Cancer patients' return-to-work rates in Japan and their methodological quality have been little reported. We conducted a systematic review to explore the recent return-to-work rates and to assess the methodological quality of the existing literature. We selected 13 papers (2 in English and 11 in Japanese) published between 2005 and 2017. The return-to-work rates ranged from 53.8% to 95.2%. Of the selected papers, 12 papers employed a cross-sectional design, possessing high risk of selection bias due to participant selection. A total of 8 papers did not fully report the subjects' sex, age, employment status at cancer diagnosis, cancer site, stage, and treatment, suggesting high risk of selection bias due to confounding variables. High or unclear risk of attrition bias due to incomplete outcome data was detected in 12 papers in which data on return to work were not collected from all participants. High risk of reporting bias due to selective outcome reporting was pointed out in 6 studies in which the subjects' employment status at return to work or the duration between cancer diagnosis and assessment of return to work was unclear. Future studies must reduce the risk of selection, attrition, and reporting biases for specifying accurate return-to-work rates.
日本癌症患者的复工率及其方法学质量鲜有报道。我们进行了一项系统评价，旨在探索近期的复工率，并评估现有文献的方法学质量。我们选取了 2005 年至 2017 年间发表的 13 篇论文（2 篇英文，11 篇日文）。复工率范围为 53.8%至 95.2%。在所选取的论文中，有 12 篇采用了横断面设计，由于参与者的选择，存在选择偏倚的高风险。共有 8 篇论文未充分报告研究对象的性别、年龄、癌症诊断时的就业状况、癌症部位、分期和治疗情况，提示由于混杂因素存在选择偏倚的高风险。有 12 篇论文由于未从所有参与者中收集有关复工的数据，存在着因结局数据不完整而导致的离职偏倚的高风险或不明确风险。有 6 项研究由于选择性报告结局，指出存在因报告偏倚而导致的高风险，这些研究中复工时的就业状况或癌症诊断和评估复工之间的时间间隔不明确。未来的研究必须降低选择、离职和报告偏倚的风险，以明确准确的复工率。
