Peritoneal carcinoma index in computed tomography assessment of Peritoneal carcinomatosis
Peritoneal carcinomatosis is a serious complication of numerous neoplasm. The therapeutic approach requires reproducible staging. Peritoneal carcinoma index (PCI) is an accepted method for the computed tomography assessment. The aim is to share the author’s experience in CT evaluation of peritoneal spread of tumors by PCI. Computed tomography of the abdomen and pelvis of 35 patients (13 men/22 women, age range 43-85) with peritoneal carcinomatosis are included in the study. The preliminary clinical diagnosis were n=15 of ovarian origin, n=10 of colorectal origin, n= 9 of gastric origin and 1 patient with endometrial cancer. CT examinations were performed on a 16-slices CT scanner (Somatom Sensation 16; Siemens Medical Solutions) with standard protocol. The most common finding was ascites, followed by softtissue infiltration of the omentum and peritoneal implants. Central and left lower regions according to the Sugarbacker system were the most commonly involved areas. Computed tomography allows specifying PCI in peritoneal carcinomatosis. Staging is important for patients management.
