Conclusions
This cross-sectional survey highlighted the current availability of essential specialty expertise and MDTB structures in most PSTUs in Southeast Asian countries. Recent regional initiatives and collaborations have been a clear contributor to these developments. However, the lack of pediatric-trained subspecialists, particularly dedicated pediatric oncology surgeons, and pediatric-trained pathologists and radiologists, remains a gap in the workforce required for capable multidisciplinary care of solid tumors. An extended spectrum of training programs is needed to focus on these subspecialties as well.
