[Clinical significance of adjuvant endocrine therapy in treatment of endometrial carcinoma: study of 171 patients].

AbstractOBJECTIVE:
To study the effectiveness of adjuvant endocrine therapy on the prognosis of endometrial carcinoma and to analyze the influence of progesterone receptor on the curative effect of adjuvant endocrine therapy.
METHODS:
A retrospective study was carried out on 171 patients of endometrial carcinoma with similar pathological examination. 82 of the 171 patients with endometrial carcinoma (48.0%), aged (57 +/- 9) years, underwent endocrine therapy, mainly by progesterone (245 +/- 51) mg/d for (1.3 +/- 0.9) years. 55 cases (67.1%), aged (57 +/- 10) years, underwent endocrine therapy for more-than-one-year (more-than-one-year subgroup), and 27 cases (32.9%), aged (59 +/- 9) years, underwent endocrine therapy for less-than-one-year (less-than-one-year subgroup). 24 of the 82 patients (29.3%) underwent adjuvant radiotherapy. 89 of the 171 patients (52.0%), aged (57 +/- 11) years, were in the control group 31 of the 89 patients in the control group (34.8%) underwent adjuvant radiotherapy, and 39 patients (43.8%) underwent adjuvant endocrine therapy. Follow-up was performed by correspondence, phone call, or outpatient department visit for 3 approximately 4 years.
RESULTS:
The rate of recurrence and/or metastasis of the endocrine therapy group was 13.4%, not significantly different from that of the control group (23.6%, P > 0.05); the death rate of the endocrine therapy group was 12.2%, not significantly different from that of the control group (20.2%, P > 0.05). The rate of recurrence and/or metastasis of the less- than-one-year subgroup was 25.9%, significantly higher than that of the more-than-one-year subgroup (7.3%, P = 0.012); the death rate of the less- than-one-year subgroup was 22.2%, significantly higher than that of the more-than-one-year subgroup (7.3%, P = 0.036). Cox regression showed that stage, the operation, tumor cell differentiation, and duration of endocrine therapy significantly affected the recurrence/metastasis remarkably (OR = 5.199, OR = 0.507, OR = 1.796, OR = 0.538) and the death rater (OR = 5.488, OR = 0.482, OR = 1.516, OR = 0.547). The rate of recurrence/metastasis of the endocrine therapy group patients with positive progesterone receptor was 4.7%, significantly higher than that of the patients with negative progesterone receptor (26.7%, P = 0.034).
CONCLUSIONS:
The prognosis of endometrial carcinoma patients can be improved with adjuvant endocrine therapy, especially for those with positive progesterone receptor. Endocrine therapy should be continued no less than 1 year.
