Nasopharyngeal cancer (NPC) is the most frequent among head and neck malignant tumor, which has a very high degree of malignancy. CT-scan is chosen in most hospitals as a radiological modality for NPC. The aims of this study was to know the validity of CTscan on diagnosis and evaluation of NPC. A retrospective observational diagnostic test was conducted to assess the presence of NPC on CT-scan results, as evidenced by the gold standard of biopsy, between December 1, 2009 through February 28, 2012 in Sardjito Hospital Yogyakarta. The value of interobserver agreement from three radiologists who evaluate CT scan for NPC is very strong. Total of 224 patients consist of 150 men and 74 women, with mean age of 47 years, showed 93% WHO type III, with the ratio of male and female of 2:1. The validity of entire CT-scan on NPC had sensitivity 85%, specificity 49%, and accuracy 66%. The highest sensitivity, specificity and accuracy on MSCT in the diagnosis were 88%, 67% and 83%, respectively. The high enough of validity and always found a thickening or a mass in the nasopharynx, and most of the asymmetry of tubarius torus and fossa Rosenmuller, these abnormalities on CT-scan could be used as a parameter to determine the diagnosis and evaluation of NPC.
