Maspin is a member of the serpin family, whose expression is altered in neoplasia and malignancies of many tissues. Underexpression of maspin has been reported in breast and prostatic cancers, but in some cancers such as ovarian, colorectal and pancreatic carcinoma, it was found to be up-regulated. This study aimed at demonstrating the expression of maspin in human endometrial tissue and searching for any altered expression in endometrioid adenocarcinoma of the endometrium compared to normal endometrium. The expression level of the maspin gene was studied using reverse transcriptase-polymerase chain reaction (RT-PCR) performed on RNA extracted from 34 endometrial cancer samples (including 24 with FIGO stage I disease and 10 with FIGO stage III disease) and 28 normal endometrium in proliferative or secretory phases. Immunohistochemical staining was also performed on 10 cases of endometrial cancer (6 FIGO stage I cases and 4 FIGO stage III cases) as well as 15 normal endometrium. Semi-quantitative RT-PCR revealed that the expression of maspin was significantly up-regulated in both stage I (p<0.01) and stage III (p<0.01) endometrial cancer compared with normal endometrium. However, no significant difference in maspin expression was demonstrated between stage I and stage III endometrial cancer. Immunostaining of all tissue sections revealed an immunopositive signal in the nuclei of the normal or cancerous endometrial glandular cells. In 60% of the cancer cases, cytoplasmic staining was also evident. Our results suggested that there is up-regulated expression of maspin in endometrioid endometrial adenocarcinoma. Cytoplasmic immuno-expression of maspin is common in endometrial cancer. It may play a role in the malignant transformation of human endometrial tissue.

Paclitaxel and carboplatin (TC) chemotherapy is an effective and well-tolerated regimen against advanced endometrial cancer. Organic anion transporting polypeptide 1B3 (OATP1B3) and copper transporter 1 (CTR1) are critical for the uptake of paclitaxel and carboplatin, respectively. This study aimed to address the prognostic impact of OATP1B3 and CTR1 in endometrial cancer patients treated with adjuvant TC chemotherapy. We immunohistochemically evaluated the expressions of OATP1B3 and CTR1 in 47 stage III endometrial cancers. The high expression levels of OATP1B3 were significantly correlated with type I tumor (P = 0.0005). In univariate analysis, high expression levels of OATP1B3 (P = 0.047) and CTR1 (P = 0.009) were significantly associated with longer disease-free survival (DFS) and longer overall survival (OS), respectively. The patients with tumors showing high expression levels of at least one of OATP1B3 and CTR1 had potentially longer DFS (P = 0.058) and significantly longer OS (P = 0.003) sin the univariate analysis. Combined OATP1B3/CTR1 expression was the sole independent prognostic factor for longer OS in the multivariate analysis (P = 0.013). Our findings suggest that combined OATP1B3/CTR1 expression is a possible predictive/prognostic factor for a good outcome in stage III endometrial cancer patients treated with adjuvant TC chemotherapy.

Objective: Obesity is one of the common risk factors for developing of endometrial cancer and is negatively associated with its survival, although this result is controversial. Endometrial cancer stages range from stage I, which has better clinical outcomes to stage IV, which has poorer clinical outcomes. Endometrial cancer traditionally divides into type 1 and type 2 dependent on histology which has different clinical outcomes. In this study we investigated whether obesity is associated with the stages of endometrial cancer taking into account subtypes of cancer and menopausal status. Methods: Data on 1,104 women with endometrial cancer were retrospectively collected from the largest women's hospital in China and analysed. Data included age at diagnosis, body mass index (BMI), histology of cancer and menopausal status. Results: The BMI in patients with stage I endometrial cancer was significantly higher than that in patients with stage II or III or IV (p=0.0001). However, there was no statistical difference in BMI between patients with stage II, and stage III endometrial cancer. This negative association was persisted with type 1 and type 2 endometrial cancer (p=0.1989) and premenopausal and post-menopausal status (p=0.4342). In addition, the proportion of over-weight or obese women in type1 endometrial cancer with stage I was not different to type 2 endometrial cancer with stage I. Conclusion: Our data demonstrate that BMI is negatively associated with endometrial cancer in early stage regardless of subtypes of cancer, menopausal status and obesity may be also a potential risk factor for developing type 2 endometrial cancer.
