Figures
Fig 1. Representative CT scans (pretreatment [A]; post-treatment [B]) show the response to chemoradiation of a pathologically abnormal node (open arrow) and a normal node (closed arrow). The pathologically abnormal node shows a volume reduction of 84%, and the normal node shows a volume reduction of 98%. The extracapsular spread seen in the pathologically abnormal node in the pretreatment scan is not seen in the post-treatment scan
Fig 2. Volume reduction of lymph nodes in response to chemoradiation. A, A significant (P < .01) volume reduction of 91 ± 4% is seen for the pathologically abnormal nodes. B, Volume reduction in the normal nodes, 55 ± 21%, is not significant (P > .1). Note the different scales between the panels
Fig 3. Histopathologic findings of resected lymph nodes.
A, Eighteen of 19 previously clinically positive lymph nodes show fibrosis and inflammation (original magnification, ×20).
B, In the other node (one of 19), a small focus of squamous cell carcinoma is apparent (arrows) (original magnification, ×20).
