High Apelin Level Indicates a Poor Prognostic Factor in Muscle-Invasive Bladder Cancer

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 In patients with various cancers, modified Glasgow prognostic score (mGPS) before treatment has predicted prognoses after antitumor therapy. This study aimed to assess whether pretreatment mGPS also has predictive value in patients with muscle-invasive bladder cancer (MIBC) after radiotherapy. A retrospective review accumulated 98 consecutive MIBC patients treated with definitive 3D-conformal radiotherapy from January 2011 to December 2016 in a single center. It included cT2-4bN0-3M0 patients with a median age of 79 years (range: 49 to 95 years). Radiotherapy was delivered at 60–66 Gy for bladder cancer. Patients were categorized in terms of their pretreatment serum albumin and C-reactive protein (CRP) values as mGPS_0, mGPS_1, and mGPS_2. Among them, cumulative overall survival (OS) rates were compared by Kaplan–Meier plots with log-rank tests. The number of patients with mGPS_0, mGPS_1, and mGPS_2 were 40, 40, and 18, respectively. The median follow-up time for all patients was 19 months (range: 2–73 months). The 2-year OS rate for all patients was 75.7%. The 2-year OS rates for mGPS_0, mGPS_1, and mGPS_2 were 85.1%, 71.3%, and 60.9%, respectively. Kaplan–Meier curves revealed a significantly higher cumulative OS rate for mGPS_0 compared with mGPS_1 and mGPS_2 (P = 0.003). Using multivariate Cox regression analysis, mGPS_0 and good performance status were associated with favorable OS rates, of which mGPS_0 was more significant (Hazard ratio 2.74, 95% CI 1.30–5.57, P = 0.008). Modified Glasgow prognostic score may be a novel biomarker that can predict survival in patients with MIBC after radiotherapy.

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.
