National patterns of care and fertility outcomes for reproductive-aged women with endometrial cancer or atypical hyperplasia.

BACKGROUND: Although it is uncommon, the incidence of endometrial cancer and atypical hyperplasia among reproductive-aged women is increasing. The fertility outcomes in this population are not well described. OBJECTIVE: We aim to describe the patterns of care and fertility outcomes of reproductive-aged women with endometrial cancer or atypical hyperplasia. MATERIALS AND METHODS: A cohort of women aged ≤45 years with endometrial cancer or atypical hyperplasia diagnosed in 2000 to 2014 were identified in Truven Marketscan, an insurance claims database of commercially insured patients in the United States. Treatment information, including use of progestin therapy, hysterectomy, and assisted fertility services, was identified and collected using a combination of Common Procedural Terminology codes, International Statistical Classification of Diseases and Related Health Problems codes, and National Drug Codes. Pregnancy events were identified from claims data using a similar technique. Patients were categorized as receiving progestin therapy alone, progestin therapy followed by hysterectomy, or standard surgical management with hysterectomy alone. Multivariable logistic regression was performed to assess factors associated with receiving fertility-sparing treatment. RESULTS: A total of 4007 reproductive-aged patients diagnosed with endometrial cancer or atypical hyperplasia were identified. The majority of these patients (n = 3189; 79.6%) received standard surgical management. Of the 818 patients treated initially with progestins, 397 (48.5%) subsequently underwent hysterectomy, whereas 421 (51.5%) did not. Patients treated with progestin therapy had a lower median age than those who received standard surgical management (median age, 36 vs 41 years; P < .001). The proportion of patients receiving progestin therapy increased significantly over the observation period, with 24.9% treated at least initially with progestin therapy in 2014 (P < .001). Multivariable analysis shows that younger age, a diagnosis of atypical hyperplasia diagnosis rather than endometrial cancer, and diagnosis later in the study period were all associated with a greater likelihood of receiving progestin therapy (P < .0001). Among the 421 patients who received progestin therapy alone, 92 patients (21.8%; 92/421) had 131 pregnancies, including 49 live births for a live birth rate of 11.6%. Among the 397 patients treated with progestin therapy followed by hysterectomy, 25 patients (6.3%; 25/397) had 34 pregnancies with 13 live births. The median age of patients who experienced a live birth following diagnosis during the study period was 36 years (interquartile range, 33-38). The use of some form of assisted fertility services was observed in 15.5% patients who were treated with progestin therapy. Among patients who experienced any pregnancy event following diagnosis, 54% of patients used some form of fertility treatment. For patients who experienced a live birth following diagnosis, 50% of patients received fertility treatment. Median time to live birth following diagnosis was 756 days (interquartile range, 525-1077). Patients treated with progestin therapy were more likely to experience a live birth if they had used assisted fertility services (odds ratio, 5.9; 95% confidence interval, 3.4-10.1; P < .0001). CONCLUSION: The number of patients who received fertility-sparing treatment for endometrial cancer or atypical hyperplasia increased over time. However, the proportion of women who experience a live birth following these diagnoses is relatively small.

Clinicopathologic characteristics and treatment features of women with the incidental diagnosis of endometrial adenocarcinoma during infertility follow-up in Ankara, Turkey.

OBJECTIVE: The aim of this study was to investigate the clinical and laboratory features of patients with the incidental diagnosis of endometrial adenocarcinoma (EC) during infertility work-up, with special attention given to treatment approaches, recurrence rate, and fertility outcome. MATERIAL AND METHODS: The medical records of 577 patients who were diagnosed with EC and treated between 2007 and 2013 were included in the study. Out of 577 EC patients, 5.1% (n = 30) were ≤ 40 years of age. However, 10 patients had a history of infertility and had been diagnosed during evaluation for infertility. Patients' clinical and laboratory data were reviewed retrospectively. RESULTS: The mean age at diagnosis was 34.3 ± 4.5 years and the mean duration of infertility was 5.1 ± 4.7 years. Immediate staging surgery was performed on three patients. The others were treated with oral megestrol acetate and/or a levonorgestrel-containing intrauterine device (IUD) for 6 months. The mean duration of postoperative or postdiagnostic follow-up was 44.7 ± 25.9 months. The disease persistence and recurrence rates were 11.1% and 22.2%, respectively. Two patients achieved pregnancy naturally or by assisted reproductive technology (ART) trial. CONCLUSION: The investigation of patients during infertility work-up provides an opportunity to evaluate the endometrium and its malignancies in young women, when the disease is in its early stage and symptom free. The standard surgical treatment for early-stage EC is total hysterectomy with bilateral salpingo-oophorectomy. However, conservative management of early stage EC with progestational drugs, especially in young patients who wish to preserve their fertility, is acceptable with the possibility of future pregnancies.

Fertility-conservation combined therapy with hysteroscopic resection and oral progesterone for local early stage endometrial carcinoma in young women.

OBJECTS: This paper explored the suitable population for the combined therapy of hysteroscopic resection and oral megestrol acetate (MA) to treat local stage I endometrial cancer. Therapeutic effectiveness, safety, as well as pregnancy rate and relapse rate after treatment were also examined. The aim was to provide guidance for the treating similar cases in the future. METHODS: This perspective study analyzed the clinical data of early stage endometrial cancer patients who have received combined therapy of hysteroscopic resection of local endometrial lesion and oral administration of MA at the Obstetrics and Gynecology Hospital of Fudan University, Shanghai. RESULTS: A total of six patients met the entry criteria and were enrolled into the trial. All of them achieved a pathologic complete response to hysteroscopic resection of local lesion combined with oral administration of MA for 3 months to 6 months. Among the patients, three became pregnant after natural conception and had healthy infants delivered vaginally at full term without assistance. No relapse occurred in the follow-up study over 48.5 months on average. CONCLUSIONS: In early-stage endometrial cancer, young patients who had already given birth demand may receive hysteroscopic resection combined with oral administration of MA as conservative treatment. The patients can consider natural conception after complete remission, but a close follow-up was crucial to ensuring that the patients were free from other factors affecting childbearing ability.
