Summary:In all, 22 patients with confirmed Fanconi anemia (FA) underwent stem cell transplantation (SCT) from HLAmatched, related donors at KFSHRC. Median age at SCT was 7.6 years (range, 2.5-14.6 years). Conditioning regimen consisted of cyclophosphamide (CY) 15 mg/kg/ day intravenously (i.v.) for 4 consecutive days, in addition to equine antithymocyte globulins (ATG) given i.v. at 40 mg/kg/day for four doses pre-SCT. No radiation therapy was given. For graft-versus-host disease prophylaxis, we used cyclosporin at the standard doses; ATG was added at 20 mg/kg/dose i.v. on days 2, 4, 6, 8, 10, and 12 post-SCT (total of six doses). All patients engrafted and are alive and transfusion independent with a median follow-up time of 20.2 months (range, 3.3-59 months). One patient however developed a decrease in her WBC and platelet count. Her work-up revealed slightly hypocellular bone marrow, and a series of chimerism studies over 1 year confirmed that she has stable mixed chimerism; she remains transfusion independent. We conclude that low-dose CY without radiation therapy can be used satisfactorily in the conditioning of patients with FA undergoing related SCT.
In Egypt, retinoblastoma patients present more frequently with advanced disease. There is an ever-increasing need to develop a national team dedicated to studying disease significance and formulating a national awareness program.
The outcome for advanced neuroblastoma has improved with combined modality therapy: induction chemotherapy, surgery, and consolidation with high-dose chemotherapy/autologous HSCT, followed by local radiation, cisretinoic acid, and recently antibody therapy. In the United States, the most common conditioning regimen is CEM, while in Europe/Middle East, Bu/Mel has been widely used; it remains unclear which regimen has the best outcome. Assess renal, hepatic, and infectious toxicity through Day+100 in 2 different regimens. Retrospective comparison between CEM-DFCHCC Boston and Bu/Mel- CCHE-57357. Thirty-five patients, median age 4, in Boston (2007-2011) and 38 patients, median age 3, in Cairo (2009-2011). Renal toxicity; creatinine was significantly higher in CEM than Bu/Mel: 57% (median day+90) vs. 29% (median>day+100), p = 0.004. One CEM patient died from renal dialysis at day+19. Hepatic toxicity was significantly higher in CEM than Bu/Mel: 80% (median day+26) vs. 58% (median day+60), p = 0.04. In infectious complications with CEM 14%, bacteremia (n = 4) and fungemia (n = 1), 3 had culture-negative sepsis requiring vasopressors. With Bu/Mel 18%, bacteremia (n = 7), none required pressors, p = 0.4. Bu/Mel was associated with less acute hepatic and renal toxicity and thus may be preferable for preserving organ functions.
Childhood cancer is a priority in Egypt due to large numbers of children with cancer, suboptimal care and insufficient resources. It is difficult to evaluate progress in survival because of paucity of data in National Cancer Registry. In this study, we studied survival rates and trends in survival of the largest available cohort of children with cancer (n = 15 779, aged 0‐18 years) from Egypt between 2007 and 2017, treated at Children's Cancer Hospital Egypt‐(CCHE), representing 40% to 50% of all childhood cancers across Egypt. We estimated 5‐year overall survival (OS) for 14 808 eligible patients using Kaplan‐Meier method, and determined survival trends using Cox regression by single year of diagnosis and by diagnosis periods. We compared age‐standardized rates to international benchmarks in England and the United States, identified cancers with inferior survival and provided recommendations for improvement. Five‐year OS was 72.1% (95% CI 71.3‐72.9) for all cancers combined, and survival trends increased significantly by single year of diagnosis (P < .001) and by calendar periods from 69.6% to 74.2% (P < .0001) between 2007‐2012 and 2013‐2017. Survival trends improved significantly for leukemias, lymphomas, CNS tumors, neuroblastoma, hepatoblastoma and Ewing Sarcoma. Survival was significantly lower by 9% and 11.2% (P < .001) than England and the United States, respectively. Significantly inferior survival was observed for the majority of cancers. Although survival trends are improving for childhood cancers in Egypt/CCHE, survival is still inferior in high‐income countries. We provide evidence‐based recommendations to improve survival in Egypt by reflecting on current obstacles in care, with further implications on practice and policy.
Background. Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma in children. Fifty percent of RMS cases occur in the first 10 years of life and less commonly in infants younger than one-year old. These infants require adapted multimodality treatment approaches. Patients and Methods. We analyzed patients' characteristics, treatment modalities, and the outcome for RMS infants treated at Children's Cancer Hospital Egypt (CCHE) between July 2007 and December 2010 and compared them to patients above one year treated on the same protocol. Results. Out of the 126 RMS treated during this period, 18 were below the age of one year. The male: female ratio was 1.25 : 1. The median age at diagnosis was 0.7 ± 0.2 years. Most of the cases (27.8%) were presented in head and neck regions. The estimated 4-years failure-free survival and overall survival for infants were 49 ± 12% and 70 ± 12%, respectively. These failure-free survival rate and overall survival rate did not differ from those for older patients (P = 0.2). Conclusion. Infants with RMS are a unique group of RMS who needs special concerns in tailoring treatment in addition to concerns regarding toxicity and morbidity in infants.
The routine use of echocardiography to screen for anthracycline-induced cardiac toxicity before and during chemotherapy identified myocardial dysfunction. Early medical intervention can improve cardiac parameters. Improved screening techniques with better sensitivity and predictability are needed.
Summary:Five patients with confirmed Fanconi's anemia (FA) and myelodysplasia and/or leukemia underwent stem cell transplantation (SCT) from related donors at KFSHRC. The median age at SCT was 12.6 year (range, 6.2-15 years). Conditioning regimen consisted of cyclophosphamide (CY) 5 mg/kg/day i.v. for 4 days, total body irradiation (TBI) 450 cGy in a single dose. Graft-versus-host disease (GVHD) prophylaxis was with cyclosporine and antithymocyte globulins (ATG). The median time to engraftment (defined as ANCX0.5 Â 10 9 /l) was 16 days (range, 12-26 days). The median time to a self-sustaining platelet count of X20 Â 10 9 /l was 27 days (range, 12-40 days). All patients engrafted. Two patients developed acute GVHD; one of the gut (grade 3) and the other of the skin (grade 1), and one patient developed chronic GVHD of the liver. Four are alive and well with no evidence of the disease; one patient died of bacterial sepsis after controlling her GVHD and clearing her pulmonary aspergillosis and CMV infection. We conclude that the use of low-dose CY plus TBI in patients with FA and MDS/AML undergoing SCT is adequate; the regimen is well tolerated and may be curative for such patients.
