[Treatment of gastrointestinal bleeding in neonates: a case report]. / Scelta terapeutica nelle emorragie intestinali pediatriche: un controverso caso neonatale.

Gastrointestinal bleeding in infants and children is an uncommon and potentially serious problem, but fortunately is usually limited and most cases resolve with close medical attention. The therapeutic criteria is often difficult particularly in neonates. In this work we examine the case of a neonate with serious gastrointestinal bleeding and the delayed treatment for diagnostic difficulties.

Tumor response and toxicity after single high-dose versus standard five-day divided-dose dactinomycin in childhood rhabdomyosarcoma.

This report deals with a randomized prospective multicentric clinical trial in childhood rhabdomyosarcoma (RMS) conducted to evaluate the toxicity and the effectiveness of dactinomycin (ACT-D) administered as high, single doses v five-day, divided doses administered in combination with vincristine (VCR) and cyclophosphamide (CYC). Fifty-five group III evaluable patients (pts) less than 15 years of age with tumor size greater than 5 cm in diameter, without high-risk features of CNS involvement, and 15 group IV RMS pts were randomized to receive VAC as primary chemotherapy (CT): VCR, 1.5 mg/m2 intravenously (IV) days 1 and 8; CYC, 275 mg/m2 IV days 1 through 5; and ACT-D, 0.45 mg/m2 IV days 1 through 5 every 28 days for three cycles (33 pts), or VAC-M: CYC, 150 mg/m2 intramuscularly (IM) days 1 through 7; VCR, 2.0 mg/m2 IV day 8; and ACT-D, 1.7 mg/m2 IV day 8 every 21 days for four cycles (37 pts). Major responses (complete plus partial responses [PR]) were obtained in 67% of the VAC pts and in 70% of the VAC-M pts. Toxic effects were low, and no increased toxicity was observed in pts treated with high, single-dose ACT-D. These results confirm the effectiveness and feasibility of single, high doses of ACT-D with the advantage of requiring less pt hospitalization.

Cancer mortality among relatives of children with soft-tissue sarcoma: a national survey in Italy.

Information was obtained on the living status or cause of death of 2223 close relatives of 195 children with soft-tissue sarcomas (STS) diagnosed under age 15. Three-hundred nine relatives had died, from all causes, before STS diagnosis in the index child. The expected figure estimated from age- and sex-specific mortality rates in Italy was 293.3. Cancer was reported as cause of death in 76 relatives (75.1 expected). Seven grandmothers, 2 aunts, 1 uncle and 0 mothers died from breast cancer vs. 4.6, 0.9, 0.0 and 0.2 expected. Three siblings died from cancer (0.2 expected, P less than 0.01), i.e. STS, ependymoma and non-Hodgkin lymphoma. These results confirm and expand previous observations that STS in children are associated with other cancers, particularly childhood and breast cancer, in members of the same family.

Paratesticular rhabdomyosarcoma in childhood: experience of the Italian Cooperative Study.

The authors report the experience of the Italian Cooperative Study AIEOP-CNR RMS-79 concerning 16 children affected by localized paratesticular rhabdomyosarcoma (15 stage I, 1 stage II). The good results obtained by multidisciplinary treatment suggest a less aggressive approach as regards retroperitoneal lymph node biopsy and chemotherapy.

Metastatic rhabdomyosarcoma and histologically similar tumors in childhood: a retrospective European multi-center analysis.

This is a retrospective analysis of children with metastatic soft tissue sarcoma (STS) registered in the major European STS studies: the SIOP MMT 75, the German CWS 1981 and 1986 studies, the Italian STS study, and the United Kingdom Children's Cancer Study Group centres in Britain. One hundred forty-six patients out of 164 were evaluable in this analysis. The median age was 7 years (1-18) and the male/female ratio was 1.3:1. The median follow-up was 80 months (7-171). The most common site of the primary tumor was the extremity (28%), which correlated well with the high preponderance (39%) of the alveolar type of RMS (aRMS). There was no dominant combination of metastatic sites and the most common single organ with metastasis was the lung (41%). Since the therapy depended on the country and period in which the patient was treated, we did not analyse the outcome and therapy together. Complete remission was achieved in 50% of the cases. Those with aRMS had a good chance of achieving CR (61%) but the majority of these patients relapsed (78%). The median time needed to relapse was 243 days (53 days to 47 months) for all patients. Analysis of the site of the primary tumor showed that the CR rate was best in the GU non-BP site (62%) and worst in PM cases (35%). The overall survival and DFS rate were 18% and 15%, respectively. The GU non-BP patients had a DFS rate of 50%, while the rate for all other sites varied between 12% and 18%. A total of 24 patients remained in CCR. The majority of them had embryonal type of RMS and metastases in only one anatomic site. Our analysis indicates that the best chance of prolonged survival was in metastatic GU non-BP cases, patients with embryonal type RMS, and those with metastases in only one organ. To try to improve the treatment of metastatic STS, a prospective European cooperative study was started in 1989.

Phase II trial of cisplatin and etoposide in children with advanced soft tissue sarcoma: a report from the Italian Cooperative Rhabdomyosarcoma Group.

A phase II multicenter evaluation of cisplatin (90 mg/m2, Day 1) and etoposide (150 mg/m2, Days 2, 3, and 4) in 4-week cycles was carried out in 21 relapsed children with rhabdomyosarcoma (RMS) and six with non-RMS soft tissue sarcomas (NRSTS). Clinical responses were evaluated after four cycles. There were three complete responses (CRs) and four partial responses (PRs) among the 21 patients with RMS and no responses among the patients with NRSTS. The durations of the three CRs and the four PRs were 11, 9, and 8 months, and 5, 2, 2, and 1 month, respectively. Bone marrow and renal toxicity was cumulative and predictable, but not life threatening. The response rate (CR + PR = 33.3%) to cisplatin and etoposide warrants testing as front-line therapy for RMS.

Idarubicin and high-dose cytarabine in the treatment of refractory and relapsed acute lymphoblastic leukemia.

Between August 1985 and April 1989, 88 patients (31 children and 57 adults) with refractory of relapsed acute lymphoblastic leukemia (ALL) were treated in a cooperative Italian trial by an induction schedule of high-dose Cytarabine (HDAra-C) plus Idarubicin (IDA). Complete remission (CR) was achieved in 52 of the 88 patients (59%); 23 patients (26%) did not respond to treatment and 13 (15%) died during induction. The CR rate was significantly affected by the WBC count at the beginning of treatment and by the duration of first CR of the patients treated at first relapse. All of the patients experienced profound myelosuppression; the median time to recovery to neutrophils greater than 0.5 x 10(9)/l was 15 days (range 4-40), and 14 days (range 3-50) to platelets greater than 50 x 10(9)/l. The most common non-hematologic side effects observed were nausea and vomiting (51%), mucositis (40%) and diarrhea (23%). Twenty-one of the 52 patients who achieved CR underwent bone marrow transplantation (BMT), 16 autologous and 5 allogeneic. Eleven patients relapsed at a median of 4 months (range 1-31) after the transplantation, and three patients died while in CR. Seven patients have been in continuous CR (CCR) for a median of 36 months (range 26-42 months). Thirty-one patients were not entered in the BMT program: for two adults it was too early, three adults died in CR and 25 patients relapsed at a median of four months (range 1-25). Only one adult is still in CCR at 33 months.(ABSTRACT TRUNCATED AT 250 WORDS)
