考虑到最近关于癌症疼痛经历种族差异的不一致发现，有必要通过多种方法澄清种族与癌症疼痛经历的关联。然而，目前只有少数研究一般癌症疼痛的经验种族差异，和少数症状群的研究，特别是有关癌症疼痛的经验种族差异。本研究的目的是对报告有相似癌症疼痛经历的癌症患者进行聚类，并确定聚类中的种族差异。这是对一项关于美国四个主要种族癌症患者癌症疼痛经历的大型互联网研究数据的二次分析。仅388例回答了癌痛、癌症症状和功能状态问题的受试者被纳入该次要分析。资料分析采用分层聚类分析和多项Logistic回归分析。采用三组解决方案：1）组1，疼痛程度低，症状轻，功能状态高; 2）组2，疼痛程度中等，症状轻，功能状态中等; 3）组3，疼痛程度高，症状轻，功能状态低。在第2组中，癌症疼痛和功能状态评分存在种族差异;亚裔美国人报告的疼痛评分低于其他种族，非裔美国人的功能状态评分高于其他种族。在第3组中，症状评分存在种族差异（p < 0.05）;非裔美国人报告的症状评分高于白人。这项研究的结果增加了一个重要的信息种族差异的症状群。这项研究表明，进一步的全国范围内的研究聚类多种族群体的癌症患者的癌症疼痛的经验。
Considering recent inconsistent findings on ethnic differences in cancer pain experience, there is a need to clarify the association of ethnicity to cancer pain experience through diverse approaches. However, there currently exist only a small number of studies on ethnic differences in cancer pain experience in general, and few symptom cluster studies specifically related to ethnic differences in cancer pain experience. The purpose of this study was to cluster cancer patients who reported similar cancer pain experience, and to determine ethnic differences in the clusters. This was a secondary analysis of the data from a larger Internet study on cancer pain experience of four major ethnic groups of cancer patients in the United States. Only 388 subjects who responded to the questions on cancer pain, cancer symptoms, and functional status were included for this secondary analysis. The data were analyzed using hierarchical cluster analysis and multinomial logistic analysis. A three-cluster solution was adopted: 1) Cluster 1 with low pain, low symptoms, and high functional status, 2) Cluster 2 with moderate pain, low symptoms, and moderate functional staus, and 3) Cluster 3 with high pain, moderate symptoms, and low functional status. In Cluster 2, there were ethnic difference in the cancer pain and funtional status scores; Asian Americans reported lower pain scores than did other ethnic groups, and African Americans had higher funtional status scores than did other ethnic groups. In Cluster 3, there were ethnic difference in the symptom scores (p < 0.05); African Americans reported higher symptom scores than did whites. The results of this study add an important piece of information on ethnic differences in symptom clusters. This study suggests further national scope studies on clustering multiethnic groups of cancer patients by cancer pain experience.
