RESUMEN

AIM: Validated clinical decision rules on neuroimaging are not available for children who are evaluated more than 24 h after a minor head trauma. We compared clinically important traumatic brain injuries in children who presented with a minor head trauma within or after 24 h. METHODS: This was a retrospective analysis of patients aged 0-17 years, who were evaluated for minor head traumas by five paediatric emergency departments in Northern Italy between January 2019 and June 2020. Children with clinically important traumatic brain injuries were divided into those who had presented within and after 24 h. RESULTS: The study comprised 5981 children (59.9% boys), with a median age of 2 years, including 243 (4.1%) who had presented more than 24 h after their minor head trauma. Neuroimaging was performed on 448 (7.5%) patients and the time of presentation had no impact on the rates of clinically important traumatic brain injuries. Multiple logistic regression did not show any association between clinically important traumatic brain injuries and late presentation. CONCLUSION: Delayed presentation to a paediatric emergency department after a minor head trauma did not alter the risk of clinically important traumatic brain injuries and the same neuroimaging rules could apply.

RESUMEN

OBJECTIVE: To describe a series of cutaneous melanoma in children collected by the Italian Rare Tumors in Pediatric Age project. STUDY DESIGN: From 2000 to 2012, 54 patients younger than 18 years of age were prospectively registered and treated at 12 Italian pediatric centers on the basis of the same diagnostic/therapeutic recommendations and with the same forms to record clinical data. RESULTS: Considering the estimated annual incidence in Italy, the registered cases accounted for 30% of those expected in children and 10% of adolescents. Clinically, 47% of the tumors were amelanotic and 81% were raised, 39% of cases had tumor thickness >2 mm, and 36% had lymph node involvement. For the whole series, 5-year event-free survival and overall survival rates were 75.2% and 84.6%, respectively. Patient survival correlated with tumor stage and ulceration. No relapses were recorded for T1-2 (thickness <2 mm), N0, and stage 0-I-II cases. CONCLUSION: We suggest that the variables influencing survival in children with melanoma are the same as for adults, the clinical approach used in adults is feasible in children, and pediatric cases are more likely to have advanced disease at diagnosis but similar survival. New effective drugs are needed for advanced disease, and biological studies and international cooperative schemes are warranted.

RESUMEN

BACKGROUND: A protocol for the intensive treatment of non-cerebellar PNET (CNS-PNET) combining chemotherapy and radiotherapy was launched in 2000. Efforts were subsequently made to improve the prognosis and to de-escalate the treatment for selected patient groups. PROCEDURE: Twenty-eight consecutive patients were enrolled for a high-dose drug schedule (methotrexate, etoposide, cyclophosphamide, and carboplatin ± vincristine), followed by hyperfractionated accelerated CSI (HART-CSI) at total doses of 31-39 Gy, depending on the patient's age, with two high-dose thiotepa courses following CSI. After the first 15 patients had been treated, craniospinal irradiation (CSI) was replaced with focal radiotherapy (RT) for selected cases (non-metastatic and not progressing during induction chemotherapy). Eight of the 28 children received the same chemotherapy but conventionally fractionated focal RT at 54 Gy. RESULTS: The 5-year progression-free survival (PFS), event-free survival (EFS), and overall survival (OS) rates were 62%, 53%, and 52%, respectively, for the whole series, and 70%, 70%, and 87% for the eight focally irradiated children. Residual disease and metastases were not prognostically significant. In children with residual disease, response to RT was significant (5-year PFS 59% vs. 20%, P = 0.01), while the total dose of CSI was not. There were three treatment-related toxic events. Relapses were local in seven cases (including two of the eight focally irradiated patients), and both local and disseminated in 2. CONCLUSIONS: This intensive schedule enabled treatment stratification for the purposes of radiation, thereby sparing some children full-dose CSI. Local control is the main goal of treatment for CNS-PNET.

RESUMEN

Pediatric fibroblastic-myofibroblastic tumors of intermediate prognosis are locally aggressive tumors that rarely metastasize. They are potentially curable, but managing them is often a challenge in terms of their correct diagnosis and appropriate treatment. This paper reviews the most recent biological findings and latest novelties in the multidisciplinary treatment of childhood desmoid-type fibromatoses, infantile fibrosarcoma and inflammatory myofibroblastic tumor.

RESUMEN

BACKGROUND: The awareness that adolescents can have cancer is probably insufficient, not only among teenagers and their families, but also among physicians, and adolescent patients are reportedly often referred to qualified cancer institutes after a considerable delay. PROCEDURE: A prospective series of 425 patients (28% of them adolescents) with solid tumors was analyzed to investigate the correlation between symptom interval and age, and the different contributions to symptom interval in terms of the time from symptom onset to the first contact with a doctor (patient delay), referral to the oncologist (referral delay), and final diagnosis (oncologist delay). RESULTS: The median symptom interval was 47 days for 0 to 14-year-old patients and 137 for those ≥15 years (P < 0.001). The greatest delay in the adolescent group related to the patient delay (63.3% of the total symptom interval). CONCLUSION: Adolescents are often diagnosed with longer delay as compared to children. The main contribution to symptom interval in adolescents appears to be due to the time they first go to a doctor; however, also the time taken by the physician to the patient to a specialist (oncologist or surgeon) able to define the diagnosis of cancer was longer for adolescents than for younger patients.

RESUMEN

Synovial sarcoma and rhabdomyosarcoma are two high-grade soft tissue sarcoma subtypes that occur in adolescents and young adults. Managing these malignancies in patients in this age bracket poses various clinical problems, partly because different therapeutic approaches are sometimes adopted by pediatric and adult oncologists, even though they are dealing with the same condition. In this review, the doubts concerning how best to manage soft tissue sarcomas in patients between pediatric and adult ages lead up to a more general discussion of the issue of access to optimal cancer services for adolescents and young adults - a subset of patients acknowledged as being under-represented in clinical trials on therapies that may improve their outcome. The situation in Italy is described, along with action taken in an effort to bridge the gap and implement specific programs tailored to these patients.

RESUMEN

This paper reports on two cases of adolescents with paratesticular embryonal rhabdomyosarcoma completely resected at diagnosis (a pediatric disease potentially curable in more than 90% of cases) and treated at adult facilities with a strategy used for adult soft tissue sarcomas. The final outcome of the two patients was dismal after they received a treatment inconsistent with pediatric protocols. The cases reported here give us a chance to turn the spotlight on a crucial issue-the referral of adolescents with pediatric-type tumors and their access to experienced centers and clinical trials.
