癌症患者普遍出现自杀念头（SI）和抑郁症状。痛苦量表（DT）是一个有效的工具，用于筛查这类群体中的抑郁和焦虑。我们调查了DT对预测SI的价值，以及研究人群中SI的患病率和相关的风险因素。这个横断面研究共纳入162名癌症患者。收集有关社会人口学和临床特征、医院焦虑抑郁量表、DT分数和过去一个月的SI的信息。进行受试者工作特征（ROC）分析，以找到预测SI风险的准确性和最优截断分数。使用中位独立性检验获得DT分数之间的差异的显著性。通过奥斯比比率分析风险的可能性。DT对于预测癌症患者的SI具有良好的整体准确性（ROC曲线下面积=0.797）。DT具有0.929的敏感性和0.522的特异性，截断分数为≥4。患有SI的患者的DT分数显著高于未患有SI的患者（7 [5,8] v 3 [1,6]；P < .001）。SI的1个月患病率为17.3%。抑郁、焦虑和心理困扰是SI的预测因素。SI在癌症患者中是一个全球性问题。DT分数可能是一个快速预测工具，用于识别癌症患者中的SI。高DT分数以及存在心理社交问题的患者需要定期筛查SI，这可能有助于预防自杀风险。

Suicidal ideation (SI) and depressive symptoms are common in patients with cancer. A Distress Thermometer (DT) is an effective tool to screen depression and anxiety in such cohorts. We investigated the value of the DT for predicting SI and the prevalence and associated risk factors of SI in the study population.This cross-sectional study enrolled a total of 162 heterogeneous patients with cancer. Information regarding sociodemographic and clinical characteristics, the Hospital Anxiety and Depression Scale, DT score, and the past month SI were collected. Receiver operating characteristic (ROC) analysis was performed to find accuracy and the optimal cutoff score for predicting risk of SI. The significance of difference between DT scores was obtained using the median independence test. Likelihood of risk was analyzed through odds ratio.DT possesses good overall accuracy (area under the ROC curve = 0.797) for predicting SI in patients with cancer. The DT had a sensitivity of 0.929 and a specificity of 0.522 with a cutoff score of ≥4. The patients with SI had significantly higher DT scores than the patients without SI (7 [5,8] v 3 [1,6]; P < .001). The 1-month prevalence of SI was 17.3%. Depression, anxiety, and psychological distress were the predictive factors of SI.SI is a global issue in patients with cancer. The DT scores may be a rapid predicting tool for identifying SI in patients with cancer. Higher DT scores and patients with psychosocial problems need to be routinely screened for SI, which may help to prevent suicidal risk.
