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.

A single 25 mg dose of psilocybin combined with psychotherapy provided long-term relief from depression and anxiety in patients with cancer. Two years after treatment, over half of the 28 patients showed significant reduction in depression, with an average 15-point drop on the Montgomery Asberg Depression Rating Scale, and half maintained that improvement. Nearly half also experienced significant anxiety reduction, averaging a 13.9-point decrease on the Hamilton Anxiety Rating Scale, with 43% sustaining the benefit. The findings indicate a potentially paradigm-changing alternative to standard antidepressants for this population.

Meaning-centered psychotherapy (MCP) is a manualized, brief intervention that enhances meaning and purpose and appears to be a natural therapeutic partner for psilocybin-assisted therapy (PAT) in patients with cancer and major depressive disorder. In a phase 2 open-label trial, seven patients (ages 53-80) and six therapists (with 9-44 years of experience) participated in surveys and focus groups to adapt MCP for psilocybin. Focus groups highlighted the value of psilocybin experiences, group support, and MCP both separately and together. A 5-session model called MCP-PSIL was developed. The group format was emphasized, though individual MCP may be appropriate in some cases.
