00:00This project is a research project to educate dogs to detect cancer in transplantation,
00:24that is, through the skin.
00:27It's beautiful, isn't it?
00:29The project is part of a research project to educate dogs to detect cancer in transplantation,
00:33that is, through the skin.
00:52Each sample is obtained by a person, a woman,
00:57who puts it on her chest and collects the sweat,
01:01because she keeps it all night in the throat support.
01:04So when we know that the person has nothing,
01:07we get a negative sample,
01:09and if, unfortunately, there are people who have a tumor,
01:13it allows us to obtain positive samples,
01:15so with red label.
01:23It's impressive.
01:25It takes a lot of motivation to get to this training.
01:28At first, we make him look for his toy,
01:30it's a reward.
01:32For Milou, it's the ball,
01:34for Nougaro, it's the rubber condom.
01:37At first, it's a search for the object,
01:39and then, when he knows how to look for his object,
01:43we put next to the object the molecule we want to look for,
01:46among other things, a compress with the smell of the tumor.
01:50And the dog makes the association,
01:52each time he has his ball, there is this smell next to it,
01:55and he ends up memorizing it,
01:57and then we remove the ball,
01:59and when he finds this smell of the tumor,
02:01we give him the reward.
02:03Then comes the work of what we call the whites,
02:05that is, to teach him that if there is no positive in the line,
02:09he must go and sit at the end,
02:11and sit on a carpet or a board,
02:14to say there is nothing, and make a mark too.
02:17And he is rewarded right away.
02:22The dog is given the ball,
02:24and Nougaro is given the ball.
02:38Here we are on something very subtle,
02:41which is inside the body, it's a small tumor,
02:44so there is no crowd of volatile compounds,
02:47and it can be mixed with a lot of other things.
02:50The exercise asked to the dog is really periodic and delicate,
02:53and that's the whole point of clinical study,
02:55is that the dogs are able to repeat it over a distance,
02:59to really be a diagnostic tool.
03:03The goal is not to replace imaging,
03:05namely mammography, echography,
03:07but rather to situate yourself in pre-test,
03:09that is, with an invasive method,
03:12and easy to say, cancer, no cancer.
03:16If there is no cancer, we will not do the exam,
03:18if there is cancer, of course, we have to do the mammography,
03:21to see where the tumor is, how it presents itself,
03:24if there is a biopsy, where we have to do the biopsy.
03:28So it would be a pre-test,
03:31which can be interesting here in France,
03:33which can also be particularly interesting in countries
03:36where there are not enough devices
03:38to be able to detect all populations.
