ABSTRACT
BACKGROUND/AIM:
Hormonal treatment is the preferred initial systemic therapy for patients with advanced or recurrent G1 or G2 endometrial cancer (EC) in terms of efficacy, toxicity, and economy. Few reports are available on the topic and we, therefore, conducted a retrospective study. PATIENTS ANDMETHODS:
Patients with EC who received high-dose medroxyprogesterone (MPA) at our Hospital between January 2010 and December 2022 were reviewed. Patients who were treated for fertility preservation or had a history of systemic chemotherapy other than adjuvant therapy were excluded.RESULTS:
Sixteen patients who were eligible for study inclusion had recurrent G1 or G2 EC. Their median age was 65 years (range=51-82 years), median body mass index was 22.6 kg/m2 (range=15.3-43.2 kg/m2), and all patients had an ECOG Performance Status of 0. All patients received 200 mg/day of MPA, and eight patients concomitantly received 100 mg/day of aspirin. None of the patients experienced severe adverse events. One patient had grade 2 deep vein thrombosis. Two patients discontinued MPA treatment because of adverse events. The response rate was 44% [95% confidence interval (CI)=20-68%] and median progression-free survival (PFS) was 6.9 months (95% CI=7.5-26 months). Four of 16 patients had PFS longer than 12 months, all of whom had positive tissue estrogen receptor (ER) and progesterone receptor (PR), and PFS at 2 years was 35% (95% CI=10.2-59.8%).CONCLUSION:
Hormone therapy is effective long-term in ER- and PR-positive EC and can be recommended as initial systemic therapy. Toxicity is mild and manageable.Palavras-chave
