The aim of this project is to develop a novel concept for gastric cancer early detection. Gastric cancer is responsible for approximately 0.8 million deaths every year and it is second to lung cancer in term of number of death. Similarly to most cancers, if diagnosis is made late in the development of the disease, the chances of recovery remain small. Some tests already exist to detect gastric cancer but they suffer from inherent drawbacks making them insufficient responses for this public health issue. The two main tests are the non invasive carbon urea breath test which goal is to detect gases produced by helicobacter pylori bacteria signaling the presence of a tumor inside the stomach and the classical gastrointestinal endoscopy which allows visual inspection of the inner stomach surface. However, both methods have strong limitations. The carbon urea breath test isn't considered reliable enough due to possible other sources for the detected gases and the gastrointestinal endoscopy is highly uncomfortable (it requires local anesthesia at least) and is thus usually only performed after the patient feels the first symptoms. Moreover, parts of the stomach where tumors usually appears are difficult to reach with a typical endoscope. Furthermore, this procedure is costly. The main goal of this project is the design and construction of a custom computer-controlled navigation mechanism and robotic approach to deliver a tethered capsule to reach spaces within the stomach and analyze the H. pylori sample in situ, combining the advantages and avoiding the limitations of the more classical procedures: a reliable, rapid, easy to use, comfortable and cheap way to detect gastric cancer.
