Individual Experiences in Four Cancer Patients Following Psilocybin-Assisted Psychotherapy

This case study describes patients (n=4) from a randomised, double-blind, placebo-controlled trial investigating single-dose psilocybin (21mg/70kg) psychotherapy to treat cancer-related anxiety and depression. These four participants’ personal narratives extended beyond the cancer diagnosis itself, frequently revolving around themes of self-compassion and love, acceptance of death, and memories of past trauma.

Abstract

A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 patients with cancer-related anxiety and depression were randomly assigned to treatment with single-dose psilocybin (0.3 mg/kg) or niacin in conjunction with psychotherapy. Previously published results of this trial demonstrated that, in conjunction with psychotherapy, moderate-dose psilocybin produced rapid, robust, and enduring anxiolytic, and anti-depressant effects. Here, we illustrate unique clinical courses described by four participants using quantitative measures of acute and persisting effects of psilocybin, anxiety, depression, quality of life, and spiritual well-being, as well as qualitative interviews, written narratives, and clinician notes. Although the content of each psilocybin-assisted experience was unique to each participant, several thematic similarities and differences across the various sessions stood out. These four participants’ personal narratives extended beyond the cancer diagnosis itself, frequently revolving around themes of self-compassion and love, acceptance of death, and memories of past trauma, though the specific details or narrative content differ substantially. The results presented here demonstrate the personalized nature of the subjective experiences elicited through treatment with psilocybin, particularly with respect to the spiritual and/or psychological needs of each patient.

Research Summary of 'Individual Experiences in Four Cancer Patients Following Psilocybin-Assisted Psychotherapy'

Introduction

Research on psychedelic-assisted psychotherapy for cancer-related psychological and existential distress dates back to the 1960s–1970s and included several hundred participants, with reports of improvements in depression, anxiety, fear of dying, quality of life and pain. More recent controlled trials of psilocybin have likewise reported rapid, substantial and sustained reductions in cancer-related anxiety and depression, reductions in existential distress, and changes in orientation toward death. In-depth qualitative work from one such trial identified common experiential themes across participants, but left open questions about the individualized content and clinical courses of treatment responses. Ross and colleagues set out to illustrate the personalised, idiographic aspects of psilocybin-assisted psychotherapy by presenting four case reports drawn from that larger double-blind randomised trial. The aim was to show how distinct subjective experiences map onto clinical change, and to use combined quantitative and qualitative material to highlight psychological processes that could inform future trial design, measures and hypotheses.
