RESUMEN

BACKGROUND: Many patients with aggressive B-cell lymphomas and high clinical risk score still die of lymphoma after conventional R-CHOP chemoimmunotherapy. We hypothesized that intensified chemoimmunotherapy including systemic central nervous system (CNS) prophylaxis improves outcome and reduces the incidence of CNS-related events. PATIENTS AND METHODS: Inclusion criteria were age 18-65 years, primary diffuse large B-cell lymphoma or grade III follicular lymphoma without clinical signs of CNS disease and negative cerebrospinal fluid cytology, age-adjusted International Prognostic Index 2-3 and WHO performance score 0-3. Treatment consisted of six courses of R-CHOEP-14 followed by a course of high-dose cytarabine and a course of high-dose methotrexate. Primary end point was failure-free survival (FFS) at 3 years. RESULTS: A total of 156 eligible patients with a median age of 54 years (range 20-64) were included. Three toxic deaths were observed. Three-year overall survival (OS) and FFS rates (median observation time 52 months for survivors) were 81% and 65%, respectively. Seven patients experienced CNS relapse, all within 6 months. CONCLUSIONS: The results are promising with favorable 3-year OS and FFS rates, a low toxic death rate and a lower than expected number of CNS events. CNS progression might be further reduced by earlier CNS prophylaxis. CinicalTrials.gov. identifier NCT01502982.

RESUMEN

BACKGROUND: Testicular lymphoma is a rare malignancy affecting mainly elderly men, the majority representing diffuse large B-cell lymphoma (DLBCL). Its relapse rate is higher than that of nodal DLBCL, often affecting the central nervous system (CNS) with dismal prognosis. PATIENTS AND METHODS: We searched for patients with testicular DLBCL (T-DLBCL) involvement from the pathology databases of Southern Finland University Hospitals and the Danish Lymphoma Registry. Clinical information was collected, and outcomes between treatment modalities were evaluated. Progression-free survival (PFS), disease-specific survival (DSS) and overall survival (OS) were assessed using Kaplan-Meier and Cox proportional hazards methods. RESULTS: We identified 235 patients; of whom, 192 were treated with curative anthracycline-based chemotherapy. Full survival data were available for 189 patients. In univariate analysis, intravenous CNS-directed chemotherapy, and irradiation or orchiectomy of the contralateral testis translated into favourable PFS, DSS and OS, particularly among the elderly patients (each p ≤ 0.023). Intrathecal chemotherapy had no impact outcome. In multivariate analyses, the advantage of intravenous CNS-directed chemotherapy (hazard ration [HR] for OS, 0.419; 95% confidence interval [CI], 0.256-0.686; p = 0.001) and prophylactic treatment of contralateral testis (HR for OS, 0.514; 95% CI, 0.338-0.782; p = 0.002) was maintained. Rituximab improved survival only among high-risk patients (International Prognostic Index≥3, p = 0.019). The cumulative risk of CNS progression was 8.4% and did not differ between treatment modalities. CONCLUSION: The results support the use of CNS-directed chemotherapy and prophylactic treatment of the contralateral testis in patients with T-DLBCL involvement. Survival benefit appears resulting from better control of systemic disease rather than prevention of CNS progression.

RESUMEN

Non-germinal center (non-GC) phenotype is an adverse prognostic factor in chemotherapy (CT)-treated diffuse large B-cell lymphoma (DLBCL) patients. To determine how high-dose therapy (HDT) supported with auto-SCT as first line therapy influences GC-associated outcome in young high-risk DLBCL patients GC and non-GC phenotypes were determined immunohistochemically from 63 patients. Of these, 29 primary high-risk DLBCL patients were treated with auto-SCT, whereas 34 CT-treated patients served as a control group. Consistent with previous studies, non-GC phenotype was associated with adverse outcome in CT-treated high-risk patients. In contrast, immunohistochemical classification by cell of origin did not associate with survival after auto-SCT. When the impact of treatment on the predictive value of cell of origin was analyzed, the non-GC patients, who received HDT, had a better failure-free survival (FFS) and overall survival (OS) than the patients treated with CT alone. In multivariate analyses, both age-adjusted International Prognostic Index (aaIPI) and treatment were independent prognostic factors for FFS and OS. For the patients with GC phenotype, the influence of auto-SCT on survival was not significant. The data imply that auto-SCT can overcome the adverse prognostic impact of the non-GC phenotype in patients with high-risk DLBCL and warrant additional prospective studies.

RESUMEN

The introduction of the anti-CD20 antibody rituximab in combination with chemotherapy (R-chemo) has improved the prognosis of patients with follicular lymphoma (FL). During the last decade, the addition of a maintenance treatment with rituximab (MR) after R-chemo has been tested with the hope of further improving the outcome of these patients. Using 2 independent population-based cohorts, we investigated the effect of up-front MR on time related end points as well as the risk of histological transformation (HT). FL patients were included if they: (1) completed first-line induction treatment with R-chemo, (2) were alive after induction treatment and eligible for MR, and (3) had no evidence of HT at this time point. The training cohort consisted of 733 Danish patients of whom 364 were consolidated with MR; 369 were not. Patients receiving MR more often had advanced clinical stage (90% vs 78%), high Follicular Lymphoma International Prognostic Index (FLIPI) score (64% vs 55%), and bone marrow infiltration (49% vs 40%). Those consolidated with MR had an improved 5-year overall survival (OS; 89% vs 81%; P = .001) and progression-free survival (PFS; 72% vs 60%; P < .001). In the training cohort, MR was associated with a reduction of HT risk (P = .049). Analyses of an independent validation cohort of 190 Finnish patients confirmed the favorable impact of MR on 5-year OS (89% vs 81%; P = .046) and PFS (70% vs 57%; P = .005) but did not find a reduced risk of HT. The present population-based data suggest that the outcome of patients with FL has improved after consolidation of R-chemo with MR.

RESUMEN

Many if not most tissues need a controlled number of stem cells to maintain normal function. Cancer can be seen as a process of disturbed tissue homeostasis, in which too many cells have or acquire too primitive identity. Here we measured how oncogenes and tumour suppressors affect the differentiation capacity, proportion and characteristics of progenitor cells in a model tissue. Neural progenitor cells (NPCs) were exposed to human papilloma virus E6, E7 or E6/E7 oncogenes, which degrade tumour suppressors p53 and pRb family members, respectively. E6/E7-expressing or p53-/- NPCs were able to differentiate, but simultaneously retained high capacity for self-renewal, proliferation, ability to remain multipotent in conditions promoting differentiation and showed delayed cell cycle exit. These functions were mediated through p53 and pRb family, and involved MEK-ERK signalling. Decreased amount of p53 increased self-renewal and proliferation, whereas pRb affected only proliferation. Our results suggest that the oncogenes increase whereas p53 and pRb family tumour suppressors decrease the number and proportion of progenitor cells. These findings provide one explanation how oncogenes and tumour suppressors control tissue homeostasis and highlight their importance in stem cell self- renewal, linked both to cancer and life-long tissue turnover.

RESUMEN

c-Jun activation by mitogen-activated protein kinases has been implicated in various cellular signal responses. We investigated how JNK and c-Jun contribute to neuronal differentiation, cell survival, and apoptosis. In differentiated PC12 cells, JNK signaling can induce apoptosis and c-Jun mediates this response. In contrast, we show that in PC12 cells that are not yet differentiated, the AP-1 family member ATF-2 and not c-Jun acts as an executor of apoptosis. In this context c-Jun expression protects against apoptosis and triggers neurite formation. Thus, c-Jun has opposite functions before and after neuronal differentiation. These findings suggest a model in which the balance between ATF-2 and Jun activity in PC12 cells governs the choice between differentiation towards a neuronal fate and an apoptotic program. Further analysis of c-Jun mutants showed that the differentiation response requires functional dimerization and DNA-binding domains and that it is stimulated by phosphorylation in the transactivation domain. In contrast, c-Jun mutants incompetent for DNA binding or dimerization and also mutants lacking JNK binding and phosphorylation sites that cannot elicit neuronal differentiation efficiently protect PC12 cells from apoptosis. Hence, the protective role of c-Jun appears to be mediated by an unconventional mechanism that is separable from its function as a classical AP-1 transcription factor.

RESUMEN

A cell surface proteoglycan, syndecan-1, has been shown to participate in the maintenance of the epithelial cell morphology. A point mutated activated c-Ha-ras gene under the control of the glucocorticoid inducible MMTV-LTR promoter was transfected into the mouse mammary epithelial cell line, NOG-8. The NOG-8 ras cells were used to study changes in syndecan-1 expression during epithelial transformation. NOG-8 ras cells, when induced to express Ha-ras, transformed and formed foci in monolayer cultures and colonies in suspension cultures. Expression of syndecan-1 at the cell surface was markedly reduced in cells showing the transformed phenotype. The accumulation of newly synthesized core protein of syndecan-1 was suppressed in these cells, whereas mRNA levels remained unchanged. This novel finding indicates that syndecan-1 expression is translationally suppressed in the Ha-ras-transformed epithelial cells. Hence, syndecan-1 loss during epithelial transformation could take place without altering syndecan gene transcription and, on the other hand, could be one of the critical events involved in malignant transformation.

RESUMEN

Effect of alternative splicing (AS) on diffuse large B-cell lymphoma (DLBCL) pathogenesis and survival has not been systematically addressed. Here, we compared differentially expressed genes and exons in association with survival after chemoimmunotherapy, and between germinal center B-cell like (GCB) and activated B-cell like (ABC) DLBCLs. Genome-wide exon array-based screen was performed from samples of 38 clinically high-risk patients who were treated in a Nordic phase II study with dose-dense chemoimmunotherapy and central nervous system prophylaxis. The exon expression profile separated the patients according to molecular subgroups and survival better than the gene expression profile. Pathway analyses revealed enrichment of AS genes in inflammation and adhesion-related processes, and in signal transduction, such as phosphatidylinositol signaling system and adenosine triphosphate binding cassette transporters. Altogether, 49% of AS-related exons were protein coding, and domain prediction showed 28% of such exons to include a functional domain, such as transmembrane helix domain or phosphorylation sites. Validation in an independent cohort of 92 DLBCL samples subjected to RNA-sequencing confirmed differential exon usage of selected genes and association of AS with molecular subtypes and survival. The results indicate that AS events are able to discriminate GCB and ABC DLBCLs and have prognostic impact in DLBCL.

RESUMEN

Limited experience is available on the feasibility and efficacy of autologous stem cell transplantation (ASCT) in elderly patients with non-Hodgkin's lymphoma (NHL). In 1994-2004 altogether 88 NHL patients > 60 years old received ASCT in six Finnish transplant centres. There were 57 male and 31 female patients with a median age of 63 years (range 60-70 years); 17 patients were>65 years. The histology included diffuse large B cell (n = 29), mantle cell (n = 27), follicular (n = 15), peripheral T cell (n = 12) and other (n = 5). Disease status at ASCT was I complete remission/partial remission (CR/PR) in 53 patients, II CR/PR in 30 patients and other in five patients. The conditioning regimens included BEAC (n = 49), BEAM (n = 34), TBI-CY (n = 4) and other (n = 1). Eighty-four patients received PB grafts. The medians to reach neutrophils > 0.5 and platelets > 20 were 10 and 14 days, respectively. The early treatment-related mortality (TRM) (<100 days) was 11%. With a median follow-up of 21 months for all patients, 45 patients (51%) are alive. A relapse or progression after ASCT has been observed in 32 patients (36%). ASCT is feasible in selected elderly patients with NHL, but the early TRM seems to be higher than in younger patients.

RESUMEN

PURPOSE: Syndecan-1 is a multifunctional transmembrane heparan sulfate proteoglycan present on a variety of cell types that mediates basic fibroblast growth factor (bFGF) and other growth factor binding. High serum syndecan-1 (S-syndecan-1) ectodomain levels have been found to be associated with poor outcome in lung cancer and myeloma, but little is known about the effect of cancer treatment on S-syndecan-1 levels. We studied S-syndecan-1 levels longitudinally in a series of patients diagnosed with locoregional squamous cell larynx or hypopharynx carcinoma (n=44) and who we treated with surgery and/or radiation therapy. METHODS: S-syndecan-1 and S-bFGF levels were measured with ELISA prior to, during, and following primary treatment of patients. Syndecan-1 expression was assessed from formalin-fixed and paraffin-embedded tumour samples using immunohistochemistry. RESULTS: S-syndecan-1 levels tended to correlate positively with S-bFGF levels, and the pretreatment levels decreased from a median value of 75 to 58 ng/ml 3 months following treatment (P<0.0001). Patients treated with radiation therapy had a transient increase in S-syndecan-1 during the course of radiation therapy. Patients whose S-syndecan-1 decreased >or=10% from the pretreatment level had more favourable survival than those whose levels remained stable or increased (P=0.0069). Recurred cancer was associated with elevated S-syndecan-1 as compared to the levels measured 3 months following completion of primary therapy. CONCLUSIONS: These findings suggest that a part of S-syndecan-1 originates from the cancerous tissue, and that S-syndecan-1 levels generally decrease following successful cancer treatment.

RESUMEN

c-Jun/AP-1 activation has been implicated in various, often opposing cellular responses. For example, although there is considerable evidence that c-Jun activation can be a positive step in the events leading a cell towards apoptosis, there are also many reports stating the opposite: that under certain circumstances c-Jun can inhibit apoptosis and promote proliferation or differentiation instead - and that these responses are important for normal mammalian development. It is clear that the effects of c-Jun on cellular responses depend strongly on the cell type and the context of other regulatory influences that the cell is receiving. This review focuses on recent developments in understanding how activation of JNK and c-Jun contributes to different cellular responses.

RESUMEN

Two members of the heat shock transcription factor family, HSF1 and HSF2, have been identified as activators of mammalian heat shock gene expression. HSF1 acts as a classical stress-responsive factor, whereas HSF2 might play a role in embryogenesis, since it is active during pre- and post-implantation periods up to 15.5 days of mouse embryonic development. In this study, we analyzed HSF1 and HSF2 expression and activation during mouse heart formation. Our results show an abundant expression of HSF1 throughout heart development. In contrast, expression of the alternatively spliced HSF2-alpha and HSF2-beta, and an additional higher molecular weight isoform is strongly upregulated in the developing mouse heart at E11.5-12.5, a stage after which tubular heart has looped and chambers formed, and the myocardial walls are maturating and the valves differentiating. At the same developmental stage, HSF2 DNA-binding activity is transiently induced, whereas the weak HSE-binding activity, which is detected throughout heart development, consists primarily of HSF1. Interestingly, heat shock gene expression shows no temporal or spatial correlation with HSF2 expression and activation. Taken together, our results indicate that HSF2 activation is associated with specific stages of heart formation but is not involved in the regulation of inducible heat shock gene expression.

RESUMEN

Limited experience is available on the feasibility and efficacy of high-dose therapy (HDT) supported by autologous stem cell transplantation (ASCT) in patients with peripheral T-cell lymphoma (PTCL). Therefore, a nation-wide survey was conducted in adult patients transplanted for PTCL in Finland during 1990-2001. After histopathology review, 37 patients were identified. The median age was 46 years (16-68) at the time of ASCT. Histology included PTCL not otherwise specified in 14 patients, anaplastic large cell lymphoma (ALCL) in 14 patients, and other in nine patients. Disease status at the time of ASCT was CR/PR1 in 18 patients; CR/PR2 in 14 patients, and other in five patients. HDT consisted of either BEAC (N=22) or BEAM (N=15), supported by blood stem cells in 34 patients (92%). Early transplant-related mortality was 11%. With a median follow-up of 24 months from HDT, 16 patients (43%) have relapsed or progressed. The estimated 5-year overall survival (OS) was 54%. Patients with ALCL had superior OS when compared with other subtypes (85 vs 35%, P=0.007). OS at 5 years was 63% in patients transplanted in CR/PR1 vs 45% in those transplanted in other disease status (P=NS). Prospective studies are needed to define the role of ASCT in this lymphoma type.

RESUMEN

Tissue irritation after intramuscular injections of 4 nonsteroidal anti-inflammatory agents was studied in 5 lactating cows. Preparations containing phenylbutazone, flunixin, metamizole (dipyrone) and ketoprofen were investigated; physiological saline was used as a control substance. Tissue reactions at the injection sites were examined by palpation and by determining serum creatine kinase. A kinetic method based on creatine kinase released from the injured muscle tissue was used, which allowed estimation of the amount of damaged muscle. The metamizole preparation clearly provoked signs of pain all the cows. After flunixin and phenylbutazone injections slight reactions were observed, and ketoprofen and saline did not cause any clinical signs. Some palpatory findings after injections were found for all the preparations except saline. Based on serum creatine kinase, the 2 most irritating preparations were the ones containing flunixin and phenylbutazone. After injections of these 2 substances, the estimated amount of damaged muscle was about 80 grams. The statistical difference between flunixin and phenylbutazone and the other 2 preparations was significant. Physiological saline had no effect on serum creatine kinase. For preparations containing phenylbutazone and flunixin, intravenous administration is recommended.

RESUMEN

Data on the incidence and causes of late (>100 d) non-relapse mortality (NRM) in autologous stem cell transplant (ASCT) recipients is limited. We have analysed NRM in a cohort of 1,482 adult patients who received ASCT in 1990-2003 in six Finnish transplant centres. The most common diagnoses included non-Hodgkin's lymphoma (NHL) (n = 542), multiple myeloma (MM) (n = 528), breast cancer (n = 132); Hodgkin's lymphoma (HL) (n = 86) and chronic lymphocytic leukaemia (CLL) (n = 63). Until September 2005, 646 patients (44%) have died. Late NRM was observed in 68 patients (4.6% of ASCT recipients; 11% of all deaths). There were 38 males and 30 females with a median age of 58 yr (20-69) at the time of ASCT. The median time to NRM was 27 months from ASCT (3-112). The risk of NRM was highest in patients with CLL (9.5%) and those with HL (8.1%) followed by MM and NHL (4.9% and 4.8%, respectively). The risk of late NRM was comparable in patients who received total body irradiation (TBI) and those who received chemotherapy-only regimens (6.7% vs. 4.3%). Another malignancy was the most common cause of late NRM (24 patients, 35% of late NRM). Twelve patients (0.8% of ASCT recipients) have died due to secondary haematological malignancy. Altogether 22 patients (32% of late NRM) died from infectious causes. Malignancies and late infections are important causes of NRM after ASCT. These facts point out the importance of prolonged follow-up in ASCT recipients.

RESUMEN

OBJECTIVES: To evaluate early (<100 d) treatment-related mortality (TRM) in autologous stem cell transplant (ASCT) recipients. PATIENTS: Altogether 1482 adult patients received ASCT in six Finnish centres 1990-2003. The most common diagnoses were non-Hodgkin's lymphoma (NHL) (n = 542), multiple myeloma (MM) (n = 528), breast cancer (BC) (n = 132), Hodgkin's lymphoma (n = 86) and chronic lymphocytic leukaemia (CLL) (n = 63). RESULTS: Forty-two patients (2.8%) died from treatment-related reasons <100 d from ASCT. The median time to death was 38 d from ASCT (0-99). The risk of TRM varied according to the diagnoses. The highest risk was observed in patients with AL amyloidosis (24%) followed by NHL (4.4%) and MM (1.9%). No early TRM was observed in patients transplanted for BC or CLL. Infections were the cause of death in 16 patients (fungal 7, bacterial 6, viral 3). Organ toxicity was responsible for early death in 26 patients (heart 9, lungs 7, other 10). CONCLUSIONS: This nation-wide survey indicated a low early TRM in ASCT recipients in general, but higher risks in patients with AL amyloidosis or NHL. In addition to patient selection, also optimization of transplant procedure may be needed in these patient groups to reduce early TRM.

RESUMEN

PURPOSE: Serum postoperative matrix metalloproteinase 2 (MMP-2) level is a predictor of outcome in node positive breast cancer and can be used to stratify patients into low and high risk groups. Our aim was to determine how clodronate treatment influences MMP-2 associated clinical outcome. PATIENTS AND METHODS: Women with primary node-positive breast cancer were randomized to control group or to receive oral clodronate for 3 years. Adjuvant chemo- or endocrine therapy was given to all patients. The follow-up time for all patients was 5 years. MMP-2 and MMP-9 levels were quantitatively measured from the serum of 252 patients before and after 1 year clodronate treatment using enzyme-linked immunoassays. RESULTS: In clodronate-treated patients, postoperative MMP-2 levels did not predict 5-year disease-free survival or overall survival (DFS, in low MMP-2 group (<5.32 ng/ml, median) 53% versus in high MMP-2 group (>median) 63%, p=NS; OS, 68% versus 63%, p=NS). When the patients were grouped according to serum MMP-2 levels, survival rates among patients with low MMP-levels were better in control than clodronate treated patients (DFS, 82% versus 53%, p = 0.003; OS, 91% versus 68%, p=0.014). Among patients with high serum MMP-2 levels, no significant difference in DFS or OS was found between control and clodronate groups. In multivariate analysis of low risk patients, independent predictors for DFS were treatment, age, nodal and PgR status, and those for OS treatment together with nodal and ER status. During 12 months follow-up, MMP-2 levels increased significantly more in clodonate receiving patients than in controls (p = 0.002). In comparison, when the patients were grouped according to MMP-9 levels, clodronate also impaired DFS among patients with low MMP-9 levels (82% versus 53%, p = 0.02), but no influence on OS was observed (83% versus 70%, p = 0.09). CONCLUSIONS: Clodronate interferes with the prognostic value of serum MMP-2. Clodronate has a negative impact on outcome among patients with low serum MMP-2 and MMP-9 levels, while no such influence is observed among patients with high MMP-2 and MMP-9 levels.

RESUMEN

OBJECTIVES: To analyse outcome and prognostic factors in non-Hodgkin's lymphoma (NHL) patients who progress after autologous stem cell transplantation (ASCT). PATIENTS: Altogether 115 consecutive NHL patients transplanted in 1991-2000 were studied. Histology included diffuse large B cell (n = 52), follicular (n = 26), mantle cell (n = 15), T cell (n = 16) and other subtypes (n = 6). The median time from ASCT to the progression was 7 months. Ninety-six patients (83%) received salvage treatment. RESULTS: Twenty-four patients (25%) achieved complete remission and 30 (31%) partial remission. The median overall survival was 8 months (range 0-98+) and the projected 4-year survival 21%. In multivariate analysis factors predicting treatment response after the progression included the use of rituximab (P = 0.036), histology other than diffuse large B cell (P = 0.001) and International Prognostic Index < or =2 at progression (P < 0.001). Normal lactate dehydrogenase (LDH) at progression (P = 0.002), response to salvage treatment (P < 0.001) and time from ASCT to progression > or =7 months (P = 0.022) were predictors for overall survival. CONCLUSIONS: Although the prognosis of patients who progress after ASCT is generally poor, many patients will respond to current therapies, and some may experience prolonged survival. Normal LDH at time of disease progression and longer time to progression after ASCT were the most powerful predictors for a promising outcome.
