ABSTRACT
Background: Palliative care (PC) is an integral part of cancer treatment. However, data on service availability is limited in childhood cancers. Aim: To describe the availability of PC services in paediatric oncology centres across Europe, and to identify barriers and facilitators for implementing and providing paediatric palliative care (PPC). Methods: Paediatric oncology centres across Europe were invited to complete an online questionnaire. Results: A total of 158 paediatric oncology centres from 27 European countries participated. More than half of the centres (n=102, 64.6%) reported offering specialised PPC (defined as 24/7 coverage services with specialized physician and a multidisciplinary team). Most centres included a multidisciplinary care team (n=123, 80.9%) and PC at home (n=105, 69.1%). In 38.7% centres, service capacity was reported to be lower than demand. In most centres, PC consultation was initiated for a refractory neoplasm (n=126, 81.2%). Few centres (n=11, 7.1%) offered PC consultation at the time of a new cancer diagnosis. Eighty-two centres (52.6%) reported having bereavement services. Negative parental perception (n=99, 64.7%) and late referrals (n=91, 59.5%) were major barriers to implementation perceived by health care providers. Conclusion: Our results suggest that specialised PPC is available in more than half of paediatric oncology settings across Europe. Although half have had PPC available for >10 years, many cannot fulfil the demand for service. Barriers to implementation (i.e., parental education, staff training) should be addressed, with resources and services further expanded to cover the demand for PPC, including bereavement care.
ABSTRACT
PURPOSE: To evaluate the prognostic impact of large cell/anaplastic (LC/A) histology together with molecular and clinical risk factors in childhood medulloblastoma. METHODS: Three consecutive prospective medulloblastoma trials were screened for patients with the histological diagnosis of LC/A medulloblastoma. Tumors were considered as LC/A if they displayed areas of severe cytological anaplasia or a significant or predominant large cell component. Histology was centrally confirmed. Genomic DNA amplification of c-myc and n-myc, and mRNA expression of c-myc and trkC were analyzed. RESULTS: Twenty-eight patients with LC/A medulloblastoma with a median age of 6.1 years (1.4-16.5 years) and a median follow-up of 4.5 years were identified (5% of all medulloblastoma). Four-year event-free (EFS) and overall survival (OS) were 58% and 67%. Young age and metastases (n = 13, 4-year EFS 31% vs. 82% in 15 children >4 years and without metastases, P = 0.001), large cell histology (n = 9, 4-year EFS 22% vs. 75%, P = 0.005) and c-myc amplification (n = 9, 4-year EFS 22% vs. 89%, P < 0.0001) were negative prognostic factors. C-myc amplification was highly correlated with young age (P < 0.001), metastases (P = 0.002) and large cell histology (P = 0.007). Outcome of 12 patients with severely anaplastic tumors without these risk factors was not impaired (4-year EFS 86%). CONCLUSION: In a subgroup of patients without clinical and molecular risk factors outcome was favorable despite severely anaplastic histology. In contrast, c-myc amplification and large-cell histology were associated with an inferior outcome. Intensified treatment strategies should be considered for children with LC/A medulloblastoma and these characteristics.
