnosed adult patients with AML at admission and during induction chemotherapy. We included consecutive newly diagnosed adult patients with AML who were admitted to the Department of Hematology (Limoges University Hospital) from April 2010 to January 2014. Nutritional assessment included body mass index (BMI) and weight loss to diagnose undernutrition. Weekly laboratory tests were collected and total energy expenditure was calculated to adapt food intake. Of 95 patients, 14 (15%) presented with undernutrition at admission: low BMI values (P 5% for 9.5% patients. After chemotherapy induction, 17 patients (18%) were undernutrition (P = 0.05). Patients without undernutrition had a significantly lower median weight, BMI, and serum albumin level at discharge compared with their admission values (P nutritional status undergoing induction chemotherapy have shorter hospital stays and longer survival.

2012-06-01

A substantial number of patients with major depressive disorder (MDD) do not respond to treatment, and recurrence rates remain high. The purpose of this study was to examine a history of severe childhood abuse as a moderator of response following a 16-week acute treatment trial, and of recurrence over a 12-month follow-up. Participants included 203 adult outpatients with MDD (129 women; age 18-60). The design was a 16-week single-center randomized, open label trial of interpersonal psychotherapy, cognitive-behavioral therapy, or antidepressant medication, with a 12-month naturalistic follow-up, conducted at a university psychiatry center in Canada. The main outcome measure was Hamilton Depression Rating Scale scores at treatment end point. Childhood maltreatment was assessed at the completion of treatment using an interview-based contextual measure of childhood physical, sexual, and emotional abuse. Multiple imputation was adopted to estimate missing values. Patients with severe maltreatment were significantly less likely to respond to interpersonal psychotherapy than to cognitive-behavioral therapy or medication (OR = 3.61), whereas no differences among treatments were found in those with no history of maltreatment (ORs therapy than from interpersonal psychotherapy. However, these patients remain vulnerable to recurrence regardless of treatment modality.

Evidence-based guidelines for the use of tyrosine kinase inhibitors in adults with Philadelphia chromosome–positive or BCR-ABL–positive acute lymphoblastic leukemia: a Canadian consensus

Adult Philadelphia chromosome–positive (Ph+) or BCR-ABL–positive (BCR-ABL+) acute lymphoblastic leukemia (all) is an acute leukemia previously associated with a high relapse rate, short disease-free survival, and poor overall survival. In adults, allogeneic hematopoietic cell transplant in first remission remains the only proven curative strategy for transplant-eligible patients. The introduction of tyrosine kinase inhibitors (tkis) in the treatment of patients with Ph+ or BCR-ABL+ all has significantly improved the depth and duration of complete remission, allowing more patients to proceed to transplantation. Although tkis are now considered a standard of care in this setting, few randomized trials have examined the optimal use of tkis in patients with Ph+ all. Questions of major importance remain, including the best way to administer these medications, the choice of tki to administer, and the schedule and the duration to use. We present the results of a systematic review of the literature with consensus recommendations based on the available evidence. PMID:24764712

We report a case of primitive neuroectodermal tumor (PNET) arising 8 years after chemotherapy and radiotherapy for acute lymphoblastic leukemia. A 15-year-old boy with a history of acute lymphoblastic leukemia, at the age of 7, underwent chemotherapy and 14 Gy of radiotherapy to the whole brain. He was admitted to our department due to the development of aphasia, right hemiparesis and generalized convulsive seizure. MRI showed an irregularly enhanced mass in the left frontal lobe. A gross total removal of the tumor was performed and histological examination showed it to be PNET. Postoperatively, the patient underwent 20 Gy of radiotherapy to the whole brain and 42 Gy of local radiotherapy. Follow-up MRI showed no evidence of recurrent tumor 4 months after the radiotherapy. This tumor was thought to be a secondary brain tumor arising in this survivor of childhood acute lymphoblastic leukemia and it is a rare complication of successful leukemia treatment. (author)

There is limited amount of data available on the comparative efficacy of ibrutinib and idelalisib, the B-cell receptor inhibitors (BCRi) newly approved for relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (r/r CLL/SLL) treatment. The aim of our study was to analyze and compare the outcomes of real-world r/r CLL/SLL patients treated with these two BCRi in outside clinical trials. A comparative case matched 1:2 analysis was performed on idelalisib combined with rituximab and ibrutinib efficacy in 102 patients with r/r CLL/SLL from two observational studies of the Polish Adult Leukemia Group (PALG). Both therapies produced similar overall response rates (idelalisib plus rituximab 76.4% and ibrutinib 72.1%). Median progression-free survival (PFS) and overall survival (OS) in both groups were not reached. Furthermore, no significant difference was observed between both BCRi regimens in regard to PFS (HR=0.75, 95% CI=0.30-1.86, p=0.55) and OS (HR=0.65, 95%CI=0.26-1.68, p=0.39). In summary, the results of this retrospective analysis suggest that idelalisib combined with rituximab and ibrutinib therapies have comparable activity in r/r CLL/SLL in daily clinical practice.

Directory of Open Access Journals (Sweden)

Fernando Callera

Full Text Available CONTEXT AND OBJECTIVE: Geographical variations have been described in acute myelogenous leukemia (AML. In Brazil, few studies have been published on this. The aim of this study was to demonstrate the high prevalence of French-American-British (FAB M1 subtype in adults with de novo AML in São José dos Campos, State of São Paulo, Brazil. DESIGN AND SETTING: Retrospective analysis, at Hospital Pio XII in São José dos Campos, a public non-teaching institution. METHODS: Records from 39 consecutive adult patients with de novo AML referred to Hospital Pio XII between January 2002 and September 2004 were reviewed. Peripheral blood and blood marrow smears were reviewed blindly by five hematologists and classified according to FAB criteria. The rates of remission, relapse, mortality according treatment phase, survival and leukemia-free survival were calculated. RESULTS: The prevalence of each category as determined via a consensus among five observers was M0: 0%; M1: 43.6%; M2: 30.7%; M3: 12.8%; M4: 5.1%; M5: 2.6%: M6: 2.6%; and M7: 2.6%. The remission and the relapse rates were 82% and 41% respectively. The mortality rate was 69% (induction of remission: 7/39, 17.9%; post induction: 10/32, 31.2%; and relapse: 10/16, 62.5%. The survival rate was 30% and leukemia-free survival was 33%. CONCLUSIONS: The study demonstrated a high prevalence of FAB M1 subtype in adults with de novo AML in São José dos Campos. Our data suggest the occurrence of different regional prevalences of FAB AML categories in Brazil.

From January 1985 to May 1987, we studied 256 adults with newly diagnosed acute leukemia. Acute undifferentiated leukemia (AUL) was diagnosed in 12 of the 256 (4.6%) cases when lineage could not be delineated by light microscopy and light cytochemistry. To further characterize the blasts, immunophenotyping, ultrastructural myeloperoxidase (UMPO), and ultrastructural platelet peroxidase parameters were examined in 10, 11, and 6 of the 12 cases, respectively. Five cases demonstrated UMPO and were reclassified as acute myeloblastic leukemia (AML). Of the six UMPO-negative cases, three had a myeloid and one had a mixed immunophenotype. One UMPO-negative patient with a myeloid immunophenotype was probed for the immunoglobulin heavy chain gene (JH) and the beta chain of the T-cell receptor gene (Tcr beta) with no evidence of rearrangement. Six cases were treated with standard acute lymphoblastic leukemia (ALL) chemotherapy and failed to achieve complete remission (CR). Various AML chemotherapeutic regimens produced CR in only 3 of the 12 cases. One case was treated with gamma interferon and the other 2 with high-dose Ara-C. Our findings indicate a myeloid lineage can be detected by UMPO (5/12) in some cases of AUL. A germline configuration with JH and Tcr beta in one case as well as a myeloid immunophenotype in 3 UMPO-negative cases raises the possibility that myeloid lineage commitment may occur in the absence of myeloid peroxidase (MPO) cytochemical positivity.

Although there is effective chemotherapy for many patients with leukemia, 20% of children and up to 65% of adults relapse. Novel therapies are needed to treat these patients. Leukemia cells are very sensitive to the proteasome inhibitor bortezomib (VELCADE(R), PS-341), which enhances the in vitro cytotoxic effects of dexamethasone and doxorubicin in multiple myeloma. To determine if bortezomib enhances the cytotoxicity of agents used in leukemia, we employed an in vitro tetrazolium-based colorimetric assay (MTT) to evaluate the cytotoxic effects of bortezomib alone and in combination with dexamethasone, vincristine, doxorubicin, cytarabine, asparaginase, geldanamycin, trichostatin A, and the bcl-2 inhibitor HA14.1. We demonstrated that primary leukemia lymphoblasts and leukemia cell lines are sensitive to bortezomib, with an average IC(50) of 12 nM. Qualitative and quantitative bortezomib-drug interactions were evaluated using the universal response surface approach (URSA). Bortezomib was synergistic with dexamethasone in dexamethasone-sensitive leukemia cells, and additive with vincristine, asparaginase, cytarabine, and doxorubicin. The anti-leukemic activity of bortezomib was also additive with geldanamycin and HA14.1, and additive or synergistic with trichostatin A. These results were compared to analysis using the median-dose effect method, which generated complex drug interactions due to differences in dose-response curve sigmoidicities. These data suggest bortezomib could potentiate the cytotoxic effects of combination chemotherapy in patients with leukemia.

Secondary Leukemia Associated with the Anti-Cancer Agent, Etoposide, a Topoisomerase II Inhibitor

Full Text Available Etoposide is an anticancer agent, which is successfully and extensively used in treatments for various types of cancers in children and adults. However, due to the increases in survival and overall cure rate of cancer patients, interest has arisen on the potential risk of this agent for therapy-related secondary leukemia. Topoisomerase II inhibitors, including etoposide and teniposide, frequently cause rearrangements involving the mixed lineage leukemia (MLL gene on chromosome 11q23, which is associated with secondary leukemia. The prognosis is extremely poor for leukemias associated with rearrangements in the MLL gene, including etoposide-related secondary leukemias. It is of great importance to gain precise knowledge of the clinical aspects of these diseases and the mechanism underlying the leukemogenesis induced by this agent to ensure correct assessments of current and future therapy strategies. Here, I will review current knowledge regarding the clinical aspects of etoposide-related secondary leukemia, some probable mechanisms, and strategies for treating etoposide-induced leukemia.

To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis.We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition.Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002-1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063-0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338-1.934, P = .663).Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome.

Effects of intensive induction and consolidation chemotherapy with idarubicin and high dose cytarabine on minimal residual disease levels in newly diagnosed adult precursor-B acute lymphoblastic leukemia

Directory of Open Access Journals (Sweden)

Kenneth F. Bradstock

2016-12-01

Full Text Available An intensive induction regimen, consisting of idarubicin and high dose cytarabine, was assessed in 19 adult patients, median age 44 years, with newly diagnosed precursor-B acute lymphoblastic leukemia (ALL. Patients achieving a complete response (CR were given an attenuated consolidation course. The primary endpoints were induction death rate and incidence of serious non-hematological toxicity. Grades 3–4 diarrhoea occurred in 47% of patients during induction. Two patients (11% died during induction therapy, and 2 were withdrawn due to resistant disease or prolonged marrow hypoplasia. Fifteen patients achieved CR (79%, but levels of minimal residual disease (MRD after induction were comparable with those previously observed using a modified pediatric protocol. Overall survival at 5 years was 36.8% while leukemia-free survival was 44.1%. An intensive AML protocol used in adults with ALL resulted in substantial toxicity and provided similar levels of cytoreduction to conventional ALL protocols, without improving long-term outcomes.

To examine the neuropsychological outcomes for an adult patient, 2 years after receiving microsurgery and conventional radiotherapy for a recurrent craniopharyngioma; and the impact of a further intervention, stereotactic radiotherapy, on this level of neuropsychological functioning. JD, a 30 year old male whose recurrent craniopharyngioma had 2 years earlier been treated with two operations and conventional radiotherapy. JD was assessed (using standardized clinical tests) before and after a course of stereotactic radiotherapy. Prior to stereotactic radiotherapy (and 2 years after microsurgery and conventional radiotherapy) JD's IQ was intact, but considerable impairments were present in executive functioning, memory, theory of mind and processing speed. Fifteen months after stereotactic radiotherapy, all neuropsychological domains remained largely static or improved, supporting the utility of this treatment option in the neuropsychological domain. However, deficits in executive functioning, memory and processing speed remained. These findings suggest that, even after multiple treatments, substantial cognitive impairments can be present in an adult patient with a recurrent craniopharyngioma. This profile of deficits underlines the inadequacy of relying purely on IQ as a marker for cognitive health in this population and emphasizes the need to include neuropsychological impairments as a focus of rehabilitation with these patients.

Full Text Available We report here the case of a young adult affected by pre B-cell acute lymphoblastic leukemia (ALL, who developed, during a pediatric-like chemotherapy consolidation schedule with high dosage of Methotrexate, a severe neurological toxicity. Clinical presentation and neuroimaging data were diagnostic for posterior reversible encephalopathy syndrome (PRES. A complete resolution was quickly obtained with medical blood pressure control and anticonvulsants administration. To the best of our knowledge, this is the first case of PRES described in the adult ALL setting. Currently, the clinical management of this aggressive disease is moving towards a pediatric-like approach also in adult patients, due to the better outcome reached with intensive chemotherapeutic regimens in children population. However, therapy-related toxicities have to be taken into account, since their onset may adversely affect patients’ clinical outcome.

Acute lymphoblastic leukemia (ALL) is a relatively rare disease in adults accounting for no more than 20% of all cases of acute leukemia. By contrast with the pediatric population, in whom significant improvements in long term survival and even cure have been achieved over the last 30years, adult ALL remains a significant challenge. Overall survival in this group remains a relatively poor 20-40%. Modern research has focused on improved pharmacokinetics, novel pharmacogenetics and personalized principles to optimize the efficacy of the treatment while reducing toxicity. Here we review the pharmacogenetics of medications used in the management of patients with ALL, including l-asparaginase, glucocorticoids, 6-mercaptopurine, methotrexate, vincristine and tyrosine kinase inhibitors. Incorporating recent pharmacogenetic data, mainly from pediatric ALL, will provide novel perspective of predicting response and toxicity in both pediatric and adult ALL therapies.

Induction of complete remission (CR) is imperative for long-term survival in adult acute lymphoblastic leukemia (ALL) patients regardless of transplantation eligibility. Hyper-CVAD chemotherapy is a widely-used frontline remission induction regimen for these patients. We conducted a pilot trial of frontline remission induction using daunorubicin-augmented hyper-CVAD regimen (hyper-CVDD) in adult ALL patients (n = 15). The CR rate after this modified regimen was 100% (n = 15). Twelve patients were able to proceed to allogeneic hematopoietic cell transplantation, two patients died before transplantation due to infection, and the remaining one who was ineligible for transplant due to her age received an additional five courses of consolidation chemotherapy. Overall survival (OS) and event-free survival (EFS) of the study patients was 61.0 and 47.5% at 3 years. OS and relapse-free survival of transplanted patients was 66.8 and 55.0% at 3 years. This pilot trial demonstrates the favorable efficacy of the hyper-CVDD chemotherapy as a frontline remission induction regimen. Further clinical trials using this regimen are warranted.

T-cell-depleted, haploidentical transplantations (haplos) are commonly offered to patients who have high-risk, acute leukemia in the absence of a human leukocyte antigen (HLA) full-matched donor. To determine the effect of transplantation period, the authors divided 308 adults with de novo, acute leukemia who underwent T-cell-depleted haplo from 2005 to 2015 into 2 groups, according the year in which they underwent transplantation (2005-2011 [n = 191] and 2012-2015 [n = 117]). The median age was 41 years in patients who underwent transplantation before 2012 and 46 years in those who underwent transplantation after 2012 (P = .04). Most patients had acute myeloid leukemia (75% vs 69%; P = .26) and were in first complete remission (CR1) (55% vs 64%; P = .12) at the time of transplantation. The cumulative incidence of grade 2, 3, and 4 acute graft-versus-host disease (GvHD) and chronic GvHD were not different between the 2 groups (acute GvHD: 20% vs 22% cumulative incidence in patients who underwent haplo before and after 2012, respectively [P = .67]; chronic GvHD: 19% vs 11% cumulative incidence, respectively; P = .12]. The 2-year relapse incidence was 20%, the nonrelapse mortality (NRM) rate was 48%, and no difference was observed over time (21% vs 19% [P = .72] and 54% vs 38% [P = .11] for patients who underwent haplo before and after 2012, respectively). The main cause of NRM was infection. Haplo after 2012 (hazard ratio [HR], 0.57; P = .01), younger age (HR, 0.82; P = .02), and receipt of a reduced-intensity conditioning (RIC) regimen (HR, 0.53; P = .01) were independently associated with lower NRM. The 2-year overall survival rate was 36% and improved after 2012 (29% vs 47% before 2012; P = .02); and it was higher for patients who underwent transplantation in CR1 (41% vs 29%; P = .01). In multivariate analysis, haplo after 2012 (HR, 0.54; P = .003) and receipt of a RIC regimen (HR, 0.54; P = .005) were independently associated with better overall survival

Activating point mutation of the RAS gene has been generally accepted as an oncogenic event in a variety of malignancies. It represents one of the most common genetic alterations in acute myeloid leukemia (AML). However there is still controversy about its clinical relevance on the treatment outcome of this leukemia. Objective: This study aimed to clarify the biologic and prognostic impact of K-RAS mutations in relation to the dose of cytarabine (ara-C) used in post induction consolidation chemotherapy in adult AML patients. Patients and Methods: The study comprised 71de novo AML patients with a male: Female ratio of 1.4: 1; their ages ranged from 21-59 years with a median of 37 years. They were subjected to full clinical evaluation, routine laboratory investigations, cytogenetic studies by G banding and K-RAS mutation detection using realtime PCR. The patients were randomized into 2 groups (gps) according to the ara-C dose used in consolidation treatment, HDAC gp receiving 400 mg ara-C and LDAC gp receiving 100 mg ara-C. They were followed over a period of 5 years. Results: Mutations in the K-RAS gene (mutRAS) were detected in 23 patients (32%) with the remaining 48 patients (68%) having wild type RAS (wtRAS). Blast cell percentage was significantly lower in mutRAS compared to wtRAS patients (p=<0.001). The M4 subtype of AML and cases with Inv 16 showed significantly higher frequencies in mutRAS compared to wtRAS patients, (p=0.015, 0.003, respectively). The patients were followed up for a median of 43 months (range 11-57 months). There was no significant difference in overall survival (OS) between mutRAS and wtRAS patients (p=0.326). Within the mutRAS patients treated with HDAC, cumulative OS was significantly higher than those treated with LDAC (p=0.001). This was not the case in the wtRAS group (p=0.285). There was no significant difference in disease The Prognostic Impact of K-RAS Mutations in Adult Acute Myeloid Leukemia Patients Treated with High Dose

Splenic marginal zone lymphoma (SMZL), the most common primary lymphoma of spleen, is poorly understood at the genetic level. In this study, using whole-genome DNA sequencing (WGS) and confirmation by Sanger sequencing, we observed mutations identified in several genes not previously known to be recurrently altered in SMZL. In particular, we identified recurrent somatic gain-of-function mutations in NOTCH2, a gene encoding a protein required for marginal zone B cell development, in 25 of 99 (∼25%) cases of SMZL and in 1 of 19 (∼5%) cases of nonsplenic MZLs. These mutations clustered near the C-terminal proline/glutamate/serine/threonine (PEST)-rich domain, resulting in protein truncation or, rarely, were nonsynonymous substitutions affecting the extracellular heterodimerization domain (HD). NOTCH2 mutations were not present in other B cell lymphomas and leukemias, such as chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL; n = 15), mantle cell lymphoma (MCL; n = 15), low-grade follicular lymphoma (FL; n = 44), hairy cell leukemia (HCL; n = 15), and reactive lymphoid hyperplasia (n = 14). NOTCH2 mutations were associated with adverse clinical outcomes (relapse, histological transformation, and/or death) among SMZL patients (P = 0.002). These results suggest that NOTCH2 mutations play a role in the pathogenesis and progression of SMZL and are associated with a poor prognosis.

Linking Pesticide Exposure with Pediatric Leukemia: Potential Underlying Mechanisms

Full Text Available Leukemia is the most common cancer in children, representing 30% of all childhood cancers. The disease arises from recurrent genetic insults that block differentiation of hematopoietic stem and/or progenitor cells (HSPCs and drives uncontrolled proliferation and survival of the differentiation-blocked clone. Pediatric leukemia is phenotypically and genetically heterogeneous with an obscure etiology. The interaction between genetic factors and environmental agents represents a potential etiological driver. Although information is limited, the principal toxic mechanisms of potential leukemogenic agents (e.g., etoposide, benzene metabolites, bioflavonoids and some pesticides include topoisomerase II inhibition and/or excessive generation of free radicals, which may induce DNA single- and double-strand breaks (DNA-DSBs in early HSPCs. Chromosomal rearrangements (duplications, deletions and translocations may occur if these lesions are not properly repaired. The initiating hit usually occurs in utero and commonly leads to the expression of oncogenic fusion proteins. Subsequent cooperating hits define the disease latency and occur after birth and may be of a genetic, epigenetic or immune nature (i.e., delayed infection-mediated immune deregulation. Here, we review the available experimental and epidemiological evidence linking pesticide exposure to infant and childhood leukemia and provide a mechanistic basis to support the association, focusing on early initiating molecular events.

Chronic lymphocytic leukemia and chronic myeloid leukemia are the most common types of adult leukemia. However, it is rare for the same patient to suffer from both. Richter's transformation to diffuse large B-cell lymphoma is frequently observed in chronic lymphocytic leukemia. Purine analog therapy and the presence of trisomy 12, and CCND1 gene rearrangement have been linked to increased risk of Richter's transformation. The coexistence of chronic myeloid leukemia and diffuse large B-cell lymphoma in the same patient is extremely rare, with only nine reported cases. Here, we describe the first reported case of concurrent chronic myeloid leukemia and diffuse large B-cell lymphoma in a background of chronic lymphocytic leukemia. A 60-year-old Saudi man known to have diabetes, hypertension, and chronic active hepatitis B was diagnosed as having Rai stage II chronic lymphocytic leukemia, with trisomy 12 and rearrangement of the CCND1 gene in December 2012. He required no therapy until January 2016 when he developed significant anemia, thrombocytopenia, and constitutional symptoms. He received six cycles of fludarabine, cyclophosphamide, and rituximab, after which he achieved complete remission. One month later, he presented with progressive leukocytosis (mostly neutrophilia) and splenomegaly. Fluorescence in situ hybridization from bone marrow aspirate was positive for translocation (9;22) and reverse transcription polymerase chain reaction detected BCR-ABL fusion gene consistent with chronic myeloid leukemia. He had no morphologic or immunophenotypic evidence of chronic lymphocytic leukemia at the time. Imatinib, a first-line tyrosine kinase inhibitor, was started. Eight months later, a screening imaging revealed new liver lesions, which were confirmed to be diffuse large B-cell lymphoma. In chronic lymphocytic leukemia, progressive leukocytosis and splenomegaly caused by emerging chronic myeloid leukemia can be easily overlooked. It is unlikely that chronic myeloid

We performed a pilot study to test the effectiveness of allogeneic bone marrow transplantation in the treatment of chronic myelogenous leukemia. Five patients in the advanced stages of chronic myelogenous leukemia (four in blast crisis, one in accelerated phase) with abnormal chromosomes underwent matched-sibling allogeneic bone marrow transplantation after preparation with busulfan, vincristine, cyclophosphamide, and fractionated total body irradiation. Engraftment and conversion to normal chromosome patterns after transplantation occurred in all five patients. None of the patients reverted to an abnormal chromosome pattern or demonstrated clinical or hematologic evidence of recurrent disease during the course of this study; however, longest survival from transplant was 248 days. Allogeneic bone marrow transplantation can eradicate the abnormal clone even in far advanced chronic myelogenous leukemia and can provide normal hematopoiesis. We suggest that clinical complications of chemotherapeutic toxicity and infection were responsible for the short survival in this group of patients, and that these complications could be decreased by performing transplantation in the chronic phase or early accelerated phase of the disease

T-cell acute lymphoblastic leukemia (T-ALL) is a hematological malignancy characterized by the clonal proliferation of immature T-cell precursors. T-ALL has many similar pathophysiological features to acute myeloid leukemia, which has been extensively studied in the establishment of the cancer stem cell (CSC) theory, but the CSC concept in T-ALL is still debatable. Although leukemia-initiating cells (LICs), which can generate leukemia in a xenograft setting, have been found in both human T-AL...

Etoposide is an anticancer agent, which is successfully and extensively used in treatments for various types of cancers in children and adults. However, due to the increases in survival and overall cure rate of cancer patients, interest has arisen on the potential risk of this agent for therapy-related secondary leukemia. Topoisomerase II inhibitors, including etoposide and teniposide, frequently cause rearrangements involving the mixed lineage leukemia (MLL<...
