Abstract

Decision making for children and young adults with incurable high grade gliomas (HGGs), like diffuse intrinsic pontine glioma (DIPG) or glioblastoma multiforme (GBM), is difficult, complex, and ethically challenging. 

A longitudinal, qualitative study was completed from April 2017 to February 2018 to evaluate factors that play into decision making for children and young adults with HGGs, their families and clinicians.  Twenty four of 36 eligible patients were approached.  Seventeen enrolled and two withdrew for transfer of care and unavailable, consenting interpreter.  Key decision making visits (e.g. MRI reviews) and semi-structured interviews with parents and/or patients were serially audio-recorded.  Field notes from clinician meetings, chart notes, and oncologist questionnaires were obtained.  Discussions and interviews were transcribed, coded, and analyzed manually and with MAXQDA software until thematic saturation. 

An average of 5 encounters, or 2.5 hours, were recorded per patient. Parent and patient interview themes included 1) hope (for a cure, prolonged life, and quality of life), 2) importance of physician recommendations, 3) importance of support systems (family, community, social media), 4) food (as cancer etiology, intervention) 5) finances (personal, research funding), 6) communication (with medical providers, family, community), 7) death, and 8) God (beliefs, prayer, existential questions).  While patients, families and physicians all hoped for treatment efficacy, they balanced it with the known poor prognosis. Physicians consistently hoped for patients to live as long as possible as well as possible.  Patients and families transitioned more slowly to this hope.  Clinician attempts to preserve hope differed between oncologists and palliative care specialists. 

From these results, decisions made in this setting are multi-factorial, ultimately reflecting the competing values of decision makers.  Optimism about treatment is held in tension with poor prognosis, allowing for functional hope for patients and families.  Acknowledging shifting hopes of patients and families allows for changes in goals of care and shared decision making. 

Principlism is used to ethically analyze the decision making process, beginning with who makes the decisions to what decisions are made.  A clinician communication guide was developed to aid in the multiple difficult conversations for children and young adults with HGGs.
