OCSTAMP

Across TCGA pan-cancer cohorts, OCSTAMP Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated OCSTAMP data layer compared with 24 for mass-spec protein.

The strongest signal is observed in small cell lung cancer (SCLC), where higher OCSTAMP Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated OCSTAMP expression acts as an unfavorable survival marker.

SCLC, SARC, and ESCA are the cancer types where OCSTAMP Mutation most reproducibly stratifies survival.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
