. The kit is suitable for the initial diagnosis and treatment of patients with non-small cell lung cancer and the diagnosis and treatment at the time of relapse, and can provide patients with guidance on the use of targeted drugs.

The advantage of being the first to obtain a certificate is that related companies can be deployed in the top three hospitals more quickly than their peers, seize the market, and gain a first-mover advantage. Han Yusheng said in an interview in 2018 that 80% of cancer patients in China are concentrated in top three hospitals or cancer specialist hospitals in first-tier cities. There are about 100 such hospitals in China. Because the second-generation sequencer is expensive, each company’s product is bound to the kit, it is difficult for a hospital to have more than two companies’ products. Once doctors form the habit of using the first product to land, they will become a barrier to entry for the latecomers.
