Abstract
The need for an individualized management of indolent clinical forms in mantle cell lymphoma (MCL) is increasingly recognized. We hypothesized that a tailored treatment with ibrutinib in combination with rituximab (IR) could obtain significant responses in these patients.

Abstract
Mutations in genes of the RAS-BRAF-MAPK-ERK pathway have not been fully explored in patients with chronic lymphocytic leukemia. We, therefore, analyzed the clinical and biological characteristics of chronic lymphocytic leukemia patients with mutations in this pathway and investigated the in vitro response of primary cells to BRAF and ERK inhibitors. Putative damaging mutations were found in 25 of 452 patients (5.5%). Among these, BRAF was mutated in nine patients (2.0%), genes upstream of BRAF (KITLG, KIT, PTPN11, GNB1, KRAS and NRAS) were mutated in 12 patients (2.6%), and genes downstream of BRAF (MAPK2K1, MAPK2K2, and MAPK1) were mutated in five patients (1.1%). The most frequent mutations were missense, subclonal and mutually exclusive. Patients with these mutations more frequently had increased lactate dehydrogenase levels, high expression of ZAP-70, CD49d, CD38, trisomy 12 and unmutated immunoglobulin heavy-chain variable region genes and had a worse 5-year time to first treatment (hazard ratio 1.8, P=0.025). Gene expression analysis showed upregulation of genes of the MAPK pathway in the group carrying RAS-BRAF-MAPK-ERK pathway mutations. The BRAF inhibitors vemurafenib and dabrafenib were not able to inhibit phosphorylation of ERK, the downstream effector of the pathway, in primary cells. In contrast, ulixertinib, a pan-ERK inhibitor, decreased phospho-ERK levels. In conclusion, although larger series of patients are needed to corroborate these findings, our results suggest that the RAS-BRAF-MAPK-ERK pathway is one of the core cellular processes affected by novel mutations in chronic lymphocytic leukemia, is associated with adverse clinical features and could be pharmacologically inhibited.

Abstract
Genome studies of chronic lymphocytic leukemia (CLL) have revealed the remarkable subclonal heterogeneity of the tumors, but the clinical implications of this phenomenon are not well known. We assessed the mutational status of 28 CLL driver genes by deep-targeted next-generation sequencing and copy number alterations (CNA) in 406 previously untreated patients and 48 sequential samples. We detected small subclonal mutations (0.6-25% of cells) in nearly all genes (26/28), and they were the sole alteration in 22% of the mutated cases. CNA tended to be acquired early in the evolution of the disease and remained stable, whereas the mutational heterogeneity increased in a subset of tumors. The prognostic impact of different genes was related to the size of the mutated clone. Combining mutations and CNA, we observed that the accumulation of driver alterations (mutational complexity) gradually shortened the time to first treatment independently of the clonal architecture, IGHV status and Binet stage. Conversely, the overall survival was associated with the increasing subclonal diversity of the tumors but it was related to the age of patients, IGHV and TP53 status of the tumors. In conclusion, our study reveals that both the mutational complexity and subclonal diversity influence the evolution of CLL.

Abstract
There is at present little data to guide the choice of conditioning for patients with lymphoma undergoing reduced-intensity conditioning (RIC) allogeneic stem cell transplantation (SCT). In this study, we compared the outcomes of patients undergoing RIC SCT who received fludarabine and melphalan (FluMel), the standard RIC regimen used by the Spanish Group of Transplantation, and fludarabine and busulfan (FluBu), the standard RIC regimen used by the Dana-Farber Cancer Institute/Brigham and Women's Hospital. We analyzed 136 patients undergoing RIC SCT for lymphoma with either FluBu (n = 61) or FluMel (n = 75) conditioning between 2007 and 2014. Median follow-up was 36 months. The cumulative incidence of grades II to IV acute graft-versus-host disease (GVHD) was 13% with FluBu and 36% with FluMel (P = .002). The cumulative incidence of nonrelapse mortality (NRM) at 1 year was 3.3% with FluBu and 31% with FluMel (P < .0001). The cumulative incidence of relapse at 1 year was 29% with FluBu and 10% with FluMel (P = .08). The 3-year disease-free survival rate was 47% with FluBu and 36% with FluMel (P = .24), and the 3-year overall survival rate was 62% with FluBu and 48% with FluMel (P = .01). In multivariable analysis, FluMel was associated with a higher risk of acute grades II to IV GVHD (HR, 7.45; 95% CI, 2.30 to 24.17; P = .001) and higher risk of NRM (HR, 4.87; 95% CI, 1.36 to 17.44; P = .015). The type of conditioning was not significantly associated with relapse or disease-free survival in multivariable models. However, conditioning regimen was the only factor significantly associated with overall survival: FluMel conditioning was associated with a hazard ratio for death of 2.78 (95% CI, 1.23 to 6.27; P = .014) compared with FluBu. In conclusion, the use of FluBu as conditioning for patients undergoing SCT for lymphoma was associated with a lower risk of acute GVHD and NRM and improved overall survival when compared with FluMel in our retrospective study. These results confirm the differences between these RIC regimens in terms of toxicity and efficacy and support the need for comparative prospective studies.

Abstract
AIM To determine the plasma and saliva levels of IL-6 in patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) and to investigate whether there is a correlation between more advanced stages of BRONJ and levels of IL-6. MATERIAL AND METHODS We studied three groups: group 1 consisted of 30 patients with BRONJ due to intravenous bisphosphonates (ivBP), group 2 consisted of 25 patients treated with ivBP but without BRONJ, and group 3 consisted of 15 healthy controls. In each case, we assayed plasma and saliva IL-6 samples using an ELISA test. RESULTS Significantly, higher IL-6 values were found in both saliva and plasma in group 1 vs groups 2 and 3 (P < 0.01). Group 1 showed no differences in plasma or saliva IL-6 according to patient gender (P > 0.05), type of tumor, BRONJ location, etiology of BRONJ, or disease stage (P > 0.05). We found higher plasma and saliva IL-6 values in the more advances stages of BRONJ, although the differences were not statistically significant. CONCLUSIONS Plasma and saliva IL-6 values were higher in our patients with BRONJ than in controls and therefore might be a useful tool for monitoring the severity of BRONJ.

Abstract
Therapy-related myelodysplasia and acute myeloid leukemia (t-MDS/AML) is a malignancy occurring after exposure to chemotherapy and/or radiotherapy. Polymorphisms involved in chemotherapy/radiotherapy response genes could be related to an increased risk of developing this neoplasia. We have studied 11 polymorphisms in genes of drug detoxification pathways (NQO1, glutathione S-transferase pi) and DNA repair xeroderma pigmentosum, complementation group (3) (XPC(3), X-ray repair cross complementing protein (1)), Nijmegen breakage syndrome (1), excision repair cross-complementing rodent repair deficiency, complementation group (5) and X-ray repair cross complementing protein (3) and in the methylene tetrahydrofolate reductase gene (MTHFR(2), 677C>T, 1298A>C), involved in DNA synthesis. The analyzed groups were a t-MDS/AML patients group (n=81) and a matched control group (n=64) treated similarly, and they did not develop t-MDS/AML. We found no significant differences when the groups were compared globally. However, when analysis was carried out according to the primary neoplasia involved, a significant association was observed between the MTHFR haplotype (single nucleotide polymorphisms 677 and 1298) and the risk of developing t-MDS/AML in the breast cancer patients group (P=0.016) and cyclophosphamide-treated hematological disease group (P=0.005). Risk haplotype was different for each case, corresponding to the 677T1298A haplotype after breast cancer treatment and the 677C1298C haplotype after hematological malignancy treatment. We postulate that such differences are related to variations in chemotherapy schemes between hematological and breast cancers and their differential interaction with the MTHFR route.

Abstract
The optimal approach to obtain an adequate graft for transplantation in patients with poor peripheral blood stem cell (PBSC) mobilization remains unclear. We retrospectively assessed the impact of different strategies of second-line stem cell harvest on the transplantation outcome of patients who failed PBSC mobilization in our institution. Such patients were distributed into three groups: those who proceeded to steady-state bone marrow (BM) collection (group A, n = 34); those who underwent second PBSC mobilization (group B, n = 41); those in whom no further harvesting was carried out (group C, n = 30). PBSC harvest yielded significantly more CD34+ cells than BM collection. Autologous transplantation was performed in 30, 23 and 11 patients from groups A, B and C, respectively. Engraftment data and transplantation outcome did not differ significantly between groups A and C. By contrast, group B patients had a faster neutrophil recovery, required less platelet transfusions and experienced less transplant-related morbidity, as reflected by lower antibiotics needs and shorter hospital stays. In conclusion, remobilization of PBSC constitutes an effective approach to ensure a rapid hematopoietic engraftment and a safe transplantation procedure for poor mobilizers, whereas unprimed BM harvest does not provide any clinical benefit in this setting.

Abstract
In B-cell chronic lymphocytic leukemia (B-CLL), somatic mutation of IgVH genes defines a subgroup with favorable prognosis, whereas the absence of IgVH mutations is correlated with a worse outcome. Mutations of the BCL-6 gene are also observed in a subset of B-CLL, but the clinical significance of this molecular alteration remains uncertain. We examined the distribution of IgVH and BCL-6 gene mutations in 95 well-characterized patients with Binet stage A B-CLL, and correlated them with clinical, laboratory, cytogenetic findings and disease progression. Mutations of the BCL-6 gene were observed only in cases harboring mutated IgVH. Unexpectedly, coexistence of IgVH and BCL-6 mutations was correlated with shorter treatment-free interval (TFI) compared to cases harboring only IgVH mutation (median, 55 months vs not reached; P=0.01), resembling the clinical course of unmutated IgVH cases (median TFI, 44 months). As expected, deletions of 17p13 (P53 locus) and 11q22 (ATM locus) were observed in cases with unmutated IgVH, except one patient who showed mutations of both IgVH and BCL-6. No other statistically significant differences were observed among the genetic subgroups. Our data indicate that BCL-6 mutations identify a subgroup of Binet stage A B-CLL patients with a high risk of progression despite the presence of mutated IgVH gene.

Abstract
BACKGROUND Patients with primary refractory Hodgkin's disease (PR-HD) have a dismal prognosis when treated with conventional salvage chemotherapy. We analyzed time to treatment failure (TTF), overall survival (OS) and clinical variables influencing the outcome in patients undergoing autologous stem cell transplantation (ASCT) for PR-HD and reported to the Grupo Español de Linfomas/Trasplante Autólogo de Médula Osea (GEL/TAMO). PATIENTS AND METHODS Sixty-two patients, 41 males and 21 females with a median age of 27 years (range 13-55) were analyzed. Forty-two patients (68%) had advanced stage at diagnosis, 47 (76%) presented with B symptoms and 29 (47%) with a bulky mediastinal mass. Seventy-five percent of the patients had received more than one line of therapy before ASCT. Thirty-three patients received bone marrow as a source of hematopoietic progenitors, and 29 peripheral blood. Six patients were conditioned with high-dose chemotherapy plus total-body irradiation and 56 received chemotherapy-based protocols. RESULTS One-year transplantation-related mortality was 14% [95% confidence interval (CI) 6% to 23%]. Response rate at 3 months after ASCT was 52% [complete remission in 21 patients (34%), partial remission in 11 patients (18%)]. Actuarial 5-year TTF and OS were 15% (95% CI 5% to 24%) and 26% (95% CI 13% to 39%), respectively. The presence of B symptoms at ASCT was the only adverse prognostic factor significantly influencing TTF [relative risk (RR) 1.75, 95% CI 0.92-3.35, P = 0.08]. The presence of B symptoms at diagnosis (RR 2.08, 95% CI 0.90-4.79, P = 0.08), MOPP-like regimens as first-line therapy (RR 3.84, 95% CI 1.69-9.09, P = 0.001), bulky disease at ASCT (RR 2.79, 95% CI 0.29-6.03, P = 0.009) and two or more lines of therapy before ASCT (RR 2.24, 95% CI 0.95-5.27, P = 0.06) adversely influenced OS. CONCLUSIONS In our experience, although overall results of ASCT in PR-HD patients are poor, one-quarter of the patients remain alive at 5 years. Despite this, other therapeutic strategies should be investigated in this group of patients to improve the outcome.

Abstract
BACKGROUND High serum levels of soluble intercellular adhesion molecule-1(s-ICAM-1/s-CD54) have been associated with adverse clinical features and poor outcome in chronic lymphocytic leukemia, Hodgkin's disease and non-Hodgkin's lymphoma, but their value in the different subtypes of non-Hodgkin's lymphoma has not been well addressed. PATIENTS AND METHODS Our aim was to study the serum levels of s-ICAM-1 in diffuse large B-cell lymphoma (DLBCL) and to correlate them with clinical characteristics and outcome. We analyzed the serum levels of s-ICAM-1 in a series of 55 patients with DLBCL diagnosed in a single institution. s-ICAM-1 levels were quantified by an immunoenzymatic assay. Median age was 62 years (range 22-96); 29 (53%) were male. Twenty-eight (51%) presented with advanced clinical stage (III/IV), 32 (58%) had extranodal involvement, 28 (51%) had high serum lactate dehydrogenase (LDH) and 23 (43%) had high beta2-microglobulin levels. All patients received anthracycline-containing regimens. Correlation between clinical variables and s-ICAM-1 levels were tested with the Mann-Whitney U-test and survival was plotted by the Kaplan-Meier method, and curves compared with the log-rank test. RESULTS Serum levels of s-ICAM-1 were significantly increased in patients with DLBCL compared with normal controls (589 +/- 487 versus 279 +/- 65 ng/ml, respectively; P <0.001). Higher levels of s-ICAM-1 were present in patients with B symptoms, advanced stage and increased LDH and beta2-microglobulin. s-ICAM-1 levels also correlated with achievement of a complete response. Patients with s-ICAM-1 over 668 ng/ml had a shorter time to treatment failure (TTF) (3-year TTF, 59% versus 20%, respectively; P = 0.01) and overall survival (OS) (3-year OS, 58% versus 22%, respectively; P = 0.04) than the remainders. When only low and low-intermediate risk patients in the international prognostic index score were considered, those with s-ICAM-1 over 668 ng/ml also had worse TTF and OS. CONCLUSIONS In DLBCL, s-ICAM-1 levels correlated with high tumor burden and lymphoma dissemination and may contribute to assessment of prognosis.

Abstract
INTRODUCTION Mantle cell leukemia (MCLeu) has been considered as a leukemic form of mantle cell lymphoma (MCL). However, the presence of certain features rarely observed in MCL, such as transformation to prolymphocytic leukemia (PLL) or indolent clinical course, suggests that MCLeu may represent a distinct disorder. METHODS Seven cases of MCLeu with t(11;14)(q13;q32) and BCL1-IGH gene rearrangement were ascertained among 140 newly diagnosed chronic B-cell lymphoproliferative disorders with leukemic expression. Comparative genomic hybridization, FISH for specific gene loci, and immunological studies were preformed in them. RESULTS In comparison with CLL, MCLeu cases had low immunological scores < or =2 with respect to B-CLL (P<0.0001). Expression of CD38 was absent in 43% of MCLeu and in 44% of B-CLL. Comparative genomic hybridization analysis identified genomic imbalances in 86% of MCLeu with a similar pattern than in MCL: gains of 3q, 8q involving MYC gene and 15q, and losses of 6q, 9p, 13q and 17p affecting P53 gene. Differently from MCL and CLL, genomic loss of 8p was frequently detected in MCLeu (83%). Although clinical presentation of MCLeu was indistinguishable from CLL, all patients but one had disease progression within three years. According to the immunologic and genomic profiles, two distinct subgroups of MCLeu were defined: one related to PLL, showing CD38-, deletion of P53, and MYC amplification and another which corresponds to a leukemic form of classical MCL, presenting with CD38+ and normal P53 and MYC status. CONCLUSION MCLeu and MCL are closely related disorders, as they show similar genomic and molecular patterns. However, the deletion of the short arm of chromosome 8 may represent a specific marker for MCLeu. Two distinct subgroups of MCLeu may also be distinguished according to the immunologic and genomic cell profiles.

Abstract
Patients with mantle cell lymphoma (MCL) may present with either nodal or leukemic disease. The molecular determinants underlying this different biologic behavior are not known. This study compared the pattern of genetic abnormalities in patients with nodal and leukemic phases of MCL using comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) for specific gene loci. Although both leukemic and nodal MCL showed similar genomic patterns of losses (involving 6q, 11q22-q23, 13q14, and 17p13) and gains (affecting 3q and 8q), genomic loss of chromosome 8p occurred more frequently in patients with leukemic disease (79% versus 11%, P <.001). Subsequent CGH analysis confirmed the genomic loss of 8p21-p23 in 6 of 8 MCL cell lines. Interestingly, MYC gene amplification was restricted to cases with 8p deletion. These data indicate the presence of a novel tumor suppressor gene locus on 8p, whose deletion may be associated with leukemic dissemination and poor prognosis in patients with MCL.

Abstract
The Spanish PETHEMA group designed a protocol for newly diagnosed PML/RARalpha-positive acute promyelocytic leukemia (APL) in which induction and consolidation followed the original AIDA regimen, except for the omission of cytarabine and etoposide from consolidation. Induction consisted of 45 mg/m(2) all-trans retinoic acid (ATRA) daily until complete remission (CR) and 12 mg/m(2) idarubicin on days 2, 4, 6, and 8. Patients in CR received 3 monthly chemotherapy courses: idarubicin 5 mg/m(2)/d x 4 (course no. 1), mitoxantrone 10 mg/m(2)/d x 5 (course no. 2), and idarubicin 12 mg/m(2)/d x 1 (course no. 3). Maintenance therapy consisted of 90 mg/m(2)/d mercaptopurine orally, 15 mg/m(2)/wk methotrexate intramuscularly, and, intermittently, 45 mg/m(2)/d ATRA for 15 days every 3 months. Between November 1996 and December 1998, 123 patients with newly diagnosed PML/RARalpha-positive APL from 39 centers were enrolled. A total of 109 patients achieved CR (89%; 95% confidence interval [CI], 83 to 95), 12 died of early complications, and the remaining 2 were resistant. Consolidation treatment was associated with very low toxicity and no deaths in remission were recorded. Molecular assessment of response by reverse transcriptase-polymerase chain reaction (RT-PCR) showed conversion to PCR-negative in 48 of 99 (51%) and 82 of 88 patients (93%) after induction and consolidation, respectively. The 2-year Kaplan-Meier estimates of overall survival and event-free survival were 82% +/- 4% and 79% +/- 4%, respectively. For patients who achieved CR, the 2-year disease-free survival (DFS) was 92% +/- 3%. These data indicate that a significant reduction in toxicity might be obtained in APL using a less intensive consolidation without apparently compromising the antileukemic effect. These results also suggest a minor role for cytarabine and etoposide in the treatment of newly diagnosed PML/RARalpha-positive APL patients.

Abstract
We investigated the effectiveness of a new treatment regimen termed NOVP in early Hodgkin's disease, which reportedly has lower toxicity. Thirty-four patients were treated with three cycles of NOVP (mitoxantrone, vinblastine, vincristine, prednisone) and radiotherapy, 40% of them had unfavourable prognostic factors. All patients obtained complete remission. With a median follow up of 5 years, the overall survival (OS) and time to treatment failure (TTF) was 95% (95% confidence interval [CI], 87 to 103) and 89% (95% CI, 78 to 100), respectively. The presence of either B symptoms or pulmonary hilar involvement was associated with a significant decrease in TTF (91% VS 50% p=0.003 and 92% VS 30% p=0.02, respectively) but do not correlate with OS. The tolerance to NOVP was excellent with minimal toxicity. In conclusion, this regimen is associated with a favourable outcome and low toxicity in stage I and II Hodgkin's disease, although patients with B symptoms and pulmonary hilar involvement have a higher risk of relapse.

Abstract
PURPOSE To analyze beta-integrin expression in non-Hodgkin's lymphomas (NHLs) in order to assess its distribution among histologic subtypes and correlate with clinical features and outcome. PATIENTS AND METHODS The expression of alpha2 through alpha6 and beta1 common chains of very late activation antigen (VLA ) molecules and alphaL (CD11a) and beta2 common (CD18) chains of leukocyte function-associated antigen 1 molecule were studied in 137 patients with NHL. Immunostaining was performed by a streptavidin-biotin alkaline phosphatase method, and integrin expression was semiquantitatively assessed. Correlation with clinical features was analyzed in 80 patients consecutively diagnosed as having immunocytoma (five cases), follicular lymphoma (19 cases), mantle-cell lymphoma (MCL; four cases), diffuse large-cell lymphoma (DLCL; 40 cases), lymphoblastic lymphoma (LL; six cases), anaplastic Ki-1-positive lymphoma (one case), and other peripheral T-cell lymphoma (five cases). RESULTS MCL cells did not show alpha2 and alpha6 expression, whereas most expressed weak to moderate levels of alpha3, alpha4, and alpha5. LL mostly showed alpha2 to alpha5 expression, whereas alpha6 was observed in seven of 11 cases (higher proportion than that shown in other subgroups). Alpha chains of VLA molecules were present more frequently in T-cell than in B-cell lymphomas. Patients with moderate/strong alpha4, CD11a, and beta2 common chain expression presented more frequently with advanced stage and bone marrow infiltration. Moderate/strong alpha4, alpha5, and beta1 common chain expression correlated with extranodal involvement. In the subset of B-cell DLCL patients, negative/weak expression of alpha3 and alpha4 chains was related to a higher complete response rate. Moreover, negative or weak expression of alpha2, alpha3, alpha4, and beta1( )common chain had favorable significance for overall and failure-free survivals. CONCLUSION In NHL, beta-integrin expression is related to histologic subtype. The expression pattern of these molecules probably influences disease dissemination and patients' prognoses.

Abstract
The inv(16) and t(16;16) characterize a subgroup of acute myelomonocytic leukemia (AML) with distinct morphological features and a favorable prognosis. Both cytogenetic abnormalities result in a fusion of CBF beta at 16q22 and MYH11 gene at 16p13, whose detection by PCR and fluorescence in situ hybridization (FISH) is useful for diagnosis and monitoring of the disease. Variant translocations of inv(16)/t(16;16) are very rare and whether they are also associated with a favorable prognosis is unknown. We report a patient presenting with typical AML-M4Eo and a three-way translocation of inv(16) involving 16p13, 16q22, and 3q22. FISH studies on bone marrow (BM) chromosomes using CBFB and MYH11 DNA probes revealed a fusion of CBFB and MYH11 on 16q of the der(16), as well as a signal from MYH11 on 16p but not from CBFB; normal signals for both probes were present on the normal 16. Neither of these labeled probes was on the der(3), but the translocation between the der(3) and der(16) was confirmed by using a chromosome 16 painting probe. Molecular analysis of BM cells using RT-PCR identified a CBFB-MYH11 fusion transcript type D. After achieving complete remission, the patient relapsed. We conclude that FISH and PCR are feasible tools to distinguish cases with variant abnormalities of inv(16) from cases with other chromosome 16 abnormalities. Variant abnormalities of inv(16) may be not associated with favorable prognosis.

Abstract
PURPOSE To study the expression of intercellular adhesion molecule-1 (ICAM-1) by non-Hodgkin's lymphomas and to assess its correlation with disease extension and prognosis. PATIENTS AND METHODS ICAM-1 (CD54-IOL54) expression was studied in 70 patients (35 male/35 female; median age, 56 years) with non-Hodgkin's lymphoma from a single institution. Immunostaining was performed using a streptavidine-biotin alkaline phosphatase method and ICAM-1 expression was evaluated in a semiquantitative manner. The histologic distribution of the cases was the following: small lymphocytic, five cases; follicular, 14; mantle cell, five; diffuse large cell, 41; and T lymphoblastic, five. Forty patients (57%) were in stage IV, bulky disease was observed in 25 patients (36%), and extranodal involvement in 48 patients (69%). RESULTS ICAM-1 expression was negative (-) in 14 patients (20%), weak (+) in 21 (30%), positive (++) in 30 (43%), and strongly positive ( ) in five (7%). No significant relationship was found between ICAM-1 expression and the lymphoma histologic subtype. Patients with negative or weak ICAM-1 expression had more frequently disseminated (stage IV) disease (74% v 40%; P = .007), extranodal involvement (86% v 51%; P = .004), and bone marrow infiltration (57% v 26%; P = .015) than the remainders. Positive ICAM-1 patients had survival rates significantly better than those in whom ICAM-1 was negative or weakly expressed [2-year overall survival: 77% v 50%, respectively; P < .025]. In a multivariate study, ICAM-1 (P = .005) maintained, along with histologic subtype (P = .001) and the international prognostic index (IPI) (P = .056), its importance for predicting survival. Finally, when the group of aggressive non-Hodgkin's lymphoma patients was analyzed, ICAM-1 expression inversely correlated with advanced stage (P = .025), extranodal involvement (P = .01), and bone marrow infiltration (P = .01), complete response (CR) achievement (65% v 32%; P = .025), and overall survival (70% v 26% at 2 years; P < .005). CONCLUSION In lymphoma patients, ICAM-1 expression correlates with lymphoma dissemination and is useful to assess prognosis.

Abstract
ICAM-3/CD50 is a recently described LFA-1 counter receptor that seems to play an important role in the initiation of immune responses. In this study we have examined the expression of ICAM-3/CD50 in a large series of human neoplasms including 101 Non-Hodgkin's lymphomas (NHL), 26 Hodgkin's disease, and 38 solid tumors to define the distribution patterns of this molecule in malignant neoplasms and their possible correlation with clinical and pathological characteristics of the patients. In NHL, ICAM-3/CD50 was expressed in almost all the tumors with a tendency to be lost in high grade lymphomas. Reed-Sternberg cells and their variants in Hodgkin's disease were always negative independently of the histological subtype of the disease. No expression was observed in tumor epithelial cells of the 38 solid tumors examined. Strong endothelial cell staining was observed in 31% of the NHL and 31% of Hodgkin's disease. ICAM-3 expression in these cases was restricted to small tumor vessels. ICAM-3 expression in endothelial cells of NHL was significantly more frequent in high grade (40%) than in low grade lymphomas (14%) (p = 0.012). In addition, tumor vessels were also positive in 29% of solid tumors independently of the histological type. No correlation was observed between ICAM-3 expression in tumor or endothelial cells and other clinical and pathological characteristics of the patients. These findings indicate that ICAM-3 expression in human tumors is restricted to hematological neoplasms with a tendency to be lost in high grade lymphomas and Hodgkin's disease. ICAM-3 is also expressed by endothelial cells from tumor-associated neovascularization in both lymphoid and solid tumors.

Abstract
In order to assess the relative importance of the clinicohematological features most commonly associated with the accelerated phase (AP) of chronic myeloid leukemia (CML) in 175 consecutive patients, 12 variables generally considered as indicating AP were analyzed for their predictive value for blast crisis (BC) appearance in less than 1 yr. At the time of analysis, 118 patients had died and 104 had developed BC. At univariate study, 6 features were associated with a significantly higher BC-probability: poor performance status (ECOG score > or = 2), unexplained fever/sweats, severe bone pain, progressive splenomegaly despite adequate therapy, blood basophils (> or = 20%) and peripheral blasts (6-12%). At logistic regression, only bone pain and blood blasts (6-12%) retained their prognostic importance; the relative risk of unexplained fever/sweats and progressive splenomegaly was also clinically relevant. One-year BC-probability from the appearance of 1 or more of the above features was 77.3% (95% CI: 66-86.6) and 100% since all 4 were observed. Finally, at least 1 of the 4 features was present prior to death in 6 of 7 patients dying from CML-related causes while not in BC. AP can be defined by the appearance along CML evolution of 1 or more of the 4 above-mentioned clinicohematological features.

Abstract
The performance of a leukocyte reduction bedside filter with different types of RBC concentrates was analyzed. Three types of RBCs were prepared: buffycoat-depleted RBCs suspended in saline-adenine-glucose-mannitol (SAGM)-additive solution (BC-RBCs; n = 20), RBCs suspended in SAGM-additive solution without buffy coat removal (SAGM-RBCs; n = 20), and RBCs drawn in CPDA-I conservative solution and processed for component preparation by the platelet-rich plasma method (CPDA-RBCs; n = 20). The units were filtered within 8 h of collection. One filter was used for every 2 units. High numbers of residual WBCs were found even in the units filtered first. Filtration of CPDA-RBCs resulted in a higher residual WBC content than SAGM-RBCs or BC-RBCs (p = 0.0032 and p = 0.0002, respectively). The filter performance strikingly decreased when the WBC load per filter exceeded 4 x 10(9) or the platelet load was less than 100 x 10(9). We conclude that filter performance varies with the WBC and platelet content of the RBC concentrates. Under the experimental conditions assayed in this study CPDA-RBCs are the least appropriate ones to be used for bedside leukocyte reduction.

Abstract
The t(11;14)(q13;q32) translocation and its molecular counterpart bcl-1 rearrangement are highly characteristic of mantle cell lymphomas (MCLs). Most of these translocations occur at the major translocation cluster (MTC) in a tight area that makes this rearrangement identifiable by the polymerase chain reaction (PCR). In this study, the specificity and sensitivity of the PCR technique in the identification of bcl-1 rearrangement and its suitability to amplify the t(11;14) MTC in fixed, paraffin-embedded tissues were analyzed. Genomic DNA was obtained from 21 MCLs and 1 chronic lymphocytic leukemia (CLL) with the t(11;14) translocation. The bcl-1 rearrangement was studied by Southern blot with the MTC, p94PS, and PRAD-1 probes. Polymerase chain reaction was performed using a JH consensus primer and specific primers for chromosome II in the MTC region. bcl-1 rearrangement was identified by Southern blot in the MTC in nine (43%) MCLs and in the p94PS region in the CLL. Polymerase chain reaction analysis of genomic DNA showed that the nine MCLs with MTC rearrangement also had an amplifiable band of the expected size (100%). No amplifiable products were detected in the negative MCLs or in the CLL. The specificity of the PCR products was confirmed by hybridization with an internal MTC oligonucleotide probe. Amplifiable DNA was obtained from the paraffin blocks of 7 cases with MTC rearrangement and 11 negative tumors. bcl-1 rearrangement was detected in this DNA of 6 positive MCLs (86%) by PCR and in none of the negative cases. In conclusion, this study demonstrates that the PCR technique is highly sensitive and specific for the detection of the bcl-1 rearrangement at the MTC. It can be used with both high molecular weight DNA and DNA obtained from formalin-fixed, paraffin-embedded tissues.

Abstract
PURPOSE In non-Hodgkin's lymphomas, CNS involvement is highly dependent on the histology of the lymphoma. Mantle-cell lymphoma (MCL) is a lymphoma type with distinctive histologic, biologic, and clinical features in which CNS involvement has only been rarely described. The purpose of this report is to describe the incidence, clinical characteristics, and outcome of CNS infiltration in patients with MCL seen at a single institution. PATIENTS AND METHODS Twenty-two patients with MCL, who account for 6% of all patients with nodal lymphomas diagnosed and monitored at a university hospital from 1987 to 1994, were studied. Analysis of the incidence of CNS involvement by the disease was performed. RESULTS Five of 22 patients (22%; exact 95% confidence interval [CI], 7.8% to 45.4%) with MCL developed CNS involvement at a median of 18 months (range, 6 to 59) from diagnosis. All of these patients presented with poor MCL histologic subtypes and advanced disease. When the CNS infiltration became apparent, all of the patients displayed neurologic signs and had lymphoid cells consistent with the diagnosis of MCL in the CSF. In most of the cases, CNS infiltration was part of resistant disease or generalized relapse and had an ominous significance. CONCLUSION The incidence of CNS involvement in MCL might be higher than previously recognized. The frequency of CNS infiltration in MCL deserves to be investigated in other series and, if a high incidence is confirmed, the risk factors, mechanisms, and clinical implications of such a complication should be further studied.

Abstract
Clinical features and prognostic factors were analyzed in a series of 117 patients with localized non-Hodgkin's lymphoma (stage I-II). Median age of the patients was 53 years and 52% were men; 22% had a lymphoma of low-grade histology and one-third presented with extranodal involvement. Eighty percent of the patients achieved a complete response (CR); stage of disease and histology were revealed as the most important factors for response. When analysis was restricted to intermediate/high-grade cases, stage showed a predictive value for response. With a median follow-up of 4.5 years, median overall survival was 12.0 years, with 73% and 62.5% of patients being alive at 5 and 10 years, respectively. Main initial parameters significantly related to a shorter survival were intermediate/high-grade histology, stage II, poor performance status, bulky disease, high serum LDH levels, increased ESR, and advanced International Index. In the multivariate analysis, stage, histology and performance status (PS) were statistically significant. Among intermediate/high-grade lymphoma patients, stage and PS provided prognostic value for survival. Twenty-six patients relapsed after CR; median survival after relapse was 2.7 years. Stage (I vs II) was the only predictive variable for relapse in both the whole series and the intermediate/high-grade subset.

Abstract
PURPOSE To analyse the initial and evolutive characteristics of the patients with low-grade lymphoma and long survival (> or = 12 years). MATERIAL AND METHODS The initial data (clinical, laboratory, histologic type, stage) and the clinical course (response to therapy, response duration) of 52 patients with low-grade lymphoma diagnosed before 1980 were analysed. The statistical study was carried out by means of the chi-square test with Yates' correction and Student's t; the actuarial survival was estimated, and the duration of remission was assessed by the Kaplan and Meier method. Curves were compared by the log rank method. RESULTS The 12-year survival as a whole was 32% (CI: 95%: 18.5%-45.5%). Of the 52 patients, 13 (25%) survived over 12 years. Nine were men and 4 women, with median age of 41 years (range: 22-68 years). Three cases had lymphocytic lymphoma and 10 had follicular lymphoma; 2 were in stage I-II and 11 in stage III-IV. Those patients who would become long-survivors had at diagnosis lesser frequency of spread lymph-node regional involvement (> or = 3 sites): 46% vs 81.8%, p = 0.04, as well as lesser percentage of bone-marrow involvement (38.4% vs 78.1%, p = 0.023). They were also better responders to treatment (CR+PR = 100% vs 71%, p = 0.013) and with longer duration (actuarial median duration of response 8 years vs 1.5 years, p = 0.005). CONCLUSIONS According to the present analysis, low-grade lymphoma patients who have at diagnosis low tumoral involvement (not too extensive lymph-node involvement, disease-free bone-marrow) and show good response to treatment have a better prognosis and may hope for a longer survival.

Abstract
The aim of the present study was to analyze the main clinical and evolutive characteristics of a series of 10 patients diagnosed with sepsis by Candida tropicalis over a 5-year period in a Hematology Unit. The mean age of the 10 patients was 23 years (range 13-66 years) with 6 males and 4 females. Eight patients had acute leukemia, 1 non-Hodgkin's lymphoma and another patient had severe bone marrow aplasia. All the patients presented intense granulocytopenia (< 0.5 x 10(9)/L), had intravenous catheters and were receiving wide spectrum antibiotics as treatment for bacterial infection. The diagnosis of the fungal infection was based on the growth of C. tropicalis in blood cultures together with the evidence of tissue involvement by the fungus. Fever (> 38 degrees C) was the initial symptom of the infection in all the patients, being accompanied by myalgia in 5 cases, pleuritic pain in 2 and septic shock in 1. Violaceous erthymatomous pustules disseminated over the trunk and limbs, the histologic study of which demonstrated the presence of C. tropicalis were observed in 9 patients. Septic metastasis were found in the liver (2 cases), serosae (2 cases), the psoas muscle and the brain (1 case), respectively. Eight patients underwent treatment with amphotericin B which was complemented with 5-fluorocytosin in 6, with death occurring in the remaining 2 patients prior to the start of treatment. Three patients died with active fungal infection (2 by cerebral hemorrhage and 1 by septic shock). In 2 patients the infection evolved to chronic systemic candidiasis and in the remaining 5 patients infection was resolved with hemoperipheral values returning to normal. Sepsis by Candida tropicalis is a severe complication in patients with granulocytopenia, being mainly characterized by fever, cutaneous papulae and, to a lesser extent, muscle pain. Amphotericin B alone, or in combination with 5-fluorocytosin constitute a treatment of choice in this infection, which nonetheless is associated with an undisdainful mortality.

Abstract
Clinical and prognostic studies were carried out in a series of 143 patients with low-grade (small-lymphocytic, follicular small cleaved cell, follicular mixed small- and large-cell) lymphoma. After treatment with alkylating agents (21.5% cases), combination chemotherapy (73.3%) or other therapies (5.2%), complete response (CR) was obtained in 40.7% of cases and partial response (PR) in 43.7%. The stage of the disease was the most important factor for response. With a median follow-up of 6.5 years, 48.0% (95% Cl: 37.5-58.5) of patients were alive 10 years after diagnosis. Among the initial parameters, advanced stage. B-symptoms, poor performance status, nodal involvement > 3 sites, extranodal involvement > or = 2 sites, WBC count > or = 10 x 10(9)/L, leukemic expression, high serum LDH levels, and bone marrow infiltration were all related to survival; treatment modality, however, had no influence on survival. In the multivariate analysis, stage (p = 0.008) and age (p = 0.053) were the most important prognostic factors. When considering response to therapy, both CR (p < 0.001) and PR (p = 0.003) emerged as the most important predictive variables, with only the absence of B-symptoms retaining its prognostic significance (p = 0.014) among the other parameters. In addition, in CR patients the duration of the response (< or = 1 year vs. > 1 year) was the most significant parameter for survival (p < 0.001). Finally, the initial stage (p = 0.011) and the histologic subtype (those patients with follicular mixed lymphoma relapsing less frequently than the others) (p = 0.052) were the only significant factors for relapse.

Abstract
The efficacy of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) in graft failure after bone marrow transplantation (BMT) has been evaluated in 25 patients. rhGM-CSF was administered intravenously at a dose of 5 or 10 micrograms/kg. Fourteen patients (seven allogeneic BMT [allo-BMT], seven autologous BMT [ABMT]) were treated for primary bone marrow failure (no granulocyte recovery after BMT), and 11 cases (all allo-BMT) received rhGM-CSF for secondary bone marrow failure (absolute neutrophil count lower than 0.5 x 10(9)/L after a previously sustained granulocyte recovery). Two allo-BMT and three ABMT patients with primary bone marrow failure achieved a granulocyte response to rhGM-CSF. In contrast, nine patients with primary graft failure did not respond to rhGM-CSF (four ABMT, three HLA-identical T-depleted BMT, one minor mismatch BMT, one unrelated BMT). Ten of 11 allo-BMT patients treated for secondary bone marrow failure attained an ANC higher than 0.5 x 10(9)/L, but most became severely neutropenic again at a median time of 4 weeks. The possible cause triggering graft failure (graft-vs.-host disease [GVHD], cytomegalovirus [CMV] infection) remained unsolved in most of these cases. Actuarial probability of survival of the entire series was 16 +/- 9% at 15 months. The severity of graft failure and the presence of other concomitant complications in most of our patients may justify these poor results. In conclusion, rhGM-CSF had less efficacy in patients with primary bone marrow failure than in those with secondary bone marrow failure. In the latter setting, measures addressed to correct the initial cause of graft failure are mandatory.

Abstract
PURPOSE Variables used to build up the International Index for aggressive lymphomas (age, performance status, stage, extranodal involvement, and lactic dehydrogenase [LDH]) are also important in low-grade lymphoma. To assess the prognostic value of this index in low-grade lymphoma, we have applied it to a series of 125 patients. PATIENTS AND METHODS One hundred twenty-five patients with low-grade lymphoma who were diagnosed at a single institution over a 20-year period and treated with standard chemotherapy were studied. End points of the study were response to therapy and survival according to the International Index. In addition to the International Index, main initial and evolutive variables were evaluated. Univariate and multivariate methods were used. RESULTS After applying the International Index, the patients divided into four risk groups: low (36% of cases), low-intermediate (32%), high-intermediate (20.8%), and high (11.2%), with complete response (CR) rates in the four groups being 60%, 35%, 23%, and 21%, respectively. Ten-year overall survival rates for the risk groups were as follows: low, 73.6%; low-intermediate, 45.2%; high-intermediate, 53.5%; and high, 0% (P < .001). When the International Index was included in a multivariate analysis, along with the main initial variables, International Index (P < .001) and sex (male, worse) (P = .038) were the only parameters related to survival. When response to therapy was also included, achievement of CR (P < .0001) and International Index (P < .001) were the most important factors. In patients who achieved a CR, the International Index was the only parameter related to survival (P = .051). The results were the same when the International Index was applied to the subset of 107 patients with follicular lymphoma. CONCLUSION In this study, the International Index has been found to be an important prognostic tool in low-grade lymphomas. Such an index could be used to predict prognosis not only in aggressive, but also in low-grade lymphomas.

Abstract
Transient appearance of anti-erythrocyte autoantibodies was demonstrated in two women in the first stages of Rh alloimmunization. Any mimicking antibodies, or concurrent autoimmune haemolytic anaemia could be reasonably discarded in both patients. These facts are discussed on the basis of polyclonal activation followed by clonal selection driven by the antigen, as a mechanism of the humoral immune response. Investigation of such cases seems of great interest in subjects with recent alloimmunization in order to assess the incidence of this phenomenon and the antigen systems involved.

Abstract
PURPOSE To analyse the frequency and the main clinico-haematologic characteristics of the patients with Ph'-positive chronic myelogenous leukaemia (CML) with long survival. MATERIAL AND METHODS Of a series of 100 patients with CML diagnosed in the chronic phase and treated in the conventional way at the "Farreras Valentí" School of Haematology between 1969 and 1982, and followed-up for at least 10 years, those surviving more that 8-10 years since the diagnosis were considered eligible for this study. Their clinico-haematological characteristics at diagnosis were compared to those of the remaining patients by means of the Student's t and Mann-Whitney's U tests, plus chi square with the Yates correction. The actuarial survival in the series was assessed according to the Kaplan and Meier method. The Sokal prognostic index was calculated in the longest survivors. RESULTS The median survival of the series was 45 months (range: 4-171). Ninety-one patients died, 2 are alive in chronic phase and in 7 others the follow-up has been lost in the chronic phase. Eight patients survived more than 10 years and 14 more than eight years. Of these, six were men and eight women, 10 were under 50 years of age, one-half lacked splenomegaly at diagnosis and only 2 had Ph' chromosome mosaicism. According to the Sokal prognostic index, six of these patients were in the low-risk group, four were of intermediate risk, and four others were in the high-risk group. None of them had aplasia due to busulphan during the follow-up. When comparing the initial features of the patients surviving 8-10 years with those of the remainders, only the presence of a lower percentage of blast-cells (p = 0.03) and a lower number of blasts in peripheral blood (p = 0.01) in the former achieved statistically significant difference. CONCLUSIONS These findings confirm the difficulty in identifying the CML patients with expected long survival at diagnosis. High numbers of cases must be analysed in order to attain definite conclusions in this regard.

Abstract
PURPOSE To evaluate in a sequential fashion the activity of the leukocyte alkaline phosphatase (LAP) in the chronic phase and the blastic crisis of chronic myelogenous leukaemia (CML). MATERIAL AND METHODS This study is comprised of 43 patients diagnosed of CML according to standard criteria. The initial LAP scores were compared with those recorded in the blastic crisis, using cytochemical methods. The statistical analysis was performed with Student's test and chi-square. RESULTS The LAP activity at diagnosis was low in 40 of the 43 cases (93%), the score being 0 in 20 instances. In the blastic crisis low scores were found in 27 patients (63%), while LAP activity appeared normal or increased in 16 others (37%). When the LAP scores of the two phases of the disease were compared the differences were found statistically significant (p less than 0.0001 and p less than 0.0007, respectively). CONCLUSIONS These results confirm that the onset of the blastic crisis of CML is often accompanied by an increase of the LAP activity, although this last persists low in the majority of the patients.

Abstract
A 52 year old male presenting chronic myeloid leukemia (CML) Philadelphia chromosome positive (Ph) four years after the diagnosis of a non Hodgkin's lymphoma is described. The patient had received high total doses of alkylating drugs (cyclophosphamide and chlorambucil) as part of chemotherapy treatment for a diffuse mixed lymphoma. At four years of diagnosis of the lymphoma the appearance of hepatosplenomegaly, leukocytosis with myeloma and basophilia and thrombocytosis were observed. These alterations augmented progressively until a cytogenetic study of the bone marrow two years late established the diagnosis of CML upon demonstrating the presence of the Ph chromosome with no other karyotypic anomalies being observed. The explorations carried out at that time confirmed that the lymphoma continued to be in remission. The CML initially responded to treatment with busulphan. However, following a year and a half the disease evolved to a phase of acceleration and the patient died a few weeks later due to pneumonia with no signs indicative of lymphoma activity having been detected since the diagnosis of the CML.
