BackgroundT-cell immunoglobulin and ITIM domain (TIGIT) is identified as a novel checkpoint receptor that can facilitate immune escape via mediating T-cell exhaustion in tumors. However, the clinical significance and immune contexture correlation of intratumoral TIGIT+ CD8+ T-cells remain to be further explored in muscle-invasive bladder cancer (MIBC).Methods259 patients with MIBC from two clinical centers (Zhongshan Hospital, n=141; Shanghai Cancer Center, n=118) were analyzed to evaluate the prognostic value and immune contexture association of TIGIT+ CD8+ T-cells through immunohistochemistry. Fresh tumor tissue samples from 26 patients with MIBC were examined to discover the phenotype of this CD8 subpopulation by flow cytometry.ResultsHigh infiltration of intratumoral TIGIT+ CD8+ T-cells predicted poor overall survival (OS) and recurrence-free survival (RFS) in MIBC. For patients with stage II MIBC with low infiltration of TIGIT+ CD8+ cells, adjuvant chemotherapy (ACT) could significantly prolong their OS and RFS. Intratumoral TIGIT+ CD8+ T-cell abundance was correlated with impaired CD8+ T-cell cytotoxicity and exhibited production of immunosuppressive cytokine IL-10. Further analysis of tumor-infiltrating immune cell landscape revealed TIGIT+ CD8+ T-cells were associated with suppressive immune contexture, including Th2 cells, regulatory T-cells, mast cells and neutrophils.ConclusionIntratumoral TIGIT+ CD8+ T-cell abundance could serve as an independent prognosticator for clinical outcome and a predictive biomarker for inferior ACT responsiveness. Intratumoral TIGIT+ CD8+ T-cell abundance correlated with dampened CD8+ T-cell antitumor immunity and immunosuppressive contexture abundance, highlighting a tumor-promoting role of TIGIT+ CD8+ T-cells.

Purpose. To compare the expression level of apelin in muscle-invasive bladder cancer and matched paracarcinoma tissues and investigate the relationship between apelin and clinical prognosis in the patients. Methods. To assess apelin expression by using immunohistochemical method compared with bladder tumors and matched paracarcinoma tissues. Subsequently, the correlation of apelin expression with the clinicopathological features of bladder cancer patients was analyzed. Kaplan-Meier survival curves method was used to analyze apelin prognostic significance for muscle-invasive bladder cancer patients (including 404 muscle-invasive bladder cancer patients and 28 normal bladder tissues, in TCGA dataset). Results. Apelin protein level was overexpressed in bladder tumor tissues compared with paracarcinoma tissues. Furthermore, high apelin expression was associated with high tumor stage (P<0.05), distant metastasis (P<0.05), and vascular invasion (P<0.05). Kaplan-Meier curve analyses showed that the overexpression of apelin was a potential predictor of overall survival and disease-free survival. Conclusion. Apelin was upregulated in bladder tumor tissues compared with matched adjacent noncancer tissues, especially in the high tumor stage, distant metastasis, and vascular invasion. What is more, high expression of apelin in muscle-invasive bladder cancer indicates the poor prognosis. These data suggested that apelin might be a therapeutic potential biomarker in muscle-invasive bladder cancer patients.

Abstract Introduction Radical cystectomy remains the standard of care for muscle-invasive bladder cancer and high-risk non-muscle-invasive bladder cancer. Postoperative ostomy education is common, but patients struggle to maintain self-management practices. A preoperative ostomy education program was developed to meet this need, and we conducted a qualitative study with participating patient-caregiver dyads to evaluate the educational and psychosocial impacts of the program and examine alignment with program objectives. Materials and methods A qualitative descriptive study was conducted utilizing a thematic analysis approach. Sixteen patients, eighteen caregivers, and three program educators completed semi-structured interviews from 3 to 18 months post the program. Interviews were audio-recorded and transcribed. Thirteen end-of-course surveys from the initial educational program cohort were transcribed, coded, analyzed; this data was triangulated with patient, caregiver, and educator interviews. Results Analysis uncovered three themes: (1) Patient and caregiver motivation to attend the program, (2) attitudes toward this life-changing event, and (3) education. For theme 1, patients and caregivers cited lack of knowledge, fear, and concern about ostomy surgery and care as motivation. For theme 2, there were a variety of attitudes toward the ostomy, ranging from avoidance to acceptance, and a similar breadth of attitudes toward caregiving, with some patients and caregivers describing ongoing dependence and other patients seeking complete independence. For theme 3, the interactive curriculum was determined to be effective, and the patient advocate was cited as the most memorable program component. Conclusions A formal preoperative ostomy education program employing an interactive educational approach and featuring a patient advocate can prepare bladder cancer patients and caregivers for ostomy self-management and post-ostomy life.
