}Purpose of review The purpose of this review is to examine the contribution of the PI3K signaling pathway to the development of human tumors and to propose further studies to elucidate how to develop therapeutics for patients with mutations in this pathway. Recent findings More than 30% of various solid tumor types were recently found to contain mutations in PIK3CA, the catalytic subunit of PI3K. Further analysis of key genes in this pathway identified an additional eight genes altered in…

It is shown that patients with tumors harboring a PIK3CA mutation have a better clinical outcome than those with a wild-type Pik3CA gene, and this improved prognosis may pertain only to patients with mutations in the kinase domain of p110α and to postmenopausal women with estrogen receptor-positive breast cancer.

These data indicate that mutations of PIK3CA play an oncogenic role in substantial fractions of ovarian and breast carcinomas, and in consideration of mutation of other components of the PI3K-AKT pathway in both tumor types, confirm the major oncogens role of this pathway in ovarian and Breast carcinomas.

It is shown that PIK3CA is frequently increased in copy number in ovarian cancers, that the increased copy number is associated with increased Pik3CA transcription, p110α protein expression and PI3-kinase activity and that treatment with the PI3 -kinase inhibitor LY294002 decreases proliferation and increases apoptosis.
