Cervical cancer screening is expected to measure directly after 7 seconds of rapid measurement of exhalation

Medical Network October 25th reporter learned from the Chinese Academy of Sciences Hefei Institute of Material Science on the 23rd, the Institute of Medical Physics has made progress in the rapid screening of cervical cancer research. Using a self-developed exhaled mass spectrometer, researchers can directly measure the exhalation of a subject in as little as 7 seconds.

This research was published recently in "Analytical and Bioanalytical Chemistry."

Cervical cancer is a serious threat to women's health, a common malignant tumor, the world's new cases each year half a million, of which China accounted for about one-third of patients, cervical cancer is the third-largest Chinese young female high incidence of cancer.

Commonly used cervical cancer screening methods mainly include cytological examination (Pap examination), human papillomavirus examination (HPV examination), all require instrument invasion, and cell or virus detection takes a certain time.

Because of its characteristics of safety, non-invasiveness, simplicity, and high acceptance, breath detection has always been a research hotspot in the field of diagnosis.

Researchers at the Hefei Institute of Material Science of the Chinese Academy of Sciences have developed a real-time online detection of exhaled mass spectrometer, which can directly measure the exhalation of a subject in just 7 seconds. Through the breath test of 13 cervical cancer patients and 34 healthy people, it was found that the four exhaled mass spectrometry characteristic ions that distinguish cervical cancer were used to determine the true positive rate and true negative rate of cervical cancer, which were 92.3% and 88.2, respectively. %.
