Health-related quality of life after chemotherapy with or without rituximab in primary central nervous system lymphoma patients: results from a randomised phase III study.

BACKGROUND: The impact of rituximab on health-related quality of life (HRQoL) in primary central nervous system lymphoma patients is not well known. We determined the impact of rituximab added to standard high-dose methotrexate-based treatment on HRQoL in patients in a large randomised trial. PATIENTS AND METHODS: Patients from a large phase III trial (HOVON 105/ALLG NHL 24), randomly assigned to receive standard chemotherapy with or without rituximab and followed by 30 Gy whole brain radiotherapy (WBRT) in patients ≤60 years, completed the EORTC QLQ-C30 and QLQ-BN20 questionnaires before and during treatment, and up to 24 months of follow-up or progression. Differences between treatment arms over time in global health status, role functioning, social functioning, fatigue, and motor dysfunction were assessed. Differences ≥10 points were deemed clinically relevant. The effect of WBRT on HRQoL was analysed in irradiated patients. RESULTS: A total of 160/175 patients eligible for the HRQoL study completed at least one questionnaire and were included. Over time, scores improved statistically significantly and were clinically relevant in both arms. Between arms, there were no differences on any scale (range: -3.8 to +4.0). Scores on all scales were improved to a clinically relevant extent at 12 and 24 months compared with baseline in both arms, except for fatigue and motor dysfunction at 12 months (-7.4 and -8.8, respectively). In irradiated patients (n = 59), scores in all preselected scales, except motor dysfunction, remained stable up to 24 months compared with shortly after WBRT, overall mean difference ranging between 0.02 and 4.570. CONCLUSION: Compared with baseline, treatment resulted in improved HRQoL scores. The addition of rituximab to standard chemotherapy did not impact HRQoL over time. WBRT did not result in deterioration of HRQoL in the first 2 years.

Epstein-Barr virus infection or malignant lymphoma - what you see is not what you get.

Infectious mononucleosis may mimic lymphoma, both clinically and histopathologically. We present a patient with neurological symptoms and lymphadenopathy, initially diagnosed as Epstein-Barr virus (EBV)-positive angioimmunoblastic T-cell lymphoma (AITL) with cerebrospinal fluid (CSF) localisation based on lymph node pathology and a 30-fold higher EBV load in the CSF compared with serum. However, the patient fully recovered spontaneously and EBV became negative in both CSF and serum, suggestive of a dramatic presentation of EBV meningoencephalitis.

A longitudinal and cross-sectional study ofEpstein-Barr virus DNA load: a possible predictor of AIDS-related lymphoma in HIV-infected patients.

INTRODUCTION: HIV-infected patients are more than 100-fold greater at risk for developing malignant AIDS-related lymphoma (ARL) compared to the general population. Most ARLs are EBV related. The main purpose of this study was to investigate whether a high peak EBV DNA load in HIV-infected patients is predictive of ARL, including classical Hodgkin lymphoma. METHODS: From an ongoing prospective HIV positive cohort study, we conducted a case-control study between 2004 and 2016 among patients from whom at least one EBV DNA load in serum or plasma was available. We compared peak EBV DNA load between patients with (49 cases) and without ARL (156 controls). RESULTS: The geometric mean of the peak EBV DNA load measured before diagnosis of malignant lymphoma was 52,565 IU/mL in EBER-positive lymphoma patients vs. 127 IU/mL in controls (p < .001). Patients with EBV DNA loads >100,000 IU/mL have an increased risk for diagnosis of malignant lymphoma compared to patients with EBV DNA loads ≤100,000 IU/mL (adjusted OR 12.53; 95%CI: 4.08; 38.42). In the longitudinal study, including 13 patients with at least three left-over plasma samples available for retesting, measurements of EBV-DNA during the preceding 12 months proved to be of poor value for predicting subsequent lymphoma diagnosis. CONCLUSIONS: A EBV DNA load >100,000 IU/mL can be useful in clinical setting to accelerate time to diagnosis and treatment. EBV-DNA loads in samples taken during the preceding year of ARL diagnosis showed to be of poor predictive value.

Efficacy of intrathecal chemotherapy in patients with central nervous system involvement of hematological malignancies: a retrospective analysis.

INTRODUCTION: Central nervous system (CNS) involvement, especially involvement of the cerebrospinal fluid (CSF), is common in several haematological malignancies. Intrathecal (IT) chemotherapy can be used to manage CSF involvement. METHODS: Here we evaluated the effectiveness of IT chemotherapy among 80 patients with haematological malignancies and CSF localization who were treated with IT chemotherapy from 2001 to 2012. RESULTS: The majority of patients was diagnosed with diffuse large B-cell lymphoma (26%) or acute lymphoblastic leukaemia/lymphoblastic lymphoma (19%). After first-line IT chemotherapy, which mainly consisted of methotrexate (MTX) and corticosteroids, CSF complete response (CSF CR) was achieved in 76% of patients. 91% reached CSF CR when including second-line IT-chemotherapy. Clinical response was documented in 75%. Although most patients were additionally treated with systemic chemotherapy, response rate did not differ between patients treated with CNS-penetrating and CNS-non-penetrating drugs. CNS progression/relapse occurred in 40% of patients with median progression-free survival of 12.2 months. The median overall survival was 18.3 months; 55% of the patients died during follow-up. CONCLUSIONS: Our analysis shows a high response rate after first-line IT chemotherapy, but also a relatively high progression/relapse percentage.

Treatment of sporadic Burkitt lymphoma in adults, a retrospective comparison of four treatment regimens.

Burkitt lymphoma is an aggressive B cell malignancy accounting for 1-2% of all adult lymphomas. Treatment with dose-intensive, multi-agent chemotherapy is effective but associated with considerable toxicity. In this observational study, we compared real-world efficacy, toxicity, and costs of four frequently employed treatment strategies for Burkitt lymphoma: the Lymphome Malins B (LMB), the Berlin-Frankfurt-Münster (BFM), the HOVON, and the CODOX-M/IVAC regimens. We collected data from 147 adult patients treated in eight referral centers. Following central pathology assessment, 105 of these cases were accepted as Burkitt lymphoma, resulting in the following treatment groups: LMB 36 patients, BFM 19 patients, HOVON 29 patients, and CODOX-M/IVAC 21 patients (median age 39 years, range 14-74; mean duration of follow-up 47 months). There was no significant difference between age, sex ratio, disease stage, or percentage HIV-positive patients between the treatment groups. Five-year progression-free survival (69%, p = 0.966) and 5-year overall survival (69%, p = 0.981) were comparable for all treatment groups. Treatment-related toxicity was also comparable with only hepatotoxicity seen more frequently in the CODOX/M-IVAC group (p = 0.004). Costs were determined by the number of rituximab gifts and the number of inpatients days. Overall, CODOX-M/IVAC had the most beneficial profile with regards to costs, treatment duration, and percentage of patients completing planned treatment. We conclude that the four treatment protocols for Burkitt lymphoma yield nearly identical results with regards to efficacy and safety but differ in treatment duration and costs. These differences may help guide future choice of treatment.

Cryopreservation, semen use and the likelihood of fatherhood in male Hodgkin lymphoma survivors: an EORTC-GELA Lymphoma Group cohort study.

STUDY QUESTION: How does the successful cryopreservation of semen affect the odds of post-treatment fatherhood among Hodgkin lymphoma (HL) survivors? SUMMARY ANSWER: Among 334 survivors who wanted to have children, the availability of cryopreserved semen doubled the odds of post-treatment fatherhood. WHAT IS KNOWN ALREADY: Cryopreservation of semen is the easiest, safest and most accessible way to safeguard fertility in male patients facing cancer treatment. Little is known about what proportion of patients achieve successful semen cryopreservation. To our knowledge, neither the factors which influence the occurrence of semen cryopreservation nor the rates of fatherhood after semen has been cryopreserved have been analysed before. STUDY DESIGN, SIZE, DURATION: This is a cohort study with nested case-control analyses of consecutive Hodgkin survivors treated between 1974 and 2004 in multi-centre randomized controlled trials. A written questionnaire was developed and sent to 1849 male survivors. PARTICIPANTS/MATERIALS, SETTING, METHODS: Nine hundred and two survivors provided analysable answers. The median age at treatment was 31 years. The median follow-up after cryopreservation was 13 years (range 5-36). MAIN RESULTS AND THE ROLE OF CHANCE: Three hundred and sixty-three out of 902 men (40%) cryopreserved semen before the start of potentially gonadotoxic treatment. The likelihood of semen cryopreservation was influenced by age, treatment period, disease stage, treatment modality and education level. Seventy eight of 363 men (21%) used their cryopreserved semen. Men treated between 1994 and 2004 had significantly lower odds of cryopreserved semen use compared with those treated earlier, whereas alkylating or second-line (chemo)therapy significantly increased the odds of use; no other influencing factors were identified. We found an adjusted odds ratio of 2.03 (95% confidence interval 1.11-3.73, P = 0.02) for post-treatment fatherhood if semen cryopreservation was performed. Forty-eight out of 258 men (19%) who had children after HL treatment became a father using cryopreserved semen. LIMITATIONS, REASONS FOR CAUTION: Data came from questionnaires and so this study potentially suffers from response bias. We could not perform an analysis with correction for duration of follow-up or provide an actuarial use rate due to lack of dates of semen utilization. We do not have detailed information on either the techniques used in cryopreserved semen utilization or the number of cycles needed. STUDY FUNDING/COMPETING INTERESTS: Lance Armstrong Foundation, Dutch Cancer Foundation, René Vogels Stichting, no competing interests.

Treatment of older patients with mantle-cell lymphoma.

BACKGROUND: The long-term prognosis for older patients with mantle-cell lymphoma is poor. Chemoimmunotherapy results in low rates of complete remission, and most patients have a relapse. We investigated whether a fludarabine-containing induction regimen improved the complete-remission rate and whether maintenance therapy with rituximab prolonged remission. METHODS: We randomly assigned patients 60 years of age or older with mantle-cell lymphoma, stage II to IV, who were not eligible for high-dose therapy to six cycles of rituximab, fludarabine, and cyclophosphamide (R-FC) every 28 days or to eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 21 days. Patients who had a response underwent a second randomization to maintenance therapy with rituximab or interferon alfa, each given until progression. RESULTS: Of the 560 patients enrolled, 532 were included in the intention-to-treat analysis for response, and 485 in the primary analysis for response. The median age was 70 years. Although complete-remission rates were similar with R-FC and R-CHOP (40% and 34%, respectively; P=0.10), progressive disease was more frequent with R-FC (14%, vs. 5% with R-CHOP). Overall survival was significantly shorter with R-FC than with R-CHOP (4-year survival rate, 47% vs. 62%; P=0.005), and more patients in the R-FC group died during the first remission (10% vs. 4%). Hematologic toxic effects occurred more frequently in the R-FC group than in the R-CHOP group, but the frequency of grade 3 or 4 infections was balanced (17% and 14%, respectively). In 274 of the 316 patients who were randomly assigned to maintenance therapy, rituximab reduced the risk of progression or death by 45% (in remission after 4 years, 58%, vs. 29% with interferon alfa; hazard ratio for progression or death, 0.55; 95% confidence interval, 0.36 to 0.87; P=0.01). Among patients who had a response to R-CHOP, maintenance therapy with rituximab significantly improved overall survival (4-year survival rate, 87%, vs. 63% with interferon alfa; P=0.005). CONCLUSIONS: R-CHOP induction followed by maintenance therapy with rituximab is effective for older patients with mantle-cell lymphoma.

Repetitive dobutamine stress echocardiography for the prediction of anthracycline cardiotoxicity.

AIMS: To evaluate whether repetitive assessment of systolic and diastolic cardiac function by dobutamine stress echocardiography (DSE) can predict anthracycline cardiotoxicity. METHODS AND RESULTS: Thirty-one patients (age, 57+/-13 years, 22 male) were studied before chemotherapy, with follow-ups during, at the end, and 6 months after chemotherapy. Left ventricular (LV) function was assessed by two-dimensional (2D) echocardiographic wall motion score index (WMSI) and by Doppler echocardiography of mitral valve inflow at rest and during DSE. Radionuclide ventriculography was used as an independent reference for ejection fraction (EF). A reduction of EF >/=5% occurred in 17 patients (group A) at the last follow-up. Patients without decreased EF comprised group B. Early/late diastolic velocity of mitral inflow (E/A ratio) at rest was lower in group A (0.91+/-0.2 vs 1.28+/-0.3, P<0.001), and it was an independent predictor of cardiotoxicity (adjusted for baseline patient characteristics and parameters of systolic and diastolic function). At follow-up, WMSI at rest paralleled radionuclide EF. Contractile reserve at low-dose DSE was preserved in group A. CONCLUSIONS: WMSI measured by 2D echocardiography parallels radionuclide EF at follow-up. Assessment of contractile reserve has no incremental value for the early detection of cardiotoxicity. A baseline abnormal E/A ratio is an independent predictor of anthracycline cardiotoxicity.

CHOP compared with CHOP plus granulocyte colony-stimulating factor in elderly patients with aggressive non-Hodgkin's lymphoma.

PURPOSE: To investigate whether the relative dose-intensity of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy could be improved by prophylactic administration of granulocyte colony-stimulating factor (G-CSF) in elderly patients with aggressive non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Patients aged 65 to 90 years (median, 72 years) with stage II to IV aggressive NHL were randomly assigned to receive standard CHOP every 3 weeks or CHOP plus G-CSF every 3 weeks on days 2 to 11 of each cycle. RESULTS: In 389 eligible patients, the relative dose intensities (RDIs) of cyclophosphamide (median, 96.3% v 93.9%; P =.01) and doxorubicin (median, 95.4% v 93.3%; P =.04) were higher in patients treated with CHOP plus G-CSF. The complete response rates were 55% and 52% for CHOP and CHOP plus G-CSF, respectively (P =.63). The actuarial overall survival at 5 years was 22% with CHOP alone, compared with 24% with CHOP plus G-CSF (P =.76), with a median follow-up of 33 months. Patients treated with CHOP plus G-CSF had an identical incidence of infections, with World Health Organization grade 3 to 4 (34 of 1,191 cycles v 36 of 1,195 cycles). Only the cumulative days with antibiotics were fewer with CHOP plus G-CSF (median, 0 v 6 days; P =.006) than with CHOP alone. The number of hospital admissions and the number of days in hospital were not different. CONCLUSION: In elderly patients, G-CSF improved the RDI of CHOP, but this did not lead to a higher complete response rate or better overall survival. G-CSF did not prevent serious infections.

[Lamivudine for the prevention of chronic hepatitis B exacerbations during chemotherapy for non-Hodgkin's lymphoma]. / Lamivudine ter voorkoming van opvlamming van chronische hepatitis B tijdens chemotherapie voor non-Hodgkin-lymfoom.

Two male patients, aged 54 years and 17 years respectively, were treated with chemotherapy for non-Hodgkin lymphoma. Both patients were chronic hepatitis-B-virus (HBV) carriers prior to the chemotherapy. One patients died as a result of the virus exacerbating during chemotherapy; the other patient received the antiviral drug lamivudine prior to the chemotherapy and finished the cures without any problems. Exacerbations of HBV replication followed by an increase in serum transaminase activity levels ('flares') occur naturally during the course of the viral infection. However, there is an elevated risk when a patient receives high doses of corticosteroids for a short period, as is the case in chemotherapy for non-Hodgkin's lymphoma. Lamivudine is registered for the treatment of chronic hepatitis B and can be used as a prophylactic prior to chemotherapy or to treat an exacerbation of the hepatitis. It is advisable to systematically test all patients with lymphoma for the presence of the HBsAg. If this is positive, prophylactic administration of lamivudine 100 mg once daily is strongly recommended if chemotherapy is indicated.

Etoposide, mitoxantrone and prednisone: a salvage regimen with low toxicity for refractory or relapsed non-Hodgkin's lymphoma.

BACKGROUND AND OBJECTIVES: Relapsed non-Hodgkin's lymphoma (NHL) is preferably treated with high-dose therapy and stem cell support. However, not all patients qualify for intensive chemotherapy. We evaluated the efficacy and toxicity of a new salvage chemotherapy regimen designed for patients with relapsed or refractory NHL who are not appropriate candidates for high-dose therapy (HDT). DESIGN AND METHODS: Seventy-nine patients received a regimen consisting of etoposide (350 mg/m(2) i.v. day 1), mitoxantrone (14 mg/m(2) i.v. day 1) and prednisone (80 mg/m(2) p.o. days 1-5) (EMP). The majority had aggressive NHL. Twenty-one patients were elderly, i.e. >60 years of age; RESULTS: The overall response rate in the 79 patients was 38% as compared to 67% in the elderly. The progression-free survival was 54% and 30% at 12 months and 24 months, respectively. The toxicity of the regimen was relatively low. No toxic deaths have occurred. In 28 of 231 cycles (12%) a CTC-grade 2-4 infection was encountered. Twenty-one hospital admissions were necessary because of infection or fever. Other toxicity was rare. Toxicity was not greater in the elderly patients. WHO performance status 2-4 and elevated serum lactate dehydrogenase (LDH) concentrationv were adverse prognostic factors for response as well as for overall survival. Another adverse prognostic factor for response was age <60 years. INTERPRETATION AND CONCLUSIONS: EMP is a new salvage regimen with a relatively low toxicity. It should be considered for patients with relapsed or refractory NHL who are not candidates for standard reinduction therapy and stem cell transplantation.

[Diagnosis and treatment of non-Hodgkin lymphoma in elderly patients]. / Diagnostiek en behandeling van het non-Hodgkin-lymfoom bij de oudere patiënt.

Non-Hodgkin's lymphoma (NHL) is relatively frequent among elderly patients: more than half of the diagnoses in the Netherlands concern patients aged 65 years or above. The treatment depends on histological type, clinical stage and prognostic group. Increasingly, a treatment decision is made after determination of the prognostic group on the basis of the expected response and survival. In elderly patients intensive treatment frequently has more toxic effects. The expected gain in survival has to be weighed against more toxicity and loss of quality of life during and after the therapy. This is notably important for patients with low grade NHL, which requires only intermittent treatment. It is possible to cure some elderly patients with NHL of intermediate or high grade malignancy provided they are adequately treated with combination chemotherapy. Patients with low grade NHL or poor clinical condition may benefit temporarily from palliative treatment, in the planning of which quality of life has to be taken into account.

Eosinophilia and granulocytic dysplasia terminating in acute myeloid leukaemia after 24 years.

Eosinophilia of variable duration, and subsequent progression to granulocytic sarcoma and acute myeloid leukaemia, has been infrequently reported in the literature. We report a patient with eosinophilia and normal cytogenetics who, after 24 years, showed transformation to a granulocytic sarcoma of the brain. Haematological counts were normal but the marrow revealed the cytogenetic abnormality trisomy 8 in 25% of mitoses. Subsequently an AML-M2 developed, showing a complex karyotype including the trisomy 8 in all metaphases. FISH analysis combined with cytological examination identified the trisomy 8 in blasts, eosinophils and dysplastic granulocytes only. Thus progressive leukaemic transformation selectively involved the myeloid compartment.
