Continuing response to subsequent treatment lines with tyrosine kinase inhibitors in an adolescent with metastatic renal cell carcinoma.

A 14-year-old girl with metastatic renal cell carcinoma was treated with nephrectomy, interferon, and several lines of the targeted agents sorafenib, bevacizumab, sunitinib, and everolimus, either alone or in combination. Treatment was well tolerated, but the patient developed hypothyroidism and significant hypertension with bevacizumab and sunitinib. She responded to all agents and was given radiation treatment twice at the time of symptomatic disease progression; she died 33 months from diagnosis.

Short topotecan-based induction regimen in newly diagnosed high-risk neuroblastoma.

Purpose: Topotecan is an active drug in relapsed neuroblastoma. We investigated the efficacy and toxicity of a topotecan-based induction regimen in newly diagnosed neuroblastoma.

Methods: Patients older than 1 year with either metastatic or localised stage 2-3 MYCN-amplified neuroblastoma received 2 courses of high-dose topotecan (HD-TPT) 6mg/m(2) and high-dose cyclophosphamide (HD-CPM) 140 mg/kg, followed by 2 courses of ifosfamide, carboplatin and etoposide (ICE) every 28 days.

Successful treatment of trilateral retinoblastoma with conventional and high-dose chemotherapy plus radiotherapy: a case report.

Trilateral retinoblastoma (TRB) is a rare condition characterized by an intracranial neuroblastic tumor associated with bilateral or unilateral retinoblastoma (RB). The outcome is almost always fatal. An 18-month-old patient with familial bilateral RB was referred for a pineal lesion detected on a screening by magnetic resonance imaging.

Teratoma with a malignant somatic component in pediatric patients: the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) experience.

Background: Teratoma with a malignant somatic component (TMSC) is rare but described in adults, whereas information on pediatric presentation is sparse.

Procedure: The Associazione Italiana Ematologia Oncologia Pediatrica identified 14 cases of TMSC. Clinical files and pathology specimens were reviewed.

Gefitinib in combination with oral topotecan and cyclophosphamide in relapsed neuroblastoma: pharmacological rationale and clinical response.

Aim: Activity and toxiciy of gefitinib in combination with topotecan and cyclophosphamide (CPA) were evaluated in a case-series of relapsed neuroblastoma (NB) patients. The in vitro activity of the combination was also assessed.

Procedure: Gefitinib (250 mg/day), topotecan (0.

A multimodal strategy based on surgery, radiotherapy, ICE regimen and high dose chemotherapy in atypical teratoid/rhabdoid tumours: a single institution experience.

Purpose: Atypical Teratoid/Rhabdoid Tumour is a rare and aggressive childhood tumour. The outcome of a series treated with the same multimodal strategy was reported.

Patients: The patients were treated with surgery, 2 courses of ifosfamide/carboplatin/etoposide(ICE), 2 courses of cyclophosphamide/etoposide/carboplatino/thiotepa (CECAT) or 2 other ICE courses, high dose chemotherapy (HDC) and radiotherapy.

Prolonged response to oral gefitinib, cyclophosphamide, and topotecan in heavily pretreated relapsed stage 4 neuroblastoma: a case report.

A girl with metastatic neuroblastoma diagnosed at 4 years of age experienced an early disseminated relapse after high-dose chemotherapy. After reinduction, compassionate treatment with gefitinib (250 mg/d fixed dose) with oral topotecan (0.8 mg/m(2)/d) and cyclophosphamide (50 mg/m(2)/d) for 14 consecutive days, each course repeated every 28 days, was administered.

High histologic and overall response to dose intensification of ifosfamide, carboplatin, and etoposide with cyclophosphamide, doxorubicin, and vincristine in patients with high-risk Ewing sarcoma family tumors: the Bambino Gesù Children's Hospital experience.

Background: Ewing sarcoma (ES) and extraosseous ES/primitive neuroectodermal tumors (PNET) share histopathologic features of the ES family of tumors (ESFT). The authors report on their results from a regimen of ifosfamide, carboplatin, and etoposide (ICE) with cyclophosphamide, doxorubicin, and vincristine (CAV) dose intensification in patients with high-risk ESFT.

Methods: Since 1990, patients with ESFT and with 1 or more of the following risk factors were reviewed: tumor volume > 200 mL, tumor site with a poor prognosis, and pulmonary and/or bone marrow metastases.

Antibiotic lock with vancomycin and urokinase can successfully treat colonized central venous catheters in pediatric cancer patients.

We used an antibiotic lock technique with vancomycin in combination with urokinase in 10 consecutive eligible children with Gram-positive catheter-related bacteremia persisting after appropriate intravenous antibiotics. Treatment was successful in sterilizing all colonized central venous catheters, avoiding device removal and delay of further chemotherapy. The antibiotic lock technique may represent a safe and effective therapeutic option in patients with selected, uncomplicated catheter-related bacteremias resistant to systemic antimicrobial therapy, particularly when maintaining a venous access is mandatory.
