Breast Cancer Detection from a Urine Sample by Dog Sniffing
Research Square (Research Square)(2020)
摘要
Background: Breast cancer is a leading cause of cancer death worldwide. Several studies have demonstrated that dog can sniff and detect cancer in the breath or urine sample of a patient. Objective: The aim of this study is to assess whether the trained dog can detect breast cancer from urine samples.Methods: A nine-year-old female Labrador Retriever was trained to identify cancer from urine samples of breast cancer patients. Urine samples from patients histologically diagnosed with primary breast cancer, those with non-breast malignant diseases, and healthy volunteers were obtained, and a double-blind test was performed. Results: 40 patients with breast cancer, 142 patients with non-breast malignant diseases, and 18 healthy volunteers were enrolled, and their urine samples were collected. In 40 times out of 40 runs of a double-blind test, the trained dog could correctly identify urine samples of breast cancer patients. Sensitivity and specificity of this breast cancer detection method using dog sniffing were both 100%.Conclusions: The trained dog in this study could accurately detect breast cancer from urine samples of breast cancer patients. These results indicate the feasibility of a method to detect breast cancer from urine samples using dog sniffing in the diagnosis of breast cancer.
