Psychiatric assessment for patients who decline cancer treatment: perspectives from medical residents

PURPOSE

Among patients with cancer, a comorbid mental disorder is associated with higher mortality. This could be partially attributed to reduced access to oncological care, sometimes due to treatment refusal. Recommendations were issued in 2018 by the French and Francophone Society of Psycho-Oncology concerning the management of oncological treatment refusal. This study aimed to examine oncology residents' view on psychiatric assessment in this context.

METHODS

In February 2021, we conducted a descriptive, observational, cross-sectional pilot study among French residents involved in oncology regarding their management of cancer treatment refusal and the importance they assign to psychiatric assessment, using an online questionnaire with 12 multiple-choice questions.

RESULTS

Among 87 respondents, only 35.6% systematically explore the history of mental disorders when facing cancer treatment refusal. Even in cases with a known history of mental disorders, only 42.5% systematically refer the patient to a psychiatrist. 96.5% of them were unaware of the 2018 recommendations.

CONCLUSION

The importance given to psychiatric assessment in cases of oncological treatment refusal remains insufficient. Qualitative studies are needed to understand the underlying reasons for this refusal. The development of psychiatric consultation-liaison interventions in oncology centers is necessary to improve the management of these cases and provide appropriate training.

Uveal Melanoma: Refusal of Treatment

Purpose

This study aimed to explore factors for refusing treatment in patients diagnosed with uveal melanoma and their subsequent clinical course.

Methods

This study included patients with uveal melanoma who refused standard of care treatment. Patient-reported reasons and pre-existing mental health diagnoses were assessed. The sociodemographic profile was compared with the controls. Ocular survival, metastasis-free survival (MFS), and overall survival (OS) were calculated.

Results

Nine patients with uveal melanoma declined ocular treatment (plaque brachytherapy, n = 7 [78%]; enucleation, n = 2 [22%]). The choroidal melanomas were small (n = 1 [11%]), medium (n = 5 [56%]), and large (n = 3 [33%]) in size (COMS criteria). The sociodemographic profile of the study patients was not different from those that accepted treatment. One patient (11%) had pre-existing mental health diagnosis. Five patients (56%) eventually accepted treatment following an average delay of 19 months (range: 4-55 months) due to neovascular glaucoma or severe vision loss. MFS could not be ascertained, and OS was 67% (6/9) at 4.2 years of follow-up (mean).

Conclusions

Refusal of initial recommended treatment is associated with poor ocular survival. The small sample size did not allow for an evaluation of the impact on survival.

Biomarkers of immunotherapy in non-small cell lung cancer

Immunotherapy has markedly improved the survival rate of patients with non-small cell lung cancer (NSCLC) and has introduced a new era in lung cancer treatment. However, not all patients with lung cancer benefit from checkpoint blockade, and some suffer from notable immunotoxicities. Thus, it is crucial to identify potential biomarkers suitable for screening the population that may benefit from immunotherapy. Based on the current clinical trials, the aim of the present study was to review the biomarkers for immune checkpoint inhibition, as well as other effective, invalid and hyperprogression markers that may have the potential to better predict responders to immunotherapy among patients with NSCLC. All these biomarkers may be incorporated into the predictive utility of bio-score systems and decision-making algorithms, to better guide the application of immunotherapy in the clinical setting.
