NCI Definition: A poorly differentiated transitional cell carcinoma characterized by the presence of malignant cells with spindle cell morphologic features. [1]

Sarcomatoid transitional cell carcinomas most frequently harbor alterations in TP53, CDKN2A, KRAS, KMT2D, and KDM6A [2].

Most Commonly Altered Genes in Sarcomatoid Transitional Cell Carcinoma

TP53 c.217-c.1178 Missense, TP53 Mutation, TP53 Missense, TP53 Exon 7 Mutation, and TP53 Codon 245 Missense are the most common alterations in sarcomatoid transitional cell carcinoma [2].
