Stage III and IV endometrial cancer: a 20-year review of patients.

In advanced endometrial cancer, the importance of peritoneal cytology and optimal surgical cytoreduction remain subjects of discussion. We evaluated our clinical experience of 67 patients with FIGO stage III and IV endometrial cancer treated in the Erasmus Medical Centre in Rotterdam over a 20-year period with an emphasis on stage IIIA disease based on positive cytology only and optimal cytoreduction. Lymphadenectomy was not routinely performed and peritoneal cytology was examined in 74% of the patients.

Recurrent endometrial cancer: a retrospective study.

Objective: The value of follow-up after treatment for endometrial cancer will be discussed.

Study Design: We evaluated our clinical experience, including mode of detection, of patients with recurrent endometrial cancer treated in the Erasmus Medical Centre in Rotterdam over a 20-year period. Clinical data and histopathological features from 64 patients were analyzed.

Growth regulation and transcriptional activities of estrogen and progesterone in human endometrial cancer cells.

Estrogen-stimulated growth of the malignant human endometrium can be balanced by the differentiating properties of progesterone. To study the molecular basis behind this, gene expression profiling was performed using complementary DNA microarray analysis. In this study, the human endometrial cancer cell lines ECC-1 and PRAB-36 were used as models.

Progesterone-induced inhibition of growth and differential regulation of gene expression in PRA- and/or PRB-expressing endometrial cancer cell lines.

Objective: Progesterone plays an important role in controlling proliferation and differentiation of the human endometrium. Because there are two progesterone receptor isoforms (PRA and PRB), it was important to generate tools to be able to study the role of these two progesterone receptors separately.

Methods: Using stable transfection techniques, both human progesterone receptor isoforms (hPRA and hPRB) were reintroduced into a hPR-negative subclone of the well-differentiated endometrial cancer cell line Ishikawa.

Differences in invasive capacity of endometrial cancer cell lines expressing different progesterone receptor isotypes: possible involvement of cadherins.

Objective: Loss of expression of progesterone receptors (PR) in endometrial cancer is related to a more invasive and metastatic phenotype. In this study we aim to investigate whether selective loss of PRA or PRB affects the invasive capacity of endometrial cancer cells.

Methods: cDNA microarrays were performed to compare gene expression profiles of a set of endometrial cancer sub-cell lines expressing PRA and/or PRB.
