| Popis: | Aims and background Uterine serous cancer is associated with a poor outcome and poses a therapeutic challenge. We retrospectively evaluated the experience of the Radiotherapy Department of the University of Florence. Methods Forty-three patients with stage I-III uterine serous cancer underwent surgery with (18 patients, group 1) or without complete surgical staging (25 patients, group 2) followed by adjuvant whole pelvic radiotherapy alone or combined with vaginal brachytherapy (in 35 and 8 cases, respectively). The median dose delivered with whole pelvic radiotherapy was 50Gy (range, 45–56) and for brachytherapy was 20 Gy (range, 20–30). Results Actuarial overall survival and disease-free survival rates at 5 years were 62.5% and 61%, respectively. Local failure was observed in 17 patients (39.5%) and distant metastasis in 10 (23.2%). Nine patients had both local failure and distant metastasis, which had developed concurrently in 7 cases. Isolated abdominal failure occurred in 4 cases (9.3%). Local relapse was noted in 22.2% of patients in group 1 compared to 52% in group 2. A trend towards a better 5-year overall survival (67.2% vs 58%), disease-free survival (63% vs 59%) and local control (70% vs 59%) was observed in group 1 than group 2, although the difference between the two groups failed to reach statistical significance. Conclusions Given the patterns of failure of patients with uterine serous cancer, adjuvant whole pelvic radiotherapy may be a reasonable approach, although novel integrated strategies are needed because the results achieved remain disappointing. Adjuvant whole pelvic radiotherapy might improve overall survival, disease-free survival and local control in complete surgically staged patients, but further investigations are required. |
