TOMSK, May 18 – RIA
Tomsk. Scientists of Tomsk State University (TSU) developed a technique which will allow on the basis of the
analysis of the exhaled air to define, which patient has bronchopulmonary
diseases, including lung cancer and who is healthy, the press service of the
university reports.
It is noted that scientists developed a method which
will allow to analyze composition of the air exhaled by the person and to
reveal markers of concrete diseases. For carrying out the analysis in TSU the
laser gas analyzer was used - the device can define more markers, than its
analogs. Clinical tests of a method were carried out in 2015, now data
collection continues.
"Clinical trials confirmed ability of a
technique with probability higher than 90% to distinguish patients with cancer
of lungs from patients with a chronic obstructive pulmonary disease or healthy
examinees and with 70% probability to reveal healthy ones. Thus, the method has
shown 80% accuracy", – is said in the message.

It is added that scientists have presented
intermediate results of the work in February, 2016 at the Photonics West
conference in San Francisco (USA). Researches are part of joint project of TSU
and Siberian State Medical University within the federal target program. It is
planned to create a more simple and cheap device for mass inspections of the
population.
"We plan that for the end user it will be the
simple device with a disposable mouthpiece in which the patient has to make an
exhalation, and after the analysis the device will define, whether the person
is sick or not", – the press service quotes the project manager, TSU
deputy pro-rector on scientific work Yury Kistenev.
It is reported also that the sum of the state
subsidy allocated for the project of Tomsk scientists makes 14,5 million
rubles. It is supposed that scientists will finish development of a technique
until the end of 2016, and then on its basis the hardware and software system
will be created.
