Full-dose ifosfamide can be safely administered to outpatients.

This report compares a traditional full-dose ifosfamide administration modality (24-hr hyperhydration and mesna infusion) with a simplified 9-hr hyperhydration and mesna infusion for use in outpatients. Acute ifosfamide toxicity was the same, suggesting that ifosfamide could be safely administered to outpatients, reducing the currently-recommended prolonged hyperhydration and mesna uroprotection, thus resulting in shorter hospital stays and consequently lower costs.

Prognostic factors in pleuro-pulmonary blastoma.

PURPOSE: To evaluate the prognostic factors in a series of children affected by pleuropulmonary blastoma (PPB). PATIENTS AND METHODS: Clinicopathological findings, treatment, and outcome of 22 PPB cases observed in 13 Italian Associations for Pediatric Hematology and Oncology centers are reported. Clinical data, surgical notes, pathologic findings, and summaries of treatment were taken from the charts and correlated with outcome by standard statistical methods. RESULTS: The series included 22 patients (14 males) with a median age of 30.5 months followed up for a median of 22 months (range 2-176 months). In nine patients the PPB developed with lung involvement only. Congenital lung cysts were recorded in five cases. Nine patients had recurrences. Gender, side, tumor size, pre-existing lung cysts, and extent of surgical resection at diagnosis did not significantly affect survival by univariate analysis. Achieving total resection of the tumor at any time of treatment resulted in a significantly better prognosis (P = 0.01), whereas extrapulmonary involvement at diagnosis resulted in a significantly worse prognosis (P = 0.01). Estimated 15-year event-free and overall survival rates were 44 and 49% for all patients, respectively. CONCLUSIONS: PPB is an aggressive neoplasm. Total resection of PPB performed at any time of treatment appears to provide a better outcome, whereas extrapulmonary involvement at diagnosis worsens the prognosis.

The challenge of very rare tumours in childhood: the Italian TREP project.

A national cooperative project on rare paediatric tumours (the TREP project) was launched in 2000 in Italy, with a view to improving the clinical management and the basic research on these 'orphan' tumours, defined as those childhood solid malignancies characterised by an annual incidence <2/million and not considered in other clinical trials. This paper describes the process that the group developed and the problems it had to face, and aims to stimulate a debate on the rationale, scientific relevance and feasibility of running scientific research programs on rare childhood neoplasms. In the first phase of its activity, the project developed diagnostic and therapeutic recommendations for each rare tumour and established a collaborative network between 'experts' dedicated to each histotype and other specialists (i.e. adult oncologists, surgeons) involved in the management of these tumours. From 2000 to 2005, 297 patients have been registered from 35 Italian centres. This experience demonstrates the feasibility of a national multidisciplinary cooperation on rare paediatric malignancies and suggests that international studies could be realised.

Evaluation of health status and health-related quality of life in a cohort of Italian children following treatment for a primary brain tumor.

BACKGROUND: This study is a pilot experience aiming to investigate the compliance of an institutional cohort of Italian children treated for a malignant disease and their families in completing the health utilities index2, (HUI2) and the effectiveness of this measured in terms of their health status (HS) and health-related quality of life (HRQL). It specifically, it aimed to compare the HS and the HRQL, as expressed by the HUI2 global utility score, in cohorts of patients who had brain tumors, extra-cerebral solid tumors, or leukemia/lymphoma. PROCEDURE: Fifty survivors of brain tumors, between 8 and 30 years at the time of the assessment ("self") and/or their parents ("proxy"), attending the Pediatric Oncology Out Patient clinic of Padua, Italy, completed the HUI2 questionnaire. Eighty-nine children with acute leukemia/lymphoma and 74 with extra-cerebral solid tumors and/or their parents were also assessed. RESULTS: The mean "self" and "proxy" HUI2 global utility scores in the brain tumor patients were 0.87 and 0.84, respectively, while in the cohorts of children with other solid tumors and leukemia/lymphoma, there were 0.94, 0.91, 0.96, and 0.92, respectively. The differences between the HUI2 global utility scores in the "self" and "proxy" assessment within each cohort of children were not statistically significant. In decreasing order of frequency, the attributes affected most commonly were: "emotion," "pain," "sensation," and "cognition" both by "self" and "proxy" assessment. CONCLUSIONS: In this Italian population of childhood cancer survivors the HUI2 questionnaire proved to be a user-friendly tool, which provided information regarding HS and HRQL. A larger cohort of cancer children is needed to confirm the efficacy of the HUI2 questionnaire in distinguishing groups of children on this basis by disease category.

Phase II study of a protracted irinotecan schedule in children with refractory or recurrent soft tissue sarcoma.

BACKGROUND: Irinotecan (CPT-11) is a novel antineoplastic agent that takes effect by inhibiting topoisomerase I. The Italian Soft Tissue Sarcoma (STS) Committee performed a multiinstitutional Phase II study to evaluate its effect on STS. METHODS: Over a 2-year period between 2002 and 2004, 32 heavily pretreated patients were administered 60-minute infusions of irinotecan at 20 mg/m2/day, for 5 days a week, for 2 consecutive weeks. The courses were repeated every 4 weeks for at least 2 courses, unless there were signs of toxicity or disease progression. Thirty patients, 13 with peripheral primitive neuroectodermal tumor (PNET), 12 with rhabdomyosarcoma (RMS), 3 with desmoplastic small round cell tumor (DSRCT), and 2 with other STS were evaluable for response. RESULTS: A total of 79 cycles were delivered. The main regimen-related toxicity was diarrhea, occurring in 58% of cycles with 9 episodes graded as 3 or 4. Grade 3-4 neutropenia was recorded in 10% of cycles. The overall response rate was 23% (2 complete remissions +5 partial remissions of 30 patients), 38% for PNET and 16% for RMS. In addition, 4 minor responses were noted. CONCLUSIONS: As a single agent in the treatment of recurrent and refractory STS, irinotecan administered on a daily x5 x2 schedule revealed a noteworthy response rate in a population of heavily pretreated patients, especially in the subset of patients with PNET. Its hematologic toxicity profile warrants further investigation in association with other myelotoxic agents.

Epithelioid sarcoma in children and adolescents: a report from the Italian Soft Tissue Sarcoma Committee.

BACKGROUND: Epithelioid sarcoma (ES) is an uncommon malignant soft tissue tumor. To the authors' knowledge, little information is available to date concerning its clinical features and management in children and adolescents, particularly with regard to the recently described proximal-type variant. The current study concerns 30 patients age<18 years who were enrolled in the Italian Soft Tissue Sarcoma Committee protocols. METHODS: Histopathologic specimens, clinical data, and treatment modalities were reviewed for the current analysis. Nineteen patients had classic ES and 11 had proximal-type ES. Surgery was the mainstay of treatment; radiotherapy was given to six patients considered to be at risk of local disease recurrence due to incomplete resection, and chemotherapy was administered to eight patients. RESULTS: With a median follow-up of 66 months, the 5-year event-free survival (EFS) and overall survival (OS) rates were 61.7% and 92.4%, respectively, but the OS rate dropped to 86.9% and 72.4%, respectively, at 10 years and 15 years. Local disease recurrence was the major cause of treatment failure. The most significant finding influencing both EFS and OS was tumor site, with a tumor location in the extremities predicting a favorable outcome. Initially unfavorable clinical findings and a worse outcome were associated with the proximal-type variant of ES. A response to chemotherapy was noted in three of the seven patients with measurable disease. CONCLUSIONS: The current study confirms some typical features of ES (i.e., the peculiar superficial distal location [i.e., the hand, fingers], indolent growth, and a tendency to recur locally). The current study data do not clearly confirm the strong tendency for the lymph node involvement described in adult ES patients. Further studies are needed to better define the clinical behavior and biology of the proximal-type variant of ES.

Grossly-resected synovial sarcoma treated by the German and Italian Pediatric Soft Tissue Sarcoma Cooperative Groups: discussion on the role of adjuvant therapies.

Differently from adult oncologists that considered synovial sarcoma (SS) a tumor with uncertain chemosensitiveness, since two decades pediatric oncologists in Europe assumed that chemotherapy played an important role in SS treatment, so most pediatric patients were included in rhabdomyosarcoma protocols, receiving adjuvant chemotherapy regardless of risk factors. The German and Italian groups reviewed the data of grossly resected SS patients in order to define a risk-adapted treatment program for the next European protocol. A total of 150 patients < 21 years with localized SS who underwent initial gross resection between 1975 and 2002 were the object of this study. All but four cases received adjuvant chemotherapy. Post-operative radiotherapy was administered to 50% Group I and to 92% Group II patients. Five-year event-free survival (EFS) and overall survival (OS) were 77% and 89%, respectively. Survival rates were influenced by tumor size (EFS 92% and 56% for size < or = and > 5 cm, respectively) and local invasiveness, not by surgical margins. No metastatic relapses occurred in Group I < or = 5 cm patients, while the outcome was poor for T2B patients (EFS 41%) due to a high rate of metastatic relapse. Our study was unable to assess the role of adjuvant treatments in grossly-resected SS, but identified a subset of low-risk patients (IRS Group I, size < or = 5 cm), for which the omission of adjuvant chemotherapy could be suggested, and a subset of high-risk patients (T2B), who need treatment intensification.

Late effects in 164 patients with rhabdomyosarcoma of the bladder/prostate region: a report from the international workshop.

PURPOSE: We determined the late sequelae in children and adolescents with rhabdomyosarcoma of the bladder/prostate treated in the United States, Canada and selected Western European countries, primarily France, Germany, Italy and the United Kingdom, from 1979 to 1998. MATERIALS AND METHODS: We used a data collection form to record data from patient records available at the group statistical centers. RESULTS: A total of 164 patient charts had sufficient data available to be included in the study. Median patient age at diagnosis was 2.4 years. Median length of followup was approximately 8 years (range 3 to 24). Of the patients with available data 78 did not undergo cystectomy, 49 underwent partial cystectomy and 34 underwent complete cystectomy. Urinary continence was assessed at age 6 years or older in 62 patients who did not undergo cystectomy. Of these patients 43 (69%) were continent, 16 had nocturnal incontinence and 9 had diurnal incontinence. Of 44 patients who underwent partial cystectomy and had pertinent followup data 32 (73%) were continent, and 12 had nocturnal and/or diurnal incontinence. Only 11 patients underwent urodynamic investigation. Other nephrourological complications consisted of 3 or more urinary tract infections in 29 of 53 patients, abnormal renal function in 19 of 48 (tubulopathy 14, increased creatinine/blood urea nitrogen 5), chronic hematuria in 13 of 51 and hydronephrosis in 8 of 54 with available data. Vesicoureteral reflux, urinary stones and bowel problems were infrequent. CONCLUSIONS: Of the patients 48% had a relatively intact bladder after biopsy only. However, 31% of patients 6 years or older had some urinary incontinence, as did 27% of patients who had undergone partial cystectomy. In addition, 55% of all patients had 3 or more urinary tract infections, 40% had decreased renal function and 25% had chronic hematuria. Other complications were present in 15% or less of the patients with available data.

Orthotopic continent urinary diversion after radical cystectomy in pediatric patients with genitourinary rhabdomyosarcoma.

PURPOSE: We present our experience with orthotopic continent urinary diversion following radical cystectomy due to genitourinary rhabdomyosarcoma in children not responding to radiotherapy or chemotherapy. MATERIALS AND METHODS: Four children with persistent genitourinary rhabdomyosarcoma underwent radical cystectomy with reconstruction of an orthotopic ileal neobladder. RESULTS: Average followup was 50.7 months. One patient died at 12 months postoperatively due to pulmonary recurrence. All patients were able to void completely at regular intervals. Renal function was normal in all patients. Average reservoir capacity was 250 ml. Daytime and nighttime urinary continence was achieved in all patients. CONCLUSIONS: The orthotopic continent urinary diversion is technically feasible even in small children. It represents a safe long-term option and offers good quality of life after disfiguring surgery. In fact, patients are able to void spontaneously through the urethra.

Rituximab (anti-CD20 monoclonal antibody) in children with chronic refractory symptomatic immune thrombocytopenic purpura: efficacy and safety of treatment.

This retrospective study investigated the effects of rituximab in 19 pediatric patients (15 girls and 4 boys) with chronic refractory symptomatic immune thrombocytopenic purpura (ITP). Patients received from 2 to 5 weekly infusions of rituximab (375 mg/m(2)); 15 patients were younger than 12 years when treated. The median follow-up time was 30 months (range, 9-43 months). The overall response rate was 68% (13/19 patients). Six responders relapsed at a median of 4.5 months (range, 3-8 months). Seven patients still displayed a platelet count >150,000/microL at a median of 33 months (range, 14-43 months) after rituximab treatment. Six of 15 patients treated with 4 or 5 weekly infusions and 1 of 4 patients treated with 2 or 3 infusions are still in remission. No difference was detected between splenectomized and nonsplenectomized patients. The duration of ITP disease at the time of treatment did not influence the response rate. Patients still in remission showed significantly lower levels of CD19+ cells after 4 and 6 months than nonresponding or relapsed patients (P < .05). No major infections were reported during follow-up. Our data show the efficacy and tolerability of rituximab in young children with refractory symptomatic ITP. Nonrelapsed patients showed a more prolonged B-cell depletion.

Pediatric malignant peripheral nerve sheath tumor: the Italian and German soft tissue sarcoma cooperative group.

PURPOSE: To assess the value of chemotherapy and radiotherapy in children with malignant peripheral nerve sheath tumors (MPNSTs) and to identify risk factors associated with outcome. PATIENTS AND METHODS: A total of 167 untreated eligible patients enrolled onto the Italian and German studies between 1975 and 1998 entered this analysis. Seventeen percent of patients had neurofibromatosis type 1 (NF1). Chemotherapy was administered to 74% of patients; radiotherapy was administered to 38% of patients. RESULTS: With a median follow-up of 7 years, 5-year overall survival (OS) and progression-free survival (PFS) were 51% and 37%, respectively. The 5-year OS and PFS by Intergroup Rhabdomyosarcoma Study (IRS) groupings were as follows: group I, 82% and 61%; group II, 62% and 37%; group III, 32% and 27%; group IV, 26% and 21%, respectively. Univariate analysis identified IRS groups, size, invasiveness, primary site, age, and presence of NF1 as prognostic factors; multivariate analysis identified absence of NF1, tumor invasiveness T1, IRS groups I to II and extremity of primary site as independent favorable factors for OS. A trend was observed toward a benefit from radiotherapy after initial gross resection. The overall response rate to primary chemotherapy, including minor responses, in group III patients was 45%. CONCLUSION: MPNST is an aggressive tumor for which complete surgical resection is the mainstay of successful treatment. Postoperative radiotherapy may have a role in improving local control in patients with minimal residual tumor. The reported responses to primary chemotherapy suggest that it may be effective in patients with tumor considered unresectable at diagnosis.

Localized unresectable non-rhabdo soft tissue sarcomas of the extremities in pediatric age: results from the Italian studies.

BACKGROUND: Treatment of initially unresectable nonrhabdo soft tissue sarcomas (NRSTS) in pediatric age is debated, due to their different chemosensitivity. The authors objective was to evaluate clinical features and treatment results observed in a series of Italian patients over a 24-year period. METHODS: Fifty-two patients age 8-18 years (median 8 years) were observed (1979-2002). Primary sites were on the lower limbs in 41 and on the upper limbs in 11 cases. Clinical TNM and surgical Intergroup Rhabdomyosarcoma Staging systems were adopted. Therapeutic guidelines recommended an initial biopsy plus neoadjuvant chemotherapy. Aggressive delayed surgery of residual disease, including compartmental resections, was recommended. Radiotherapy was suggested only for patients age > 3 years when surgery was incomplete or not feasible. RESULTS: The evaluation was performed dividing the patients into two categories according to their chemosensitivity. Chemosensitive (CTs) sarcomas, 21: synovial sarcoma, 11; extraosseous Ewing sarcomas, 5; primitive peripheral neuroectodermic tumors, 5. Nonchemosensitive (CTns) sarcomas, 31: fibrosarcoma, 11; malignant peripheral nerve sheet tumors, 10; liposarcoma, 2; hemangiopericitoma adult type, 2; epithelioid sarcoma, 2; and alveolar soft part sarcoma, leiomyosarcoma, clear cell sarcoma, and sarcoma NOS, each 1. Nineteen of 21 patients with CTs-NRSTS were alive without disease: the 5-year overall survival (OS) and progression-free survival (PFS) were 94.4% and 79.3%, respectively; 23 of 31 patients with CTns-NRSTS were alive without disease: 5-year OS and PFS were 75.3% and 68.3%, respectively. Response to neoadjuvant chemotherapy was complete or partial in 10 of 20 evaluable CTs and in 8 of 26 evaluable CTns tumors. The achievement of complete delayed resection was particularly important for CTns-NRSTS. Tumor size < 5 cm, distal site, and tumor grading for CTns sarcomas were often linked to a favorable outcome; no conclusive results were detected concerning age of the patients or T status of the tumor. CONCLUSIONS: Multidisciplinary treatment without mutilating procedures allowed the cure of most patients with CTs and CTns-NRSTS. Relapses were cured in several cases of CTs tumors, whereas almost all patients with relapsed CTns tumors died due to the high rate of metastatic spread.

Outcomes and prognostic factors after recurrence in children and adolescents with nonmetastatic rhabdomyosarcoma.

BACKGROUND: Although > 90% of children with nonmetastatic rhabdomyosarcoma (RMS) achieve complete remission with current treatment, up to one-third of them experience a recurrence. Survival rates are not always poor in patients who develop recurrences; thus, prognostic factors are needed to tailor salvage treatment. METHODS: The current analysis included 125 children who were affected by localized RMS and were enrolled in 3 consecutive Italian protocols (RMS79, RMS88, and RMS96) who developed recurrences after complete remission. Patient, tumor, and treatment characteristics were studied in univariate and multivariate analyses to determine the independent significance of different factors. RESULTS: The median time from diagnosis to recurrence was 17.8 months. Most patients had local recurrences (72%). The 5-year overall survival (OS) rate was 28.3% +/- 8.7%. Multivariate analysis identified 4 factors that were associated with poor survival: 1) alveolar subtype (relative risk [RR], 2.0), 2) parameningeal or "other" sites (RR, 2.6), 3) systemic recurrence (RR, 3.1), and 4) recurrence on therapy (RR, 2.3). The absence of any of these risk factors identified a "favorable risk" group (12% of patients) with a 5-year OS rate of 71.8% +/- 23.5%. Patients with a single risk factor (32%) had an OS rate of 37.5% +/- 17.2%. Combining patients with 0 or 1 risk factor, the OS rate was 66.5% in the subgroup who had not received radiotherapy compared with an OS rate of 30.3% in the subgroup who had received radiotherapy; this difference was significant (P = 0.03). CONCLUSIONS: The results of the current analysis demonstrated that groups with a different prognosis can be identified among patients with recurrent RMS. Patients with a nonalveolar histology, a primary site other than the parameningeal or "other" sites, local recurrence, and recurrence off therapy had a better prognosis. First-line treatment may have an impact on prognostic variables. In fact, patients who had no or only one risk factor and patients who had tumors with a nonalveolar histology benefited more from salvage therapy if they had not received radiotherapy for their initial treatment. These data may be useful in planning risk-adapted salvage protocols.

The IVADo regimen--a pilot study with ifosfamide, vincristine, actinomycin D, and doxorubicin in children with metastatic soft tissue sarcoma: a pilot study of behalf of the European pediatric Soft tissue sarcoma Study Group.

BACKGROUND: The role of doxorubicin (Doxo) as part of multidrug regimens used to treat children with soft tissue sarcoma (STS) is controversial. To evaluate the feasibility of combining Doxo with the well established ifosfamide, vincristine, and actinomycin D (IVA) regimen, the Italian STS Committee performed a pilot study on a series of children with metastatic STS. METHODS: Between July 2002 and February 2004, 29 evaluable patients were enrolled in this study; 19 patients had rhabdomyosarcoma, 5 patients had peripheral neuroectodermal tumor, and 5 patients had other types of STS. The IVA-Doxo (IVADo) regimen included ifosfamide 3 g/m(2) on Days 1 and 2, vincristine 1.5 mg/m(2) on Day 1, actinomycin D 1.5 mg/m(2) on Day 1, and Doxo 30 mg/m(2) on Days 1 and 2. Three courses of IVADo were to be administered in the initial part of treatment and analyzed for toxicity and tumor response. RESULTS: Overall, 92 cycles were delivered. Major regimen-related toxicity was myelosuppression, with Grade 4 neutropenia in 67% of cycles and fever and neutropenia in 37% of cycles. Nonhematologic toxicity included Grade 3-4 mucositis (6.5% of cycles), constipation (9.7%), and peripheral neuropathy (6.5%). Other manifestations of major toxicity were venoocclusive disease and seizures, which occurred in one patient each. All but 1 patient with a malignant schwannoma showed some degree of tumor volume reduction; however, considering only complete and partial remissions, the response rate was 76% (+/- 7.9%). CONCLUSIONS: The intensive IVADo regimen was effective against pediatric STS with acceptable toxicity. This combination will be investigated in high-risk patients with rhabdomyosarcoma in a randomized trial launched by the European pediatric Soft tissue sarcoma Study Group.

A case of vinblastine overdose managed with plasma exchange.

Severe, life-threatening toxicity may be caused by errors in chemotherapy administration. To contribute with some useful information on drug-induced toxic effects and salvage therapy, we report a case of vinblastine (VBL) overdose (25 mg/m(2)) in a 12-year-old child affected by an end-stage metastatic primitive neuroectodermal tumor. Early signs of toxicity were acute, severe musculoskeletal pain and fever. This was followed by intestinal hypotonia, severe esophagitis, and peripheral neuropathy. Two consecutive plasma exchange procedures were performed at 4 and 18 hr after the administration of the overdose of VBL. The overall toxicity this child experienced was much less severe than expected; this finding, in combination with the known pharmacokinectis data of VBL in children, made us hypothesize that plasma exchange might have had a role in lowering the side effects of drug over dosage.

The role of adjuvant chemotherapy in children and adolescents with surgically resected, high-risk adult-type soft tissue sarcomas.

PURPOSE: This analysis evaluates whether adjuvant chemotherapy can be recommended for high-risk, surgically-resected, adult-type non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) within the new European Pediatric Soft Tissue Sarcoma Study Group (EpSSG) protocol. The Italian and German Cooperative Groups reviewed their data-bases, analyzing patients classified as group I-II, with high-grade tumor (G3) larger than 5 cm in size. METHODS: The analysis included 36 patients, and compared the clinical features and outcome of the group of 21 patients who received chemotherapy versus the group of 15 patients treated with local therapies only. RESULTS: For the series as a whole, 5-year event-free survival (EFS), metastasis-free survival (MFS), and overall survival (OS) were 26.2%, 34.0%, and 37.5%, respectively. In patients treated with chemotherapy, MFS and OS were 49.5% and 41.5% (median time to relapse: 13 months). In patients who did not receive chemotherapy, MFS and OS were 0% and 23.8% (median time to relapse: 3 months). CONCLUSION: The role of adjuvant chemotherapy in NRSTS is still uncertain, however, the current retrospective analysis showed that: (1) despite the globally good prognosis of grossly-resected cases, patients with G3 and large-size have a high-risk of metastatic spread, and (2) MFS appears to be better in patients who had chemotherapy. Based in part on these results, and in accordance with recent suggestions coming from the literature on adult sarcomas, the EpSSG NRSTS protocol will recommend adjuvant chemotherapy in high-risk surgically-resected patients.
