A survey was carried out in 2 country areas of New South Wales with the aim of defining contacts among patients with lymphoma, leukemia and myeloma, and of determining whether these were more numerous than among matched controls from the same localities. Cases were identified from records of the N.S.W. Central Cancer Registry and of local doctors and hospitals. 184 cases were found, corresponding to the expected number, and 145 patients, as well as the same number of controls, were interviewed. Of the 290 patients and controls surveyed 111 (38.3%) had had one or more contacts with other patients or controls (37.9% of patients and 38.6% of controls). There were 24 case-case pairs involving contacts among 33 individual patients, 23 control-control pairs involving 36 individuals, and 38 case-control pairs involving 66 individuals. A statistical analysis using a weighting system showed that numbers, closeness and duration of contacts among patients and patients did not differ significantly from those expected. These results thus provide no evidence in favor of the hypothesis that the diseases were transmitted from patient to patient in the survey areas.
在新南威尔士州的两个乡村地区进行了一项调查，目的是确定淋巴瘤、白血病和骨髓瘤患者之间的接触情况，并确定这些接触是否比来自同一地区的匹配对照组更为频繁。病例是从新南威尔士州中央癌症登记处以及当地医生和医院的记录中识别出来的。共发现184例病例，与预期数量相符，并对145名患者以及相同数量的对照组进行了访谈。在接受调查的290名患者和对照组中，111人（38.3%）与其他患者或对照组有过一次或多次接触（患者为37.9%，对照组为38.6%）。有24对病例-病例接触，涉及33名个体患者；23对对照-对照接触，涉及36名个体；38对病例-对照接触，涉及66名个体。使用加权系统进行的统计分析表明，患者与患者之间接触的数量、密切程度和持续时间与预期相比没有显著差异。因此，这些结果没有提供证据支持疾病在调查地区从患者传播给患者的假设。
