Treatment of damaged, diseased, abnormal, obstructive, cancerous or undesired tissue (e.g. a tumor, a benign tumor, a malignant tumor, a cyst, or an area of diseased tissue, etc) is provided by delivering specialized pulsed electric field (PEF) energy to target tissue areas in a specific dose so as to obtain a superior outcome. The PEF energy and delivery has been optimized to provide advanced treatment of target tissue areas, including destruction of undesired tissue and generation of improved inflammatory and immune responses. These various types of treatment are controlled by a variety of factors including the electrode geometry, the dose of PEF energy delivered, the time the energy is delivered over, and the waveform of the PEF energy itself. The PEF energy is delivered in the form a dose which is considered to be one application of the specialized energy. Each dose creates a lesion in the target tissue area.

Familial adenomatous polyposis (FAP) patients harbor mutations in the APC gene and will develop adenoma and early colorectal cancer. Taking biopsies from non-adenomatous (NA) and adenomatous (A) colonic mucosa of FAP patients, we investigated the early events associated with FAP using the intestinal organoid model. In addition to their high proliferative capacity, NA- and A-organoids were characterized by cysts and cysts with buds, respectively, suggesting abnormal maturation. A-organoids were enriched in the stem cell marker LGR5 and dependent on EGF and TGFβ for their growth. Downstream of EGFR, AKT, β-catenin and YAP were found to be activated in A-organoids. While the p110β isoform of PI3K was predominant in A-organoids and essential for their growth, p110α was associated with the immature state of NA-organoids. Accordingly, the present invention relates to a method of treating Familial Adenomatous Polyposis in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a PI3K inhibitor.
