Patients with both cancer and psychosis-to what extent do they receive specialized palliative care

BACKGROUND

Schizophrenia and advanced cancer are complex conditions that impact life expectancy. This study aimed to examine the receipt of specialized palliative care (SPC) in patients with metastatic cancer and a coexisting diagnosis of psychosis compared to patients with cancer only. Secondary objectives included analyzing differences in emergency visits and place of death in relation to receipt of SPC.

PATIENTS AND METHODS

This retrospective, observational registry study utilized health care consumption data from the Stockholm Regional Council. We included 23,056 patients aged >18 years who died between 2015 and 2021 with a diagnosis of metastatic cancer, hematologic malignancy, or malignant brain tumor in the Stockholm Gotland region. Among them, 320 patients had a concomitant diagnosis of psychosis.

RESULTS

Patients with cancer and psychosis were less likely to receive SPC compared to patients with cancer only (61% vs. 74%, p < 0.001). Additionally, they were, on average, four and a half years younger at the time of death (68.5 years vs. 73.1 years, p < 0.0001), more likely to reside in nursing homes (25% vs. 11%, p < 0.0001), and had a higher prevalence of low area-based socioeconomic status (46% vs. 32%, p < 0.0001). Receipt of SPC was associated with reduced frequency of emergency visits and a higher probability of place of death to be at home or in a care facility outside the acute hospital.

CONCLUSIONS

Patients with a coexisting diagnosis of psychosis and metastatic cancer have a lower probability of receiving SPC. Receipt of specialized palliative care was associated with reduced number of unplanned emergency visits and a lower risk for death at an acute hospital. Efforts are needed to ensure equitable provision of SPC for patients with cancer and psychosis.

CD4+ and CD8+ T cells in sentinel nodes exhibit distinct pattern of PD-1, CD69, and HLA-DR expression compared to tumor tissue in oral squamous cell carcinoma

Anticancer immunotherapies have revolutionized cancer management, yet the effect of systemic anti-programmed cell death protein 1 (PD-1) treatment is predominantly studied in tumor-infiltrating lymphocytes (TILs). Its impact on PD-1 expressing cells in tumor-draining lymph nodes (TDLNs) is not well understood and yet to be explored. Thus, further research aiming for better understanding of the PD-1 pathway not only in tumor tissue but also in TDLNs is warranted. In this study, we investigated the expression of PD-1, CD69, and HLA-DR on CD4+ and CD8+ T cells by flow cytometry analysis of peripheral blood mononuclear cells (PBMCs), TDLNs, and tumor samples from patients with oral squamous cell carcinoma (OSCC). Our data showed that both helper and cytotoxic T lymphocytes in OSCC tissue were highly activated and expressed high level of PD-1 (over 70% positivity). Lymphocytes in TDLNs and peripheral blood expressed significantly lower levels of PD-1 and other activation markers compared to TILs. Moreover, we demonstrated that a significant fraction of PD-1 negative TILs expressed high levels of human leukocyte antigen - DR isotype and CD69. In contrast, PD-1 negative cells in TDLNs and PBMCs scarcely expressed the aforementioned activation markers. Furthermore, we proved that patients with a high percentage of CD3+ PD-1+ cells in tumor-draining lymph nodes had significantly lower disease-free and overall survival rates (log-rank test P = .0272 and P = .0276, respectively). Taken together, we proved that flow cytometry of lymph nodes in OSCC is feasible and may be used to investigate whether PD-1 levels in TDLNs correspond with survival and potentially with response to anti-PD-1 therapy. Such knowledge may ultimately help guide anti-PD-1 treatment.
