The transforming growth factor-beta type II receptor (RII) is commonly
mutated in colon and gastric cancers with microsatellite instability (MI).
We utilized our series of lung cancers with MI and rare alleles of the
H-ras1 gene to determine the association between MI and RII mutations and
searched the entire RII coding region in 33 lung cancers with MI by
polymerase chain reaction-single-strand conformation polymorphism analysis.
We found no mutations, and these data support other recent evidence that
RII mutations rarely occur except in colon and gastric tumors with MI.
