description | Background: The use of shorter radiotherapy schedules has an economic and
logistic advantage for radiotherapy departments, as well as a high degree of patient
convenience. The aim of this study is to assess the acute and short-term late toxicities
of a hypofractionated radiotherapy schedule with a concomitant boost.
Methods: We enrolled 57 eligible patients as group A. These patients received 42.5
Gy in 16 fractions of 2.66 Gy each to the whole breast over 3.2 weeks. A concomitant
electron boost of 12 Gy in 16 fractions was also administered which gave an additional
0.75 Gy daily to the lumpectomy area for a total radiation dose of 54.5 Gy. Toxicity
was recorded at three weeks and at three months for this group as well as for a control
group (group B). The control group comprised 76 eligible patients treated conventionally
with 50 Gy to the whole breast over five weeks followed by a sequential electron boost
of 12 Gy in 2 Gy per fraction.
Results: There were no statistically significant differences observed in the incidence
of acute skin toxicity, breast pain, and edema recorded at three weeks or pigmentation
and fibrosis recorded at three months between the two groups (P<0.05). Acceptable
toxicity occurred in both groups with no grade 3 or higher complications. Chest wall
separation was highly correlated with toxicity in both groups (P<0.001) while age showed
no correlation (P>0.05).
Conclusion: The results of this study suggest there are no increased acute and shortterm
late toxicities affiliated with the hypofractionated schedule plus a concomitant boost
as prescribed compared to the conventional fractionation of adjuvant breast radiotherapy.
Large randomized trials and long-term follow-up are needed to confirm these favorable
findings. |
