Urinary exfoliated tumor single-cell metabolomics technology for establishing a drug resistance monitoring system for bladder cancer with intravesical chemotherapy. (October 2020) - Tian, Junjie
Abstract: Bladder cancer is one of the most common urogenital malignant with a rising incidence rate all over the world. Non-muscle invasive bladder cancer (NMIBC) has the characteristics of high recurrence rate and easy progression after receiving transurethral tumor resection combined with intravesical chemotherapy. The intrinsic or/and acquired drug resistance is mainly causing this poor outcome. The continuing advances in metabolomics and single-cell mass spectrometry have been considered as the key to promoting clinical precision medicine. Urinary exfoliated tumor cells (UETCs) carry the first-hand biological information on the genesis and progression of primary bladder cancer. Therefore, we hypothesized that the establishment of a drug resistance monitoring system for bladder cancer with intravesical chemotherapy based on UETCs single-cell metabolomics technology has a broad application prospect.
