PATIENTS AND METHODS: Follicle-stimulating hormone (FSH) levels were measured in patients with early-stage upper-diaphragmatic disease enrolled in four European Organisation for Research and Treatment of Cancer (EORTC) trials (H6-H9). Median follow-up after therapy was 32 months. Patients with FSH measurement at least 12 months after end of treatment (n = 355) were selected to assess post-treatment fertility. Patients with FSH measurement 0 to 9 months after therapy (n = 349) were selected to analyze fertility recovery; of these, patients with elevated FSH (> 10 U/L; n = 101) were followed until recovery. Factors predictive for therapy-related infertility were assessed by logistic regression. RESULTS: The proportion of elevated FSH was 3% and 8% in patients treated with radiotherapy only or with nonalkylating chemotherapy (doxorubicin, bleomycin, vinblastine, dacarbazine [ABVD], epirubicin, bleomycin, vinblastine, prednisone [EBVP]); it was 60% (P < .001) after chemotherapy containing alkylating agents (mechlorethamine, vincristine, procarbazine, prednisone [MOPP], MOPP/doxorubicin, bleomycin, vinblastine [ABV], bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone [BEACOPP]). After a median time of 19 months, recovery of fertility occurred in 82% of patients treated without alkylating chemotherapy. This proportion was 30%, statistically (P < .001) lower in those treated with alkylating chemotherapy, and median time to recovery was 27 months. The post-treatment proportion of elevated FSH increased significantly (P < .001) with the dose of alkylating chemotherapy administered, and recovery was less frequent and slower after higher doses. Age more than 50 years and stage II disease also contributed to poor outcome. CONCLUSION: Fertility can be secured after nonalkylating chemotherapy for Hodgkin's lymphoma. In contrast, alkylating chemotherapy has a dismal effect, even after a limited number of cycles

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 lymphom

Long-Term Outcome of Patients With a Hematologic Malignancy and Multiple Organ Failure Admitted at the Intensive Care

Objectives: Historically, patients with a hematologic malignancy have one of the highest mortality rates among cancer patients admitted to the ICU. Therefore, physicians are often reluctant to admit these patients to the ICU. The aim of our study was to examine the survival of patients who have a hematologic malignancy and multiple organ failure admitted to the ICU. Design: This retrospective cohort study, part of the HEMA-ICU study group, was designed to study the survival of patients with a hematologic malignancy and organ failure after admission to the ICU. Patients were followed for at least 1 year. Setting: Five university hospitals in the Netherlands. Patients: One-thousand ninety-seven patients with a hematologic malignancy who were admitted at the ICU. Interventions: None. Measurements and Main Results: Primary outcome was 1-year survival. Organ failure was categorized as acute kidney injury, respiratory failure, hepatic failure, and hemodynamic failure; multiple organ failure was defined as failure of two or more organs. The World Health Organization performance score measured 3 months after discharge from the ICU was used as a measure of functional outcome. The 1-year survival rate among these patients was 38%. Multiple organ failure was inversely associated with long-term survival, and an absence of respiratory failure was the strongest predictor of 1-year survival. The survival rate among patients with 2, 3, and 4 failing organs was 27%, 22%, and 8%, respectively. Among all surviving patients for which World Health Organization scores were available, 39% had a World Health Organization performance score of 0–1 3 months after ICU discharge. Functional outcome was not associated with the number of failing organs. Conclusions: Our results suggest that multiple organ failure should not be used as a criterion for excluding a patient with a hematologic malignancy from admission to the ICU

Morbidity and mortality in adults with idiopathic thrombocytopenic purpura

To study outcomes of adults with idiopathic thrombocytopenic purpura (ITP), we performed a follow-up study in a cohort of 152 consecutive patients who were treated according to a well-defined algorithm. Long-term outcomes were determined relative to the response 2 years after diagnosis, be cause most (93%) patients who ultimately attained platelet counts above 30.0 x 10(9)/L (30 000/muL) did so within this time frame. Complete follow-up for mortality could be studied in 99% of patients and for morbidity in 95% of patients,with a mean of 10.5 years. Within 2 years after diagnosis, 4 patients died, 2 were lost to follow-up, and 12 were reclassified as having secondary immune thrombocytopenia. Of the remaining 134 patients, 114 (85%) had obtained platelet counts above 30.0 x 10(9)/L while all therapies had been discontinued. These patients had a long-term mortality risk equal to the general population. Twelve of 134 patients (9%), all with severe thrombocytopenia, had refractory disease and suffered a mortality risk of 4.2 (95% confidence interval, 1.7-10.0). Bleeding and infection equally contributed to the death of these patients. Another 8 patients (6%) had platelet counts above 30.0 x 10(9)/L while on maintenance therapy. Similar to patients with refractory disease, these latter patients had considerably increased ITP-related hospital admissions, but mortality was only slightly higher than in the general population. In conclusion, most adults with ITP have a good outcome with infrequent hospital admissions and no excess mortality. The absence of gross morbidity and mortality in patients with moderate thrombocytopenia supports clinical practice refraining from further treatment.

Monitoring of engraftment and progression of acute lymphoblastic leukemia in individual NOD/SCID mice

Objective. The aim of this study was to develop an animal model for human acute lymphoblastic leukemia (ALL) in which the kinetics and characteristics of leukemia can be sequentially monitored in individual mice. Materials and Methods. NOD/SCID mice were inoculated intravenously with primary ALL. Progression of leukemia was monitored throughout the development of disease by determination of absolute leukemic cell counts (LCC) in peripheral blood. Results. LCC as low as 10(4) leukemic cells/mL blood could be detected. ALL cells from 5 of 5 patients engrafted, and after identification of the first leukemic cells in peripheral blood, LCC increased exponentially. Leukemic cells showed specificity of homing to spleen and bone marrow, and LCC strongly correlated with the level of leukemic engraftment in these organs throughout disease progression, demonstrating that LCC are representative for overall leukemic burden. Cytogenetic analysis of leukemic cells recovered after six successive in vivo transfers revealed no major karyotypic changes as compared to primary cells, and selection of the dominant clones was observed. This selection process was reflected by an increase in the rate of leukemic progression as compared to the first inoculation, demonstrating the accuracy with which kinetics of leukemic progression can be studied by determination of LCC, Conclusions. This model is suitable for detailed studies of kinetics and characteristics of ALL in vivo, and it may be useful for monitoring effects of novel therapeutic regimens.

Elevated albuminuria associated with increased risk of recurrent venous thromboembolism: results of a population-based cohort study

This study examined the risk of recurrent venous thromboembolism (VTE) in patients with elevated albuminuria. In 1997-1998, inhabitants of Groningen, the Netherlands, aged 28-75 years (n = 85 421), were invited to participate in the PREVEND(Prevention of REnal and Vascular ENd stage Disease) Study, an observational, population-based cohort study. Albuminuria was measured and VTE occurrence was monitored in responding subjects (n = 40 856). Patients with first VTE between study entry and January 2009, identified through databases of the national registry of hospital discharge diagnoses, death certificates, regional anticoagulation clinic and medical records, were used for analysis. Of 351 subjects with first VTE, 37 subjects developed a recurrence during a median follow-up period of 3.3 (interquartile range, 1.1-6.4) years. The annual incidence of recurrence in subjects with elevated albuminuria (>= 20 mg/l) was 5.00% [95% confidence interval (CI); 2.16-9.85], compared to 2.38% (95% CI; 1.59-3.41) in subjects with normal albuminuria (<20 mg/l). Hazard ratio for recurrence was 1.95 (95% CI; 0.89-4.30) after adjustment for age and sex. This hazard ratio was 3.35 (95% CI; 1.18-9.47) in patients with first unprovoked, and 1.12 (95% CI; 0.25-5.01) in those with a first provoked event. This study showed that subjects with elevated albuminuria who experience an unprovoked VTE are at an increased risk of recurrence, independent of age and sex
