A single 25-mg dose of psilocybin, administered alongside one-to-one and group therapeutic support, was safe and feasible for patients with curable and noncurable cancer who also had major depressive disorder. In a phase 2 open-label trial with 30 participants, no serious adverse events or suicidality occurred, and mild side effects like nausea and headache were as expected. Depression severity scores dropped by an average of 19.1 points from baseline to eight weeks after treatment. Eighty percent of participants showed a sustained response, and half achieved full remission of depressive symptoms by week one that lasted for eight weeks. The group-oriented format and compact delivery in a community cancer center may add to therapeutic gains.

Group psychedelic-assisted therapy, compared with individual therapy, reduces clinician costs by 50.9% for MDMA treatment of PTSD and 34.7% for psilocybin treatment of major depressive disorder, saving $3,467 and $981 per patient respectively. Using 2023 data from two trial sites and published prevalence estimates, treating all eligible U.S. adults with PTSD or MDD over ten years with group therapy would require 6,711 fewer full-time clinicians for MDMA-PTSD and 1,159 fewer for psilocybin-MDD, saving up to $10.3 billion and $2.0 billion. Adopting group protocols could lower costs, ease clinician shortages, and expand patient access.

Psilocybin-assisted therapy (PAT) is promising for cancer-related depression, but little is known about how the therapeutic context affects patient experiences. In interviews with 28 patients with cancer and depression who participated in a clinical trial, participants described the psilocybin experience as intense and demanding. Therapeutic benefits were closely tied to their ability to "surrender"—accepting and remaining open to the experience's intensity and unpredictability. A safe, supportive, and ethical environment was critical for trust and engagement. Preparation and integration were key to maximizing benefit. Music played a variable role, sometimes enhancing and other times distracting. The clinical setting provided safety, while ceremonial elements added meaning.

Patients with cancer and depression describe their cancer experience as deepening their awareness of mortality and prompting them to reprioritize relationships and efforts. In a trial of psilocybin-assisted group therapy, participants sought not only relief from depression but also a new perspective on existential worries and spiritual resources. After treatment, they reported lasting effects including an enhanced sense of meaning, agency, aliveness, and connectedness, describing the experience as a healing, unfolding transformation. The findings illuminate how psilocybin-assisted therapy may address existential suffering and foster personal growth in this population.
