The current study investigated the effect of laparoscopy on the biological behavior and gene expression of endometrial adenocarcinoma cells. Totally, 40 patients with stage I endometrial adenocarcinoma and 20 patients with benign uterine diseases were enrolled in this study. For patients with endometrial adenocarcinoma, laparoscopy was performed in 20 cases and laparotomy was carried out in the other 20 cases. Total laparoscopic hysterectomy was performed in patients with benign diseases. Cell apoptotic rate and the gene expression of N-myc, Fas, metastasis-associated protein 1 (MTA1), and nm23-H1 were determined in the normal and cancerous endometrial tissues both preoperatively and postoperatively. For endometrial adenocarcinoma cells, laparoscopy, instead of laparotomy, promoted the apoptosis of endometrial adenocarcinoma cells, down-regulated the expression of apoptosis suppressor gene N-myc and metastasis-promoting gene MTA1, up-regulated the expression of apoptosis-promoting gene Fas and metastasis suppressor gene nm23-H1. However, laparoscopy did not affect the apoptotic rate and gene expression in normal endometrial cells. Laparoscopy may be used as a safe and effective intervention for endometrial cancer.

Background: Endometriosis is a common condition with a rare malignant potential. We report a case of a patient with a colon mass who underwent surgery for malignant endometriosis associated cancer.Case: A 70-year-old woman with a pelvic mass who was lost to follow-up for 6 years represented with an enlarging pelvic mass involving the sigmoid colon.

Medroxyprogesterone acetate (MPA) is a promising fertility-sparing treatment for early stage endometrial cancer; however, it has a high recurrence rate and is inferior to surgery. Although the site of recurrence is mostly the endometrium, we here report a case of metastatic recurrence to the para-aortic lymph node with endometrial recurrence despite a careful follow-up. A 31-year-old woman was diagnosed with grade 1 endometrioid carcinoma, stage IA without myometrial invasion.

Clear cell adenocarcinoma of the cervix (CCAC) is a rare subtype of cervical adenocarcinoma. It has been linked to intrauterine exposure to diethylstilbestrol (DES) but can happen in non-DES-exposed patients, albeit less commonly. Presentation is largely vaginal bleeding, emphasizing the importance of considering CCAC in the differential of abnormal vaginal bleeding despite the tumor's rarity.

Introduction: Incidence of endometrial cancer (EC) in Hispanic/Latina (H/L) women are higher compared to other race/ethnicities in the United States. EC is the third most common cancer and the fourth cause of cancer-related deaths in Puerto Rican women, yet demographic and clinical information is limited. High rates of EC risk factors such as obesity, diabetes mellitus type 2 (DM2) and hypertension (HTN) have been documented in the Puerto Rican population.

Objective: This study aimed to compare clinicopathological characteristics and oncological outcomes in patients with endometrial cancer aged ≤45 and >45 years, with a focus on identifying distinct traits and prognostic factors in younger patients.
Design: A retrospective cohort study.
Setting: The study was conducted at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, with a restricted study population from 1996 to 2016.
