ABSTRACT
PURPOSE: To confirm our assumptions regarding factors that apparently cause psychological distress related to adjuvant radiotherapy in breast cancer patients and to evaluate variables that can predict therapy-associated distress. METHODS AND MATERIALS: Between January 1997 and April 1998, 111 women (33-84 years) with early-stage breast cancer were irradiated (56 Gy) after breast-conserving surgery. Patients were given self-assessment questionnaires on the first and last day of radiotherapy. Statistical analysis was performed using the structural equation model LISREL, variance analysis, and regression analysis. RESULTS: The internal subject-related factors (coping, radiation-related anxiety, physical distress, psychological distress) reciprocally influenced each other, whereas external radiotherapy-specific factors (environmental influence, confidence in the medical staff) were causally related to coping, anxiety, and distress. Fifty-three percent of the women felt distressed because cancer affected the breast; 48% were initially afraid of radiotherapy. For 36%, anxiety was not reduced during treatment. Highly distressed women were identified by the following parameters: < or =58 years; initial anxiety; they were affected by having breast cancer, were negatively affected by environmental factors, and did not find distraction helpful. CONCLUSION: Despite considerable individual variability in breast cancer patients, it seems possible to identify women who run a high risk of therapy-associated distress. In these patients, psychosocial support is necessary to reduce treatment-related anxiety and to stabilize confidence in the medical staff.

BACKGROUND: In literature there are only few informations about the influence of postoperative irradiation on the psychological health of breast cancer patients treated by breast-conserving surgery. However, psychological distress and anxiety related to irradiation are often observed. Purpose of our study was the evaluation of the influence of radiotherapy-induced distress in these patients. PATIENTS AND METHODS: Between October 1995 and June 1996 in 48 breast cancer patients (31 to 76 years old) treated by breast-conserving surgery adjuvant irradiation with or without systemic therapy was applied. On the first and the last day of radiotherapy they were given a questionnaire (Table 1) which was designed together with psychologists. Covering different situations related to radiotherapy the construction of items are determined by factors with possible influence on psychological distress and perception with regard to irradiation. RESULTS: Most of the women (92%) stated to be well informed about the irradiation and tried to obtain further information about this treatment (83%). 56% tried not to think about radiotherapy and/or to distract themselves (81%). 40% were anxious about the fact to undergo irradiation. In the end of treatment 77% reported to have been anxious only initially or never; only 19% were anxious almost or most of the time. 35% were worried about the expected cosmetic alterations of their breast; only 30% observed acute cosmetic changes. With regard to situation-related distress all patients (100%) stated that the communication with the medical staff made it easier to stand the irradiation treatment. CONCLUSIONS: In spite of theoretical considerations our results are explorative in character. However, following statements seem to be important: 1. A large requirement exists to get information about radiotherapy. 2. The patients experience irradiation treatment more positive than initially expected by themselves. 3. With regard to radiotherapy anxiety is reduced during the course of treatment. Here the psychosocial care of the medical staff is an important support for reduction of anxiety.
