Overview
The psychological challenges faced by patients with incurable cancer and their caregivers include an uncertain future, fear of dying and uncontrollable suffering, grief, and loneliness. In a significant subgroup, this challenge is associated with significant fear and existential distress. This distress can manifest itself, for example, in the form of demoralization, a state of despair and hopelessness in which the possibilities for coping seem exhausted. Although open discussions about fears at the end of life are becoming increasingly important, little is known about how patients with high existential distress can best be supported to promote quality of life.
The aim of the study is to test the effectiveness of the newly developed individual psychotherapy ORPHYS (ShORt-term psychodynamic psychotherapy in serious PHYSical illness) in reducing existential distress. To this end, a randomly selected half of the participants who receive ORPHYS treatment will be compared with a second group who receive the standard routine psycho-oncological treatment TAU (Treatment As Usual). The level of distress caused by demoralization will be used for the comparison. A total of 160 patients with advanced cancer will be included in the study.
Due to improved treatment options, life expectancy for advanced cancer has increased significantly. This means that patients and their families must deal with the existential tension between uncertainty and a focus on life. The treatment is intended to contribute to providing the best possible support for patients who suffer from uncertainty and fears at the end of life.
Description
Background: As improvements in systemic anti-cancer treatments have extended survival, patients with advanced cancer and their family caregivers face the existential tension between engaging in life and coping with uncertainty about illness trajectory and course of treatment. For a subgroup, this tension is associated with overwhelming fear and existential distress. Existential distress is often characterized by demoralization, a state of despair and hopelessness in which coping skills are exhausted and patients are unable to see something positive in the future. Such adjustment difficulties may increase the risk of poor quality of life and suicidality, as well as impair prognostic awareness and patient-clinician communication. Despite growing interest in open conversations about end-of-life issues, little is known about how clinicians can best support patients experiencing high levels of existential distress in order to facilitate psychological adaptation at the end of life.
Objective: To evaluate the effectiveness of ORPHYS (ShORt-term psychodynamic psychotherapy in serious PHYSical illness) in a pragmatic randomized controlled trial. The intervention group receives 15-31 sessions of ORPHYS, a manualized individual psychotherapy that flexibly integrates uncovering and holding treatment elements. The control group receives usual psycho-oncological care (TAU). The primary outcome is demoralization as assessed by the Demoralization Scale-II. Secondary outcomes include diagnosis of affective, anxiety and stress-related disorders, death anxiety, dignity-related distress, and quality of life.
Methods: The investigators will conduct a two-arm parallel randomized controlled trial with an active control group. Patients will be assessed pre-intervention and after 3, 6, 9, and 12 months. The target sample size is 160 participants before randomization. The investigators will recruit patients with stage III/IV solid tumors or advanced hematological cancer and clinically significant existential distress from psycho-oncology clinics and referring oncologists at Hamburg, Düsseldorf, and Würzburg Comprehensive Cancer Centers. Outcome assessments will be conducted via diagnostic interviews and self-report questionnaires. Linear mixed models will examine outcome differences between trial arms. A confirmatory test of the group contrast at 6 months-follow-up will be conducted.
Discussion: Due to an aging population and prolonged survival, there is a growing demand to help patients deal with existential challenges. The study will contribute to knowledge about how clinicians can best help patients with advanced cancer who substantially struggle with uncertainty at the end of life.
