- Fig 1.
Manual tracing of tumor area on gadolinium-enhanced, fat-suppressed T1-weighted (TR/TE, 500/15) image. The outlines show tumor areas (S) on MR image of 69-year-old man with squamous cell carcinoma in the tongue.

Graph (box plots) shows primary tumor volumes of oral and maxillary sinus (A) and pharyngeal (B) cancers categorized at T1–T4. The horizontal line is a median (50th percentile) of the measured volumes, the top and bottom of the boxes represent 25th and 75th percentiles, respectively, and whiskers indicate the range from the largest to smallest observed data points within 1.5 interquartile range presented by the box. P, Mann-Whitney U test.

Graph (box plots) shows primary tumor volumes of oral and maxillary sinus (A) and pharyngeal (B) cancers in patients with (+) or without (−) metastatic lymph node in the neck. P, Mann-Whitney U test.
- Fig 4.
Matrix patterns show distributions relative to primary tumor volumes, of metastatic nodes at neck levels (I–VI) of patients with oral and maxillary sinus (A) or pharyngeal (B) cancer. The multiplicity of metastatic nodes at each level of the neck is expressed as >50% (dark box) or ≤50% (gray box) of patients with corresponding tumor size range (cm3) having multiple nodes at that neck level or as no patient having metastatic nodes at that level (white box).
