In 2019, the Bladder Cancer Molecular Taxonomy Group (BCMTG) presented a consensus molecular classification comprising six subtypes of muscle-invasive bladder cancer (MIBC). The non-luminal subtypes were the most consistent with previous models. Subsequent studies in 2019 have revealed molecular heterogeneity among the luminal subtypes and their possible clinical ramifications.

2019年，膀胱癌分子分类学组（BCMTG）提出了一个共识分子分类法，该分类法包括六种类型的肌肉浸润性膀胱癌（MIBC）。非管腔亚型与以前的模型最一致。2019年的后续研究表明，管腔亚型之间的分子异质性及其可能的临床后果。
