RESUMEN
OBJECTIVE: This study aimed to evaluate management and prognosis in children with pheochromocytoma who were treated at an Egyptian tertiary center. METHODS: The authors conducted an 8-year retrospective analysis for 17 patients who were presented from January 2013 to January 2021. Clinical criteria, operative details, and follow-up data were assessed. Overall (OS) and event-free survival (EFS) were estimated by the Kaplan-Meier method. An event was assigned with the occurrence of recurrence or metachronous disease, or death. RESULTS: Median age at diagnosis was 14 years (range: 6-17.5 years). Ten patients (58.8%) were males and seven (41.2%) were females. Hypertension-related symptoms were the main presentations in 15 patients (88%). None of the included children underwent genetic testing. Sixteen patients (94%) had unilateral tumors (right side: 12), whereas only one was presented with bilateral masses. The median tumor size was 7 cm (range: 4-9 cm). Metastatic workup did not reveal any metastatic lesions. All patients underwent open adrenalectomy, and clinical manifestations were completely resolved after surgery. Adjuvant therapy was not administered to any patient. There were no deaths or relapses at a median follow-up time of 40 months, whilst two children had metachronous disease after primary resection. Both were managed by adrenal-sparing surgery, and they achieved a second complete remission thereafter. Five-year OS and EFS were 100% and 88%, respectively. CONCLUSIONS: Complete surgical resection achieves excellent clinical and survival outcomes for pheochromocytoma in children. Meticulous, long-term follow-up is imperative for early detection of metachronous disease to facilitate adrenal-sparing surgery. Genetic assessment for patients and their families is essential; however, it was not available at our institution.

INTRODUCTION: This study aimed to investigate potential factors contributing to local recurrence after surgical resection of hepatoblastoma (HB). MATERIALS AND METHODS: This retrospective study involving all patients with HB who underwent nontransplant surgery at our tertiary center between July 2007 and July 2018. Data were analyzed regarding microscopic surgical resection margin, tumor multifocality and extracapsular tumor extension in correlation with local recurrence. These relations were assessed by logistic regression. RESULTS: The study included 133 patients with a median age of 1.3 years (range: 0.5-12.8 years). They were classified into 99 cases (74.44%) standard risk and 34 cases (25.56%) high risk. Delayed surgical resection was adopted in all patients. Follow-up to July 2019 revealed that 23 patients (23/133, 17.3%) developed local recurrence, whereas the remaining 110 were locally disease free. Microscopic positive margin (R1) was detected in 29 patients, 8 of them had local recurrence (p = 0.097). Regarding tumor multifocality, there were 12 patients who had multifocal lesions, 3 of them developed local recurrence (p = 0.459). Forty-four patients had extracapsular tumor extension in their pathological reports, 12 of them had local recurrence (p = 0.032). CONCLUSION: Extracapsular tumor extension was a significant prognostic factor of local recurrence after surgical resection of HB. R1 margin does not necessarily require a second resection, and it could achieve accepted results when combined with adjuvant platinum-based chemotherapy. However, patients who are not eligible for surgical resection must be transferred for primary transplantation to obtain favorable outcome.

BACKGROUND: The aim of this prospective, comparative, randomized study was to compare the inhalational anesthetics isoflurane, sevoflurane, and desflurane in pediatric patients undergoing craniotomy for excision of supratentorial tumors. We assessed early postoperative recovery outcome, intraoperative hemodynamics, and degree of brain swelling, as well as postoperative vomiting and shivering. METHODS: Sixty patients scheduled for supratentorial brain tumor excision, were randomly allocated into 1 of 3 groups (20 patients each); isoflurane, sevoflurane, and desflurane group. After IV induction of anesthesia, maintenance was achieved using the inhalational anesthetic according to the allocated group. Tracheal extubation time was the primary endpoint. The secondary endpoints included: emergence time and the interval time needed to reach Aldrete score ≥9, intraoperative degree of brain swelling, intraoperative heart rate and mean arterial blood pressure, as well as postoperative vomiting and shivering. RESULTS: The mean emergence time, extubation time, and the interval required to reach Aldrete score 9 were significantly shorter in the desflurane and sevoflurane groups than the isoflurane group. No statistically significant changes in the 3 groups regarding intraoperative brain swelling, hemodynamics, and postoperative shivering or vomiting were noted. CONCLUSIONS: Desflurane and sevoflurane can be used to facilitate early emergence from anesthesia in neurosurgical pediatric patients. Emergence times are shorter with desflurane or sevoflurane than with isoflurane. The patients who received desflurane or sevoflurane have similar intraoperative and postoperative incidence of adverse effects compared with those who received isoflurane. Thus, desflurane and sevoflurane can be considered as suitable for emergence in pediatric neurosurgical anesthesia.
