Results CT-Based Changes in Tumor Size after Two Cycles of Chemotherapy Across the study cohort, the Wilcoxon signed-rank test showed a highly significant decrease in tumor diameter on CT (p<0.001) after two cycles of chemotherapy (mean size before therapy = 3.7 cm; range = 1.4–9.3 cm; mean size after two courses of chemotherapy = 2.8 cm; range = 0.7–7.3 cm).
