The basic details of randomised clinical studies in cancer treatment under way in the United Kingdom were ascertained in a postal survey. The cancers of major interest were those of lung, breast, colon and rectum, and lymphomas and leukaemias. In general, only a small proportion of cancer patients are entered into clinical studies; and most of the individual studies aim for a small number of patients, with patient entry over a long period.
通过一项邮寄调查确定了英国正在进行的癌症治疗随机临床研究的基本细节。主要关注的癌症类型为肺癌、乳腺癌、结肠癌、直肠癌、淋巴瘤和白血病。一般来说，只有一小部分癌症患者会参与临床研究；而且大多数单项研究的目标患者数量较少，患者入组时间较长。
