“…This slight prevalence of males over females reflects the gender distribution of the population at risk, the same was found in a Kuwaiti study [13], where male slight preponderance was reported. In another study [14], where the male-tofemale ratio was 1:3, indicated that the pediatric brain tumors were more prevalent in males than in females and other studies found that too [1,15,18].…”

Background: Primary intracranial tumors are the second most common type of pediatric malignancies. Brain tumors account for between 15% and 25% of all childhood malignancies; they have poorer survival rates than hematological malignancies. Intracranial tumors differ throughout childhood stages in their histological types, the location of the tumor and gender distribution. The aim of this study was to investigate the histological types of pediatric brain tumors to gender distribution.

“…In the recently reported series of primary pediatric brain tumors in children, supratentorial tumors predominated over infratentorial tumors. 14,16,17 By using chi-square test, statistical comparison of relative incidence of tumors in these series was performed (data not shown). Except choroid plexus tumor and pineal parenchymal tumor, significant statistical difference (P Ͻ 0.05) of relative incidence existed in astrocytic tumor, medulloblastoma, germ cell tumor, craniopharyngioma, ependymoma, and oligodendroglioma.…”

MR‐guided transrectal prostate biopsy is currently a time‐consuming procedure because the imaging slice is often manually realigned with the biopsy needle during lesion targeting. In this work a pulse sequence is presented that automatically follows a passive marker attached to a dedicated MR biopsy device holder, thus providing an alternative to existing active tracking methods. In two orthogonal tracking FLASH images of the marker the position of the needle axis is automatically identified using a phase‐only cross‐correlation (POCC) algorithm. The position information is then used to realign a trueFISP imaging slice in real time. In phantom experiments the sensitivity of this technique to initial misalignments of the marker and to the signal‐to‐noise ratio was evaluated. In several puncture experiments the precision of the needle placement was analyzed. The POCC algorithm allowed for a precise identification of the marker in the images even under severe initial misalignments of up to 45°. At a frame rate 1 image/s a precision of the needle placement of 1.5 ± 1.1 mm could be achieved. Magn Reson Med 59:1043–1050, 2008. © 2008 Wiley‐Liss, Inc.

“…Some previous studies have shown higher rates of intracranial GCTs in Asians compared with those in the Western population (Cho et al, 2002; Committee of Brain Tumor Registry of Japan 2003; Wong et al, 2005;Park et al, 2008). However, a recent report indicates that Japan has a similar rate of intracranial GCTs as does the United States (McCarthy et al, 2012).…”

Pre-pubertal and adolescent germ cell neoplasms in Taiwan: time trends and geographic variation

et al. 2015

SUMMARYEvidence from our previous study suggested that the incidence of germ cell neoplasms in children and adolescents is increasing. The objectives of this analysis were to quantify this trend in patients aged 0-9 and 10-19 years (pre-pubertal and adolescent groups, respectively) and compare rates in Taiwan according to geographic distribution. Germ cell neoplasm frequencies among 1267 patients aged 0-19 years spanning 1995-2009 were obtained from the population-based Taiwan Cancer Registry. The incidence patterns according to sex, age, disease subgroup, and geographic distribution were analyzed. The incidence rates in the pre-pubertal and adolescent groups were 10.58 and 16.06 per million person-years, respectively. The overall rates increased significantly by 3.2% annually in the adolescent group during the 15-year study period, and increased only among the males. In contrast, no change in trend was observed in the pre-pubertal group. Subgroup analysis showed significant upward trends in the incidence rates of intracranial/intraspinal and testicular germ cell tumors (GCTs) in the adolescent males and extracranial/extragonadal GCTs in the pre-pubertal boys. The most striking differences between the study population and white Americans were that the rates of testicular GCTs were 5-fold higher and 4-fold lower in the Taiwanese pre-pubertal and adolescent groups, respectively. Significantly higher rates were found in Hualien and Chiayi Counties compared with the other areas of Taiwan. The upward trend of testicular GCTs in the adolescent males is consistent with findings from Western countries. The underlying causes that led to the high rate of testicular GCTs in the pre-pubertal boys and significantly higher rates in specific counties warrant further investigation.

Pediatric brain tumors: statistics of SNUH, Korea (1959–2000)

Abstract: The relative incidences of germ cell tumors, neuronal tumors, and oligodendroglial tumors increased after the introduction of magnetic resonance imaging (MRI). In contrast, the incidence rates of medulloblastomas and ependymal tumors decreased.
