levoleucovorin and Infections

The aim of this study was to evaluate systematically the efficacy and safety of oral uracil-tegafur (UFT) plus leucovorin (LV) compared with infusional fluorouracil (5-FU) plus LV for advanced colorectal cancer.. Eligible studies were identified from Medline, Embase and the Cochrane Library. The end-points included overall survival and overall tumour response rate, and toxicity including leucopenia, febrile neutropenia, stomatitis/mucositis and diarrhoea.. Five randomized controlled trials were identified. Pooled data demonstrated no difference in overall survival between the oral UFT plus LV regimen and the 5-FU bolus plus LV regimen [hazard ratio 1.013; 95% confidence interval (CI) 0.911-1.127].The fixed-effect pooled estimate for overall tumour response rate showed no significant difference between the two regimens (relative risk 0.893; 0.672-1.187). Grade 3-4 leucopenia [odds ratio (OR) 0.126; 955 CI 0.048-0.326], grade 1-4 leucopenia (OR 0.089; 95% CI 0.067-0.119) and grade1-4 febrile neutropenia (OR 0.020; 95% CI 0.004-0.102) were significantly less prominent in the oral UFT regimens. For nonhaematological toxicities, grade 3-4 stomatitis/mucositis (OR 0.075; 95% CI 0.039-0.146), grade 3-4 infection (OR 0.484; 95% CI 0.310-0.758), grade 1-4 infection (OR 0.672; 95% CI 0.547-0.826, P < 0.001), grade 1-4 diarrhoea (OR 0.743; 95% CI 0.626-0.881) were also less likely to happen in patients in the oral UFT plus LV regimen, while there was no significant difference between the two treatment regimens with respect to grade 1-4 stomatitis/mucositis (OR 0.278; 95% CI 0.053-1.456) and grade 3-4 (OR 1.174; 95% CI 0.983-1.403) diarrhoea.. Oral UFT or 5-FU bolus combined with LV results in similar overall survival and tumour response rates for advanced colorectal cancer. The former treatment regimen is greatly superior in terms of toxicity, especially haematological toxicity.

We report the results of treatment with MACOP-B in 11 young patients with low grade lymphoma (LGL). Complete remission was obtained in 4 (57%) and partial remission in 3 (42.8%) of 7 evaluable patients. However, this aggressive chemotherapy has not offered any advantage because of an unacceptably high treatment-related morbidity and mortality (17%). Serious infection during neutropenia was the most common complication.

We conducted a pilot study in 20 patients with high-risk or recurrent/refractory non-Hodgkin's lymphoma (NHL) using high-dose sequential chemotherapy (HDSC) and autologous hematopoietic cell transplantation (AHCT). After cytoreduction with standard salvage therapy, HDSC/AHCT was administered in 4 phases at 2- to 4-week intervals. Phase 1 consisted of cyclophosphamide 7 g/m2 followed by granulocyte colony-stimulating factor (G-CSF) at 10 microg/kg per day and leukapheresis upon recovery from white blood cell nadir. The hematopoietic cell product was enriched by Percoll gradient separation and purged with a B-cell or T-cell monoclonal antibody panel and complement. Phase 2 consisted of methotrexate 8 g/m2 with leucovorin rescue and vincristine 1.4 mg/m2. Phase 3 was etoposide 2 g/m2 with G-CSF 5 microg/kg per day. In phase 4, the preparative regimen of mitoxantrone 60 mg/m2 and melphalan 180 mg/m2 was administered followed by AHCT. The NHL histologies were diffuse large cell, follicular/diffuse mixed, small noncleaved cell, T-cell-rich B-cell, lymphoblastic, and peripheral T cell. The remission status was first partial remission (PR1; n = 1) or beyond first complete remission (post-CR1; n = 19). Of the 20 patients enrolled, 11 proceeded through all 4 phases. Nine were removed from the study after the first or second phase because of progressive disease (n = 5), poor hematopoietic cell mobilization (n = 1), excessive toxicity (n = 2), and chronic active hepatitis C (n = 1). Treatment-related toxicities in the remaining 11 transplant recipients were cardiomyopathy, hemorrhagic cystitis, persistent cytopenias, acute renal failure, abnormal liver function test results, and infectious complications. There were no treatment-related deaths. Eight of the 11 transplant recipients were alive, 6 without disease, at a median follow-up of 2.7 years. The estimated median 2-year event-free survival was 55%, and overall survival was 70%. We conclude that HDSC/AHCT in refractory/recurrent NHL is associated with considerable acute and chronic toxicities. Given the toxicity profile, efficacy data were not sufficiently promising to warrant further study.

The majority of clinically recognizable acute infections in the neonate are bacterial. Such infections may be acquired from the mother prior to or at birth or from environmental sources. Because of the limited ability of neonates--especially those born prematurely--to express symptoms, even minor deviations from normal behavior should suggest bacterial disease. Chronic congenital and perinatal infections, unlike acute bacterial disease, are generally asymptomatic in mother and neonate and may remain latent or subclinically active in host tissue for prolonged periods, possibly causing insidious injury to the central nervous and perceptual systems. When overt, these infections almost invariably cause mental or perceptual handicaps or both. In view of the significant mortality and morbidity associated with either acute or chronic infections, diagnosis and treatment should be aggressive.
