Individual mean doses to the lung, heart, and total body were also highly significant in predicting lymphocyte nadirs (Spearman coefficients = –0.34, –0.502, and –0.36 respectively; P < .01).
Individual mean doses to the lung, heart, and total body were also highly significant in predicting lymphocyte nadirs (Spearman coefficients = –0.34, –0.502, and –0.36 respectively; P < .01).
Similar to RFS, log PTV was close to being statistically significant, with P values = 0.086 and 0.15, respectively.
Although lymphocyte nadir has been proven to affect OS in multivariable Cox regression, the KM survival curve only showed a trend of better survival in lymphocyte nadir ≥0.5 compared with that of <0.5.
