| External Beam (Malaker et al.) | Brachytherapy (Duex et al.) |
| No. of Keloids | 86 | 22 |
| Radiotherapy Dose | 3750 cGy in once weekly | 1800 cGy in 6F × TID |
|
| 750 cGy/fraction × 5 weeks | 300 cGy/F 9 am, 3 pm, 9 pm |
| Duration of treatment | 35 days | 2 days |

| Observations | Most effective independent of radiobiological restriction | Highly effective short treatment period compliant with accepted brachytherapy-radiobiology, but independent of fraction radiobiology require brachytherapy facility |
|
| Easily adopted in any basic radiotherapy center | Hence restricted due to logistics |
