Insights
Delayed presentation and early deaths significantly impact childhood cancer survival. Improving early diagnosis and supportive care is crucial, especially for hematological malignancies, to enhance treatment outcomes.
Area of Science:
- Pediatric Oncology
- Cancer Epidemiology
- Clinical Research
Background:
- Childhood cancer patients face risks of rapid deterioration and death before diagnosis.
- Delayed presentation and early mortality are critical challenges in pediatric oncology.
- Understanding mortality patterns across different childhood cancer types is essential.
Purpose of the Study:
- To investigate delayed presentation and early deaths in children with suspected cancer.
- To analyze mortality types and causes in pediatric cancer patients.
- To identify factors contributing to poor outcomes in childhood malignancies.
Main Methods:
- Retrospective review of 502 pediatric oncology patients admitted between 2006-2010.
- Analysis of patient demographics, diagnosis, symptoms, and time intervals (symptoms to visit, admission to death).
- Categorization of mortality causes (treatment-related vs. disease-related) and specific causes (infection, respiratory failure, etc.).
Main Results:
- 47.4% of patients (238/502) died; 66% of deaths were treatment-related mortality (TRM), primarily due to infection (60%).
- Hematological malignancies had higher TRM (81%) compared to solid tumors (primarily disease-related, 70%).
- Early death (<48 hours post-admission) occurred in 5% of patients; mean delay from symptom onset to first visit was 67 days.
Conclusions:
- Delayed presentation significantly contributes to early deaths in pediatric cancer patients.
- Enhanced early diagnosis and supportive care are vital for improving survival rates.
- Specific attention to hematological malignancies is needed to reduce mortality.
Introduction:
Children with suspected cancer may succumb to their bad condition shortly after admission, even before a definitive diagnosis can be reached. We aimed to address the issue of delayed presentation and early deaths among children suspected of having cancer. We analyzed also the types and causes of mortalities across different tumor types.
Materials And Methods:
A retrospective review of reports from newly admitted patients between 2006 and 2010 at the pediatric oncology department of the South Egypt Cancer Institute (SECI) was done. Parameters included age, gender, diagnosis, symptoms, the interval between initial symptoms and the first visit to SECI, the duration from admission to death, and the cause of death.
Results:
Among the 502 patients with confirmed malignancies, 238 (47.4%) succumbed. Causes of death were predominantly treatment-related mortalities (TRM) (66%). Mortalities within hematological malignancies were mainly TRM (81%), whereas solid tumors were primarily disease-related (70%), p <0.0001. The leading causes of TRM was infection (60%). About 5% of patients experienced early death within 48 hours after presenting to SECI. The mean duration from initial symptoms to the first SECI visit was 67 days, and the period from admission to death averaged 27 hours. Common initial symptoms included abdominal swelling (29.6%), or fever (26%). The leading causes of death were respiratory failure (29.6%), tumor lysis syndrome (22%), or septicemia (22%).
Conclusions:
Delayed presentation leading to early deaths poses a significant obstacle to the successful treatment of childhood cancers. Early diagnosis and improved supportive care are essential to enhancing the overall survival, particularly in patients with hematologigical malignancies.
