中文摘要
背景：预防性医疗服务获取有限的社区仍面临更高的癌症晚期诊断和死亡负担。尽管全国癌症死亡率有所下降，但持续存在的障碍——包括筛查延迟、导航支持有限以及对医疗机构的信任度低——仍减缓着进展。在这些环境中取得可持续的进步，需要能够增强本地能力、扩展筛查途径并使居民成为可信的癌症信息传递者的模式。
方法：南加州大学Norris综合癌症中心社区外展与参与办公室（COE）在其覆盖区域（洛杉矶县和橙县北部）实施双重策略：（1）设立于可信场所（社区中心、YMCA分支机构和The Men's Cancer Network Inc.）的癌症健康枢纽（CWHs），以及（2）面向社区成员开放的循证癌症大使培训。经过培训的双语/双文化社区卫生工作者提供现场教育、保险登记导航、癌症筛查以及诊断随访或临床试验入组的转诊。大使培训为两小时的课程，涵盖流行病学、风险降低、早期症状、治疗基础知识、幸存者关怀和有效沟通。标准化的前/后测调查测量知识、自我效能和分享信息的意愿。
结果：2025年，19个CWHs覆盖了714名社区成员，提供了文化和语言上契合的癌症教育和资源。其中，29名需要随访（筛查、诊断或治疗导航）的个体被成功对接到USC Norris COE患者导航员。26名参与者于2025年在洛杉矶完成了癌症大使培训。综合知识评分从65.0%（前测）提高到79.3%（后测），其中在胰腺癌和前列腺癌意识方面获得的提升最大。96%的受训者报告有意向在其社交网络内传播所学信息。在一次以前列腺癌为重点的培训中，9名年龄≥40岁的男性接受了现场免费的PSA筛查。
结论：整合的癌症健康枢纽和癌症大使培训模式展现出高接受度、显著的知识提升以及向社区行动的快速转化，包括直接的筛查参与和同伴间教育。通过培训和赋能居民成为可信的信息传递者，并在可信空间内共址提供服务，这一可扩展、基于资产的方法有效弥合了在预防、早期检测和临床试验获取方面的差距。这些发现凸显了持续、双向的社区-学术合作伙伴关系在拆除结构性障碍以及加速缩小服务不足人群中癌症差异方面的价值。

Background: Communities with limited access to preventive care continue to face higher burdens of late-stage cancer diagnoses and mortality. Persistent barriers including delayed screening, limited navigation support, and low trust in medical institutions slow progress despite national declines in cancer deaths. Sustainable advances in these settings require models that strengthen local capacity, expand screening pathways, and equip residents as credible messengers of cancer information.
Methods: The USC Norris Comprehensive Cancer Center, Office of Community Outreach and Engagement (COE) implements a dual strategy across its catchment area of Los Angeles County and northern Orange County: (1) Cancer Wellness Hubs (CWHs) situated in trusted venues (community centers, YMCA branches, and The Men's Cancer Network Inc.) and (2) Evidence-informed Cancer Ambassador Trainings open to community members. Trained bilingual/bicultural community health workers provide on-site education, navigation to insurance enrollment, cancer screening, and referrals for diagnostic follow-up or clinical-trial enrollment. Ambassador Trainings are two-hour sessions covering epidemiology, risk reduction, early symptoms, treatment basics, survivorship, and effective communication. Standardized pre/post surveys measure knowledge, self-efficacy, and intent to share information.
Results: In 2025, 19 CWHs engaged 714 community members, delivering culturally and linguistically congruent cancer education and resources. Of these, 29 individuals requiring follow-up (screening, diagnostic, or treatment navigation) were successfully connected to USC Norris COE patient navigators.
Twenty-six participants completed Cancer Ambassador Trainings in Los Angeles in 2025. Aggregate knowledge scores increased from 65.0% (pre) to 79.3% (post), with the largest gains observed in pancreatic and prostate cancer awareness. Ninety-six percent of trainees reported intent to disseminate learned information within their social networks. At one prostate-cancer-focused training, nine men aged ≥40 received on-site free PSA screening.
Conclusions: The integrated Cancer Wellness Hub and Cancer Ambassador Training model demonstrates high acceptability, significant knowledge gains, and rapid translation into community action, including direct screening uptake and peer-to-peer education. By training and empowering residents as credible messengers and co-locating services in trusted spaces, this scalable, asset-based approach effectively bridges gaps in prevention, early detection, and clinical-trial access. These findings underscore the value of sustained, bidirectional community-academic partnerships in dismantling structural barriers and accelerating the reduction of cancer differences in underserved populations.
