ABSTRACT
GOALS OF THE WORK: In cancer patients, there is an ongoing interest in evaluating the impact of therapeutic interventions on health-related quality of life (hrqol). However, only a few longitudinal studies are published being able to measure the influence of therapy for the patients' quality of life. Based on these data, our aim was to evaluate changes of hrqol during the course of adjuvant radiotherapy in breast cancer patients with special focus on subgroup analysis. MATERIALS AND METHODS: Sixty-one women undergoing radiotherapy after breast conserving surgery were asked to answer the EORTC Quality of life questionnaire (EORTC-QOL-C30) three times: at the beginning of radiotherapy, in the forth week and 6 weeks after the end of treatment. To identify patients with changes of their qol during the observation time, the function scale "Global health status/Quality of life" was used enabling us to classify three subgroups: (1) unchanged hrqol (NC), (2) increasing hrqol (INC), (3) decreasing of hrqol (DEC). MAIN RESULTS: Patients with an increasing hrqol (N = 25) demonstrated a significant increase in the role as well as in the emotional functioning scales. In patients with a decreasing hrqol (N = 15), no changes in any of the function scales were found, while a significant decrease in their cognitive functioning was observed in patients with no change in hrqol (N = 21). CONCLUSIONS: Although the interpretation of these data is difficult because only a few data are available to compare our results, it could be demonstrated that emotional support and the ability to maintain a daily routine in additionally irradiated breast cancer patients is important to optimise hrqol. If hrqol decreases during the course of radiotherapy, the function scales of the EORTC-QOL-C30 seem to be insensitive to reflect this decrease.

AIM: Evaluation of the influence of histopathologic sub-types and grading of primaries of oesophageal cancer, relative to their size and location, on the uptake of (18)F-deoxyglucose (FDG) as measured by positron emission tomography (PET). METHODS: 50 consecutive patients were evaluated. There were four drop-outs due to previous surgical and/or chemotherapeutical treatments and thus in 46 patients (28 squamous cell carcinomas and 18 adenocarcinomas) a pretherapeutic PET evaluation of the primary including a standard uptake value (SUV) was obtained. In 42 cases data on tumour grading were available also. RESULTS: Squamous cell carcinomas (SCC) were in 7/13/8 cases located in the proximal, medial and distal part of the oesophagus, respectively the grading was Gx in 3, G 2 in 12, G2-3 in 7, and G3 in 6 cases. The SUV(max) showed a mean of 6.5+/-2.8 (range 1.7-13.5). Adenocarcinomas (ACA) were located in the medial oesophagus in two cases and otherwise in its distal parts. Grading was Gx in one, G2 in 4, G2-3 in 3, G3 in 3, G3-4 in 3, and G4 in one case. The mean SUV(max) was 5.2+/-3.2 (range 1-13.6) and this was not significantly different from the SCC. Concerning the tumour grading there was a slight, statistically not relevant trend towards higher SUV(max) in more dedifferentiated cancer. DISCUSSION: SCC and ACA of the oesophagus show no relevant differences in the FDG-uptake. While there was a significant variability of tumour uptake in the overall study group, a correlation of SUV and tumour grading was not found.
