Papillary craniopharyngiomas (PCPs) are biologically benign but clinically aggressive lesions hence affect the quality of life. The expression of inflammatory mediators and regulation of the immune microenvironment in PCPs have not been investigated much. In this study, for the first time, we assessed the immune cell infiltration and immune cell signatures in PCPs by analyzing the bulk-RNA sequencing data and immunohistochemical staining. Additionally, we performed qRT-PCR analysis to detect inflammatory mediators interleukin-1a (IL1A) and interleukin-6 (IL6) in different aggressive groups and then developed the IL1A and IL6 prediction models for defining the degree of hypothalamic invasion. Lastly, we defined differentially expressed genes related to invasiveness and implemented enrichment analysis to them. Our results indicated that PCPs are in a state of high immune infiltration but low action with abundant inflammatory cells. High infiltration of neutrophils may lead a low active immune microenvironment. Furthermore, the high expression level of IL1A and IL6 was positively correlated with the invasion of PCP tumors in the hypothalamus. These findings provide new pathological insights into the underlying mechanism of the immune microenvironment in PCP tumors. Moreover, IL1A and IL6 might serve as potential therapeutic targets for PCP tumors, especially to prevent their invasion into the hypothalamus. [ABSTRACT FROM AUTHOR]

Objective: To analyze the risk factors relative to postoperative psychiatric disorders in adult patients with craniopharyngioma.Methods: A retrospective case-control study design was used in this study. The Neuropsychiatric Inventory–Questionnaire (NPI-Q) assessment tool was used to assess psychiatric disorders in postoperative patients with craniopharyngioma at Beijing Tiantan Hospital from January 2018 to December 2020. The relationship between the psychiatric disorders and basic demographic data as well as several risk factors, such as the tumor characteristics (tumor location, tumor size, pathological finding of the tumor, etc.) and treatment-related factors (the extent of the resection), were analyzed.Results: A total of 173 patients were included in this study. The prevalence of psychiatric disorders was 14.5% among adult craniopharyngioma patients. Irritability represented the most common type of psychological symptom (64%, n = 16), followed by agitation (36%, n = 9), and delusions (28%, n = 7). The risk factors relative to postoperative psychiatric disorders that were identified were a tumor volume larger than 7 cm3 (HR = 3.292, P = 0.042), tumor location (P = 0.003), hypothalamic invasion (HR = 9.766, P = 0.036), and gross-total resection (HR = 0.085, P = 0.042).Conclusion: Neurocognitive assessment and intervention before and after surgery are important in patients with larger tumors, invading the third ventricle, and tumors with hypothalamic invasion. Prediction of these risk factors is essential for the treatment.
