Hypersensitivity to carboplatin in children.
. Abstract: Background. Hypersensitivity reactions are rare bur at times severe complications to cytostatic drugs. Procedure. The percentage of allergic reactions to carboplatin and their clinical features were evaluated in 185 children affected by different so lid tumors and treated with etoposide-carboplatin chemotherapy. Allergic reactions that occurred during or immediately following etoposide infusion (5 cases, 2.8%) were excluded from the study. Results. Seventeen out of 185 patients (9.2%) suffered from allergic responses to carboplatin. The first of these occurred after an average of 10.1 courses (range, 1-23; median, 9). The risk calculated according to the number of courses is 2% at 6 courses, 11.3% at 12 courses, and 47% at more than 12 courses. Conclusions. The high risk of allergic reactions to multiple courses of carboplatin should be kept in mind when developing treatment regimens that include the drug
Evaluation of Nephron-Sparing Surgery as Potential Risk Factor for Relapse in Unilateral Wilms Tumor
Background: The aim of the study was to assess the prognostic significance of nephron-sparing surgery (NSS) without tumor size limits as a risk factor for relapse in children with unilateral Wilms Tumor (WT). Methods: A 28-y retrospective single-center review was performed. Prognostic relevance of age, gender, stage, histology, nephrectomy (N), and NSS was analyzed. Results: Sixty-nine cases (42 females and 27 males) with WT, off-therapy from 21 to 325 mo after chemotherapy mainly based on the International Society of Pediatric Oncology trials, were treated at our institution. Five cases were excluded (three children with synchronous bilateral WT and two adults with unilateral WT). Of 64 children with unilateral WT, 51 underwent N and 13 NSS without tumor size limits. Indeed, two-thirds of children who underwent NSS presented with a tumor diameter >4 cm. Overall, nine patients (14%) had a relapse (male-to-female ratio = 1:8). Initial surgery was N in eight cases and NSS in another one. Relapse rates in N and NSS groups were 15.7% and 7.7% (P = nonsignificant), respectively; the relapse rates in N and NSS groups were 8.6% and 7.7% (P = nonsignificant) for stages I-II unilateral WT cohort, respectively. On univariate analysis, factors correlated with probability of relapse were unfavorable histology (P < 0.002) and stage III disease (P < 0.01). Conclusions: In unilateral WT, NSS, whenever feasible, does not seem to increase the risk of recurrence. A multicenter prospective trial is required to carefully evaluate this risk
Ultrasound in the management of hepatic veno-occlusive disease in three children treated with dactinomycin and vincristine.
Three children, treated with dactinomycin and vincristine without radiotherapy showed hepatic toxicity consistent with diagnostic criteria for hepatic veno-occlusive disease (VOD). Two patients were affected with Wilms' tumor and the third with malignant fibromatosis. The clinical manifestations of VOD were mild and regressed in all patients after supportive therapy. Serial ultrasonography (US) was performed in all cases and was useful in confirming the diagnosis and in evaluating the severity of the disease. US features of VOD were hepatomegaly, gallbladder wall thickening, ill-defined borders of the hepatic vessels, and ascites. Parenchymal heterogeneity was still present after several months as a result of the hepatic injury. The hazy appearance of the portal vessels and the gallbladder wall thickening seemed directly correlated with the degree of hepatic involvement in the early phase of VOD

Use of ICRF-187 for prevention of anthracycline cardiotoxicity in children: Preliminary results
The objective of this study is to assess the efficacy of ICRF-187 as a protective agent against anthracycline cardiotoxicity. Cardiac function was evaluated by echocardiography before and after each cycle of anthracycline chemotherapy associated with ICRF-187 and compared with that of a second group receiving anthracycline chemotherapy without ICRF-187. The patients were a group of 15 consecutive children affected with various types of solid tuners who were treated with either doxorubicin-daunomycin or epirubicin (average doses 340 and 280 mg/m(2), respectively), and treatment was associated with ICRF-187. A second group of 15 consecutive children affected With different malignancies werre simultaneously treated with either doxorubicin-daunomycin or epirubicin (average doses 309 and 270 mg/m(2), respectively), but without ICRF-187 association. None of the patients treated with anthracyclines and ICRF-187 association showed abnormalities on echocardiographic examination. In the second group of patients treated with anthracyclines but without ICRF-187 association, we observed a decrease in the left ventricular ejection fraction to <55% and a decrease in the left ventricular fractional shortening to <28% in two patients (13.3%). One of these (6.6%) showed a dilatative cardiomyopathy. Both groups of patients were treated with low doses of anthracyclines. Although this study was not randomized, in patients without ICRF-87 cardioprotection, there was a trend for a worse evolution with one case of clinical cardiomyopathy as well as subclinical cardiac abnormalities
Metastatic medulloblastoma in 10-year-old girl treated successfully with chemotherapy without radiotherapy
We report a case of high risk medulloblastoma with leptomeningeal intracranial and spinal metastasis in a 10-year-old girl treated successfully with conventional prolonged chemotherapy without radiotherapy. This is a particular case of medulloblastoma that at onset did not receive standard therapy for medulloblastoma i.e. neither surgery nor craniospinal irradiation. This 10-year-old Chinese girl affected with localized medulloblastoma was previously treated at a medical department in China only with radiotherapy on the posterior fossa. When the child arrived in Italy with progressed metastatic medulloblastoma, she was treated with carboplatin/etoposide association i.v. followed by oral etoposide and partial surgery of the primitive mass. The schedule of chemotherapy was etoposide 300 mg/sqm followed by carboplatin 1000 mg/sqm in one day every 21-28 days for the first six courses, then etoposide 200 mg/sqm and carboplatin 600 mg/sqm in one day every 28-35 days for further 11 courses and oral etoposide 50 mg/sqm/day for ten consecutive days and one week interval between two cycles for one year. At present the girl is alive and disease-free, and has been off-therapy for 31 months. Interestingly, in this case a long-lasting complete remission was obtained without radiotherapy and without myeloablative chemotherapy. Oral etoposide played an important role in achieving a complete remissio
