Quality of Life after Preoperative Radio-/Chemotherapy in Locally Advanced Breast Cancer Patients.

e12083 Background: Preoperative radiotherapy and chemoradiotherapy (PRT/PCRT) represents an increasingly used clinical strategy in different tumor sites. However, concerns regarding a possible unfavorable influence on the clinical outcome still exist. The aim of the current study was to examine the long-term global health status in our series of LABC patients treated with PRT/PCRT followed by breast-conserving surgery (BCS) or mastectomy (ME). Methods: Of the 315 patients treated with PRT/PCRT in the years 1991 and 1999, 203 patients were still alive at long-term follow up of mean 17.7 years (range 14-21). Thirty-seven patients were lost to follow up and 58 patients refused to be contacted, which resulted in 107 patients (64 patients after BCS and 43 after mastectomy) being available and willing to undergo further clinical assessment. PRT/PCRT consisted of external beam radiation therapy (EBRT) with 50 Gy (5 × 2 Gy/week) to the breast and the supra-/ infraclavicular lymph nodes combined with a consecutive electron boost or (in case of BCS) a 10-Gy interstitial brachytherapy boost with Ir-192 prior to EBRT. Overall, chemotherapy was administered either prior to RT or concomitantly in the majority of patients. Quality of life (QoL) was assessed by EORTC QLQ-C30 questionnaires for overall QoL and EORTC QLQ-BR23 for breast-specific QoL. Results are reported using functional scales (body image, sexual functioning, sexual enjoyment, and future perspective) and symptom-related items (systemic therapy side effects, breast symptoms, arm symptoms, and upset by hair loss). The results were compared to a published reference cohort of n=2028 healthy adults (16-92 years), including n=1139 women (age 16-92 years). EORTC QLQ-C30 functional scales were also analyzed between different subgroups including an age-matched analysis with a two sided paired t-test. Results: In comparison with this healthy control group of 1139 women, we did not detect any significant differences for the functional scales measured by physical function, emotional well-being, cognitive, and social function as well as the symptom scales: fatigue, nausea, vomiting, pain, diarrhea and financial difficulties for both groups. However, significant inferior scores were found in the present study group regarding obstipation (p=0.013), loss of appetite (0.038), sleeping disorder (p=0.01) and dyspnoe (p=0.01). Conclusions: Taken together, retrospective as well as prospective data underline the feasibility of preoperative radiotherapy in breast cancer.
