HF vs CF Whole-Breast Irradiation

Studying toxic effects, fatigue, and family needs

Compared to conventional fractionation (CF), hypofractionation (HF) appears to yield lower rates of acute toxic effects, less fatigue, and less trouble meeting family needs, according to a study of women aged 40 years or older with stage 0 to II breast cancer for whom whole-breast irradiation was recommended, including 149 patients randomized to CF and 138 to HF. Researchers found:
