[Impact of diagnostic imaging on: staging, results and follow-up of rhinopharyngeal carcinoma].
Ninety-seven patients affected with nasopharyngeal carcinoma (NPC) were examined with both conventional and Computed Tomography (CT) to evaluate the involved sites with both methods. CT staging was more accurate, showing involvement in more locations than conventional tomography, so that staging was modified in 23 of 97 patients. Two hundred and seventeen patients treated from 1970 to 1985 were subdivided into group A (111 patients who underwent conventional tomography only) and group B (106 patients examined with CT, from 1978 on). A trend toward more advanced stages at presentation was observed in group B; nevertheless, local control at 5 years was higher in group B (59%) than in group A (42%). The role of Magnetic Resonance (MR) imaging in NPC staging was also evaluated in 30 patients: there was disagreement in 2 cases. Involvement of different structures was shown in 10 of 28 cases with the same CT and MR staging. MR imaging proved a valuable tool in the follow-up as well: in fact, it clarified 12 questionable opacities on CT in a group of 35 followed patients as inflammatory lesions in 10 patients and tumors in 2.
