Abstract
Aims and backgroundIn order to increase the prognostic significance of polymerase chain reaction (PCR) data it has been suggested that quantitative PCR can be used to measure tumor burden. However, this option has not yet been definitely supported or refuted in patients with follicular lymphoma (FL). We decided to evaluate whether knowledge of the quantitative level of minimal residual disease and its variations can be of use in the management of FL patients.MethodsWe used qualitative and competitive PCR to study 11 patients with refractory or relapsed FL harboring the t(14;18) translocation who underwent autologous (nine patients) or allogeneic (two patients) stem cell transplantation (SCT). Competitive PCR was performed with a multiple competitor carrying specific sequences including Bcl2/lgH MBR and mcr, and the β-globin gene.ResultsAfter a median post-SCT follow-up of 44 months (range, 12-62), overall survival was 91% and disease-free survival 82%. The quantitative PCR data showed that: 1) effective chemotherapy before SCT substantially (1-2 log) reduced the tumor burden in the bone marrow (BM); 2) the increase in rearranged DNA detected in BM was associated with disease progression and relapse; 3) a PCR-negative autograft seemed to lead to lasting molecular remission even when it was performed in patients with a low level of BM infiltration before transplant; and 4) allo-SCT made and maintained the BM PCR negative even in the presence of a greater tumor burden before SCT. Six of the nine patients having CR after SCT (four auto and two allo) are in continuous molecular remission.ConclusionsIn FL patients qualitative and quantitative PCR may provide data that can be helpful for the prognostic evaluation of tumor progression and the early detection of impending relapse by highlighting biological features such as the quality of the infused material, the tumor burden at transplant, and the behavior of tumor cells after transplant.

Abstract
Follicular lymphoma (FL) is generally considered an indolent disorder. With modern day treatments, long remissions are often achieved both in the front-line and relapsed setting. However, a subset of patients has a more aggressive course and a worse outcome. Their identification is the main purpose of modern day prognostic tools. In this review, we attempt to summarize the evidence concerning prognostic and predictive factors in FL, including (1) pre-treatment factors, from baseline clinical characteristics and imaging tests to histological grade, the microenvironment and genomic abnormalities; (2) post-treatment factors, i.e., depth of response, measured both by imaging tests and minimal residual disease; (3) factors at relapse and duration of response; and (4) prognostic factors in histological transformation. We conclude that, despite the existence of numerous tools, the availability of some of them is still limited; they generally suffer from notable downsides, and most have unproven predictive value, thus having scarce bearing on the choice of regimen at present. However, with the technological and scientific developments of the last few years, the potential for these prognostic factors is promising, particularly in combination, which will probably, in time, help guide therapeutic decisions.

Abstract
Follicular lymphoma (FL) is one of the most common types of non-Hodgkin's lymphoma. It is usually diagnosed at an advanced stage, for which many treatment options exist, however, no curative standard therapy has been identified. The outcome is highly variable with a median survival of approximately 10 years. The life expectancy of patients with FL has been extended with the use of rituximab, a monoclonal antibody targeting the CD20 antigen on FL cells, but there remains a group of patients who fail to respond to chemoimmunotherapy and die early of their disease. Transformation of FL to an aggressive histology is an important event with high morbidity and mortality. The Follicular Lymphoma International Prognostic Index has become the clinically useful prognostic tool, but gives only a rough estimate of expected outcome. There is a need for useful biomarkers for prediction of the disease course of single patients to individualize therapy, especially in the new era of chemoimmunotherapy.

Abstract
PURPOSE The prognostic value of residual BCL2/immunoglobulin heavy chain (BCL2/IgH) -positive cells in peripheral blood (PB) or bone marrow (BM) after induction treatment in follicular lymphoma (FL) is still controversial. In a prospective randomized phase III intergroup trial of 465 patients with relapsed/resistant follicular lymphoma (FL), we showed that addition of rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone induction results in increased overall and complete response rates, and that rituximab maintenance strongly improves median progression-free survival (PFS) as well as overall survival. Here, we studied whether BCL2/IgH major break point levels in PB/BM correlated with response rates/quality for the induction phase and PFS for the maintenance phase. PATIENTS AND METHODS Samples were obtained before and after induction therapy and at the end of the 2 years maintenance/observation period. BCL2/IgH major break point-positive cells were quantified by genomic quantitative polymerase chain reaction in 792 samples from 238 patients. RESULTS Pretreatment BCL2/IgH levels had no significant prognostic value for overall response or complete remission rates after induction treatment, but pretreatment positive BM results had an adverse prognostic value for PFS from first randomization (P = .023). Importantly, BCL2/IgH levels at the end of induction treatment had no prognostic value for PFS from second randomization. The highly significant improved PFS by rituximab maintenance was observed in both BCL2/IgH PB/BM-positive and -negative groups. CONCLUSION Postinduction BCL2/IgH major break point status in BM/PB is not useful for decisions on subsequent therapy for patients with relapsed/resistant FL.

Abstract
BACKGROUND Rituximab, a monoclonal anti-CD20 antibody, in combination with chemotherapy improves overall survival compared to chemotherapy alone when used for induction therapy for patients with newly diagnosed or relapsed indolent lymphoma. Randomised controlled trials have demonstrated that maintenance treatment with rituximab prolongs progression-free survival but evidence of effect on overall survival is lacking. OBJECTIVES To evaluate the effects of maintenance treatment with rituximab on overall survival in patients with follicular lymphoma. SEARCH STRATEGY We electronically searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2), PubMed (June 2007), EMBASE (June 2007), LILACS (June 2007), databases of ongoing trials, and relevant conference proceedings. References of identified trials were searched and the first author of each included trial was contacted. SELECTION CRITERIA Randomised controlled trials that compared rituximab maintenance therapy to observation, treatment at relapse (no maintenance therapy), or other maintenance treatment. DATA COLLECTION AND ANALYSIS Two authors independently appraised the quality of each trial and extracted data from included trials. Hazard ratios (HR) and relative risks with 95% confidence intervals (CI) were estimated and pooled using the fixed-effect model. MAIN RESULTS Five trials including 1056 adult patients were included in the review. Four trials (895 patients) were included in the analysis of overall survival. Patients treated with rituximab as maintenance therapy had a significantly better overall survival compared to observation alone (HR 0.53, 95% CI 0.38 to 0.73). AUTHORS' CONCLUSIONS Rituximab maintenance therapy should be added to standard therapy of patients with relapsed or refractory follicular lymphoma following a successful induction treatment. The drug should be given either as four weekly infusions every six months or as a single infusion every two to three months. Future randomised controlled trials should explore the effect of different protocols of rituximab maintenance therapy on overall survival.

Abstract
Translocation of chromosomes 14 and 18 [t(14;18)] for detection of minimal residual disease in follicular lymphoma patients can be analyzed by nested polymerase chain reaction (PCR) or by quantitative PCR like LightCycler-based assays. We have compared both methods in blood and bone marrow samples of 28 patients enrolled in a clinical study on immunochemotherapy. In 42% of samples, the bcl2-IgH rearrangement was detectable by nested PCR, but not by LightCycler PCR. Nested PCR was able to reveal a significant drop in positive bone marrow or peripheral blood samples after therapy. In contrast, with LightCycler PCR, the detected drop in t(14;18)-positive cells did not reach statistical significance. The majority of patients showed positive results with nested PCR of peripheral blood or bone marrow without any associations to presence or absence of histological bone marrow (BM) infiltration by lymphoma cells. With LightCycler PCR, the numbers of positive cells were higher in samples from patients with BM infiltration of lymphoma cells (1.9 x 10(-2)) compared to samples from patients without involvement (4.08 x 10(-5)). A similar trend was seen in samples derived from the peripheral blood. Positivity for t(14;18) after therapy in two patients correlated with clinical relapse 6 months later. The data shown here demonstrate a lower sensitivity of LightCycler vs. nested PCR for detection of t(14;18). The usefulness of nested PCR for t(14;18) for risk stratification after primary therapy has to be validated in larger trials.

Abstract
BACKGROUND The International Prognostic Index (IPI), initially designed for aggressive lymphomas, is also used in follicular lymphoma (FL) and other indolent lymphomas. Two new prognostic indexes have recently been proposed for FL [the Italian Lymphoma Intergroup (ILI) Index and the Follicular Lymphoma International Prognostic Index (FLIPI)]. PATIENTS AND METHODS Three indexes, IPI [age >60 years, extranodal involvement two or more sites, elevated lactate dehydrogenase (LDH), Eastern Cooperative Oncology Group performance status > or =2, stage > or =3], ILI (age >60 years, extranodal involvement two or more sites, elevated LDH, male sex, B symptoms, erythrocyte sedimentation rate > or =30 mm first hour) and FLIPI (age >60 years, stage > or =3, elevated LDH, nodal involvement five or more, haemoglobin level < or =12 g/dl) were calculated in 411 patients with FL. RESULTS Overall concordance between the three indexes was 54%. A total of 126 (31%) patients were included in the high-risk group according to IPI, 131 (32%) according to ILI and 157 (38%) after FLIPI application. Ten-year overall survival rates after applying the prognostic indexes (IPI, ILI and FLIPI) were, respectively: 72%, 71% and 72%, in the low-risk group; 51%, 60% and 49% in the intermediate-risk group; and 24%, 16% and 31% in the high-risk group. CONCLUSIONS In this series, all three indexes, IPI, ILI and FLIPI, were useful to classify FL patients into differentiated risk groups, although the FLIPI identified a larger proportion of high-risk patients than the IPI and ILI.

Abstract
Lymphoma classification is based on a multiparametric approach to diagnosis, in which clinical features, morphology, immunophenotype, karyotype and molecular characteristics are important to varying degrees. While in most cases, a diagnosis can be confidently established on the basis of morphology and immunophenotype alone, a small proportion of diagnostically difficult cases will rely on molecular studies to enable a definitive diagnosis. This review discusses the various molecular techniques available including Southern blotting (SB), polymerase chain reaction (PCR), fluorescence in situ hybridisation (FISH)--including multicolour-FISH/spectral karyotyping and comparative genomic hybridisation--and also gene expression profiling using cDNA microarray technology. Emphasis is given to the analysis of antigen receptor gene rearrangements and chromosomal translocations as they relate to lymphoma diagnosis and also in the setting of minimal residual disease (MRD) detection and monitoring. Laboratories performing these tests need to have expertise in these areas of testing, and there is a need for greater standardisation of molecular tests. It is important to know the sensitivity and specificity of each test as well as its limitations and the pitfalls in the interpretation of results. Above all, results of molecular testing should never be considered in isolation, and must always be interpreted in the context of clinical and other laboratory data.

Abstract
The evolution of our ability to diagnose and classify lymphomas in an increasingly refined manner has paralleled the development of novel technologic approaches, with contemporary practice dependent upon the harnessing of a plethora of data that include microscopic, immunophenotypic, and genetic information. Although each of these components is currently indispensable, there is a purported progressive improvement in biologic objectivity as one maneuvers through these respective technologies. Accordingly, and in particular given the rapid pace at which key insights into lymphoma biology are emerging with microarray and other cutting-edge technologies, the role of molecular genetic testing is assuming even greater relevance. The ability to diagnose and classify lymphomas more accurately, precisely, and rationally by incorporating molecular data ought to lead to the development of more appropriate directed therapies.

Abstract
Non-Hodgkin lymphoma (NHL) causes many deaths worldwide, and its incidence is increasing. Although some cases are associated with immunodeficiency, autoimmunity, or viral infections, in most cases the causes of NHL are not understood. However, there have been some important advances in our understanding of the development of healthy lymphocytes and the pathogenesis of NHL over the past 10 years. These advances have been accompanied by an improvement in treatment for NHL. Before the late 1990s, the only treatment option available was cytotoxic chemotherapy. In the past 10 years, however, high-dose chemotherapy and autologous stem-cell reconstitution have become established parts of treatment for aggressive lymphoma. Furthermore, monoclonal antibodies have become another therapeutic option. Rituximab (an anti-CD20 monoclonal antibody) is the most advanced monoclonal antibody in clinical trials and has become part of standard treatment for some lymphomas. Rituximab, and many other monoclonal antibodies, continue to be assessed in clinical studies. Monoclonal antibodies can be used alone or in combination with standard-dose or high-dose chemotherapy, and they can also be conjugated to radionuclides to enhance cytotoxicity. Here, we review advances in the treatment of NHL that have occurred over the past 10 years.

Abstract
Follicular lymphoma (FL) is characterized by the activation of BCL2 through t(14;18)(q32;q21). Additional acquired mutations are necessary to generate a fully malignant clonal proliferation. Many of these secondary genetic alterations are visible in the clonal karyotype; however, the sequence by which they arise and their influence on clinical behavior have not been determined. The ability to address these issues has been hampered by the lack of computational methods to manipulate complex chromosomal data in a sufficiently large cohort of cases. In the present investigation, we analyzed secondary karyotypic alterations in 336 cases of FL with t(14;18) to identify the most common regions of recurrent chromosomal gain or loss. This revealed 29 recurrent changes present in more than 5% of the tumors. Each tumor karyotype was then assessed for the presence or absence of each of these 29 specific changes. By statistical means, we show that the chromosomal changes arise in an apparent temporal order, with distinct early and late changes. We identify, by principal-components analysis, four possible cytogenetic pathways that characterize the early stages of clonal evolution, which converge to a common route at later stages. We show that FLs with t(14;18) may be classified into cytogenetic subgroups determined by the presence or absence of 6q-, +7, or der(18)t(14;18). Correlation with clinical outcomes in a subset of cases with clinical data revealed del(17p) and +12 to be correlated with an adverse clinical outcome. The clinical implications of these pathways of clonal evolution need to be examined on a prospective basis in a large cohort of FLs.

This phase I-II study describes the safety of rituximab, ifosfamide, mitoxantrone and etoposide (R-IME) as an induction regimen prior to high-dose chemotherapy and autologous stem cell transplantation (HDC-ASCT), and rituximab given post-HDC-ASCT for B cell non-Hodgkins's lymphoma. This study also measured the effect on disease burden and stem cell contamination. Patients with relapsed, refractory or poor risk B cell lymphomas were eligible. Patients were treated with two cycles of R-IME; all non-progressing patients under-went a third cycle and peripheral blood stem cell (PBSC) collection. Patients underwent HDC-ASCT and those patients in remission after HDC-ASCT were treated with four additional doses of rituximab. Tumor cell contamination was measured at baseline and in the PBSC. Serial immunoglobulin levels were measured. Patients were followed for time to treatment failure (TTF) and overall survival (OS). Thirty-two patients were enrolled. Thirty patients had at least stable disease after two cycles of R-IME. Twenty-nine underwent stem cell collection. The response rate to R-IME induction was 77% (20/26) with 35% (9/26) complete response(CR). Stem cell mobilization was successful in 93% (27/29) of patients. The response rate to R-IME induction and HDC-ASCT was 95% with a confirmed CR of 68%. Median follow-up was 28 months; the median TTFand OS have not been reached. There was a significant decline in stem cell tumor cell contamination and a significant decline in IgG without an increase in infections. Forty-three per cent of patients had transient neutropenia after post-transplant rituximab. R-IME is an effective cytoreductive and mobilization regimen. There appears to be a reduction in the number of lymphoma cells in the stem cell product and the toxicity is manageable.

Abstract
Treatment for patients with stage IV indolent lymphoma ranges from watchful waiting to intensive chemotherapy and stem cell transplantation. In this trial we compared 2 induction regimens followed by 1 year of interferon maintenance therapy. Fludarabine, mitoxantrone (Novantrone), and dexamethasone (FND) were compared with an alternating triple therapy (ATT) regimen (CHOD-Bleo, ESHAP, and NOPP). Maintenance interferon/dexamethasone was given for 1 year in both treatment arms. Endpoints were comparisons of remission rates, survival, failure-free survival (FFS), molecular response rates, and toxicities. One hundred forty-two patients with previously untreated stage IV indolent lymphoma were evaluable (73 on FND; 69 on ATT). The overall response rates were 97% for FND and 97% for ATT (P =.9). The median follow-up is 5.9 years. The 5-year survival rates were 84% with FND and 82% with ATT (P =.9); the 5-year FFS rates were 41% with FND and 50% with ATT (P =.02). In a multivariate analysis, factors predicting for longer FFS were beta(2)-microglobulin less than 3 mg/L (P =.01) and ATT treatment (P =.03). ATT was associated with a substantially higher rate of grade 3-4 toxicities than FND. In conclusion, both regimens were associated with high rates of response and survival. ATT was associated with substantially longer FFS, but it was more toxic than FND.

Abstract
Incidence rates of follicular lymphoma (FL) inexplicably vary markedly between Western and Asian countries. A hallmark of FL is the bcl-2 translocation, characterized by 1 of 2 common breakpoints known as major breakpoint region (MBR) and minor cluster region (mcr). We analyzed previously published data to compare rates of bcl-2 translocation in FL across geographic regions. Available data from the literature suggest that the incidence of bcl-2 in healthy persons in the absence of FL may be as high as 50% in Western and Asian populations. However, in FL our results show that the frequency of bcl-2 positivity was significantly higher for US than for Asian populations (P <.0001). This pattern persisted for MBR and mcr subgroups. We conclude that a significant gradient exists in the bcl-2 frequency between these FL populations. We therefore suggest that the relatively low incidence of FL in Asian populations is caused not by a lower frequency of bcl-2 rearrangements in healthy populations but by distinct molecular pathways developing in different geographic regions that nonetheless culminate in FL, which is morphologically similar but molecularly distinct. Studies demonstrating differences in clinical characteristics according to the presence or absence of bcl-2 rearrangements support this concept. Thus we hypothesize that FL may in fact be a heterogeneous malignancy encompassing entities with distinct molecular pathogenesis and potentially distinct clinical manifestations. If these findings were confirmed in prospective studies, it would imply that different etiologic or genetic factors might influence the development of FL across separate regions.

Abstract
56200 new cases of NHL are expected to be diagnosed in the United States (US) per year. For reasons that are not fully understood, the number of new cases per year has nearly doubled in the past three decades. Most patients with follicular lymphoma are over 50 years of age and present with widespread disease at diagnosis. Nodal involvement is very common, often accompanied by splenic and bone marrow disease. Despite the advanced stage, the median survival ranges from 8 to 12 years. The vast majority of patients with advanced stage follicular lymphoma are not cured using the current therapeutic options. The rate of relapse is fairly consistent over time, even in patients who have achieved complete responses (CRs) to treatment. Therapeutic options in follicular NHL include watchful waiting, oral alkylating agents, purine nucleoside analogues, combination chemotherapy, interferon and monoclonal antibodies. Radiolabelled monoclonal antibodies, autologous or allogeneic bone marrow or peripheral stem cell transplantation are under current clinical evaluation. The approval of rituximab, an unconjugated chimeric antibody against the CD20 antigen for the treatment of relapsed follicular B-cell NHL marked a milestone in the development of antibody treatment. In addition, newer approaches like radioimmunoconjugates with myeloablative activity induced response rates of 80-100% in heavily pretreated patients. Various clinical trials combining monoclonal antibodies with conventional therapies are currently ongoing to determine whether these new biological agents will alter the natural history of follicular lymphoma.

Abstract
PURPOSE To analyze the long-term results with radiotherapy (RT) for early-stage, low-grade follicular lymphomas. METHODS AND MATERIALS From 1960 to 1988, 80 patients with Stage I (n = 33) or II (n = 47), World Health Organization Grade 1 (n = 50) or 2 (n = 30) follicular lymphoma were treated with RT. The lymph nodes or spleen were involved in 97% of cases. The maximal tumor sizes ranged from 0.5 to 11.0 cm (median 2.0). The RT fields encompassed only the involved Ann Arbor nodal region (involved-field RT) in 9% of the patients. The fields also included 1-3 adjacent, grossly uninvolved nodal regions (regional RT) in 54% of patients but were smaller than mantle or whole abdominopelvic fields. Mantle or whole abdominopelvic fields encompassing up to 6 grossly uninvolved regions (extended-field RT) were used in the remaining 37% of patients. The total RT doses ranged from 26.2 to 50.0 Gy given in daily 1.0-3.0-Gy fractions. RESULTS The follow-up of the surviving patients ranged from 3.5 to 28.7 years (median 19.0). No recurrences were found >17.0 years after RT, with 13 patients free of disease at their last follow-up visit 17.6-25.0 years after treatment. In 58% of cases, death was not from follicular lymphoma. The 15-year local control rate was 100% for 44 lymphomas <3.0 cm treated with only 27.8-30.8 Gy (median 30.0 in 20 fractions). Progression-free survival was affected by the maximal tumor size at the start of RT (15-year rate 49% vs. 29% for lymphomas <3.0 cm vs. > or =3.0 cm, respectively, p = 0.04) and Ann Arbor stage (15-year rate 66% vs. 26% for Stages I and II, respectively, p = 0.006). Ann Arbor stage also affected the cause-specific survival (15-year rate 87% vs. 54% for Stages I and II, respectively, p = 0.01). No significant difference was found in overall survival between those treated with extended-field RT and those treated with involved-field RT or regional RT (15-year rate 49% and 40%, respectively, p = 0.51). The 15-year incidence rate of Grade 3 or greater late complications according to the Subjective, Objective, Management, and Analytical scale in patients treated with 26.2-30.8 Gy vs. 30.9-50.0 Gy was 0% and 6%, respectively. CONCLUSIONS RT can cure approximately one half of Stage I and one quarter of Stage II, World Health Organization Grade 1 or 2 follicular lymphomas. Follicular lymphomas <3.0 cm can be controlled locally with doses of 27.8-30.8 Gy, and there is a trend toward a higher incidence of late complications with doses of >30.8 Gy. Doses of 25-30 Gy delivered in 15-20 fractions should be examined prospectively in patients with follicular lymphomas of <3.0 cm.

Abstract
In follicular lymphoma, the t(14;18) status of the peripheral blood and bone marrow analyzed by polymerase chain reaction (PCR) is assumed to correlate with disease activity in patients with relapsed disease. The clinical significance of quantitating circulating lymphoma cells by real-time PCR is reported in patients on first-line treatment. Thirty-four consecutive patients with previously untreated follicular lymphoma and detectable t(14;18)-positive cells in pretreatment peripheral blood samples were monitored. All patients were treated with standard chemotherapy in combination with interferon alfa-2b. Before and after induction therapy, blood samples were taken for quantitative analysis of t(14;18). At presentation, a median of 262 t(14;18)-positive cells per 75,000 normal cells was found (range, 1-75 000). Patients with lower numbers of circulating tumor cells more frequently had bulky disease (P =.02). Seventy-nine percent of the patients responded clinically to treatment. In 22 of 28 patients, including 4 patients in whom treatment had failed clinically, the number of circulating t(14;18)-positive cells decreased to undetectable or low levels after therapy. In the remaining responding patients, circulating tumor cells persisted after therapy. These quantitative data on circulating t(14;18)-positive cells call into question the usefulness of molecular monitoring of the blood in a group of patients with follicular lymphoma uniformly treated with a noncurative first-line regimen. T(14;18)-positive cells decreased in peripheral blood after treatment, irrespective of the clinical response. Therefore, the significance of so-called molecular remission should be reconsidered in follicular lymphoma. (Blood. 2001;98:940-944)

Abstract
Treatment for extensive indolent lymphoma should provide optimization of efficacy while avoiding excessive toxicity. Rituximab may be an ideal agent to combine with chemotherapy because of its lack of classical myelotoxicity. In this study, 27 patients with a variety of histologies of indolent B-cell non-Hodgkin's lymphoma have been treated utilizing a novel three-drug combination. Nine patients had relapsed disease and 18 were previously untreated. Patients first received cyclophosphamide 800 mg/m(2) and mitoxantrone 8 mg/m(2) i.v. on day 1, every 3 weeks for 2 cycles. Subsequently, patients received rituximab 375 mg/m(2) followed by mitoxantrone 8 mg/m2 every 2 weeks for 4 cycles. This regimen and, in particular, the rituximab infusion were extremely well tolerated. Only two of 27 patients experienced a grade 1/2, infusion-related reaction during the first rituximab infusion. Grade 4 neutropenia was noted at some point in 16 patients who were then offered granulocyte-macrophage colony-stimulating factor support for improvement of neutropenia. No infections were noted. Alopecia was minimal. Of 27 patients, 19 achieved a complete response (CR), one achieved an unconfirmed CR (CRu), and five patients achieved a partial response, for an overall response rate of 92.5%. Molecular remissions were noted in seven of 12 tested patients in CR. We concluded that the cyclophosphamide/mitoxantrone/rituximab (CyMiR) regimen is effective and extremely well tolerated. Furthermore, rituximab infusion-associated morbidity is markedly reduced.
