Table 5.
Dosimetric comparison of the scalp of the patients who had persistent alopecia at 9 months compared with the scalp of the patients who had complete recover within 9 months: mean values and standard deviations (in brackets) of dosimetric variables.
| ROI | n | Mean D0.1cc (Gy) | Mean Dmean (Gy) | Mean V16 Gy (cc) | Mean V20 Gy (cc) | Mean V25 Gy (cc) | Mean V30 Gy (cc) | Mean V35 Gy (cc) | Mean V40 Gy (cc) | Mean V43 Gy (cc) |
|---|---|---|---|---|---|---|---|---|---|---|
| Scalp patients with alopecia at 9 month−follow up | 8 | 53.2 (± 4.1) | 14.1 (± 4.4) | 78.7 (± 31.3) | 57.8 (± 25.0) | 40.1 (± 17.4) | 28.4 (± 12.7) | 19.6 (± 9.7) | 12.6 (± 8.4) | 8.7 (± 7.6) |
| Scalp patients with complete recovery from alopecia within 9 months after RT | 66 | 46.7 (± 10.6) | 11.6 (± 4.7) | 66.8 (± 39.3) | 49.5 (± 35.4) | 34.7 (± 29.9) | 23.4 (± 24.3) | 14.8 (± 18.7) | 8.9 (± 13.3) | 6.4 (± 10.4) |
| p-value from Mann-Whitney Test | 0.12 | 0.09 | 0.29 | 0.34 | 0.24 | 0.14 | 0.053 | 0.028 | 0.036 | |
D0.1cc, dose received by 0.1 cc; Dmean, mean dose; VxGy, percentage of the scalp volume receiving ≥ x Gy.
