Abstract. In a complete geographic series of 155 cases of primary uterine sarcomas, prophylactic pelvic irradiation was used as standard postoperative therapy in the majority of the cases. Vaginal brachytherapy was also added as a boost. The histology was leiomyosarcoma in 62 cases (40%), carcinosarcoma in 60 (39%), endometrial stromal sarcoma in 25 (16%), and other types in 8 cases (5%). The primary surgery was extended hysterectomy in 11 cases (7%), simple hysterectomy in 110 (71%), and supravaginal hysterectomy in 12 (8%). In 22 cases (14%) no major surgery was possible. In the complete series, 62 recurrences (40%) were recorded. Local (9%), regional (9%), and distant recurrences (28%) were the most frequent. The type of surgery was associated with the risk of tumor recurrence. Extended surgery reduced the risk of local and regional recurrences. The 5-year overall survival rate was 42% and the recurrence-free survival (RFS) was 37%. The number of mitoses was significantly (P=0.007) associated with survival. The locoregional RFS rate was 75% for patients treated with adjuvant irradiation and 83% for patients treated with primary surgery alone. Serious late tissue reactions from the bladder and intestine occurred in 7% of the irradiated cases. The locoregional tumor control rate was high in this series of patients, but no significant difference was found between patients treated with surgery alone and surgery plus postoperative pelvic irradiation. This was true for all histological subtypes of the uterine sarcomas. However, this was not a randomized study and selection bias cannot be ruled out.

Objective.Polyvinyl chloride (PVC) is commonly used as a catheter material in catheters for clean intermittent catheterization (CIC) but, owing mainly to environmental concerns, a PVC-free material has been proposed. The objective of this study was to compare patients' tolerability for catheters made of PVC and a newly developed PVC-free material. Material and methods.This was a prospective, randomized, crossover study in 104 male patients with maintained urethra sensibility who practised CIC. The patients evaluated in a randomized order a PVC and a PVC-free LoFric® catheter after 1 week's use of each. The material properties and tolerability, i.e. reported perceived discomfort, of each catheter were compared and adverse events documented. Results.Twenty-nine (28%) and 15 (14%) patients reported discomfort when using the PVC catheter and the PVC-free LoFric catheter, respectively. A comparison showed that five patients (5%) reported discomfort with the PVC-free and not with the PVC catheter, and 19 patients (18%) reported discomfort with the PVC and not with the PVC-free catheter (p = 0.0066). Forty patients reported a total of 91 adverse events, of which the most common were discomfort in terms of pain, a burning sensation and bleeding. Conclusions.Generally low discomfort rates were reported in the study population, suggesting a high tolerance for CIC with catheters of both the PVC and the PVC-free materials. The lowest discomfort was, however, found when CIC was performed using the PVC-free LoFric catheter.
