Human gene icb-1 (C1orf38) has been initially cloned by our group from endometrial adenocarcinoma cells. In this study, we examined icb-1 expression in 90 endometrial cancer and normal endometrial tissue specimens. Expression of icb-1 was significantly (about 3.5-fold) higher in endometrial cancer than in normal endometrium (p <.0001). Determination of various molecular markers revealed that only Ki-67 expression differed between both groups in a similarly significant manner. Furthermore, we observed a highly significant positive correlation of icb-1 transcript levels with c-erbB2 (HER2) expression (p <.0001). Our data strongly encourage further studies on the function of icb-1 in 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.
