简要总结
Previous studies have demonstrated that sniff dogs can identify cancer patients from healthy subjects through sniffing exhaled breath air or blood or serum or urine or feces. It is hypothesized that sniff dogs may be used as a tool in identifying cancer patients in the high risk population or suspected patients. Trained dogs will sniff serum from participants who are suspected to suffer from tumor by their physicians and not yet but will be diagnosed by pathological examination.The results will be compared with the outcome of the pathological examination.

结局指标
主要结局
sensitivity and specificity of the sniff dogs as a tool in diagnosing tumors
时间窗: 12 months
The results that obtained from the dogs will be compared with these of the pathological examinations. Sensitivity = the No. of patients identified by the dogs as cancers / the No. of patients suffering from cancer confirmed by pathological examination. Specificity = No. of subjects signaled by the dog as non-cancers / No. of subjects confirmed by pathological examination as non-cancer subjects.
次要结局
- behavior patterns of the sniff dogs to different diseases(12 months)
