Why are brain tumours still being missed?

Area of Science:

• Pediatric Oncology
• Neurology
• Clinical Diagnosis

Background:

• Primary brain tumors are a significant concern in pediatric oncology.
• Timely diagnosis is crucial for effective treatment and improved outcomes in children.
• Previous studies suggest diagnostic delays can occur, but specific factors require further investigation.

Purpose of the Study:

• To investigate the presentation of symptoms in children with primary brain tumors.
• To identify reasons contributing to delays in the diagnosis of pediatric brain tumors.
• To analyze the prediagnosis period, including symptom duration and healthcare consultations.

Main Methods:

• Retrospective review of medical case notes for 74 children with primary brain tumors.
• Interviews with parents of affected children.
• Administration of psychological questionnaires to parents.
• Analysis of clinical history duration, symptom frequency, and consultation patterns.

Main Results:

• The mean clinical history duration was 20.0 weeks.
• Common presenting symptoms included vomiting (65%) and headache (64%).
• Personality changes (47%) were frequent; 24% were initially diagnosed with migraine, and 15% with psychological causes.
• Children averaged 4.6 consultations before diagnosis, with one quarter presenting with altered consciousness.

Conclusions:

• Diagnostic delays for pediatric brain tumors remain a challenge.
• Nonspecific symptoms, such as headaches and vomiting, and the high incidence of psychological symptoms can confound clinical assessment.
• Strong parental concern does not always expedite diagnosis, highlighting the need for improved diagnostic pathways.
