Univariate analysis of tumor growth rate (TGR)
| All lesions (n=37) | Irradiated lesion (n=13) | Non-irradiated lesions (n=24) | |||||||
| Progressive disease | Wilcoxon p value | Progressive disease | Wilcoxon p value | Progressive disease | Wilcoxon p value | ||||
| No | Yes | No | Yes | No | Yes | ||||
| Sum of diameters prebaseline (mean) | 95.00 | 95.50 | 0.93 | 40.25 | 41.00 | 0.57 | 54.75 | 54.50 | 1.00 |
| Sum of diameters baseline (mean) | 98.38 | 111.25 | 0.93 | 41.13 | 45.00 | 0.44 | 57.25 | 66.25 | 1.00 |
| Sum of diameters at first evaluation (mean) | 60.00 | 111.25 | 0.28 | 24.00 | 31.25 | 0.27 | 36.00 | 80.00 | 0.37 |
| REF-TGR (mean) | 32.75 | 40.69 | 0.37 | 46.04 | 24.14 | 0.73 | 39.03 | 71.28 | 0.55 |
| Exp-TGR (mean) | −39.37 | −0.22 | 0.073 | −37.57 | −29.39 | 0.93 | −45.76 | 46.82 | 0.016 |
| ΔTGR (mean) | −72.12 | −40.91 | 0.81 | −83.61 | −53.54 | 0.93 | −84.79 | −24.46 | 0.46 |
TGR is evaluated in percentage per months. ΔTGR = (EXP-TGR) – (REF-TGR). A negative value corresponds to a slowdown of the tumor growth.
