BACKGROUND: To evaluate the outcomes and management of pregnancy after transcervical resection of the endometrium (TCRE). METHODS: Retrospective study of 39 pregnancies after 1621 procedures of TCRE. RESULTS: Among 1621 women who were successfully followed up after TCRE, there were 39 pregnancies in 32 women, including five ectopic pregnancies (12.8%) and 34 intrauterine pregnancies (87.2%). The majority of pregnancies (84.6%) occurred within the first 2 years. In the first year after TCRE, the incidence of pregnancy was 1.5%. In women who had amenorrhoea after TCRE, the chances of conception (2/676; 0.3%) were significantly (P < 0.001) lower than for those who continued to have period (30/945; 3.2%). Thirty-two cases with intrauterine pregnancy were terminated under ultrasound guidance with two difficult procedures. Only one pregnancy in our study resulted in spontaneous miscarriage which was managed by suction curettage. One term pregnancy had placenta increta resulting in Caesarean hysterectomy. CONCLUSIONS: Pregnancies after TCRE are associated with increased risk, and clinicians should be aware of the various complications of pregnancy that may occur after TCRE, including an increased risk of ectopic pregnancy. Surgical termination of pregnancy after TCRE is potentially a difficult procedure and should be carried out under ultrasound guidance.
BACKGROUND: The aim of this study was to evaluate the expression of Bcl-2 and Ki-67 in tamoxifen (TAM)-associated endometrial polyps and postmenopausal polyps. MATERIAL AND METHODS: For this purpose, a retrospective analysis of paraffin-embedded specimens was carried out. Polyps of 20 postmenopausal and 14 TAM-treated patients, 11 simple endometrial hyperplasia, 10 atypical complex endometrial hyperplasia and 8 endometrial adenocarcinoma specimens were included in the study. Hematoxylin/eosin-stained sections were evaluated. Immunohistochemical staining was performed to investigate the expression of Bcl-2 protein and the Ki-67 proliferation index. RESULTS: There was no statistically significant difference between the 5 groups with regard to Bcl- 2 staining (p > 0.05). However, Bcl-2 expression in TAM-associated polyps was higher (86%) than in the postmenopausal control group (80%). Positive Ki-67 was highest in the endometrial adenocarcinoma specimens, followed by the atypical complex endometrial hyperplasia group (p < 0.0001). Compared to these 2 groups, Ki- 67 expression was lower in TAM-associated polyps, but Ki-67 indexes were significantly higher in the TAM-associated group than in the control group (p < 0.0001). CONCLUSION: Since TAM-associated polyps tend to have higher proliferation indexes and Ki-67 ratios than control groups, we suggest that they are likely to have a higher malignant potential.
