A Randomized, Controlled Trial of Prophylactic Ganciclovir for Cytomegalovirus Pulmonary Infection in Recipients of Allogeneic Bone Marrow Transplants

Abstract Background. Cytomegalovirus (CMV)-associated interstitial pneumonia is a major cause of death after allogeneic bone marrow transplantation. We conducted a controlled trial of ganciclovir in recipients of bone marrow transplants who had asymptomatic pulmonary CMV infection. We also sought to identify risk factors for the development of CMV interstitial pneumonia. Methods. After bone marrow transplantation, 104 patients who had no evidence of respiratory disease underwent routine bronchoalveolar lavage on day 35. The 40 patients who had positive cultures for CMV were randomly assigned to either prophylactic ganciclovir or observation alone. Ganciclovir (5 mg per kilogram of body weight intravenously) was given twice daily for two weeks and then five times per week until day 120. Results. Of the 20 culture-positive patients who received prophylactic ganciclovir, 5 (25 percent) died or had CMV pneumonia before day 120, as compared with 14 of the 20 culture-positive control patients (70 percent) who w...

Sickle Cell Chronic Lung Disease: Prior Morbidity and the Risk of Pulmonary Failure

Sickle cell chronic lung disease (SCLD) is a prime contributor to mortality in young adult patients with sickle cell disease, especially those with sickle cell anemia (SS). Both perfusion and diffusion defects have been demonstrated, with generalized pulmonary fibrosis and disabling restrictive lung failure. We report 28 cases (25 SS, 1 S beta(0) thalassemia, 1 S beta(+) thalassemia and 1 SO-Arab) which began during the second decade of life and which ended in death by the fourth decade, after an ordered progression to pulmonary failure and cor pulmonale. Myocardial hypoxia with multifocal fibrosis and segmental infarction occurred in more than one-third of the cases and sudden death was a frequent final event. We define 4 stages of SCLD, based on pulmonary function tests, chest roentgenograms, blood gases, and noninvasive cardiac studies; each stage is 2 or 3 years in length, until death ensues in Stage 4. Case-control analysis showed that the significant risk factors associated with SCLD are 1) the total number of acute chest syndrome events in an individual before the onset of SCLD, (p = 0.0001), 2) sickle cell crisis marked by chest pain (p = 0.03) and 3) aseptic necrosis (p = 0.005). Temporal clustering of acute chest syndrome episodes frequently heralds the onset of SCLD. The pulmonary arterial bed, which has low oxygen tension and low pressure in a slow-flow system, is ideally suited to facilitate the polymerization of sickle hemoglobin, causing endothelial damage and culminating in an obstructive arteriolar vasculopathy. Identification of the significant risk factors predictive of SCLD can lead to early diagnosis of the disease; this is the only hope for effective intervention therapy.

An enhanced International Prognostic Index (NCCN-IPI) for patients with diffuse large B-cell lymphoma treated in the rituximab era.

The International Prognostic Index (IPI) has been the basis for determining prognosis in patients with aggressive non-Hodgkin lymphoma (NHL) for the past 20 years. Using raw clinical data from the National Comprehensive Cancer Network (NCCN) database collected during the rituximab era, we built an enhanced IPI with the goal of improving risk stratification. Clinical features from 1650 adults with de novo diffuse large B-cell lymphoma (DLBCL) diagnosed from 2000-2010 at 7 NCCN cancer centers were assessed for their prognostic significance, with statistical efforts to further refine the categorization of age and normalized LDH. Five predictors (age, lactate dehydrogenase (LDH), sites of involvement, Ann Arbor stage, ECOG performance status) were identified and a maximum of 8 points assigned. Four risk groups were formed: low (0-1), low-intermediate (2-3), high-intermediate (4-5), and high (6-8). Compared with the IPI, the NCCN-IPI better discriminated low- and high-risk subgroups (5-year overall survival [OS]: 96% vs 33%) than the IPI (5 year OS: 90% vs 54%), respectively. When validated using an independent cohort from the British Columbia Cancer Agency (n = 1138), it also demonstrated enhanced discrimination for both low- and high-risk patients. The NCCN-IPI is easy to apply and more powerful than the IPI for predicting survival in the rituximab era.

Cyclosporine, Methotrexate, and Prednisone Compared with Cyclosporine and Prednisone for Prophylaxis of Acute Graft-versus-Host Disease

BACKGROUND Acute graft-versus-host disease (GVHD) following allogeneic bone marrow transplantation remains a serious problem. In a clinical trial, we tested the combination of cyclosporine and prednisone with and without methotrexate for the prevention of GVHD. METHODS One hundred fifty patients with either acute leukemia in first complete remission, chronic myelogenous leukemia in first chronic phase, or lymphoblastic lymphoma in first complete remission were enrolled in the study. All the patients were given fractionated total-body irradiation (1320 cGy) and etoposide (60 mg per kilogram of body weight) in preparation for transplantation, and received bone marrow from genotypically histocompatible donors. To prevent GVHD, they were randomly assigned to prophylactic treatment with either cyclosporine, methotrexate, and prednisone or cyclosporine and prednisone without methotrexate. All the patients received standardized supportive care after transplantation, including intravenous gamma globulin. RESULTS Patients receiving cyclosporine, methotrexate, and prednisone had a significantly lower incidence of acute GVHD of grades II to IV (9 percent) than those receiving cyclosporine and prednisone (23 percent, P = 0.02). Multivariate regression analysis demonstrated that an increased risk of acute GVHD was associated with an elevated serum creatinine concentration (P = 0.006) and treatment with cyclosporine and prednisone alone (P = 0.02). The lower incidence of acute GVHD was not associated with a higher rate of relapse of leukemia or lymphoma. There was no significant difference in disease-free survival at three years between the two treatment groups (64 percent with the three-drug regimen vs. 59 percent with the two-drug regimen, P = 0.57). CONCLUSIONS The combination of cyclosporine, methotrexate, and prednisone was more effective in preventing acute GVHD of grades II to IV than was the combination of cyclosporine and prednisone without methotrexate.

Solid Cancers After Bone Marrow Transplantation

PURPOSE To evaluate the incidence and associated risk factors of solid cancers after bone marrow transplantation (BMT). PATIENTS AND METHODS We analyzed 2,129 patients who had undergone BMT for hematologic malignancies at the City of Hope National Medical Center between 1976 and 1998. A retrospective cohort and nested case-control study design were used to evaluate the role of pretransplantation therapeutic exposures and transplant conditioning regimens. RESULTS Twenty-nine patients developed solid cancers after BMT, which represents a two-fold increase in risk compared with a comparable normal population. The estimated cumulative probability (+/- SE) for development of a solid cancer was 6.1% +/- 1.6% at 10 years. The risk was significantly elevated for liver cancer (standardized incidence ratio [SIR], 27.7; 95% confidence interval [CI], 1.9 to 57.3), cancer of the oral cavity (SIR, 17.4; 95% CI, 6.3 to 34.1), and cervical cancer (SIR, 13.3; 95% CI, 3.5 to 29.6). Each of the two patients with liver cancer had a history of chronic hepatitis C infection. All six patients with squamous cell carcinoma of the skin had chronic graft-versus-host disease. The risk was significantly higher for survivors who were younger than 34 years of age at time of BMT (SIR, 5.3; 95% CI, 2.7 to 8.6). Cancers of the thyroid gland, liver, and oral cavity occurred primarily among patients who received total-body irradiation. CONCLUSION The risk of radiation-associated solid tumor development after BMT is likely to increase with longer follow-up. This underscores the importance of close monitoring of patients who undergo BMT.

Infection with Human Immunodeficiency Virus Type 1 (HIV-1) among Recipients of Antibody-Positive Blood Donations

OBJECTIVE To assess the incidence of human immunodeficiency virus type 1(HIV-1) transmission by antibody (anti-HIV-1)-positive blood components, and to determine the immunologic and clinical course in HIV-1-infected recipients. DESIGN AND SUBJECTS We retrospectively tested approximately 200,000 donor blood component specimens stored in late 1984 and 1985 for anti-HIV-1, and we contacted recipients of positive specimens to determine their serologic status. They were compared with both recipients of HIV-1-negative transfusions and healthy (untransfused) controls. Subjects were seen at 3- to 6-month intervals for up to 4 years for clinical and immunologic evaluations. MEASUREMENTS AND MAIN RESULTS Of 133 recipients, 9 had other possible exposures. Excluding these cases, 111 of 124 (89.5%) were anti-HIV-1-positive (95% CI, 84.1% to 94.5%). The recipients sex, age, underlying condition, and type of component did not influence infection rates. The cumulative risk for developing the acquired immunodeficiency syndrome (AIDS) within 38 months after transfusion was 13% (CI, 7.5% to 21.6%). At 36 +/- 3 months after the index transfusion, seropositive recipients had lower counts of CD2+CDw26+, CD4+, CD4+CD29+, and CD4+CD45RA+subsets and more CD8+I2+ lymphocytes than did recipients of anti-HIV-1-negative transfusions. The CD4+ and CD2+CDw26+subsets changed the most rapidly. The absolute CD8+ count remained normal. CONCLUSIONS Transfusion of anti-HIV-1-positive blood infected 90% of recipients. The rate of progression to AIDS within the first 38 months after infection was similar to that reported for homosexual men and hemophiliacs. Although most lymphocyte subset counts changed over time, CD8+ counts were constant.

A Multi-Institutional Analysis of the Socioeconomic Determinants of Breast Reconstruction: A Study of the National Comprehensive Cancer Network

Objective:To determine the rate of postmastectomy reconstruction and investigate the impact of socioeconomic status on the receipt of reconstruction. Summary Background Data:The National Comprehensive Cancer Network (NCCN) Outcomes Project is a prospective, multi-institutional database that contains data on all newly diagnosed breast cancer patients treated at one of the participating comprehensive cancer centers. Methods:The study cohort consisted of 2174 patients with DCIS and stage I, II, and III invasive breast cancer who underwent mastectomy at one of 8 NCCN centers. Rates of reconstruction were determined. Logistic regression analyses were used to evaluate whether socioeconomic characteristics are associated with breast reconstruction. Results:Overall, 42% of patients had breast reconstruction following mastectomy. Patients with Medicaid and Medicare were less likely to undergo reconstruction than those with managed care insurance; however, there was no difference for indemnity versus managed care insurance. Homemakers and retired patients had fewer reconstructions than those employed outside the home. Patients with a high school education or less were less likely to have reconstruction than those with more education. Race and ethnicity were not significant predictors of reconstruction. Conclusions:The reconstruction rate in this study (42%) is markedly higher than those previously reported. The type of insurance, education level, and employment status of a patient, but not her race or ethnicity, appear to influence the use of breast reconstruction. Because all patients were treated at an NCCN institution, these socioeconomic differences cannot be explained by access to care.

Prediction of systemic fungal infection in allogeneic marrow recipients: impact of amphotericin prophylaxis in high-risk patients.

PURPOSE To identify risk factors that might predict for systemic fungal infections in marrow transplant recipients within the first 100 days and to assess the efficacy of low-dose amphotericin B used as prophylaxis for candidemia and infection with invasive Aspergillus species in patients at risk. PATIENTS AND METHODS A retrospective analysis of transplant outcomes for 331 allogeneic marrow recipients transplanted between 1983 and 1989 was performed to identify patients who might be at increased risk of fungal infection. Factors analyzed included disease, remission status, transplant regimen, graft-versus-host disease (GVHD) prophylaxis, duration of neutropenia, and development of GVHD. A trial of low-dose amphotericin (5 to 10 mg/d) begun on day +1 and continuing for 2 to 3 months posttransplant was begun in 1987 to evaluate its utility in reducing systemic mycoses. RESULTS There were 18 episodes of candidemia and 18 systemic mycoses documented by blood or tissue culture or by biopsy. The initiation of high-dose (0.5 to 1 mg/kg/d) corticosteroids early as a component of GVHD prophylaxis in 1986 was identified as the most important risk factor for fungal infections, with a sixfold increase in infections as compared with the previous GVHD regimen (P < .0001); this was despite a significant decrease in the incidence of grade II to IV GVHD (7% v 43%; P = .0001). Low-dose amphotericin B initiated before the start of high-dose corticosteroid GVHD prophylaxis reduced the incidence of fungal infections from 30% to 9% (P = .01) without renal toxicity. Cyclosporine levels were lower in the patients who received amphotericin, leading to an increase in the rate of GVHD to 19% (P = .02). Controlling for GVHD prophylaxis, prolonged neutropenia (P = .00), and grade II to IV GVHD (P = .01) were also identified as risk factors for fungal infection. CONCLUSION Amphotericin B can be used in low doses as prophylaxis for fungal infections early in the posttransplant course. However, cyclosporine doses need to be monitored to maintain target levels.

Effect of Adjuvant Chemotherapy on Survival of Patients With Stage III Colon Cancer Diagnosed After Age 75 Years

PURPOSE Few patients 75 years of age and older participate in clinical trials, thus whether adjuvant chemotherapy for stage III colon cancer (CC) benefits this group is unknown. METHODS A total of 5,489 patients ≥ 75 years of age with resected stage III CC, diagnosed between 2004 and 2007, were selected from four data sets containing demographic, stage, treatment, and survival information. These data sets included SEER-Medicare, a linkage between the New York State Cancer Registry (NYSCR) and its Medicare programs, and prospective cohort studies Cancer Care Outcomes Research and Surveillance Consortium (CanCORS) and the National Comprehensive Cancer Network. Data sets were analyzed in parallel using covariate adjusted and propensity score (PS) matched proportional hazards models to evaluate the effect of treatment on survival. PS trimming was used to mitigate the effects of selection bias. RESULTS Use of adjuvant therapy declined with age and comorbidity. Chemotherapy receipt was associated with a survival benefit of comparable magnitude to clinical trials results (SEER-Medicare PS-matched mortality, hazard ratio [HR], 0.60; 95% CI, 0.53 to 0.68). The incremental benefit of oxaliplatin over non-oxaliplatin-containing regimens was also of similar magnitude to clinical trial results (SEER-Medicare, HR, 0.84; 95% CI, 0.69 to 1.04; NYSCR-Medicare, HR, 0.82, 95% CI, 0.51 to 1.33) in two of three examined data sources. However, statistical significance was inconsistent. The beneficial effect of chemotherapy and oxaliplatin did not seem solely attributable to confounding. CONCLUSION The noninvestigational experience suggests patients with stage III CC ≥ 75 years of age may anticipate a survival benefit from adjuvant chemotherapy. Oxaliplatin offers no more than a small incremental benefit. Use of adjuvant chemotherapy after the age of 75 years merits consideration in discussions that weigh individual risks and preferences.
