- OBJECTIVES: To compare two patient populations with assumed cultural differences undergoing radical cystectomy and orthotopic bladder substitution to determine whether these translate into differences in the answers to self-report instruments. METHODS: The questionnaires Functional Assessment of Cancer Therapy-Bladder Cancer (FACT-BL), consisting of a general version (FACT-G) and a bladder cancer specific module, and Hospital Anxiety and Depression Scale (HADS) were used preoperatively and 3 and 12 months postoperatively to assess patient well-being, urologic symptoms, depression, and anxiety in 29 and 32 Swedish and Egyptian male patients, respectively. RESULTS: Significant differences were found between the two groups. Higher FACT-G scores (ie, better outcomes) were obtained in the Swedish patients, both preoperatively and 3 months postoperatively, but not after 12 months. Differences were also seen in the urogenital assessment provided by the FACT-BL module. HADS revealed more depression among the Egyptian patients throughout the study period. Also, anxiety was more common preoperatively and 3 months postoperatively in the Egyptian patients, but not after 12 months. CONCLUSIONS: Swedish men scored better than Egyptian men on the FACT-BL and HADS, although the latter improved with time after surgery. These results show that patient-assessed outcomes differ in patients from different sociocultural backgrounds. This should be recognized when analyzing results from comparative studies. Also, the use of culture-fair instruments is important when assessing patients with different sociocultural backgrounds.

- OBJECTIVES: To evaluate positron emission tomography with C11-acetate as a method for detecting and localizing prostate cancer recurrence. No technique for localizing and detecting prostate cancer recurrence after biochemical relapse available today is sensitive enough to localize recurrence at a stage at which salvage radiotherapy is still curative. METHODS: Twenty patients (age 56 to 77 years) who had undergone radical prostatectomy and had an increasing prostate-specific antigen level measured on two consecutive occasions were included. In addition to the investigations usually performed when prostate cancer recurrence is suspected, they underwent positron emission tomography with C11-acetate as the marker. RESULTS: Pathologic uptake of acetate was seen in 15 (75%) of the 20 patients. In 8 of these patients, a solitary lesion was found (seven in the prostatic fossa and one at the regional lymph nodes). Multiple lesions were found in the remaining 7. False-positive uptake was seen in 3 men (15%). Additional investigations in these men revealed pathologic findings other than prostate cancer. CONCLUSIONS: Positron emission tomography with C11-acetate as marker is a promising method for early detection and localization of prostate cancer recurrence. False-positive uptake does occur.
