A Retrospective Cohort Study of Treatment Outcomes of Adult Patients With Relapsed or Refractory Follicular Lymphoma (ReCORD-FL). Hemasphere 2022; 6:e745. [PMID: 35813099 PMCID: PMC9263496 DOI: 10.1097/hs9.0000000000000745] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 05/20/2022] [Indexed: 11/04/2022] Open
Abstract
This study (ReCORD-FL) sought to construct a historical control cohort to augment single-arm trials in relapsed/refractory follicular lymphoma (r/r FL). A retrospective study in 10 centers across North America and Europe was conducted. Adults with grade 1–3A FL were required to be r/r after ≥2 therapy lines including an anti-CD20 and an alkylator. After first becoming r/r, patients were required to initiate ≥1 additional therapy line, which defined the study index date. Endpoints were observed from start of each therapy line (including index line) until death, last follow-up, or December 31, 2020. Endpoints were complete response (CR) rate, overall response rate (ORR), time to next treatment or death (TNT-D), event-free survival (EFS), and overall survival (OS). One hundred eighty-seven patients were identified. Most patients’ (80.2%) index therapy occurred in third line (3L) (range, 3L–6L). Median follow-up from FL diagnosis was 9 years (range, 1–21 years). CR and ORR to the index therapy were 39.0% and 70.6%, respectively. Median (95% confidence interval) EFS from index was 14.6 (11.0-18.0) months; median OS from index was 10.6 years. Outcomes worsened across successive treatment lines and for patients who were double refractory (r/r to both an anti-CD20 monoclonal antibody and an alkylator) or POD24 (progressed ≤24 months after front-line anti-CD20) at index. Findings demonstrate the unmet need of FL patients with multiply relapsed, double refractory, or POD24 disease. Based on robustness of the historical data collected and comparability with a previous study (SCHOLAR-5), ReCORD-FL presents a valuable source of control data for comparative studies in r/r FL.

Abstract
This open-label phase 2 study (CONTRALTO) assessed the safety and efficacy of BCL-2 inhibitor venetoclax (VEN) plus rituximab (R), and VEN plus bendamustine (B) and R, vs B + R (BR) alone in relapsed/refractory (R/R) follicular lymphoma. Patients in the chemotherapy-free arm (arm A: VEN + R) received VEN 800 mg/d plus R 375 mg/m2 on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 4, 6, 8, 10, and 12. After a safety run-in with VEN 600 mg, patients in the chemotherapy-containing cohort were randomized to either VEN + BR (arm B; VEN 800 mg/d for 1 year + 6 cycles of BR [B 90 mg/m2 on days 1 and 2 and R 375 mg/m2 on day 1]) or 6 cycles of BR (arm C). Overall, 163 patients were analyzed (9 in the safety run-in and 52, 51, and 51 in arms A, B, and C, respectively). Complete metabolic/complete response rates were 17% (arm A), 75% (arm B), and 69% (arm C). Of patients in arm B, only 61% received ≥90% of the planned B dose vs 96% of patients in arm C. More frequent hematologic toxicity resulted in more reduced dosing/treatment discontinuation in arm B vs arm C. Rates of grade 3/4 adverse events were 51.9%, 93.9%, and 60.0% in arms A, B, and C, respectively. VEN + BR led to increased toxicity and lower dose intensity of BR than in arm C, but efficacy was similar. Optimizing dose and schedule to maintain BR dose intensity may improve efficacy and tolerability of VEN + BR, while VEN + R data warrant further study. This study was registered at www.clinicaltrials.gov as #NCT02187861.

Abstract
Follicular lymphoma (FL) is a systemic neoplasm of the lymphoid tissue displaying germinal centre (GC) B cell differentiation. FL represents ~5% of all haematological neoplasms and ~20-25% of all new non-Hodgkin lymphoma diagnoses in western countries. Tumorigenesis starts in precursor B cells and becomes full-blown tumour when the cells reach the GC maturation step. FL is preceded by an asymptomatic preclinical phase in which premalignant B cells carrying a t(14;18) chromosomal translocation accumulate additional genetic alterations, although not all of these cells progress to the tumour phase. FL is an indolent lymphoma with largely favourable outcomes, although a fraction of patients is at risk of disease progression and adverse outcomes. Outcomes for FL in the rituximab era are encouraging, with ~80% of patients having an overall survival of >10 years. Patients with relapsed FL have a wide range of treatment options, including several chemoimmunotherapy regimens, phosphoinositide 3-kinase inhibitors, and lenalidomide plus rituximab. Promising new treatment approaches include epigenetic therapeutics and immune approaches such as chimeric antigen receptor T cell therapy. The identification of patients at high risk who require alternative therapies to the current standard of care is a growing need that will help direct clinical trial research. This Primer discusses the epidemiology of FL, its molecular and cellular pathogenesis and its diagnosis, classification and treatment.

Abstract
The use of immunochemotherapy has improved the outcome of follicular lymphoma (FL). Recently, complete response at 30 months (CR30) has been suggested as a surrogate for progression-free survival. This study aimed to analyse the life expectancy of FL patients according to their status at 30 months from the start of treatment in comparison with the sex and age-matched Spanish general population (relative survival; RS). The training series comprised 263 patients consecutively diagnosed with FL in a 10-year period who needed therapy and were treated with rituximab-containing regimens. An independent cohort of 693 FL patients from the Grupo Español de Linfomas y Trasplante Autólogo de Médula Ósea (GELTAMO) group was used for validation. In the training cohort, 188 patients were in CR30, with a 10-year overall survival (OS) of 53% and 87% for non-CR30 and CR30 patients, respectively. Ten-year RS was 73% and 100%, showing no decrease in life expectancy for CR30 patients. Multivariate analysis indicated that the FL International Prognostic Index was the most important variable predicting OS in the CR30 group. The impact of CR30 status on RS was validated in the independent GELTAMO series. In conclusion, FL patients treated with immunochemotherapy who were in CR at 30 months showed similar survival to a sex- and age-matched Spanish general population.

Association of early disease progression and very poor survival in the GALLIUM study in follicular lymphoma: benefit of obinutuzumab in reducing the rate of early progression. Haematologica 2018; 104:1202-1208. [PMID: 30573503 PMCID: PMC6545851 DOI: 10.3324/haematol.2018.209015] [Citation(s) in RCA: 64] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Accepted: 12/17/2018] [Indexed: 12/26/2022] Open
Abstract
We evaluated early disease progression and its impact on overall survival (OS) in previously untreated follicular lymphoma patients in GALLIUM (clinicaltrials.gov identifier: 01332968), and investigated the effect on early disease progression of the two randomization arms: obinutuzumab-based versus rituximab-based immunochemotherapy. Cause-specific Cox regression was used to estimate the effect of treatment on the risk of disease progression or death due to disease progression within 24 months of randomization and to analyze OS in patients with or without disease progression after 24 months. Mortality in both groups was analyzed 6, 12, and 18 months post randomization (median follow up, 41 months). Fewer early disease progression events occurred in obinutuzumab (57 out of 601) versus rituximab (98 out of 601) immunochemotherapy patients, with an average risk reduction of 46.0% (95%CI: 25.0-61.1%; cumulative incidence rate 10.1% vs. 17.4%). At a median post-progression follow up of 22.6 months, risk of mortality increased markedly following a progression event [HR of time-varying progression status, 25.5 (95%CI: 16.2-40.3)]. Mortality risk was higher the earlier patients progressed within the first 24 months. Age-adjusted HR for OS after 24 months in surviving patients with disease progression versus those without was 12.2 (95%CI: 5.6-26.5). Post-progression survival was similar by treatment arm. In conclusion, obinutuzumab plus chemotherapy was associated with a marked reduction in the rate of early disease progression events relative to rituximab plus chemotherapy. Early disease progression in patients with follicular lymphoma was associated with poor prognosis, with mortality risk higher after earlier progression. Survival post progression did not seem to be influenced by treatment arm.

A simplified scoring system in de novo follicular lymphoma treated initially with immunochemotherapy. Blood 2018; 132:49-58.

Abstract
In follicular lymphoma (FL), no prognostic index has been built based solely on a cohort of patients treated with initial immunochemotherapy. There is currently a need to define parsimonious clinical models for trial stratification and to add on biomolecular factors. Here, we confirmed the validity of both the follicular lymphoma international prognostic index (FLIPI) and the FLIPI2 in the large prospective PRIMA trial cohort of 1135 patients treated with initial R-chemotherapy ± R maintenance. Furthermore, we developed a new prognostic tool comprising only 2 simple parameters (bone marrow involvement and β2-microglobulin [β2m]) to predict progression-free survival (PFS). The final simplified score, called the PRIMA-PI (PRIMA-prognostic index), comprised 3 risk categories: high (β2m > 3 mg/L), low (β2m ≤ 3 mg/L without bone marrow involvement), and intermediate (β2m ≤ 3 mg/L with bone marrow involvement). Five-year PFS rates were 69%, 55%, and 37% in the low-, intermediate-, and high-risk groups, respectively (P < .0001). In addition, achieving event-free survival (EFS) or not at 24 months (EFS24) was a strong posttreatment prognostic parameter for subsequent overall survival, and the PRIMA-PI was correlated with EFS24. The results were confirmed in a pooled external validation cohort of 479 patients from the FL2000 LYSA trial and the University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellence Molecular Epidemiology Resource. Five-year EFS in the validation cohort was 77%, 57%, and 44% in the PRIMA-PI low-, intermediate-, and high-risk groups, respectively (P < .0001). The PRIMA-PI is a novel and easy-to-compute prognostic index for patients initially treated with immunochemotherapy. This could serve as a basis for building more sophisticated and integrated biomolecular scores.

Abstract
The aim of this project was to define indications for hematopoietic stem cell transplantation in follicular lymphoma in Europe. In the absence of evidence-based data, a RAND-modified Delphi procedure was used by an expert panel. After pre-defining statements, these were individually/anonymously scored by each participant using a 9-point scale. Consensus was reached that: 1) high-dose therapy with autologous stem cell rescue is not an appropriate option to consolidate first remission in patients responding to immuno-chemotherapy outside clinical trials; 2) in patients with first chemo-sensitive relapse, high-dose therapy with autologous stem cell rescue is an appropriate option to consolidate remission, especially in patients with a short response after immuno-chemotherapy or with high-risk FLIPI; 3) high-dose therapy with autologous stem cell rescue is also appropriate in second/subsequent chemo-sensitive relapses; 4) allotransplant (preferably a reduced intensity conditioning-allotransplant) should be considered at relapse after high-dose therapy with autologous stem cell rescue. No consensus was reached on the role of high-dose therapy with autologous stem cell rescue in low-risk first relapse, or on when an allotransplant should be preferred over high-dose therapy with autologous stem cell rescue. In the absence of evidence-based data, the consensus method used was a valuable tool to define indications for hematopoietic stem cell transplant in follicular lymphoma.

Abstract
BACKGROUND AND OBJECTIVE Elevated serum beta-2 microglobulin (β2-M) has previously been reported in non-Hodgkin lymphoma (NHL) patients. This study examined the association between serum β2-M and the prognosis of NHL and analyzed its predictive value. METHOD A total of 287 NHL patients from Taiyuan, Shanxi, China, participated in a prospective cohort study between 2008 and 2011. Overall survival (OS) was compared between NHL patients with high and normal β2-M levels using the log-rank test. Three standard Cox regression models including the International Prognostic Index (IPI) score, β2-M or IPI score+β2-M as independent variables were constructed. The time-dependent receiver operating characteristic curves method and C index were used to examine the tendency of the models' predictive accuracy over time. RESULTS NHL patients with elevated β2-M values had worse OS (p<0.001) and higher mortality risk (HR=1.93, 95% CI 1.37-2.77, p<0.001) than patients with normal β2-M values. There were statistically significant differences between the C indexes for the models with IPI+β2-M, IPI or β2-M alone (p<0.001). CONCLUSION Our results demonstrated an association between serum β2-M and NHL prognosis. Combining β2-M with IPI may help to improve the prognostic accuracy of NHL.

Abstract
Using a retrospective claims database, we estimated the economic costs of progression among patients with follicular non-Hodgkin lymphoma (f-NHL) treated in an outpatient community-based setting. Patients with f-NHL who received care between 1 July 2006 and 31 December 2009 were categorized into two cohorts based on whether they experienced progressive disease (PD) or not. Costs per patient per month (PPPM) were compared between patients with PD versus non-PD. Follow-up time was censored at the last entry for disease status or 6 months after the date of remission/stable disease or progression. Of the 1002 patients with f-NHL identified, 268 progressed and 734 did not. The mean overall costs PPPM over the 6-month follow-up period were significantly higher for patients with PD versus non-PD ($3527 vs. $860; difference = $2667; p < 0.001). This cost difference persisted within all resource categories evaluated. Results of this study indicate that therapies which delay progression for patients with f-NHL may result in potential cost savings.

Abstract
Alpha interferon has proven efficacy in prolonging remissions in patients with follicular non-Hodgkin lymphoma (NHL) when given concurrently with or after conventional-dose anthracycline-based chemotherapy, but there are limited data on its use after myeloablative conditioning. We prospectively evaluated the toxicity and efficacy of interferon given thrice weekly for up to 5 years post-engraftment in patients with relapsed follicular NHL undergoing autologous stem cell transplant using busulfan-melphalan conditioning. Thirty-seven patients were enrolled in this Australasian Leukaemia & Lymphoma Group study and transplanted between 1995 and 1999. Only one patient had received prior rituximab. Two patients died of transplant-related toxicity; 28 of the remainder commenced interferon, but it was discontinued prematurely in most patients due to toxicity (mainly fatigue and depression) or relapse. While the majority of patients (29/36 evaluable: 81%) achieved a complete remission based on clinical and CT scan criteria post-transplant, most relapsed relatively early, with a median progression-free survival of 2.4 years. The overall survival at 7 years was 49%. Eight patients (22%), however, remain alive a median of 9.3 years post-transplant, having never relapsed, and another six patients (16%) remain alive in durable remission after salvage therapy. These results demonstrate that interferon is poorly tolerated post-autograft and hence is unlikely to positively contribute to patient outcome. Long-term follow-up demonstrates that autografting may result in durable remissions in a meaningful minority of patients with relapsed follicular NHL.

Abstract
Indolent non-Hodgkin lymphoma (NHL) comprises a group of incurable, generally slow-growing lymphomas highly responsive to initial therapy, with a relapsing and progressive course. Rituximab, an anti-CD20 antibody, has had a large impact on the treatment of indolent NHL. Its effectiveness as a single agent and in conjunction with known chemotherapy regimens has made it a standard of care in the treatment of NHL. Analysis of data obtained from NHL clinical trials, as well as data from the National Cancer Institute, indicate that the overall survival (OS) of patients with indolent NHL has improved since the discovery of rituximab. Given its effectiveness and tolerability, rituximab is currently being investigated as a maintenance agent with encouraging results. This review summarizes several landmark trials utilizing rituximab as a single agent and in combination with chemotherapy for treatment of NHL. In addition, a review of the studied rituximab maintenance dosing schedules and its impact on NHL will be presented. Overall, rituximab has changed the landscape for treatment of indolent NHL; however, additional research is necessary to identify the optimal dosing schedule, as well as patients most likely to respond to prolonged rituximab therapy.

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
Several factors predict outcome for patients with non-Hodgkin's lymphoma (NHL) after chemotherapy. However, predictors of response to rituximab have not been identified. Baseline characteristics for 166 NHL patients (130 follicular) in a phase III trial of rituximab were analysed by univariate and multivariate methods to determine whether any of 27 factors predict response and/or response duration. In a univariate analysis, response to rituximab was associated with follicular histology, no prior fludarabine therapy, prior autologous bone marrow transplantation (ABMT), lack of bone marrow involvement or extranodal disease, positive bcl-2 in blood, and fewer relapses. By univariate analysis, longer median time to progression (TTP) and/or duration of response (DR) after rituximab therapy was associated with International Prognostic Index lower-risk group, multiagent chemotherapy, and low/normal serum lactate dehydrogenase (LDH) or beta2 microglobulin. In the multivariate analysis, response to rituximab correlated with follicular histology, prior ABMT, multiagent chemotherapy, and no bone marrow involvement; longer TTP and/or DR correlated with low/normal serum LDH or beta2 microglobulin, high CD3+ cells, and response to last chemotherapy. The follicular lymphoma international prognostic index (FLIPI) did not correlate consistently with response to rituximab or response duration. Several factors associated with prognosis following chemotherapy did not correlate with response to rituximab or response duration. NHL patients can respond to rituximab despite having factors associated with a poor outcome to chemotherapy.

Abstract
PURPOSE Optimal therapy of follicular lymphoma (FL) is not defined. We analyzed a large prospective cohort study to identify current demographics and patterns of care of FL in the United States. PATIENTS AND METHODS The National LymphoCare Study is a multicenter, longitudinal, observational study designed to collect information on treatment regimens and outcomes for patients with newly diagnosed FL in the United States. Patients were enrolled between 2004 and 2007. There is no study-specific prescribed treatment regimen or intervention. RESULTS Two thousand seven hundred twenty-eight subjects were enrolled at 265 sites, including the 80% of patients enrolled from nonacademic sites. Using the Follicular Lymphoma International Prognostic Index (FLIPI), three distinct groups independent of histologic grade could be defined. Initial therapeutic strategy was: observation, 17.7%; rituximab monotherapy, 13.9%; clinical trial 6.1%; radiation therapy, 5.6%; chemotherapy only, 3.2%; chemotherapy plus rituximab, 51.9%. Chemotherapy plus rituximab regimens were: rituximab plus cyclophosphamide, doxorubicin, vincristine, prednisone, 55.0%; rituximab plus cyclophosphamide, vincristine, and prednisone, 23.1%; rituximab plus fludarabine based, 15.5%; other, 6.4%. The choice to initiate therapy rather than observe was associated with age, FLIPI, stage, and grade (P < .01). Significant differences in treatment (P < .01) across regions of the United States were noted. Contrary to practice guidelines, treatment of stage I FL frequently omits radiation therapy. CONCLUSION Widely disparate therapeutic approaches are utilized for FL. Initial therapy is deferred in a small subset of patients. There is no single standard of care for the treatment of de novo FL, although antibody use is ubiquitous when therapy is initiated. These disparate approaches to the initial care of patients with FL render a heterogeneous group of patients at relapse.

Abstract
Purpose To study the clinical significance of transformation to diffuse large B-cell lymphoma (DLBCL) in patients with follicular lymphoma (FL). Patients and Methods From 1972 to 1999, 325 patients were diagnosed with FL at St Bartholomew's Hospital (London, United Kingdom). With a median follow-up of 15 years, progression occurred in 186 patients and biopsy-proven transformation in 88 of the 325. The overall repeat biopsy rate was 70%. Results The risk of histologic transformation (HT) by 10 years was 28%, HT not yet having been observed after 16.2 years. The risk was higher in patients with advanced stage (P = .02), high-risk Follicular Lymphoma International Prognostic Index (FLIPI; P = .01), and International Prognostic Index (IPI; P = .04) scores at diagnosis. Expectant management (as opposed to treatment being initiated at diagnosis) also predicted for a higher risk of HT (P = .008). Older age (P = .005), low hemoglobin level (P = .03), high lactate dehydrogenase (P < .0001), and high-risk FLIPI (P = .01) or IPI (P = .003) score at the time of first recurrence were associated with the diagnosis of HT in a biopsy performed at that time. The median survival from transformation was 1.2 years. Patients with HT had a shorter overall survival (P < .0001) and a shorter survival from progression (P < .0001) than did those in whom it was not diagnosed. Conclusion Advanced stage and high-risk FLIPI and IPI scores at diagnosis correlate with an increased risk of HT. This event strongly influences the outcome of patients with FL by shortening their survival. There may be a subgroup of patients in whom HT does not occur.

Abstract
BACKGROUND Histological transformation (HT) is a well-known event in patients with follicular lymphoma (FL) conferring an unfavorable prognosis. The aim of the study was to analyze incidence and risk factors for HT in a large series of FL patients. PATIENTS AND METHODS 276 patients (median age: 54 years; M139/F137) diagnosed with FL (42% grade 1, 51% 2, 7% 3) in a single institution were studied. Initial treatment consisted of combined chemotherapy in most cases. Median survival was 11.3 years. Main clinic and biological variables were assessed for HT and survival. RESULTS 30 of 276 patients (11%) presented HT after a median follow-up of 6.5 years, with a risk of 15% and 22% at 10 and at 15 years, respectively. All HT corresponded to diffuse large B-cell lymphoma (DLBCL). Grade 3 histology, nodal areas >4, increased LDH and beta(2)-microglobulin, and high-risk IPI and FLIPI were associated with HT. In multivariate analysis, grade 3 histology and FLIPI retained prognostic significance. Only FLIPI predicted HT in grade 1-2 patients. 28 patients received salvage treatment for HT, with a CR rate of 52%. Median survival from transformation was 1.2 years, with 6/13 CR patients being alive >5 years after HT. CONCLUSION FLIPI and histology were the most important variables predicting HT. Upon HT, only patients achieving CR reached prolonged survival, thus emphasizing the need for effective therapies once this event occurs.

Abstract
We evaluated the role of rituximab (R) both in remission induction and maintenance treatment of relapsed/resistant follicular lymphoma (FL). A total of 465 patients were randomized to induction with 6 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) (every 3 weeks) or R-CHOP (R: 375 mg/m(2) intravenously, day 1). Those in complete remission (CR) or partial remission (PR) were randomized to maintenance with R (375 mg/m(2) intravenously once every 3 months for a maximum of 2 years) or observation. R-CHOP induction yielded an increased overall response rate (CHOP, 72.3%; R-CHOP, 85.1%; P < .001) and CR rate (CHOP, 15.6%; R-CHOP, 29.5%; P < .001). Median progression-free survival (PFS) from first randomization was 20.2 months after CHOP versus 33.1 months after R-CHOP (hazard ratio [HR], 0.65; P < .001). Rituximab maintenance yielded a median PFS from second randomization of 51.5 months versus 14.9 months with observation (HR, 0.40; P < .001). Improved PFS was found both after induction with CHOP (HR, 0.30; P < .001) and R-CHOP (HR, 0.54; P = .004). R maintenance also improved overall survival from second randomization: 85% at 3 years versus 77% with observation (HR, 0.52; P = .011). This is the first trial showing that in relapsed/resistant FL rituximab maintenance considerably improves PFS not only after CHOP but also after R-CHOP induction.

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.

Abstract
This article addresses the problem of incorporating information regarding the effects of treatments or interventions into models for repeated cancer relapses. In contrast to many existing models, our approach permits the impact of interventions to differ after each relapse. We adopt the general model for recurrent events proposed by Peña and Hollander, in which the effect of interventions is represented by an effective age process acting on the baseline hazard rate function. To accommodate the situation of cancer relapse, we propose an effective age function that encodes three possible therapeutic responses: complete remission, partial remission, and null response. The proposed model also incorporates the effect of covariates, the impact of previous relapses, and heterogeneity among individuals. We use our model to analyse the times to relapse for 63 patients with a particular subtype of indolent lymphoma and compare the results to those obtained using existing methods.

Abstract
PURPOSE To evaluate two potential approaches to predicting site-specific patterns of recurrence after yttrium-90 ibritumomab tiuxetan radioimmunotherapy (RIT) for CD20+ B-cell Non-Hodgkin's lymphoma. These predictive methods may be useful in evaluating the utility of local intensification of individual nodal or extranodal sites using external beam radiotherapy. METHODS AND MATERIALS Records and images were evaluated for 20 patients previously treated with yttrium-90 ibritumomab RIT. Intensity of isotope uptake on the pretreatment two-dimensional antibody scans and maximal extent of tumor deposits found on computed tomography images of each anatomic site were correlated with response and subsequent patterns of recurrence or progression. RESULTS Our data failed to suggest a significant correlation between the site-by-site two-dimensional image intensity on the pre-RIT scan and the likelihood of response at those sites. In contrast, an analysis of pretreatment target volumes did correlate significantly with progression. A collective analysis of disease sites from all 20 patients found that 83% (10/12) sites of "bulky" (maximal diameter > or = 5 cm) disease displayed evidence of progression vs. 28% (26/93) of "nonbulky" disease sites containing gross disease but no area measuring >5 cm (p < 0.001). All patients with at least one site of bulky disease had initial disease progression occur at a bulky site, with a bulky site being the sole first site of progression in approximately 50%. In patients with only nonbulky disease sites, approximately one third progressed initially at an entirely new site of disease. CONCLUSION We conclude that we can use tumor bulk to establish a statistical hierarchy of likely tumor progression sites and use this pattern to direct the use of additional external beam radiotherapy to augment treatment.

Abstract
PURPOSE Therapeutic options for relapsed or refractory follicular lymphoma include combination chemotherapy, immunotherapy and, for selected patients, autotransplant. Because of the different mechanisms of action and non-overlapping toxicities, combination of rituximab with chemotherapy is a rational approach. METHODS 30 patients with follicular non-Hodgkin's lymphoma with advanced-stage disease were treated with four cycles of immunochemotherapy with rituximab 375 mg/m2 on day 1, vincristine 2 mg i.v. on day 2 and cyclophosphamide 400 mg/m2 i.v. from days 2 to 6, repeated at 3-week intervals. All patients had received multiple lines of therapy (median 3); 9 (30%) had relapses (2 after high-dose therapy with autologous transplant), and 21 (70%) were in relapse and refractory to salvage treatment (with an anthracycline-containing regimen in 19). RESULTS Of 29 patients evaluable for response, 16 (55 %) obtained a complete response (CR) and 3 (10%) a partial response (PR), with an overall response rate of 65% (19/29); 10 patients (35%) achieved less than PR. The median event-free survival was 16.1 months for all patients, being 22.8 months for responders. After a median follow-up of 2 years from the start of therapy (range 6 months to 3.8 years), of 16 patients who achieved CR, 10 remain free of disease. CONCLUSION The combination of rituximab with vincristine and 5-day cyclophosphamide is able to produce CR in patients with advanced follicular lymphoma, even in patients resistant to third-generation regimens. The regimen designed on the basis of pharmacokinetics of the chimeric antibody seemed important for the clinical efficacy of the combination.

Abstract
Autologous hematopoietic stem cell transplantation (AHSCT) in low-grade non-Hodgkin lymphoma (NHL) can result in a prolonged remission, although most patients eventually relapse and die of their disease. We report long-term outcomes of AHSCT for patients with relapsed low-grade NHL. Between May 1983 and 2001, 67 patients with relapsed or refractory stage III and IV low-grade NHL received an AHSCT at the University of Minnesota at a median of 2.3 years (range, 0.4-15.2 years) after diagnosis. At transplantation, 62 patients (92%) were in complete remission (CR) (6%) or partial remission (PR) (86%); 5 (8%) had resistant disease; and 9 (14%) had transformed to a higher-grade NHL. After AHSCT, 32 (49%) of 65 evaluable patients achieved CR, and 26 (40%) achieved PR. Overall survival (OS) was 50% (95% confidence interval [CI], 38%-62%) at 4 years and 33% (95% CI, 20%-46%) at both 10 and 18 years, whereas progression-free survival (PFS) was 28% (95% CI, 17%-39%) at 4 years, 18% (95% CI, 8%-28%) at 10 years, and 14% (95% CI, 4%-25%) at 18 years. Transplant-related mortality in the first 100 days was 3% (95% CI, 0%-7%). Relapse occurred in 62% (95% CI, 48%-75%) at 4 years and 72% (95% CI, 56%-87%) at 10 years. Eleven patients (16%) developed myelodysplastic syndrome/acute myeloid leukemia 1 to 8 years after AHSCT, and 3 (5%) developed solid tumors. In multiple regression analysis, the International Prognostic Index (IPI) score at transplantation was the most significant predictor for both OS and PFS. The median OS has not been reached in patients with an IPI score of 0 or 1 at transplantation (20 of 35 survive 2 to 18 years after AHSCT), whereas it was 2.3 and 1.6 years for IPI scores of 2 and 3, respectively ( P = .002). A good response (CR/PR) to AHSCT (relative risk [RR], 0.4; 95% CI, 0.2-0.9; P = .04) and age <50 years (RR, 0.5; 95% CI, 0.2-0.8; P = .01) were also independently significant predictors of good OS and PFS. We present mature follow-up data (median follow-up, 8 years; range, 2-18 years) of patients undergoing AHSCT for relapsed low-grade NHL and demonstrate extended OS and PFS. Very long-term remissions were seen in nearly 20% of patients. AHSCT remains promising, especially for patients with sensitive relapse and lower IPI scores. Recurrent lymphoma after AHSCT remains the major problem, and prolonged survival is further tempered by a significant risk of post-transplantation second malignancies, including myelodysplastic syndrome/acute myeloid leukemia and solid tumors.

Abstract
BACKGROUND Different prognostic scores have been proposed to predict the outcome of follicular lymphoma (FL) patients at diagnosis. A new prognostic index specifically addressing FL patients, the Follicular Lymphoma International Prognostic Index (FLIPI), has recently been developed, which might also be useful in patients with progression. PATIENTS AND METHODS One hundred and three patients (55 male, 48 female; median age 59 years) with FL in first relapse/progression after an initial response to therapy (50 complete responders/ 53 partial responders) were included in the study. RESULTS Five-year survival from progression (SFP) was 55% (95% confidence interval 44%-66%). The distribution according to the FLIPI at relapse was 39% good prognosis, 24% intermediate prognosis and 37% poor prognosis. Five-year SFP for these groups were 85%, 79% and 28%, respectively (P < 0.0001). Other variables at relapse with prognostic significance for SFP were age, presence of B symptoms, performance status, bulky disease, number of involved nodal sites, lactate dehydrogenase level, hemoglobin level, histological transformation, the Italian Lymphoma Intergroup prognostic index for FL and the International Prognostic Index for aggressive lymphomas. In the multivariate analysis bulky disease (P=0.01), presence of B symptoms (P=0.03) and FLIPI at relapse (P=0.0003) were the most important variables for predicting SFP. CONCLUSIONS In patients with FL at first relapse/progression, the FLIPI, along with the presence of bulky disease and B symptoms, are features that predict SFP and thus could be useful to select candidates for experimental treatments.

Abstract
BACKGROUND The objective of this study was to estimate the ideal proportion of new patients with lymphoma who should receive radiotherapy at some time during the course of their illness, based on the best evidence. METHODS Available evidence of the efficacy of radiotherapy in most clinical situations for lymphoma were identified through extensive literature reviews and treatment guideline searches. Epidemiologic data concerning the distribution of histologic type, disease stage, and other factors that influence the use of radiotherapy were identified. Decision trees were constructed to merge the evidence-based recommendations with the epidemiologic data to calculate the optimal proportion of patients who should receive radiotherapy according to the best available evidence. Actual radiotherapy utilization rates also were identified. RESULTS The proportion of patients with lymphoma in Australia that should receive radiotherapy at some point in their management, according to the best available evidence, was calculated at 65.0%. Multivariate analysis with a Monte Carlo simulation yielded a radiotherapy utilization rate of 64.4%. The actual utilization rates of radiotherapy for lymphoma reported in clinical practice were 22-29%, substantially lower than the optimal rate calculated in this project. CONCLUSIONS Further research will be required to identify why more patients who are diagnosed with lymphoma are not treated with radiotherapy.

Abstract
INTRODUCTION As serological immunomarkers like neopterin, beta2-microglobulin, soluble IL-2 receptor (sIL-2R) and IL-6 have been described to be elevated in various malignancies, the aim of this study was to investigate whether they would be of diagnostic and prognostic value for leukemic and non-leukemic cutaneous T cell lymphoma (CTCL). PATIENTS AND METHODS Forty-one CTCL patients from the lymphoma clinics of the Department of Dermatology, University of Zurich, were tested for the serum levels of the above-mentioned immunomarkers at several time points, and clinical status and clinical outcome were recorded. Thirty-nine patients with CBCL and T cell inflammatory diseases served as controls. RESULTS The study revealed that neopterin, beta2-MG and sIL-2R are significantly elevated in Sezary syndrome, whereby sIL-2R seemed to be the most sensitive marker and is typically increased in Sezary syndrome. Moreover, there is a correlation between tumor burden index values and serum parameters. Concerning the outcome of the disease (progression versus non-progression), only neopterin showed a significant prognostic value in non-leukemic CTCL patients. CONCLUSION Serological immunomarkers are helpful tools in determining the tumor burden in CTCL and thus might be useful for disease monitoring during treatment. They may have prognostic value for predicting the clinical course.

Abstract
BACKGROUND Patients with follicular lymphoma may survive for periods of less than 1 year to more than 20 years after diagnosis. We used gene-expression profiles of tumor-biopsy specimens obtained at diagnosis to develop a molecular predictor of the length of survival. METHODS Gene-expression profiling was performed on 191 biopsy specimens obtained from patients with untreated follicular lymphoma. Supervised methods were used to discover expression patterns associated with the length of survival in a training set of 95 specimens. A molecular predictor of survival was constructed from these genes and validated in an independent test set of 96 specimens. RESULTS Individual genes that predicted the length of survival were grouped into gene-expression signatures on the basis of their expression in the training set, and two such signatures were used to construct a survival predictor. The two signatures allowed patients with specimens in the test set to be divided into four quartiles with widely disparate median lengths of survival (13.6, 11.1, 10.8, and 3.9 years), independently of clinical prognostic variables. Flow cytometry showed that these signatures reflected gene expression by nonmalignant tumor-infiltrating immune cells. CONCLUSIONS The length of survival among patients with follicular lymphoma correlates with the molecular features of nonmalignant immune cells present in the tumor at diagnosis.
