Abstract
Background: Chronic lymphocytic leukemia patients have an increased risk of secondary malignancy. Aim: The aim of the current study was to evaluate secondary malignancy in patients with chronic lymphocytic leukemia. Methods: Patients with chronic lymphocytic leukemia were screened and their diagnosis and last visit data, treatment protocols, the existence of secondary malignancy, if present, diagnosis date of secondary malignancy and its treatment were recorded from hospital system retrospectively. Results: One hundred thirty-four patient (134) followed in Hacettepe University Hospital Hematology Department were enrolled. Of 134, 88 (66%) were male and 46 (34%) were female. A total of 32 patients (23.9%) had a secondary malignancy. Of 32 patients, 8 were genito-urinary system (vulva - vagina - ovary - endometrium - prostate and renal) malignancies, 5 were dermatological system malignancies, 3 were thyroid, 2 were breast, 2 were lung, 1 was gastric and 9 were hematologic system malignancies. Mean age of patients with secondary malignancy were 64.2 ± 2.3 years and those without secondary malignancy were 64.1 ± 1.0 years ( P = 0.943). Mean overall survival in patients with secondary malignancy was 110 months and in those without secondary malignancy was 140 months ( P = 0. 531). 17 of the patients with secondary malignancy had a history of chemotherapy. 11 of these patients received chlorambusil-based treatments. Conclusion: Immune deficiency and chemotherapeutic agents used in the management of chronic lymphocytic leukemia are thought to be responsible for the appearance of secondary malignancies. Although there is no significant difference in terms of survival, these patients should be closely followed for secondary malignancies.

Abstract
Local bone marrow (BM) renin-angiotensin system (RAS) affects physiological and pathological haematopoiesis, including erythropoiesis. In this study, quantitative expression of the messenger RNAs of the major RAS components – angiotensin-converting enzyme (CD143), renin and angiotensinogen – were measured in BM samples by quantitative real-time polymerase chain reaction, to evaluate the activity of local BM RAS in polycythemia rubra vera (PV) in comparison with normal erythropoiesis. The presence of CD143 was also investigated in the same BM samples by flow cytometry. Increased local synthesis of the major RAS components has been identified by demonstrating corresponding mRNAs in the BM of the patients with PV. Our findings indicate up-regulation of local BM RAS, together with down-regulation of the cell surface angiotensin-converting enzyme receptors, in the autonomous neoplastic clonal erythropoiesis of PV.

Allogeneic hematopoietic SCT for adults AML using i.v. BU in the conditioning regimen: outcomes and risk factors for the occurrence of hepatic sinusoidal obstructive syndrome. Bone Marrow Transplant 2014; 49:628-33. [PMID: 24535127 DOI: 10.1038/bmt.2014.7] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2012] [Revised: 09/26/2013] [Accepted: 09/26/2013] [Indexed: 11/09/2022]
Abstract
I.v. BU is frequently used in the conditioning regimen prior to allogeneic hematopoietic SCT (allo-HSCT); however, overall outcomes, incidence of hepatic sinusoidal obstructive syndrome (SOS) and its risk factors are not well known. With this aim, we performed a study on 257 AML adult recipients. Seattle Criteria were used for diagnosis and classification of SOS. The median age was 44 years. Donors were HLA-identical siblings in 60%, HLA-matched unrelated in 29% and HLA mismatched in 11%. Conditioning regimen was myeloablative in 84% (i.v. BU with CY was the most frequently used regimen) and it was reduced intensity in 16% (i.v. BU associated with fludarabine). Acute and chronic GVHD was observed in 28% and 44%, respectively. Two-year incidence of non-relapse mortality was 16±2% and 2-year leukemia-free survival for patients in CR1, CR2 and non remission at HSCT were 55±4%, 58±7%, and 20±5%, respectively. At 6 months, incidence of SOS was 7.8±2%; and it was severe in eight patients (3%). Factors associated with the occurrence of SOS were: HLA-mismatched donor HSCT (P=0.002) and patients transplanted in non-remission (P=0.002). In conclusion, outcomes of HSCT using i.v. BU are encouraging in this setting, SOS incidence is low and it is influenced by the type of donor and disease status at the time of transplant.

Impact of in vivo T-cell depletion on outcome of AML patients in first CR given peripheral blood stem cells and reduced-intensity conditioning allo-SCT from a HLA-identical sibling donor: a report from the Acute Leukemia Working Party of the European Group for Blood and Marrow Transplantation. Bone Marrow Transplant 2014; 49:389-96.

Abstract
The impact of in vivo T-cell depletion on transplantation outcomes in patients transplanted with reduced-intensity conditioning (RIC) remains controversial. This study assessed the outcome of 1250 adult patients with de novo AML in first CR (CR1) given PBSC from HLA-identical siblings after chemotherapy-based RIC. A total of 554 patients did not receive any form of in vivo T-cell depletion (control group), whereas antithymocyte globulin (ATG) and alemtuzumab were given in 444 and 252 patients, respectively. The incidences of grade II-IV acute GVHD were 21.4, 17.6 and 10.2% in control, ATG and alemtuzumab patients, respectively (P<0.001). In multivariate analysis, the use of ATG and the use of alemtuzumab were each associated with a lower risk of chronic GVHD (P<0.001 each), but a similar risk of relapse, and of nonrelapse mortality, and similar leukemia-free survival and OS. Further, among patients given BU-based RIC, the use of <6 mg/kg ATG did not increase the risk of relapse (hazard ratio, HR=1.1), whereas there was a suggestion for higher relapse risk in patients given 6 mg/kg ATG (HR=1.4, P=0.08). In summary, these data suggest that a certain amount of in vivo T-cell depletion can be safely used in the conditioning of AML patients in CR1 given PBSC after chemotherapy-based RIC.

Abstract
Ankaferd Blood Stopper (ABS), a standardized mixture of five plants, has been used historically as a haemostatic agent but its mechanism of action remains unknown. This study investigated the in vitro effects of ABS on haemostatic parameters. When added to plasma or serum, ABS induced the very rapid formation of a protein network and erythrocyte aggregation. The levels of coagulation factors II, V, VII, VIII, IX, X, XI, and XIII were not affected by ABS. Plasma fibrinogen activity and antigen levels were decreased following the addition of ABS, in parallel with the prolonged thrombin time. Total protein, albumin, and globulin levels decreased after the addition of ABS. Our findings suggest that ABS stimulates the formation of an encapsulated protein network that provides focal points for erythrocyte aggregation. ABS has the therapeutic potential to be used for the management of haemorrhage and this agent should be investigated further in clinical trials.

Abstract
Gain of 12p material is invariably associated with testicular germ cell tumors (TGCTs) of adolescents and adults, most usually as an isochromosome 12p. We analyzed TGCTs with i(12p) using a global approach to expression profiling targeting chromosomes (comparative expressed sequence hybridization, CESH). This indicated overexpression of genes from 12p11.2-p12.1 relative to testis tissue and fibroblasts. The nonseminoma subtype showed higher levels of expression than seminomas. Notably, 12p11.2-p12.1 is amplified in about 10% of TGCTs and CESH analysis of such amplicon cases showed high levels of overexpression from this region. Microarray analysis, including cDNA clones representing most UniGene clusters from 12p11.2-p12.1, was applied to DNA and RNA from 5 TGCTs with amplification of 12p11.2-p12.1 and seven TGCTs with gain of the entire short arm of chromosome 12. Expression profiles were consistent with the CESH data and overexpression of EST595078, MRPS35 and LDHB at 12p11.2-p12.1 was detected in most TGCTs. High-level overexpression of BCAT1 was specific to nonseminomas and overexpression of genes such as CMAS, EKI1, KRAS2, SURB7 and various ESTs correlated with their amplification. Genes such as CCND2, GLU3, LRP6 and HPH1 at 12p13 were also overexpressed. The overexpressed sequences identified, particularly those in the region amplified, represent candidate genes for involvement in TGCT development.

Abstract
Two hundred and five patients referred for evaluation of platelet functions and 126 healthy controls were tested with the PFA-100 instrument. A cut-off value of 150 s for collagen/epinephrine (CEPI) closure time (CT) produced most acceptable sensitivity (90%), specificity (85.2%), and positive (82.6%) and negative (91.6%) predictivity values for screening of platelet function disorders and von Willebrand disease (vWD). All patients with vWD and Glanzmann thrombasthenia could be detected by PFA-100. Both CEPI and collagen/adenosine diphosphate (CADP) CTs were elevated in all of these cases. Sensitivity of the device was 81.6% for patients with platelet secretion defects. CADP CT was normal in 63.9% of the patients in this subgroup. Specificity (47%) and positive predictivity (57%) of the instrument were diminished in patients with low hemoglobin concentrations. Depending on the results, an algorithm was developed for screening of platelet function disorders and vWD with PFA-100.

Abstract
Many of the reported karyotypes for adult testicular germ cell tumors (GCTs) are complex and incomplete, although the presence of an isochromosome 12p, i(12p), and gain of 12p material have consistently been found. Here, an accurate definition of the chromosome aberrations associated with four cell lines derived from GCTs (GCT27, H12.1, Tera1, and Tera2) has been produced using 24-color karyotyping by mulifluor in situ hybridization, comparative genomic hybridization analysis, and further fluorescence in situ hybridization analysis to confirm some chromosomal assignments and refine involvement of specific regions of 12p. There was karyotypic heterogeneity. Isochromosomes in addition to i(12p) were found, as were other rearrangements with breakpoints at or near centromeric regions. The most frequent non-centromeric breakpoints were at 1p31 approximately p32, 1p21 approximately p22, 11q13, and Xq22, although consistent partner chromosomes were not involved. One cell line (Tera1) showed a subtle dosage increase in the copy number of a 12p probe known to be within the smallest overlapping region of amplification that has been defined in a number of testicular GCTs with amplicons at 12p11 approximately p12. The chromosome rearrangements and associated imbalances may be significant in GCT progression and the characterized cell lines can be used to investigate these further.

Abstract
Acute graft-vs-host disease (GVHD) is a major obstacle to safe allogeneic hematopoietic stem cell transplantation (HSCT), leading to a significant morbidity and mortality. GVHD occurs when transplanted donor T lymphocytes react to foreign host cells. It causes a wide variety of host tissue injuries. This review focuses on the pathobiological basis, clinical aspects, and current management strategies of acute GVHD. Afferent phase of acute GVHD starts with myeloablative conditioning, i.e., before the infusion of the graft. Total-body irradiation (TBI) or high-dose chemotherapy regimens cause extensive damage and activation in host tissues, which release inflammatory cytokines and enhance recipient major histocompatibility complex (MHC) antigens. Recognition of the foreign host antigens by donor T cells and activation, stimulation, and proliferation of T cells is crucial in the afferent phase. Effector phase of acute GVHD results in direct and indirect damage to host cells. The skin, gastrointestinal tract, and liver are major target organs of acute GVHD. Combination drug prophylaxis in GVHD is essential in all patients undergoing allogeneic HSCT. Steroids have remained the standard for the treatment of acute GVHD. Several clinical trials have evaluated monoclonal antibodies or receptor antagonist therapy for steroid-resistant acute GVHD, with different successes in a variety of settings. There are some newer promising agents like mycophenolate mofetil, glutamic acid-lysine-alanine-tyrosine (GLAT), rapamycin, and trimetrexate currently entering in the clinical studies, and other agents are in development. Future experimental and clinical studies on GVHD will shed further light on the better understanding of the disease pathobiology and generate the tools to treat malignant disorders with allogeneic HSCT with specific graft-vs-tumor effects devoid of GVHD.

Abstract
An estimated 10% of adult cancer patients present with undifferentiated carcinoma. The diagnosis of germ cell tumor (GCT) in such patients can be difficult but has important implications for patient management. Male testicular GCT is characterized by an isochromosome 12p, i(12p), or additional 12p material, in some cases restricted to the 12p11.2-p12.1 region. A gain of 12p material can indicate that a tumor, which may not be present in the testis, is of germ cell origin. Formalin-fixed, paraffin-embedded samples are the most widely available material for diagnostic analysis and retrospective studies. We have compared the identification of 12p gain in snap-frozen samples with corresponding paraffin-embedded material from three clearly defined testicular GCTs using comparative genomic hybridization analysis. In this preliminary study, paraffin-embedded tumor samples of uncertain histogenesis from seven patients were then analyzed. Tumor samples from three of these patients showed a gain of 12p material, and in one patient, gain was restricted to the 12p11.2-p12 region. The clinical picture and response to therapy were generally consistent with the 12p status, though lack of 12p gain may not exclude a diagnosis of GCT.

Abstract
A series of adult testicular germ cell tumours consisting of eight seminomas, 14 non-seminomas (including two cell lines) and two combined tumours was analysed by comparative genomic hybridization and, in some cases, by interphase fluorescence in situ hybridization. The gain of 12p was identified in all cases and additional material from chromosomes 7 and 8 was found in over 70% of cases, in keeping with previous analyses. Other consistent regions of gain included 1q24-q31 (50%), 2p16-pter (41%), 2q22-q32 (45%) and Xq11-q21 (50%). The loss of 1p32-p36 (36%), 9q31-qter (36%), 11q14-qter (50%), 16p (36%) and 18p (45%) and the loss of material from chromosomes 4 and 5 (50% and 36% respectively) were also found in all histological subtypes. The loss of 1p material was confirmed in four cases by interphase FISH analysis and shown, with one exception, not to involve the loss of the D1Z2 locus at 1p36.3, which is commonly deleted in paediatric germ cell tumours. An association between gain of 6q21-q24 with cases resistant to chemotherapy (P < 0.01) was observed. In addition, loss of chromosome 19 and 22 material and gain of 5q14-q23, 6q21-q24 and 13q were found at a significantly lower frequency in seminoma than non-seminoma. These regions may contain genes involved in the divergent development of seminoma and non-seminoma.

Abstract
OBJECTIVE To describe the clinical and biochemical features of patients in whom adrenal insufficiency developed during megestrol acetate therapy for advanced breast cancer. PATIENTS AND METHODS Thirteen patients with advanced breast cancer treated with oral megestrol acetate, 160 mg/d. RESULTS Fatigue and weakness were observed in all 13 patients. Hypotension was observed in 8. Anorexia, nausea, vomiting, and diarrhea were observed in 3. Mean basal cortisol level at the time of symptoms was 41.4 nmol/L (range, 27.6-110.4 nmol/L). After corticotropin stimulation, mean cortisol level at 30 minutes was 239.2 nmol/L (range, 93.8-447.0 nmol/L); at 60 minutes, 228.2 nmol/L (range, 88.3-474.5 nmol/L). CONCLUSION Megestrol therapy was associated with the development of clinical adrenal insufficiency in our patients, as proved by rapid corticotropin test.
