A total of 67 pHLH patients were included, with a median age of 4.3 years. Our findings revealed distinct genetic mutation distributions between CNS-pHLH and pHLH without CNS involvement; specifically, CNS-pHLH patients had significantly fewer XIAP mutations but more PRF1 mutations (P=0.006 and 0.002, respectively). In addition, the 3-year overall survival (OS) rate for CNS-pHLH patients was markedly lower compared with those without CNS involvement (50.2%±18.42% vs. 93.3%±9.02%, P<0.001). Hematopoietic stem cell transplantation (HSCT) was strongly associated with better prognosis in CNS-pHLH patients, yielding a 3-year OS of 82.0%±23.91% in transplanted patients, significantly higher than the 28.6%±19.40% in nontransplanted patients (P<0.001). Furthermore, a Cox regression analysis identified PRF1 mutation, cerebrospinal fluid (CSF) soluble CD25 levels above 280 pg/mL, and elevated ferritin levels as independent risk factors for poor 3-year event-free survival (EFS) in CNS-pHLH (P<0.05).

What started as a call to arms after the AYA-specific Progress Review Group (PRG) in 2006 became a national initiative, which has had successes and failures nationally, regionally, and locally in trying to move the needle for a group of patients that continues to straddle both the pediatric and adult oncology worlds. Back in 2015, we described the field as in its late adolescence, still trying to define itself. With this 2-part review, we hope to demonstrate that as a subspecialty it has grown up but is still trying to firmly establish its place in the larger world of oncology, much like a young adult that has moved away from home and is establishing its own identity in a changing world.
