简要总结
Some groups reported that sniffer dogs can be applied to detect lung cancer in the exhaled breath of patients. Therefore, breath samples (BS) of patients are collected. Five sniffer dogs are trained to distinguish between the BS of patients with lung cancer and healthy individuals (controls). In a prospective, randomized blinded study the dog's ability to differentiate between BS of i) patients with lung cancer, ii) patients with inflammatory airway disease, but no evidence of cancer and iii) healthy individuals is tested.
详细描述
All breath samples (BS) are collected in patients on the basis of radiologic findings before any intervention (bronchoscopy, biopsy or surgery) has been performed. The allocation to study groups is made following diagnostic work up and surgery.
Three study groups are defined using the following inclusion and exclusion criteria:
- lung cancer: male & female, age 18-80, competent, confirmed lung cancer in diagnostic work up and surgery, no history or present other tumor disease
- healthy individual: male & female, age 18-80, competent, no history or present other tumor disease including lung cancer, no pathological lung function tests
- chronic obstructive lung disease: male & female, age 18-80, competent, no history or present other tumor disease including lung cancer, pathological lung function tests
For each patient, i) history, ii) present medication, iii) lung function tests are documented. For the lung cancer patients, the tumor stage following surgery is documented.
Five sniffer dogs are trained using BS of lung cancer patients and healthy individuals. After completion of the training the ability of the dogs to differentiate between the groups is tested:

结局指标
主要结局
presence of an heretofore unknown substrate in the exhalation sample of a patient with confirmed lung cancer
时间窗: baseline
number of individuals in the study cohort with confirmed lung cancer whose exhalation sample is correctly identified by sniffer dogs to contain an heretofore unknown substrate that is associated with lung cancer
次要结局
- absence of an heretofore unknown substrate that is associated with lung cancer in patients with lung disease but excluded lung cancer(baseline)
