Concomitant chemoradiotherapy for patients with nonmetastatic breast carcinoma: side effects, quality of life, and...

This study was designed to investigate the personal experience of patients with nonmetastatic breast carcinoma who were treated with the concurrent administration of radiotherapy and chemotherapy in terms of side effects and quality of life (QL).

One hundred nine patients with nonmetastatic breast carcinoma, recruited between May 1995 and February 1997, were included in a protocol combining chemotherapy with mitoxantrone and cyclophosphamide, administered intravenously in 4 cycles of 21 days, and concomitant radiotherapy. Side effects of treatment and its impact on patients' daily lives were measured using ad hoc questionnaires; QL was measured by the European Organization for Research and Treatment of Cancer QLQ-C30 QL questionnaire, and pain was measured by a visual analogue scale (VAS).

All patients agreed to participate. The mean number of chemotherapy and radiotherapy symptoms per cycle were: 7.2+/-2.5 and 2.4+/-1.8, respectively. Chemotherapy symptoms generally were more frequent and distressing than those of radiotherapy. The average pain score reported on the VAS by patients during treatment was 3.0+/-2.0. Multidimensional QL assessment showed that treatment mainly affects physical functioning and global QL. Multivariate analysis showed that the main determinants of QL at the end of treatment were fatigue, pain, and loss of appetite experienced during treatment. Moreover, 62.8% of patients required specific help for transportation to the hospital and/or home upkeep.

The concurrent administration of chemotherapy and radiotherapy deteriorates patients' QL but in a proportion similar to sequential administration while presenting the advantage of a shorter duration of treatment. However, increased fatigue, pain, and loss of appetite as well as difficulties in patients' daily lives have to be taken into account in therapeutic decision-making analysis.
