Loss of heterozygosity (LOH) was analyzed in four patients with endometrial hyperplasia (EH) with atypia (two patients) and without atypia (two patients) and in five patients with endometrial adenocarcinoma (EAC) to clarify the clinicopathologic relationship between genetic alterations and hormone therapy. Each patient was initially administered high-dose medroxyprogesterone acetate (MPA) as a uterine-sparing treatment. The five microsatellite markers used to analyze LOH were at chromosomal loci 8p22.1, 8p21, 8p21.3, 8p22, and 8p22. DNA was extracted from paraffin-embedded sections before, during, and after MPA therapy using laser capture microdissection. As a result, LOH was more frequently detected after MPA therapy (overall ratios were 16, 17, and 29% before, during, and after MPA therapy, respectively). LOH is more easily detected in EH loci than in EAC loci before MPA. For EAC, initial LOH detection on chromosome 8 may be related to an incomplete response to MPA, but negative LOH does not guarantee a favorable treatment outcome. For EH or atypical endometrial hyperplasia, it is unknown whether LOH alteration associated with MPA therapy is related to atypia of the disease.

ObjectiveTo evaluate oncologic and reproductive outcome with levonorgestrel-releasing intrauterine system combined with gonadotropin-releasing hormone agonist in women with grade 1 endometrial carcinoma, and the levonorgestrel monotherapy in women with complex atypical hyperplasia.Materials/MethodsA prospective study was conducted. We analyzed the clinical characteristics of 70 patients younger than 42 years (mean age, 33 years) with a diagnosis of complex atypical endometrial hyperplasia (AEH) or grade 1 endometrial adenocarcinoma who were treated with hormonal therapy at the Division of Gynecologic Oncology of P.A. Hertsen Moscow Cancer Research Institute from February 2009 to December 2012. Patients with complex AEH received monotherapy with levonorgestrel-releasing intrauterine system (Mirena, Shering, Finland; 52 mg). Patients with a diagnosis of grade 1 endometrial cancer were treated with levonorgestrel-releasing intrauterine system combined with gonadotropin-releasing hormone agonist (Zoladex; AstraZeneca UK Limited, UK; 3.6-mg depot). All the patients received hormonal therapy for a minimum of 6 months. Pretreatment evaluation consisted of transabdominal and transvaginal ultrasound in grayscale, color Doppler ultrasound, contrast-enhanced magnetic resonance imaging,cervical hysteroscopy, Pipelle endometrial biopsy, and morphological and immunohistochemical characteristics of the tissue.ResultsSeventy patients were included in study analyses. Twenty three (72%) of 32 patients with adenocarcinoma and 35 (92%) of 38 patients with AEH had complete remission, defined as the absence of any carcinoma or hyperplasia on endometrial sampling specimens. Among these cases, 2 patients with adenocarcinoma and 1 patient with AEH had recurrence after their complete response. Nine patients had persistent disease. Eight patients had 10 conceptions, resulting in 8 live births.ConclusionsThe suggested conservative treatment strategy can be considered as a valid therapeutic option for young women of childbearing potential with atypical endometrial hyperplasia and grade 1 endometrial adenocarcinoma who wish to preserve their fertility and thus may be recommended as an alternative to hysterectomy. Close follow-up during and after the treatment period is strictly required.

Benign Course

Endometrial adenocarcinoma in women under the age of forty presents a different course according to its histology. Adenocarcinomas of the endometrium may be classified into 4 main types: type 1, homologous or endometrioid; type 2, fallopian-like; type 3, cervical-like; type 4, unclassifiable. The majority of homologous adenocarcinomas have a relatively benign course, whereas the other types are definitely malignant. There is no room for doubt between adenocarcinoma and atypical endometrial hyperplasia in women under forty unless the histological pattern is of the homologous or endometrioid type, because the other patterns are definitely malignant.
