Lesion distribution features
The Derkay score was 10±5.9 in patients with JO-RRP and 6.5±4.3 in
patients with AO-RRP, and patients with JO-RRP had higher Derkay scores
than patients with AO-RRP, and the difference between the two was
statistically significant (p=0.001).
In the JO-RRP group, anatomical site involvement was the most common
glottis, with 58 cases (98.3%) involving the glottis, followed by
supraglottic and subglottic cases with 54 cases (91.5%) and 35 cases
(59.3%), respectively. These patients underwent RRP resection and were
transferred to Shanghai Pulmonary or Chest Hospital for further
diagnosis and treatment.In AO-RRP patients, anatomical site involvement
was also the most common glottis, 102 (93.6%) involved glottis,
followed by supraglottic and subglottic 50 (45.9%) and 22 (20.2%),
