Abstract

In children under the age of 3 years, the most common solid tumors are brain tumors. Low grade astrocytomas represent 30-40 % of brain tumours in this age group. This study reviewed the incidence, characteristics, therapy, and outcome of children less than 36 months of age diagnosed with a low grade astrocytoma from 1990 to 2005 in Canada. A data bank was established using data collected from Canadian pediatric oncology centers on children less than age 3 diagnosed with brain tumors between 1990 and 2005. Cases of low grade astrocytoma were extracted from this data bank and their characteristics summarized. From the 579 cases in the data bank, 153 cases of low grade astrocytoma (26 %) were identified. The mean duration of symptoms prior to presentation was 13 weeks, and 53 % of patients underwent a greater than 90 % resection of their tumor, while 30 % underwent 10-90 % resection. Seventy-one percent of patients received no further therapy after surgery and of the 45 who received therapy following surgery, 43 received chemotherapy, and 5 received radiation therapy. Sixty-eight patients had recurrence or progression of their tumor. Eighty-seven percent of patients were alive at the time of the survey with a 2 year survival rate of 95.3 ± 1.8 %, 5 year survival rate of 93.1 ± 2.1 % and 10 year survival rate of 89.1 ± 2.8 %. The 5 year survival rate for Canadian children less than 36 months of age with a low grade astrocytoma was 93.0 ± 2.8 % which is similar to that for older children with this tumor.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 May 2015.
All research outputs
#9,836,885
of 12,317,289 outputs
Outputs from Journal of Neuro-Oncology
#1,124
of 1,806 outputs
Outputs of similar age
#162,514
of 231,558 outputs
Outputs of similar age from Journal of Neuro-Oncology
#34
of 96 outputs
Altmetric has tracked 12,317,289 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,806 research outputs from this source. They receive a mean Attention Score of 2.8. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 231,558 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 96 others from the same source and published within six weeks on either side of this one. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
