无家可归的人群（PEH）相比非无家可归人群，患有不良健康结果和过早死亡的患病率更高。其中包括更高的癌症和癌症特定发病率和死亡率负担，这可能是由于无法获得初级和次级预防和社区卫生服务的重要阻碍所导致。本研究旨在更好地理解欧洲四个国家的PEH对健康需求和预防癌症护理的障碍，以及为这一人群开发干预措施所需的考虑因素。在这项探索性定性研究中，我们进行了69次半结构化访谈，涵盖了奥地利、希腊、西班牙和英国的样本，包括15名从事无家可归人员支持服务的专业人士、19名卫生专业人士和35名PEH。访谈时间为2021年8月1日至10月31日，数据采用课题法进行了归纳和迭代分析。研究结果被归纳为两个主题：（1）对癌症预防和治疗的经历和理解；（2）方案干预的考虑因素。尽管在所有环境中，癌症对PEH来说是一个重要的担忧，但他们对癌症症状和预防的认识通常很少。有关PEH的癌症预防具体项目几乎不存在。一些环境中的卫生专业人士表示，PEH经常在早期阶段未能被及时发现癌症，而是在症状加重的严重阶段被诊断出来。总的来说，我们的研究结果表明，PEH的健康需求和面临的障碍在欧洲背景下存在许多共同点。本研究得到了欧洲联盟的Horizon 2020研究与创新项目下GA 965351的资助。© 2023 The Authors.

People experiencing homelessness (PEH) have a higher prevalence of adverse health outcomes and premature mortality compared to the non-homeless population. These include a higher burden of cancer and cancer-specific morbidity and mortality-outcomes that may be a consequence of significant barriers to accessing primary and secondary prevention and community health services. This study aimed to better comprehend the health needs and barriers to accessing preventive cancer care for PEH across four European countries as well as necessary considerations for developing interventions around cancer prevention for this population.In this exploratory qualitative study, 69 semi-structured interviews were conducted across Austria, Greece, Spain, and the UK, with a sample comprising 15 professionals working in homelessness support services, 19 health professionals, and 35 PEH. Interviews took place between August 1 and October 31, 2021, and data were analysed inductively and iteratively following a thematic approach.Findings were organised into two overarching themes: (1) Experiences and understanding of cancer prevention and treatment and (2) Considerations for program interventions. While cancer was a significant worry among PEH across all settings, they generally had minimal knowledge and understanding of cancer symptoms and prevention. Specific programs for cancer prevention for PEH were described as almost non-existent. Health professionals in some settings indicated that cancer in PEH was often missed in the early stages and instead diagnosed when the severity of symptoms intensified.Overall, our findings indicate many commonalities in the health needs of PEH and the barriers they face when they seek access to cancer-specific healthcare services in the European context.This study received funding from the European Union's Horizon 2020 Research and Innovation Programme under GA 965351.© 2023 The Authors.
