Management and successful use of vascular access are critical issues in pediatric patients affected by malignancies. Prolonged course of disease, complex and various treatment protocols require long-lasting vascular access providing adequate tools to administrate those therapies and to collect routine blood sampling without painful and repeated venipuncture. For these reasons, central venous catheters are currently an important component in pediatric onco-hematological care, with a direct influence on outcome. Indeed, there are peculiar issues (techniques of insertion, management, complications etc.) which must be well-known in order to improve the outcome and the quality of life of children with cancer.
Purpose The removal of long-term central venous catheters (CVCs) is not performed according to evidence-based guidelines, thus conveying the message that it is a procedure of secondary importance. Our study aims at comparing the experience at Bambino Gesù Pediatric Hospital before and after the implementation of a dedicated protocol and the identification of a specific area to perform such a procedure under the so-called nonoperating room anesthesia (NORA). Methods Starting on January 1, 2010, an appropriate protocol regarding long-term CVC removal was applied. Then, data from all patients who underwent CVC removal under NORA regimen were compared with patients who have undergone the same procedure before the beginning of such protocol in terms of complication rate, duration of procedure, and costs. Results Between January 2010 and December 2012, 266 patients were evaluated for long-term CVC removal under a NORA regimen. Of these, 194 underwent the procedure. In the period from January 2007 to December 2009, 60 out of 82 patients scheduled for elective removal of long-term CVC in the operating theatre were eligible for this study. Median procedure time was 7 min for removal in NORA and 10 min for the operating theatre (p=0.016); no complications occurred. Conclusion Long-term CVC removal is an often-neglected procedure, carrying a small, but definite rate of complications. Our study shows that CVC removal performed in NORA regimen is safe and feasible, also allowing multiple procedures in the same session with prompt management of possible complications and reduction of the anxiety and pain associated with the procedure.
Background: Proper securement of central venous catheters plays an important role in onco-hematological pediatric patients. A new subcutaneously anchored securement device has been recently introduced in the clinical practice, and it has been extensively used in children. Method: In our study, we have retrospectively investigated the safety and the effectiveness of such device, reviewing the experience of three Italian pediatric oncological units. We have considered only tunneled catheters (cuffed or non-cuffed) inserted in children with malignancy; all types of tunneled central catheters were included in the analysis (both centrally and peripherally inserted) as long as they were secured with a subcutaneously anchored device. We investigated the incidence of dislodgment and of other catheter-related complications, with special attention to local adverse effects potentially related to the securement device. Results: We collected data from 311 tunneled catheters of different caliber: 80.4% were centrally inserted central catheters (CICC), 15.4% were peripherally inserted (PICC), and 4.2% were femorally inserted. Approximately half of the catheters (51%) were non-cuffed. Incidence of dislodgment was very low (2.6%) and the incidence of local pain or inflammation potentially related to the securement device was minimal (1.9%). Catheter related bacteremias were below 1 episode/1000 catheter days. No symptomatic catheter related thrombosis was reported. There was no significant difference in complications comparing cuffed versus non-cuffed catheters, or CICCs versus PICCs, or hematologic tumors versus solid tumors. Conclusion: In our retrospective analysis of a vast population of oncological pediatric patients with tunneled central catheters, the subcutaneously anchored securement device was tolerated very well, and it was highly effective in preventing dislodgment, both in cuffed and non-cuffed catheters.
Background:Thyroid gland malignancies are rare in pediatric patients (0.7% of tumors); only 1.8% are observed in patients aged <20 years, with a higher prevalence recorded in women and adolescents. Risk factors include genetic syndromes, MEN disorders, autoimmune diseases, and exposure to ionizing radiation. Radiotherapy is also associated with an increased risk of secondary thyroid cancer. This study describes the clinical features and surgical outcomes of primary and secondary thyroid tumors in pediatric patients.MethodsInstitutional data were collected from eight international surgical oncology centers for pediatric patients with thyroid cancer between 2000 and 2020. Statistical analyses were performed using the GraphPad Prism software.ResultsAmong 255 total cases of thyroid cancer, only 13 (5.1%) were secondary tumors. Primary thyroid malignancies were more likely to be multifocal in origin (odds ratio [OR] 1.993, 95% confidence interval [CI].7466–5.132, p = 0.2323), have bilateral glandular location (OR 2.847, 95% CI.6835–12.68, p = 0.2648), and be metastatic at first diagnosis (OR 1.259, 95% CI.3267–5.696, p > 0.999). Secondary tumors showed a higher incidence of disease relapse (OR 1.556, 95% CI.4579-5.57, p = 0.4525) and surgical complications (OR 2.042, 95% CI 0.7917–5.221, p = 0.1614), including hypoparathyroidism and recurrent laryngeal nerve injury. The overall survival (OS) was 99% at 1 year and 97% after 10 years. No EFS differences were evident between the primary and secondary tumors (chi-square 0.7307, p = 0.39026).ConclusionsThis multicenter study demonstrated excellent survival in pediatric thyroid malignancies. Secondary tumors exhibited greater disease relapse (15.8 vs. 10.5%) and a higher incidence of surgical complications (36.8 vs. 22.2%).
Uterine leiomyomas are rare in the pediatric population with less than 20 cases in adolescences reported in the literature. Furthermore, these masses represent a common presentation of gynecologic tumors with increasing age. We report a case of a 14-year-old female who presented with abdominal pain and increasing abdominal girth. Workup with ultrasound, CT and MRI demonstrated a large pelvic mass. Complete resection by median laparotomy was performed. The mass weighed 5,596 g and was 29.5 cm × 27 cm × 19 cm; the pathological examination confirmed the hypothesis of leiomyoma. The patient remained asymptomatic at 3 months follow up.

The second most common abdominal tumor in children is Wilms’ tumor, and the lung is where it most often metastasizes. The typical metastases are multiple, peripherally located, round, and variable-sized nodules. Atypical patterns are also possible and may create diagnostic challenges, especially in patients treated with chemotherapy. Among these, cavitating metastases are an anecdotal type of atypical secondary lung lesions. Here, we report a case of a chemotherapy-induced cavitating Wilms' tumor pulmonary metastasis discovered during the follow-up for an anaplastic nephroblastoma in a 6-year-old girl. Furthermore, we conducted a review of the existing literature on this exceedingly rare radiological pattern to establish its best management.
