Patients with either leukemia or lymphoma were asked if they had close personal associations with other patients before the onset of disease. Iinitial interviews indicated that several patients could be interlinked into social clusters. Tumour-registry records were used to contact each patient (or a surviving relative) diagnosed during the years 1964-73 in three areas of West Virginia. Close personal associations, antedating the onset of disease in 1 or both individuals of each linkage pair, were detected in 14 of 23 (61%), 14 of 22 (68%), and 6 of 8 (75%) patients from these three areas during this ten-year period. In addition, among 28 randomly selected patients with Hodgkin's disease from various parts of the United States, 10 (36%) had direct or indirect close personal associations with 17 other patients with leukemia or lymphoma. Patients with leukemia or lymphoma frequently are interlinked by prior close personal associations to other patients with these diseases.
患有白血病或淋巴瘤的患者被问及在疾病发作前是否与其他患者有密切的个人交往。初步访谈表明，有几名患者可能相互关联形成社会群体。利用肿瘤登记记录联系了西弗吉尼亚州三个地区在1964年至1973年期间确诊的每位患者（或在世亲属）。在这十年期间，来自这三个地区的23名患者中有14名（61%）、22名患者中有14名（68%）以及8名患者中有6名（75%）的每个关联对中的1人或两人在疾病发作前就有密切的个人交往。此外，在美国各地随机挑选的28名霍奇金病患者中，有10名（36%）与另外17名白血病或淋巴瘤患者有直接或间接的密切个人交往。白血病或淋巴瘤患者常常通过先前与其他患有这些疾病的患者的密切个人交往而相互关联。
