Uterine leiomyosarcoma--a Singapore experience.

Uterine leiomyosarcoma is an aggressive tumour. In our retrospective series of 27 patients, there were 25 with nonmyxoid high-grade leiomyosarcoma of the uterus. The stage distribution was Stage 1, 16; Stage 3, 5 and Stage 4, 4. In the patients with Stage 1 disease, 3 of the 8 patients who received adjuvant chemotherapy subsequently developed recurrent disease. In contrast, 6 of the 8 patients who did not receive adjuvant chemotherapy subsequently developed recurrent disease; 2 of the patients in the latter group also received adjuvant radiotherapy. Six of the 9 women with recurrences were distant 'failures' alone, 2 were both distant and pelvic 'failures' and 1 was pelvic 'failure' alone. All the patients with advanced-stage disease eventually succumbed to the disease despite the therapies given. This study is small and retrospective but it suggests that there might be a role for adjuvant chemotherapy in the management of the early stage of this disease.
