Radiologic response of tumor in patients who received chemotherapy alone, followed by radiation with or without chemotherapy

	Treatment modality
	Before subsequent radiation	After subsequent radiation or chemoradiation
	n = 8 § median, range	n = 8 § median, range	P‐ value
Tumor volume measurement (cc)	94.3 (19.8–485.9)	54.4 (16.5–383.0)	0.03
Tumor diameter measurement* (cm)	7.5 (5.6–10.6)	6.5 (4.2–11.4)	0.049

cc, cubic centimeter; cm, centimeter; CI, confidence interval.

^*Largest axial diameter across all slices.

^§Eight patients received treatment with chemotherapy alone, followed by radiation with or without chemotherapy. The imaging response to each respective treatment modality (chemotherapy alone vs. chemotherapy and subsequent follow‐up treatment) were separately analyzed and compared to baseline.

Wilcoxon rank‐sum testing was used to compare tumor size between groups. A P‐value of <0.05 was considered statistically significant.
