Table 3 Association of symptomatic radiation pneumonitis and RGS assessed on computed tomography scans performed one month after thoracic radiation therapy
Occurrence of symptomatic RP CTCAE grade ≥ 2 | Fisher’s exact test | ||
|---|---|---|---|
RGS grade 0–1 (n = 29) | RGS grade 2–3(n = 10) | ||
RP – (n = 17) | 17 | 0 | RR 2.4, 95%CI 1.6–3.7, p < 0.01 |
RP + (n = 22) | 12 | 10 |
Onset of symptomatic RP within 8 weeks after RT (n = 22) | |||
|---|---|---|---|
RGS grade 0–1 (n = 12) | RGS grade 2–3 (n = 10) | ||
Days, median (range) | 104 (55–166) | 42 (24–111) | RR 4.8, 95%CI 1.3–17.6, p < 0.01 |
