ABSTRACT
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.
ABSTRACT
BACKGROUND AND PURPOSE: Neuroblastoma is the most common extracranial and deadly solid tumor in children. It accounts for 15% of the deaths from cancer in the pediatric age group. Approximately half of the newly diagnosed children are at "high risk" of treatment failure. The aim of this study is to evaluate the response rate of salvage chemotherapy by the ICE (Ifosfamide, Carboplatin, and Etoposide) regimen when administered to previously treated primary refractory or progressive high risk neuroblastoma patients. PATIENTS AND METHODS: Sixty-six patients from the National Cancer Institute (NCI), Cairo University and the Children Cancer Hospital Egypt (CCHE) received salvage chemotherapy (ICE) either due to primary resistance in 51/66 (77.2%) or due to disease progression on primary chemotherapy in 15/66 (22.8%). RESULTS: They were 40 males (60.6%) and 26 females (39.4%). Patients' age ranged between 3 months and 12.5 years. The most common tumor site was suprarenal, followed by retroperitoneal mass. Two patients (3%) died from chemotherapy toxicity during ICE administration. Evaluation of tumor response in the remaining 64 patients showed the following: CR/PR in 24 patients (36.5%), SD in 11 patients (16.6%), and PD in 29 patients (43.9%). Fourteen patients (21.2%) were considered eligible for auto BMT, while 50/64 patients (78.8%) failed this second line (salvage) chemotherapy and had palliative lines of therapy. By the end of the study (May 2010), 47/66 (71.2%) of the patients were still alive, while 19/66 (28.8%) were dead. Two out of 14 patients (14.2%) who underwent HSCT died from post transplantation disease progression, while 12/14 (85.8%) were in CCR. CONCLUSION: Chemotherapy by ICE for primary resistant or progressive stage III/IV NB seems well tolerated. With a 36.6% response rate, 18% CCR, and 3% treatment mortality rate, it could be considered a good salvage therapy in the category of patients who are condemned for palliation.
