Abstract Aggressive Non-Hodgkin lymphoma (NHL) is heterogeneous group with respect to clinical, histopatological and evaluative features. The International Prognostic Index (IPI) has provided a widely accepted prognostic set of criteria to design therapy. However, IPI dose not determine whether routine phenotypic features, beside IPI, may influence survival. We evaluate the prognostic significance of Bcl-2 and Ki67 protein expression in relation to clinical presentation and outcome. In the period 1989–2002,two hundred eleven patients with newly diagnosed aggressive NHL were recorded in our Department. In this study we included patients with available biopsy sample. Protein expression was analyzed on paraffin embedded tumor tissue by imunohistochemistry in relation to clinical factor and outcome. The expression of more than 20% of neoplastic cell was considered positive for bcl-2, and more than 60% for Ki-67. Comparison was made by x2 test. Survival curves were considered by Kaplan-Meyer method and compared by the long-rank test. Sixty seven patients were recorded and their characteristic were: median age 53 years, stage III and IV, 67%; present B symptoms 44%,; bone marrow infiltration 29%, elevated LDH 58%, performas status more then 1– 26%; extra nodal sites more than 2 –34%. All 62 patients received antracyclin based combination chemotherapy, 72% CHOP regiment. Overall survival was 52% with a follow up 6–183 months. Bcl-2 expression was observed in 35,5% (22pts) and Ki67 positivity over 60% in 20 pts (30%). Overall survival was influenced by bcl-2 and Kli67 expression. Bcl-2 positive cases were significantly associated with lower overall survival (20% vs. 58%; p<0.01). Overall survuval was significantly worse in patients with Ki67 positivity over 60% (27% vs. 49%; p<0.05) Bcl-2 and Ki67 monoclonal antibody immunostaging appears to be a simple and reproducible method of determining biological potential of tumor cells and provides useful prognostic information in patients with aggressive NHL.

The Impact

Abstract The tumor microenvironment plays an important role in the biologic behavior of follicular lymphoma (FL), but the specific cell subsets involved in this regulation are unknown. To determine the impact of FOXP3-positive regulatory T cells (Tregs) in the progression and outcome of FL patients, we examined samples from 97 patients at diagnosis and 37 at first relapse with an anti-FOXP3 monoclonal antibody. Tregs were quantified using computerized image analysis. The median overall survival (OS) of the series was 9.9 years, and the FL International Prognostic Index (FLIPI) was prognostically significant. The median Treg percentage at diagnosis was 10.5%. Overall, 49 patients had more than 10% Tregs, 30 between 5% to 10%, and 19 less than 5%, with a 5-year OS of 80%, 74%, and 50%, respectively (P = .001). Patients with very low numbers of Tregs (< 5%) presented more frequently with refractory disease (P = .007). The prognostic significance of Treg numbers was independent of the FLIPI. Seven transformed diffuse large B-cell lymphomas (DLBCLs) had lower Treg percentages (mean: 3.3%) than FL grades 1,2 (mean: 12.1%) or 3 (mean: 9%) (P < .02). In conclusion, high Treg numbers predict improved survival of FL patients, while a marked reduction in Tregs is observed on transformation to DLBCL.

Preclinical and clinical evidence suggest a potential advantage for infusional therapy in lymphoma. Sixty-two analyzable patients with predominantly intermediate-grade non-Hodgkin lymphoma received cyclophosphamide (200 mg/m2 per day), doxorubicin (12.5 mg/m2 per day), and etoposide (60 mg/m2per day) (CDE) by continuous intravenous infusion for 4 days (96 hours) every 3 weeks for a maximum of 8 cycles. By the age-adjusted International Prognostic Index (IPI), 42% were at high risk and 58% were at high-intermediate risk. Complete response (CR) occurred in 30 (48%) patients (95% confidence interval [CI], 35%, 64%), and partial response occurred in 16 (26%) patients, yielding an overall response rate of 74% (95% CI, 62%, 84%). Failure-free survival (FFS) rates at 1 and 2 years were 55% (95% CI, 43%, 67%) and 50% (95% CI, 38%, 62%), respectively. When comparing the outcome for 62 patients receiving infusional CDE with historical data derived from 927 IPI-matched lymphoma patients using a Cox proportional hazards model, there was a nonsignificant trend favoring CDE in FFS (P = .12) and overall survival (P = .09). Severe or life-threatening toxicity included neutropenia (68%), anemia (57%), thrombocytopenia (44%), and infection (24%). Two patients (3%) died of treatment-related infectious complications. The primary end point of improving 1-year FFS from 55% to 70% was not achieved with infusional CDE given as initial therapy in patients with poor-risk intermediate-grade lymphoma. It is unlikely that infusional therapy as used in this study produces a 25% or greater relative improvement in FFS compared with standard therapy.

Abstract In this retrospective study we described the response and toxicity of a modified Magrath IVAC (mIVAC) regimen in 25 patients with refractory/relapsed aggressive non-Hodgkin lymphoma (NHL). The mIVAC consisted of ifosfamide 1,500mg/m2 (one-hour infusion beginning at 9:00; D1 to D5), mesna 300mg/m2 (bolus at hours 9:00, 13:00, 17:00; D1 to D5), citarabine 2,000 mg/m2 (two one-hour infusions beginning at 8:00 and 16:00; D1 and D2) and etoposide 60 mg/m2 (one-hour infusion beginning at 10:00; D1 to D5). Treatment was repeated every four weeks for a maximum of six cycles. Patients who achieved partial remission or complete remission after at least three courses were offered autologous stem cell transplantation (ASCT), if eligible. The median age was 37 years (range 18 to 59 years). Twenty-two (88%) patients had diffuse large B-cell lymphoma, fourteen (56%) had relapsed disease and 10 (40%) were considered high-intermediate and high risk by age-adjusted International Prognostic Index. The overall response rate was 68% (95% CI: 46%–90%). A total of 64 cycles were given, with a median of three courses per patient. Grade 3/4 neutropenia was observed after 85,6% of the courses, and grade 3/4 thrombocytopenia was observed after 87,5% of the courses. Grade 3/4 neutropenic fever occurred after 28% of the courses. Non-hematologic toxic effects were rare, predominantly grade 1/2. No toxic deaths were observed. Fifteen (88%) of the 17 responding patients underwent ASCT. With a median follow-up of 14 months, the median overall survival time for mIVAC sensitive patients was 16 months. This regimen may be feasible for patient with relapsed and refractory aggressive NHL in countries with inadequate numbers of hospital beds.

Purpose Mantle-cell lymphoma (MCL) has a variable natural history but is incurable with current therapies. MicroRNAs (miRs) are useful in prognostic assessment of cancer. We determined an miR signature defining aggressiveness in B-cell non-Hodgkin lymphomas (NHL) and assessed whether this signature aids in MCL prognosis. Methods We assessed miR expression in a training set of 43 NHL cases. The miR signature was validated in 44 additional cases and examined on a training set of 119 MCL cases from four institutions in Canada. miRs significantly associated with overall survival were examined in an independent cohort of 114 MCL cases to determine association with patient outcome. miR expression was combined with current clinical prognostic factors to develop an enhanced prognostic model in patients with MCL. Results Fourteen miRs were differentially expressed between aggressive and indolent NHL; 11 of 14 were validated in an independent set of NHL (excluding MCL). miR-127-3p and miR-615-3p were significantly associated with overall survival in the MCL training set. Their expression was validated in an independent MCL patient set. In comparison with Ki-67, expression of these miRs was more significantly associated with overall survival among patients with MCL. miR-127-3p was combined with Ki-67 to create a new prognostic model for MCL. A similar model was created with miR-615-3p and Mantle Cell Lymphoma International Prognostic Index scores. Conclusion Eleven miRs are differentially expressed between aggressive and indolent NHL. Two novel miRs were associated with overall survival in MCL and were combined with clinical prognostic models to generate novel prognostic data for patients with MCL.

Background. Bone marrow is the mostfrequent metastatic site in follicular lymphoma, 40-70 % cases. It’s unfovourable prognostic role is stated in the index FLIPI-2 (Follicular Lymphoma International Prognostic Index-2). Objective. To study both prognostic role of bone marrow involvement and it’s relation to erythropoiesis peculiarities in follicular lymphoma was the purpose of this research. Materials and methods. Histological study was performed in 269 follicular lymphoma patients. Erythropoiesis peculiarities were studied in that patients according to standard myelogram analysis. Results. Bone marrow involvement was noted according to trephine biopsy section staining in 37,9 % of follicular lymphoma case (102 from 269). Bone marrow involvement did not influenced the prognosis (overall survival) in all period of observation (p = 0,18). Longterm survival (more than 48 months) was negatively influenced by bone marrow involvement (p = 0,04). Intertrabecular pattern of follicular lymphoma growth in bone marrow was negative prognostic factor (p = 0,02). We noted negative correlation between bone marrow involvement and the elevation of orthochromic normoblasts in bone marrow of patients with follicular lymphoma. In cause of bone marrow such elevation was noted in 67 %, and in the absense of involvement - in 78 % (p = 0,043). Elevation of orthochromic normoblasts did not influenced the overall survival of follicular lymphoma patients (p = 0,89). Conclusion. Bone marrow involvement in follicular lymphoma plays prognostically unfavourable role in long-time observation periods (later than 48 months). The most unfavourable are the intertrabecular patchy lesions. Involvement of bone marrow is in opposite relations to elevation of orthochromic normoblast, but the latter sign is of no prognostic significance.

Lymphoma is the fifth most common type of cancer in the United States, with 74,490 new cases estimated in 2009. Approximately 15% of patients with lymphoma have Hodgkin lymphoma; the remainder have one of the non-Hodgkin lymphomas. The incidence of non-Hodgkin lymphoma has increased steadily over recent decades. This chapter reviews the epidemiology, classification, clinical features, pathology, diagnostic evaluation, staging and prognosis, and treatment of Hodgkin and non-Hodgkin lymphoma. Other topics discussed include the acute and chronic effects of therapy for Hodgkin disease, as well as the subtypes of non-Hodgkin lymphomas, including indolent B cell lymphoma, follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, marginal-zone lymphoma, diffuse large B cell lymphoma (DLBCL), primary central nervous system lymphoma (PCNSL), Burkitt lymphoma, and HIV-related non-Hodgkin lymphoma. Figures illustrate the cellular appearance of Hodgkin lymphoma subtypes and DLBCL, diagnosis of DLBCL subtypes by gene expression, computed tomography and plain chest film in primary mediastinal cell lymphoma, MRI of the brain in PCNSL, and gene expression and gene expression predictors of survival among patients with DLBCL treated with rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine [Oncovin], and prednisone (R-CHOP). Tables describe the Ann Arbor classification and the Cotswold modification for staging of lymphoma; the International Prognostic Score for advanced Hodgkin lymphoma; the World Health Organization classification of hematopoietic neoplasms; chromosomal translocations in non-Hodgkin lymphoma; the Eastern Cooperative Oncology Group performance scale; the International Prognostic Index for aggressive non-Hodgkin lymphoma; and the Follicular Lymphoma International Prognostic Index.

Abstract The purpose of the study was to evaluate response, duration of response, and toxicity of fludarabine (F), mitoxantrone (M), and dexamethason (D) (FMD) in patients (pts) with relapsed or refractory low-grade non-Hodgkin lymphoma (LGNHL). 26 pts with advanced relapsed/refractory LGNHL exposed to previous chemotherapy (CHT) received 3–6 monthly cycles of FMD. The median age was 60 years (range 34–73), included 13 male (50%) and 13 female (50 %). The regimen consisted of F (25 mg/m2 i.v., day 1–3), M (10 mg/m2 i.v., day 1) and D (20 mg p.o., day 1–5). Parameters analyzed included response, toxicity and infection rates, number of previous CHT lines, performance status (ECOG), Ann Arbor scale, LDH, International Prognostic Index score, freedom from progression (FFP) and overall survival (OS). In total 78 cycles of FMD was administered. This induced 25% complete and 37,5% partial response, with a total response rate of 62,5%. After 14 months of the median follow-up of the pts remaining alive, median FFP was 11 months and median OS has not been achieved yet. Out of 78 administered cycles 16 (20%) were associated with toxicity, including 8 (10%) severe infections despite prophylaxis and 6 (8%) grade III/IV neutropenias. In addition, one case of grade III/IV thrombocytopenia and acute noninflammatory renal dysfunction were observed. Toxicity rate was not correlated with the number of previous CHT lines or ECOG, but IPI >2 was significant factor predictive for FMD-related toxicity (p=.037). Shorter OS was observed for the pts with ECOG>1 (p=.049), IPI>2 (p=.005) and FMD-related toxicity (p=.036). FMD is an active regimen for relapsed and refractory LGNHL. Toxicity rate is substantial and seems to predict survival.
