Introduction: Standard treatment for early-stage invasive breast cancer (bca) consists of breast-conserving surgery and several weeks of adjuvant radiotherapy (rt). Neoadjuvant single-fraction rt is a novel approach for early-stage bca. We sought to investigate the effect of delaying surgery after neoadjuvant rt with respect to the rate of pathologic response (pr). Methods: Women 65 years of age or older with a new diagnosis of stage i luminal A bca were eligible for inclusion. A single 20 Gy dose to the primary breast tumour was given, followed by breast-conserving surgery 3 months later. The primary endpoint was the pr rate assessed by microscopic evaluation using the Miller–Payne system. Results: To date, 10 patients have been successfully treated. Median age of the patients was 72 years (range: 65–84 years). In 8 patients, neoadjuvant rt resulted in a tumour pr with median residual cellularity of 3%. No immediate rt complications other than mild dermatitis were noted. Conclusions: This study demonstrates a method for delivering single-fraction rt that can lead to a high level of pr in most patients. Continued accrual to this study and subsequent trials are needed to determine the feasibility, safety, and role of this novel technique in the management of early-stage bca. Full article

Breast or chest-wall pain (bcp) is prevalent in 20%–50% of breast cancer survivors, and it affects quality of life (qol). To determine the feasibility and potential efficacy of an exercise program to improve patient qol and bcp, such a program was offered to breast cancer patients suffering from bcp. The study enrolled 10 breast cancer patients with moderate-to-severe bcp at 3–6 months after completion of all adjuvant treatments. These patients participated in a 12-week comprehensive health improvement program (chip). Intensity was adjusted to reach 65%–85% of the patient’s maximal heart rate. Before the chip and at 1 and 6 months after completion of the chip, qol and pain were measured using questionnaires [European Organisation for Research and Treatment of Cancer Quality of Life core and breast cancer modules (qlq-C30, -BR23) and the McGill Pain Questionnaire short form] completed by the patients. Results were compared with those from case-matched control subjects from another study at McGill University. After the chip, patients reported significant and clinically important improvements in qol and symptoms. At 1 and 6 months post-chip, patients in the study felt, on average, better in overall qol than did historical control subjects. Our study suggests that patients who experience chronic bcp may benefit from an exercise program. A randomized controlled trial is warranted. Full article

Purpose: Radiation-induced dermatitis is a common side effect of breast irradiation, with hypofractionation being a well-known risk factor. In the context of the widespread adoption of hypofractionated breast radiotherapy, we evaluated the effect of hypofractionated radiotherapy on the incidence of skin toxicity in patients receiving adjuvant chemotherapy. Patients and Methods: We retrospectively reviewed the records of patients with breast cancer treated from 2004 to 2006 at a single institution. Patients undergoing lumpectomy with or without adjuvant chemotherapy followed by hypofractionated radiotherapy consisting of 42.4 Gy in 16 fractions were included in the study. Using cosmetic and skin toxicity scales, all patients were evaluated weekly during treatment and at scheduled follow-up visits with the radiation oncologist. Results: During the study period, 162 patients underwent radiotherapy, and 30% of those (n = 48) received chemotherapy. Radiotherapy boost to the tumour bed was more common in the chemotherapy group [n = 20 (42%)] than in the radiotherapy-alone group [n = 30 (26%)]. We observed no statistically significant difference between the groups with regard to acute skin toxicity of grade 3 or higher (2.1% in the chemotherapy group vs. 4.4% in the radiation-alone group, p = 0.67) or of grades 1–2 toxicity (62.5% vs. 51.7% respectively, p = 0.23). There was also no significant difference in late grade 3 or higher skin toxicity between the groups (2.1% vs. 0% respectively, p = 0.30) or in grades 1–2 toxicity (20.8% vs. 25.5% respectively, p = 0.69). Similarly, excellent or good cosmetic result scores were similar in both groups (p = 0.80). Conclusions: In our single-institution review, we observed no adverse effects of chemotherapy in combination with hypofractionated whole-breast irradiation. Further investigations are necessary to better elucidate the effects of chemotherapy on skin toxicity in the context of hypofractionated irradiation. Full article
