ackground and Objectives: More than half of
patients with neuroblastoma were in stage 4 with
metastatic disease at diagnosis, leading to high
morbidity and mortality rates. We aimed to study the
survival outcome of the patients who had stage 4
neuroblastoma at Srinagarind Hospital. Prognostic
factors for survival were also determined.
Methods: A retrospective cohort review medical
records of stage 4 neuroblastoma patients, from 2006
to 2015 at Srinagarind Hospital, Khon Kaen University.
Using survival analysis for survival outcome and
Cox-regression analysis for prognostic factors.
Results: 61 patients, 32 male (52%), 29 female (47%)
were analyzed. Median age of patients was 4 years.
21 patients were categorized in unresectable group,
while 38 were resectable which consisted of complete
and incomplete resection (25 and 13 cases, respectively).
In overall mortality data, 43 patients (72%)
died after diagnosis. The mortality rates of
unresectable complete resection and incomplete
resection groups were 2.7%, 2.36%, and 1.6%,
respectively. The median survival times of
unresectable, complete resection, incomplete
resection group was 11.43, 23.10, and 35.87 months,
respectively. There were no statistically significant
differences of survival experience between resectable
and unresectable groups (p = 0.239), between
complete resection and unresectable groups (p =
0.524), and between incomplete resection and
unresectable group (p = 0.149).
