Nevertheless, among the patients with high mutation burdens, some still remained refractory to immunotherapy. The B7 family molecules have long been perceived as vital determinant of immune response and may define dominant molecular subsets associated with immunotherapeutic response. Simultaneously, our previous study (Eur J Cancer. 2022,171:133-142) unveiled the potential of B7-H4 as a candidate biomarker to refine the predictive capability of tumor mutation burden (TMB) in immunotherapeutic efficacy based on its significant correlation with TMB in MIBC. We hypothesized that the integration of B7 family molecules with TMB could better identify patients with better response to checkpoint blockade.\n\nIn this retrospective study, a total of 1,084 UC patients from 5 independent cohorts were enrolled. We established the B7 Family Score (BFS) by the expression patterns of three B7 family members: PD-L1 (CD274), B7-H3 (CD276) and B7-H4 (VTCN1) based on protein and transcriptomic level respectively. We further investigated the correlation of BFS with genomic features and therapeutic response in UC. In addition, we integrated the BFS with tumor mutation burden (TMB) to better stratify the clinical benefit from PD-L1 blockade and platinum-based chemotherapy.', 'detailedDescription': 'On the basis of established findings in the prognostic and functional properties of the three B7 family members, i.e., PD-L1, B7-H3, and B7-H4, we employed the IMVigor210 cohort as the discovery cohort to establish the concept of B7 Family Score (BFS). To maximize the prognostic value of the system, we introduced the R package survMisc (0.5.5) in the IMvigor210 cohort to determine the best cut-off value of mRNA expression level of the B7 family members (i.e. CD274, CD276, and VTCN1) by calculating the minimum log-rank P value accordingly.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Among the 215 patients originally diagnosed with bladder cancer who underwent radical cystectomy at Zhongshan Hospital of Fudan University from 2002 to 2014, eighty-seven patients were excluded: 60 patients without muscle-invasive bladder cancer (MIBC), 13 patients with non-urothelial carcinoma, and 36 specimens with dots lost on the tissue microarray (TMA) during the immunohistochemistry (IHC) assay. Therefore, 106 patients are enrolled in the ZSHS cohort, 51 of whom received adjuvant cisplatin-based chemotherapy which lasted at least one therapeutic cycle.
