A population-based cohort study on early-stage Hodgkin lymphoma treated with radiotherapy alone: with special reference to older patients.
BACKGROUND: Combined modality treatment has reduced the risk of relapse among younger early-stage Hodgkin lymphoma (HL) patients. Older HL patients may not tolerate chemotherapy and their prognosis is less favorable. We conducted a population-based study to evaluate long-term follow-up outcome in older early-stage HL patients initially treated with radiotherapy (RT) alone. PATIENTS AND METHODS: We included 308 consecutive patients (22% were >or=60 years) diagnosed 1972-1999 (median follow-up 20 years; range 1-28). Using Cox regression models we defined risk of relapse and survival in relation to clinical factors. RESULTS: 272/308 (88%) patients obtained complete remission following first-line RT alone. Among these, 42% relapsed within a median of 21 months. The relapse rate was independent of gender and age at diagnosis (median age 32 years, range 14-85); however, lymphocyte-predominant HL was associated with borderline (P=0.049) 56% decreased risk of relapse. Among patients<60 years and >or=60 years, we observed 29 (median latency 10 years, range 2-25) and 11 (median latency 3 years, range 1-10) second tumors, respectively. CONCLUSIONS: Older age (>or=60 years) was not associated with an increased risk of relapse following RT alone. Given the risks of iatrogenic morbidity/mortality of chemotherapy in older patients, RT alone could be an alternative first-line therapy in early-stage older HL patients.

Do steroids increase lymphoma risk? A case-control study of lymphoma risk in polymyalgia rheumatica/giant cell arteritis.
BACKGROUND: Recent studies indicate increased risks of malignant lymphomas among individuals treated with corticosteroids, but have not taken into account the underlying reasons for steroid use, so the increased risks might be attributable to the underlying disease or concomitant treatments other than steroids. Polymyalgia rheumatica (PMR) and temporal arteritis (giant cell arteritis, GCA) are common inflammatory conditions treated with steroids as single immunosuppressive therapy, but data on lymphoma risk in GCA/PMR are limited. OBJECTIVE: To assess the risk of lymphoma associated with steroid treatment of GCA/PMR. METHODS: The association between GCA/PMR and malignant lymphomas (overall, and separately for non-Hodgkin lymphoma, Hodgkin lymphoma, and chronic lymphatic leukaemia) was examined in a nationwide, population based, case-control study of 42,676 lymphoma cases and 78,487 matched population controls, using prospectively recorded data on lymphomas from the Swedish cancer register 1964-2000 and data on pre-lymphoma hospital admissions for GCA/PMR from the Swedish inpatient register 1964-2000. Odds ratios (OR) associated with a pre-lymphoma hospital admission for GCA/PMR were calculated using conditional logistic regression. RESULTS: 153 lymphoma cases and 345 population controls had a history of GCA/PMR, resulting in an overall OR for malignant lymphomas of 0.81 (95% confidence interval, 0.67 to 0.98). The OR varied little with lymphoma type, sex, age, and calendar period. The OR for GCA was 0.67 (0.48 to 0.98) and for PMR, 0.83 (0.67 to 1.04). CONCLUSIONS: Treated GCA is not associated with increased lymphoma risks, which suggests that even at considerable cumulative doses, steroids may not appreciably increase lymphoma risk.

Validation of an extended version of the SEIQoL-DW in a cohort of Hodgkin lymphoma' survivors.
Individual measures of quality of life (QoL) have been initiated to overcome the possible limitations with standardized measures using predefined domains for evaluation. The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) uses personal interviews to explore the five most important areas in life, both positive and negative, crucial for QoL. The nominated areas are rated regarding satisfaction and weighted to capture the importance of each selected area. The Swedish version has been extended with a disease-specific module, which evaluates the areas in life influenced by disease. The aim of this study was to validate the disease-specific SEIQoL-DW and furthermore, to evaluate the influence of the importance ratings on the overall index score in a cohort of Hodgkin lymphoma survivors. The results support the construct validity of the disease-specific SEIQoL-DW and indicate that the instrument appears to be a sensitive measure with ability to differentiate between groups with disparate subjective health status. The SEIQoL-DW succeeds to capture both positive and negative areas in life influenced by disease. The present study gave no evidence that the weighting procedure has any impact on the total index. The results support the use of the new extended version including a disease-specific module.

Autologous and allogeneic stem cell transplantation in adult ALL: the Swedish Adult ALL Group experience.
Adult patients with acute lymphoblastic leukaemia (ALL) have been treated according to national protocols in Sweden since 1986. Stem cell transplantation (SCT) has been recommended in first remission for patients with risk factors for relapse, and for standard risk patients only after relapse. In this retrospective study, the results of autologous and allogeneic SCT in these populations were evaluated. In total, 187 patients with a median age of 34 years (17-66 years) underwent SCT. The 5-year disease-free survival (DFS), for all patients, was 26% (Confidence intervals (CI) 20-32%). The 5-year DFS was higher for patients transplanted in first remission 32% (CI 24-40%) compared to 14% (CI 5-23%; P<0.0001) in patients transplanted beyond first remission. No significant differences in DFS (P=0.06) were determined between autologous, related donor and unrelated donor SCT in the whole cohort. A lower relapse rate was counterbalanced by higher treatment-related mortality in patients undergoing allogeneic SCT. In Philadelphia-positive ALL, allogeneic SCT was superior to autologous SCT, with a 5-year DFS of 30% (CI 12-47%) vs 0% (P=0.04). Limited chronic graft-versus-host-disease (GVHD) was associated with an improved DFS of 53% (CI 38-69%) compared to no chronic GVHD of 22% (CI 10-36%; P=0.0008), indicating a clinically important graft-versus-leukaemia effect.

Risk of haematopoietic cancer in patients with inflammatory bowel disease.
BACKGROUND AND AIMS: Several chronic inflammatory conditions are associated with an increased risk of lymphoma. Whether this applies to inflammatory bowel disease (IBD) is still unclear but of paramount interest, particularly in the safety evaluation of newer immunosuppressive drugs. Reports also indicate a possible increase in the risk of leukaemia in IBD. We therefore assessed the risk of haematopoietic cancers in a large cohort of patients with IBD. SUBJECTS AND METHODS: We performed a population based cohort study using prospectively recorded data, including 47 679 Swedish patients with Crohn's disease (CD) or ulcerative colitis (UC) assembled from regional cohorts of IBD from 1955 to 1990 (n = 8028) and from the Inpatient Register of 1964-2000 (n = 45 060), with follow up until 2001. Relative risks were expressed as standardised incidence ratios (SIR). RESULTS: Overall, we observed 264 haematopoietic cancers during follow up, which corresponded to a borderline significant 20% increased risk in both UC and CD. In UC, lymphomas occurred as expected (SIR 1.0, n = 87) but myeloid leukaemia occurred significantly more often than expected (SIR 1.8, n = 32). In CD, there was a borderline significant increased lymphoma risk (SIR 1.3, n = 65), essentially confined to the first years of follow up. Proxy markers of disease activity had little impact on lymphoma risk. CONCLUSION: On average, patients with IBD have a marginally increased risk of haematopoietic cancer. In UC, this is accounted for by an excess of myeloid leukaemia. In CD, a modest short term increase in the risk of lymphoma of unknown significance cannot be excluded but any long term risk increase seems unlikely.

Determinants of health-related quality of life in long-term survivors of Hodgkin's lymphoma.
In this study health-related quality of life (HRQL) in long-term survivors of Hodgkin's lymphoma (HL) was evaluated and the findings were analyzed using a conceptual model developed by Wilson and Cleary. A better understanding of the relationships between the variables explaining HRQL may improve care and rehabilitation of HL patients. The populations were long-term survivors of HL (n = 121) and a control group (n = 236). Participants were approached with one semi-structured interview, an extended version of the Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW) and three standardized questionnaires: Hospital Anxiety and Depression (HAD) scale, Short Form 12 health survey questionnaire (SF-12) and Sense of Coherence (SOC) scale. No differences regarding the mean scores were found between the HL survivors and the controls except for the SF-12, where the patients considered themselves to be in poorer physical health than the controls (p < 0.01). Even though physical health was diminished, patients did not evaluate overall QoL worse compared to the controls. The major determinants of perception of general QoL were self-rated physical and mental health as well as SOC. The HRQL of persons who have survived a median of 14 years with HL is similar to that of controls.

Analysis of minimal residual disease in childhood acute lymphoblastic leukemia: comparison between RQ-PCR analysis of Ig/TcR gene rearrangements and multicolor flow cytometric immunophenotyping.
Detection of minimal residual disease (MRD) in follow-up samples from patients with ALL is essential for evaluation of treatment response. We applied multicolor flow cytometry and real-time quantitative PCR (RQ-PCR) to compare MRD results in 71 follow-up samples from 22 children treated for ALL. When results obtained by flow cytometry and RQ-PCR were grouped into positive-negative categories, a significant level of agreement was found in 72% of samples (P<0.001). However, if a cutoff level of 0.01% was applied, the concordance was 89%. MRD could be quantified in 19 samples by both methods, showing a strong correlation (P<0.01). Nevertheless, MRD levels differed more than five-fold between both methods in 4/19 samples. In 20 (28%) samples, the two techniques showed discordant results. Most discordant results (17/20) were due to the limited sensitivity of flow cytometry analysis within the range 0.01-0.001%; remaining discordant results were due to the instable or subclonal IG/TCR gene rearrangements or a limited quantitative range of the applied RQ-PCR targets. Although concordant results could be obtained by flow cytometry and RQ-PCR analysis, MRD levels may differ. Therefore, MRD data obtained by these two techniques are not yet easily exchangeable.

Granulocyte-macrophage colony-stimulating factor to increase efficacy of mitoxantrone, etoposide and cytarabine in previously untreated elderly patients with acute myeloid leukaemia: a Swedish multicentre randomized trial.
A total of 110 patients, aged 64 years or over, with de novo acute myeloid leukaemia (AML) and white blood cell counts <50 x 109/l were treated with 3 d of cytarabine 1 g/m2 twice daily, mitoxantrone 12 mg/m2 and etoposide 200 mg/m2, randomized with or without the addition of granulocyte-macrophage colony-stimulating factor (GM-CSF) 200 microg/m2. The primary aim was to evaluate the effect of GM-CSF on the remission rate. Secondary aims included comparison of duration of remission, survival and infectious complications and the impact of maintenance therapy with thioguanine. Complete remission (CR) was achieved by 64% of patients without GM-CSF, and by 65% of patients who received GM-CSF, the median remission duration was 13 vs. 6 months, the median overall survival (OS) was 14 vs. 9 months, the mean time to neutrophil recovery was 25 vs. 17 d (P = 0.03) and the number of positive blood cultures was 46 vs. 39 (P = 0.05) respectively. The impact of thioguanine remains unanswered since only 30 patients remained in CR after consolidation therapy. We conclude that induction therapy is feasible with acceptable toxicity in elderly patients with AML, albeit with a high relapse rate and short OS. GM-CSF prior to, and in combination with, induction treatment reduced the time to neutrophil recovery and the number of neutropenic septicaemia cases but did not improve the OS of AML in the elderly.

A prospective study on antibody response to repeated vaccinations with pneumococcal capsular polysaccharide in splenectomized individuals with special reference to Hodgkin's lymphoma.
BACKGROUND: Splenectomy is accompanied by a life-long risk of overwhelming postsplenectomy infection (OPSI), mainly caused by polysaccharide (PS) encapsulated bacteria such as Streptococcus pneumoniae. Despite extensive prophylactic efforts the mortality and morbidity rates remain high. The present study was based on a strategy with a predefined vaccination algorithm including repeated 23-valent pneumococcal vaccinations and monitoring of pneumococcal antibody levels. The antibody levels of splenectomized Hodgkin's lymphoma (HL) patients were compared with those patients splenectomized due to immune-mediated cytopenias [autoimmune haemolytic anaemia (AIHA) and immune thrombocytopenic purpura (ITP)] and also individuals who were splenectomized because of trauma (TRAUMA). METHODS: A total of 311 splenectomized individuals were included in this prospective study (208 HL; 15 AIHA; 60 ITP; 28 TRAUMA). Depending on their individual anti-PS antibody levels measured by enzyme-linked immunosorbent assay technique the patients were revaccinated with 23-valent pneumococcal PS vaccine up to four times in accordance with the predefined algorithm. For each vaccination occasion, serum was collected at vaccination, after 1 month +/- 2 weeks (peak), and after 1 year +/- 6 months (follow-up). Patient files, a national population-based database, and microbiological databases were checked for 124 HL patients to identify OPSI. RESULTS: A significant response was recorded on primary vaccination as well as on two revaccination occasions for HL, AIHA/ITP, as well as TRAUMA patients. None of the variables age, gender, or time elapsed between splenectomy and first pneumococcal vaccination was found to be associated with mean PS antibody levels at prevaccination, peak or follow-up. No severe adverse events were reported. Amongst 124 clinically monitored HL patients, 10 OPSI were recorded in seven patients during the study period. One of these patients, a middle-aged female, died as a result of fulminant pneumococcal bacteraemia, which was her third OPSI during a 7-year period. CONCLUSIONS: A significant response to pneumococcal PS vaccination was found in all three groups (HL, AIHA/ITP and TRAUMA) of splenectomized patients. Importantly, both primary and repeated vaccinations were safe. Until further knowledge is gained regarding the protective concentration of serotype-specific antibody concentrations we believe that the value of vaccination and frequent revaccination (every 1-5 years) in combination with education of patients and health care professionals and clinical monitoring is beneficial for these patients at risk for OPSI.

Individual quality of life in long-term survivors of Hodgkin's lymphoma--a comparative study.
This study aimed to use an individual approach in evaluating QoL in long-term survivors of Hodgkin's lymphoma (HL) and their view of what impact the disease has had on life using an extended version of the The Schedule for the Evaluation of the Individual quality of life-Direct Weighting (SEIQoL-DW). Adult long-term survivors from HL (n = 121) were compared with a randomly selected sample of the general population in Stockholm (n = 236). The results showed that the most commonly nominated areas (> 50% of patients and controls) important in life were family, personal health, work and relations to other people. The HL survivors mentioned leisure and finances less frequently than the controls. However, neither the current status in the different areas nor the QoL index score differed between survivors and controls. Thoughts and worries around disease, fatigue and loss of energy and late effects on skin and mucous membrane were the most commonly reported problems following HL. Sixty-six percent of the survivors reported a change in their view of life and of themselves. Demographic and disease characteristics did not influence the ratings of the chosen areas. In conclusion, long-term survivors of HL seem to have adapted well to the situation of having had a life-threatening disease and undergoing treatment, as measured with SEIQoL-DW. The extended Swedish version with a disease-specific module could be of great value when identifying specific issues that are important for the patient at time of evaluation.

No benefit from adding GM-CSF to induction chemotherapy in transforming myelodysplastic syndromes: better outcome in patients with less proliferative disease.
In this prospective randomized multicenter trial 93 patients, median age 72 years, with RAEB-t (n=25) and myelodysplastic syndrome (MDS)-AML (n=68) were allocated to a standard induction chemotherapy regimen (TAD 2+7) with or without addition of granulocyte-macrophage-CSF (GM-CSF). The overall complete remission (CR) rate was 43% with no difference between the arms. Median survival times for all patients, CR patients, and non-CR patients were 280, 550, and 100 days, respectively, with no difference between the arms. Response rates were significantly better in patients with serum lactate dehydrogenase (S-LDH) levels </=9.5 microkat/l, bone marrow cellularity </=70%, and WBC counts <4.0 x 10(9)/l, but S-LDH was the only variable independently associated with response by logistic regression analysis. Cox's regression analysis identified four significant prognostic factors for survival: bone marrow cellularity, S-LDH, cytogenetic risk group (International Prognostic Scoring System), and age. Only bone marrow cellularity (P=0.01) and S-LDH (P=0.0003) retained statistical significance in the log-rank test. Severe adverse events were significantly more common in the GM-TAD arm (P=0.01). Thus, addition of GM-CSF to chemotherapy showed no clinical benefit in terms of response but carried an increased risk for side effects. We present a clinically useful tool to predict response to chemotherapy and survival in elderly patients with transforming MDS, favoring patients with features of less proliferative disease.

Patterns of clinical presentation, treatment, and outcome in patients with Waldenstrom's macroglobulinemia: a two-institution study.
Waldenstrom's macroglobulinemia (WM) is in the World Health Organization (WHO) classification considered to be a clinical syndrome rather than a specific pathologic diagnosis. The clinical manifestations associated with WM relate to direct tumor infiltration, hyperviscosity, and deposition of IgM in various tissues. The indications for and choice of treatment vary considerably and no generally accepted prognostic models exist. The clinical features, treatment, and prognosis of 72 patients with WM seen at one British (n = 36) and one Swedish (n = 36) academic center were therefore compared. Significantly more patients presented with a low albumin concentration (< v > 40 g/L, P <.001), anemia (hemoglobin < v > 120 g/L; P <.001), thrombocytopenia (< v > 150 x 10(9)/L; P <.05), hepatomegaly (P <.001), splenomegaly (P <.01), and lymphadenopathy (P <.01), at St Bartholomew's Hospital (SBH) in comparison to the Karolinska Hospital (KH). Fifty-six percent of SBH patients received chemotherapy immediately following diagnosis as compared to 14% at KH. The median overall survival of all patients was 6.3 years; 4.2 years and 11.0 years at SBH and KH, respectively (P <.001). In univariate analysis, anemia (hemoglobin < 120 g/L) and albumin < 35 g/L (but not <40 g/L) at diagnosis predicted a worse overall survival. The presence of hepatomegaly and/or splenomegaly and/or lymphadenopathy was significantly associated with anemia (P <.001) and hypoalbuminaemia (P <.001). The mean Morel score (including age, albumin, and cytopenias) of patients treated at SBH (2.6) was significantly higher than that of KH patients (1.6; P <.001). These findings illustrate the clinical heterogeneity of WM, most probably explained by differences in referral patterns, and in addition, indicate the need for establishing standard criteria for diagnosis, response to treatment, and prognostic features.

Long-term follow-up of patients >or=60 yr old with acute myeloid leukaemia treated with intensive chemotherapy.
It is still controversial how to treat elderly patients with acute myeloid leukaemia (AML), and results have been poor with most regimens. We report the long-term results of a randomised study performed by the Leukaemia Group of Middle Sweden during 1984-88 comparing two intensive chemotherapeutic drug combinations. Ninety patients >or=60-yr old with untreated AML were randomly allocated to treatment with daunorubicin, cytosine arabinoside (ara-C), and thioguanine (TAD) (43 patients) or a combination in which aclarubicin was substituted for daunorubicin (TAA) (47 patients). Forty-four patients (49%) entered complete remission (CR), 22/43 (51%) in the TAD group and 22/47 (47%) in the TAA group (ns). The CR rate in patients 70 yr 14/48 (29%) (P<0.0001). Early death within 30 d after treatment initiation was more often seen in patients >70 yr than in patients or=10 yr after inclusion of the last patient, 5/90 patients (one in the TAD group and four in the TAA group, respectively) were still alive, four in continuous complete remission and one in second complete remission. Thus, both treatment regimens appear to have similar efficacy, with a relatively high complete remission rate, and a reasonable survival as compared to other studies including some long-term survivors. However, early deaths are still numerous, particularly in patients above 70 yr of age, and the relapse rate is substantial.

Early response to chemotherapy: a surrogate for final outcome of Hodgkin's disease patients that should influence initial treatment length and intensity?
BACKGROUND: Early adjustment of treatment may benefit the patient. In order to guide treatment adjustment, use of early response (ER) or early complete response (ECR), judged after the few initial cycles of chemotherapy, is common in pediatric and also adult Hodgkin's and non-Hodgkin's studies. Paradoxically, almost no data support this strategy. PATIENTS AND METHODS: The influence of ECR on outcome was evaluated in three series of advanced Hodgkin's disease (HD), leading to a series of questions. RESULTS: The 1982 EORTC study assessed prospectively the time frame needed to reach an apparent complete response (CR) through repeated tumor measurements. In patients assessed at mid-treatment before the fifth cycle, both 15 year freedom from progression (FFP) and overall survival (OS) were superior in ECR patients compared with other patients continued on the same treatment (61% versus 37%; P < 0.001). A series of questions arise from these observations. Question 1: is the shortening of treatment detrimental? In a randomized Swedish trial, in one arm treatment was shortened in patients evaluated from the fifth cycle as ECR as compared with the standard eight cycles arm, 10 year cause-specific-survival (CSS) was 53 versus 69% [not significant (ns)]; 10 year OS 49% versus 58% (ns). Conversely, in the EORTC 20884 study, ECR patients given only six cycles did as well as patients entering CR later and, for this reason, given eight cycles (identical 6 year event-free survival 75%). Question 2: is early treatment adaptation in patients who failed to reach ER beneficial? In the French MDH 90 trial, 15% of children failed to reach ECR after four cycles; in these children only, anthracyclines plus alkylating agents were given and the dose of radiotherapy increased, improving the results observed in the previous trial. In the EORTC 20884 study, patients who failed to reach an ECR were switched earlier to involved field RT: their results matched those of ECR patients, at the difference of the previous trial. Question 3: is ER a predicting factor that can be used with any type of treatment? Probably not, based on the German Hodgkin's Lymphoma Study Group trial HD 9: ECR is highly dependent on specific interval from treatment start and on treatment intensity. DISCUSSION: More general questions stem from these results. Question 4: is the definition of ER secured? With conventional imaging, the different methods for response assessment at end treatment also lead to different response rates; the assessment in the middle of treatment itself and the use of newer imaging techniques may further increase the variation. Indeed, question 5 is: is ER a concept based on any biology? Correlation to markers, 99mTc uptake, PET and hematological tolerance might help to pinpoint how and why ER represents a surrogate for final outcome. CONCLUSION: ER is a surrogate for final outcome, reflecting both tumor burden and activity. This predictability may, and possibly should, impact on treatment.

Negligible clinical effects of thalidomide in patients with myelofibrosis with myeloid metaplasia.
We conducted a nonrandomized prospective phase II study of thalidomide in anemic patients with myelofibrosis with myeloid metaplasia (MMM), with or without preceding polycythemia vera or essential thrombocythemia, with a primary aim to improve anemia. Thalidomide was given in escalating doses with a target dose of 800 mg daily, but the median dose of thalidomide that was actually tolerated was 400 mg daily. Fifteen patients were entered into the study and 14 were evaluable for response. Five of 14 (36%) patients discontinued thalidomide before 3 mo because of side effects, and none of these five patients had a response at the time when thalidomide was stopped. When evaluated after 3 mo of therapy, none of the remaining nine patients exhibited a discernible clinical response. Three patients showed progressive disease defined as > 50% increase in the need for red cell transfusions. Treatment was poorly tolerated, with all patients reporting side effects of thalidomide, the most prominent being fatigue documented in 80% of patients. Two patients died while on study, one from acute myelogenous leukemia and one from pneumonia. We conclude that thalidomide given in doses employed in the treatment of multiple myeloma gives no clinically relevant hematological effects in advanced MMM and is hampered by a very high incidence of side effects.

Interleukin-10 gene promoter polymorphisms in multiple myeloma.
Multiple myeloma (MM) is a B-cell malignancy characterized by an accumulation of malignant plasma cells in the bone marrow. It is unclear whether genetic background could have an etiological impact on MM or influence the course of the disease. Interleukin-10 (IL-10) has been implicated in the growth and differentiation of normal B cells, and has also been shown to enhance the proliferation of MM cells. To address the putative involvement of IL-10 genetic variation in MM, we analyzed previously defined loci for bi-allelic polymorphism at position -1082 and two microsatellite loci (IL10.G and IL10.R) in the IL-10 promoter region. Seventy-three patients with MM, 27 with monoclonal gammopathy of undetermined significance, and 109 ethnically matched individuals as controls were included in the study. Significantly increased frequencies of the IL10.G genotype 136/136 and the IL10.R genotype 112/114, in addition to a decreased frequency of the IL10.R genotype 114/116, were found among the MM patients. Increased production of IL-10 was detected in the supernatants of lipopolysaccharide-stimulated peripheral blood mononuclear cells from MM patients who were homozygotes (136/136) and heterozygotes (136/non-136) for the IL10.G allele 136, as compared with the other IL10.G genotype carriers (non-136/non-136). These results suggest that the genetic variation in the IL-10 promoter region may play a role in the development of MM.
